To many perfons fuch an intimation is unnecefTary, and probably it would not have been given (for nothing can prevent cavil- ling and ill-natured conftrudtions) but that one or two to whom the manufenpt wa fhewn, although they were Callico Printers, 1 B began INTRODUCTION. began to confider it more like critics ; con- fequently their further perufal of it was diC penfed with, and the Copy referred to a friend or two, of difcernment enough to confider the critical quality, in this cafe, only as a fecondary one ; and that the end of the publication would be anfwered, if the contents were rendered intelligible to thofe forwhofe ufe they were intended. It is likewife fuggefted, that as this is th e iirft publication of the kind, and indeed the firft ever offered concerning Callico Printing*, the Writer had nothing but his own ideas to adopt and arrange ; it therefore followed that it was proportionably laborious; * The Writer has heard of fomcthing of this natur* in Franc*, but he underflands it to be more a defcriution of the bufmefs than on the plan of this publication.— He howerer, will not infill that his is the only one ; he m»y poffibly be miftaken, although he has clofely enquired concerning it« a.nd, INTRODUCTION. and, however lightly fome may think of the affertion, laborious it certainly was ; hence he, with fome confidence, conceives that any perfon, unlefs pre-determined to view every thing unfavourably, will make the neceflary allowance for whatever may not be fo clearly exprefTed, or fo methodically arranged as it might be, and with equal in- diligence, excufe the infertion of what may appear of too little importance to have been remarked, or be perhaps repeatedly fpoken of, as well as the omiffion of what might have been inferted, either through inadvertency, or as not having come within the fcope of his obfervations.

By a good Pattern-Drawer mould be under- wood one, who pofTeiTes a fertility of invention, with judgment to adapt that fertility to the beft £ 3 purpofe Of Pattern - Drawing. purpofe, as it regards tafte, effect, execution and expence ; or at lead, one who can improve on what is doing by others, or can readily catch the reigning ftyle, and by adopting it, form his defigns accordingly. He fhould likewife have a knowledge of the bwfinefs in every ftage of its procefs, and confe- cmently be enabled to anfwer, in fome degree, how every intended effecT: may be obtained pre- vious to the executive part being put into operation. Hence the Writer ventures to fay, that how- ever excellently a Drawer can copy nature, or combine a number of colours, yet, if that be all, his utility is very limited, when compared with him, who without great neatnefs of drawing or brilliancy of colouring, can produce that variety which gives a fpring to a bufinefs, ever dependant on the capricioufnefs of tafte, and the hcklenei's of fancy. It may neverthelefs be obferved (making a tranfition from Pattern-Drawing to the Patterns themfelves) that it is difficult to fay, what really constitutes a good pattern, as decifions on that fubjed are formed by different perfons from very different motives ; for inftence, a Draper's deter- mination- Of Pattern & rawing. mination of one is biafTed by what will heft fuit his line of trade ; a Printer's, that which is adapted to produce the defired effect at the leaft; expencc ; while a buyer's opinion is guided by what is moft generally exhibited in the mops ; and many patterns acquire the character of being good ones, merely from a Draper having it in his power to command a general difplay of them, under every advantage ; for the moft fanciful and bell executed pattern would have little chance of felling well, if feen butin a few places, or the fale not otherwife forwarded; as it then would not have the appearance of a generally approved one, and confequently it would be difregarded in a proportionate degree. But, as this will be occafionally confidered in other places, a few fentiments refpecling Genius, Fancy, and Invention, as more immediately the fubjecl: of this fection, will be now offered; as well as what thofe helps are,of which genius may avail itfelf, toward directing its progrefs ; with the needfulnefs and means of retraining its impe- tuofity, or preventing its eccentricity : fome other thoughts will likewife be advanced^ rather more remote to the immediate fubject, but /till having fo much affinity with it, as to come under the § cognizancp Of Pattern Drawing* cognizance of a Defigner, or thofe who have, or defire to have, any concern in that department. But, it may be necefTary to obferve, that as the fubjecl; gives rife to feveral obfervations, not fufficiently clofe to be interwoven with it, there- fore,for the fake of being as methodical as poflible, and the keeping together what is more immedi- ately to the point, they will be referved for the EfTay further on. ~— Previous likewife to what will be faid in this, and the following fecYion, relative to pntting-on the block, the writer intimates, that, to avoid confufion of terms, when fpeajting of Pattern- Drawers, he fhall moft frequently call them De- figners; patterns he fhall call defigns; Putters-on the Block he fhall call Drawers; and their performances putting-on ; but, in difplaying the rules, fuch diftinction will not be affected, as he ihall ufe them indifferently as belt fuits the im- mediate purpofe. As for the terms Genius, Invention, and Fancy, though diftincT: ones, Fancy will be moft likely adopted to ferve for either, as being moft applicable to d^efigning for Callico-printing. IN Of Pattern Drawing* IN the beginning of this feaion, it being faid a deal depends on Genius in regard to the fubjeft now in view, it may be expedcd, that, preparatory to what will be exhibited as mecLwiical helps to it, fomething will be faid wherein it confifts, how it is to be improved, what aieits indications, and the like; it will therefore be atte.apted, not as afpiring to any thing dotfrina!, fpe- cincally defcriptive, or as feeking controverfy, but only as it fcems to hold a connection with the fubjea treated of; for, till terms are ex- plained, underftood, and univerfally received in one unequivocal fenfe, we animadvert in the dark, hence to afk whatGenius is,howit originates, how it performs, or where is it feated ? leads into fuch metaphyfical obfeurity or perplexity, that the raoft intelligent are at a Iofs how to fatisfy fuch inquiries ; for knowing little of the elementary principles of things, as the fourcesare fo remote, how can pofitive or clear confequences be educed? therefore we fit down atlaft with fimply calling it a faculty of the mind, and toexprefs its operations, fay fomething like what is ventured to be offered further on, taking certain pofitions as principles or maxims, and accordingly dravf cmr deductions and argue from them. As Of Pattern Drawing, As for the difplay or produaions of genius or fancy, enough is vifible in every ftation, and therefore though only treating of pattern -draw- ing, an occupation of little worth or merit in the eyes of thofe who hold a high rank in the fcale of artifts, as if requiring little ftrength of intel- lea, compafs of invention, or accuracy m execu- tion ; yet, in its proper fphere, taken in all circumftances, it is with thofe whom it immedi- ately concerns, of as much importance, and as difficult to attain, as many arts or fciences that are univerfally dignified. Genius in any fhape, it is obferved, is not fatif- fied unlefs exploring unbeaten tracks, or rendering that perfea which cannot be rendered fo by the efforts of mediocrity ; to conftitute which and to empower it fo to aft, there mufl be fancy, judg- ment and tafle : by fancy, various ideas feem to be carried to the mental repofaory and there ftored up to be occafionally made ufe of; but ' then fancy mould be reflrained or governed by judgment, or its emanations will be eccentric or extravagant ; and this faculty of judgment feems to be properly employed in going through its colleaion of ideas, to fcparate or arrange them as maybe required; or in other words, judgment is a Of Pattern Drawing* a kind of counterbalance to the eccentricity of fancy, curbing it (as before intimated) when im- petuous, and guiding it when prone to deviate. Further, As judgment is chiefly underftood to keep the fancy within proper bounds, "fo that no- thing be unnatural or diftortive ; another power is requifite to render whatever is produced, not merely free from fault, but to give it a beauty, and an elegant and highly polifhed finifti ; which power is generally expreffed by the term tafte ;. of which much has been written to define, and to bring under certain rules, but with little effect, bein'■<* ■ ^__j vy accidc "*' f ^2SL by nature, and partly depending upon circum- ilances not always regulated by Uriel: propriety % but as it takes in the consideration or knowledge of v/hat is generally, and (in feme cafes) uuiver- fally, allowed to give a (mill* to the works of art; it is therefore able to form a deeifion, either -is applicable to the performance under the defigneis hands, or in determining on the works of others: Tafte. however, according as it is employed, is either fuperior, or Subordinate to judgment ; as the arbitrator of ornament, it is defpotic; but in following nature, it muft be fubjc&ive ; hence, according as the fancy or judgment is likely to be Of Pattern Dra wing, be employed, let the defigner attend to this dif~ tindrion, as, in the inftance of pattern-drawing, tafte is to be underftood as the uppermoft quality to be acquired, nature being no way in that bu- finefs likely to be very clofely imitated ; but in other fituations where the performance confifts in its refemblance of nature, and th.it refemblarceis required, there, judgment (with tafte however at its call) muli claim the precedency or firft notice. Again, Either of thefe three qualities is of little fervice without the affiftance of the others, fancy alcne being" verv ipaiWiu^ tg to nrodure what is requifite (even when required to be wild or grotefque) For though its productions may pleafe, it can be but for a moment ; but, when Tcgulated by judgment and adorned by tafte, it ilrikes almoft univerfally; the decorative part pleating thofe who know but little, or overlook that of the natural ; and thofe who look for propriety, find it, with the addition of that heightening or vivification which true tafte imparts; for when thefe are united, they of courfe ftrengthen and add to each others power and effect, exhibiting fomething novel, exprefted with propriety, and embellifhed with elegance ; genius, which is the vivifying Of Pattern Drawing* vivifying fpark, giving a fpring and fpirit to the whole; and without which, the moft elaborate works of judgment will never give muchpleafure to any one of a refined and comprehenfive turn, though for a while they may pleafe a frigid obferver. It is not the bufinefs of this little effufion to particularize the indications of genius further than as immediately applicable to the mechanical operations difplayed further on ; the writer how- ever will juft mention that many have been de- ceived by an early indication of fuch a gift, forming great expectations, that when ripened, it- would acquire much celebrity ; but, it is not eafy in juvenile objects to fay into what road it may hereafter ftrike, for until their production? may be fuppofed to be regulated by that degree of difcernmentjwhich requires fome maturity of years, there can be little of what is termed judgment :• hence many youths have been put to defigning though it has afterwards appeared their talents have been much over-rated ; and in deciding on fuch indications', a caution fhould be obferved, for though genius may feem to improve as matu- rity approaches ; yet ere that epocha commences,, it may have pafled its meridian ; which is {een , frequently^ Of Pattern Draivhg* frequently to be the cafe, whenever a remarkable early difplay of genius has been vifible : befides, people who thus haftily decide, are not aware, that while they do not expe& a perfect perform- ance, and look but for an attempt, they only commend its proximity to perfection ; but when the time comes that fome'thingmaflcrly ihould be produced, the performer may fliew that his geni- us was not of the kind to arrive at that height; and then, thofe who predicted great effects, are proportionably difappointed and mortified. * It is impoflible to fpecify all the impediments to a lad's improvement, or the helps he may re- ceive, a deal depends on either ; for inftance, a youth with ftrong indications of genius may be placed where there is no one proper to cultivate it, the fituation* or courfe of wcrk may not be congenial * This may be alluded to a« particularly appli- cable to lads being put out to Pattern-drawers who work at home (and it holds good refpe&ing Cutters and Engravers) though this is an error in thofe who put them out ; for when out of their times they have in effect another term to ferve before they know any thing beyond the ufe of the pencil, the knife, or graver, otherwife than by mere precept ; and, of courfe, can be but of proportionate fervice at a manufactory. Of Pattern Braivlng. congenial to his natural aptitude, or lie may be precluded thofe circumftances which are necef- fary to give him confidence, and improve his underftanding in general matters ; thefe arc points (lamentably for the youth) too often to- tally disregarded,--- -and from thefe and other rea- fons, it may be advanced, that there are fo very- few good pattern drawers, (according to the de- finition juft given) though fuch numbers have ferved as apprentices, or been pupils to pattern drawing, and this leads to fay, thinking how for- ward many are, to take pupils or apprentices to drawing (leaving the iv eighty confederation of premiums out of the queftion) that thofe who have youths to put out, and thofe who are incli- ned to take them, fliould not be very prompt either way, from the con fi derations mentioned above, as well as what follows ; for it is of little fignification to fay, that fuch a lad fhews a great genius or tafte for drawing, or any bufinefs de- pending on fancy, unlefs there is fome indication. of an understanding equally acute and compre- henfive in general matters, with other concomi- tants of vivacity, good difpofition, and a plaftic temper; as then, and then only, there feems hopes of his genius, whatever bent it may take, furnifh- ing itfelf in its approaches to maturity, as cir- cumftances offer, with every reauifite towards improving Of Pattern Drawing* improving it, and that without the formal impofiti- on of precept, rule, and frigid advice ; confequently when arrived at that age, in which fomething beyond a mere effort is expected, his own hopes and views, as well as thofe of others, will not be difappointed. * It is begged that what is above advanced be not understood as giving into the common mode of inveighing againft taking apprentices, from the probability of leflening the value or fcarcity of defigners, who have pafTed their noviciate (as may likewife be faid of other branches) what has been faid, is more directed to parents, who are prejudiced *in favor of their children's talents, or through fondnefs miftake their inclination for genius, for unlefs a lad is likely to fhew thofe faculties which will get him through life with credit and eafe as an artifi: (in which clafs de- jGgners may be included) he had better be put to any common mechanical .employment, as certainly nothing can be a greater mifery to a man, than to think~his living depends upon the productions of fancy, and he is unfortunate enough not to poffefs a fingle ray of it, and that*. confequently,his utmofl exertions are defpicable, and of couife not worth exhibiting. The m Of Pattern Drawing, The writer will now endeavour, perhaps not over methodically, to throw in fuch documents as feem to him moft likely to affifl: the fu'ncy in its exertions, and with fuch remarks as occafion- ally arife, either as more or lefs applicable to the defigner or his employer ; and before he fpeaks of the mechanical parts of defigning, he will dwell a little on fome circumftances not totally irrevalent to fuch employment, and probably not abfolutely unworthy the notice of either party; for, though the aim may be miffed, the intention is to render the performance more eafy to one party, and confequently more advantageous to. the other. In the firft place, it is fuggefted, a Defigner ought not, by any means, to be confidered in fo mechanical a light, as if fancy or invention were of fuch a nature, that he can at all times command a fuccefsful operation *; fimilar to a perfon 3 Thofe are particularly alluded to here, who are engaged as Defigners to work a ftated number of hours in a 3ay.

Of Pattern Drawing. pcrfon performing a merely mechanical piece of work, in which little more than utenfils are needful, and the fubje& to be a&ed on is imme- diately and conveniently at hand. To illuitrate which, it may be obferved, that Principals them- felves, at times, afFe£ to fay, Defigners fhould only work when fo difpofed, yet many of them, inconfiftently with fuch a pofition, think nothing done unlefs they fee fomethingon paper ; making hardly any account of what the invention is at work upon ; but, contrary to this practice, it is here faid, that the defigner mould not be afked, except on lingular occafions, how he means to do fuch a part ? what will be put in this or that place ? what will be the colour of this object ? and foon ; but that a proper mode is, (when not left entirely to work from his own fancy) for him to be told what fort of patterns is wanted ; on whichjhe accordingly draws a number flightly, or perhaps nearly perfect, agreeable to the nature of them ; from thefe a feledtion is made as hav- ing the beft effect ; afterwards another is made, including that quality, with their adaptation for working ; and even from thefe it may be needful to make a felection as proper to jQiew, or to be put into execution. All Of Pat lev n Drawing, All this is however offered as matter of opinion, or only to be put in practice where and when it can be done conveniently, as at all times and in all places it cannot, neither is it always ne- ceflary ; but this is however infifted on, that a Defigner can do little with pleafure to himfelf at a Printing-ground, if under reftraint, or fubject to that kind of controul, or enquiry, which has been exprefled above ; or if his employer be of that caft, who confider all under them as but mere machines to procure themfelves profit, and that as fach, they have nothing to do but to fpur every one on by any method, however coarfe and unfeeling. RefpedYing this operation, and indeed any other, it may likewife be noted, that one perfon only is prober to give orders (no matter how many have been previoufly advifed with) for rarely do two or more agree in opinion ; and for a defigner or any other to receive orders from feve- ral, and thofe orders different, or countermand- ing, no one need be informed, is productive of much embarrafTment, and often fubverfive of what each party defires. But turning now to the immediate fubje& of this fe&ion, and in particular alluding to fancy, it I Of Pattern Drawing.. it is fuggefted* that every one is prejudiced in favor of his own ideas, or what he concludes or wifhes to be underftood as fuch, Principals are particularly prone to be much in love with fuch apparently new ideas, and not being always un- der the neceffity of confulting any one, they often adopt and put in execution, too precipi- tately, what has ftruck them as valuable ; not difcovering how they have deceived themfelves, till they find no other perfon feems ftruck by its appearance when difplayed, as they were by it in idea ; for if they firfl fpeak of fuch an idea to their fubordi nates as very finking, they not being always at liberty to pafs fentence, or even give their opinions with that freedom which the prin- cipal can and will on what they might offer, the infatuation does not go offfo foon, nor is it feen as fuch till too late. - Drapers like wife frequently getting hold of an idea, adopt it as a good one, and endeavour to communicate it- (perhaps with a friendly inten- tion) but are often greatly difappointed when what is drawn in confecjucace of f uc h communi- cation tap Of Pattern Drawing, cation does not give the effect they want*. A. great deal of time, trouble, and other incon- venience would however certainly be prevented, by letting thofe wonderfully flriking ideas reft a little till thought of more coolly ; and then, if no dimunition happens in their apparent value, or * The above fuggeftions lead the Writer to ob» ferve that fome will fay tif they could but ufe the psncil, they are fure they could produce fomething wonderful new, and flriking in effeft !— to coirifcat unthoughtful prepofleflions of fuch a kind the writer knows would be to little purpofe ; he will only fay of this, that he who advances fuch a notion, can know nothing of the operation of the inventive fa- culty in fuch a cafe, and of courfe does not diftin- guilh between a certain end or point reprefented to him by the livelinefs of imagination, diverted of all obftru&ions to its appearing fo forcible in novelty and effeft, and the operation neceffary to produce or difplay it on paper by a mechanical or manual proeefs, with the ufual interruptions of objections, impediments, revifwns, diflatisfaftions, &c. ■ Of Pattern Drawing* or ideal effect, there is the greater probability of their fucceeding and itriking more univerfally.* It often happens too, that many (Drapers particularly) are violent in requiring fomething new, * Speaking of this infatuation in favour of (elf- created ideas, the following little anecdote is offered, and which {hews at the fame time how with a little finefle, a weak fide may be played with : A perfon having to (hew a number of patterns, as townfman (when it was the cuftom to take a quantity of patterns only at Hated times, and after (hewing them, to make them general) having difplayed them before a Draper, He, after praifing Come, and rtejecling others, faid of one, that if altered in fuch a manner"it would be much better; the perfon who (hewed the patterns, willing to tempo- rize, told him his obfervation was judicious, and added, to heighten the flattery, that feveral others had made exaftly the lame obfervation ; this fo pleafed the Draper, that he fet about altering every one cf the patterns in the fame judicious (tile, and took fuch pleaiure in his employment, and retained the other fo long, that he had little time to go elfe- where that day, refolving to take care for the future, how he commended the alterations fuggefted by the fame perfon again. *r Of Pattern Drawing* new, or totally different from what lias ever been feen; all this has a bufy found, and in idea promifes great deal, or at leaft implies the hope of a great deal ; but could it be procured, the expectation might not be anfwered, as it generally. feems that when any thing happens to be produced, very different from the common run or appearance of work, or what may be called the reigning ftyle; it has not the chance of getting into vogue, for reafons already given, except when a Draper of eminence, who holds his connections as it were by a bridle, is determined to pufh what is a favourite of his; though even that will not always fucceed ; for fomehow or other capital blunders a re now and then made by the moft experienced, -#• in the chufing of patterns. Cautious Drapers however are not very forward in this refpect ; they know, indeed all mull, that though at all times there are certain claffes of patterns that enfure fale, yet a continuation of one frile, will tire in time ; and the utmoft efforts to continue it, will not always be propitious ; * for innova- tions * This may be illuflrated by a capital connection in town, fruitlcfsly attempting li Of Pattern Drawing* tions in ftyle, rarely happen abruptly ; they are brought about by flow degrees, or in fa €t more by accident than defign, and oftentimes in a manner contrary to what any one might con- ceive. Much, to be fure, is fometimes faid of the licklenefs and whimficalnefs of Drapers and others, but there furery is little caufe, it being natural to be tired of any thing ever fo excellent when very familiar, and of courfe novel or diffe- rent appearances are fought after ; but when interefled views are annexed, and thofe variations cannot be fufficiently obtained, it is juft as natural to repine. There was a time when no one thought grounding off the table could be performed as it now is ; the writer well remembers when it was in agitation, to print two reds and two olaves at the houfe where nrft executed *. All the Printers exclaimed that the two after-colours could never be put in according to the defigns ; it attempting for two or three fcafons to force ftripes into vogue ; but though the work was generally good, the effort fubfided under the prevalency of a different ilyle. f This was at Weft-Ham, Effex. ■P Of Pat urn Drrwing. it was however attempted, and it fuccecded, and nothing but that courfe of work was done there that feafon. The next feafon, indeed fhortly after, it was attempted at other places; and now little difficulty (comparatively fpeaking) is ex- perienced in it. ' It may likewife be faid of black, dove, and yellow patterns ; at firft the grand objection to executing them was that a black could n^t be procured ; hence when dove was introduced, it was done off the table, by thofe, who wedded to the old fyflem, execrated an innovation, which then, for the honour of a good black, appeared discreditable ; but others, who were lefs tenacious of fuch honour, as well as for other fufficient reafons, foon brought that courfe of work into vogue ; and now, or at leaft very lately, what courfe was more general ? it may be faid too, in fpeaking of black, that formerly it was a maxim no pattern with a mixture of colours would do without it ; but it is not thought fo now. What the writer has now to advance, as rules or documents reipecting defigning, would follow here properly enough, but having little to advance, and that little not fatisfa&ory even to Of Pattern Drawing* to himfelf, he will defer it to the end of the fecYion ; obferving however, as leading to what he means to fay about Genius, Fancy, Invention, and .drawing, that more might very probably be faid or advanced as Rules, but Genius or Fancy cannot be dictated to ; Fancy mull, in many cafes, be left almoft intirely to itfelf, as not coming under a mechanical defcription, or ana- lysis : much to be fure may be faid, and pretty difquifitions have been given, (perhaps thefe in this article are of the number) about judgment presiding with coolnefs, while fancy is wandering here and there ; then tafte is ufhered in to the nfiiftance of judgment, and fo on ; but he is in- duced to think, that in genius is comprized that faculty which foon avails itfelf, whenever op- portunities happen, of what is neceffary to ren- der its emanations effective ; in fa&, Rules impoled on a natural genius, too often fhackle it, and it is almoft proverbial, that true genius foar s above all precept, and looks with a becoming difdain at the formality of rule ; often producing what never would have appeared, if rules autho- ritatively given, had been clofely adhered to ; and it may be faid, when Fancy fuffers itfelf to be pinned down to Rule, it is to be fufpedted there is not a great deal of genius, and that thofe who can produce little ' without certain rules to lead Of Pattern Drawing* lead them, are not much better than copyifh of imitators ; but turning to the point in view, which is the province of fancy, namely, defign- ing, it is o»ly at certain times that it is alive,* and then it defpifes fetters ; when it is not free, like every thing elfe in diftrefs, it catches at any amftance, and is thankful for any help that offers itfelf. Fancy notwithstanding, fhould be (as before faid) at all events, free from certain impediments or reftraints ; which applying to a Defigner's performance at a Printing-ground, can hardly be done; from the mind being confufed with various confiderations, that obftruct or divert its efforts, fuch as receiving orders from feveral, murmurings at not always fucceeding, being forced to do duty at all times, and the like ;f but •■ What is a man's genius or fancy worth, when diitrefled, brow - beaten, or otherwilc illiberally treated ? and how little do many think of what are often the real caufes of the great difference which at times appear in the works of men of genius ? f Thefe may fecm to many but trivial obfer- vations, the writer however, from experience, knows the contrary ; and he is certain fome others in the moft eligible fituation as engaged Defigners, know the fame ; indeed an engaged Defigner at a Printing- Ground is now little more than a Compiler.

As for invention, ftrictly fpeaking, it is not here offered to fay what it is, much lefs how to de- fcribe it; there is a mutation of ltile or tafle, to be fure, but nothing new; for novelty is only a name for an old effect or appearance revived with a little alteration Of Pattern Drawing. alteration, and (making a metaphyseal excurfion) if the queflion were afked, what is original > an anfwer could not be eafily obtained fufficient to fatisfy fome enquirers ; the term having no pre- cife meaning, till it is agreed on all fides, how ideas are acquired, whether intuitively or by (en- fation, or, in other words, whether product- ions termed original,are or are not but mere copies of certain archetypes, conveyed to the mind by its attendant faculties : and if the proudeft de- figner in the printing c* any other bufinefs, would be candid, he would confefs there is not near fo much of invention in what he produces, as he defires the world to give him credit for; fince if traced to the fource it will generally appear that the mind received a hint, if not fomething more expremve, from fome vifible object or other ; and it may further be faid, that the greateft, genius would be afhamed to be discovered at the little fhifts he often makes to attain a certain end, by fearching into nooks and corners, as it •were, for objects to flrike out fomething from, or at the quantity or collection of fubjedrs he fecretly heaps up to fupplyhirafelf with thoughts •and hints, and the methods he takes to disfigure the ideas he thus more or lefs furreptitioufly purloins, to make them appear novel ; and too glaring Of Pattern Drawing* glaring it is, how a reputed genius will contend about his claim to what is palpably plagiarifm ; and which among Defigners in the Callico- printing mifinefs, is certainly as frequent as among other claffes : Befides, if it be confidered what a number of Defigners are always at work, and how many thoufand patterns are produced in a year, but how few of them remarkable for novelty, it mutt feem ftill more clearly there is very little of ftrikirtg out of the beaten paths and much lefs of originality than might be expected. In fome cafes it is more difficult to imitate than invent ; for the quality generally demand- ed in an imitation, is to excel the original; but unhappily that word excel, in this cafe, is very vague ; it may very likely be altered for the better, if alluding to its being rendered eaficr to work ; but almoft every different perfon will have a different idea about its appearing better, or having a better effect, at leaft as far as they chufe to fpeak, or are at liberty fo to do. As Of Pattern Drawing* As applicable to the preceding fentiments, it is obferved that fome will fay,when a Defigner means to produce fomething remarkably excellent,he firft fixes on a plan in his own mind, and nearly forms it there before he, transfers it to paper ; all this the man of fancy fmiles at, knowing its fallacy ; for whatever may be faid of the mind forming a plan of fomething, the judgment regulating it, and thus mentally working on it till compleat, it is ftrange that any perfon is infatuated enough to believe fuch a thing, or ridiculous enough to afTert it can be done ; the works of the greateft genius's that have been produced, no matter of what fpecies, have been perfected but gradually, and as it were by piece-meal, but to advance the pofition juft mentioned, isjuft as if a perfon faid, I have an original in my mind, and 1 will fet down and copy it on paper ;--- he may to be fure let about it, but the original in his mind will be very far from being faithfully co; ied ; for he may begin as the ideas prefent, themfelves, but by being obliged to disjoint that mental original, he very foon in his progrefs lofes the firft ap- pearance, and before the completion of his copy 5 through repeated alterations, reje&ions, &c» it may very probably be quite of a different ihape and complexion ; and that this is the cafe in § § Pattern- H Of 'Pattern drawing.

It is time now to turn from thefe excurfions, and proceed to give fome hints (Rules they can- not be called, nor are they infrted as fuch) reipe&ing the operative parts of defigning, more to evince a readinefs to do thofe fome fervice who perhaps expect: it, and are not to be per- fuaded but that it may be obtained in fuch a manner, than from any confidence in their value, or fatisfaction in their difplay ; as, in refpect to utility or practice, they can only be general documents, from the changeablenefs of ftile or tafte ; befides, every perfon who is in a fituation to decide, and can have his decifion put in prac- tice, has his fixed ideas of tafte, propriety, good drawing, &c. fome through prejudice, fome through affectation, and others through oppo- fition.

Hand ards of elegance, propriety or grace ; all fee through different mediums, and of courfe are differently affected. * N. B. Refpedting the following hints, it may- be noticed, that feveral of the Rules for putting - on fhould be kept in fight by the Defigner,---efpecially about the width of the cloth,— an even face,--eafmefs of pencilling,-* ceconomy in cutting, &c.

Rule a number of lines, as you can beft make out, from the pattern, according to the diftance the objects ft and from each other, as Fig. 5, which done, place an object in every other fnuare, as fig. 6, that is, one at the top of a fquare, another near the middle, another near the fide, and fo on, thus will you be certain of the objects having a regular appearance in the general difpo- fition of them, and at the fame time Handing promifcuouily. 6. In order to afcertain on the paper on which you make your Iketch or tracing, the joinings of trails as well as of fprigs that are irregularly dif- pofed whether clofely or widely fituated, make ufe of this method. After you have made your fketch or tracing, repeat, either on feparate papers, or on one large enough for the purpofe, as much as is neceflary to fhew the joinings at the head and fides, in or- der to fupply that which is defective or remove whatever may be improper ; having done this, hold it flopingly from your fight, and look at the whole from top to bottom, from fide to fide, and from corner to corner, to fee that no lights nor heavy lines nor bodies of objects appear, and as there is generally in trails what may be called the main ftalk, fee that it branches out regularly from fide to fide, fo that one fide balances the Rukiy &c, for putting on. other, and that the branchings fo run into eacii other that it may feem to flow regularly all over, and to be ftillmore certain of its even difpofition, hold it with the back towards you betwixt your- felf and the light, that by feeing it reverfed you may know if it lean more to one fide than the other. 7. In fmall patterns it cannot be amifs to put en the halves or quarters exadtly alike, according to the nature of the pattern, |j taking care that the halves or quarters are not to be diflinguimed,, in the repetition of them, for the conveniency of one block anfwering for the grounding of each part after it comes off the grafs whether the pattern was intended to be fo grounded or not ; for which purpofe, as rubbing oft' is the lean: certain method, an oiled paper, or a drawing from a itenfil is to be preferred, and a ftenfil feems beft, becaufe, as it is only a part of the pattern that is affected by the grafs grounds : except when compofed only of plain fet objects.

This leads to the obfervation that a Printer mould not let a fprig, or principal flower, or other object get off the edge one fide or the other ; for in the cafe of fprigs, &c. {landing wide apart, he may try, at leafl, on cloth of any width, if he can preferve them whole without leaving too broad an edging on either fide. 9. A pattern with fix fprigs or commanding ob- jects {landing as fig. 9, cannot join whole or in halves, but rauft drop or rife one third as fig. 10, or the objects will not be at proper diflances in the joinings, but then, of courfe, the pitches mull be made to anfwer in the fame manner.

In tranfverfe patterns, that is, in patterns in which the trail lines or objects run acrofs from corner to corner, the way as reprefented by fig. ii, whether in {tripes or all over, let the tranf- verfe difpofition appear on the cloth the way as fliewn fig. 12. as it will thwart the right hand difpofition of the parts of a pattern generally obferved in drawing, and the aptitude weufuallyhave to look from the left to the right; as the light is from the left, and the hand in drawing naturally tends that way, otherwife we mould be always incommoded by the ihade ot it. ii. The ftraiter the work is of the fide or near the edge j the better it is, as there will he the fewer gaps, and the necemty will be obviated of having (whatthePrinters call) a lift to make up the defi- ciency, and lefs will be cut to wafte in the making of it up. This rule, however, mould not be fo ftric*t.ly adhered to as to make the joinings too nice, by cutting flraight through every thing, or particu- larly through a number of objects ; for the more they can be preferred intire, the lefs injury is done to the pattern, as the print being pitched too Rules, &c. for putting on. Too high or too low, or too clofe or flack, renders them all unfhapeable ; it is likewife better to keep them whole "en account of the grounds, efpecially the grafs ones, as they by being dis- jointed mull: add to the bad fhape of the objects; but, as it may happen that the breaking of the objects is of little confequence from their fhape or fituation, or that the ground-w©rk may be of more confequence to preferve; the above obfer- vation mufc be regulated by attending to what are the characteriftic parts of the pattern, or what firft catches the iight, and thefe mufl fuffer the leaft poffible injury, whatever may be the fate of the fubordinate parts. 1 2. If fome part of the pattern be coarfe or have a body, it will not allow the fine parts to be fo •clofe or fo fine as they otherwife might be, as the quantity of colour requifite to fupply the folid parts will choak up thofe that are clofe, or caufe thofe to work coarfely that are fine ; and here it may again be obferved, that though neat drawing on is to be commended, yet, if not drawn fufficiently open or clear, where for inftance, there may be fhades or fhapes as fig. 13, 14, and 15,* though cut by the bell cutter, and may appear tolerably Rules, &c. for putting on, tolerably open and fair on the block, they will not appear fo in the impreflion, to fay no- thing how they may fuffer from a bad cutter or printer, or from being printed on coarfe cloth, or when half worked out ; for a print ftiould be cal- culated to work decently when a certain quan- tity of work generally expected to be executed by one is nearly compleated, and therefore (to give forne inflances) in drawing or cutting fhades as fig. 1 6, 17, it is not advifeable to put them on in that manner, however graceful they may aprear on the block or even in the cutting, becaufe the colour will hang in the corners and give the work a clumfy appearance, hence to cut them with lefs of a curve as fig. 1 8, 1 9, they will,by working clearer and neater, amply compenfate for fuch a deviation. 13. Avoid, if you can, having any part of a clofe trail as in fig. 20, at the head of a print, as the prefTure from the pitching of the print will render it coarfer than any other part of the trail : the prefTure however may pombly be prevented by the pitch pins ftanding out farther than com- mon from the work : for which preventative fee the rules for making pitches. When Rules, &c.for putting on. 14. When you have fhades, as fig. 21, or parti- cularly lights Handing or running with the grain as fig. 22, 23, be careful to have them cut fufficiently open, otherwife you will be deceived by their working clofer than intended ; for when a print gets moift,the opening clofes confiderably, and what may have appeared open in putting on, or when cut,' will be choaked up in the printing, efpecially if cut with a thick knife, or if not fufficiently cleared at the bottom and fides.— See more refpecting this article in Rule 6, for cutting. 15. In joinings either at the head or fide, the more a ftalk or trail joins in this upright direction fig. 24, the better it is for working, inflead of joining fig. 25, as the bell Printer cannot at all times, on account of the varying of the cloth, keep the joinings fo well in command at the fide as he can at the head. 16. In drawing leaves or fharp-angled obje&s that are to be pencilled, it is recommended to terminate them as fig. 26, 27, or fig. 28, infteadoffig. 29, 30, 31, as fuch a finifh will keep the penciling, particularly the blue colour, «on account bf its thicknefs, from being run into C the Rules &f . for putting ot; a the white, or the ground; for without fuch a filling up of the ends, the pencillers will either leave a light at the corners, as fig. 31, or, in en- deavouring to fill them up, they will be apt, from the largenefs of their pencils, to come over the line, as fig. 32, and the fame obfervation will hold good reipe&mg every other place where the pencilling goes into corners or angles.* Note, In calculating the expence of pencilling, and thereby fixing what quantity Jhoulcl be in a Pattern, a certain number e/Jlrokcs or dafhes, which a Penciller is fuppofed to make in a Jlated time, is worth a certain price. 17. In putting on the block, nothing is more deceptive than having to leave lights in dark grounds; for if any.fhape is drawn fig. 33, you may be deceived when the ground is filled up, as it takes in the line you have drawn, and makes the light within-fide appear lefs ; it is ftill more deceiving if you have to draw the boundage as fig. 34, as its thicknefs gives the whole objea a larger appearance than it really has. Here it may be noticed (though touched on before) in putting on * An imperfeftton of this kind runs nearly all through the work of one of the firft Printers about town.—This, with fimilar obfervations will be en- larged o»> in the progrefs of this work.

In drawing on grounds thathave large bodies « fig. 39, that are to work in thin colour, .faci- ally if they fraud wide apart, remember thai they wiJl in the working, from tie fink ngbr fpread- ing of the colour, and its adherence to the Ides, make larger impreffions than the furface of the cutting ctherwife would; hence they fhouid be proportioned to that circumftan'ce, and put on perhaps fmaller than they are in the pattern. And as the pale colours worked with fuch folids, will be loft, or appear much paler when imprefTed from fine lines or pins if on the fame block ; therefore in fuch cafes feparate ■C Z grounds Rules, tjc.for putting »». grounds fliould be had for the fine parts or for the pins. Under this head would be confidered the drawing on blotch grounds, and the other grounds that fall into boundages, but as the cutting far- ther or lefs into the boundage is partly regulated by the thicknefs of it ; no precife dire&ion can be given, as every one knows the circumftance to be attended to, in this cafe, is to prevent any light edges from appearing either within or with- out the boundage.— See more to this purpose Rule 7, under the article Cutting. 1 9 . Wherever there are to be pins, mark them on the block previous to its going into the Cutter's hands, that the wood be not chiuellcd away, and where the pins touch or join the cutting, mark them accurately, and give intimation to the Cutter, that the ends of the fhades or ftalks may be cut downright, otherwife a difagreeable gap Willie left, as fig. 43 ; and in afcertainin S the fizes of pins, be aware that as the wood gets coarfe by working, the pins fink in, from the repeated blows at the back ; and if worked in colour that has any corrofive quality in it, they ' foon get finer ; hence if provifion is not made .for thefe circumflances, the impreflion of the WOOd Ritlcs, &e, for putting tn. wood and pins will irr a little time be very dif- proportioned. It is likewife needful to inform the Cutter of what quality the pins are to be, that the depth of the chiflellihg may be regulated accordingly. 20. In ruling Bengals the following mode is recommended, in order to make the ends join each other, (provided the block has not been too much warped, or any particular accident happened.) Make on a flip of thick paper,or rather thin lead, with which tea-chefls are lined, as many divifions as you have Bengals to put on, then fixing it to the fquare line at one end, prick through the divifions on the paper, and transfer them to the block, the finer the pricked holes the better ; . having done this, remove the flip carefully to, the fquare line at the other end, taking care that the two extreme holes anfwer to the corners of the fquare, and prick through the fame divifions as you did before; then rule as ufual from the pricked marks, thus will each end of your fquare be a correct copy of the other; but as the ends of Bengals are of moft. confequeace to preferve, it may not be amifs with a lharp thin blade, to cut a little into the wood at each end. C 3 21. If Rules, &c. for putting on, ai. K it be a joined block that you life, take care that the joint comes between the Bengals, and as a preventative againft the confluences of a print with Bengals warping under the Cutter's hands, it may be neceffary to let one end of the Bengals be cut thicker than the other ;. fee fig. 44, and make the ends join by cutting away from the broad ones, when the print goes to work ; or whenever Bengals do not pitch to themfelves, that is, when they join by pitch- pins, it may be ufeful to cut both ends, as fig. 45, and in the joining let the points run into each other, as you thereby prevent the [difagrecable appearance that the jundion has when two fquare ends join badly, as fig. 46, but in the other inftance, at the worft, they will appear as fig. 47, which is confiderably better. 22. When you have a number of fet objeas, fuch as rofettes, rings, leaves, &c. to put on, it being very difficult, if not impoffible, to trace or draw them alike in the ufual way, it is beft to have the objeds cut accurately, and imprefled or. printed on the block, which if you can do clear enough ■i Rules, &c.for pitting otu- .enough to cut from, it will fave much time and labour; or if you cannot do it fo fmartly as you wifli, make a mixture of lamp black and Hake white, fo as to be about the hue of black lead, the paler the colour the better, and let there be little, if any, gum in it; fpread this pretty thinly on a piece of foft leather, and fo take off your impreffions on the block, which. «ione, draw over the objects, lo printed, with well-tempered carmine (fome add gum bogia) and when fmlfhed clear away as much as you can of the colour you printed on, with a piece of ftale bread; for if you ufe India rubber, it will change any colour which has gum bogia in it, to a very dark and dirty one. Another method is by printing your object on paper with a proper mixture of carmine and trea- cle, which a little practice will afcertain, and then rub it off from the paper on to the block ; the advantage of which mode is, that the colour does not fpeedily dry, fo that you may take what time you pleafe in rubbing it on ; but the neateil method is by the object being engraved, and then taken off on paper, either by hand or a prefs, in the red oil colour that is ufed in the printing Rules, isle/or -putting on. printing on paper ; which not fpecdily drying any more than the treacle colour, it may be rubbed on the fame manner. Other methods of a fimllar kind for another purpofe, are propofed further on. 23. If for any particular purpofe you want to fix your colour on the wood, a thin white tranfpa- rent varnifh will fee u re it ; or if you ufe a black lead pencil only, flrew fome powdered rofin all over, and then move a hot iron about at a little diftance over it, by which method the rofin will liquidate and forma kind of varnifh over it ; or what is ftill more fimple, if you only draw your tongue wet with faliva, over a black lead drawing, and let it dry, the black lead cannot be eafily removed. 24. When you have a pattern to put on, con- fining of very fmali objecls, very clofely and promifcuoufly fituatcd, an eligible way to prefcrve an even face, is to take a fmall portion of the fquare of the block (in fome cafes half ah inch will do) and fee how many objects will go in it, "and then repeat this portion on another paper, to what fize you pleafe ; varying the difpofition. of the obje&s as much as the pattern will admit, in order to prevent the appearance of a repetition. Note, Small clofe patterns will well bear enlarging a little, elfetn the cloth they appear Jmalkr and clofe*. Rules > &c.for putting on* 25. As circles, rofettes, and other common ob- jects, are always in ufe, it would not be amifs to have punches of different forts and fizes, to ufe occafionally on paper or blocks, particularly where the objects are on dark grounds, as fig. 48, or have a thick boundage, as fig. 49, as the ob- ject impreffed on the wood will be vifible s to cut or g* uge from ; or if the impreffions fuffer from damping, they may be drawn over in red, and thus from their accuracy much trouble would be faved ; cr if you want a folid object repeated, accurately, it may be managed by ftenfelling it, that is, by an object as fig. .50, cut out of a piece of oil-fkin, a piece of thick paper rubbed over with bees wax, or a piece of thin fheet lead, and then lay the colour on with a pad, or in what other manner you find convenient; or if yoa want to do fomething like fig. 51, it may be managed by cutting out the object nearly all round, as fig. 52, leaving juft joining enough to prevent the inner piece from falling out, the impreffion of courfe will be imperfect as fig.' 53, which imperfe&ion mufl be made good by the pencil. 26.

As fometimes on emergency things cannot be got on too foon, you may, after having put on the print, trace the fame accurately with a firm oiled paper, and then retrace it on another block, or at leaft thofe parts that the ground which you mean to put on, falls into, or joins; on which accordingly draw your grounds ; but ftric"t charge muft be given to the cutter that he does not deviate in the leaft from the drawing. The advantage of this mode is evident, in having the principal grounds ready as foon as the print; and if they do not exactly fit,' perhaps a little alteration may make them ; and that is bet- ter than fetting fome prints to work before the grounds are cut, as then whatever is amifs in the impremon of the print, muft remain fo. It is however fuggefted concerning this article and the preceding one, that they mould only be nfe.d in cafes of abfolute ncceffity, as their neat- nefs and accuracy cannot be much infifted on. In fact, every one muft grant that any opera- tion, efpecially where contrivance is neceffary, and has to go through many hands, if exe- cuted with precipitancy, cannot reafonably be expected to be free from fome fault or other ; and in this inftance it moft undoubtedly is ic- quifite, that, withr very few exceptions, prints and grounds fhould be adjufted to each other be- fore they go to work. i KM —«•» Rules, i^c. for putting on. 27. In finishing the joinings of fome certain prints it will do no harm, to let the ends of ftalks or obje£ls, that join at the heads and fides, be a little too long, it being an eafy matter to pare or cut away what is fuperfluous ; or fometimes if particular parts of a joining are fuffered to remain rather longer than might feem needful, as fig. 54 ; they prevent the appearance of a break in the ftalk, fee fig. 55, 56, 57, if the print is flackly joined. 28. Avoid fo difpofing of a leaf, a flower, or feveral ftalks at the corners of a print, as to require four joinings to bring them together, fee fig. 58, 59, 60, but, if ppflible, let the corners of the fquare fall in fome open or blank . part of the pattern, as the joinings are lefs. likely to be perfea at the corners than any where elfe. The above rule, it may be obierved, chiefly refpe&s patterns where the work is clofe, or the. objeas fmall ; as in loofe patterns, or where the C 6 objefts Rules, &c* for putting en. obje&s are large, and light of work, it may not be of much conference where the .joinings are made.

In joinings it is perhaps be ft not to give much latitude to Printers, as it thereby makes. fome of them more careful in the joining, and rarely fatisfy them howjhe grafs grounds fall % \ for if they know they may run their joinings a. little, they will be. apt to over-run that latitude;. It is however neceffary to- inform them what work is to be grounded, that they may be.accor- dingly cartful in pulling over their pieces, and. folding themfmoothly and even. The Foreman of a fhop Jhould be informed of the defign of every fat tern. 29. Inftead of the common way of making cut die joinings, by rubbing off from black lead, or by an oiled paper, the following mode is offered where particular nicety is required, at leaft it muff be fomething more certain, from tbe circumftance of one fide and end being cut, than the ufual mode, as there is always a pro- bability of the Cutter deviating from the draw- ing, or the marking out of the joinings. e" After Rules, &c» for putting en.

In prints with fprigs that Hand wide apart, or in very loofe trails, if it can be done without hurting the ground, a few pins placect between, and filed nearly to a point, and rather below the furface of the wood, will keep the cloth down ; and caufe the work to appear neater, by pre- venting the edges of the objects prefTing too much on the cloth ; it likewife anfwers the pur- pofe of keeping the fubilance of the block nearly equal, as otherwife a deal of wood mufl be hand- tooled out ; and the hollows that remain muft weaken the block, and render it more apt to warp, or perhaps fplit, if the print requires much knocking. In grounds where the parts Hand far i each other, it can be done very conveni- ently, by letting thefe (what may be called) guard Rules, t3c*jor putting ««• guard pins, full into parts of the impreffioh of the print. It is granted that an objection lies againft this obfervation, as the points of pins Handing at great diftances from each other, are apt to make holes in the fieve, or in the cloth, efpecially where coarfe or too much blanketing is ufed on the table; and if one thread of the piece is broken, it will in the procefs of copper or field-work be- come a hole ; therefore forne caution is needful in this cafe to place the pins, not too far from the work, efpecially round the outfule of it, fo that the circumftance alluded to be prevented; .31. Where a print or ground is put on with- out any drawing, fuch as rings, bengals, that are executed with dividers, tracers, &c. fo that only an indenting is made in the wood, if a thin mixture of colour be fpread all over, and the block afterwards fcraped with a fine edge, fome of the colour will remain in the indenting* or hollows, and be tolerably vifible ; befides, by purfuing this method, if the wood be damped, and the indentings fwelled up, there will ftill be nMl mtm Rules, &c.for putting on. be fome guide to the Cutter ; in fliort, it will ' have nearly the fame effect as oiling, the wood where a curf line is cut. 32. In drawing for pinning, be aware that though in the drawing, your lines may appear to nanddiftina as fig. 61, 62, 65, yet the print when pinned will not have that appearance, the certain vacancy between the pins deftroying it, as the pins will appear as %. 64, 65, 66. Obferve the fame in drawing lights in bodies of pins, as fig. 67, for though the object may appear tolera- bly fhapeable, while only as a line, yet it will be deftroyed when enclofed in pins as fig. 68, there- fore in fuch cafes, let there be a proper openefs •bferved or provided for. 33, In drawing pinwork for cylinders, recollect that there will be fome difference between the width of the furface of the pins, and the bottom of them which in rings, rofettes, &c. will be of fome conference, Of Pitches. t N the nrft place it can never do any inj ury alway 3 to have fquai es cut at the corners, and oftentimes in the middle, both of ends and fides, the ne- cemty of which the nature of the pattern will determine ; but at any rate (as above faid) they are needful at the corners, as they determine when you join the print by them, whether the pitch -pins are on the fquare or not; and that you may the better join the print by the fquares, let the fhape of them be as fig. 69, or rather as fig. 70, to hinder the clogging of the colour in the corners, unlefs the fituation of the work hinders their being fo cut, and let them ftand out as far at leafr as the pitch-pins; becaufe in the firft trial of the joinings (fuppofing the fquares are cut as they mould be) the print may be joined by them, as the pins may be then adjufled, if not put in right, or if moved by any accident. If it were not for the conveniency of joining by the fquares, inflead of the fhape above recom- mendedjit would be belt, to cut them as at fig. 7 1 ; Of PITCHES. 71 ; but however, when they are cut as fig* JZ (for as fig. 73 they never ftiould, though too commonly done fo, as the impreffion gives no certain ftiape) they ftiould not be drawn on the ruled line, .as the ruling will perhaps mifguide the cutting of them ; and if the fquares are left for the purpofe of ruling grounds from, they ftiould be drawn within the fquare line. 2. At the head the pitches mould . ftand out from the work near one quarter of an inch, that the wood may not prefs on the cloth in pitching the head of the print, and of courfe appear heavier than the reft of the worko. The firft pin at the head mould be at leaf! one quarter of an inch within the fquare line of the near fide, for fear of the near edge running on the table ; the fecond pin, for the convenience of the off-edge printing, mould be regulated ac- cording to the width of the print, and of the cloth it is likely to work on ; for if the width of the print is fuch, that the edging is lefs than half that width ; which by the way is a bad circumftance for the face of the print (as obferved already) there is no occafion for a middle pitch, either Of PITCHES. either for print or grounds ; and the fewer pins for pitches is always the better ; for if the firft pitch ftiould get off the near edge, the Printer, for the fake of the grounding, muft get on again if he even makes a cut : as for the third or off pin, it is little matter how near* the off-fquare it is, fo it does not ftand out beyond the line of the work on the off-edge, as it then would be particularly liable to accidents. 3. As the pitches of the print, from their outward fituation, are in danger of being re- moved or otherwife injured, it mould be a rule to put flout pieces of wire deep in the wood, rather flanting, and leflen the tops with a 'file or other inftrument ; and in cafe the print mould run on the table, it would not be amifs, efpe- cially if it be a ciofe one, to put pins at the off-edge, unlefs the mape of the work will an- fwer the purpofe, to fall into certain places, in order to fill up the vacancy, if there be any of confequence, at the near edge. Likewife for fear the print mould come off the hear edge, and of courfe the fide pitches for the grounds be rendered ufelefs + 0/ p i r CHE Si oielefs : let there be a pin at the bottom of the ground to fall into the work, if it can be fo ma- naged, at the. bottom of the print. 4-, The firft fide pitch fhouldbe abotlt half an inch- down the fide, the other as near the bottom as con- venient, and if it can be done, let them pitch* into objects fo that they be little feen, taking care however that the joining of the print does not obfcure them, Side-pitches need not be out farther than juft to be clear of the work ; in or^er to. prevent a light edging. 5. The pitches for the print being afcertained* put in the pitches for the grounds which work next in fucceffion; thefe muft be diftincl: from the pitches of the print, and be clear . when the print is joined ; one pin towards the. bottom of the near fide is fufficient for the ground, taking care to place it below rhe fide pitch of the print, that it may not hinder the printer from feeing his print pitch ; this however is not neoeiTary to be parti- cular about when the ground pitch is placed within . Of PITCHES. within the work : Endeavour likewife at all times to make one pitch or a fhape do for as many- grounds as you can, obferving however, that a ground that works to another ground ought not to pitch to the print. 6. If the work is to be grounded after it comes off the grafs (as you can make no alteration then) be particularly careful that the pitches for thofe grounds be not obfcured by any means, and if you .can place them where pale colour only will cover them, it will be the better, as that will partly hide them ; and let them be but juft large enough to be feen, which rule indeed fliould be carefully obferved in refpect. to pitches in general, or if > large pins are put in, the tops fhould be leffened. 7. To be more certain of having your pitch pins • in their proper places, they had better be put in before prints or grounds are given to be cut (un- lefs you have no doubt of the carefulnefs of th. cutter, in that refpe&) and before your prints or fome Of P I T C H E S. . fome certain grounds go out, be fure to rub off parts of the drawing on paper,making a memoran- dum what parts you rub them from, as they will be checks againft the cutter in proving whether he has or has not deviated from the drawing, and probably prevent a deal of altercation, when the work is done ; or, as a further caution,* the whole face joinings and all may be procured, by damping a flout piece of paper, laying it on the furface and gently rubbing the back, till you have a flight counterpart of the drawing ; and a very flight one will be fufEcient to fhew the trail, or the fhape and fituation of flowers, and other objects. A Putter-on * For if a Cutter has a pique againft the Drawer, or bears ill-will to the matter, or if only through wantonnefs he may alter the joinings, the direction of a ftalk, or fhape of an object, or in grounds, he may cut out of fhape, or move an object out of its place {for fuch things have been done) and then, without feme check, what can the Putter-on fay in excufe, or how clear hiwifelf. Of PITCHES. A Putter on, and indeed any other perfon, is likewife here advifed for his own fake, to make minutes of what may have been matter of opi- nion or contention between ]?is employer and himfelf about the mode of performing any thing when his employer or other principal has it done his way, and have thofe minutes ready to produce ; if, in confequence of fuch deter- mination, the cffedl happens not to be as it fhould, or if the performance is not fuccefsful in other refpects. As well as advifinga Putter-on to be guarded again ft the Cutter, the writer advifes the Cutter to be on his guard, and that is, to fee the rub- bing-off performed, and that his employer keeps one in his poffeffion, or elfe demand one for him- felf, otherwife it is poflible the putter-on in his way, may do a Cutter an injury, by altering the rubbing off in fome mode or other, and thus make it appear as if the Cutter had not attended to the drawing, or other particulars^, Of Squaring Blocks. IN making a fquare (as it is always called) though the four fides are feldom equil, if a print is intended to be a 5 overoa 5-4th cloth, or about 7" 3-8ths wide, it fhould not be above nine inches long, it being handier for working, and not fo apt to warp, as if longer in proportion to that width, and for very clofe fine prints that are difficult to join, the fmaller they are the better, as they have lefs cutting, are eafier to work, the warping is not of fuch confequence, and the grounds are more likely to be hit in, efpecially the grafs grounds, and the beft general fize for them is about 8 by 6 and a quarter, or 6 and a half at the utmofl, or what is called a fix over, for to make it any thing wider under 7 3~8ths, fo much cutting would be thrown away ; as it would ftill be fix over, and the worfe for it, it then having to work a narrow edging on the off fide, the inconvenience of which has been amply dlicuiled. D 2. For Of Squaring B LOCKS. 2. For larger prints it is prefumed the beft general fizes are, for 4 overs about 12 by 9 and a half, for 3 overs 15 or 15 and a half by 13, but when a pattern requires a pair of prints or more, the length and width muft be governed by the nature of the defign ; if not drawn to any particular fize, unlefs the pattern would not be injured by altering it. Note, In fpeaking here of 5 overs and 6 overs it muft be underftood (as before remarked) as re- ferring to ell-wide cloths ; though after all, (as likewife remarked) the beft rule to abide by, is knowing what cloth is moft likely to be made ufe of for the respective patterns that are deter- mined on. The lizes however as above will nearly fuit narrows, with one more over. This circumftance of determining on the fize* of prints, is of confequence from other motives ; for to have a print unnecefTarily fmall (which is the cafe if the work be light and eafy to join) is protracting the working of it, and encreafmg the expence attending its working, if on account of its fmallnefs, the Printer requires a proporti- onable price ; befides, fuch a print will be as much worn in doing a hundred pieces as, if made a little larger, it would be in doing twenty .or thirty more ; which altogetlrer is of fome im- portance, Of Squaring BLO-CK'S. TjorUnce, and mu'ft considerably outweigh the circumftance of its having coft lefs for cutting, if that had been an inducement to have had it cut fo fmall. It is however as neceflary to confider what it may have to do in refpe& to grounding, par- ticularly grafs-work ; hence if the fize is fuch that the grounds cannot be worked whole, the print in this cafe had better have been fmaller,. and this circumftance is determinable by the eafe or difficulty of the grounding, for if the grounds are to fall into fmall objects or fine lines, the print mould be fmall, or if it be larger the grounds mutt work in halves, unlefs there is good latitude for the grounds to fall, and then they may work whole with fuch a print. 3, In fquaring a block the moft. expeditious and certain method, as well as of making the divifions, (if they are required) is to have a plate of copper or pewter, fet out with a number of Fquares within each other, of the different fizes above - mentioned for 6-overs, 5-overs, and 4-oveis, as being moft generally in ufe ; and fet into as many divifions as youchufe, and at the D2 corne s Of Squaring BLOCKS, corners of each fquare, and wherever the divifions are marked, let there be holes pierced through, as fine and as ftrait as poflible ; you have then only to lay your plate on a block or paper, and with a fine needle prick through the holes where neceflary, and then rule as ufual from the pricked holes left on. 4. Another method is, by having a piece of thin wood or metal, made angular as fig. 74* which laying on a block or paper, rule two lines fig. 75, and then with your compafTcs or dividers (beam compafTes fig. 76 are befi) extended to the length of your print, fix one point at A, and make with the other a hole or curve at B, then put one point on the line as far diftant from A, as, near as you can judge, what the width of •your print is, and ftrike a curve as as D, this done, rule a line from the bottom of the curve to B, fig. 77, then move your dividers to the width of your print, put one point at A, and ftrike a curve as at F, and with the point at B, make another curve, interfe&ing that at D ; laftly, rule from the interfeclion to F, fig. 78, and you have your fquare. But Of Squaring BLOCKS. But obferve, that the truth of your fquari in this manner, depends on the juft form of the two fides, from which you firft rule, and of the inftrument which you ufe. This inftnament, or the copper or pewter plate firft fpoken of, if it be cut perfectly on the fquare, will ferve to try whether pitches ftand fquare or not, bv laying it to one of the ends and one of the fidfs at the fame time, and repeating the trial at the other end and fide. 5. If you fquare your block in the ufual way, and have occafion to make divifions, divide into halves firft ; then divide thofe halves ; then divide thofe quarters, and fo on ; inftead of taking a certain part, and running the dividers along the line, becaufe of the great probability that the fame number of divifions run along in the fame manner, will not form the fame length exactly again. 6. In fquaring a block for a ftripe pattern, if k be on a joined face, take care that the joint is parallel to the fide of the fquare, and (if it can * be Of Squaring BLOC KS. be fo) in the moft vacant place : to get it parallel N to the fquare line, you have only to put one point of your eompafles on the joint at one end of the block, and with the other make a hole or curve near the edge of die block, from which, you mean toraife your fquare ; repeat the fame at the other end, and from the two pricked holes or curves, rule the line which is to be that from, which you raife the fquare. This obfervation Ihould be attended to in fprig patterns, or any other where the joint can be pofiibly avoided. \ Of Cutting. a Sa Drawer, or Putter-on, fhould ftudy how "^ to preferve the effect of a pattern before he- puts it on, a Cutter fhould endeavour to pre- ferve the effect intended ; and if he has the in- tereft of his employer in view, as well as his own, he will examine as far as his judgment lies, where it is defective, or any way improper, and not, as is too generally the cafe, think only of contriving how to make the charge as high as he can, (if the price be not agreed on before-hand) to fuch it may be hinted, they are ultimately not gainers, for it may be expected every employer will think firft of thofe who think of his intereft as well as their own immediate emolument. From what is above fuggefted, a Cutter is not to infer that he is at liberty to alter the drawing or deviate from it as he pleafes, befides, he fhould be very cautious in that refpe&, as he may not be aware what counterparts or checks are kept againft him. A Cutter likewife fhould confider when he takes any work whether he can do it well, if the putting on, or more properly the drawing, be indifferent, becaufe if he does not execute it to- lerably and alledges in excufe, it was badly drawn: It is the more inexcufable in him, as undertaking to execute whit he knew he could not do as it fliould be; as among other reafons, it muff go to Of c u T I A G. work bad as it may be (unlefs it be too bad) from the impoflibility of its being put on and cut over again in proper time. But much worfe it mufl be in him who will proceed on his work, though it -is evident to him, that from fome miftake in inaccuracy, the article muft be ufelefs to all intents. * As a general obfervation refpe&ing cutting, be it noted that the principle of found and graceful cutting (if the term may be allowed) depends on properly forming the knife, and having a good command of it ; as for the fhifts of pinking, and other expeditious modes made ufe of as fubftitutes for cutting, the face, from being forced or mat- tered by fuch modes, rarely works clean or (lands well ; and by thofe who require found cutting, the ufe of fuch modes mould be exploded, as more proper for carving; but in cutting for callico- printing (it is repeated) the knife, and that alone, can make a proper face, where JTrcngth and neat- nefs is required to be combined. •Sorry the Writer is to fay that either through pique to the drawer, enmity to the matter, or from that wretched groveling principle of fuch mifchances multiplying work, he has known it to be the cafe, and lie is not backward to own in cafes where he has blundered, or not been fufficiently accurate (for he don't pretend to infallibility though he prefumes to publifh this work) he has experienced inftances of fuch a kind. II Rules for Cutting, i. A careful Cutter will at firft look at the joinings and meafure and compare the difhnces of the pitch pins, and if the pitch pins are only marked, he will be careful to put them in as foon as poflible, as the deferring of it till the marks are fo faint, that they are almoft put in by guefs, is productive of much trouble, for even the common practice of drilling or goudging for them, chifTeling the wood away, and then driv- ing in the pins is deceptive, the tops of the pins frequently not being where they ought to be. If however the Cutter puts in the pitch pins he mould not chifTel the wood away till the reft of the print is finifhed, or if it is cut at home the wood fhould not be cleared away ti I it is taken to fhop or fome other proper place, as they might be removed even in carrying thither. • 2. Le* Of C U T T I K G.. 2. Let the difference between tlie furface and: bottom of the work be jufr. fo much as will ferve as a foundation for it, as every cutter mould be aware, that if thicker, the print will work the coarfer, even if the furface be fine, and the firft time it is pumiced it will work very clumfily; as for the care of preferving a face, every tyro in cutting muft know that is of the firft concern, and of courfe the cutting of it away in any part, or leaving fo little foundation that it is liable to be injured by the fsnalleft accident, is the greateft dilcredit to a profeffed Cutter that can be. 3. Next to a proper foundation and an even face, a found print is one where the work is not cut through, at the joinings of branches or fhades fee fig. 79, for where the knife goes thro' thofe joinings, efpecially if if be a thick one, or the wood very damp, it will eafily be feen, after the print has been ibxaetimc at work/ and lays in a warm Of CUTTING. warm or dry place ; but as in fome inflances it is impoflible to cut in that manner, proper attention fhould be bcftovved on thofe parts that are left without the fupport alluded to, that they have a firm foundation, otherwife the uighteft accident . will remove thtm. 4. Where pins are marked to touch the furface of the wood as fig 80, cut accordingly, that is, down right acrofs the end, or it will be the caufe of much trouble both in drawing for the pinning and in the pinning itfelf, from the pins not being able to ftand upright, nor join with the furface of the wood J but will leave difagreeable gaps as fig. 81, between the impreffion of the wood and pins ; and if the pins are marked to ftand near a line as fig. 82, carefully cut more upright than in general on the iide the pins are to be, and cut deep or fhallow according to the fize of them., 5. Where pins are marked and have no cutting near them, leave fome wood for th& file to reft ©n.v f„ Ii Of C U T C I N G. 6. If you have to cut a curf as fig. $3, cut outfide the line as drawn (unlefs the putter on has provided for the circumftance) otherwife the line of pins cannot be where they were intended, for the drawing being the line that the pins is to Hand in, if you cut the curf through that draw- ing, it is evident the pinning muft be within fide of that line, becaufe of the wood, as fig. 84. In cutting lights w"th the grain, be cautious to cut with a thin knife, and rather flanting, whether you chiffel away or not, or when the work is damp the wood will clofein fome degree, and of courfe appear in the impreflion not fo open as thole lights which are cut acrofs the grain, tho in the cutting they were full as open. Itfecms to the Writer, that in cutting fine lights with the grain, it is not the heft way to cut downright of eacH fide, and chhTel away at the bottom, particularly if the wood be very dry or fcarcely damp when cut, as the furface will nearly dole when the wood gets damp, but rather to cut very deeply and take the wood out with the knife, for each Tide rifing flopingly from the bottom, the chance of the two edges of the fur- face Of C U T ' T I N c. face meeting together is not fo great ; but as a counter-balance, the colour is more apt to gather than when cleared at the bottom with the chiffel, therefore if cutflantingly andchifTeled away with a very fmall tool, that inconvenience will be pre- vented. 7. Cutters are not fometimes aware how much they injure a block by extreme partial damping or letting it lay a long time on damp ftones or bricks, efpecially if one end is kept damper than the other a long while, as the face is liable to come up in places by damping or wetting while there is nothing but the glue to hold it ; and as blocks are fometimes badly venered, or may have Iain long in improper places, or may have fuffered by a removal from a damp place to a warm one- and the contrary, there is the greater realbn for a Cutter to be cautious in that refpect, hence it would not be amifs as a Cutter clears away, or as foon as finiflied, if he fecured the face by a few brads. Note, The Writer purpofely inferts the follow- ing article, though properly belonging to putting on, in order to lead a Cutter to look a little further than the point of his knife. 8. If Of CUTTING. 8. If you have to cut from an imprcmon always be informed whether the cutring is to be within the line, on it, or without it. as this circumstance is very often a mere matter of opinion, though at other times determinable by particular circum- fiances. Sec Rule 18 for putting on. And, In pafte grounds that have to hit to ob- jects furrounded with ftormont, or other clofe or folid ground, it is needful to cut within the line, for it is better the ground ftiould come into the object than not come up to it, as that will fliew a difagreeable run of white outflde the line ; but if the object: is only to have loofe ground work round it, it would be better to fecure the filling up of the object : it is only fuggefted in that cafe to be better within than without, making fome. allowance for the fpreading of the colour. Again, if there be large and fmall bodies to work together in the fame ground, as fig. 85, cut the fmall bodies rather more within the line than if they flood alone, as the quantity of co- lour neceffary to be carried by the large ones and the blow requisite to imprefs them, would other- wife caufe the fmall ones to fpread over the line. See Rules 12 and 18 for putting on, where there are fimilar obferYations refpecting both prints and ounds. Of CUTTING. Note, In f peaking of cutting, it may be ob- ferved to thofe who prefer the ufeful to the fuper- ficial, that as what is required of a print or ground, is its being able to make a proper impref- lion, and for a proper length of time, all that is done which does not tend to that point is delay- ing its going to work, of courfe, all that delica- cy and formality in the fubordinate parts of hand- tooling, chhTeling, &c. which fome affect, can only give a print or ground a good appearance, but does not enhance its intrific value in point of utility ; as every one knows that the clearnefs and foundnefs of the cutting in refpect to the face, is the efTential quality that is defired; hence longer time bellowed in thofe particulars, more than fufHciently clearing the fupernuous wood away, is, befide delaying the working of it (as above-faid) rendering it unnecefTarily expenfive to the proprietor.* The Writer cannot fupprefs the infertion of a word or two, as a hint to fome Mailers (though copioufly difcufied with fimilar matters in the eflay • It is fuppofed the Writer will not be thanked by many Cutters for this obfervation, but as he occafion- ally makes free with Mailers (as the following ^ob- fervation evinces, as well as many others, which will appear at the clofe of this publication, as likewife where he makes as free even with himfelf ) he truft 8 " ?hey mult acquit him of partiality hi what he advances ****. Of C U T T I N G, efTay toward the conclufion of this work) that they donot always get their cutting done fo cheap as they imagine, when they prefs a man down to a low price, for a Cutter who is a matter of his bufmefs has a mode of working, not eafily dete&ed when he brings his work home, according to the price bargained for, or what he expects for it from his knowledge of his employer in that particular ; cfpecially if he knows his employers judgment of. cutting is not very extenfive. As there is a wide difference between being,, impofed on, and getting work done for much lefs than it is worth, the writer juft hints here at the impolicy of fome, who when they get work done very cheap, (no matter through what motive it is fo done) cannot be fo far contented, but will fpeak of it, and will perhaps fay who the perfon was, in order to induce others to do the fame; the confequence may be a combination not to. work for fuch a perfon ; and any how it renders fuch a man unwilling to do work very cheap again : after hinting at impolicy on one fide, it is proper to hint to Cutters, that it is equally impolitic to make a boaft (particularly a public one) how expeditioufly they can work, what ex- cellent and peculiar inftruments they ufc, how well paid they have been, &c. when this is. the cafe, can it be much wondered that matters fo often doubt the integrity of their workmen, re- fpecting the value they fet on their performances ; Of Pinning. BEFORE you begin pinning a~ block, efpeci- ally if it is to be pretty full, a few brads* drove in, in the vacant places or indeed a!) that are neceflary, is very proper to be done, in order to fecure the veneer from rifing or removing, and if the pinning be very clofe or covering, take care that brads are firft put in, punched down, and pegs put over them, i. A block that has many pins to be put into it particularly if it is not a fmall one, jfhould be hollow in proportion to the fize and quantity of the pins, and fhould be in a dry ftate, for pins acting as wedges even in a degree when bored for, they naturally tend to throw a block round ;■ hence if a block that has a great many pins, and particu- larly if they be large ones,happens to be very round when began to be pinned, the confequence pen- haps would be its being rendered ufelefs, from the extreme round ftate into which it would then be thrown. This Of PINNING. This inconvenience may poflibly be prevented in fome degree where the back, or a crofs back is but weak, by having a ftrong temporary back firmly. fixed on. 2. It is ufual for Pinners in pinning of blocks to begin at one end and work gradually on to the other, whether the pinning is full or not, but perhaps it would be more advifeable to do a little at one end, then a little at the othei, then a little in the middle, and fill up or finifh in the fame progreffive manner ; as, befides the chance of avoiding the partial warping of the block, you are more certain, by doing thus, of preferving an even face of pinning ; for it fometimes hap- pens that pinning is fuller at one end than the other, or different in other refpe&s, from being finifhed in a hurry, or put into another perfon's hands, and the liko ; which would probably be avoided, by purfuing the method above recom- mended, or fomething fimilar to it. 3. Where large andfmall pins are toftand toge- ther, it is in general neceflajy to put in the large ones tuft, efpecially if they be confiderably fo, as by taking up the moil room you will the better judge where to put in the fmall ones, and fmall ones can be theeafier fet to them.

The quicker pins are put in, the firmer they hold; and the more uniformly upright they are put in, the evener they work ; for if put in very flaming, the fetting of them upright afterwards, loofens them at the bottom ; and confequently in the courfe of working, they will be eafily re* moved, as well as by other common accidents.. 5. If you have a number of large pins to put in,. avoid (if the pattern will admit) two or more- flandihg near each other exadly in a line with the grain, efpecially if not bored for, from the great chance of their fplitring the. face, by ftand, ing in fuch a direction. 6. If you have a flower, or leaf, or other object,, as fig. 86, begin at the points, and then fill up the line as regularly as you can, that is, in re- fpea to the diftances of the pins from each other: Ifthemapebe like fig. 87, begin at the points, and then fill up the line. If Of PINNING, 7. If you have branchings, fprays, curls, &c.as fig. 88, 89, and 90, take care of the line or ftalk from which the others run or branch out, as thefe fhould be kept in as perfect a line as you can, keeping however the angles in view, that the corners may be open in making the lefler. branches.

If you have fmall curve lines, as fig. 91, do not put a pin in the middle, as %. 92, but rather put two, as fig. 93, otherwife it will have an angular appearance, efpecially if the pins be large. 9. Where pins are required to be placed near the cutting as fig. 94, the fhade of the wood will frequently deceive the pinner, refpe&ing the dis- tance to be obferved in placing the pins ; in order to guard againft this circumftance, frequently look at the block with the face held direaiy a* gainit the light.

If you file the pins without the wood being wetted or fwelled, do not file them even with the wood ; elfe in a very little time they will be too low ; as exclnfive of the wood fwelling by working, the repeated blows of the Printer at the back of the block, draw the pins further in, exclufive likewife of the pins wearing away, cfpecially when worked in colour in which iron liquor is ufed.

In bradding prints and grounds, drive the brads different ways, that they may have the firmer hold ; a few brads well difpofed of is better than a great many, as they act as wedges in the back, even if the veneer is drilled or bored through, and of courfe tend to throw fome blocks round the fame as pins would, as the boring for the brads muft not be fo deep as the brads are long, they then having no hold of the wood ; and remember, in prints or grounds that have backs of deal, or other flight wood ; longer brads -than common are requifite; otherwife, from the Toftnefs of the wood, or opennefs of the grain, they will be of little fervice. 13. Take care that brads do not ftand in lines clofe together with the grain, as the more dia- mond wife they ftand, the better they hold ; and confequently a lefs number will do ; nei- ther is there fuch a chance of the face being fplit. Care mouid likewife be taken that brads are not put on a joint; it is however neceflary where there is a joint, to put more brads about it than elfewhere, as well as round the edge. It Of PINNING.

T)REVIOU5 to what theWriter has to advance •*■ on the management of blocks, a word or two addrefted to Block-makers cannot be deemed unneceffary, as their inattention in general (if hot entirely) to what he obferves below, has rendered many prints and grounds of no ufe ; while the fault has been attributed tocaufes very remote from the real ones. Therefore, if Block- makers wifh for the credit of making firm Handing or good working blocks, they mould be careful, that, in the firft inftance, the faces and backs are free from cracks and {hi vers, and not tending to a decayed ftateno more than being too green, and that of crofled backs the backs are alike in age, texture and feafoning; indeed they mould be cut not only from the fame plank, but from the fame part of the plank, elfe the refiftance of one to the other cannot be 1 reciprocal, and confequently the very purpofe for which two backs are joined to- gether is directly deflroyed; See the obfcrvatlon refpe cling crofs-backed blocks further on* E Block- Of BLO CKMJKING. Block-makers fhould likewife take care that in joined faces, the pieces of the face be of the fame part of the plank, as a joined face that has one fide clear, hard, or ftrait grained, and the other foft, beachy, curly or knotty, is hardly fit for any purpofe ; the bad being unfit to go with the good, which is only proper for nice work, and the good part is thrown away if the whole block be ufedfor fomething coarfe, or of little import- ance ; and even a whole - faced one had better not be fo, unlefs the whole face is of the fame quality all over; therefore two or more indifferent pieces of veneer had better be put together, as ferving for fomething that is coarfe, and the fame of two good pieces for a contrary purpofe. Further, if one fide of a piece of veneer that is broad enough for a whole face is bad and the other fide good, the face had better be parted than put on a back whole, it being then in the fame predicament as a joined face, that has one piece good and the other indifferent ; in fhort, a blockmaker had better burn his very indifferent wood, than fend it out, unlefs avowedly fent home as fuch, and as fuch ordered, as oaly fit fqr common purpofes ; otherwife fending a num- ber of blocks of the above defcription, gives room to f Of BL OCKMAKIN G. to fuppofe he has not a fufficient quantity of good wood by him, or is too ignorant or negligent of his bufinefs, or elfe incapable of attending it fo as to dojuftice to the orders he may receive.

The writer is aware that in fome of the in- flances juft mentioned, much muft be left to journeymen, who, too often, are not very foli- citous about their matter's intereft, or reputation. This however does not (with every perfon) ac- quit the mafter of his refponfibility ; he is applied to, and of courfe looked to for a proper perform- ance of the orders. It may therefore be obferved, as a hint ta Blockmakers, or their men, that among the caufes of blocks not Handing well, may be their taking part of a plank for a back that has a tendancy to warp one way, and a piece of veneer with a ten- E 2 dancy Of B LOCK MAKING. dancy to warp the other, and glueing them to- gether in fuch a ftate.

Note, It may be here obferved, that good printing depends a great deal on the manner in which cloth (as the phrafe is) is got up* ; but particularly, how it is calendered ; and in the cafe of cloth having to be grounded after it comes off the grafs, too much attention cannot be be- flowed on the means to render the performance eafy and expeditious ; in attaining which, the grand object is to get the cloth as near as poflible to the flate in which it was printed on the table ; to which fta e the nearer it can be brought, it need not be laid that the execution of * If cloth is calendered too wet, flove drying will take the calendering out ; and if one edge is wetter than the other, then after flove-drying one edge muft run flacker than the other, or if the calender itfelf is imperfect, and the cloth naturally flimfy, Printers will accordingly complain ; but, fuch incon- venience may be partly removed, by running the pieces through a liquid of a ftiffening quality.

Of Printing. PReparatory to what the writer has to obferve^ concerning the operation of printing, a word or two of general import cannot be ^inapplicable, and probably to fome Printers not unacceptable. In the riril: place, it is obferved, that it is a very common faying among printers, and even held as a maxim by many, " that no perfon is fit to give directions to Printers, or occafionally point out any thing as faulty, or, in other wonfc? to overlook that branch of the bufinefs, unlefs he is, or has been a Printer himfelf." The Writer will not fet about in a formal manner to oppofe the maxim; becaufe it feems to him, from what he has gathered by an attendance to that department, to be founded on a very re- rtricTive principle, limply this, that printers in ge- neral, conclude or appiehend, a perfon who is not a Printer, does not lay the necerTary flrefs upon their Of PRINTING. their being properly accommodated with every requisite, in refpe6t to colour, fieves, flate of their piece, &c. &c. &c. and therefore cannot fee the inconvenience, which, in fomeinftance or another they labour under, when fuch a perfon ventures to point to any part of their work as not being properly executed ; he will only fay, that many who make that a maxim, don't con- sider, that a mere printer, is but a little more competent to that Situation than a common iieldman ; for unlefs he has a general judgment of whatever has any relation to printing(andthat includes fome knowledge of the other branches tinder fome fyftematical arrangement) he is not fo proper to fupcrintend as another, who poffefles fuch a portion of judgment, although he never had a print in his hand; as fuch a one is more able to guard againft bad work (unlefs from the allowed incapacity of the workman) and more able to remedy it when it occurs. But with thofe requifites it is neverthelefs an advantage to him who has to overlook Printers in being or having been a Printer. In fact the writer apprehends, too many of thofe who hold that maxim, do not clearly know when every appendage is in proper condition, or when Of PRINTING. wlien really fo how to keep them in that ftate; hence they are foon at a lofs in one inflance or another, and when found fault with, quickly get more confufed ; and then, not knowing how to extricate themfelves; lay the fault on any thing rather than their own inability or want of judgment ; for unlefs their ideas go along with the methods pointed out to them how to remedy the fault, they are as much in the dark when left to themfelves, as they were at firft, if not much more embarraffed. The writer can however fay, he has often feen the futility of fuch excufes, by a Printer of approved abilities, ex- ecuting with apparent eafe, under a fimilarity of circumftances, what another could not make work with fit to be feen. Reverting immediately to the maxim above fpoken of, the writer trufls, a Printer will however grant, if he has every accommodation he requires, that a perfon who is not a Printer may at leaft know when the work does not appear as it ihould, and may venture to fay how it ihould be ; and this leads to remark on another common phrafe of Printers, when under certain circumftances fome fault is found with their work reflecting the joinings, which is " that they keep to the pins." F 4 Now, ■Hte Of P R IN TING. Now, however ftrange it may feem to fome Printers, the writer afferts that the pitch-pins are not his proper and infallible guides ; for every Printer finds at t^nes, that through the twift of the cloth, the warping of his print, a miftake in pitching, and many other caufes, the pins only ftrve as mere directions or guides, to whereabout he is to lay his print : in fhort, joining a print and joining the pitches are different things ; the fame as pitching a ground by a pin or two, or by pitching the fhape of it to the work of the print, Therefore a Printer ought always to keep in his eye or his mind, how the print fhould join fup- pofing he had no pins to pitch by, for what will become of his printing when he lofes his joinings, if he has no other mode of determining him than the pins? and even in joining by the pins, his fight fhould take in the whole top and fide of the print, and he mould confider and know how the work is to fall, otherwife he cannot work to a certainty in refpect to the joinings, or getting into them, when by any caufe whatever he is thrown out; It rauft be obferved however, that in this, as well as in every other rule, for any operation whatever, Of PRINTING. whatever, it is impoffible to provide for every circumftance, fo in this cafe it is allowed that fome prints, from the nature of their conflrucYion,. fuch as very promifcuous or irregularly fliaped ones, feem to have nothing to direct the Printer but the pins ; but even in this cafe, exclufivs of the pitch pins, there is an attention due to keeping the face at the joinings as even, or as- much alike the reft of the imprefllon as poflible,, which will not be the cafe if the work be too : clofe, or flack at the joinings. Further, it may be advanced tlxat in thefe" .inflances, lightly as fome printers may think of Grounders, they may be looked to as examples for their imitation, as they rarely regard pins, fo much as the fhape of the work, efpecially in grafs grounds ; and that implies a neceflity of ftudying (if it may be fo faid) what the nature of. the pattern. is; for even when pins may an- fwer, they generally have their grounds lighted all round; not looking jull at this or that corner, but (as every printer ought) they employ their fight and attention on the whole length of the ends and fides.. After faying thus much, which the Writer begs every journeyman printer not to take as arrogantly advanced, but only as fuggeltions for hira< Of PRINTING. him to confider of, and turn to his own advan_ tage, he proceeds to fpeak immediately to the operative part. When a Printer takes a new print in hand,* his firft care is to try on paper, or a trial piece, that it is in the fquare, the pitches firm in their places, that the print does not want mending, and that it is neither too round nor too narrow ; likewife that his apparatus is in proper order; or if he cannot have it fo, he fhould intimate to the proper perfon in what particulars it is not fo; and the order in which his apparatus ought to be • As well as the above confiderations, a Printer may reflect that the expence incurred by cutting the print he takes in hand, with the additional one of his working it, muft be re-imburfed before any profit can accrue to his employer : therefore, as all that depends on his management, he is in a more momentous fituation than many think : as all the expence incurred, and the profit reafonably expect- ed, will be loft if through his incapacity or inatten- tion, he fpoils what he is entruiled to execute, or fuffers his prints or grounds to get any way fo out of order, that little, if any,ufe can be made of them, by himfelf or any other perfonv Of PRINTING. be, no Printer fhould need to be informed, is, that Ills blanket is not too nappy nor too hard, too thick nor too thin, his fieve too fine nor too coarfe, and that his piece is properly calendered or flowed. * Thefe matters adjufted, the tearing is the next object, and not the leaft important ; for good printing cannot be performed without good tear- ing ; and good tearing can only be fuch, when a proper and equal quantity of colour is difpofed over the fieve. In * Some may expeft perhaps that it be fpecified here in what inftances thefe matters are to be at- tended to. The writer certainly attempted it, but found from various caufes, fuch as the cuftoms of a particular fhop, the caprice of an overlooker, dif- ferent courfes of work at different mops, &c. he could not do it to his fatisfaclion : it may however be here faid, that fome perfon fhould be informed of what the defign of every pattern fhould be, for - much, refpe&ing fieves, colour, flrength or flight- nefs of the impreffion, &c. depends on that circum- stance: Indeed (as before obferved) the putter-on : need in raoft cafes confult a proper perfon in the Printi ng-fhop* Of PRINTING, In the circumftance of trying the joinings, a Printer may be deceived fometimes, though the pitches of the print all feem to anfwer, and the pitch pins of a ground anfwer to the pins or holes in the print ; for both thefe cafes may occur, and yet the print not join, nor the grounds fit* (as intimated a little before,) hence if his judgment be not fufficicnt to difcover the defign of -the pattern, in refpetf: to the trail, or the difpofition offetobjeas, or in what manner the grounds mould fall, he fliould confult thofe who may be fuppofed to know. He fliould like- wife, for the convenience of thofe who have to ground after him, fee that the pitches be clear,, though they fhould be but barely fo (as obferved in the article refpe&ing pitches) and that he keeps his ?

As a Printer is anfwerable in a degree for his; print or grounds keeping in order while he is working them, he fliould carefully obferve their; tendency to get round or hollow, and mould fre- quently examine whether any parts are brpken or, worn more than the reft ; in either of which cafes,, he mould give proper notice : for if a print gets very round in the courfe of working a few pieces,, it mnft ftand to reafon the grounds can only fit a, part of them, unlefs they mould chance to fol- low the tendency of the print, or can be eafily warped to fuch a ffcate ; but, as there can be no- certainty of that, the work fliould be Hopped, and the print gently brought to a proper ftate; for every Printer mu ft know, that when (through caufes, obvious enough) he continues working a pnnt till it is fb much twifted, that he cannot poffibly proceed ; violent methods are made ufe of, and the print rarely afterwards is capable of doing tolerable work. A Printer, befides being attentive to thofe par- ticulars immediately under his own eye, is ac- countable Of PRINTING. countable for the ignorance or neglect of his tearer, for as a carelefs tearer may very foon do irremidiable mifchief to a print, in warning and drying it, and likewife, by not properly cleaning fieves, and brufhes, may do the work much in- jury ; a Printer, if he is not every whit as care- lefs, will fee in what manner they are done : in- deed it would be well, from the many accidents that happen from prints, and other matters being left to the care of tearers, who are in general ig- norant boys or girls, that it had been an efta- blifhed cuftom for the Printer himfelf to do, at leaft, part of thefe offices. Befides the above hints immediately addrefled to the Printer, as what he fhould always have in his view, the greateft part, if not all, that has been obferved, and may be farther fpo- ken of, refpec"ting cloth, colour, blocks, and prints and grounds, ihould come under a Prin- ters confideration*; for unlefs he can account, in fome • See the not*, refpcfting the needfulnefs of a Printer's referring to the rules for putting - on, cutting, &c. at the conckifion of this fection on printing.

HJII As nothing that is faulty is too trivial to guard againft, or to animadvert on,* the writer will clofe this article on printing with mentioning two or three instances of inattention in that department. The Writer once obferving, that about one of the corners of every print that was laid, the impreflion was heavier! ; in pointing it out he could he can the better know how to manage them ; and if he be acquainted with cutting, he knows a found piece ot work from an unfound one, and will, (or at leait ought fo to do) ufe it accordingly. * This may ferve as an apology for the infertiou of thofe obfervations, which may probably to fome perlom, feem of too little conference to be remarked on, mm Of PRINTING. could get no other reply but that the print worked fuller there than any other part ; this, however, from the appearance of the face, he would not grant, the Printer ftill infixing it was fo, 'till at lair, looking obliquely on the fieve, as the tearer worked, he faw a ridge of colour left nearly in one place, after the laft ftroke,. which the tearer could not rectify ; at length, looking at the brum, it was plain that one part, by fome means, had been burnt fo confiderably, that the hairs were fo fhortened and thinned, that' that part hardly touched the fieve ; and from her method of holding it, a ridge of colour was. always left, that caufed the effect above mention- ed : nowhere was a triple inftance of inattention; in the firft place, the tearer had careleflly fuffered the brufh to be burnt in drying h y (as Hie afterwards owned, and probably fear of being reprimanded, induced her to keep it fecret) in the next place me did not perceive the effect it had on the fieve ; and laftly the Printer, if he perceived the effect on the table, did not, as he fhould have done, fee that his apparatus (which included the tearing brufh) was, or was not in proper order. Another time the writer feeing the head of the ini- preflion in general fuller than the reft, he of courfe mentioned it ; but here the fault could not bedif- coYtred Of PRINTING. covered to be in the tearing, nor did it appear to be in the face of the print, and the Printer was fure it was not his fault ; for he dipped and turned his print, and then dipped again (the print re- quiring much colour) but at laft, he was con- vinced it was from his knocking it, and yet per- haps he not to blame; for in the middle of the back that was let in, there was a very hard knot, and the other part toward the head re- markably foft ; fo that by infenfible degrees the knot had at length, by its refiftance to the blow of the maul, caufed it to Aide as it were into the foft part, where it had evidently made a cavity ; and the Printer as infenfibly giving into that direction of the maul, at length, inftead of hitting the back in the middle, hit it nearer the head, which made the impreflion heavieftin that part. Another having a fprig print to work, either mi flaking the pitch end, or chufing that for the pitch that feemed moil: commodious for him (for the pitches were pins pitching to pins) he nnifhed what was allotted him to do in that manner, and the miftake was not feen till the work was to be grounded ; the confequence was, that the perfon who had to ground it, was obliged either to begin at the other end of the piece, or to have a fet of aukward pitches pnt in to anfwer the work the- ' Of PRINTING. the way it was printed ; either way however was an k ward, the fide-pitches being off the edge, and particularly fo, (from circumftances which cannot be well defcribed) for the grafs grounds which likewife belonged to it. In this inftance the Printer was in fault, in not concerning him* felf about how the grounds were to fall ; or in fa& it feemed as if he did not note whether any grounds belonged to it, much lefs to take care, as every Printer ftiould, that they were all clear, and diftincl from each other, as before repeatedly intimated. Another circumftance was obferved, in a Printer working a pattern of fprigs, that flood 6 or 7 in- ches apart, by making it a point to work the near fprigs clofe to the near edge ; by this it happened that the off-edge divided a fprig, fo that but half of it was on the fprig ; now the inconvenience here that efcaped the Printer's notice or confide- ration, was, that in making up a garment, either half a fprig muft frequently appear, or two or three inches of the cloth muft be cut to wafte ; and the pencilling, of courfe, thrown away, but in this circumftance to prevent or remedy that inconvenience, the Printer had only to work the near fprig an inch or two further in the piece, which trom the great diftance of the iprigs from each other was of little confec|uence ; and then Of PRINTING. the fprig that was half off of the off-edge, would have been entirely fo. Thus the garment could not be made up with- out either imperfect fprigs, or without cutting towafte; now in this cafe it may be obferved, there wanted an attention to the remote!! cir- cumftance, that of the wear, or at leaft, the making up of the garment j and this includes a query, which might with propriety have been pat to that Printer, which is, If he had been printing that piece as a prefent for a favourite femal©, whether he would not have beftowed a little more consideration on the particular al- luded to. Other inftances to the above purpofe could be adduced; it is, however, trufted, by exhibiting thefe few, that every Printer understands he is requeued to confider himfelf under a neceffity of attending to many more circumftances than at the firft glance may feem neceflary, or even as apparently bearing no relation to hjs allotted department. And in proof of what the writer has advanced on the neceflity of Printers (as well as others) looking to other departments than their own, if Of PRINTING, if a Printer refer to Rules I, 3, 8, II, 14, l^* 13, 28, for putting-on ; Rule 7, for cutting; and Rule 3, for pitches ; as well as fome others, that need not be particularized, he will find articles enough to obferve* From looking back to Rule 8, refpe&ing the keeping of fprigs whole, it feems proper to ob- ferve, that a Printer fhould take care if they drop or rife in the joining, that he carry one di- rection through the piece, becaufe if they go one way only half over the table, and half the other, the confequence will be, that the difpo- fition of the fprigs (unlefs they are all alike and are to ftand one way) will appear as fig. 97 ; for inftance, fuppofe fix fprigs ftand in the print as fig. 98, of courfe they muft rife or drop a third to make the joining ; now if the pattern be compoled of two forts of iprigs, {landing thus, %• 99 anc ^ 10 °> one ^ ort ^ 10U ^ run acf ofs the piece ; but if the dropping or riling is checked in the middle, (becaufe the Printer finds a little inconvenience in the joining,- from fuch a cir- "cumftance) they will appear thus in the middle of the piece, or in fome Other part, fig. 101, that is, three fprigs of the fame fort will be together* This may be probably over-looked in printing, but when the whole piece is feen extended over a roil, it will ibon catch the fight. Of Pencilling* THE Writer thinks little if any thing can be faid of this operation, it being fimply filling a line with colour, except in cafes where pencillers have to form fhades or fhapes; of this it may be obferved, and fomething more may be faid in another place, that fome attempts to be fure have lately been made, to make fomething like Drawers of them, by giving them only lines of pins, or others narks, as fig. 102, as a guide ; but how accurately they ad- here to fuch directions, or form a fhape as it ought to be, every obferver muft form a decifion. . In foreign patterns, it is known a deal of work is done by the pencil, but why not prac- tifeable here, the writer will not (at prefent) fay any thing further than, that there feems to him to be a line, beyond which, in this cafe, as well Of PENCILLING. well as in others, it is abfurd to attempt goinjr beyond ;~the bell Pencil ler (fuch as we have in this country) can go but a little way in making ihapes of any kind, without fome boundary • of courfc (as above obferved) refpeding their pen- cilling to a line of pins, as well as their making fhadesin flowers, or other objects, it feldom does much credit to the defigner, in the imitation of his defign, which they fo roughly and inaccu- rately make on the cloth, efpecially when the colour is of * deep hue ; in other cafes where a mere flam is perhaps only wanted, they may execute what the writer otherwife explodes, as here the pins, or whatever elfe it may be which they pencil to, catches the fight and takes off the attention from the inaccuracy or bad fhape of the pencilling. See fomething refpeding pencilling Rule ,6 and 35 for putting on. Of Engraving. WHAT has been before faid of the putter-on, and the Cutter well consider- ing how to attain the effect that is defired, fhould likewife be attended to by the Engraver ; for before the pattern is begun, all impediments towards producing the defired effe&, fhould be removed; hence the Engraver himfelf fhould ftart all the objections that he can difcover to- wards that end, and if reafonable, they will jene£t. credit on his probity and judgment, as otherwife he might to be fure engrave it, and engrave it well ; and yet the plate may not be able to do work properly in every refpecT ; but, (as before obferved) if all impedimerts are pro- vided againft, no one need be told there is the greater certainty of the fuccefs of the operation ; befides, if miftakes happen (and happen they will to the moft careful) they will be excufeable in proportion to the pains taken to prevent them; therefore Of ENGRAVING. therefore, that Engraver has the greater! merit, who can beft engage for the effect his engraving will have on the cloth through its whole procefs, and can accordingly manage his work for that purpofe, as well as being merely able to cut a clear ftroke, or being an expeditious workman ; and particularly, his value is enhanced if he be well acquainted with the mechanifm of the copper-plate prefs, and the operation of working it; in fhort, whatever may be faid of an En- graver's good fight, fteady hand, neat touches, clean ftrokes, and fo on, it is the appearance which his work has on the cloth when finiihed (unlefs ill-managed at the prefs) that marks his judgment, and makes his labour valuable. It may be obferved, that as every Engraver has his peculiar modes of operation (fimilar to what has been faid of Cutters and Pinners) therefore fuggeiiSons towards directing them muft in many cafes be unneceffary ; though here an Eng aver is not circumftanced as a Cutter, a Pinner, or Printer, engraving being an operation that ftands alone, excepting its being fo far connected with block-printing, that the Engraver by making his obfervations on it, may fee wherein be can imitate or Of E NG RAVING. or excell it in any fhape, and if he will look carefully over the Rules for putting on the Mock, and even for cutting, he will find many of them which may be made ufeful to himfelf. For initance, Rule 2 points to the neceffity of well cpnfidering how to transfer the effedt of the pat- tern from the paper to the cloth ; Rule 4 points to the confideration of what are the moft finking features of a pattern. Rule 6 directs the atten- tion to the prefervation of an even face ; Rule 10 is often necefFary to attend to ; and Rule 17 parti- cularly fo, if he has any thing to do with dark ground plates. Rule 23 may probably be ufefui in refpecl: to two or three colour plate-work. Rule 24 may be made ufeful in an inverted man- ner, that is, by taking care to keep ftalks, or whatever elfc is to join, rather too fhort than too long ; as it is eafier to lengthen when they may be rather too fliort, than to fhorten when they are too long. In fome cafes where the flalks have to join to dark objects, the Rule may be of ufe as it literally itands. In fhort, as one principle inculcated through this work, is, that expanded obfervation will form the bafis of judgment ; the end of which is to attain certain points ; an Engraver, by keeping that principle G in Of ENGRAVING. in Iws view, may be able to educe fome advan- tage from articles apparently very remote from his immediate department, and a flrefs is the ra- ther laid on it here, becaufe it is fometimes faid, a perfon may be a good Engraver without being able to draw well ; but, not to draw well, in its general acceptation, includes a great deal, and perhaps more than is abfolutely needful for an engraver to Callico- Printing to know, it is however, infifted on, that unlefs an Engraver or Copper puncher* ftudy in what effect confifls, as taking in tafte, fpirit, exprefilon, &c. he cannot tell how to enfure it, much lefs produce it, if left to himfclf, or if his copy or pattern be not. well managed: it may be true, there have appeared in- stances of good Engravers producing good effect, and yet not able to draw ; but to this it may be faid, they mull have had naturally the principles within them of drawing, though they have never operatively evinced it; and had fuch perfon s ap- plied themfelves to craving inftead of engraving, it is probable they would have mevvn it; but how- ever, th?s for certain will be granted, that an En- graver can hardly be the worfe for being able to draw, and therefore to contend about the necef- fity or utility of it to an Engraver, or that a man can • For this operation there is no fixed term, therefore if the above be an aukward one, it is begged to be excufed, as the writer «mnot find a better.

Immediately refpecting the following rules, the writer intimates, that he purpofely omits faying much of real engraving (treatifes enough being published concerning it) as what he chiefly ad- verts to can hardly be called engraving; yet even in the prefent mechanical mode of procefs, it feems very often neceflary to adhere to the principle of engraving as adopted for Callico- Printing*, that is, in keeping three fhades in view, for in the fmalleft modern patterns that are chiefly performed by punching, the keeping of thofe three fhades muft be attended to*, as in G 2 the * In the Hiftory of Callico Printing at the clofe of this work, fee what is faid on the introduction of Engraving into the bufinefs, its progrefs, and the innovations it has undergone till this time. * Stri&ly fpeaking, the- white cannot be a fhade, but propriety muft give way to arbitrary terms. = If - Of ENGRAVING. the firft inftancc a light muft be enfured, then a ihade (which is belt executed by diagonal lines) and then a folid; now in well proportioning thefc three articles, which conftitures, in general, the good appearance of this kind of patterns, it is necefTary to be very careful (as obferved above) that the white objeft, or whatever it is that is to appear white, rifes up or ftands forward as it were, as in general that it is which gives a fpirit to the whole; then to obferve that the ftrokes forming what may be called a fhade, be not fo open as to caufe acoarfe appearance on the cloth, or fo clofe as that the impremon of them will form a mafs : And lafHy, That the folid part be juft fufficient to give (according to the nature of the pattern) a proper weight, or finifh to the whole. is here faid too, that this circumfrancemuit be atten- ded to in the firft in/lance ; — that is, rn the drawing of the pattern, hence this obiervation, and perhaps others, may ieem more properly belonging to the defigner, but it is the rather inierted here to induce Engravers (as well as the Writer has endeavoured to induce Printers and Cutters) to look a little farther than to their immediate departments.

In refpect to punches, the firft circumfiance to attend to is, whether the impreflions they are to make, or parts of an imprcflion, are to ftand alone or to have fine, coarfe or folid work that is done with the graver, join to them ; for, excepting fome cafes, as perhaps where a ftrong outline may be required to a flight or faint filling, the impiemon made by the punch and the ftrength of the engra- ving fhould be proportioned, as in the inflance of dark grounds ; for in this cafe, if the outlines of the punch be fharp and fine, the impreflion that it will make in the copper will be much fooner worn out than the ground, the engraving for a dark ground being generally very ftrong and deep. 8.

There being always more or lefs trouble in the trial of every new plate, on account of the joinings, the fixing the plate to the Aider, &c. it is recommended to the proprietor or wor- ker of everv prefs, the following expedient for the preventing of fuch an inconvenience, fimilar to what is offered for fquaring blocks. "When you have a plate that exactly accords to that part of the roller as intended, whether a quarter plate, on a half quarter one, or both ; and it Rules j l^c.for Engraving. it is likewife exactly cut on the fid' s for the pur- pofe of being fcrewed or otherways fixed to the Uider, let there be made at the four corners of the fquare of it, and in as many intermediate divifions as can be made convenient, fine ho^s drilled through it, as ftraight as poffible; then, whenever another plate is to be made ufe of, that and the plate which has the drilled holes, are to be laid face to face, and with a fine needle prick through the drilled holes in the plate that lays uppermoft to the plate that is beneath (taking great care that neither of the plates be removed) and at the fame time, as carefully mark, accord- ing to the notches already cut in the fides of the uppermoft plate, where they are to be cut in the other ; thus will the fquare of every plate (intended to work at the fame prefs) be alike, without the Engraver having the trouble (as is ufually the cafe) of fquaring every plate, to fay nothing of the chance of a miftake; and thus likewife will every plate be adjuftcd to the prefs with as little inconvenience.

The Writer now concludes (at leaft for the prefent) his fuggeftions on Defigning, Putting- on, Cutting, Printing, and Engraving, with again enforcing what he recommended at the beginning, and has feveral times repeated (though probably to fome the repetition may be tirefome) that in every part of the operation, the fucceflive ftages, and the appearance of the work as for fale, mould be kept in view ; and that every drawer, cutter and printer, mould confider the operation under his hands, fo conneaed with, or dependant on each others refpeftive branches, that unlefs attended to in that light, the laft ftate cannot exhibit an appearance which is undoubt- edly defned, or even an appearance that will do credit to any part of the operation ; as an im- perfeaion in one part only, muft diminim the value of the whole ; and is the more to be re- gretted (at leaft in the writer's opinion) if pro- ceeding from the circumftance of one perfon having, fomehow or other, got his work out of his hands, without being able or willing to con- fider what other operations it has to go through, or in what manner it may be affeaed by them ; and therefore, as every one muft allow it is better to Rules, &c. in Ho prevent faults, than having to remove them, the writer has endeavoured to be as particular as poflible in the fubjeft of putting on the block ; as the more attentively that operation is per- formed, in adapting it to the circumftances that are to follow, the after-proceffes are more likely tofucceed.* As for exquifitc neatnefs of drawing, (except in particular cafes) the writer does not lay fo much ftrefs on it as many do; he himfelf feldom affected it ;-j~ it has its merits undoubt- edly ; but (as fpoken of in the beginning of this work) it only has it, ftriaiy fpeaking, when united "* See the inti-odu&ion to putting on, mewing the neceffity of an operation being accommodated with true and other conveniences. t As to putting on the block, the Writer owns he never very much defired to have any thing to do with it, not from thinking it beneath him, but from a thorough conviction of the difficulties and other difagreeable ciraunftances attending it, together with the great probability that after the^utmoitcare, the effect at lait, from caules which cannot be always forcfeen, would not be as intended.

TJAVING treated of the operations carried J- A on within-doors, the writer now proceeds to his Suggestions on thofe executed in the Copper houfe, and its appurtenances ; or, as it is ufually termed, the work without-doors ; in which ' though not precifely proper fo to arrange it, he mall include Colourmaking, (i) from its affinity to Copper-work and Fielding ; but in treating of thefe departments, where he addrefTes himfelf to the Workmen generally employed in them, he i s aware of having to encounter prejudices of the worfl kind ; for, to fpeak freely in this cafe, as H well (i) Colour-making- in fome refpecls maybe cc, fidered as among the firft procefles,or at leaft previous to printing (as obferved elfewhere) but,as there may be occafion to introduce various confiderations with it, that, by their length, would rather break in upon what is exhibited as a feries of mechanical procerus, it will be fpoken.of in a feparate feftion further on. Of Copper-Work, Fielding, &c. well as he has hitherto done, (2) the generality of coppermen, and head fieldmen, and he will add, colourmakers, may be deemed as little ?c- quainted with the principles of their refpe-.dve branches, or indeed of being able to confider them in any theoretical view, as laying a foundation for the pradical part, as any other clafs, and perhaps lefs fo, fince 1110ft of them originally were little better than attendants in the copperhoufe, or colourhoufe ; hence their conceptions go little further than to a certain mode of operation, the only one they have feen ; and it naturally fur- ther follows, that good or bad, improveable or not, they rigidly adhere to it ; or, to make ufe of a more common form of fpeaking among fuch perfons, they only proceed by weight and mea- fure, (3) (hmilar to many cutters not having an idea (2) See the Introduction, where fuch freedom is apologized for. It may however here be added, that had the work been of a mors general or public concern, fuch particulars would probably not have been noticed.

As for copperwork, the principle of it h .;Ut fimple, though the various circumftanc&s that occur in the practice rentier it really of conie- quence ; the grand points depending on clean- linefs, and the neceffary degrees of heat, and if the obfervations on thefe objects be brought into fome plan, and attended to in the operation by the copperman, he feldom is in very great danger of failing ; (5) nearly the fame may be faid of the Foreman (5) Taking it for granted, that the preceding proceffes are perfect, the drugs and other articles proper, and making allowance for accidents that the utmoft carefulnefs cannot prevent, or what is Mill more impoffible to guard again ft, the wanton or mifchievous difpofitions of too many; fnniJar to what as faid in a note at the end of the feclion on pitches. — See likewife the hints offered to the co- lour-maker about printing, &c.

This idea could be purfued further, were it ncceflary, as it takes in the confideraion of acquaintancefhip, inter- cflednefs, dependancy, &c. which in every ftage of life tend to form thofe connexions that mere merit will not always command.

It may be proper to intimate, that in the Di- rections, &c. refpecting the operative parts, thofe points were chiefly attended to in which different pr clitioners nearly agreed; for, as two or three times obferved, what renders the difficulty great in ? Of Copper-work, Fielding, 13 c. in treating fubjects of this nature, is, that the tefcuflion appears no farther reafonable or proper tcwiny one perfon, than as it is reconcileable to his cVn ideas of practice; and there are feldomtwo who agree in the fame mode ; hence, it is endea- voured, rather than dwell upon certain little practical circumftances, to give fome general theoretical hints, as tending to convey what is fo very much wanted among the majority of thofe to whom this work is addrefled, that is, fome idea of the principles on which their ope- rations depend, as fuch a knowledge, if it can be conveyed, every one mull grant will more lead an operator towards fome perfection in his profefTion, than merely exhibiting a heap of practical di- rections, or difplaying a number of precife rules,, as all the experience attained from long practice will never form the adept, without a theoretical knowledge.

Now here, it is not rxecaufe there appears the fame body or mifc of colour in one as in the other, that an equal quantity of mad- der is neceffarily alike for each ten pieces, for, if there be barely enough to bring up the paleft, there will not be enough for the fecond, and itill lefs fcr the darkeft : and, invciting the rule, by having a fuiBcient quantity to bring up the darkeft, there will be more than fufficient for the pale fhades, and confequently fome mad- der will be wafted, from the amnion not being fo ftrong in the pale fprigs, through their con- taming a fmalter number of aftringent atoms, as in the darkeft -fprigs which have confldeiably more.

The above may be likewife inftanced in a piece of pale blotch work, and a piece of dark ; as in the dark blotch, there muft be a greater number of aflringent particles, and confequently their powers of attraction more multiplied than thofe in the pale blotch, from having a lefs quantity. In common engraved copper-plate work, this is evident in what is called the fpewing of the colour; but it is par- ticularly fo, in the tinted work lately introduced; for whether done in black, chocolate, blue or olive, according as the colour is received by the cloth from the lightly tinted parts, it fbews different fhades; hence in thefe cafes, as the colour is not previoufly thinned, it can only be occkfioned by the aftringent particles being more difperfed than in the dark places, oi\ in the -grounds. It may be lubjoined that there are cafes where the coppefman may be deceived in forting the pieces. -See note 21. Indeed it ishere aflerted, that the leading principle in copper work is properly forting them. As to the common wonder of printers, that pieces of the fame pattern, colour, &c. do not come up alike, See colour making, under the article of the application of colour by printing. 1 REMARKS Of Maddering. R E M A R K S, &c. In maddering, 3 certain diftincYions mould be made, tho' the copperman as juMaid, mould know- how to make more according to the lightnefs or heavinefs of the work. The three alluded to, are dark grounds, clofe covering work, and light grounds; but in this difVinction it is impoflible to afcertain here what quantity of madder to ufe, as a copperman who has attended the previ- ous proceffes, if the cloth has been well ma- naged in other refpe&s (faying nothing about what has been.juft difcufled) will bring up work with nearly half the quantity that fome others will; for too many if left to themfelves, rarely deal out madder with a fparing hand, (33) However, it (33) At a certain Ground (the writer thinks Newton's) where madder is by no means fpared, the Principal percieving one night a light near the Copperhoufe, found, on going thither, the Copper- man in the drug-room, adding more madder to what had been weighed out for him ; and it ap- peared, on enquiry, to be only for the purpofe of infuring his reputation as a Copperman, on the principle V — — a Of Madder ing, it may poffibly be faid, if it be of a good fpc'ndin e fort, heavy work may require feven or eight pounds to a piece, and for light work from four to fix. But all this, as obferved refpeS- mg aihing, fouring, &c. muft depend on dif- cretion or other circumftances ; for written documents cannot provide for every courfe of work. As to the general mode of procefs, according to the iize of the copper, the courfe of work, or dimenfions of the goods, tie up more or lefs, rarely more than ten of light work, but iefs of heavy: bring the copper to a fcald( 3 4) in about an hour principle above mentioned, of thinking he 'could not ufe too much. It muft be fuperfluoua to add, repeated circumftances of fuch a nature are of fbme pecuniary concern, efpecially where much work is done. (34) Tn * s term of a fcald is much ufed by com- mon coppermen, as they build their merit and certainty of effect on their judgment about it ; and here un- doubtedly they are right ; though few precifely Know why; for in this procefs, as well as in afliing cr fouring, there is a certain iniknt of time when the Of Madclerlng. hour and a half, and keep it in that ftate till the colour has fufficiently rifen. With light goods this firft fcald will anfwer for fumaching. After this fcalding, have them planked or warned, then enter them in fre/h madder, and bring the water to a boil in about an hour; but great caution mull be taken that the colour is raifed the effect is accompli died, which, chemically fpeak- ing, is the point of faturation, (fee note 1 6) and to carry the procefs on further mull: be injurious, or, at any rate, fupcrfluous ; which point of time is when the noxious or obflructive fubftance is decompofed or removed ; from an aflimulution with the alkali or acid then ufed. In -the fixing of colour, it is- when the combinat'.on of the falts and colouring particles is forn.ed ; for, as in ihe preparation, if there be any alkali or acid remaining in the copper, after the noxious fubftance is removed, it either has nothing to aft on, or it muft act on the cloth. So in maddering, or welding, if the cloth be kept in beyond the point of fat u ra- tion, or the water be too hot, the red or the yellow will probably be dingy, or otherwife injurej as well as the other colours, from the colouring particles aftiug with other powers, than their merely colour- ing ones.

Clcanlinefs haying been repeatedly mentioned, as a grand point of copper work, the copper man here is particularly advifed to it in the firft in- ftance of fupplying the copper with water, for if taken from fome firearm, various matters maybe brought down that may do confiderable injury. And in ground refervoirs or ponds, it fhould be noted that there be no influx of filth of any kind, and especially that they be not near ponds or other places where afhed or foured goods are rinced, for fear fuch foul waters find their way to them. (37) (37) Speaking of what may come down in a fiream, the following circumftance which happened fome time ago is quite in point. As a number of pieces were rincing, printed in chymick colours, to ihe furprife of the rincer, he found the colours changed. The caufe on examination appeared to be from a quantity of afli and other matters from the clearing- of the coppers, coming down with the fiream from an adjacent dye-houfe. As the purity or certain quality of water is of great conference, whether for Colour-making, Copper-work, or Fielding, it is juft intimated, thatitl gravity being generally in proportion to its purity, the common hydrometer will difcover it In Berg- man's works, his experiments on waters, in order to remove >7 Of Madderlng remove impurities, and render waters fit for various purpofes, are truly of importance to Callico- Printers, Dyers, and all who ufe confiderable quantities of it ; and in this cafe (as well as in others) if it were not from the fear of doing- a par- ticular injury, it could here be fhewn, from expe- riments actually made by the writer himfelf, which Printing-grounds in the vicinity of London, ,are more or lefs fortunate in that refpect.* In facl, it is matter of wonder this has not been more an ob- ject of enquiry among Callico-Printers and others, where the goodnefs of water is of fome concern ; efpecially as little trouble and expence are re- quired to render impure waters in certain cafes, and in certain quantities othervvife. Perhaps the lingular effe&s (as has bern obferved) of waters in India are owing to high degrees of purity, through a friendly interference of nature; and, as applicable to the fubjecl, it is mentioned as no fecret, that at , tpital Printing-ground near town, the waters of a very copious fpring, which for a time had been ufed for Fielding, were at lad, by accident, found not to be fo efficacious as the water that was rejected.— A Printing-ground could be * Amov.g >ht works referred to, may be found the modes of dor-; it.

It is a particular circumftance to attend to in printing-grounds, where printed goods are wa- tered (which the writer thinks is every where the cafc in this country) that the water be not hard, nor tinged by any mineral quality ; one realon for not watering on the Continent, may be, the waters there abounding with mineral im- pregnations ; indeed about London, work done in fome places, is clearer in . the white, from the fuperiority of the waters f and it is well known the foil in general in the north, from its . mineral; ^,«" Of Grafs-bleaching or Fielding* mineral quality, is unpropitious to producing a good white, and without a good white no work can appear perfect. — See note 6; That a deal depends on the foil and water is further evident in the cafe of foreign articles, particularly fome fromlndia ; for ata place called Seconge, the waters have, it is faid, a furprizing tendency to whiten the cloth,(37) and of <:ourfeto render the colours more brilliant, hence goods are brought thither from diftant places for that pur- pofe, as likewife to two or three other places on he fame account (37) This may be confidered philofophically as well as merely mechanically, the fenfation of colours being caufed by certain reflected coloured particles, or rays of light #riking the eye, according as cer- tain fubftances are difpofed to receive thofe particles, thus, a bright colour lying by a dull one, the rays from each being intermixed with each other before they reach the fight, the bright colour helps to enliven the dull one* and the dull one deadensthe bright one, fo in painting, it is not fumcient that fhadows be pro- perly difpofed, but that every colour, according to its ctuantity or proximity to another, communicates a portion to the parts near it, receiving; at the fame time,according to the law* of reflection and refraction, a portion likewife from the other.

Purfuingthis Idea further, fome will undoubt- edly -fay, who knows what may be produced from a -number of experiments, if only by mere chance? as many difcoveries originate more from accident than dehgn ; bui: Hill, all this is not a fufficient apology for making. experiments without certain principles at hand to proceed by, for without them, the practice mud be lefs pleafant, lefs likely to beYtfkctive, and what is of great concern indeed, lefs likely to be attained with little ex- pence ; but here it unfortunately happens, that of the greater number of fuch experimentalifts, is 'included thofe, who have a faiattering of the practice from having been afliltants to a colour- maker, or otherwifehave caught the idea for the practice, and purfue it eagerly, though under every difad vantage ; another clafs is among prin- cipals Of Colour- Making* cipals themfelves, who having ingredients at hand, rufh into the pra&ice of combining and com- pounding one thing with another, juft in the fame manner, and upon the fame uncertain grounds; the confequence, undoubtedly, is much anxiety and embarraflment, with very little be- nefit: as for the idea (juft mentioned) of fome- thing turning up by chance, that is too abfurd to give it countenance fo as to recommend a feries of experiments from fuch a hope ; but advice in this particular it is apprehended will not be of much avail, moft perfons in this cafe, imagining that if they have but opportunities of making-experiments or feeing the refult of them, or what is fometimes •worfe, getting together a number of reccipes, they may fave themfelves the trouble of ftudying the theory or principles of what they undertake ; for the idea of ftudying and ftoring the mind with certain regular ideas, carrying with it that of much labour and time ufeleffly employed, very few indeed by choice enter into it : but wa- ving all this, it may be faid, that even in fuch a vague courfe of practice, it would not be fo dis- creditable or unprofitable/if either clafs,juft Speci- fied, regularly made a point of transmitting to pa- per n Of Colour - Making. per the fequel of their experiments, ( 7 ) as even that would be of fervice, fince by fo doing, they might, at all times, fee where and how they have failed, or where they have gained any advance, and accordingly might afterwards proceed upon furer grounds: but even this is feldom done, though at all times neceffary, under every circum- flance,,ndeed it cannot be of much uft, unlefs the minutes are accompanied with proper refleaions on the probable caufes of their failure or fuccefs.

' 1 Of Colour - Making. Principals have in general enough elfe to mind to dedicate much time for that purpofe ; hence is another reason why little benefit is reaped from luch a chaos of uncertain or inconclufive ex- periments. After dwelling upon this inconclufive mode of pradice and the confequent circumflances, it may not be improper, by way of illuflration, to intimate in a general manner wherein fuch prac- tices fail, and then a word or two will be offered as recommending a properer mode of proceeding. It is firfl obferved, that the fubflances capable of producing ctfours, are ahnoft infinite ; fothat the field being very large, the mere dabbler has too much opportunity of fruitlefsly making at- tempts^: Some fubflances give out colours that can be removed by foap, fome will oppofe that, but cannot refill air ; and fome cannot be moved by either ; now refpetfing fubfi-ances that are not permanent or fall (according to the common phrafe) and known not to be fuch by a number of experiments; fome perfons have endeavoured to improve on them by joining a durable one to them ; blending them as intimately as poffible, from a preemption that the weak fubHance would Of Colour - Making* would have received affiftance from the other ; but it has always followed that the falfe colour- ing fubltance foon flies off, leaving the perma- nent one behind : Some have endeavoured to pro- cure a permanent one, by flrft putting on a fading one, and covering it afterwards .with a permanent one, on a fuppofition that the perma- nent one would fecure it, and by being exter- nally fituated, might defend that beneath it or within it, or at lead that it would operate in that manner for fomc time, fo that there might be a little longer durability to the fading one, but this likewile will not anfwer ; and in the practice of ufing acids, fome by endeavouring to mix various ones together, without knowing their qualities or affinities, have found the effect of one deftroyed by the effect of the other, like folution of. tin and cream of tartar, or folution of tin and facrum faturni, as the marine acid will quit the tin and join the . faccharim, the acetous acid being at the fame time fufpend- ed by it, is of no effect on the tin : — fee ex- periments of this kind further on ; others have had a notion that a mixture of different faits will keep the colours better ; but it is proved to have a direct contrary effect: : hence when they have acted in this manner, without any pofitive knowledge of the principles of this part \ Of Colour - Making. part of chemiftry, they have made fuch a eon- fufed mixture, that it was impoffible to know which ingredient, or what number of ingre- dients caufed the mifcarriage; much lefs to know in which was the efficacious property fought after. Now, in this cafe, it may be further laid, a neceflary circmnftance is omitted, and that is, firft of all to try. what effect each fait has on the colouring fubftance in regard to their fimilarity of effect or appearance, for in knowing this, there is the greater chance of fucceeding. But, if perfons will plunge themfelves into a practice of making experiments, let them begin with making them firft, with fimple folutions or ex- tracts upon feperate vegetable or mineral fub- jects, making fuitable remarks upon each re- mit ; though even that will not be fufficient, nnleis the qualities of the lolution are alike, or a previous acquaintance with them be obtained, fo as to know their different effects in point of flrength, or time of operation ; and this implies an abundance of food for obfervation, from the various mixtures that may he made only of one article ufed as a bafis, if confulered in its dif- ferent degrees of flrength or purity, and the dif- ferent fubjecls it may have to act on. How- ever, by proceeding in this fimple manner, they may Of Colour - Making, may then unite or multiply them. But if they proceed here in too precipitate a manner, they will prefently be bewildered, as it muft be clear from the above ftatement, even to an in- different perfon, into what numberlefs channels the fnnpleft mixtures of fimple fubjecls with each will run ; and much more fo when com- pound ones are taken; hence without fome clue in this praaice, the fame indifferent obfervers muft as plainly fee, that fuch operators muft very quickly find themfelves in an inextricable laby- rinth, hemmed in with doubts and difficulties, and if they proceed, it will be more from a fhame of going back, than from a hope of getting into any regular channel. In proceeding now to the intimation o£a more proper mode of making experiments, it is pre- mifed, that the confideration of colours (as may be fuppofed) is exhibited only as relative to printing, hence it chiefly alludes to thqfe that are permanent or fading, as applied to linea or other fubftances of the fame kind. By II \ I Of Colour - Making* By permanent colours, every one in the print- ing line confiders thofe that are not to be re- moved by foap, fun nor air ; the others are of va- rious kinds, as fome withftand warnings, but will fly on the air ; others will withftand nei- ther, and others only for a little time; but what is of the raoft concern is, that, witli few excep- tions, thofe colours that are the moft permanent, are the leaft brilliant ; though for this, it may perhaps be faid, that entering hut into the fu- perfices of the fubjecl: made ufe of, the colour- ing particles are more crouded together; and confequently exhibit their rays more glowingly than if more difperied or feparated ; which mull be the cafe when entered (as is fuppofed in the cafe of permanent ones) into cells adapted to re- ceive awd retain them ; and the more compound the colour is in refpect to its ingredients, it is the lefs vivid, and lefs likely to be durable. As to what bold fpeculatifts, or even expe- rienced practitioners may fuggeft, our know- ledge of the nature of colouring fubftances is very limited ; or if we know fomcthing of any fubftance in one ftate, that fubftance, when fe- parated, will prefent a new appearance in its fe- parated parts, and fo on ad infinitium ; hence, L likcwife ' •Of Colour - Making* likewife is our knowledge very fmall indeed in judging or determining on the refult of thofe applications of one fubftance with another, for the purpofe of difcovering or fixing of colours. In fimple proceffes, inftances are very rare of perma- nency, but of any combination of ingredients, when one article feems to bid defiance to the great proofs of air and fun, there is the obj eel: for investigation ; and therefore in colour- mak- ing* a great point is to difcover thofe articles that naturally poflefs thofe permanently tinging qualities, or that can eafily, and in the fimpleft manner be procured by a combination with fome Other. As it is not certainly known, nor perhaps will it ever be, why fome colours fade, and others will not, fuppofitions have been formed, fpe- cious enough (as already exhibited) though they are received not as being indifputable, but only as the bell or moft rational, that can be given. The moft remarkable inftance of fimple fub- ftances for giving out their colour, as it were fpon- ■■ Of Colour - Making, fpontaneoufly, was in the tyrian dye, (8) which had power enough of itfelf, (imply to communicate to filk and fome other fubftances, a colour as firmly as can now be procured by any procefs whatever: Other inftances are in the folutions of indigo and filver ; the latter when mixed with chalk (8) In the Spanifh feas is found a mell-fiih that refcmbles the antient purpura, the purple dye is in its throat ; Cloth of Segovia i* dyed with it, and >ears a high price. The colour from the fifh when firft laid on linen, is a light green, which by the air- is changed to a dark one — in a few minutes to a fea- green— a little while longer into a blue — from that it turns to a purplifh red — and in an hour or two to a deep purple ; here the fun has no more power, but by warning it in fcalding water and foap, and drying it, the colour ripens to a beautiful bright crimfon. The Americans of Peru and Chili had, knots of wool, which by the variety of their colours ferved for characters and writing ; the knowledge of thefe knots was called guipos, and was one of their greatelt fciences. The Otaheiteans procure a beautiful crimfon by mixing the yellow juice of a fpecies of % with the juice of fern. Of Colour - Making* chalk turns the fediment to a purplifh black when expofed to the fun, or rather the action of the fun's heat is the caufe ; the other cir- cumftance refpecting indiga, is perhaps more known to callico printers, in the folution at firir. appearing green, 'but on expofure to the air turn- ing to a blue, as obferved in another place. Having fpoken of the vague and inconclusive ©perations of many, the following difplay of the inftitutes of chymiflry in view of eftabliming one on a firmer bafis, is humbly offered, which will be followed by a few thoughts immediately relative to the practice of what is the fubject of this feet ion. It has been faid, that an acquaintance with chemiftry is indifputably neccnary for a colour- maker to have, but it muft be underftood not in every divifion of it ; as chemiftry, in its exten- five fignification, compriz.es confiderations that have little to do with the fubject of this trea- tife ; therefore the elementary parts and princi- ples only will be juft touched on, as leading to what is the principal object of it, that 1 Of Colour - Afaking, will require 806 times that bulk of air to be of the fame weight, taking the air in its common ftate, the bulk as before faid, being continually fufceptible of change, W A T E R.- This is a tranfparent and in lipid fubftance,- and fluid or folicl according as affected by heat or the privation of it; its natural ftate is fuppofed -to be folid, and rendered fluid only by heat ; ex- pofed to adlual fire, it acquires a certain heat (by boiling) beyond which the greate'ft force of fire can never raife it; the effecls of dilatation (as when a fmall quantity is thrown upon metal m fufion) are occaiioned by the air it is fuppofed to contain, and like air it enters into the com- poiltion of molt bodies, except metals and mi- nerals, as it is only fuppofed to be interfperfed between their parts, without entering into their conipoftion. E A R T H. This element is different from thofe juft men- tioned, in being fixed ; they being volatile, c* oaiily feparated by the adion of fire, from the bodies with which they may be united ; hence earth abfolutely pure cannot be affe&ed by any •peration Of Colour - Afakirrg, operation , and refills the utmoft force of the flrongefl fire, being the caput mortuum, or that fubflance left after a chymical procefs, which to all perception cannot afterwards be changed. Earth may however be divided in refpcct to its qualities, into verifiable and unvitrifiable ; one that will melt by fire and become glafs, and the other that will remain unaltered, fuch as fand's, which are likewife called abforbents, from their quality of imbibing liquids* FIRE. This element is divifible into that which is concluded to originate from the. fun, and that which is called phlogi&on, as being univerfally held a sonftituent part of any body : that coming from the fun may be called a fluid fubitance un- interruptedly flowing from him, and dirrufing itfelf through the whole planetary fyflem, and every particle of matter in it, but not as a native principle ; hence it may be fuppofed the air itfelf would become a folid mafs without this interve- ning and active principle ; its rarefaction and condenfation, with the dilatation of water, and fimilar effects produced in the eartli originating from it ; and in all our operations it is the moft powerful agent, and when collected in the focus of Of Colour - Making, of a large lens, is at the greateft pofl&ble height producible by human art. , What is underftood by. phlogifton feems to be different, being apparently fixed to all bodies, fo as to make a part of them ; but how fo a&ive, or, as it were, fo reftlefs a fubftance can be fo fixed, is not yet determinable, as it differs from elementary or pure fire (juft fpoken of) in com- municating neither light nor heat when joined to any other fubftance, and produces no change in its fiate ; fo that a folid body becomes not fluid, nor a fluid folid, by its abfence. The fign ot any fubftance containing phlogifton, is its being capable of taking fire ; but, as in the cafe with, metals which abound, with it, and which are not inflammable, it is not thertce inferred they have. none. Thus a body may be faid to contain, its phlogifton, when after a flame fubfides it fparkles or wafies, till reduced to a coal ; and, adverting to the fubjeel of colours, it is known^ that the number which we perceive is owing to the varied combination ofphlogifton, with oils, earths, and falts. The Of Colour - Making. The next general confideration is, that of Se- condary principles, ( 1 1) which are conititutcd chiefly of faline and oily parts; and as all the experiments that have been made, prove there is fuch a mutual agreement, connection, or depen- dance on one part with another, the knowledge of what fubftances thus agree or difagrec, under their various^ccmbinations, forms (as mufl be clear to every one, and which has been repeatedly enforced) the foundation of fbine certainty in making experiments for any purpofe whatever ; but before that can be known, in refpect to parti- cular fubftances, the nature of this univerfal affecYion mould be conceived, and likewife what are the affinities of the different claffes of fub- ftances which comprehend the fpecies belonging to them ; therefore the folio wing poftulata or proj>oiit4ons received as fundamental truths, (fimilarto axioms in mathematicks,or maxims' in common life;) and the table or fcheme of affinities which will afterwards follow, have been formed for that purpofe. I. Any (i i) So deemed as containing yi analyzation of fubftances more fimple than what.they help to form, and are yet compoled of primary principles. Of Colour-making, I. Any fubftance having a conformity with an- other, the two will unite and form one com- pound. 2; All Ample fubftances have affinity with each other, and will confequently unite; fuch as water with water, fire with fire, &c. 3> Subftances when united together Iofe fome of their refpectivc properties, and the com- pounds refulting from their union partake of the properties of thofe fubftances which ferved as their principles. 4. The fimpler fubflances are, their affinities are more perceptible; hence it is raoft difficult to • analyfe bodies that are the leafl compounded. 5. If to a compound, confuting of two fubflances,. a third be added that has» no affinity with one, but has a greater with the other, than the firil 2 combined have with each other, a new de- compounding, and a new union mull en- fue. (11) (11) Thus if you pour vitriolic acid on com- mon fait, the mineral alkali having a greater attrac- tion for the vitriolic acid thai for the marine; Uivcs - Of Colour - Making, 6. A third fubftance offered to a body confining of two, no decompofition may follow ; but the two uniting with the third, without quitting each other, may form a union of three princi- ples ; prefuming the third fubftance has an affinity, or nearly equally fo with each of the other fubftances.(i3) 7. Though a compound confuting of two fob-' fiances, having a greater affinity with each other than with a body prefented to them, may not be decompofed by it ; yet that body, when combined with another, liaving an affinity with leaves the latter and unites with the former. The vitriolic acid is alfo faid to have a ftronger attraction for the mineral alkali than the marine acid'has : hence the former acid is faid to expel the latter from its bafis ; or it may be faid demonstratively thus ; If A being united with C, upon B's being after- wards applied to them, lets go C and joins B, A is faid to poffefs a greater attraction for B than C. (13) Thus when pure calcareous earth (lime) is duTolvcd in the nitrous acid (aqua fortis), a cauftic volatile alkali will not difunite them, becaufe the att ra&ion of the alkali with the acid il not fo ftrong a« that of the calcareous earth* { Of Colour - Making. with it, compen fating for its want of it with the others, may fepafate the two, by uniting with each of them ; therefore in this cafe there is a double affinity, a double decompofition, and a double combination. (14) What next follows is a table of affinities, or elective attractions, of one fubftanee to another, or a more fpecific representation of the fubitances juft alluded to, in the relation they are obierved to have with other as productive of thofe appear- ances that enfue by their operation on or with each other ; the fubftances in each- column' or divifion are placed in the order they agree with that at the top : thus in the firft divifion, Vitri- olic Acid ftands at the top ; accordingly the fubftanee that has the neareft affinity to it? is JPhlogifton (14) Thus, to pure calcareous earth diflblved in nitrous acid, . i m Fixed Air, Calc.

Example In an injlance of Jingle attraction. Apply to cinnabar and iron filings, a certain heat; the mercury of the cinnabar will rife, and leave the brimftone, its other element, combined with the iron, which it attracts in preference to the mercury. Example In an injlance of double attraction. Unite mercury with common fait, by means, of a like certain degree of heat, a new compounded combination will commence among the fub- ftances : by the marine acid of the common fait joining the quickfilver of the mercurial fait, forming a new fait called corrafive fublimate, while the mineral alkali of the common fait ■unites with the vitriolic acid of the firft mercu- riaJ fait, and forms what is called Glauber's fait. ^^— I Of Salts in General, or Saline Subf1ances y comprifing Acids, Alkalies and Neutrals, O ALINE fubftances are combinations of earths ^ and water, or they are combinations capable of uniting with either of them, or with both to- gether, for all falts are refolvable into earth and water, and the more or lefs they are united to their earths, they are fixed or volatile, which circumftance makes the difference between acids and alkalies. Acids are the fimpleft of falts, uniting readily with water, are fharp to the tafte, and have the diflinguifliing property of turning vegetable blues and violets red. Alkalies have a greater proportion of earth than acids have, and have lefs affinity with water, but unite violently with acids, producing an effervtt-- cence and hi (Ting ; they are fiery and acrid, to the tafte, and turn vegetable blues and. violets green. Neutral Of Colour Making* Neutral Salts are formed from the union of an ;acid and alkali, by which union they rob each other of its properties, which are then fo blended that neither predominates, and which inti- mate union is called the point of faturation: they produce no change in the blue colours of vege- tables, and are neither acrid or four, but fait, fuch as is the taile of kitchen fait, and are ge- nerally known by the plain general term of falts. Imperfect neutrals are thofe in which either the acid or alkali predominate. Of the univerjal or vitriolic Nitrous and Marine Acids* The univerfal acid, according' to its name, is found diffufed in the waters, in the atmofphere, and in the bowels of the earth, but feldom pure or unmixed with other fubftances; what the greateft quantity is collected from is vitriol, hence it is called the vitriolic acid ; and when it contains only juft phlegm enough to give it a fluid form, it is called oil of vitriol; if it contain much water, it is called fpirit of vitriol * when it has not enough to render it fluid, it is called the icy oil of vitriol. This acid combined with a certain abforbent earth, with the nature of which we are unac- quainted Of Colour Making, quainted, forms a neutral fait called allum ; dif- fering in quality according to the earths with which the vitriol is combined : An alkali being prefented to allum, the acid will quit the earth and join the alkali, and from the junction of the vitriolic acid, with a fixt alkali, a neutral fait is formed, called either arcanum duplicatum, or variolated tartar ■, one of the fixed alkalies mofl in ufe, being fait of tartar.-— See Maddering, and note 27. The conjunction of this acid with phlogifton forms fulphur. Nitrous Acid, This is no other than the vitriolic acid com- bined with phlogifton, by the agency of putre- faction, at leaft fuch is the received opinion, the nitrous acid being found only in earths and ftones, impregnated with matters fubject to putre- faction ; when combined with chalk, ftone, mar- ble, 6cc.it forms a fait, that does not chryftalizc, which runs in the air, per deliquium, r and is de- compofed by fixed alkalies, with which the acid unites and quits the earths, and from this union refults falt-petre. The raoft remarkable and diflingurfhing pro- perty of nitre is its difpofition to unite with phlogifton, Vf Colour Making. plribgifton, in its pureft /late, fuch as char-coal, fulphur and metallic fubftances ; thence burfting; into a flame with great noife,. called its detona- tion or deflagration, in which cafe the acid is diffipa'ted, and the alkali which is left is called fixed alkali. A nitre isto be procured by dropping into fprm£ water, a folution of fixed alkaline fait, filtrating the*liuuid and evaporating it to a certain decree. Afarine Acid sr Sea-Salt* Iq refpeel to the conftituent parts of this acid, wherein it differs from the vitriolic and nitrous, it is not certainly known, no more than it is wherein they differ from each other ; but when combined with abforbent earth (lime or chalk) it forms a neutral fait, that does not chriftalize, and when dried, attracts the moifhire of the air : This acid, like the others, has lefs affinity with earths than with fixed alkalies, but as well as the others have, it has a greater with phlogifton; and- when combined with fixed alkali it forms a neutral fait which fhoots into cubical chryftals and is inclined to run in the air. The acid of this fait when freed from its bafis, is called fpirit of fait, and when containing little phlogifton, 1 Of Colour Making* phlogiflon, it is called the fmoaking fpirit of fait," from its then continually emitting vapours. Combined with phlogifton, a kind of fulphur is the refult, that takes tire on being expofed to the air, called phefphorus of urine, being gene- rally prepared from urine. India fupplies us with another acid called bo- rax, which flows and takes the form of glafs,and pofleffes fome of the properties of fixed alkali. LIME. Any fubftancc that has been roafled in a ftrorig fire without melting, is called a calx ; flones, (which are fubftances compofed of different earths) reduced to this ftate is called lime; this applied to fixed alkalies make them more active and renders them corrofive or cauftic, and from which the common cauftic ftone is prepared : Lime unites with all acids, and chryftalizcs with the marine, but not with the nitrous. Quick lime attracts the air like concentrated acid, and dry fixed alkali, but not fo as to render it fluid ; it only takes the form of a powder, and is then called flacked lime ; when once flacked, though it feem ever fo dry afterwards, it requires a violent calcination to feparate the water from it, Of Colour - Making. it, which it had imbibed. Sand is mixed with it in making mortar, or it would otherwife con- tract and confecjuently crack and break. In Chemiltry it is deemed holding a middle rank between abforbent earths and fixed al- kalies. Metallic Subjlances. Thefe confirt chiefly of a verifiable earth combined with phlogifton, and are therein fu- fible ; they are likewife ponderous, opaque, and fparkling : a third principle is contended for by fome chymills, called mercurial earth, but it is doubted to exiftby others. Metallic fubitances readily unite with mofl acidsj and in that cafe an ebullition with va- pours ari.fe ; by degrees the metallic particles become inviiible in their folvents, and the metal is then faid to be difiolved ; but, as with alka- lies, an acid can only take up fuch a portion as is fufficient to defiroy fome of its properties, and to render others weaker. The affinity that me- tallic fubftances have with acids, is lefs than M what I Of Colour - Making. -what they have with abforbent earths and fixed alkalies, fo that the acid which will unite with ihefe fubftances, will decompound the metalline falts, and precipitate the metal, which are then called precipitates and ma&erkries. Metallic fubftances are 6 in number, 2 perfect viz. Gold (Sol) Silver (Luna) and 4 imperfea, viz. Copper (Venus) Iron (Mars) Tin (Jupiter) andLead (Saturn ;) Quickfilver (Mercury) is by fome, called a feventh metal. GOLD. As metals are the heavieft fubftances known, gold is the heavieft of all, and when pure, is unalterable in fire as far as any experiment hath hitherto proved* neither can it be diflblved by any pure acid ; but only by the acid of nitre niixed with that of fea-falt, called aqua regia. Goldislikewife the moft du&ile and moil: mal- leable of all metals. Aremarkablecircumftance,andasyetnotclearly accounted for, is the fulminating quality of the precipitate by an alkali or abforbent earth, gently 4ried and expofed to a certain degree of heat j lit Of Colour - Making* heat; this is called aurum fulminant ^ but the acid of vitriol poured on it, will deprive it of that quality, as will likewife be the cafe, if it be cleared of its faline particles, which, warning it in water will accomplish. Gold is not arlecred by a pure fulphur when combined with an alkali. SILVER. This metal is the next perfect to gold, being lighter and lefs du&ilg, but like gold it refifts the greateft force of lire, in which is their fu- periority over all metals : The true folvent of filver is the nitrous acid, the chryflals formed thereby are particularly cauftic ; it is likewife foluble bv the vitriolic acid, if it be concentrated, but fpiiit of fait, a»d aqua r^gia, as well as the other acids, are not capable of affecting it : yet in reality it has a greater affinity with both, than with the vitriolic ; for if the vitriolic or marine acid be added to a folution of filver in the nitrous, the hlver will direaiy join it, and the precipitate procured by the marine acid, is called Luna Cornea : Fixed alkalies and abforbent earths will feparate the filver from the nitrous acid, though the nitrous acid cannot ad on it when mixed with an equal quantity of gold, but when Of Colour Making* when in a triple proportion it can with eafe : If aqua regia be employed when they are in equal quantities the feparation will be effected, by the gold being diffolved and the filver left free ; but the operation by aqua fortis is to be preferred, it having no effect on gold, and a little of the fil- ver is always taken up by the aqua regia : Silver united with fulphur foon flows, and forms a mailable mafs, the colour of lead :— Solution of filver in the nitrous acid ftains hair, bones, wood, &c. from a brown to a black, and gives a ftaia to marble and other ftones. COPPER. This is the firft of the imperfect metals, it refifts fire a long time, unites readily with gold and filver, and is foluble in all the acids, neutral falts, and even in water; to fome imparting a green colour, and to others a blue : diffolved in vitriolic acid it forms blue cryflals, called blue vitriol or vitriol of copper : diffolved in aqua regia, the marine or nitrous acid, it forms a fait which does not cryrblize, and runs in the air: The precipitates by alkalies or earths re- tain Of Colour Making*- tain nearly the colour the folution gives : mingled with nitre and expofed to the fire, as well as the other imperfect and femi-metals, it is fooner decompofed and calcined than if prefented alone : mixed with fulphur and made red hot, it foon melts and forms a new compound more fu- fible than alone. r R O K. This metal ftands alone for its property of being attracted by the magnet, but lofes it if reduced to a calx, or converted to an earth : by repeated melting it is rendered purer than by having only undergone fufion, but is not malleable till after being heated red and hammered in all directions : before this procefs it is called pig- iron but bar-iron afterwards ; and is then harder to fufe : Fufing it with articles that contain phlogifton, or enclofing it in phlogifton matters, and expofmg it thus in juft a red hot flate for a certain time, it is converted into fteel or harden- ed: Suddenly quenching it when red-hot in a cold liquor, the hardnefs is augmented, and that in portion to the heat of the metal and coldnefs of Of Colour - Making, Si 1 V of the water ; it may be brought back by ceme n- ting it with calcined bones, chalk, &c. rendering it red hot and leaving it to cool gradually, or if heated alone, and left thus to cool, the temper given to fteel is deflroyed. Iron being calcined turns to a yellowifh crufV, by lofing its phlogif- ton, and is then called crocus mmrtls or faffron of mars. All acids, as well as certain falts, alkalies, and water itfelf, operate on it, but the vitriolic acid diffblves it t,he readieft, rendering the folu- tion of a beautiful green ; the cryflals produced by which are called green vitriol, vitriol of mars, or copperas : Ochre is the fediment produced from green vitriol difTblved in water : Spirit of nitre duTolvcs iron with eafe, producing a brown* ifh yellow, but the calx formed by this folution cannot be a fecond time diffblved, for having loft its phlogifton, the nitre will not act on it, neither does this nitrous folution cryltallize : The folution by fpirit of fait is green, the va- pours of which are inflammable, as well as thofe caufed by the vitriolic acid: the folution in aqua regia is yellow. Iron having a greater affinity with fpirits of nitre and fpirits of vitriol, than either lilver or copper has, if offered to a folution of either, the lilver Of Cohur Making*- filver or copper will precipitate, by the acicf quitting them and joining the iron : Jron filings expofed to the dew, turn entirely to a ruft, called crocus martis aperiens : united with fill* pliur, it acquires a great degree of fufibility: Iron makes a part of almoft all fubftances (which the magnet will difcover) it is found in the caput mortuum of all vegetable fubftances, even in honey, the earth being fuppofed to be impreg- nated with a ferruginous or vitriolic matter, and from thence received into vegetables, and from' vegetables it paries into> animals: It is the only metal that fparkles in the focus of a burn- ing glafs. „ TIN. This is the lighten: of allmetals, has but little du6r.il ity and runs long before it is red hot : The calx when vitrified, being mixed with fome ©ther fubflanee is called enamel, which is differ- ently coloured by means of other metalline calces : Tin unites with all metals, but deftroys their ductility and malleablenefs, lead excepted : Thofe the moft ductile it effe&s the fooneff, and in the greatefl: degree: Bronze and bell- metal are made from a compofition of this metal with zinc ; mixed with lead it produces pewter, ajid I' I M Of Colour - Making. and is ufed With quick-filver in making looking- glaffes. The vitriolic, nitrous and marine acids have an affinity with it, but cannot eafily ciiffolve it, as they only reduce it to a kind of calx : The proper folvent (as mentioned more fully further on) is aqua regia, and has even a greater affinity with it than with gold; Gold precipi- tated by tiiis method is a mofl: beautiful colour, and ufed as a red for porcelain and enamelling : It has the property of giving red colours in ge- neral, hence tin veffels are ufed in making fine fyrup of violet. It is not affected by water as iron and copper are, but it lofes its polifh on ex- pofure to the air : It readily unites with fulphur. LEAD. This is the heavieft of all "metals, gold and filver excepted, is fofter than any, and except tin, melts the eafieft : Vitriolic acid affects it nearly as it does filver ; the nitrous acid diffolves it with much eafe, and in great quantities ; the cryftals are of a fweet tafte, of a yellowiih co- lour, and are not eafily diffolved in water : Spirit of fait, or the fait in fubftance, added to the folution in nitrous acid, produces a white precipitate called plumbum cornea, which dif- folves k. ■U^MW Of Colour -making, . folves eafily in water : Being melted, it hardens into a kind of horny fubflance, like the luna cornea (whence the name:) Lead boiled a long time in a lixivium of fixed alkali will partially diffolve : It is rendered very refractory by fulphur. QU ICKSILVER. This fubflance is foluble in acids, but to each acid, particular circumftances are annexed ; thus the vitriolic acid concentrated and made boiling hot, reduces it apparently to a white powder ; which on the affufion of water turns yellow and is called turblth mineral, Quickfilver is eafily dhTolved by the nitrous acid ; the folution is clear, and as it cools fhoots into cryftals: If evaporated to drynefs, it pro- duces*'red precipitate : With folution of copper the precipitate is green. . Combined with marine acid, it forms a metal- line fait, the cryftals of which, called corrojivc fubllmate, are pointed like daggers, and is the molt, violent corrofive hitherto difcovered : From this fublimate is produced yellow precipitate : Quickfilver unites with fulphur very eafily, and produces by the mere mixture, ethiops mi- f ncral : Of Colour - Making. neral : By rendering the union more perfect by a ftrong heat, a ponderous fubftance is procured called cinnabar, which finely ground produces Vermillion, Of Semi - Metals, Namely, Regulus of Antimony, Bilmuth, Zinc, Regulus of Arfenic. Reg. of antimony has the'brilliancy, Opacity, and gravity of a metal, but like all femi-metals, crumbles under the hammer : It foon diffipates into fmoak and white vapours by a violent heat ; flowers of antimony are thofe vapours, collected "by any cold body, which ftops them in their afcenfion. Its affinity is greateft with iron, copper "next, and then with tin, lead, ai d filver. Its proper folvent is aqua regia, marine acid next, if highly concentrated and applied by dif- tillation ; The vitriolic acid likewife difTolves it, but with the nitrous it is little more than cal- cined. Liver of antimony is procured by mixing nitre with it, three parts nitre and one of antimony produces Of Colour - Making. produces a calx called diaphoretic antimony, or diaphoretic mineral. Antimony is \ifed to feparate gold from other metals, and the precipitate from its union with an alkali, is called the golden Julphur of antimony. BISMUTH. This fubfbnce is rather dulkier than the for- mer, and like other femi-metals is volatized with a violent heat : It mixes with and quickens the fufion of all metals, whitens them, and deftroys their malleability. Bifmith is not foluble in the vitriolic acid, but in the nitrous it diflolves with much fume : Marine and aqua regia diffolve it, but with lefs rapidity ; alkalies, and even water only, preci- pitate it, forming the ma gift l ery of bifmuth*. In its union with fulphur it forms a compound, ap- pearing like needles lying fideways by each, other. Z INC. Zinc differs little in appearance from Vifmuth, except having a bluifh cafl, though eflentially it differs very much : It melts the moment it grows red, foon turning to a calx ; ' and in an augmen- ted heat burns like an oily matter, evincing the great quantity of phlogifton which it -contains. I ■• m 0/ Colour - Making, It unites with all metallic fubftances except Bifmuth ; It is foluble in all the acids, particu- larly in the nitrous ; fulphur has little or no power over it. It has a greater affinity with the vitriolic acid than iron or copper has, forming a precipitate called white vitriol, or vitriol of zinc : United with copper it makes brafs, pinchbeck, &c. Regulus of ArsEnic This readily unites with all metals, and is the moll volatile of the femi-metals, flying off even by a moderate heat : the calx is plain arfenic ; the properties of which are peculiar to itfelf, having great volatility, having a faline charac- ter, being foluble in water, and exceffively cor- rofive, a quality none of the other femi-metals poflefs : It cannot be decompounded by any acid, except when joined to metallic fubftances : Com- bined with the alkali of nitre or fea-falt, if they be in a fluid, ftate, it forms a lingular faline com- pound, called liver of arfenic : Arfenic unites readily with fulphur, and produces yellow orfiiment. Inflammable Inflammable Sub/lances. Thcfe are Sulphurs, Oils, Refins, Bitumens, Spirits of Wine, Charcoal. ALL bodies probably contain more or lefs phlogifton, but thefe are deemed inflammable in which it abounds, but with which, at the faros time, it is not fo intimately blended, but that it may be driven out from them, under certain cir- cumftances, by the intervention or ruining in of the air. Sulphur(as faid before) isthe vitriolicacid com- bined with much phlogifton. Oils are mineral, ve- getable, or animal, and are, in general, nnduous bodies, that burn and confume with flame and fmoke, containing phlogifton ; which by means of an acid is united with phlegm or water, toge- ther With, a certain portion of earth : Nitrous and vitriolic acid, act on oils according to the portion of phlegm which they contain. Charcoal, or any charred matter, is what is left from the burning of any vegetable or animal matter, that has an oil united to much earth ; this fubftance is unalterable by any other body than fire ; hence acids ever fo highly concen- trated have noefLc.1 on it. Refins will be fpoken of in the next feclion. Of Vegetable Subftances. From the analvfis of vegetable fubflances, It is clear they contain phlegm, an acid, alight oil, much air, and a thick oil, but none of thefe principles can be obtained pare by mere difti Ra- tion, as their feparation is only began by this pro- cefs, therefore others are adopted to compleat the analyfis. Some vegetables, by analization, prove that they contain the fame principles as animal fub- flances poflefs, and inflcad of yielding an acid, a volatile alkaline only is to be obtained ; proba- bly becaufe the acid of the vegetable fuffers fuch changes when it enters into the compofition of animals, that is, it combines with fome of their 4 earth and oil, in fuch a manner as to be changed into a volatile alkali. In burning any vegetable fubflance in the open air, the analyfis is more rapid and com- pleat, burning till all its oil is confumed, and a coal remains, and this continues wafling till all its phlogiflon is dimpated, what then is left is its earth Of Colour - Making* earth and fixed alkali, commonly called the allies. Water, the natural folvent of falts, takes all of them up that are contained in the afhes, fo that by lixiviating them, nothing at laft is left but the pure earth. All balfams, as well as turpentine, are oily aromatic matters, procured by different methods from thofe trees which produce them ; thefe abound with efTential oils feparated from the ve- getable in which they exift. Refins are diflinguifhed from natural balfams by containing lefs oil, and more acid, fo that they are lefs difpofed to be fluid, and are foluble only in fpirits.pf wine ; they however differ from each other according to the quantity or quality of acid to which they owe their confiftence : The faline'character of Benjamin is evident from its being foluble in water, but then it muff be boiling ; the fait produced from it will chryftal- lize and may be diflblved in fpirits of wine. Gums differ from refins m being foluble in water, but (as before faid) refins are not ; refm being an efTential oil grown thick, and have an aromatic cdour, which gums have not: tfce fmall portion of oil which gums contain, being fo tho- roughly mixed with their 'acid, does not hinder their Of Colour-making, their dhTolving. in water, and therefore they rc- femble honey, and other vegetable juices, in be- ing originally fluid, and only grown hard by the evaporation of their moifture ; the fame as reiins become folid by lofing, in the fame manner, their fluid parts : but ingum-refins, the two qualities are fo blended, that each will diflblve in its proper menftruum, leaving the other entire. Sugar, manna, and all the faccharine juices of fruits and plants, are of the nature of honey, containing a phlegm, an acid, an oil, anda coal : but differ from refms in not being inflammable, or will not flame till nearly reduced to a coal : All thefe fubfrances are deemed natural foaps, confifting of an oil rendered miffible with water by means of a faline fubitance, but differ from common or artificial foaps in having their faline part an acid, while that of the others is an alkali: Why they are fweet, thongh containing much acid, is from the acid being intimately fheathed. or fmoothed by the oil : Of foap it may further be faid, that alkalies or acids combined, in a cer- tain manner with oil, produce them ; for oily and faline fubftances combined, follow the fame rules as other combinations, by reciprocally com- bining the properties belonging to each other, and Of Colour - Making. and (according to the rules of affinities) foaps are decompofed by alkalies, and alkalies by- acids. The moft expeditious mode of making a foap (being Dr.Lewis's improvement onMr.Beaume's) is, by heating the alkali red hot, then throwing it into oil of turpentine, and ftirring them well together ; in time, a fait cryflallizes both within it, and over its farface, but its nature is un- known. Of Animal Sub/iances. Thcfe produce jellies, which when infpifTated and become folid in the cold, form glue, and by the evaporation being carried further, it becomes horn. This jelly, or gelatinous fubftance, is the only true animal one ; as all human parts, bones and 'all, are to be reduced to it ; the other properties it has in common with vegetables gums or mu- cilages, except that the animal one makes a ftxonger cement: Acid, and alkalies particu- larly, eafily diflblve animal jellies; but the na- ture of thefe combinations is not known. i Of Earths. Earths are either ponderous ; calcareous (Lime) magnefia ; argillaceous (Clay ;)ox filicious (Cryjial) They are characterized by' remaining unaltered in a red heat, and of thofe five above' mentioned no one has been yet able to decompofe or tranfr unite one into another. Ponderous earth forms with vitrolic acid, pon* derous fpar, and is not foluble in one thoufand times its own weight of boiling water. Calcareous earth faturated with vitriolic acid, forms gyp/urn*, known by the property it has of forming, after a flight burning, a hard mafs with water. "Magnefia faturated with vitriolic acid, forms what 'is called: Epfomfafu Pure argillaceous earth with vitriolic acid forms an allum. The above four kinds may be called abf or bent earths, but the laji has the leaji claim. Silicious earth is not affe&ed by vitriolic acid, it is however diiTolved by that of fpar, the dia- mond excepted, neither is- the diamond changed by the greatcft heat, if not expofed to the air. Of Fermentation and PutrefaElion* By fermentation is underflood (as partly men- tioned before, fee notes 12 and 33 in copperwork) be a fpontaneous motion in a body, by which a new difpofition and combination of its parts is produced : To procure it there mult be a cer- tain proportion of watery, faline, oily and earthy parts, the fubjecT: muft be in a temperate heatj and have the affiftance of the air : And as all animal and ^ vegetable fubftances contain the principles juft mentioned, they are of courfe all fubje6l to fermentation : Minerals are excluded, not being as far as can be diicovered, fubject to this operation. There are three fpecies of fermentation, the vinous or fpirituous, or what produces wine, and fpirituous liquors ; the acetous or what pro- duces acid liquors, fuch as vinegar ; and the putrid, or what generates an alkaline volatile fait. The fubjects of the fpirituous are moft fruits, feeds and grains, dijuted with a certain quantity of Ill Of Colour -Making. of water ; by certain procefTes, air bubbles arite with vapours, To extremely active and pernicious that without caution the effects may be fatal, this operation, if not flopped, will proceed to the laft ftage, namely putrefaction ; the imparities then precipitate and leave the liquor clear and tranfparent. By diftillation an inflammable liquor light, pleafant and penetrating is drawn from wine that has fermented, which by repeated procefTes become more .and more rectified, and is called fpirit of wine ; and if confiderably purified, an ardent fpirit ; which burns without fmoak or leaving any coal: united with acids they lofe their pungency, and are faid to be dulcified. This ardent fpirit may, however, be rectified, or en- tirely dephlegmated till it produces aether, which is fo volatile that it flies off in the air, fires at the approach of a flame, and leaves not the leaft appearance of allies ; diffolving oily matters with the greateft eafe, and has a greater affinity with gold than even aqua regia has. Befides this ardent fpirit, a deal of water, oil, earth, and a kind of acid is afforded by wine, which when the fpirituous part is extracted fuf- fers no farther change : but if they all remain, the Of Colour - Making. the fermentation, after fome time, will begin again, the liquid turns four, and then acquires the name of vinegar ; but this produces no nox- ious vapours, nor depofits any tartar : Wine however is not alone the fubject of acetous fermentation, for feveral vegetable, and even animal fubftances, not fubjedt to the fpirituous turn four before they putrefy : this acid has the fame properties as the mineral, and has effec~l on the fame fubftances that the mineral acid has but in a weaker degree : It has a greater affinity with alkali than fulphur has, and a neutral oily fait is formed from its faturation with a fixed alkali. By its folution in fpirits of wine, is pro- duced regenerated tartar: Several faline com- pounds are produced by its union with calcined pearls, corals, fliells, &c. it perfectly diflolves lead; converting it into a neutral metallic fait, from which is produced Sal Saturnl, or Sugar of Lead, becaufe of its fweet tafte; The vapour of vinegar has that effect on lead as to produce arufs : Vinegar likewife corrodes copper, and converts it into a green ruil, called vcrdigreas, though not commonly employed for that purpofe, wine, or the rape of wine, being more ufed. Tartar *i - Iron liquor, Hartfhorn, (21) 6cc. Other articles might be added, but the above are chiefly in ufe. — See account of drugs, &c. further on. \~ (21) The goodnefs of drugs is of the utmofl con- cern, and well it is for thofe Printers who are not under the neceffity of being retrained in this refpedt fome by choice will not have the beft even when needed, and others for reafons, too common in every flation of life, rnuft take what materials they can get.

Note, As the above is only afummary, or elementary •view of colours &c. a plan of a table for fixing pro- portions andfhades to certain circumjianccs, is offered further on. For conveying thefe mixtures to the cloth various articles are neceflary to be ufed according to certain circumflances ; thefe r Of Colour - Making* vehicles are gums and partes (22); parte being of a more compact confiftency than gum di- luted, is ufed when lines or fine bodies or rtiades are required to be accurately exprefTed ; diluted gum is more ufed in conveying folid bodies, in which no great accuracy of rtiape is required. Of gums, tragacanth has feveral advantages, and if properly managed, would diftribute as well as tho arabic, but this article as well as the oak- gall is not always made the moll of. Lampblack(23), Brazil, &c. are necertary to deepen the colour of thofe mixtures, which would otherwife be too pale for printing, in fome cafes. (22) Pafter arc made from flour and {larch, and thofe articles as well as gums mould be of the pureftkind, when ufed as vehicles for carrying the colour.— Gums fhould be tried that ro faline quality has been incoTporaed with them by their having been before in a liquid ftate by any accident, particularly at fea. .

It is therefore firft obferved, that as goods ap- propriated for printing, though having under- gone the proceiles in ufe among whitfterers, or bleachers by profeffion, may neverthelefs con- tract in the courfe of their removal from one place to another, foulnefTes of various kinds : they are in general foaked or fteeped in water, that any loofe dirt may be removed ; but there may be foulnefTes which, water, only will not remove, of courfe fomething more penetrating mull be applied ; if am be ufed, it is prefumed fome umStuous fubftance is to be removed, which the am efleas ; but as the earth of the afh is fup- pofed to be left in the cloth, which water will not eafily remove, an acid is to be applied for that pur- pofe, or foav.times to anfvverfor aming, and the cloth thus (after the ufual procefles of planking, &c.) is rendered as pure and white as poffible. Here then commences the colour-makers im- mediate concern, and confequently the confidera- tions refpeaing it, of which, it need hardly be faid, the firft is that of the nature or properties of thofe fubftances that are requilite to form a bafis for the colour, chiefly in refped to the" re- lation It Of Colour -moVing. lationthey hold with each other in view of pro- ducing certain effects, according to the principles as eftablimed by nature, which principles in the firft cafe are applicable only to chemical experi- ments (as exhibited in the tables of affinities and the rules immediately preceding them) but in ad- vancing a ftep further, that knowledge mull be confidered as furnifhing us with means of turn- ing thofe experiments to advantage ; therefore a colour maker when furrounded with his drugs &c. mould look upon every article as an inftru- rnent in his hands, that ought not to be employed in vain; but this knowledge, to its proper extent (fo rarely to be met with) is not to be acquired merely from felf experience or the experience of others, and not only that fuch ingredients mixed or applied in fuch a mannej will produce fuch effects, but why and upon what principle it is e- ftablimed, and by what laws it is governed :here is the fpring that mould give motion to this de- partment ; here is the bafis on which the practice ihould be erectec! and diffufe itfelf ; and here originates the grand fource of a colour-maker's pra&ice, namely, the knowledge of the laws of affinities, and the certain efle&s of combinations, previous to the adding of certain fubftances to each other: for in every mixture that can poffi- bly be made, invariable effe&s according to thofe rules will naturally follow. 2MB Of Colour - Making. - Thus beginning with the principal articles in a colour-maker's province (fee note 39 at the end of copper-work) namely, falts or aftringents; (fee note below) it is neceffary to know, according to thofe rules eirablifhed by nature, how each fpecies af- fects any fubftance it may be offered to, and how it is affe6tcd in return ; for all fubftances mixed with others of different qualities, mult caufea change in fome refpect or other, according to the fundamental principles as exhibited in the be- ginning of the compendium of chemlfiry, {fee rule 3) and this knowledge (it is again faid) is the proper foundation or fupport of the practice of colour-making. id, Of Articles that procure from various Subftances their colouring Properties.

Lime has the property of uniting two of the greatefr, oppofites in nature, Salts and Earths ; it is foluble in water, by means of fire ; but the air renders it indiffoluble again ; thus it is capable of forming an unalterable cement when united with other matters ; but allum, as above-faid, has a property beyond, which is that of attracting certain colouring particles (27): nitre, marine fait, fal ammoniac, facrum faturni, and tartar, are, ftridtly fpeaking, only alterants, by chang- ing the red to a crimfon, a bloffbm, a pink, &c. Neutral falts with a metallic bans, rather give ftrength to the colour, than folidity in rcfpect to its fixity, for every colouring fubftance will vary -its fliade, according to the nature of the earth that attracts its particles : Two neutrals, Copperas and Roman vitriol,with metallic bafes, are in common ufe, oweing to their afkringent quality being in union with their alterative principle.

The caufe of rottennefs, attributed generally to the copperas, ufed in procuring black, is owing to the earth of iron (whero it is ufed) not being feparated from the folution, and when faid to be rotten from copperas, it is from the grofs particles not finding eafy admiifion into the pores; hence they in a man- ner burft open their enclofures, tearing of courfe, the parts that refift.— See iron liquor further on.

Of Articles containing COLOURING Properties. Various fuppofitions refpefting the fixity of colours by the ufe of aftringents have been men- tioned, though (as intimated Note 29 in copper- work) the theory generally adopted is conteited; and it may here be added, that Mr. Macquer likewife contefts it, he however obferves, that when the earth of allum, after being conveyed to the cloth, is moiftened, it imbibes the colour- ing particles of the bodies it meets with, though the caufc of the attraction is unknown (31), (fee ■ Ml~ ■ ■■ 11 - 1 — — M-i— j.-j 1 r ~ - -- " ' ' "" and if inclined to it, fufficient quantities of fuch articles are not to be procured till cultivated for fuch purpofes. — Sec note 42.

As lakes are caufed by the combination of one fubftance with another, upon a principle fimilar to what is above alluded, it will be here juft obferved as an example, that if a decoction of turmeric or madder, be made in a watery folution of fixed alkali and a proper quantity of folution of allum be added, the yellow or red particles will fublide ; but at the fame time the acid of the allum being abforbed by the alkaline falts, the earth of the allum likewife fublides and dilutes and likewife brightens the co- lour, the caufe of this operation is however al- lowed to be not fully known.

From animal juices colouring fubftances are rarely obtained .* and could more be procured, it would be only going a further way about, as animal juices are derived from vegetable fubftances. As the merely hmple juices or fluids of animals and vegetables, rarely furnifh materials for durable colours; and minerals, on account of their drynefs are incapable of being attracted by aftringents, we inuft feek thofe fubftances whofe principles form, or help to form that unctuous and phlo- giftic gluten or cement which is the caufe of permanency; and of thefe the moll able to impart their colour are, kermes, cochineal, gumlac(36), madder, weld, &c. being both gnmmous and refinous, though in different degrees, or in ether words pofTefTmg that phlogiftic or inflammable property refulting from the union of oils, falts, and earths, on the various combinations of which, colour (as repeatedly faid) depends, and which exhibit themfelves when attracted by the application of proper afiringents.

Yellows are to be procured from moft leaves, barks, and woods, that on chewing difcover an aftringent tafte, if treated in the fame manner as weld; for the colours of molt yellow flowers are durable, and are little affected by acids or alkalies, but other coloured flowers, as well as juices of plants, are rarely found to poffefs any perma- nently tingeing qualities, according to the ex- periments pradtifed in common. RefpecYing the general method of impart- ing permanent colour, the principle of the pro- cefs is but fimple, (fee note 39 in copper- work) faline fubftances being (as faid before) the chief means with which we are acquainted j thus, it may be obferved, though a watery infufion of madder and other articles, w T ill impart a tinge, yet warning will eafily remove it ; but that is not the cafe if the cloth have a faline article previ- oufly applied to it ; there is however an excep- tion to this rule in indigo, which it is difficult to diflblve s Of Colour -making-. iliilblve {3) except by alkalies, oil of vitriol, orpiment, or combinations of orpiment with fulphur.

Proceeding further in the difcuflion o colouring qualities, it may be obferved, as the fixity of colours produced by different fubftances being mixed together,is proportionate to the power of fuch fubftances to withftand the weather, it would feem as if there were fome method to de- termine on their permanency, fince it appears that the nitrous acid in general tends to heighten red colours, the vitriolic to crimfon them, the marine to dull them, and alkalies to deepen them, (38) for, in this cafe, the colour produced by the nitrous acid, can remain no longer, when expofed to the air, than the fpirit of nitre itfelf, becaufe the nitre being drawn into the air, the colour muft fade ; and the difpofition of colour to fade, mufl be in proportion to the permanency of the fubflanccs that produce them; colour, in this fenfe, being only colour as it is in poflcflion of fome fubftance to withold it ; (39) but (38) In drying plants between iheets of paper, the paper is at laft tinged with colour ; this is fup- pofed to be occafioned by the allurn ufed in mak» ing it — By rubbing a plant on blue paper, if acid, it turns the paper red, but green, if alkaline.

It may be faid too, that in all compofi- tions there is the bafis which is fuppofed to be un- alterable in its effects ; other matters may be'added • but from them, certain modifications only, will be the refult ; hence this principle mould be much thought of, that the more fimple the bafis of the compofition h, the more eafy is a variation to be made ; and, in a contrary light, if what is fuppofed to be the bafrs, be compounded ; as for inilancc,in a blue and yellow put together to make a green, it is highly probable that what may be added will difagree with either the blue or yellow more than the* other,, and if more articles are added, the left certainty there can be of an effecl.

If vitriolated tartar, or Glauber's fait, dif- folved in water, be mixed with another folution con- fiding of calcareous earth, filver, mercury, lead, or tin, diflblved in the nitrous or marine acid?, the vitriolic acid will leave the fixed alkali with which it was combined, and unite with the calcareous earth, or the metal, and fall to the bottom.

Two pieces are to be printed with the fame colour, but with different prints; one print fine and the other coarfe, or with folids in it; therefore very probably that with the folids will be more impreffed in the cloth than the other, from its being deemed ncceffary to hit it more forcibly ; hence though the colour for both pieces come the fame from the colotfr- houfe, the effedt. may be different in the fhade of the colour : and in printing doppies it fome- times happens, that if a piece is not thoroughly dry, or if it be of a flimfy nature, the colour may be forced through, (47) while another more (47) Here it might feem to many, that cloth being- fo thin, this is a matter of indifference, but when it is confidcred, that the aftringent and colouring atoms are fo fmall, that a great number piled on each other would bear no proportion to the in : Of Colour -making. more dry, or of a firmer texture, will refill that circumflance ; therefore here again, though the fame colour is ufed for both pieces, yet one will have a paler or more wafliy appearance than the other ; and the moil ignorant Printer knows, that if a {hop be not kept warm, it is dangerous almoft to work any colour ; (fee note 34) and that it is always bell to finiili a piece, though the colour may be ufed out of the fame pan"; a difference may arife too from colour being old or frefh ; and to all thefe may be added the chance of fome part being performed with foul brumes or fieves, worked on hard blankets, or from coarfe fieves, lying on very lliff gum or paile ; or fome pieces may be worked with the iirfl colour with- out the thicknefs of the cloth (fomethinr fimilar to the microfcope difcovering- thoufands of animals in the breadth of an hair) it mull then appear othervvife and rauft accordingly be of fome importance whe- ther they are only on the fuperrices of it, within the body, or whether they are forced quite through ; in the firil cafe the tinge can be but weak, in the fecond it is likely to be more effective, but in the lall the atoms mull be too much difperfed for pro- curing that clofely conne&ed body or mafs of co- louring particles which is requifite. . 11 ,. .

As to thofe who with fuch a complex bu- finefs on their hands without either means or capa- city, or who under the infatuated idea of being matters, have precipitated themfelves into it with- out proper fupport, they are really to be pitied, for when railing fupplies become fo preffing, that (as in the memorable failure of Mofney-Houfe dwelt on in another place) the bufinefs in the operative part is but a fecondary concern, any one may judge how confufedly it mull be profecuted or difcreditably terminated. Remarks like thefe may appear invidious, but if they caufe any who are inclined to commence callico printers to reflctf fufficiently on the nature of the bufinefe, the writer is not apprehenfive of meeting with cenfure for fuch freedom, being cer- tain that he* has done a real fervice. He likewife cannot here forbear giving a hint of advice to the Printer, and he will add, that it is of confequence to a Draper to attend to it ; for unlefs a Printer can evince his capability of executing work properly, the Draper has a chance of lofmg, ? * . as \ Of Colour - Making, could be fpecified would be reconcileable to an- ther's requifite mode of practice. It may how- ever be fuggefted, that if a Colour-maker would arrange as it is prefumed to be more acceptable to have goods returned well executed, than to have to lay da- mages as fome compenfation for bad work ; befides, a Draper mould not only inform himfelf whether a printer can execute what he undertakes, but whe- ther he can do it in proper time (chemical and general patterns are not here included.) A cir- cumftance of this nature not being attended to, was the fubverfion (or at leaft forwarded it) of a confiderable printing-ground at Old Ford (Lay and Adams) a few years back, the Principal having undertaken late in the Autumn, to execute for the Spring, a confiderable number of very elaborate patterns j but though every nerve was drained, the effort was in vain, and as well as the Printer being overturned, the Draper muft have fufFered. What helped to raife the names of Newton and Kilburn to fuch distinction, was in their outfet being forward with their work, as well as excellent in general in the execution ; and much was it re- gretted then, by the lovers of excellency, when the firm was diffolved ; though the exertions and productions of each fince that circumftance, have been ftill fo refpe&able, thatCallico-printing in En- gland * Of Colour - Making, arrange the different courfes of operation his colour has to go through, * in regard to the tex- ture of the cloth, ftate of the prints and grounds, blankets and fieves, thickning, preiTure, &c. the operations might be reduced into fome fyftem be- yond what is at prefent done,which is rarely more than proportioning the ingredients for fine or ftout cloths, blotches, and fine prints and ground; ; tor certain it mint be that according to the pro- portions or manner in which the iron liquor, allum, ccc, is imbibed by the cloth, whether from P3 the gland may be laid to owe its revival and prefent credit to their efforts ; 2 or 3 other Printers arc certainly entitled to commendation ; but not {landing fo forward in the articles of novelty and tafle in deiign, or brilliancy in execution; they are not particularly pointed to. * Even in nearly the laftprocefs, that of whitening printed goods, a carelefs Fieldman may render all that has been done abortive, efpecially in ftrong fun-fhiny weather attended with a drying wind, if goods are watered in patches, or naffer too long an interval between watering : the mifchief will be flill more obvious, if pale colour work, fuch as lay- lock, bloffom, or other pale blotch grounds, are thus treated— Sec the article Grafs Bleaching. ,* Of Colour - Afaklng. the manner of their being mixed, or their treat- ment in the printing mop, the colouring drugs can only impart therr qualities towards giving the ■ effect that is defired.

As to certain projects (fome already fpoken of, fee note 42 and text above it, on the ideal hope of uniting the aftringent and colouring qualities in the fame article ) among which at prefent is the idea of raifing feveral colours at once, by the agency of a certain weed, though the necefTary procefs precludes proper permanency, the writer muft ftill re-iterate the propriety of firft attain- ing more certainty in the prefent practice, as that would lay a proper bafis for improvement (See Preliminary Suggeftions, notes 39, 49, 50 and 52 to this fection, and eli'ewhere ) And may it be here faid to fome (even to Chymifts in their Laboratories) who hitting on this or that ting- ing article, conclude they have gained the point; that in refpect to Callico -Printing, it is but advancing one ftep towards it (in Dyeing it may probably be fufficient) for, if the writer may fo fpeak, till the tinging article, according to Hydro- ftatic laws, is of equal fpecific gravity with the buoyant one (the thiekning) it muft neceffarily either link, float at the top, or fly off in fume or vapour, by the attraction of certain fubftances or qualities of the atmofphere, as in the inftance of pencilling blue.* As to other certain impediments, thofe only who are well acquainted with the bufinefs, can have a conception of them. It may neverthelefs be faid, in refped to Printing in common, that on the Continent Principals being more arbitrary, as well as more philofophical than thofe here, are abler to manage and direct workmen than can be done here : thus it is ufual there for one workman to put in the Black, another the Red, and fo on : but dare the firft Printer we have at- tempt fuch a mode, proper as it moft afluredly is ? no, on the contrary, men here are fo much mafters, that too often regularity muft ftoop to confufion, propriety to abfurdity ; and judg- ment itfelf to downright ignorance ! ! !

Concerning permanent BLACK and PURPLE. Iron-liquor, or calxjof iron diflblved in vine- gar, from whatever liquor procured, is the agent for obtaining permanent black from madder; and by judicions tempering with water forms purples and lay locks;* the black itfelf being only a deep purple : — With logwood a lefs permanent black or purple, of a bluim dulkier hue is ob- tainable. With weld and other yellow colour- ing fubilances, the hue is brown. When added to the red colour, or more properly the al u mi- nous folution, thenchocolate^pompadour, blofTom &c. are formed in the madder copper, according to the proportions of mixture, from the colour- ing matter being taken in combination by both the calx of iron and the earth of allum at the fame time. Some think the additament of alder bark, or decoctions of other aftringents might help the iron liquor in certain cafes, as when newly pre- pared or procured by a weak acid. Of the tar acid iron liquor, or the chalybeat one, the writer will fay little ; the expedition of procuring either may have its advantages, but much * Ufing pafle or gum occafionally as thicknings, or vehicles for carrying them to the cloth. Of Colour-making, much caution is needful before a courfe of work is attempted with them, vmlefs the manufacturers are of undeniable repute : for though a deal may be faid of the acid employed and of its immediate operation on the previoufly prepared calx, yet every printer, as already obferved, is fully fenfible of the value of good old iron liquor, and of courfe preferves it for particular purpofes. As to what is faid by fome of the acid pro- cured from cyder, perry, &c. and nfing fteel filings, it (till is but vinegar, and the fteel muft be converted into a calx before a drop of iron liquor can be formed. Hence the only fuperiority it can hoaft over any other, is in its being fre-er in its fir ft ft ages of manufacturing from ufelefs or injurious matters ; and from the iron being very minutely divided, and, of courfe, prefenting more furfaces to the action of the acid, the folu- tion is more expeditioufly performed. It may not be irrelavent to add, that the more concentrated the vinegar, or the nearer it ap- proaches to diftilled or radical vinegar (58) it § 3 ma v- (58) Vinegar diftilled from verdigreafe ; but to fpeak of this as well as other articles, new terms of fc. - Of Colt cur-makingi may be proportionably effective, both in refpeft to power and expedition : and fmall beer or weak wines are known to give of little power. As to the age of common iron liquor, that is, fuch as is procured in the old way, it is indifputable that the particles of iron or its calx are found to caufe a finer colour and of being more uni- formly difperfed, however lowered the mixture may be, than in the new iron liquors. In facl, it is this perfect faturation, and the cafe is ap- plicable to aluminous and other folutions, that denotes its excellency. And this is no where more evident (as well as with the red colour) than in the charging of copper-plates, where the engraving is very fine : for it is certain that the colour made at different grounds by different operators, will not fuit the fame engraving. Other cir- cumftances to be fure may intervene, yet the above ef doctrine mud be ufed, at prefent deemed incom- patible As Tinegar diffolves iron (lowly, and only then with accefs of air, the tar acid, or more properly the acid of wood, has been lately much ufed and ^tolled, being applied immediately to the cake. Of Colour-making, above is certainly one worth attending to (59) But in this inftance it may be faid in one cafe, that, by the particles of iron being more faturated with the liquor, and in the other by the earth of allum being completely faturated with the vine- gar, of courfe, both the calx of iron and the earth of allum are carried with their folvents into the fin eft interfaces. N. B. With blue colour for copper-plate piinting the difficulty is greater!: : hence the colour here cannot be too pure and free from adventitious matters, not only for filling the in- terftices, but alfo for the fake of the doctor or clearer. Perhaps what tearers call vittry colour, or that which in boiling, or other fUges of pre- paring black, appears frothy, fcummy, lumpy, &c. is from the iron liquor not being free from plumbago (which is a combination of the bafe of fixed (eg) The perfect digeltiou of gails and other af- tringents; or their faturation with their folvents, is as fully needful in certain courfes ; for in both cafes, the extreme divifion of the particles produ- ces the bsfteiFe&s. -m 1 Of Colour-making, fixed air or pure charcoal with iron. Of which much might be faid, .but for reafons juft given, it is waved at prefent, except that being black lead, it is infoluble in acids. Tn the copper a decompofition of the liquor takes place either by attridibn (note 28) or by an attraaion of the colouring matter of the madder, or elfe by an attraction of the cloth itfelf (60) to the calx held in union by the vinegar: which in this cafe is fimilar to the earth of allum in combination with vinegar. The writer will not yet pretend to fay how the foxing of the purples (a common phrafe) may be avoided with little trouble, but he obferves as it is fure to take place if the water be heated to a certain degree, it renders the purple an iron mould, or a metallic ftain ; the comburtion having decompofed it, and feperated the colour- ing matter from it. For here be it obferved that the purple on the cloth is a compound matter, formed (60) The lateft modern opinion is that the cloth itfelf in the copper undergoc. a partial fo- lution. Of Colour -making. formed of the calx of iron and the colouring matter of the madder. Why the red is not fo eafily 'decompofed is from the clofer attraction of the colouring mat- ter of the madder with the earth of allum : and it has been obferved, the black and consequently the purple is deemed only a depofiticn of the calx; befides, as a proof of it, it is known that the deeper the purple, the eafier it is afFedted, which only feems fo from there being more fubftance to be acted on. In maddering if the heat be too intenfe, a fimilar circuniflance happens, that is, a brownefs en- fues, fo likewife does it in mere welding ; only in the firft cafe the colouring fubftance already on the cloth is changed, but here the colouring matter of the weld in the copper is changed, combuftion being the caulc of both. Note An iron liquor, not generally known, is obtainable from a decoction of rice in which red hot iron is thrown ; it is then to be added to a certain quantity of vinegar in which red hot iron has likewife been thrown. Concerning Of Colour-making, Concerning permanent RED.

Woad however is the clofefr. of kin to indigo; in fadt, indigo is obtainable from it. (71) The (70) Pruffian blue is iron, in combination with pruffic acid, which acid has precipitated it from its folution. The acid is prepared by calcining animal matters (generally oxes blood) with alkali. The common fclution of Pruffian blue is by folution of tin or marine acid ; fomething of which kind wat lately hawked among London printers as a blue to print with, and called the true Switzerland blue. But the whole proved rather an abortion, — See further on, refpe&ing metallic calces and precipitates. (71) By the agency of lime, or by adding pur« alkali to the woad, when fermented with water.

The appearance that indigo exhibits (note 37) in folution, is its becoming green, or {hewing a green furface with lime, alkali or certain calces : The colouring matter here evidently flies off, and until that takes place it is infoluble. (*) The copperas and orpiment are fuppofed to do this from certain powers of affinity or attraction. 1 he bei methods for forming blue vats, accord- to the moft refpe&able French chyraifts and dyers, are ift, By macerating the indigp in a ftrong ley, then grinding it, adding lime and water to it, raking it when the lime is flacked, and then adding green copperas or orpiment. — After this, the indigo (previoufly ground) is to be added, raked and then fufferedto reft as ufual. 2nd, method, being more fimple, is by adding certain proportions of indigo, green copperas, 'ime and water, and this compofition, after raking, is fit for dyeing in a few hours.

Tofpeakofthe Saxon blue is hardly worth while, it is fo very fugitive, being a mere folu- tion (if it can be called fuch) of indigo in Vitriolic acid. If this, however, be added to a proper folution of indigo, a green may be pro- cured ; and if the acid be rather predominant, i* increafes the intenfity. In blue dipping, if the cloth appear clean and white, as in other cafes mentioned under the fecti- on of copperwork, the preparation is generally difpenfed with, on a prefumption thecloth has no oilinefs in it ; but this does not always feem to be the cafe, and the writer cannot think fubordi- nate blue dippers, printers, and cylinder workers, are always in fault, when ftormont and other clofe work appears uneven. And he knows, that faults are fewer where preparation is more indifcrimi- nate. Even for common chemical work, it may be more needful than perhaps many think ; for it is certain, that if the afhing be not properly or Cufficiently performed, the cloth will turn brown in time : and this, by the way, may account for the brownnefs that is obferved to take place in cloth where Of Colour-making. where chemical colours are brought up in lime water, unlefs it be fuppofed that the lime may de- pofit fom,e of its earth, orfomefubftance that may. be in union with it, (as lime itfelf is earth) which in time caufes that brownnefs.

But, while praife is bellowed where merited, it is here freely faid, may thofe pra&ices juit fpo&en to this object ; for as it was, the Principals feemed latterly to have loft fight of Callico Printing, among their various fpeculative practices ; indeed one of them (Smith) generally had political bufiuefs enough onhis hands; (his interference refpeding the Callico- Printers' bill, is as well remembered, as his argu- mentative powers were acknowledged) but with what propriety Printers, Manufacturers and Tradefmer*. in various and extenfive dealings and connexions, plunge into the abyfs of politics, beyond what con- cerns their immediate vocations, is not attempted here to decide ; as it may be partly gathered from the rebuff Lord Thurlowe gave Jonah Wedgwood, in faying, whatever he might be as a Potter, he was an indifferent politician. Of the pamphlet above alluded to, it may be ob- ferved, that moft men in bufinefs, in what they write, naturally have an eye to their immediate vo- cations and interefts : thus Mr. P e dwells upon the increafe of manufacture, but paffes over thofe pra&ices that, however they overload the market, leffen the value of commodities, and is filcnt about that refpeftability which keeps up the fpirit of any profeffi^n, or that is a proper inducement for genius to exert itfelf • for of the vail quantities he himfelf A Retrefpeflj &c. fpoken of, (too notorious to need fpecifying,) be ever ftigmatized, difcountenanced, and repro- QJ> bated himfelf has thrown into the market, a great part is well known to have cod him little on the fcore of defign and execution, the fale at the fame time being undoubted.* And the writer cannot but lament, that while the Minifter in the late difplay of the profperous ftate of the nation, on opening the Budget for 1790, was attributing it to the increafe of manufactures, and the confurnption of article*, he was filent on the probability of fome of the manufactories ^oing to decay at the feme time, as he only regulated his decisions by the. ftate of the excife and cuftomsj thus to come home to the lubjeft, he can only eft; mate the profperity. of the Callico-printing bufineis by the entries, which in this cafe is the fame, whether work fells at iod. per yard, or 10s.

And, here it is repeated, is the overfight in the Pamphlet, in no notice' being taken of that refpec- tability which ought to be preferred in* any bufi- Jiefs, that by proper means the market be kept open, and that one Manufacturer ihould not, by illaudable practices, render his profeffion, and what he produces, of fuch little value, that at lait it is neither beneficial nor creditable in any refpecl: whatever. Of the point chiefly dwelt on in the above-men- tioned pamphlet, it may be juft remarked, that national credit, like that of tradefmen, can only reach a certain height without breaking; and high as England is now in political health, or firm in constitution, who can fay how long fhe may remain fo, or that even the means employed to keep her fo may not defeat the intent, or that another Gibbon/ feme centuries hencej may not attempt to account for .. •_ f .

(13) As there always were, and always will be, men who .bid defiance to legal obligations, as well as mere moral ones, thofe piratical practices, un- warrantable in intention, difgraceful in execution, and deftructive in their tendency, will probably never be Hopped ; and the check they have re- ceived, (fee note 9) is far from remedying the evil, for an elaborate pattern of the fame Parties was foon after imitated.— See note 14, and the General Reflections, &c.

Sheer necefllty may perhaps plead for indulgence, and on that fcore pity is due rather than indignation, and pity is be- flowed. *viour of the Profecutor, on the conciliating contpromife that pre feV. tiering operations cheap, eafy, and expeditious, are the only points proper to be deemed as aiming at improvements, from being of immediate pecunr- ary confideration (9) befides, it is a very difficult matter to get journeymen out of an old track. In (9) This it is granted is Co in this icn r c 9 but then the coniequence is lowering the price of the articles which ( as often particularly dwelt on ) ftrikes at the very root of that refpectability which only can render Caliico-printing more worth the notice of the opulent and famionablc.* But according to the writer's idea of improve- ment, totally the reverie of that mentioned above, the confequences would be a greater demand for works of genius, an increafe of mechanical and manual operation, and a more extenfive requeft for utenhls, drugs, &c. with a furhcient inducement for men of fcientific knowled e, to make proper experiments on articles not in common ufe, at lead in printing (fee the notes at the end of the account of Colouring Drugs, and the end of theRetrofpc6t) for thus it was, by calling forth the powers of Phi- lofophy and Genius, in conjunction with the know- ledge of the mere Practitioner, that the illuftrious Patron * This dejiruftivc principle^ the writer is forry to fay, feems to crujh any further progtefs in that elegant improve* merit j copper-plate printing.— See note 10 totbtretrofpefl. General Reflexions, &c. In another light, a great hindrance lays in the lukewarmnefs with which Government ilftens to propofals of countenancing anyart, unlefs they tend to an immediate increafe of revenue, or at leaft do not interrupt the channels of it. From thefe considerations, enthufiaftlc as the writer may be in his wijflbes for the exaltation of the profeffion in which he has a concern, it is feared, that what has hsen advanced mull remain an ideal profpec"l little likely ever to be fubflan- tiatedj or be coniidered as an airy excurfion r pro- ductive only of a deluiive hope, or an imaginary advantage ; and as thoie who arc particularly cramped and injured by piratical and debating practices, can do little more than complain, fo in refpeel to improvement, whatever may be faid for bringing the ufual courfes of operation into more certainty of effect, the bufmefs muft neverthelefs remain in this retrained and im- perfect flate ; which Uriel ly fpeaking, is, that two Patron and aggrandizer of the arts, above fpoken of, fo advanced the art of dyeing, as to give France that pre-eminence in it. which file even retains f this day. A General Re/IeeJions, &c. two or three can command a price to enable them to execute decent work (which is only fo in a comparative view,) and the reft fill the market as well as they are able ; and thus, fea- fon after feafon, Calico Printing retains the fame complex Ion, only the features are now and then a little altered, and frequently diftorted. However, according to the mode the writer affects of biinging what he advances to a point, * fo here it may be faid that The improvement of any profeflion depends on a knowledge of its principles, and the appli- cation of them to* practice. Increafing the refpectability of any profeflion increafes its intrinfic value. Under-working, under-felling, and piratical practices, are, on the contrary, deftru&ive, or fubverfive of it ; and this confideration compri- zes, the ufual confequenos of adopting cheap and expeditious modes of operation.
