 Sir: 1 have the honor to submit herewith the manuscript of a rei)ort 
 on the culture of hemp in Europe, which has beeu prepared in order 
 to acquaint the hemp growers of this country with the foreign prac- 
 tices by which high grade imported hemps are produced. 
 
 The growth of a grade of American hemp that will sell for (> to 8 
 cents per ])ound, instead of 3 to 3^ cents per pound, as at the present 
 time, means that our farmers must follow more closely the careful prac- 
 tices of Europe, and especially that they must adopt water retting in 
 jdace of the present practice of dew retting, which gives a fiber dark in 
 color and uneven in quality. A careful consideration of the practices 
 of Italy and France as set forth in this report will materially nid those 
 who desire to change their product from the cheaper dark hemps, for 
 which there is small demand, to the higher-priced light liemi)s, which 
 will compete with the imported commodity. 
 
 I wish especially to call attention to the report, gi^■en herein, of 
 United States Consular Agent Gardini, on the growth of Bologna and 
 Ferrara hem]), and to state that it has beeu impossible, until recently, 
 for the Department to secure any information regarding the growth of 
 Italian henq), which is recognized as tbe highest grade of hemp that 
 comes to this country. The present widespread interest in hemp cul- 
 ture in the Southern States and in States west of the Mississippi 
 makes the publication of this material at this time most desirable.

CULTURE OF HEMP IN EUROPE. 
 
 INTRODUCTORY. 
 
 The cnltivation of hemp in the United States is a very old industry, 
 and at one period in our Ijistory was a very large one, the annual pro- 
 duction in 1859 reaching ii total of nearly 75,000 tons. But there has 
 been a decline since this point of highest production was reached. In 
 1870 the annnal production for the entire country had fallen to a point 
 as low as 5,000 tons, then rising to about 12,000 tons ; two or three years 
 ago it again fell to 5,000 tons, but in view of the recent widespread 
 interest in the growth of the plant, production is now increasing. 
 
 Many good reasons have been cited for this decline, which need not 
 be enumerated here, further than to state that serious injury was done 
 to the industry at the time when Jute began to be used for bagging in 
 lieu of tiax and hemp, about 1872. For a long time tlie average annual 
 production of the country amounted to about 12,000 tons, but with the 
 lowering of prices, and with a failing demand for the kind of hemp 
 that was grown, the subsequent decline to 5,000 tons was a most nat- 
 ural sequence. The low prices that have prevailed for sisal and manila 
 fibers during the past few years have been factors in this decline, 
 though the fact may be stated differently. The kind of hemp grown 
 was so low in grade that it wns simply crowded to the wall by better 
 fibers. 
 
 Within two or three years, since the Office of Fiber Investigations 
 has been advocating better methods of culture, and since California 
 and the South have become interested in the production of hemp, the 
 reaction has set in ; there has been an effort to improve quality, with 
 the result that fiber worth 6 and 8 cents per pound has recently been 
 sent to the Eastern markets, and now the interest in hemp culture is 
 extending in many parts of the country where hitherto it was un- 
 known. 
 
 The coarse hemp of Kentucky and Illinois, P^-cent fiber, if it may 
 be so referred to, is dew retted, dark in color, not carefully prepared, 
 and fit only for the commonest uses in manufacture. For this kind of 
 hemp there is now a very small demand. The imported hemp, the 
 Italian particularly, is water retted, light in color, some of it almost 
 white, is carefully prepared, and the best of it cai)able of use in some 
 of the manufactures for which fine flax is employed. This may be 
 termed 8 cent hemp, and it is the kind of hemp that American growers 
 should produce, and for whicli there is a large demand.

lu a recent report issued from this office ^ detailed statemeuts are 
 made regarding' the cultivation of hemp in the United States, but in 
 view of the i)resent widespread interest in the subject, and the neces- 
 sity for improving the quality of liber produced by better methods of 
 culture and preparation, it is essential that our farmers should know 
 something of the methods employed in countries wliere the best hemp 
 is grown. To meet this necessity the present report has been jn-epared, 
 and the author presents an account of the practices followed in France 
 and Italy, because the hemp of these countries is the finest grown, 
 although it should be stated that French hemp is lai'gely consumed at 
 home and rarely finds its way to the United States. 
 
 There are other imported hemps, such as the Russian and the Hun- 
 garian, the former, while lower in grade than either the French or the 
 Italian, being imported into this country in considerable quantity and 
 occupying a place in grade between the American and the Italian. 
 
 This oflice has examined many specimens of native hemp during tln^ 
 past season, submitted for expert opinion or otherwise; some of them 
 were the results of first experiments in the direction of better culture, 
 but all gave substantial evidence of improvement in quality, while a 
 few specimens show('<l that it may be possible in the future to even 
 compete with the Italian. 
 
 KINDS OF HEMP GROWN. 
 
 The native home of hemp, known botanically as (Uiminlm safira, is 
 that part of Asia consisting of India and Persia, but it is now in gen- 
 eral cultivation in teinperate and tropical climes throughout the world. 
 
 Several varieties are recognized in cultivation in this country, that 
 cultivated in Kentucky, and having a hollow stem, being the most 
 common. China hemp, with slender stems growing very erect, has a 
 wide range of culture. Smyrna hemp is adapted to cultivation over a 
 still wider range, and a variety is beginning to be cultivated in Cali- 
 fornia known as Japanes<' hemp, but which is doubtless identical with 
 China hemp. In Europe five varieties are cultivated, which are enumer- 
 ated as follows: The common hemp, grown largely in France and gen- 
 erally in Europe outside of Italy, growing to a height of 5 to 7 feet; 
 Bologna hemp, known in France as Piedmontese hem]), or Great hemp, 
 an Italian variety averaging 12 feet in heigiit; Chinese hemp, known 
 in Europe since 184(1, and said to have been imi)orted by Signor Itier;^ 
 the Cannapa pia-oht, or snuill hemp of Italy, with a reddish stalk, which 
 is found in the valley of the Arno and around Tuscany; and the Ara- 
 bian hemp, known as Takrousi, a short species cultivated for its resin- 
 ous principle, from which hasheesh is derived. 
 
 'Report No. S, Fiber Investigations series, on the culture of Ht>mp and .Tntt- in the 
 United States. 
 
 -It is stated that in Ali^icrs tliis hemp has been grown to a licinlii ot 20 tcct, .ind 
 that its fiber is remarliablv fine and wonderfully elastic. 
 
A PLANT OF UNIVERSAL GROWTH. 
 
 Tlie culture is very old in Cbiua and Japan, the lienip of the latter 
 country being remarkably fine and strong. It grows throughout India, 
 ascending the Himalayas even to 10,000 feet elevation. It flourishes in 
 tropical Africa on both the east and west coasts, and is found to some 
 extent in the interior. It has been naturalized in portions of Australia, 
 and thrives in several South American countries, while in Xorth ^Vmer- 
 ica it can be grown from the Gulf to Canada and from the Atlantic to 
 the Pacific. 
 
 In Euroi)e the culture is confined chiefly to France, Italy, Germany, 
 Hungary, and central and southern Russia, though it grows in Holland 
 and Belgium and has been cultivated in parts of (rreat Britain and 
 in Sweden. The Italian culture is largely confined at the present time 
 to the provinces of Bologna and Ferrara, the French to the northwest- 
 ern districts, or Breton, France, while the chief producing districts of 
 Russia are Orel, Koorsk, and Smolensk, and the Polish provinces. The 
 plains of Hungary are said to be peculiarly adapted to tlie culture, and 
 the Hungarian product is stio:ig and good. As to the mere matter of 
 growth, there is hardly a locality in Europe where the plant may not be 
 cultivated; and the same holds good in the [Tnited States, where in 
 many sections it has escaped from cultivation and masquerades as a 
 native weed, all of which tends to prove that hemp is a plant of easy 
 growth. 
 
 THE HEMP INDUSTRY IN FRANCE. 
 
 Toward the latter part of Se])tember, ISSO, the author visited the 
 hemp region of western France, spending a week in different localities 
 in the departments of Sarthe and Ille-et-Vilaine, the hemp culture of 
 this country being carried on for the most part in the section of France 
 known as Brittany. 
 
 It Avas interesting to learn that there was a large demand for hemp 
 for spinning purposes, smaller now than formerly, because cotton has 
 come into such universal use, but still enough to make quite an industry 
 in the production of hemp "linen" alone. This manufacture includes 
 shirtings, sheetings, and similar " wliite" goods, canvas, and a number 
 of coarse fabrics w^hich find a ready market. Some of the fabrics 
 examined, which had not been bleached, were creamy in color, atid so 
 firm and durable that one readily understands why they still furnish 
 employment to the Breton peasants in their domestic economy. The 
 larger demand for hemp fiber in this section, however, is for the manufac- 
 ture of cordage, the seat of tin's manufacture, and the seat of the hemp 
 industry as well, being Angers, in the department of Maine-et- Loire. 
 For lack of time Angers was not visited, and it was hardly important 
 that it should have been, as all necessary information could be obtained 
 in the localities tliat were visited. Methods of culture and of handling 
 the product after harvesting are practically the same as were followed 
 
8 
 
 many years ago, a gradual decline in quantity produced being tbe 
 principal change that may be noted in the industry. 
 
 Probably the finest hemp is produced in Italy. The French hemp 
 resembles tliis somewhat in color, both being a creamy yellow and soft 
 and fine. The Kussian and American hemps differ from these, being 
 for the most part dark in color and not so fine in quality, though it is 
 possible to improve the quality by better methods in both countries. 
 While there is room for improvement in our own country, it would seem 
 unnecessary to produce a hemp for spinning into fabrics to compete with 
 ilax raauufuctures when there should be a good home demand for a large 
 quantity of coarse hemp, and the flax industry in the United States 
 needs encouragement for the i)roduction of a grade of fiber for the very 
 fabrics that hemp would enter into. Nevertheless, it is interesting to 
 know how the French hemp is produced, and the main purpose of the 
 investigations was to obtain information in this direction for the benefit 
 of American farmers. 
 
 The prominent departments of France where hemp is cultivated are 
 Maine-et-Loire, Snrthe, Morbihan, Iscre, and Puy-de-Dume. The two 
 varieties cultivated are the common hemp of the country and the Italian 
 hemp, the seed of which is obtained at Piedmont, the chief difference 
 being in the length of the stalk, in slower development, and in its 
 coarser quality, making it better adapted for cordage. 
 
 Climate hns nuich to do with the successful cultivation of this plant, 
 as it makes the best length of stalk, and therefore gives a greater yield 
 of fiber, in those situations where the climate is mild and the atmos- 
 phere humid. Limestone soils or the alluvial soils, as found in the river 
 bottoms, are most congenial to its growth, and as this portion of France 
 is well watered by rivers or smaller streams, the cultivation is quite 
 general along their banks. Such soils in our own country have given 
 the best results. A rotation of (;rops is practiced, hemp alternating 
 with grain crops, although MM. Girardin and l)u Breuil state that it 
 is also allowed to grow continually upon the same land. Regarding 
 this mode of cultivation, they consider that it is not contrary to the 
 law of rotation, as by deej) plowing and the annual use of an abund- 
 ance of fertilizers the ground is kept sufficiently enriched for the 
 demands which are made upon it. If the soil is not sufficiently rich in 
 phosphates or the salts of ])otassium, these must be supplied by the 
 use of lime, marl, ground bone, animal charcoal, or ashes mixed with 
 prejjared animal compost. Even hemp-cake, the leaves of the plant, 
 and the " shive" or "boon," may be returned to the land with benefit. 
 This high fertilizing is necessary, as "the hemp absorbs the equivalent 
 of 1.500 kilos of iertilizers per every liundred kilos of fiber obtained." 
 
 PREPARATION OF THE LAND. 
 
 As in flax culture, a thorough preparation of the seed bed is impor- 
 tant, and the finer and more mellow the ground the better will be the 
 
fiber. The first plowing is done in summer after the harvest of the 
 previous crop, for hemp is not considered an exhaustive crop, and is 
 frequently grown upon the same land for a succession of years. The 
 writer was not able to witness any of the agricultural operations iu 
 this industry, as it was late in the season, but the plowing is thus 
 described : 
 
 The earth is thrown up so as to form two trenches of 0.30 meter 
 (about 1 foot, iu width, letting it fall over a strip of ground likewise 
 of 0.30 meter in width, and which is comjdetely covered by the earth 
 thus thrown up. The heat at this season is sufficient to soon destroy 
 the weeds contained in the earth thus treated. Ten or fifteen days 
 later a roller is passed over the ground to level it, and a portion of the 
 fertilizer is spread; then about 24 hectoliters' of beans are sown to 
 form a green compost. After this a second plowing is given, but in a 
 reverse manner from the first, that is to say, the strips of ground 
 which had been left at the first plowing are now turned over. The 
 roller is again passed over the rough earth and draining ditches are 
 made to prevent any moisture from hindering the plowing, which 
 should terminate the series of operations at the end of autumn. This 
 last tilling is done when the beans are 16 to 18 inches high and before 
 the frost. 
 
 The harrow and roller are used to mellow and com]>act the soil, and 
 small lines of trenches or furrows are dug for drainage purposes, tliese 
 leading into the transverse ditches. These lines are about 10 feet 
 apart. No further preparation is needed until tbe time for sowing the 
 seed. Just before this time arrives the groun<l is worked over to kill 
 the weeds, and is again harrowed. The seed is sown in drills, and 
 covered lightly with a hoe, the soil being pressed down and made com- 
 pact with this implement. The sowing occurs in the north of France 
 about the last of April. The best fertilizers to use in hemp culture are 
 ground bone, animal charcoal, lime, marl, and compost mixed with 
 ashes. It is considered an advantage, likewise, to return to the soil 
 the leaves and woody matter after cleaning, as well as the water in 
 which the stalks were retted, when this is possible. 
 
 (,)TTANTITY OF SEED TO SOAV PER ACRE. 
 
 The best seed conies from Piedmont, and, as it deteriorates rapidly, it 
 is frequently renewed. The closer the plants can be grown the better 
 the fiber, and to this end a large quantity of seed is used. A farmer in 
 Sarthe informed the writer that the usual custom was to sow 00 liters 
 of seed to 44 ares, 40 ares being equal to an acre. This would give as 
 the proper rate to sow about li bushels to the acre, though 4 bushels 
 are sometimes put iu where very flue fiber is desired. Tiie sowing is 
 done about the last of April. 
 
 'The area was not stated, but it is supposed that this quantity was for a hectare, 
 whicla would be equivalent to 2f bushels of beans to tlic acre. 
 
10 
 
 As the seed must be sown quite thickly to produce fine hemp, it 
 deteriorates rapidly aud involves the necessity of iVe(iuently renewing 
 the seed; this causes a considerable expense. In order to retard as 
 much as possible this impairing of the quality, there are a certain 
 number of feet, upon the borders of the field, thinned out, and maize, 
 beet root, etc., sowed, so that the i)lants, being isolated, may acquire a 
 large development and the seeds produce plants which will preserve the 
 proper characteristics of their species. The good seed is of a dark-gray 
 color, glossy and heavy. It preserves its germinating jiower but one 
 year. 
 
 When the ground hardens too rai)idly, after sowing and before the 
 plants have started, straw is sometimes strewn over the field, or the 
 rake used to keep the surface open. 
 
 As in fiax cnltui-e, the crop must be kept free from weeds; all injured 
 plants must be remo\ ed, and it is the custom even to thin out the plants 
 when growing too thickly, as is frecpiently the case from irregular sow- 
 ing. It was learned that 250 plants to a square meter^ of ground is 
 considered the right average when the fiber is grown for cordage; but 
 when produce'1 for fabrics at least 400 plants are allowed to grow in 
 this area. Full details of the manner of harvesting the crop at the 
 farms visited were not obtained, but some facts as to the methods of 
 harvesting are condensed from a French work- furnished the writer by 
 M. Grosjean, of the ministry of agriculture. 
 
 <iA'l'HEKIN(l THK OTIOP. 
 
 In order to obtain the best possible results in the quality of fiber, 
 the i)lants should be gathered when the male stalks have shed their 
 riowers and tlie stems begin to be yellow, liegardiiig the sex of the 
 plant, the authors state in a footnote that "in many localities they give 
 the name oi' male hemp to those plants which bear the fruit, and that of 
 female hemp to those which have no fruit, a h-ss development, and in 
 which the \egetation is sooner arrested. This nomenclature is incor- 
 rect, as precisely the contrary (terms) should be emi)loyed." 
 
 The season of shedding the fiowers comes in the west of France 
 about the middle of July. There are two modes of gathering, depend- 
 ent upon the use to which the tii)er will be put. If for cordage, the 
 stalks are cut with a sharp instrument resembling a short scythe, and 
 laid upon the ground in sheaves, where they ai'e left to dry from one to 
 three days. The leaves are then stripi)ed aud the stalks removed to 
 the sheds to be assorted, ])laced in piles horizontally, the lower ends of 
 the stalks being pressed firmly against a wall, so that the inequalities 
 of their length may i>lainly ai>pear. Ui)on each pile there is placed 
 close to the wall a weight, to prevent deranging the stems while 
 drawing them out in assorting. This is done by haudfuls: first the 
 
 'A meter is iibout 3ij inches over a yard.

 longest stems, then the iiicdium, and then the short ones. They are 
 bound into sheaves, several of which are ])ut together, forming bundles, 
 each containing stalks of equal length. The tops of the sheaves are 
 then cut off, and only the portion ])reserved that will make good fiber. 
 When tlie hemp is grown for use in spinning, that is, for fabrics, the 
 stalks are not cut, but are pulled like fiax. The operator first removes 
 the leaves by passing his hand from toj) to bottom of the stalk, it being 
 important to return the leaves to the soil where they were grown. Six 
 to fifteen stalks are pulled at one operation, according to the ease with 
 which they can be drawn out of the ground, and the earth shaken off. 
 These handfuls are made into bundles about G inches in diameter; 
 after bundling, the roots and tops are cut off by means of an ax and 
 chopping block. The clipped stalks are then made up iuto larger 
 bundles a foot or more in diameter, and are sent to be retted at once, 
 as it is claimed that tln^ hemi> is not so white if it is dried before retting. 
 
 SAVING THE SEED. 
 
 In some localities the gathering of the hemp is so managed as to 
 secnre the greatest quantity of seed possible of good quality. To this 
 purpose the male stalks are first collected, which ripen six weeks earlier 
 than the female stalks, the latter being given plenty of time to mature 
 and not being gathered until their leaves and stems begin to turn yel- 
 low and the seeds to grow dark. They are tied in bunches, ami of 
 thes(^ there are made large bundles, whicli are ])laced upright, that the 
 seed may com])lete its opening. The seeds are extracted by beating 
 the stalks. This manner of operating produces less fiber, and these 
 female plants yield fiber of inferior (juality from those collected at the 
 time of maturing of the male plants; but the harvest of seed compen- 
 sates for the difference. If you take into account the expense occa- 
 sioned V)y the double harvesting and double retting, we find that there 
 is greater advantage in having but one harvest, without leference to 
 the seed. Dried in the air, the male hemp contains an average of 26 
 per cent of stripped hemp, and the female i)lants from 10 to li2 per 
 cent. The stripped hemp dried in the air does not yield more than (50 
 to 75 per (;ent of textile fiber, the renminder being foreign matter solu- 
 ble in leached alkali, so that 100 parts of green hemp do not produce 
 more than .") to 8 parts of textile fiber, 
 
 RETTING THE STALKS. 
 
 There are two systems of retting practice<l in western France, the 
 retting in the open field, where tlie stalks are allowed to lie about a. 
 month, and similar to the i)lan followed in Kentucky, in our own country, 
 and the water retting, whi(;h produces the best fiber. The water ret- 
 ting (rouissage) is accomplished both in i)ools and in running streams. 
 The river retting seems to accomplish tlie best results, although taking 
 a little longer time than the pool retting, the duration of immersion 
 
\ 
 
 12 
 
 varying from live to eigbt days. If the weatber is cold it retards tlie 
 operation two or three days longer than if warm. This accounts, too, 
 for the shorter time occupied when the immersion takes place in pools. 
 This work is usually done in the latter part of August. The bundles 
 of hemi) are floated in the water, secured if in a running stream, and 
 are covered with boards kept in place by stones or any weight that will 
 keep them under. From all that could be learned there is little pool ret- 
 ting- in the Sarthe district, although public opinion is generally against 
 river retting, on the score of its rendering the waters of the streams 
 foul and detrimental to health, as well as destroying all animal life 
 with which they should abound. There are said to be very stringent 
 police regulations against the use of streams for this j^urpose, and as 
 long ago as 1886, in a brochure published by M. Bary, a hemp spinner 
 of Le INIans, attention was called to the desirability of introducing an 
 improved method of retting, which would accomplish all the beneficial 
 results of retting in running water artificially, and therefore render 
 unnecessary the polluting of streams. From M. Janvier (of the hemp- 
 spinning establishment of Janvier, Pere et Fils et Cie, at Le Mans, 
 successors to M. Bary) it was learned that while many attemi^ts have 
 been nuide to bring about a better system, none have been successful, 
 and, police legulations to the contrary notwithstanding, the best hemj) 
 fiber produced in the Sarthe district is still retted in the running- 
 streams.' Where pool retting is followed the pools are specially con- 
 structed, dug out of the earth to the depth of a yard or more, walled 
 up or the sides made solid, and lined and fioored with cement usually, in 
 order that the water shall remain clean and the hemp retain its color. 
 The stalks are watched very closely after the third or fourth days, the 
 farmer breaking and examining a few at intervals to guard against 
 over retting, which weakens the fiber. 
 
 When sufficiently retted, whether the work is done in streams or 
 pools, the hemp bundles are removed from the water, but first agitated 
 to remove all waste matter that may be adhering to the stalks. They 
 are then drained, and the bundles, opened at the bottom, are set up in 
 conical sheaves to dry, this operation being accomplished in two or 
 three days. Considerable of the hemp grown in the Sarthe district 
 (the writer can not speak tor otlier sections) is further dried in brick- 
 kilns. One of these examined on a large hemp farm visited near Le 
 Mans, and at that time in operation, may be described as a circular 
 brick structure some 10 or V2 feet in height, resembling a smokehouse 
 in our country. It was built on a side hill, the door opening into the 
 chamber where the liemp was drying being on one level, the higher, while 
 the floor t© the fire pit, at the opi)osite side of the building, was on the 
 lower level. As no evidence of a fire was observed, it is inferred that 
 the fire is drawn when the right temperature has been reached, and 
 
 ^Such an improved process has recently been invented In Bels'inm, known as the 
 Loppens-l^pswarte system, and fnlly described in Eeport No, 10, Fiber Tnvestioa- 
 tions Series. Tt is applicable alike to hemp and to Hax rettinn.

 the lieiiii) iutiodnced upon the grated tioor to dry slowly by moderate 
 heat. The ^vriter witnessed the process of breaking hemp iu the Sarthe 
 district aud brought away samples of both stalks and cleaned fiber as 
 sent to market, as well as samples of scutched, softened, and dressed 
 liber prepared both for cordage manufacture and for weaving into 
 "linen." The stalks are of creamy whiteness, as brittle as j)ii)estem8, 
 and the tilasse, particularly next the wood, so bright in color that no 
 tinge of yellow is observable. A farm operator, upon being (questioned, 
 stated that he was able to break out 30 to 33 kilograms of fiber i^er 
 day (say 60 to 75 pounds). A brake similar iu principle to the old- 
 fashioned Kentucky hemp brake is used, though lighter and smaller in 
 the first jdace, produced with seven instead of five breaking slats 
 (arranged three opposite to four), both wood and metal being used in its 
 construction. Double this quantity of hemp is cleaned in a dny by the 
 negro operators in Kentucky, but it should be explained that the French 
 operator is nicer in his manipulation of the fiber, running through a 
 smaller ({uantity at one time, skillfully twisting the product into a very 
 loose rope or "streak" of fiber, these as produced being laid most care- 
 fully side by side so that when the larger bundle of fiber is made up each 
 has its place and can be detached from its fellows by the scutcher with 
 hardly the disarrangement of a filament. 
 
 SCUTCHING. 
 
 At a scutch mill, where, by the way, only hand scutching was prac- 
 ticed, the writer was shown some bales of softened fiber, and he after- 
 wards visited the establishmentof a hemp softener (Batteurde Chan vre), 
 near Le Mans, to observe the process. The mill was run by water power, 
 the fiber being manipulated on a circular platform a couple of feet in 
 height and perhaps 8 iu diameter, made of solid oak blocks placed on 
 end aud forming the surface. To a heavy spindle in the center was 
 attached a short conical cylinder of iron, weighing some 2,J:00 ijounds. 
 The "streaks," or ropes, of fiber as received from the farmer are made 
 up into bundles weighing perhaps 6i jwunds each, and these to the 
 amount of 130 pounds are arranged over the surface of the circular bed, 
 or platform. The heavy iron cone is then made to revolve or travel 
 around in a circle at a rate of speed equal to thirty-five times a minute, 
 the softening process re(iairing from half an hour to one hour and a 
 half, dependent upon the condition of the hemp under treatment. Only 
 the finest fiber is softened, the product going to the spinning mills for 
 the manufacture of coarse sheeting, shirting, canvas, and similar 
 fabrics, the peasantry of Brittany, for the most part, employing hemp 
 instead of fiax in the domestic economy. 
 
 Although these details relate to the manufacturing side of the indus- 
 try, rather than the agricultural, they are interesting as showing by 
 what careful means a fiber is produced in this country (France) that 
 will take the place of linen. While on this subject it may be added 
 
14 
 
 that the softeued liemp is not used in its whole length, but is broken 
 (pulled apart) into three pieces on a mechanical device for the purpose 
 found in all hemp mills (and even in our own country). The bottom 
 third is the best, and is kept separate for use in the finest numbers of 
 yarn. 
 
 THE CULTIVATION OF ITALIAN HEMP. 
 
 The best hemp which comes to this market is the Italian. Sc\ eral 
 varieties are cultivated in Italy, as already stated, though the princi- 
 pal variety is the Piedmontese or Bologna, the same that is grow n in 
 France. 
 
 Savorgnan states that the soil chosen foi- this culture in Italy is a 
 soft, deep, sedimentary fornmtion, and tliis is twice plowe<l in Novem- 
 ber, fifteen days intervening between the t\\ o plowings. The quantity 
 of seed sown varies according to the ^oil, climate, and variety of hemp, 
 but in Lombardy the average (luantity is 200 liters per hectare, or about 
 2i bushels per acre. The crojt is well fertilized, but not excessively, 
 and regard is had to economy of cost. In isddition to other fertilizers, 
 in Bologna, Professor Marconi names the following: First, manure and 
 olive husks (after the last pressing); second, manure and excrement 
 from hens (little used but very efhcacious); third, manure aiul chrys- 
 alides of worms, that is, silkworms; fourth, maiuire and olive husks 
 with one or more of the others. The guide for harvesting the crop is 
 the state of maturity of the tops, which become yellow, and the white 
 appearance at the foot of the stalks. First, the male plants are har- 
 vested, and twenty or twenty-four days later the female plants. These 
 two operations are never retaided nor preci})itated. After cutting, the 
 stalks are removed to a shady place and the tops inclined over a sort 
 of trestle to dry. Ten or twelve handfuls of stalks form a bundle of 
 equal-length stems for the operation of retting. 
 
 DRYING AND (JLEANINtl. 
 
 The stalks are retted in water and either dried in the open air, in 
 furnaces, or in trenches, the last practice being rarely used. Drying in 
 the open air has advantages over any other method : First, it is less 
 exj^ensive; second, a superior bleaching of the fiber is secured. In the 
 ovens the operation is hastened, and in many ways this is a very desir- 
 able systenj. In a perfectly dry atmosphere three to six days suffice for 
 drying thoroughly. The stalks are again put into bundles and placed 
 in dry locations, safe from .rodents. The drying by artilicial heat is 
 done in common bread ovens, but the temperature should be very mod- 
 erate; usually the hemp is introduced one hour or one hour and a half 
 after the removal of the bread from the oven. The liemp stalks are 
 decorticated in various ways by hand processes of beating or by 
 machinery. The French brake, Avhich is somewhat similar to tbe Ken 
 tucky brake, is little used, though ;i machine quite as primitive is 
 
15 
 
 largely employed. In tliis device the stalks are ttrst crushed, theu 
 cleaned by beatiug. The heinp is not ready for market when it comes 
 from this machine, but is further cleaned, and the bits of wood, etc., 
 which adhere to the fibers are carefully removed. 
 
 It may be stated that in favorable soils Italian hemp averages a yield 
 of 1,700 to -5,200 pounds of dry stalks per acre, which produce from 450 
 to 530 pounds of tiber. "In general, 100 kilos of raw hemp furnish 25 
 kilos of raw filasse, and 100 kilos of ordinary tilasse (fiber) give 05 kilos 
 combed tilasse and .'>2 kilos of towj 100 kilos of seed furnish 27 kilos of 
 oil.'' A kilo is 2.2 pounds. 
 
 In the foregoing statemeuts it has only been attempted to outline the 
 general practice of Italy, leaving the details to be presented in a special 
 rei)ort on the hemp culture of Bologna and Ferrara, i)repared by 
 United States Consular Agent Carlos Gardini, of Bologna, Italy, and 
 transmitted through the Department of State. As reference has already 
 been made to the su^jeriority of this hemp, an account of the methods 
 by which it is produced, at a time when American growers are endeav- 
 oring to improve the native product by more careful culture and pre^jar- 
 ation, is a valuable contribution to the literature of the subject, and 
 the report is therefore commended to all who are interested in the 
 growth in America of this important textile. 
 
 REPORT OF UNITED STATES CONSULAR AGENT CARLO GARDINI. 
 
 [Sulimitted to State Departuioiit from Bologua under dnW July 24, 1897.] 
 
 One of the most important agricultural industries of the Italian 
 
 provinces of Bologna and Ferrara is the cultivation of h(imp. Bologna 
 
 hemp is generally manufactured into yarns for canvas and twines; the 
 
 Ferrara hemp is principally Avorked up by rope spinners. The former 
 
 has a softer and brighter fiber than the latter but not so strong; they 
 
 are both, however, held in liigh esteem in textile centers abroad, chieHy 
 
 iu Germany, Austria, France, England, Spain, and in the United 
 
 States. ^ 
 The cultivation of hemp has developed greatly in these provinces 
 
 owing to the favorable conditions of the climate and soil. This plant 
 sprouts at 8° C. (4Go F.) and thrives well at 23° C. (73° F.). From its 
 sowing to cutting for fiber the total amount of heat it reipiires is 2,100° 
 C. (3,128° F.), and from sowing to cutting for seed 2,700° C. (4,892° 
 F.). Hemp may be cultivate*! ])etween the equator and G0° latitude, 
 and when it is rationally treated no other plant gives more i)rofitj at 
 the same time it leaves the soil in such a good condition tha^ the fol- 
 lowing crop (wheat) is almost marvelous. 
 
 'The exportation viiluc of J5ologua and Feirtirii hemp certitied by this consular 
 agency from July 1, 1895, to June 30, 1896, iiuiounted to $216,690.94, and from .Inly 1, 
 1896, to. June 30, 1897, to $219,475.r)9. But many other invoices of considerable 
 amount of hemp of the same provinces were certified at Leghorn, Venice, Liverpool, 
 and Ilajjibnrg by the respective Luited .States consulates.

 ORIGIN AND DESCRIPTION OF THE HEMP PLANT. 
 
 The hemp plant, Canimhis sativa, is of Persian origin and grows wild 
 in northern India and Siberia. The plants are male and female, the 
 latter producing the seed. They have a long, white, fibril, tapered 
 root; the stems are straight and ramified, if grown isolated, and 
 covered with a hairy or velveted coat; height from 3 to 15 feet. Their 
 branches grow opposite each other and bear five or seveu small lanceo- 
 lated leaves toothed at the margin. The female fiower is sexual, almost 
 invisible, a single cup-shaped shell longitudinally oi)eu on one side, 
 with one ovary surmounted by two small woolly coated plus or points. 
 The seed is in a horny bivalvular capsule or pod containing one seed. 
 The fiowers are grouped in bunches, and the seed is of a dark green 
 color and black striped when ripe and pale green when just formed. 
 
 The male plant bears cup shaped flowers also, the branches of which 
 are divided into five smaller leaves and five shorter stems with oblong 
 tetragon anthers, disposed in small bunches scattered here and there on 
 the stetns of the top leaves, ordinarily in a green cluster, and when 
 ripe they turn yellow. The male stems tend less to branch. 
 
 The diversity of quality in hemp for yarns and canvas and that for 
 rope does not arise from the difi'erence in the plants, but from the results 
 of vegetation, culture, steeping, and general manipulation. The same 
 hemp bed will produce from the center file a good, long, resisting fiber, 
 while from the sides of the same bed a short, hard fiber may be had, 
 only fit for the rojie spinner.

 Hemp growing in a wild state will not yield the fiber and kind of 
 dressed line the Bologna and Ferrara plants do. The art of cultnie 
 compels it to grow in thin, slender, erect stems, and crowded together, 
 in order to obliterate the i)ossibility of their branching. Isolated or 
 wild plants on i)oor, badly tilled soil, do not grow to any height. In 
 a deep, rich, and well-prepared loam, though they might reach the 
 height of -0 feet, the stems would be rough, thick, and branchy, pro- 
 ducing coarse, barky Hlaments only fit for the manufacture of rope. 
 Good tilling and manuring is not sufficient, though. The stems, being 
 crowded togitiier, reciprocally shade each other, and they grow up thin 
 and slender, yielding a soft, silky, bright, strong fiber. 
 
 The seed sparingly sown produces thick stems, especially at the root 
 end of the plant, and will yield 15 per cent less fiber than thickly sown 
 seed ; consequently it produces broad, ribbon root ends, which are graded 
 "'rejected." This plant vegetates with success in temperate climates, 
 and if it succeeds in moderately cold regions it is on account of there 
 beiug about one hundred and fifty days of suflicient heat for its hurried 
 vegetation. 
 
 KIND OF SOIL REQUIRED FOR BEST RESULTS. 
 
 A rich, siliceous-calcareons-argillousloam is generally regarded as the 
 best soil for its cultivation. The seed bed should possess this natural 
 friable composition to the depth of about 15 to 21 inches, which is as 
 far down as the work of digging goes after the plow has cut the fur- 
 rows. Generally it is sown after a crop of wheat; sometimes it is put 
 on to artificial grass plots, and sometimes, but seldom, it is sown year 
 after year on the same land. 
 
 PREPARATION OF THE SOIL. 
 
 There must be a thorough jireparation of the soil to facilitate the 
 penetration of the long, tapered roots in order to preser\e a proper pro- 
 portion of moisture during the hot weather, and also to clean the soil of 
 weeds. After grain reaping, toward the end of June or beginning of 
 July, the plot chosen for the seed bed is plowed in such a manner as to 
 pile up the soil furrow to furrow, so that the soil of each furrow will 
 cover a portion of land, to be plowed in turn after an interval of a fort- 
 night; meantime, the bottom of each furrow is dugout and the soil 
 placed above that already turned by the plow. In about a fortnight 
 plow through the ridges over which the soil of the former two furrows 
 M-as turned, and dig below the plow blade as before, turning the soil 
 over right and left out of the newly made furrow, or trench. 
 
 In August, after a good manuring, plowing is resorted to once more 
 to cover in. On small farms deep digging is customary. In Novem- 
 ber or December the bed or plat is leveled by means of a heavy ladder- 
 
19

 bed from end to end, after which the phit is more perfectly leveled by 
 
 Flo. 1 Implement used lor leveling tlie hind. 
 
 the use of hoe aud spade, bearing in luind to [)reservc a uuiforin 
 convexity of bed. 
 
 SEED — TIME AND QUANTITY To SOW. 
 
 Sowing commences in February or the first fortnight of March, and 
 from (io to 75 liters of seed is sown per hectare (nearly 2i acres). This 
 is covered iu by the hoe, and the surface of bed nicely leveled by 
 raking over. 
 
 A siliceous-argillous soil is well adapted for this cultivation when 
 situated iu a low, cool country. In elevated localities, if showers are 
 lacking in May, the vegetation is sorely checked, consideriug the plants 
 flower too soon. The (cultivation, therefore, is not limited to any con- 
 ditions of temperature, aud extends throughout uumy parts of Europe. 
 It depends mostly upon the conditions of the soil ; when this is not deep, 
 friable, cool, aud at the same time souud, the plant will not thrive. 
 
 AMOVTNT OF PRODUCT. 
 
 The yield depeuds greatly on the regular and constant proi)ortion of 
 moisture contained iu the soil. When the plant has grown to the 
 height of 1 foot, even an extreme drenching could not harm it, unless 
 it lasted some days. Watering is not considered essential, although it 
 is advantageous, no doubt, in long, dry, obstinate seasons. From 20 to 
 I'd hundredweight could be produced during a dry season by watering, 
 where only from 10 to 12 hundredweight could be had, owing to the 
 iuterriii»tion of the plant's growth by drought. 
 
 ALTERNATE CROPS. 
 
 Hemp alternates most commonly with wheat, the former giving the 
 best results iu rotation, inasmuch as it leaves the land free of weeds, 
 very rich, and iu such a condition that wheat may be sown to the best 
 advantage without much dressing. On the Bologna plains the farms 
 are disposed on a very economical system — iu long, rectangular plats, 
 with a row of elms along each side. The hemp is sown at a distance 
 of about 12 feet ou each side from the row of trees. 
 
 The following rotation of crops is recommended : Luceru for fodder, 
 hemp, aud wheat.

 APPLICATION OF MANURE. 
 
 Although hemp, in rotation with wheat, leaves a powerful fertilizing 
 matter in the helds, maize should never foUoAv a wheat crop to be fol- 
 lowed in turn by hemp, unless the land is richly manured. As before 
 stated, the hemp plant is most exhaustive to the soil in cultiA^ation, but 
 it fjives back by its residues a large proportion of iertilizing material, 
 especially when it is realized that a considerable quantity is depos- 
 ited in the steeping pits, which must be cleaned out and the mud 
 spread over the fields, supplying an excellent manure. The quantity 
 of manure required per hectare is about 30 tons; less is required when 
 the hemp fields have once been well prepared. In the Bologna district 
 manuring is done in a very systematic and lational manner. The farm 
 manure is well mixed under the lowest stratum of soil; then the otluu- 
 manures are worked into the medium stratum, and, last of all, before 
 sowing, in order to increase its richness, hen manure or oil cake refuse 
 is spread over the surface. Experience has shown that manuring by 
 penning sheep on the land at night gives most excellent results. 
 
 Several kinds of manure may be used, such as soot, Avhich is ad van 
 tageous in destroying the parasitical weed Fhelipea raniosa, a fatal 
 pest to the hemp. Oil-cake refuse, or any oily residual matter, is 
 excellent for producing good line. Hoofs or feathers are considered 
 the best — hoofs for soil where silex abounds, feathers for a hard, sub- 
 stantial loam. ISTight soil is as efficacious as the droppings of fowls. 
 Guano is advantageous when scattered over the surface of the field 
 
21 
 
 and worked in with the hoe just before sowing-. Hair (animal), cotton 
 and woolen rags, besides the mad taken from the steeping pools and 
 left in a heap for some months, are all excellent surface manures. Beans, 
 too, are sowed and plowed into the soil at maturity. 
 
 Manures should be applied as follows: 
 
 (1) To the lower stratum of soil. (2) Over the furrows, which are 
 then covered. (3) Scatter the last manuring over the hemp field and 
 work in with the hoe shortly before sowing.

 Five tons of bean stalks (calculated as dry) contain about 3 hundred 
 weight of nitrogen, equal to IG tons of fiirm manures. 
 
 The fields manured as to I, II, III will do well for wheat crops in 
 succession, being rather strong; Vlil is weaker. 
 
 Fertilizing substances, containing nitrogen or phosphates alone, check 
 the vegetation of hemp; therefore the best manure is considered that 
 produced on the farm. 
 
 The fields, oidinarily 90 yards long by 40 broad, should be nicely 
 raked and dressed, so that they will be slightly convex. 
 
 Cart, scatter, and bury the fertilizer for the first manuring in August, 
 and sow the beans at once if considered necessary. In November plow 
 and dig up under the furrows, covering- in the bean stalks, if sown. 
 Weather permitting, hoe, weed, and cover over the superficial manure 
 in February, remembering to dress the soil when almost dry, thoroughly 
 working in all the bean stalks. 
 
 SOWING THE SEED. 
 
 Having prepared the soil during winter, it is an easy matter to dress 
 for sowing. The seed should be a gray-green, black-striped, brilliant 
 color, and so heavy as not to float on water. Black or whitish colored 
 seed must be discarded, not having been ripe when gathered. Sixty- 
 five to seventy-five liters per hectare (or approximately li to 2 bushels

 Mark off the fields into beds about 8 feet wide. The seed is sown 
 broadcast early in March, and this operation should be intrusted to 
 
22 
 
 tliose who have a thorough knowledge of the crop and an interest in 
 tlie result of the liarvest. To have portions of laud sparsely covered 
 and others too thickly covered will cause much irregularity and reduce 
 the commercial value of the liber produced. 
 
 HOW TO TEST THE (,)TTAEITY OF SEED. 
 
 To ascertain if the seed is in good condition and containing all its 
 germinating properties, bieak open a few of them. If they have a 
 musty, oily taste, the seed is old. Seed three years old will not sprout. 
 When the farmers have any doubts about the quality, they count 100 
 seeds and sow tliem in a flowerpot, keeping the soil damp and i>lacing- 
 the pot in the warmest nook in the stable. In eight or ten days the 
 seed will sprout; 90 per cent of sprouts indicates a firstclass quality of 
 seed.; 70 to SO per cejit, fairly good. I>y this means it is possible to 
 estimate very closely how much to sow to obtain an even growth over 
 the field. Some sow by machinery with good results, the practice also 
 saving seed.' 
 
 WEEDING THE CUOV. 
 
 Favorable weather and a temperature of 10° C, with sufficient moist- 
 ure, will enable the young- 
 plants to appear in five to 
 eight days, after which it 
 is advisable to weed. In 
 a wet spring weeding is 
 resorted to three or four 
 times. When the plants 
 are about 2 inches high, 
 
 Fto. 2.— Hop used for wccilina;. , . , , •, • 
 
 bearing two leaves, it is 
 necessary to weed with the so-called weeding hoe (flg. 2). Repeat this 
 operation when from 5 to 8 inches high. 
 
 PRODTTCTTON PER HECTARE. 
 
 If too thickly sown, when about 4 feet high the plant stops growing 
 and begins to lose its dark-green color and Howers. When rationally 
 treated this plant will stop growing only for want of moisture in 
 very dry seasons, yielding from 20 to 20 hundredweight of fiber per 
 hectare, tow and rejected included. The green stalks, when ready for 
 cutting, weigh from 19 to 30 tons. The loss in drying and casting of 
 leaves is from 30 to 35 per cent. Approximately, 19 tons will be the

 NEED OF R[CH NOURISHMENT. 
 
 Comfort and abundant nourishment in animal life hasten puberty — 
 the contrary to what takes place when in a wild state, and when growth 
 is stunted. Vegetable life, on the contrary, presents in this respect a 
 decided contrast. Substantial and abundant nutriment tends to retard 
 development of the generative properties, and the plant blooms later, 
 and later still produces seed; therefore when the hemp plant in its 
 infancy finds itself in unfavorable and stinted conditions, it flowers and 
 seeds very soon. This will occur also when too thickly sown, which 
 defect deprives it of sufficient nourishment and space to spread its roots. 
 
 EFFECT OF HOT AND WET WEATHER. 
 
 When the stalks show signs of rusting after alternate days of wet 
 and hot weather, it is advisable to hurry the cutting. Drops of water 
 on the plants evaporate by the sun's action, leaving black or red spots, 
 which damage the fiber. After it is V2 to 14 inches high little attention 
 is needed until it reaches maturity. At this height tlie plants cover 
 the soil, protect it from the sun, and thus preserve it cool, besides suifo- 
 cating the ever obstinate reproduction of weeds. 
 
 A PARASITE. 
 
 Phelipea rmnosa (a vegetable parasite of the honeysuckle species) is 
 a fatal enemy to hemp. It germinates on its roots, depriving them of 
 nourishment and causing the plants to flower very soon. This para- 
 site grows pods full of very small seed, which preserve their germinat- 
 ing i^roperties for years. To extirpate this destructive parasite it is 
 indispensable to change the rotation of crops for a few years, or to cut 
 the hemp as far down :is possible before the parasite flowers. Very 
 approiniately, the Germans call this terrible weed Hanfmurder (the 
 hemp murderer). 
 
 WHEN AND HOW TO CUT THE CROP. 
 
 Cutting begins toward the end of July or early in August, when the 
 male i^lants throw oft' a dusty substance, the best time being during 
 the course of change from dark green to a. light-brown color and before 
 
24

 the stalks become yellow. This, however, must be determined accord- 
 ing to circumstances and practical experience. The farmer cuts tbe 
 stalks with a kind of scythe (flg. 3), by taking an armful under his left 
 
 arm and between it and 
 his body, cutting with the 
 right just above the sur- 
 face of the bed, and then 
 laying them across each 
 other diagonally until a 
 sheaf is complete. A ])or- 
 tion of the l)est of the 
 female i)lants is lelt grow- 
 ing to produce seed. 
 When the stalks have 
 lain a day or two in the 
 sun they are turned over, 
 and when dry the sheaves 
 are taken up and beaten 
 on the earth to strip them 
 of their leaves. The stalks are then set up on their root ends, so as to 
 make conical shaped stacks about 9 feet in diameter at the base, wliich 
 are left standing a few days to further dry and season. 
 
 DRYING AND .SORTING THE STALKS. 
 
 The steeping or retting j)rocess is quicker when the stalks are not 
 altogether dry, but, by thoroughly drying, many inconveuiences are 
 avoided. 
 
 Before steeping all the several lengths of stalks are bunched 
 together by sorting. In wet weather never allow the sheaves to lie on 
 the field, otherwise a l>lack, unsound fiber will be produced. 
 
 The stalks, being perfectly dry, are carried to a shaded locality on the 
 farm and laid on an inclined bench with all the root ends together. 
 They are then evened up with a broad-faced mallet, so as to make an 
 even vertical surface. When the bench is sufficiently full a very heavy 
 beam of wood is placed across to maintain pressure; then the opera- 
 tion of sorting commences. The farthest i)rojecting stems are drawn 
 out by taking hold of the tops and pulling horizontally. A large 
 handful of these, being then held perpendicular, root end down, rest- 
 ing on the ground, are tied up about 1 foot from the root end and 2 feet 
 from the tops with a thin green hemp stalk, a bundle of which is near 
 at hand for that purpose. This operation is carried on until the bench 
 is dra,wn. Thus the long, thick, medium, and short fiber becomes 
 sorted, besides separating the rejected. For this operation all leaves, 
 branches, and any weeds must be stripped off". 
 
 The bundles of stalks are made up of twelve to fourteen sheaves, one 
 over the other, the roots and tops placed end to end, the latter project- 
 ing, so that when tied up with green hemi) stalks, as before, they form 
 
25 
 
 a somewhat cylindrical bundle. After the bundles are made up the 
 projecting- tops are cut oiT square to the root ends. If the bundles 
 were not made up in this manner they wonld be difficult to cart and 
 would give less uniformity during the steeping i)rocess. Stalks so 
 bundled can be stored year after year in dry warehouses without fear 
 of damage. 
 
 Twelve sheaves, that is, one bundle, of good hemj) will yield 4i pounds 
 of liber, though this depends on length and quality. 
 
 CATMNG FOR SEED. 
 
 About a month after cutting for fiber the female plants that were left 
 to ripen will be ready. They are cut carefully, so as not to lose the seed, 
 dried in the sun, well seasoned, the seed sifted, sacked, and kept dry. 
 
 The female stalks, owing to the advanced season, are very often dried, 
 to be kept until the following year, (lood seed is plump and glossy 
 and feels damj); it is white in color, with small black markings. When 
 the inside is black it has been damaged by fermentation; if dusty, it is 
 old and too dry, and therefore not serviceable. A good quality of seed 
 when rubbed between the hands becomes glossy; if dropped on red-hot 
 iron it cracks and bursts. 
 
 llETTINCi THE STALKS. 
 
 The structure of the bark of the stems shows that retting or steep- 
 ing is absolutely necessary. Each stalk is composed of a woody tubu- 
 lar structure, around which clings a network of longitudinal filaments, 
 bound together by a substance insoluble in water. By steeping a sort 
 of decomposition is induced, through which the intercelluhir matter is 
 rendered soluble. Thenard and Orfila found by exi3eriraents that the 
 bark is composed of A'egetable fiber, resin, green coloring matter, and 
 glutinous sap, by which substances it sticks to the stalk. In the opera- 
 tion of retting the last two become putrified. 
 
 Fermentation damages the fiber, but the fiber resists the action longer 
 than the binding ligaments, consequently the retting process consists 
 in allowing the hemp to decomi)ose these substances without injury to 
 the filament. The fiber, according to Girardin, is under the epidermis 
 and bound to the woody cylindrical stalk by means of a resinous gum, 
 so that it can not be extracted unless separated by fermentation, which 
 action rots the binding ligaments. 
 
 Hemp must be steeped in stagnant water, about 10° C, which has been 
 standing in the steeping pools at least a month to purify and become 
 aerated, so that it will not injure the fiber. The steeping or retting 
 process is more or less rapid, according to the temperature of the water 
 as affected by the sun, according to the nature of the water, the kind 
 of weather, and the quality of the hemp itself. 
 
 In hot weather, when possible, after the first steeping it is best to 
 draw or run oft" about a foot of water and replenish with fresh. 
 
26 
 
 Tliere are two forms of rettinji' or steepiii^y' pits, one fitted with stakes 
 (tig. 4), the other with rows of stones (tig. 5). In each of these pits 
 two rettiugs are effected iu succession by sinking the bundles of stalks 
 four layers deep in the stake steeping pools. The first steeping takes 
 about eight days, the second a little longer: but, during the second 
 steeping, if the water gives signs of "ebullition" the hemp must be 
 taken out immediately.

 If the fiber can be removed from the surface of the wood}' portion of 
 the stalk by passing it between the finger and tliumb it may be con- 
 cluded that the operation is complete; or if, by bending a stalk, the 
 woody part starts from the fiber, it is clearly in a condition to be taken 
 out of the water. 
 
 Large steeping pits are preferable. The depth should not exceed 
 5 feet, to allow the water to be at an approximate uniform temperature 
 from surface to bottom. The height of the water above the sunken 
 hem]) should never be under 12 inches in any retting pool. 
 
27 
 
 STAKK ItKTTIW! POOL. 
 
 Fig. 4 is :i stake letting pool, sliowiug hemp bundles under submer- 
 sion. The ground arouud these should slope inward, the sides inclined 
 to about 4;") degrees, and should be lined with oak planks li inches 
 thick. 
 
 At one side of the stake steeping pool make a platform, so that the 
 laborer wheu steeping, taking out, and washing will uot have the water 
 much above his waist. The bottom should be made level, slightly 
 inclined to the drain. There are two rows of square stakes, standing 
 up to water level, along the length of the pit, to which horizontal 
 wooden spars are nailed, top and bottom. Under the top horizontal 
 spars, running from end to end, long wood levers are inserted to sink 
 the bundles. 
 
 STONE RETTING POOL. 
 
 It is best to build the stone steeping i)ools with brick walls. The 
 bundles in this kind of steeping pit are sunk by tying them together 
 and loading with stones taken from the I'ows. These pools should not 
 be more than 3 feet deep; this system is handy when there is little or 
 no means of drainage. When the steeping is finished, the pools are 
 left to dry up or are pumped out and the stones placed again in rows 
 distant from eacli other the length of the bundles. In a stone steeping 
 pit one man arranges the bundles in layers, holding them together by 
 means of a rope, while a second man holds the rope <it the other end 
 and walks backward to the opposite side of tlie pit as the bundles are 
 put in, and until the range of bundles is complete. This range is then 
 tied up and sunk by heaping on stones taken from the b(^ttom of the 
 pool. 
 
 DHVINc; THE STAI.KS. 
 
 After five or six days' steeping, take a sheaf from the pit, wash it, 
 open it out, and stand it on the grass, roots down, in conical-tent shape, 
 to dry in the sun. If, when dry, the color and strength are satisfac- 
 tory, all the other bundles should be taken out the following morning. 
 A night longer in the pit does no harm, owing to the low atmospheric 
 temperature. The range of bundles is untied, the bundles opened, and 
 each sheaf carefully washed, thrown out, and set up, root end down, in 
 large x»yramidal sheaves, to drip for about twelve hours, in which con- 
 dition the tiber gains in color and loses a great deal in weight, in case 
 it has to be carted anywhere for drying. 
 
 The sheaves are then opened out, in the form of conical tents, to dry. 
 
 Should it rain during the drying period, the fiber loses part of its 
 gloss and contracts a roughness, which is perceived by the touch. 
 
 Always open out to dry on closely cropped gTass land, to avoid splash- 
 ing with mud. When dry, tie the hemp again in bunches and stove, 
 remembering that if not perfectly dry the fiber will rot. 
 
28 
 
 SCUTCHINa AND CRUSHING. 
 
 The next operation is scutching and crushing". To reduce the fiber 
 to a marketable condition the most simple, strong;, and economical 
 machinery is required. The compound scutcher and crusher is most 
 commonly employed. The hemp is scutched by gradually pushing- 
 sheaves under the scutching blades, roots foremost, and then through 
 the crusher, which has a pair of tinted cast-iron rollers, one above the 
 other, working- closely together. The sheaves are fed in without the 
 application of any traveling- apron or feed arrangement. The top 
 roller is heavily weighted, so between it and the bottom one the crush- 
 ing is accomplished. The first operation roughly breaks the sticks, 
 thus disintegrating them from the fiber. 
 
 When scutched all its length, the man feeding the scutcher hands 
 the " streak " to a man on his right, who breaks up the thin sticks at the 
 tops, shakes the fibers well in order to allow the broken fragments to 
 drop, gives the streak a twist about the middle and lays it in a heap, 
 while a man on the scutciher's left hands him another sheaf to run 
 through. Two gangs are generally emi)loyed, one scutching, the other 
 crushing, shaking, and tossing the streaks coming from the crusher, to 
 get out all the woody matter possible. 
 
 After scutching and crushing- the hand beater is very often employed 
 to improve the quality of fiber by further separating- its tissues; it 
 gets spread more equally, and becomes softer and more brilliant. 
 
 FINISHING TOUCHES. 
 
 Scutching, crushing, and beating- over, the most intelligent men on 
 the farm are chosen to give to the fiber the finishing touch. 
 
 The streaks are taken one by one, the black fibers drawn out, along 
 with any thick root ends, and all nicely matched by sorting and putting- 
 together all hemp of the same length. On a clear night these streaks are 
 taken from the store and spread on the grass to absorb a little dew, which 
 is very beneficial, though care must be taken never to drench it, other- 
 wise the fiber will rot. Each streak is then folded in two and twisted 
 at the middle to avoid mixing- and becoming ruffled. They are then 
 put carefully on a low platform of planks, layer upon layer, so as to 
 make u]) the so-called •' i^arcel." 
 
 If hemp has to be stored any length of time, it is advisable to bale 
 it, avoiding thus any serious damage in case of fire. The bales weigh 
 from 300 to 400 pounds. 
 
 Fig. 6 represents a Bologna farm of 11 hectares, 2 of which we must 
 suppose are taken up by buildings, farmyard, steeping pit, roads, and 
 walks. Each field is 125 meters long by 40 wide (one-half hectare, or 
 about an acre and a fourth). SS and SS are the roads, and Z the 
 steeping pit.

 C, B, aud A are the three ranges of tielcls, Hrst, second and tliird. 
 Suppose the range C is on hemp cultivation, range 1> on lucern grass, 
 and range A on wheat. The first field or bed of range C at the corner 
 Z will be No. 1, the next No. 2, and the last No. G, all on hemp cultiva- 
 tion. The first bed of range B will be No. 7, the last No. 12, all grow- 
 ing lucern, including the two beds Nos. 9 and 10, portions of which 
 are built upon. No. 13 will be the first bed of the A range, the last No. 
 18, all growing wheat. 
 
 Where there are rows of trees, neither hemp nor lucern is sown within 
 12 feet of them, including the drains. Potatoes aud turnips are grown 
 under the elms. 
 
 If this plant suffers a hailstorm in its infancy, no matter how light, 
 it is advisable to hoe ui) and sow again. If visited by a disaster of

 this kind in June or July, cut and steep immediately. By allowing it 
 to grow, more will bti lost than gained, both in ([uality and quantity. 
 The surface of hemp beds becomes crusty if heavy rains follow sowing, 
 consequently the seed sprouts with difticulty. After sprouting, the 
 same heavy showers will damage it most fearfully by splashing; the 
 mud will stick to the leaves and stalks and choke them. Heavy winds 
 beat the stems together and bruise the epidermis, leaving a very visible 
 mark on the fiber. Sometimes a crop is partly destroyed. If the plant 
 does not get enough rain early in June, it will not yield much fiber. 
 Hemp has eneruies, also, among the insects ; some devour the leaves, the 
 rhordon cannabis destroys its seed, and, above all, the I>oti/s .Hilaeeaiis, 
 which eats through the stalks, nourishing itself upon the marrow 
 therein.
