In usum Delphini: The Biltmore lectures on Forest Finance appear in print since it is nec- essary to place in the hands of the Biltmore students some basal findings con- cerning the financial side of forestry, which findings it is not easy for them to obtain elsewhere. In America, forest finance is and will be the most important branch of forestry; the very difficulty of the financial problems involved in American forestry is enticing; and I am interested, personally, more deeply in the scien- tific and practical development of forest finance than in that of any other branch of American forestry. Special students desirous to attend the Biltmore lectures on forest finance, and otherwise excluded from the Biltmore School, will be welcomed at Bilt- more hereafter. This arrangement is made for the reason that the lecturer is anxious to study forest finance through and with the students — the regulars as well as the specials. Co-operation between teacher and pupil is essential to the development of American forest finance. The interest tables attached to this book are obtained, by extraction and addition, from those published by the Mutual Life Insurance Company of New York. C. A. SCEENCE.

Treated as a branch of science in European literature, it consists of two parts: First Part: Forest Valuation which ascertains the values of forest in- vestments and the values of their components. Second Part: Forest Statics which compares the investments with the returns obtained. Forestry, from the standpoint of a commonweal (federation, state, county, town, city) deals, to a large extent, in abstract or ideal values, — values which are not expressible easily in dollars and cents. It neglects, usually, financial considerations entirely or partially. With the private owner of forests, the financial outcome of his invest- ments is the first and last consideration. The priva!e owner cannot be ex- pected to supply this country with forest products u:iless forestry is as remun- erative an investment as agriculture is found to be, or as manufacture is sup- posed to be, — industries which supply this country v/ith food products and with manufactured products. The mathematical principles involved in Forest Finance arc identical with those confronting the bankers, the insurance companies, — in fact, corironting all business men and all business enterprises that lock ahead into the future. Forest statistics, deficient unfortunately in the United Stares (as in any ether country of rapid development), are important as a basis for financial calculations. Forestal forecasfs in the countries famous for conservative forestry are made easily and with a high degree of certainty. In Canada, in Russia, and generally in the United States, such is not the case. II. History. Forest Finance is one of the most modern branches of forestry. Abroad, i\ was unknown, or unheeded by the practitioners, previous to Max Pressler (about 1860). Pressler's theories were developed and enlarged upon by Gus- tav Heyer. Dr. Wm. Schlich's, and Prof. Charles Vv^immenauer's writings are entirely in line with Heyer's teachings. Financial considerations were despised generally by European foresters until recently. The government cf Saxony was first to adopt financial suc- cess as the goal of its forest policy. sf-^ ^ FOREST FINANCE. - ^. — III. Literafure. The only book on forest finance written ki English is SGiilich''s Vof. IIT, Part II. The interest tables of the various insurance companies may be used to solve forestal equations, in preference to tables of logarithms, PARAGRAFH IL— MATHEMATICAL PRINCIPLES OF FINANCE. The ratio existing between principal invested (V) and atnount obtained" (N), or the ratio between "pre- value" and "aft-value" of an investment is expressed by the following equations [in which (p) represents the rate of in- terest and (n) the number of years covered by the investments}: — N = VXL Op°' (A) N V - ^ = y-^- (B) 1. Op'' <^ .. ^ ^ ^ "// ' N ^ I. Op« = (C) V By payments (a) regularly occurring at given intervals of time a "geom- etrical progression" is formed after the pattern a + ar + ar^ + ar' + ar* + ar(n - 1) The summary of this geometrical progression is r"— 1 a — (Dl r — 1 If the last term of the progression is expressed as "I" (with the view to the elimination of "n"), the summary is / r I — a 4. r — 1 might be designated as "the term beyond the last", or as the terns "before whicTi the progression stops". Similarly, the sum total of periodical payments (R) due at intervals of (m) years, for the first time due after (a) yep.rs and altogether (n) times is, considered as a pre-value, 1. Op™°— 1 1. Op"'a R X (E) 1. 0pm — 1 1. Opmn On the other hand, for the aft-value of such periodical payments (R), the sum total is 1. Op«« — 1 R XI. Opni-a (F) 1. Op°J — 1 In the case of an annuity, (m) and (a) are equal to 1. Consequently, the summary of such annuities considered as a pre-value is FOREST FINANCE 7 1. Op" — 1 R (G) 1. Op°XO. Op The aft-value of such annuities is 1. Opn — 1 (H) 0. Op The aft-value of sixigle payments, annuities and periodical payments at the end of an indefinite period is itself indefinite ( C^ ). The pre-value of a single payment due after an indefinite period of years is equal to zero. The pre-value (V) of annuities or periodical payments running for an indefinite number of years is, however, something very definite, namely, dis- counted backwards to the present day, in the case of an annuity: R V = (I) 0. Op or R 100 V It appears at a glance that this pre-value (V) derived from never-failing annuities — is merely the capital from which a perpetual revenue of p% is expected. Unknowingly, the investor usually figures at indefinitely long per- iods of never failing returns when capitalizing such returns at a given rate of interest. It is only too well known, however, that all investments, except- ing pure real estate investments, have a merely temporary lease of life. As an illustration, we might mind the fact, that the majority of all insurance policies are surrendered, — the insured being unable to pay his dues when he meets with financial reverses : Business investments, in the majority of cases, seem to end unluckily for the investor. The pre-value (V) of periodical payments (R) hereafter due at the end of every 'mth" year until infinity is R V = . (J) 1. Op™ — 1 The influence on present values exercised by payments (receipts or ex- penses), expected after 100 and more years, is very small. For the financial prospects of an enterprise, the current expenses and receipts of the first (n) years are (1. op° — 1) times as influential as the current expenses and receipts of any and all years following after the nth year. The above factor of influence, viz. (1. op° — 1), equals 10 within 50 years, in case of 5% investments ; 63 years, in case of 4% investments; 83 years, in case of 3% investments. 8 FOREST FINANCE "PROVIDED THAT THE RATE OF INTEREST IS HIGH, THE HAP- PENINGS OF A MORE DISTANT FUTURE ARE IMMATERIAL TO THE INVESTOR."

THE EQUATION MERELY ILLUSTRATES A LOGICAL MANNER OF FINANCIAL THINK- ING, WHICH IS GENERALLY ADOPTED BY THE INSURANCE COMPAN- IES, BANKERS, AND FAR-SIGHTED BUSINESS MEN. PARAGRAPH III.— INCREASING OR DECREASING PRICES. Stumpage prices are rising in America, — possibly at the rate at which the population increases, possibly faster, — promising to reach the present European level within a few decades of years. Consequently, stumpage now worth "S" dollars per thousand feet will be worth at "x%" rise, after "n" years, Sxl. Ox^. The present value of such stumpage, to be harvested after "n" years, ia discounted backwards at "y" per cent, and amounts to SXl. Ox° 1. Oyo FOREST FINANCE In place of this terra, it is permissible to write: S 1. 0(y — x)° provided that "x" and "y" do not exceed, say, 8% and provided that the per- iod of calculation does not exceed 100 years. Mathematically, the substitution is incorrect; for practical purposes, however, it is permissible within certain limits. If X equals 4.7% and y " 3% and n " 100 years, the mistake made by the "short cut" equals 5.2%. The mistake increases: (1) With the increase of the price percentage (x) and discount per- centage (y). (2) With increasing discrepancy between price percentage (x) and dis- count percentage (y) ; (3) With the increasing number of years (n). Generally, the mistake does not exceed 5%. An advantage of the "short cut" is the larger scope it offers to financial imagination or to differences of opinion relative to the rise of stumpage prices or relative to the proper rate S SXl. OS-^ of discount. Thus, might be interpreted as or as 1. 03° 1. 08° SXl. 04° SXl. 03° or as 1. 07° 1. 06° "THE BASAL RATE OF INTEREST IN AN EQUATION MAY NOT REP- RESENT THE DIVIDEND WHICH THE OWNER EXPECTS TO DERIVE FROM HIS INVESTMENTS." In the cases just given, the investor will realize 8% if stumpage prices rise at 5% ; 7%, if they rise at 4% ; 6%, if they rise at 3% ; or only 3%, if the stumpage prices do not rise at all. If the prices are increasing at the SAME rate at which the values are discounted backward, the summary of the pre-values is (for annuities as well as for intermittent rentals), nXR. l.op°» mth year: l.op^ 2mth year: R Summary = nXR. Obviously, the summary of prevalues, in this case, is C30 for indefinite rentals. It is unreasonable to suppose, that prices will ALWAYS rise and continue to rise. 10 FOREST FINANCE The growth of trees expressed in dollars and cents is composed of the following factors: A. — Increase of volume, due to the annual formation of a new ring or, better, of a new coat all over the old body. B. — Increase of value, the larger diameter fetching a higher price per thousand feet board measure than the smaller diameter (difference in value of different sized logs at the same time). C. — Increase of price (difference in price of the same sized logs at dif- ferent times), due to an increase of population, to increased logging facilities and to waning supplies. The forester speaks of the volume increment, the value increment and the price increment of a tree; and of the volume increment percentage "a.%", the value increment percentage "b%", and the price increment percentage "c%" of a tree or of a forest. Thus, a tree now worth "S" dollars is worth after "n" years SXl.Oa° Xl.Ob'iXl.Oc^; which term is almost equal to SXl.O (a+b+c)^ In the case of young and sound timber all percentages can be assumed to range between 1% and 4%. In the case of primeval timber of large diameter, volume and value in- crement is insignificantly small. On the other hand, primeval timber is getting scarce so rapidly (walnut, cherry, white pine, yellow poplar, white oak) that a large price increment percentage can be depended upon. Learn to differentiate between the merits of investments in first growth and of investments in second growth!! An interesting case of a declining VALUE increment may be found in hickory poles at a time at which they begin to form heartwood; or in poplar poles at a similar time, when they begin to be less fit for match stock or for fibre. An interesting case of declining PRICE increment (aside of panics, aban- doned use of given woods, replacement of one species by another, change of tariff, export prohibition, Panama canal) may be found in small trees left by conservative lumbering. These trees had a better value BEFORE than AFTER the breaking up of the means of transportation. PARAGRAPH IV.— RECEIPTS AND EXPENSES IN FORESTRY. I. — The revenue in forestry may consist of: — A. — Yields derived from sale or lease of forest pasture; from hunting privileges; from water privileges (power or reservoir); from mines, quarries, peat bogs, etc.; from turpentine and maple sugar orchards; from tan bark, cork, mosses, grasses, pharmaceutical herbs, litter, nuts, seeds and so on. B. — Increasing volume of growing stock; increasing value of growing stock and of soil without any lumbering (so-called latent yields). C. — Usually, during and after the installation period, yields obtained from sale of wood products, notably, FOREST FINANCE 11 (a) Stumpage (French system) ; (b) Log yards (German system) ; (c) Manufactured products like lumber, staves, shingles, telephone posts, ties, blocks for carriages, pulp wood, tannin, fence posts, etc. (American system). II. — Timber yields are ascertained by : — A. — Cruising or valuation surveys. B. — Yield tables (applicable only to even aged and pure forests, fairly well stocked). C. — Volume tables (applicable only to sound trees). D. — The increment percentage. In the United States, reliable statistics relative to the growth of the forests — especially of second growth — and of the trees are badly lacking. ni. — Present timber values. The present values of timber (stumpage values) depend, for a given species, on the expense now required for its utilization, — notably on the charges for transportation which are governed by: A. — Distance from the market. B. — Availability of water, ice, snow, railroads and public roads as means of transportation. C. — Volume of stumpage per acre and volume on the entire tract. D. — Quality of the logs (percentage of firsts and seconds, common, cull, mill cull, etc.). £. — Climatic conditions (malarial climates, long and cold winters, short logging seasons). F. — Specific gravity of timber. In the far backwoods, stumpage even of the best trees frequently has a negative value. Near the market, even utterly poor trees assume a positive value. IV.— Future Timber Values. The study of future timber values is of paramount importance with the forestal investor. Similarly *^he capitalist is interested in the advancing value of real estate, the coming J .idends of railroad stock, etc. He must consider A. — For a country : The probability of a general change of timber prices due to: a. Competition of metals and stone (building stone). b. Waning virgin supplies. c. Importations from Canada, the tropics and Europe. d. Increasing population. e. Coming prosperity or coming depression of all industries. f. New uses of timber, especially in the spinning and weaving in- dustries, in the food industries, in the production of alcohol. g. Wages rising or dropping. h. Gold standard. i. Automobile traction. 12 FOREST FINANCE B. — For a species: The possibility of price alterations in favor of or to the detriment of a species locally prevailing (chestnut in Pisgah For- est; spruce in the Adirondacks; cottonwood in Arkansas; remember laws causing the price of wood-alcohol to drop from 67c to 39c per gallon in 1907.) C. — For a locality : The chances for improved access to a special market by improved railroads, improved navigation (Panama canal), and improved public roads; the chances for the opening of new local markets, or for enlarged foreign markets. Opinions relative to future developments necessarily differ in forestry as well as in agriculture, railroading and industrial establishments. On ex- change, such fluctuations and such diversity of opinion are particularly pro- nounced. V. — The expenses in forestry are : A. — Ordinary or running expenses, viz., 1. Outlay for logging and milling; 2. Administrative expenses; 3. Taxes; 4. Protective expenses; 5. Maintenance of boundaries and land marks; 6. Natural or artificial reforestation (this expense equals, in Ger- many, from 10% — 20% of the net stumpage values annually disposed of); 7. Forest pedagogy; 8. Up-keep of investments, notably of the means of transportation (this expense equals, in Germany, from 5% to 15% of the net stumpage values annually disposed of). Many of these ordinary running expenses must be considered, during the installation period, as extraordinary investments. B. — Extraordinary Investments. 1. Soil and, usually, trees. 2. Permanent means of transportation. 3. Wood working establishments. 4. Buildings, farms, pastures, ochards. 5. Surveys and working plans. 6. Fire lanes. 7. Fences for pastures, game, etc. 8. Afforestation. Al! over the world, but especially so in the United States, the capital now invested in a forest is not that which promises to yield the highest rate of int- erest for the next period of years. The principal investment requires addi- tions here and reductions there. The time at which alterations should be made depends upon local factors as well as upon personal opinion. The components of the final investment in conservative forestry are those enumerated under B.— Naturally, there is no need for all of them to be at hand in every case. The share which each component takes or should take FOREST FINANCE 13 in ths aggregate investment, again depends upon local conditions and upon personal opinions. Forest investments, in this connection, do not play any exceptional part. In agriculture, e. g., the final investments are composed of soil, improvements, roads, clearings, live stock, machinery, buildings, etc. Likewise, mining in- vestments do not consist of mineral soil merely; but, in addition to soil, of machinery, buildings, railroads, shafts, etc. A forest must be considered "normal" when the investment which it rep- resents has reached, for the time being, in the owner's opinion, the highest stage of relative remunerativeness, with all of its (the investment's), components balancing in proper equilibrium. Naturally, the owner alone can decide whether this stage is act'ially reached or not. PARAGRAPH V.— TAXES. In America taxes usually depend upon the market value of a taxable object and amount, in the wooded states, to about 19c ad valorem of the same. If the market value '"V" of a given forest grows at the annual rate of "x%" during 'n'' years, the taxes (theoretically at least) increase likewise at the rate of ''x%'\ They accumulate at the rate of "p%" in such a manner as to amount, at the year "n", to the sum total V 1.0x° — 1.0p« X Xl.Ox (M) 100 l.Ox — l.Op Case I: x equals p Then the aft-value of every single tax payment equals, V (1.0x1) 100 The summary of the aft-values equals n \ [l.Ox° /lOO \ or n% of the forest aft-value (which is VXl.Ox°). Thus, if "n" equals 25, the taxes consume }i of the aft-value; if "n" equals 100, the taxes consume the entire aft-value. Case II: x is smaller than p Then 1.0x° is much smaller than 1.0p° ; the summary is much larger than V (1.0x°) or much larger than 100 n the part of the forest aft-value. 100 Thus, if "n" equals 25, the taxes consume more than }:{ of the aft-value; and if '"n" equals 100, the taxes consume more than the entire aft- value. 14 FOREST FINANCE Case III : x is larger than p n Here the taxes consume less than the part of the aft-value, e. g., 100 ' ^' if "n" equals 25, the taxes consume less than 3^ of the aft-value; and if "n" equals 100, the taxes consume less than the entire aft-value. Deductions from the above: — RULE I. Destructive forestry is indicated where a long number of years is expected to elapse before a second cut can be obtained; where taxation ad valorem is high; where the value of the forest grows slowly (x being smaller than p). RULE n. The forester, bent on forest conservation, must endeavor to shorten the period of waiting between cuts by leaving sufficient stumpage and sufficient means of transportation to allow of frequent cuttings within the same forest. RULE m. The damaging effect of taxation depends pre-eminently on the period of waiting; the rate of interest being more irrelevant, "x" being usually equal to or close to "p". After the wholesale removal of the primeval forest, the period of waiting is excessively long. The forester's activity should be called upon before and not after the first inroads of the axe into the primeval woods. PARAGRAPH VI.— PROTECTIVE EXPENSES. The influence exercised on the prospects of conservative lumbering by expenses for forest protection is analogous to the influence of taxes. The decision whether and what protection should be given to a forest, solely rests with the owner. The following may illustrate the influence of the protective expenses on a forest conservatively managed: FIRST. An unprotected forest, "V", may yield an annual net surplus revenue "R" as long as it escapes fires and theft. R y equals or lOOR equals yV V 100 SECOND. Sacrificing annually "D" dollars for protection, the owner retains a revenue, "R — D", and the interest percentage "y" is reduced to "z" per cent., whilst "V" remains much unchanged as long as no fire happens to occur. 100 FOREST FINANCE 16 THIRD. Hence and D y -z R y If D eqtials 8% of R Rs equals lOOD s y — z then and 100 (N) (O) FIFTH. For "y" ranging from 2% to 8% and for "s" ranging from 5% to 30%, the percentage of net revenue "z" is reduced as appears in the table following:— s equals 5% lO^c I 16% ..-, 25% 30% y equals 2 | 19 1.8 j 1.7 | 1.6 1.5 1 14 y - 3 1 2 85 1 2 7 2 55 | 2 4 2 25 i 2 1 y " 4 1 38 ! 3 6 1 3 4 i 3 2 3.0 2 8 y •' 6 1 4.76 1 4.6 ! 4.25 j 4.0 3 75 1 3 6 y " 6 1 5.7 1 8.4 1 5.1 1 4.8 4.6 1 4.2 y •• 7 1 6.66 1 63 j 5 95 | 5 6 5.26 1 4.9 y •• 8 j 7.6 j 7.2 i 6.8 j 6.4 6 1 6 6 In the case of a forest which does not yield an annual surplus revenue, the influence of the protective expenses is somewhat different from the above, as is illustrated by the following considerations: — FIRST.

PARAGRAPH VII.— CAPITAL AND MONEY. A. Any object or thing having earning power is a capital. By "earning power" is understood the power to furnish commodities coveted by man. B. — "Money" is not "capital"; it is merely the "legalized measure of values", and hence frequently the measure of "capital". Different countries legal- FOREST FINANCE 17 ize or use different units of measure, and within the same country, time causes the unit to vary (cattle in the United States; platinum in Russia; silver in some of the Latin countries; glass pearls with the Indians; courie shells with the Siamese). Money, in other words, is nothing but a unit of measuring, having func- tions like those of the yard, the bushel, the pound (all being subject to fluc- tuations) to wit, the functions of measuring. C— All production originates with nature, and all capital consists, in part, of natural creations or natural objects, namely: 1. Natural gifts (soil and soil products) ; 2. Natural forces (wind, water, fire, gravity, electricity, heat, rainfall). D.— Accumulated human labor forms, usually, a part of a capital actuaUy producing (field, wind mills or water mills). E.— Merely natural capitals to which no human labor (accumulated) is at- tached, are usually unproductive; although their earning power might be at hand (most of our waterfalls; the prairies a century ago). Mines and fields, without the addition of accumulated labor, cannot prove their earning power. The forest and the pasture— under certain conditions at least and for limited periods— may create new commodities without requir- ing labor to be previously performed. < . ,, F —As long as the population increases, the individual's share in the "gifts and in the "forces" of nature— especially in the gifts— DECREASES and the units of such gifts and forces increase in value. On the other hand, capital consisting largely of accumulated human labor depreciates under the same circumstances. The more a capital consists of- {^^^^::^ade}-'=°"'P°'''"*'' ^^' ^'"" are its chances to gradually- |">®jj } —in (exchange) value. Rule a. As long as capital, labor, population and money in circulation re- main the same, values remain the same. Rule b. If capital alone decreases (population, labor and money stagnating) less products are available and $1.00 can buy less products or less capital than heretofore. (This rule holds good, especiaUy, in the case of the necessities of life.) Rule c. If population alone grows (capital and money stagnating), $1.00 can buy less natural products or capital than heretofore and can buy more man-made capital or products than heretofore (since labor is cheapened). Rule d. If money alone increases (population and capital stagnating), $1.00 can buy less products, labor or capital than heretofore. As a matter of fact, population and circulating money are on the increase in the United States, whilst capital consisting of natural gifts is decreasing and whilst capital consisting of natural forces remains the same. H.— All economic factors combine as a consequence to continuously lessen the purchasing power of the dollar in the United States. The legalized 18 FOREST FINANCE measure of value getting shorter in its effect, the number of units of value (or dollars) equalling a capital or a product increase necessarily. I.— Gold. The world's production of gold (the money of the leading nations) has increased and continues to increase at an alarming rate. This increase has had the tendency, unavoidably, of cheapening gold, or of reducing its power to purchase other goods. If man were actually to realize the enormous increase of the production of gold, the decline of its purchasing power would be more patent — it would become acute. A commodity (gold is a commodity like silver or iron or wheat, after all) drops in value at a time when it is known (or supposed) to be produced in excess of the demand; — not at a time when it actually happens to be excessively produced. In the case of gold, in the author's opinion, mankind has not begun to realize the enormous increase of the supply; and it is far from anticipating a still more gigantic increase of the supply in the near future at a time when new technical and chemical methods of "gold making" come into play. A demoralizing "slump" in our entire monetary system is unavoidable as soon as gold can be produced at a greatly reduced expense of labor. The knowledge of a slight over-production causes the price of cereals and cotton and lumber to decline perceptibly; similarly, the knowledge of a slight excess production of gold must cause its depreciation. In the past decades, this depreciation has been prevented by a number of countries rapidly adopting the gold standard and accumulating gold in their treasuries. In the future, this depreciation must be marked. If the purchasing power of gold decreases at the rate of 2% per annum (and the author anticipates a more rapid decline), the consequences will be: a. for the possessor of bonds, mortgages, life insurance policies, etc., a heavy loss of capital as well as of interests. b. for a "country of bondholders", and therefore pre-emmently for European countries, heavy losses; c. for "countries of stockholders", and countries rich in pastures and forests and farms, a decided superiority over others not so blessed. A man owning 4% bonds rated at par will do well — if he desires to remain equally wealthy — to consume not over 3-^ of the interests obtained and to re- invest the other 3^2 with a view to counterbalancing the tendency of gold to depreciate. Conclusions. A man owning $100,000 cash in 1908 is less wealthy than the man owning the same amount in 1898. A man who has let out, in 1898, $100,000 and who has consumed in the meantime all interest derived therefrom, is getting less wealthy. He should have saved a portion of the interest actually obtained adding it to the original $100,000. FOREST FINANCE IS On the other hand, a man letting out, in 1898, 10,000 acres of land and retaining them in 1908 in equal productiveness, is absolutely as wealthy now as before; relatively wealthier than before, although he was allowed to con- sume all interest or revenue obtained from the lease. PARAGRAPH VIII.— INTEREST. I. — Definitions. A. — Interest (gross) is the price paid for the use of capital. B. — As freight is the price of "site-difference", so is interest the price of "time-difference". C. — Net interest is the difference of a capital's "earning power" at the beginning and at the end of a season plus the value of the product in the meantime produced by capital and not by labor. D. — Interest may mean either the net or the gross product of capital, i. e., of any object having earning power. E. — The price of the use of labor equals the value (of product, or of capital) which the employer hopes to create thereby. The price of the use of capital equals the value (of product, or of new capital) which the employer hopes to create thereby. F. — Interest is the product of capital; its price is the price of the product I In loans of capital, it is usual to loan the "measure of capital" (gold) and to turn over to the owner thereof the "measure of the product" (gold.) The borrower may use a loan to pay WAGES and in that case he ACT- UALLY borrows LABOR, reconvertmg "ACCUMULATED" labor into "RUN- NING" labor. n. — Gross Interest on Money Loans. This is the product of capital employed in another man's production. It consists of the following parts: — a. The true, net, actual, clear yield of capital "{%&)". b. "Risk quota", or remuneration for risk taken, or capital secretly repaid, or capital apt to be consumed in the course of the pro- duction. This quota is meant to rebuild that much of the origina capital as is iiable to incidental destruction "(^b)". c. Remuneration for labor, financial sagacity and discomforts requiredl from the owner in harvesting the yield of capital "(^c)". d. Quota which must be saved and added to the original in order to allow the owner to remain equally wealthy whilst the purchasing power of money declines "(td)". The investing capitalist invariably over-estimates the true or net yields of his investment ("^a) and proceeds to consume Cb) and (*!d). Few families remain equally "wealthy" in the long run excepting those owning entailed real estate. in. — Interest on merely natural investments (farms) consists of "(fa)" and of "(lie)". The risk "(^b)" is little since the soil, at least, is safe. There is no "iW"- 20 FOREST FINANCE IV. — Interest on capital consisting of accumulated labor has a very large "(^b)". This is proven by the following: — 1. It can be outranked and reduced in value by other and better labor- accumulations (e. g., sulphite fiber process superseding soda fiber process; Southern cotton factories outranking Northern cotton fac- tories; steamships superseding sailing craft). 2. The real necessities of life are more a soil product than a labor pro- duct. In the case of unnecessary articles, fashions and inventions cause continuous fluctuations of the remunerativeness of the in- vestments producing such unnecessary articles. 3. If a production, basing largely on accumulated labor, is found to be remunerative, it is at once overdone; and competition kills the yields (e. g., bicycle manufacturing). 4. Labor-made capital (machinery) is usually consumed in the course of the production. V. — It may be said that no man who wishes to be on the safe side, on an aver- age, should annually consume over 2% on his investment; or that no man should rate the true earning power of his investment at a figure exceed- ing 2%. The financial genius, of course, can do better and can credit himself with a large "(lie)"; he foresees the development of the future correctly; at an outlay of $1,000, for instance, he creates or acquires a capital producing $100 of true net "{%&)", which is worth $5,000. Thus, he owns five times as much as before at the end of the production. * Theoretically, the genius obtains wealth by buying productive capital actually under-rated by the majority of the owners, and by selling productive capital actually over-rated by others. The blunderers foresee the coming events wrongly; they sell on a rising market, and they buy on a falling market. During the year, the investors change their opinion frequently, relative to the outlook of the future; hence continuous fluctuations on exchange. The ratings placed by two men on the same investment coincide in rare cases only; hence few transactions on exchange, a trade being made only when two men happen to agree. VI. — Additional factors influencing the rate of interest: — 1. Unhandy credit systems; 2. Partial or slow courts; 3. Danger of foolish legislation; 4. Amount of indestructible assets. The factors 1, 2 and 3 increase, and the factor 4 decreases the rate of interest. The rate of interest charged for loans and bonds increases whenever the industries prosper. The available money is then withdrawn from loans and put into industrial engagements. VII. — Limits of Interest. 1. The lowest limit is the figure at which the owner prefers to hide or consume his belongings. FOREST FINANCE 21 2. The upper limit is the actual effect of the investment for which means and bounds do not exist. If the investment cannot be duplicated (Standard Oil), the rate of interest becomes a personal matter being governed by the capitalization which the owners choose to adopt. Vin. — The net or true interest 1. has the tendency of equalization A. in loans, because interest is merely the price of such loans re- sembling the price of any other commodity; B. in investments, because universally remunerative investments are soon over-crowded by competition where duplication is pos- sible. Where this is not possible, there abnormal revenue is at once capitalized, the new capital value being added to the ori- ginal ("watered investments"); 2. has the tendency of sinking because the wealth of the nations is rising at a faster rate than the chances at remunerative employment of wealth. IX. — Justification of Interest. 1. The Church, since 325 A. D., has condemned interest after Luke VI : 35. In the early Christian era, loans for consumption only were known, not loans for production. 2. After Adam Smith, the capitalist would not care to take any risk, temporarily parting with the full control of his property, if he did not see any inducements. 3. After Senior, interests are payments due to the owner for abstaining from the immediate consumption of his property. 4. After Marx and La Salle, interest is cut-off from the wages properly belonging to the wage earner. 5. Merely natural capitals (deer, buffalo, trees, grass lands) produce annually. Thus, interest on capital is natural, — is part of the econ- omy of nature. X. — Rate of Interest in Forestry. 1. Conservative Forestry. a. There is no "(Hb)" or "(Hd)" to be deducted from the gross rate of interest, since there is no risk and no influence on the investment due to the declining purchasing power of money. b. The rate of interest compares favorably with agricultural interest because the products of the forest can be stored free of cost, and are exposed but little to drought, inundation, boll weevil, etc. If the products are killed by storm, fire and insects, forestry can bring them to the market, usually, at a scarcely reduced price (see American Lumberman, September 19, 1908). The rate of true interest in conservative forestry is about 23.^% (in Sax- ony, on an average for the year 1905, 2 Vlo% ; see Thar. Forst Jahrbuch, 1907, 1st issue.) and compares very favorably with 4% on bonds and 6% on industrial investments. 22 FOREST FINANCE 2. Destructive Forestry. The net revenue cannot be separated easily from the capital gradually withdrawn from the forest. If only soil (S) remains after complete exhaus- tion, within (n) years, of a forest of the original value (Q) whilst surplus re- ceipts, Ri, R2, R3, etc., are obtained during the (n) years of destructive lum- bering, then the rate of interest, (x), is illustrated by the following equation : — QXl.Ox>i=Rl (1.0x°-l)+R2 (1.0x'i-2)+R3 (1.0x'>-3)+ . . . Rn + S. XI. — Saxon Statistics show: — 1. That the State forests have paid, since 1816, 2% net on the annual average. 2. That the money value of the forest, since 1816, has risen by 3% on the annual average, a rise largely due to the declining purchasing power of gold and partly due to improvements and additional in- vestments. Xn. — The decision in the problem confronting the owner: "Shall I practice conservative forestry or destructive forestry?" must be based on the true rate of net interest obtainable from the one and from the other. It re- mains for the forester to demonstrate the difference between net interest and gross interest. The chances for conservatism in forestry to be superior to radicalism are, on the whole, extremely good and especially so in the United States, since 1. The American lumber market is almost continuously overstocked beyond its digestive capacity. The virgin supplies are being ex- hausted, and are apt to be entirely exhausted by 1950. In the mean- time the stumpage prices of all good timber must increase steadily. 2. It must be remembered that the now wealthy lumbermen have made their wealth by buying stumpage when and where it was under- valued and by holding it for a number of years. Fortunes have never been made by any particular skill in lumbering, milling or sale of lumber. Strange as it may sound: Inactivity has paid better in the case of in- vestments in American forestry than hard work spent in lumbering and milling. There is no reason to anticipate that the future will materially differ from the past. XIII. — Interpretation of the rate of interest on which a calculation is based: X 1) The sum may mean l.op° a) that the calculator expects with a faith in his forecasts expressed by p% receipts or expenses (X) to occur (n) years from date of calculation, or b) that the calculator expects, with a faith in his forecasts approx- imated by (p+y), receipts or expenses X or XXl.oyo l.oy° to occur n years from date of calculation. FOREST FINANCE 28 This possibility of interpretation allows of the expression of widely dif- ferent forecasts by a mere change of the rate of interest underlyiag the cal- culation. The basal rate underlying an equation does not or need not design- ate the actual dividend expected by the calculator. It is the mathematical outcome of his fears and his hopes, of gloomy and of rosy anticipations. PARAGRAPH IX.— EXPECTATION VALUE. The actual value of any object to its owner, or to anybody else (cow, house, railroad bonds, mining stock) equals the pre-value of the expected ser- vices or yields, duninished by the pre-value of the expected expense required to obtain such services or yields. Obviously, the rate of discount is of para- moimt importance relative to the result of the calculation. 'Individual opin- ion" governs the rate of discount as well as the anticipations^of future events. Values rise with the expectation of rising yields, of sinkmg expenses and or reduced rates of interest, and vice versa. Obviously, the selection of the rate of interest, and the forecasts of future yields and expenses, depend, above all, on personal opinions which may be pessimistic or optimistic, bearish or bullish. Applied to forestry, we find the following expectation values: 1. Value of a regular second growth forest (m) years old: thna thnb thuc f.c. i-s.v. +V + + + V 1.0p«-™ l.Opb-m l.Op'^-™ l.Op'^-™ wherein thna, thnb, thnc stands for thinnings in the year a, b, and c of the forest; f.c, for value of final cut; s.v., for soil value after final cut, and V for a perpetual rental defraying taxes and admini- strative expenses reduced by annual receipts for leases, etc. 2. The value of bare, absolute forest soil, planted up at an expense of "pig" and weeded at an expense of "weed" equals thna X LOp*"-* + thnb X l.Op'^b + f .c— pig —weed X l.Op'"™ V— pig (l.Op^-1) 3. The value of an ideal forest in which all age classes are present, which is conservatively managed, close to a ready market (so that in every year of the future there may be obtained a yield from a thinning in a woodlot "a", ''b", "c" years old and also a final yield diminished by reforestation expenses, whilst the expense of administration is an- nually "v" for the entire forest) amounts to thna +thnb +thnc + (f.c— pltg) — v in which O.Op thn equals thinnings p " rate per cent. f.c. " final cut pltg " planting. 24 FOREST FINANCE PARAGRAPH X.— SALE VALUE OF WOODLANDS IN U. S. It is customary to buy timberland merely at the price of the stumpage standing thereon. The purchaser neglects: C / 1) that he can not cut all of the timber at once; and such parts, as ■5 \ he cuts only after some years, should not be assessed at full value ; *" j 2) that taxes, etc., accrue, whilst the timber is cut gradually; > \ 3) that an expense for legal and timber investigations must be covered; g, / 4) that timber values might be destroyed by fire; K I 6) that there is danger of fool-legislation against alien corporationg. a) that soil has value; b) that stumpage prices (and merchantability, hence volume) will increase ; c) that there is a second growth already at hand; d) that local means of transportation increase; e) that taxes might be decreased, and that protective legislation will come; f) that freight rates decrease; g) that population increases, also demand; h) that new uses are found for wood ; i) that investments in forestry are remarkably safe, compared with stocks, bonds, etc. j) that the agricultural value of the soil increases, absolute forest soil becoming absolute farm soil, as the years go by; k) that forest pasture, chase, minerals (rock, clay), waters and water- powers promise an increasing revenue. PARAGRAPH XI.— GAUGING THE MERITS OF AN INVESTMENT. The Success of a business (in farms, mines, forestry) is evidenced by its net gains. Expenses and yields can be compared either by forming their difference which comparison shows an "entrepreneur's" gain or loss; or by forming theu- ratio which method shows the actual dividend obtained from the business. I. — Entrepreneur's gain and loss. Influencing factors are: — a. Lapse of time. b. Constellation of economic conditions. c. Personal foresight. d. Rate of interest introduced into the calculation. An undertaker's gain may be figured out retrospectively or prospectively. An undertaker's gain is fictitious until, the property changing hands, it can be demonstrated to be a fact. FOREST FINANCE 28 The undertaker's gain or loss disappears when the financier introduces a rate of interest at which the discounted expense equals the discounted yields. n. — The forest dividends show what actual rate of interest the owner has made in the past or may earn in the future on his investments. The actual rate of interest introduced in the financial equation causes any undertaker's gain to vanish. The forest dividend is deeply influenced by the price increment of trees (improved means of transportation; enlarged markets, etc.) In the forest, it is difficult to distinguish between actual revenue drawn from the forest and capital withdrawn, since the trees are capital as well as product. In conservative forestry, careful stock taking is required period- ically, so as to show the actual status of the investment. PARAGRAPH XII.— MATURITY OF TREES. I. — In the botanical sense, wood fiber is mature almost after the conception of the cell. A tree 3 inches in diameter is physiologically just as mature as a tree 3 feet in diameter. The highest stage of botanical maturity is the so-called heartwood. II. — From the people's standpoint, timber must be considered mature at a time at which it is best adapted to general usage in the wood consuming industries. The older the tree gets, the larger is, on the whole, its diver- sity of utility. The rotation best adapted to supply the industries of a country is called the "technical rotation". in. — The sylviculturist regenerating the forest from self-sown seed cannot select a rotation which does not allow the trees to profusely propagate their kind. In coppice woods, since the sprouting capacity decreases with increasing diameter, the rotation must be so low as to allow of luxuriant production (sylvicultural rotation). rV. — From the financial standpoint, trees or forests must be considered mature when the net true interest obtained from them ceases to bear a sufficient ratio to the sale value of such trees or forests. Wherever the woods are stocked with even aged and even sized trees, all of the trees reach maturity at or about at the same time. The primeval woods of America do not exhibit, usually, such even aged conditions. The American forester had better speak of the maturity of trees than of the maturity of forests. Factors influencing the maturity of trees in America are, pre-eminently : — a. The price increment, which, in the case of large trees, far exceeds the volume increment and value increment. Stem analyses and volume tables are of little value, consequently, for the financial diagnosis of primeval trees. 26 FOREST FINANCE b. Means or arteries of transportation and the permanency of their char- acter. Where the means of transportation are considered as a permanent investment and not as a temporary expense to be re- imbursed by current operations, a higher age of maturity results naturally. c. In many cases the taxes per acre are not or are scarcely influenced by the severity of the cut. Here it is irrelevant, from the tax payer's standpoint, whether he proceed to log certain sizes or kinds of trees or not. Where, on the other hand, taxes are changed ac- cording to the stumpage found per acre, the standing tree must be charged with that much of the tax per acre as corresponds with its individual contents. Take, e. g., a forest of white pine contain- ing 5,000 ft. per acre consisting of 12 trees averaging 400 ft. b. m., taxed at 30 cts. per acre. The soil has little value. A tree con- .30 X 400 taining 400 ft.b.m. must annually defray =.024, which 6000 expense of .024 must be charged against the tree and must be de- frayed from the annual increase, if any, of the value of the tree. d. Trees acting as mother trees propagating their kind should be credited with the prospective value of the progeny produced by them, on an average. On the other hand, trees acting like weeds and re- tarding the growth of a younger progeny of seedlings and saplings beneath them must be charged with the loss of prospective incre- ment incurred by such second growth. e. Since protective and administrative expenses are governed more by area than by the density of the stands, it is necessary in rare cases only to charge a pro rata of the protective and administrative ex- penses against the individual tree. These expenses incumber the soil like prescriptive rights. f. The question of maturity is a question to be answered in the first and last instance by the owner who is governed by his personal attitude regarding the rate of interest obtainable from his invest- ment; by the prospects of price increment as they appear to him and by personal moments like the lack of cash to defray running expenses, mortgages, etc.; chance of remunerative investment elsewhere; desire to distribute risks; tastes and predilections. Trees of defective character infested by insects or fungi have reached maturity, generally speaking, since the spread of the disease checks their financial increment, and may cause the increment to be negative. V. In Europe the following number of years denote, on an average, the ma- turity of timber: pine 100 yrs.; spruce 90 yrs.; fir 120 yrs.; beech 120 yrs.; oak 160 yrs.; oak coppice 18 yrs.; willows 1 and 2 yrs. In America, naturally, fixed rotations have not been adopted, since the cutting takes place, usually, in the primeval woods. In Virginia, a second and third growth of pine is cut under a rotation of about 60 years. Catalpa FOREST FINANCE 2T is coppiced under a rotation of about 10 years. The very prime trees, notably hardwoods, of a primeval wood are immature from a financial standpoint, if the owner believes that the greatest advance in prices will come to them, such giants getting rare and more rare, year by year. In many cases, the price of inferior stumpage does not promise to rise as much as the price of prime stumpage. On the other hand, in many a case, the indicating percentage of trees promising a large percentage of "cull lum- ber" is manifestly superior to that of trees containing a large percentage of "fas lumber". In Europe, the question of maturity is largely a question of age or (which is almost the same) of diameter. In America, on the other hand, the question is one of conditions — condition of transportation, danger from fire, condition of health, the chances for their improvement or deterioration. Thus, a diam- eter limit or age limit can scarcely denote maturity. The American forester in charge of large districts is confronted many a time with the necessity of treating individual trees according to their financial merits, whilst his Euro- pean colleague in charge of small ranges has to deal with even aged aggre- gates resulting from second growths. VI. — The term "indicating percentage" denotes the current dividend obtain- able from a tree or woodlot. This percentage indicates the maturity of a tree or of a woodlot. A tree or woodlot is mature and should be removed when it ceases to yield (latently, of course) the dividend desired by the owner. The owner or investor discards an investment in forestry as well as in stock when the dividend seems to fall below the limit obtainable by him in other enterprises of similar safety. If he discards at the right time, he will make money; and otherwise not. In the following remarks, the indicating percentage is called "x"; the forest percentage denoting the "limit" just mentioned is called "p". Previous to maturity, "x" is larger than "p"; at maturity, "x" equals "p"; after maturity "x" is smaller than "p". The indicating percentage of a woodlot, for a period of 10 years, is as follows, if the stumpage is now worth "S.S." dollars; if it is worth, after ten years, "S-S^g"; if the cleared soil is worth "C" dollars; if administration and taxes are "v" dollars per annum, forming an administrative capital "V": — (SS + C + V) 1.0x10 - SSio + C + V or (1.0x10—1) (SS + C) 1.0x10 +v -C+SSio O.Ox According to Krafft, the indicating percentage had better be considered as a dividend on stumpage merely v/hilst the soil and the administrative cap- ital should yield the forest dividend required by the owner. Krafft's "x" is more sensitive than the "x" commonly applied since it bears a ratio to part of the investment only. Krafft's "x" is found asfollows: — SS X 1.0x10 + (C+V) 1.0plO= SSio + C+V as FOREST FINANCE In conservative logging when a portion only of the trees are removed from •very acre, the indicating percentage had best be considered as a tree dividend. Whether and how much of the taxes and administrative expense (e) should be charged to the tree, depends upon the local circumstances. Trees occupying soil and preventing, by their presence, a second growth from de- veloping, must be charged with the interest on the value of the soil thus oc- cupied. On the other hand, trees acting as mother trees must be credited with the value of the progeny resulting from their presence. The tree indicating percentage might be expressed, adopting Kraflft's method, as follows : (l.Opn— 1) To X 1.0x°+e + (soil) 1.0p°=Tn + soil + value of progeny O.Op in which "Tq" equals the tree value now. Where the forest stocks on agricul- tural soil, all trees unable to defray the interest on such valuable soil, appear to be mature, or hypermature. VII. — The forester making a working plan for pine and spruce woods is usually confronted by the question of the best diameter limit. The plan advises the owner as to the limit yielding the highest entrepreneur's gain or the highest forest dividend. The heavier the present cut, the smaller is the investment left, whilst the protecting expenses remain the same. On the face of it, it seems unwise to cut clear without considering the financial prospects of trees which might be left on the ground, having 10", 12", 14", etc. in diameter. Obviously, the logging expenses per M feet b. m., are smaller in the case of heavy cutting, than in the case of light cutting, particularly so when the logger must avoid any damage to the trees left standing. Again, obviously, the longer the period of waiting for a second cut, the less are the chances for a good return from conservative logging. The diameter limit might be tested either with the help of the indicating percentage or by the method of the entrepreneur's gain. INTEREST TABLES (EXPLANATORY) Column I indicates the number of years.
