INTRODUCTORY. 1. WHAT REGULATION TRIES TO DO. The task of Forest Regulation is: To build up;Put in order,and Keep in order a forest business. a) In the United States the task is to take a piece of Wild Woods and convert this gradually into a forest business which shall produce timber, as much and as good as the land and climate permit, and to have this timber in such a condition of age and arrangement that a crop may be cut each vear, and thus an income secured in keeping with the investment. To accomplish this, Regulation not only orders in time and place. the work of Silviculture, the planting or reproduction of the stands of timber and their care, -ut it also plans an orderly harvest of these stands of timber, and plans the necessary improvements, division into suitable parts, necessary roads and other means required to enable satisfactory Protection and Utilization of the forest. Regulation plans the work on the forest: Administration car- ries out the plans. But these two branches of Forest Management are never sharply separated. b) Regulation depends on many conditions. It must consider the land and timber it has to work with to raise the crop, and it must consider market, transportation and labor which decide the value of the crop after it is raised. But Regulation is especially dependent upon Silviculture and their relation is interesting in this connection. Silviculture studies the hest methods of raising the stand of timber under the various conditions of soil, climate and species, and it applies these methods in its work. Thus Silviculture depends on natural (not man-made) conditions, and on natural. laws and to this extent it must not be interfered with by Regulation and Administration. 2 FOREST REGULATION When Silviculture has indicated that a particular tract of land is suited to Spruce, and that Spruce will thrive if planted, thinned and cared for. according to a certain method, its share in Regulation is ended. Then it depends on Utilization and Valuation whether a certain method of planting is sufficiently economical to be planned for by Regulation, whether it is economical to use the method of planting with large transplants, whether it is advisable in this case to thin every ten years, and whether it is best to cut this timber at the age of 80, or 100 years. Regulation, weighing all conditions formulates the plan for Silviculture to follow, and do its best whether the decision is for seeding, planting, or natural reproduction, and whether it is the most effective, expeditious way of raising a stand of timber or not. c) In our country the Forester starts with wild woods; often not even surveyed. In one locality he finds good market for every thing, in another no market at all; usually no division of the forests into convenient tracts, (fields or lots or compartments) ; no roads; no help, no information regarding land or timber, save a few unreliable estimates of the “merchantahle” stuff; no information as to how fast the timber grows, how old it must be before it reaches certain marketable sizes. ‘The job is all new, and in many cases conditions do not warrant doing more than establishing ownership and giving the forest protection. Generally, however, the tendency is to overrate difficulties, and underrate possibilities. In the United States conditions change rapidly; what serves and seems sufficient today is no longer so tomorrow. Railways are building into every nook and corner of our country ; the demand for timber in the United States is enormous and is still on the increase ; the price of stumpage has advanced, in some cases 500% in less than 20 years; large areas of supplies have been entirely exhausted; there is practically no growth replacing our cut. The development of forestry in the United States cannot take the slow way it has followed in the Old World. The tree planted today in almost any part of the eastern half of the United States will bring as good a stumpage as it would in Germany or France by the time it is ready to cut; the forester builds for the future, and this future is safely judged by the best conditions seen in parts of our country even now. It is also safe to judge this future by the conditions existing in the most advanced and most prosperous parts of Europe. INTRODUCTORY 3 d) In Germany, say for the last 100 years, Regulation did not usually start with wild woods, but it found an old business, well established, with areas marked, the forest divided, accessible by roads, with a system of protection, and with records giving experience to build upon. Practically everywhere the Market was established, and the necessity of the work was recognized. Modern Regulation merely established a better system just as modern farm management attempts to help agriculture by improving system. e) But what is such a Forest Business as we wish to build up, and develop? The answer must come from the Old World, and hence the following brief description of a German Forest. 2. A TYPICAL GERMAN FOREST BUSINESS. This “Revier” or Forest looked after by one Forester (Ober- forster) is part of the State Forests of Wiirttemberg, and may be described categorically about as follows: Area: about 8000 acres (3205 hectares) ; nearly all in one body. Staff of men or Organization: one “Oberforster,” or Forester and six Rangers (“Forstwart’). Country: Hilly, and easy rolling, gravel and clay lands; old and well settled, prosperous. Market: Can sell everything even faggot material, average price about 15 cts. per cu. ft. on stump; railway, trunkline, runs through one corner of the forest. Labor: Plenty, but demands fair wages and steady work; numerous factories compete for this. Roads: A complete network of roads, well located and sur- faced with gravel, connects every tract or lot with the main lines and railway. These roads were built and are maintained by the forest itself. Climate: Raw: cold winters, cool wet summers, excellent for timber, and for agriculture; heavy wind storms due to proximity to the Alns. Forest Protection: Good: the six Rangers patrol daily. all year round; the people of the district are not only compelled, but 4 FOREST REGULATION are glad to assist in prevention of fire. No real forest fire here in fifty years; prokably not in a hundred. Division of the Forest: Working Section I. Spruce forest, 85% of entire forest. Method of silviculture: Clear cut and plant, with 5 vear transplants; ripe timber cut at age of 90-100 years; all stands thinned about every 10 years. Working Section I. Beech forest 12% total; Shelterwood method : rotation 120 years. Working Section III. Mixed hardwoods 2% of total on over- flow land; Selection Method, cut over every 10-15 years. Alder grows here to a height of 100 ft. Besides these three kinds of woods, there are a few small patches of hardwood Coppice. mostly Alder and Ash on wet spots, scattered through the forest, which also have their own plan. Land Division: The entire forest is divided into fields or Lots (compartments) generally less than 40 acres in size and separated by cleared lines, or by roads. These Lots are all marked with stone monuments, and numbered. Cutting Series: All over the entire forest, the Lots are grouped in twos or threes, and the lines around each of these groups is made double width or about 30 ft., so that the trees along these lines keep their limbs and form a solid protective border against wind, and also become more windfirm than thev are inside the stands. These groups of two or three (rarely one) lots thus make little independent woods, separated from the surrounding woods, or their neighkors, by wide lines, so that the timber on any one of these tracts can be cut without endangering the surrounding forest. These independent woods (Cutting Series), here in Spruce, are a necessity, for without them the forest would suffer great loss from windfall, if the older stands were opened up by accident or by cutting of timber. Silviculture: ‘I'he methods have been mentioned and the care here is of the best. A nursery on the property supplies all plant stock. Every stand is thinned at least once every ten years. Every acre of this forest is “man-raised,” not one acre is original wild- woods. Age Classes: Old. middle age and young timher occur here in such perfect regularity that there is a crop of Spruce, of Beech and GERMAN FOREST 5 of other hardwoods ready to cut every year, without fail. Having been under good management so long, there is now about the same area of Spruce 1-20 years, 21-40 vears, etc.. clear up to 100 year old stuff. Dut the 80-100 year old timber is not in one body but is in a dozen or more different tracts, scattered over the forest; and this is also true of the young timber. In fact special care is had to prevent large tracts of timber all of one age, since this has been found dangerous particularly on account of windfalls and insects. Cut of timber: Is yearly logged by contract, logging done “by hand”; done by small groups of men regularly employed on the forest; the material cut in thinnings is skidded to the road: where old stands are cut clear, the stems and cordwood are left on the land to be hauled away by the buyer. The timber is cut in long lengths, commonly full length, like telephone poles, peeled, each piece marked and measurements noted on stick. The timber is sold in small and large lots, by auction sale. The thinnings pay well; for instance the thinning of a stand of Spruce 79 years old brought over $80.00 per acre, after paving for labor. The total cut amounts to near a million cubic feet per vear, and is of excellent shape and quality. Income and Expenses: The expenses each year exceed $3.00 per acre. or $25,000 total. Over half is for logging, akout 30 cents per acre is for protection alone; a like amount is paid for local taxes, and about 20 cents for roads. The gross income for years past has been over $12.00 per acre. making a net income of akout $9.00—$10.00 per acre and year or $70,000—$8o,on0 for the forest. ' Working Plans: This forest was in good hands and had good care for centuries. A few old stands testify to the excellence in silviculture of the men working here over a hundred years ago. The present plan was first worked out about 1860, has been revised every twenty years since. At each revision the Forester in charge of this work goes over every lot, examines and notes the condition of every stand. In making the plan he prepares a table. arranging the stands according to age, and picks out enough of these stands to make up the cut of the next 20 years: for the Spruce, then, about 1/5, for the Beech section about 1/6 of the total area. He also makes suggestions as to planting, thinning. logging, improvements, 6 FOREST REGULATION etc. ‘he whole document, with maps, is submitted to the upper office, approved, copied, and one copy kept at the Forester’s office to serve as directions for the next 20 years’ work. Here then is a forest business, where lands, for the most part inferior for agriculture, have been made into an enterprise paying a net rental of $9.00 per acre and more, with an income value, at 3%, therefore, of over $300 per acre. ‘Ihe systematic work, the faithful following of a well conceived plan, has given to this forest certain advantages which the best of Silviculture alone, could not have accomplished. It has established order, it has produced a regularity in the age of the different stands (in the age classes) which alone assures a regular yearly cut of timber. This same regularity also assures that the timber which is cut here is of the proper age, i. e., of the size desired. By a systematic, well planned cutting and prompt replanting, the stands of different age are properly mixed or distributed in the forest, and thus accidents pre- vented and the dangers reduced. Through the division into small lots and into small independent woods (Cutting Series) Silviculture is given a chance to get at a stand in any time and way required, without starting trouble which might spread over hundreds of acres. Having good Silviculture and the regularity of age classes brought about through systematic cutting, the growth on this forest both in volume and quality is about as large as Site and Species permit, since there are no old, overripe, and defective stands which would make little or no growth. Moreover, this same regularity assures this growth, and a regular yearly income on the smallest amount of timber capital upon which, under these conditions, this growth and income can be made. Regulation, together with good Silviculture, has made here a splendid property, with a large income and has made it as safe an investment as a forest property can well become. A well planned and well built system of roads have made it possible to utilize every- thing to good advantage and easily doubled the stumpage value of every tree in the forest. Without this, the material cut in thinnings would be mostly valueless, and even the old stands would have to be cut in much larger bodies to pay in logging. But. while the present good conditions of this forest are due, in a large measure, to Regulation or the orderly business-like treat- ment of this property, it must not be supposed that it was due to CERMAN FOREST 7: any particular Formula or Theory of Regulating the Cut, it was not even largely due to the Working Plan of 1860 and the revisions since, for this forest was in good condition, as all the old stands amply prove, as much as 80 and Ioo years ago, and there had been good business here long before most of the formule and theories of our books had been published. It was the orderly work of capable men, faithfully persisted in, which built up this forest. On the other hand it is also true that it was Cotta’s teaching of Regulation which gave to this forest (and hundreds of others) the proper division into Lots, and prepared the way for the necessary road system, and it was also Cotta’s teaching which established the method of Regulating the Cut now followed here, converting an unsettled practice into a well-based, and recognized policy. This, then, is the kind of forest business which the forester wishes to establish and develop in the U. S. and for which there is the best of opportunity and the greatest of need. Several hundred million acres of wild woods await proper development, and a nation which uses over half of all the lumber cut in the world, is dependent on this development for its future supplies of timber. 3. HISTORY. Forest Regulation, like Silviculture (and farming) is not new. To be sure, history tells but little about the arrangement of the work in the woods. But the excellent forests which were built up and of which at present some old stands date hack 200 years to testify to good Silviculture, at least; then also the supply of good timber continuing for centuries, as recorded in the history of cities like Zurich, Frankfort, Nuremberg, Vienna, etc., and the timber business of the Rhine and other rivers, and lastly the scattered fragments of direct written record, all these clearly show that an orderly procedure in starting, caring for and in harvesting the crop developed early. In 1359 the forest of the City of Ehrfurth was divided into seven parts, to be worked over in regular order. In 1422 the City Council of Zurich decided that the cut of the Sihlwald shall not exceed 20,000 pieces of timber per year, probably the oldest recorded volume regulation known. In 1630 a regular system of bookkeeping was started in this same forest and in 1696 the first 8 FOREST REGULATION regular written Working Plan was made for this property. The commission created for this purpose decided on a Volume to cut each year and this cut was continued up to 1835, and has not been modified very much to the present time. Since a great deal of the forest about town and village were coppice woods where a piece is cut clear each vear and thus an Area Regulation grows of itself, the regulation by setting a definite volume was probably the excep- tion, and no doubt Schwappach is right when he states that Area Regulation was the rule from about the year 1300 to 1800. The Regulation or the preparation and development of Work- ing Plans for the forest was a matter of slow growth, in keeping with the slow progress in all directions. Before railroads came into general use, i. e., before about 1840, even the building of highways was restricted to a few trunk lines, and most of the country roads were almost useless for heavy hauling, and thus land-transportation of timber limited to very short haul with little efficiency. As a result of these conditions, the woods about the villages and towns were largely overcut, and those a few miles away were hardly used at all, unless the timber was Spruce or Pine and could be driven on the stream. The income from forests was very small, in many places the grazing and game being worth more than the timber. The net income in the State Forests of Wirttemberg well illustrates what these conditions were even after the year 1800: NET INCOME PER YEAR. ACRE AND YEAR. 1820 to ’24 $0.55 1830 to 734 0.70 1840 to ’44 1.79 1850 to '54 1.05 1869 to "64 3.16 1870 to "74 3.62 while today the average net income is more than $6.00 per acre and year. With net incomes generally less than 25 cents per acre and year, the great body of the German forests was not in a condition for better methods, either in Silviculture or in Regulation or business. With the rapid progress of the past century, the increase in popula- THSTORIC SKETCH 9 tion, the development socially and industrially, with highway, railway and canal building, the price of wood advanced, and even the remote woods could be made valuable. It no longer paid to wait for natural reproduction in badly treated, half-wild woods. Clear Cut and planting became the rule: the old woods roads, often half slide, half road, were abolished, well planned and well located roads were built and every lot was made accessible to good wagon and sleigh haul. These developments cost vast sums of money, and for years the net income was low accordingly, but now they are largely finished, and the income is going up rapidly and steadily in the State Forests of every State of the German Empire. Modern Forest Regulation as taught in the text books of today is a development of the last 150 years. As early as 1740 Jacobi taught Area Regulation with reduced areas; Frederick the Great ordered the division of the Pine woods of Prussia into Fixed Yearly Cuts and about the same time Reckman taught Volume Regulation. In 1795 the elder Hartig published his work on Volume Regulation, and in 1819 introduced this method officially in the Prussian State Forests. In 1804 Cotta published his Area Allotment and laid the foundation to the Limited Allotment, or the ‘“Judeich Method” (of Schlich) which, with slight variations, is today the official Method of the State Forests of nearly all German States. Lut to Cotta the Working Plan was more than merely a Regulation of the Cut in Volume or Area; he insisted that a proper division of the forest into Lots and into independent parts (Cutting Series) and then also a proper road building, the faithful following of the Working Plan and a regular revision of this Plan to adapt it to the ever changing conditions of the forest. were of far more importance than the mere estimate or calculation of the volume of timber which might be taken yearly from a forest in a particular period. All through the past century numerous authors added to the literature of Regulation, and suggested various methods of Regulat- ing the Cut. Stress was usually laid on the explanation of the perfectly regulated forest or “normal forest’ as a model, and also on the numerous methods of Regulating the Cut, and this peculiar emphasis went so far that even at the present time there is a feeling abroad that the various theories and formulas which have been invented (for the most part not used) of Regulating the Cut of 10 FOREST REGULATION timber, are all there is of importance to the subject of Forest Regu- lation. In recent times there has been, even in the texthooks, a return to Cotta’s position. Judeich, really the strccessor as well as pupil of Cotta, follows the master; but the best exposition of the knowledge, appreciation and attitude of the well educated practice as well as that of the administrations of the German State Forests, is contained in Martin's Forest Regulation of 1910 where 50% more space is devoted to the directions concerning a proper division of the forest in plain and mountains, than is devoted to the methods of Regulating the Cut, all put together. From the foregoing it is apparent that Forest Regulation is old. that good, well planned business existed in the forest as much as five centuries ago; at least in those forests where a regular profitable utilization was possible. (Zurich City Forest.) It also appears that Regulation shared in the modern development, but that the great factor in this progress lay in the development of market and trans- portation which gave to the forest the reason for doing and the funds to do with. Today there is hardly an acre of state forest in the German Empire, and not an acre of village or city forest which has not a regular, well conceived, carefully prepared and closely scrutinized Working Plan, which must be followed by the forester, and which is revised at regular set intervals. The same is true for all large private holdings and applies almost as much to France, Switzerland, Austria, the. Netherlands. and Scandinavia and a large part of Russia as it does to Germany. In the United States Forest Regulation, thanks to the progres- sive policies of the United States Forest Service, is well under way. Millions of acres of forest have been examined and the age, size, growth and behavior of most of our important species has been studied on many thousands of trees, and on thousands of stands of timber. Forest Regulation, next to Protection, forms the principal task on the great National Forests, where Working Plans are started and developed for an area of forest five times as large as that of all the forests of the German Empire, and are developing with real science and support and at a rate probably never equaled anywhere in the world. GERMAN CASE II 4. THE GERMAN CASE OF REGULATION OR PREPAR- ATION OF A WORKING PLAN. To understand the task of preparing a Working Plan in a German forest, and also to appreciate the textbooks on Regulation it is necessary to keep in mind the conditions under which the work is ordinarily performed. a) Practically all cases of Regulation in the State Forests (and these are chiefly considered in our books) are tasks of Revision. If a plan is due the following conditions hold:. The present plan is 20 years old. Twenty years ago every stand of timber was examined (except, of course those less than 20 years old). The age of the stand was even then known from a previous plan report; the condition was noted; if ripe or nearly so, or in bad condition and therefore in need of cutting, the timber was estimated ; the care which the stand had received, i. e., whether properly thinned or not, was noted. In short, the stand was described, and this description is part of the plan which the Forester has in his office. This same plan indicates the stands which were cut during the last 20 years and the plan of planting tells what was to be put on the land; and the Forester’s books show what was actually cut and planted, and when each job was finished. The Plan report and maps indicate and enumerate the Lots into which the forest is divided, and the independent woods (Cutting Series) which have been established and also the order of cutting the timber and the direction in which this cut should progress on each of these cutting series. The Plan of thinning iridicates when the stands were to he thinned, and the book records show exactly when each stand received attention. The Plan report also enumerates and describes the roads, the boundaries, and the division lines and their condition; also the houses and other improvements on this property and in what condi- tion they were 20 years ago, the improvements which were to be made; the book records show how much of this was actually done or left undone. The Book of the office states how much timber was cut, its value and the cost of logging. It also tells of all important accidents, bad seasons, heavy storms, etc. 12 FOREST REGULATION The stands are practically all man-raised, most of them (over go% ) even age and mostly pure stands, easily accessible and easily and conveniently looked over or examined. The thinnings have taken out the crooked, defective, etc., and the stuff is therefore quite uniform and sound. Markets and means of transportation are long established, well known and hardly need consideration. ‘This, then, is the property to be examined, described, and reported, for which a new forest map is made, and a Working Plan prepared. ‘The Forester in charge of the task has all these data in his possession, he has a map guiding him from one lot to another: he knows beforehand what kind of timber he is to find on each lot. what its origin (planted or natural reproduction), its present age. its condition 20 years ago, whether it was cut and when. and what was planted on the land. All this is so radically different from the task of the young American Forester, who goes out into the wild and unknown forest. And yet all these conditions affected the men who have written the texthooks, and have, therefore, made these textbooks assume condi- tions, and demand record, map and plan such as it is utterly impossible to supply under wild woods conditions. In fact these impossible demands have often made Regulation seem “impractic- able” and even absurd, so that the young forester “lost heart’ and refused even to try to do the possible and feasible. It is evident, from the ahove, that Regulation becomes easier. simpler, and more accurate with each revision, and herein particularly lies the valuc of these repetitions. The work is usually not done by the Forester in charge of the particular woods" but, in all state forests, this task falls to a man from the office of Forest Regulation. This office tries to get around once every 20 years to all forests of the State, and it also makes an “Intermediate Revision”, a sort of special inspection every To years. The following tries to describe a case, following modern instructions. b) Premises: Plan to be made in 1914.

He is allowed such help as he may need. He has in his possession the present Working Plan, maps and the report of the Forester, furnishing all the information, as spoken of above. In most cases he has never beer on this forest before. d) Gathering the Information. ‘This mangoes over every stand in the forest, and describes the stand and its present conditions with the following distinctions: 1) Description of young and middle age, sound stands. ‘This is quite simple, he mercly needs to note: a) How fully is the land covered by timber, i. e., degree of stocking. i b) Health and thrift of stand. c) Care it has received; i. e., has it been properly thinned. d) Age is noted, though of course he knows this from the records. e) Suggestions as to what should be done. This part of the work goes fast; it is chiefly a matter of travel. for the quality of the work depends on how much of each stand he has actually seen, and in these dense forests, in young stands, the distance of vision is not great. 14 FOREST REGULATION 2) Ripe stands, i. e., those of the last age class, in Spruce, here 80-100 years old, he estimates by samples; in some cases he calipers and gets volume, quality and thus value by the Urich method ; in other cases he merely states degree of stocking and uses the Yield tables to determine the amount of timber on the lot. He also notes condition of stand, and makes suggestions as to its treatment, i. e., whether to hurry about cutting, etc. In many cases he examines the stand for its growth, using borings and Schneider’s formula. 3) The Description of Defective stands and stands where the growth is evidently poor, and also open stands, where wind, snow, etc., have opened and reduced the cover to 0.6 or below in density. Stands of this kind require much extra work, for they must not merely be seen but must be studied. He estimates the whole stand; determines density or degree of stocking; the age he has from his records; he tests the growth by borings, and finally he decides as to the best treatment. If the stand is very poor, and is making no growth of value, he suggests its removal during the next 10 years, with suitable re-planting. It is particularly this class of stands which taxes the man’s knowledge and draws on his experience. 4) The Description of the Selection-forest. Ilere things are not so simple even if the forest is in good condition. The work needs to be done more in detail and it also requires more care and judgment. Old and young is mixed on the same acre, the picture is one of endless variation and with every step, the composition, and age classes (here really size-classes) change in their relative pro- portions. Here each cut takes: Ripe Stuff, i. e., trees over certain sizes; (harvest). Inferior and defective stuff; (improvement cut). Thinnings of good material and the cut also should stimulate or assist reproduction. Whether this has been done and done well, whether there was left enough of timber per acre to secure good growth, whether the age classes are well represented, and other related points need to be judged by the man who examines and describes these stands. 5) The description is made in a Manual. or on loose sheets. each lot receiving its own sheet or double page with printed form, which reads about as follows: T5 GERMAN CASE ‘aday BUN}, -ynd a1ojoq sieak SI ysea] 3e ‘potiad jo pua : Jeau [yun pem faord ‘gq Rds Jayeaq jo yedsoid) o wl 9 9 goz zs es v £ JA | SIL +6 ov ce) ynq yyMo13 100g 9 yoa0gq ete yoaag saproe waa Shee I ze | ZY +g zy og € v-£ | AT | £9 +6 cz q -o1d 0} siedh OI 4X9u aonadg yma eq pimoys 4 [RJ PuUIM wor; Jasuep I mes[e e yO junos2e uo q 433) | Sz gs S esi S 9 ¢ ¢ A 0g req of -je yno aq ysnyy “e 6 ‘yyMoIs add ON. sonidg ‘spue}s 9soL yim oO y : sae ag | EO . ae ae : a ae ance a W pueys | Ios eae : : P end JOA or ‘mou | ‘J oa ‘O1/1 Sa ke ‘seo | sivad (a8eg pur} }cl mt ul 1210} : ub a4nyXxXtwu wsry) —-:sytewMay us Ot | paypoas P7944 | soaay| s}o]-qns 3a13ap ypoaeq oe ‘ealy | “fz 40°] “paqeuiysa ‘payeuinysa ‘saqualy 16 - ul ‘esas oh Mt Pra a Ayisuad| sonidg sh me yuading Ayyend) UNO, . cae oie ‘yshiq ATIaqyIeIq YUM ATIpwas 1aA09 syods uadg¢ SPN ‘ASI-O1 ‘N 0} adofg : Ayde1sodo 7, ‘slow pue daap pios {spurl Aep> pue weoy ‘A[paAeIc) 1945 ‘TT pue ] ‘ON YOIRIIS BuPOAA “GZ “ON 30°] ‘Ye ozi “SANWLG YOY NAAW NI LOT 10 NOMAOSIC ATANVS 16 FOREST REGULATION 6) Improvements; the boundary and division lines, the roads and buildings, nursery, etc., are inspected and their condition briefly noted and suggestions added. In rare cases, the division is not found satisfactory, and occasionally parts of the Loundary or division lines are re-run fo- verification or correction. Where radical changes in the division are indicated, the matter is first put on map with recommendations and if approved, a change is made, new lines run and blazed, or, in young stuff, at once cleared and opened. 7) Outside Conditions, of market, labor, transportation are not studied, ordinarily, by this man, but the office depends for this kind of information on the local forester and his report. e) Compilation of the Information. The forester in charge of this Working Plan work now has: 1) Detail Description of every stand on the property, say about 250 sheets. : 2) Notes regarding improvements, roads. buildings, nursery. etc., and possibly outside affairs affecting utilization. 3) Information from former reports and plans. This informa- tion is compiled into a brief general report, and then worked into a Working Plan. These two, Report and Plan are not kept. clearly separated as a rule. 1) General Report. Here are repeated numerous items, long known, and stated, or repeated in each plan for sake of complete- ness and for use of persons at a distance, therefore not familiar with this particular forest and its surroundings. Items here are: name of forest or revier: area total; area forest land, waste land, area wooded, and hare; topography, climate, at least special points of interest in growing timber: character of land, soil, drainage: market: transportation; labor: difficulties in pro- tection, etc. Then also improvements: divisions of the forests: this also heing shown on maps. Special attention is paid to Rotation and to the Species. Each plan carefully considers whether the Species grown here are the hest suited to the land and to market, etc., and also whether any particular Lot should or should not continue to be stocked with the timber now on the ground, and whether the age of 100 years is the right age at which to cut the Spruce, ete. : GERMAN CASE 17 Finally there is added a compilation of income and expenses taken from the records of the office, and usually an enumeration of the men or staff regularly employed. Of the maps the one representing the stands, their species and age (by colors) is renewed and brought up-to-date. Then there is worked out for each Work- ing Section (except the Selection forest) : 2) Table of Age Classes; which takes on about the following form. Workinc Section I, Spruce, Roration 100 YEARS. Age Age Age Age Age Age | Class Axes Lot Class | Class | Class | Class | Class | VI & & and | Area | I II Ter |} av V_ | older — : Sub- ] acres. 1-20 | 21-40 | 41-60 | 61-80 | 81-100] over ee lot. years | years | years | years | years 100 rahies acres. | acres. | acres. | acres. | acres, | years f acres, 1.2 49 — 40 —_— | — — — | — 1.b 35 cenit (il coacseal (Ncamacx 35 — | S 2 60 — | — —_— | — 69 — — 8.4 20 —. — —_—_ | — —- 20 —- 3.b 39 —e — — — —. — 30 etc. etc. Total is: 1709 1109 1309 goo 800 200 — Should be: 1200 1200 1200 1209 1200 — — The addition of these tables presents the Age Class conditions, and tells the forester at a glance how much land is stocked with Spruce of the different ages and how far the age classes are irregu- lar. Thus in the above case, age class I has too much by about 500 acres, etc. 3) Table of Sites, i. e., a table showing the quality of land on different parts of the property. This table takes about the same form as the table of age classes, the Sites, usually I-V, taking the place of age classes, and compiled directly from the detail descrip- tion of the Lots. This important table tells how much good, medium and poor forest land there is on the property, the criterion here being the height of trees of given age, and still more the volume of timber -on a fully stocked acre of a certain age. 4) Stand Table. This is an incomplete table; it brings to- gether only the stands which are now ripe, and also all stands which 18 FOREST REGULATION are in poor condition and should be cut during the next 20 years. The information is first gathered from the table of Age Classes (see above) and then corrected by the original field descriptions. At this point the good sense and training of the forester are very much needed. ‘The aim here in the Spruce Section is to cut only about 1200 acres in the next 20 years, to secure, gradually, a greater regularity in Age Classes, this being the normal area to cut in this Working Section, i. e., 6000/100 X 20== 1200. Whether or not-it is good policy here to cut the 1200 acres during the next 20 years is quite an important question and needs a careful consideration of the whole situation. Since both the 4th and the 5th Age Class are deficient and the 3rd contains only 100 acres more than it should, it would seem better to save a little during the first 20, and probably even during the second 20 years period. After deciding on the total area, it is necessary to decide what stands to take and what stands to leave for another period. In cases where a con- siderable number of defective, injured stands make up a large portion of the older stands this choice is anything but simple, and many a good forester has chafed for years because at the last Revision the plan required him to hold a lot of stuff which is diseased and dying in spite of all the care possible. The stand table commonly takes on about the following form: Workino Section I, Spruce, Rotation 100 YEars. StTanps SELECTED FOR YEARS 1914-1933. (To nf REVISED IN 1924.)

Etc., etc., GERMAN CASE 19 Where the Age Classes and conditions generally are very irregu- lar. as they sometimes are even in well managed forests, after insect- calamities, etc., the stand table takes on a different form. It is more comprehensive, takes in all the stands of the forest, or at least all over 40 years, in the case here considered. The following sample will illustrate this: Arta ALLOTMENT FoR Workinc Section No, 1. Spruce, ROTATION 109 YEARS.

This table resembles the ‘l'able of Age Classes, but is amply annotated with statements concerning the character of each stand and directions for its treatment. It thus presents the conditions of area and requirements of all the stands of the forest in a convenient form, and facilitates the selection of stands for the next 20 years, by indicating what may be expected here not only at the end of the next 20 years but for the next 6o and more years, in fact, in the above table for the entire 100 years to come. There is no thought of making this allotment binding; it is merely to serve the purpose above stated, and this table is re-constructed every 20 years in keeping with the conditions which will then be found. When the stands for the next 20 years are finally selected, they are worked over once more and a Detail Plan of Cutting is prepared, which tabulates the stands to be taken during the first 10 years. The following illustrates this table: 20 FOREST REGULATION 5) Detail Cutting Plan for the years 1914-1923. Workinc Section IJ, Beecu, Rotation 120 YEARS.

Reproduce slowly, avoid damage from 28.e as 375 storm; exposed position. Etc., etc., etc. This is a most important table; it tells the forester exactly what to do, where to cut, etc. A table. practically like the foregoing is prepared for the Plan of Thinning to be done during the next 10 years. 6) The Selection Forest receives its own Plan. This is usually a simple area table which directs that each year about 1/15 part of the area is cut over. Since the timber is not all cut at any one time there is need for setting some volume as the amount to take per acre. Since the “Return” here is every 15 years, the cut should take about 15 years growth each time going over the forest. If an acre is estimated to produce 75 cu. ft. per year, then the cut, each time, should take about 15 X 75==1025 cu. ft. per acre of forest actually cut over. This plan appears ahout ag follows: Working Section No. III, Selection, Rotation about 150 y.; Diam. of ripe Beech—16” ; Spruce—t4” ; Balsam—-16”. Average Growth per acre estimated at 75 cu. ft. per acre. Cut, therefore, takes about tooo cu. ft. per acre, at each Return. Diameter limit merely a criterion in thrifty good timber, i. e no good Reech cut under 16” except in thinning. GERMAN CASE 21 Cutting Plan for 1914-1923.

The plan for the nursery is added here, or a separate one is made. 8) Plan for Roads. ‘This also is a forecast for the next Io years (not the whole 20 vears of the life of the Working Plan) and usually takes in roads, trails (footpaths) and also chutes, slides, logging rail- ways, so that there is hardly a limit here, and the plan might as well be called one of improvements. ‘The form is usually very simple. so that it does not replace detail map and specifications in cases like railroad, chute, etc., but merely keeps the tasks clearly before forester and inspector. 22 FOREST REGULATION PLAN or Roaps AND OTHER IMPROVEMENTS FOR IQ14-1923. ost.

Then also maps; land map; topographic detail map; stand map, this latter representing in colors the stands on different lots and indicating species and age class. Commonly also a map of forest division, simply giving lot, sublots, cutting series and working sections. These maps are all merely corrected copies of the old set of maps. Different States have different ways of presenta- tion, and differ in the amount of details added to these Plans. It 1s.interesting to note that Saxony, and Wiirttemberg, the two most advanced States as regards forestry, have probably the simplest forms, and the smallest amount of details. 10) This body of documents is fastened together and forms the complete Working Plan. It is really made up of four more or less distinct parts: a) Detail Report or Descriptions, kept separate. b) General Report c) General Plans fastened together. d) Detail Plans GERMAN CASE 23 This document is submitted to the local Forester, where it receives the most critical examination. It then goes to the office of Regula- tion, and, if no controversies come up, receives the approval of the highest official. It is copied, and one copy goes to the local Forester who then works according to this plan for the next 20 years. At the end of 10 years there is a special inspection and, at least in some states (Bavaria) there is a new allotment of Stands, so as to give the forester a considerable number of stands to select from each vear. At this revision new detail plans are made. 11) The above outline suffices to show that the task of regula- tion as described in the textbook is feasible and perfectly practical ; that each revision merely improves the plan: that this new plan does particularly two things: a) It keeps the office (owner) informed of the exact condition of every stand on the property. b) It adapts the work in the forest to these conditions. The above also shows, why the German textbook does not go into the matter of survey, timber estimating and description such as is needed in our wild woods, and why therefore these textbooks seem so far removed from the actual task of the American Forester. PART II. THE REPORT ON THE PROPERTY. The preparation of a Forest Working Plan, as seen from the above, involves two quite distinct tasks: The gathering of the Information and compiling this into a Report on the Property. The making of the Plans for the Property. In all cases the field work of gathering the necessary informa- tion is by far the greater task. In the United States with our wild woods conditions the plan itself must often be left tentative, and seems so crude that the whole Working Plan really appears as nothing more than a survey and description of the property or a report on the property, though, of course, this is not true and is merely a case of losing sight of the real object for which the infor- mation was collected. Better to appreciate the conditions in the United States which demand or lead to a Working Plan, and under which such a Plan is worked out, and also to see more clearly what such a Working Plan can and should contain and what it should accomplish, it may be well briefly to review the circumstances and the process of a typical American case. A tract of private property, rather than a State or National forest is chosen, because these latter forms of ownership involve a large organization where the making of a Working Plan, now, is merely one more task in the great routine of work. A. THE AMERICAN CASE. 1) The assumption here is that a man in New York owns forest lands in Northern Michigan ; that he is not, at present, in the business of lumbering, and that he wishes to know more about the property. with the possibility of converting this property into a regular forest business. AMERICAN CASE 25 When buying this land it was cruised in the ordinary way and he has, therefore, about the following information: Area: 30,000 acres, all surveyed land (United States Survey) practically solid; in two Townships. Forest and Lands: about 25% originally pine on sandy lands, now cut and the land burned over. About 60% uncut hardwood and Hemlock on loam and clay lands with about 6 M. ft. merchant- able timber. About 15% of ‘Tamarack and Cedar Swamps, esti- mated to average 3 M. ft. His local representative has informed him that the saw fly is destroying the Tamarack, and that the fires of 1908 injured part of the hardwood forest; exact figures lacking. His estimates are by 4o-acre tracts and usually include a few notes concerning land and topography. The property cost him $450,000 and is assessed at this figure. His taxes are $15 on every $1000 worth of property or $6750 total ; his expenses for representa- tive, a Jocal lawyer, for occasional cruising to watch for trespass, costs another $2500 per vear. 2) The owner sends for a Forester; and after a brief interview he decides that he will pay the Forester $600 for a preliminary report on the tract (i. e., two cents per acre). The owner prefers a brief preliminary report because he is not certain what he should do with the property, and it is the chief function, therefore, of this prelim- inary report to state truthfully and conservatively those facts which the owner should have in order to judge, intelligently, as to the best policy to pursue. The Forester now goes to the locality, usually with letters and maps and a list of lands making up the property, commonly as list and also in form of township plats. His work will arrange itself as follows: a) Visit to local representative. Here he gets names of men who can be helpful, chiefly local cruisers, persons to see and to stop with while going over the tract, names of county and town officials, names of timber people, loggers, sawmill men and buyers. Jn many cases he may need county map and town plats, usually obtainable at the courthouse. b) Examination of the tract. For the purpose in hand, this is a hastv survey, covering the 30,000 acres in about three weeks. 26 FOREST REGULATION He needs a local man familiar with the tract, and able to take him at least to a fair number of Section corners without special delay. Aside from a numher of samples, to steady his judgment, it is not a detail estimate or cruise, but an orderly covering of the land to ascertain: Character of land, topography and soil. Character .of forest; its present condition on every section; proportion of swamp, hardwoods and pine lands. In such a cruise it is enough to know, at any one time, that it is good hardwood forest, and it is not necessary to stop and estimate the amount of timber by species, etc. It is well to verify a few estimates of the cruise made for the owner at time of purchase. Matters of reproduction, growth, and also cases of burns are noted, but not studied in detail. . c) Study of General Conditions. This is a matter of canvass as well as visit. Here the Forester learns about: Roads and streams which may be useful to the enterprise; distances to railway, to sawmill. Market for the different kinds of stuff now upon the land; chance to sell on stump, in log delivered, value of lumber, poles, ties, etc. Chances to get labor, wages, etc., to get logging done by con- tract, and usual prices; to get stuff manufactured. Safety of property from fire and trespass and possibilities to make it more safe. Agricultural and other development of the district. Notes on climate, days of sleigh haul, usual depth of snow, matters of frost (agriculture) ; regular dry spells, and also recur- rence of dry seasons. A great deal of valuable matter is gathered incidentally. From the local representative and still more from local people the attitude of the people towards such a large property should be ascertained. This outside study should take alout 1o days. d) Compilation of this information into a Report. This report must be very brief, and even then it should have the most essential points separated and categorically stated on one page. AMERICAN CASE 27 The Report should cover at least the following points: Area and Location of property with special reference to Rail- way, town, mill, settlement and also with regard to distant, large market. Transportation: for timber material, present rates to important points. Business: development of district, lumbering, agriculture, here especially a reasonable outlook. Land: its topography, soil, drainage; value for farming; climate and crops. Timber: merchantable timber. If old cruise appears satisfac- tory compilation from this; condition of timber, present stumpage value and outlook ; all on a brief, three or four line table. Growth: If no net growth here, this should be stated. Price growth, i. e., growth due to increase in market price for each kind, for recent years. Forest: Age conditions, Reproduction, young and middle age (by sizes) ; defective stuff. Improvements on the property: roads, etc. Exploitation: Chances for labor, contract work in logging and milling ; usual methods. Climate and exploitation, snow haul, depth of snow. Protection: Fire and trespass, also loss from sawfly, in this case and other troubles; dry spells, dry years, large fires in district. Property and Forestry: Location, size, form, whether land and climate are suited to forestry ; advantages of market, and transporta- tion, probable future of district. Possible Plan: Necessity to decide definitely on holding the land; general plan to cut over, protect, improve, possible income and expense ; development if a plan is followed ; comparison to European properties of same character of soil and climate. A State Map and County Map should accompany this report to show general location, especially lines of transportation and market. A copy of the original town plats showing streams, swamps, etc, as per old survey. On this may well be indicated cut-over lands, and swamps Ly colored crayon and also such roads as now exist. 28 : FOREST REGULATION 3) At a second interview of owner and forester, the important points of the above Report are discussed. If report and conditions prove satisfactory the owner decides to have a regular Working Plan prepared at an expense of not to exceed 25 cents per acre, or $7500 total. The Forester now repeats his work, but does everything in detail, so that instead of merely sampling the tract along the section lines, he goes over every 4o0-acre tract at least twice, and, where needed, he makes side-trips, so that he sees practically every acre of land on the property. This detail study also locates every corner, and re-establishes all lines. In addition, the Forester makes a number of detail studies of growth, of the few important species. With regard to outside condition, he not only learns about the chances of getting logging, etc., done and the general price, but he gets the names of men ready to contract and the prices at which they offer to work. a. The Survey and Inventory by 4o-acre lots is made on regular printed forms, one sheet to each 40; and states: The kinds or species of timber, and the proportion of these on the 4o-acre tract. Age or sizes, represented. Amount of merchantable timber ; above 12 or 14 inches diameter breast high; usually by kinds. Density of timber ; or how fully is the land covered. Condition of timber; shape. size, defect, of both merchantable and non-merchantable stuff. Young stuff; reproduction, sapling and pole stuff. Land; topography, surface, soil, drainage. Accidental Conditions; burns, windfall, bare land. All this information must be called for in such form that it can readily be taken down in the field, easily seen on the sheet, easily taken off the sheet for compilation. On this property there would be about 750 separate sheets or descriptions and it would be useless for anyone to try to learn about this property without compiling this mass into one or more general statements and tables, and thus preparing a General Report. For AMERICAN CASE 29 this reason, the very form on which the field-data are noted, needs careful consideration. b. When finished, the Forester has: J. 750 separate sheets of field notes. 2. About so Maps, detail, made in the field. 3. Many pages of figures collected to learn ahout the growth of timber, both as to the individual tree and the stand of trees. 4. Also pages of figures for Volume tables. 5. Many pages of notes concerning outside affairs. The field notes should be copied; the growth figures and volume tables compiled and made into tables and diagrams. Then this mass of Detail information should be compiled into a General Report. This General Report should be brief, it should resemble the first or former report, and it may not have a great deal of additional! material. But it differs from the first report in the most essential point: It is based on actual detail knowledge. c. Based upon this Report, detail and general, the forester pre- pares a Working Plan. ‘This Plan preferably falls under two heads, the General Plan which outlines what is to be done with the prop- erty, usually for vears ahead ; and Detailed Plans which tell what is to be done during the coming year; exactly where to cut, to build roads, etc. The General Plan can and should always cover :” t. What is to be the policy of the owner: Hold the lands, gradually convert it into forest business, but not require more than X% of stumpage receipts per year to be put back on the prop- erty, etc. 2. Timber Cutting: Whether to hold, or begin at once; sell stumpage or log per contract; about how much to cut over per year, etc. 3. Silviculture: If cut over by logging the large stuff only, then to what diameter to cut the different kinds, how closely to cut it over. i. e., how much should always be left on the land; how should the stuff be marked where there is no voung growth, and how, on tracts with much young growth, etc. Here also: should, if necessary, a little money be spent to get rid of defective stuff and 30 FOREST REGULATION to get rid of tops. Also, should a replanting be done, and if so, with what kinds and should the stock be raised in a nursery on the property. 4. The best ways of protecting the property; what authority should the forester have to hire extra help in danger season ; method of paying help; improvements, especially telephone, cabins to shelter the men; fire lines on the sand lands, etc. 5. What help is needed. how many regular men should be em- ployed, what their salary and duties. 6. How much money should be allowed for the first five years, regardless of incomes from timber, and what should be the maxi- -mum to be allowed. 7. Some estimates of income and expenses. 8. What records or hooks should be kept and what reports made, and who should inspect the property to see that the plans are actually carried out. d. Detail Plans. These cover especially : 1. Plan of Cutting the Timber; the areas to take the coming year, perhaps also the following: How it is to he logged, by whom and under what conditions of scaling, delivery, price, etc. Here also bark peeling, cordwood cutting, etc. 2. Silviculture; particularly the way of marking the timber, giving as detailed directions as possible. Then, also, brush disposal, removal of tops and defective stuff (this part of Cutting Plan). Plan for nursery and reforestation for the next few vears, stating definitely how large a nursery, what kinds to raise, what forties to plant up, etc. 3. Plan of protection, to outline in all necessary detail exactly what to do, whom to call for help. how to report, etc. 4. Plan of Improvements, i. e., exactly what houses, barns, camps, roads, telephone lines to build the first year, and about what kinds and at what cost. 5. Plan of Organization and Funds; i. e., name and number of men to employ, how much extra help, when, at what pay; how much money to devote to each line of work. To these Reports and Plans are added copies of all maps, here particularly three kinds: AMERICAN CASE 31 1.

Third Conference; the Working Plan is now submitted. By rights, the owner should have the work inspected, sampled and verified. If found satisfactory, it is received and paid for. This now ends the task, and the owner is free to use these documents as he sees fit. If he does wish to go into forestry, how- ever, he will find right at the outset, that a good forest Working Plan is nearly useless in the hands of an untrained man. Such a man can use the maps and the estimates and can have the timber cut and the forest cut over in the old, usually destructive way, but to use a Working Plan and build ‘up a forest business requires a forester. But even if the owner does not go into forestry, he will find, in most cases, that the expenditure (in our case $8100 for both reports) is well warranted on a property worth $450,000, just to know what the property really is, a thing which no ordinary cruiser report ever enables him to do. The cruiser report tells of logs and land (not always the latter) ancl leaves the forest, or the real prop- erty undetermined. B. THE FIELD WORK. The gathering of the Information necessary as basis of a Work- ing Plan and here summed up as the Field Work, usually involves three quite distinct parts: a) The Examination of the property, land timber and im- provements. b) Special Studies, mostly studies of Growth and Behavior of the most important kinds of timber on the property. c) Study of Outside Conditions, such as Market, Means of transportation, Chance for labor, Matters of taxation, etc. 32 FOREST REGULATION I. EXAMINATION OF THE PROPERTY. In the United States the examination of larger forest properties usually starts with rather scant information. Even where the land has been honestly subdivided, the maps are inadequate, the informa- tion such as the course of streams, etc., is restricted to points on the section lines and all information with regard to the interior is estimated, often merely assumption. ‘Topography, soil, stand of timber are practically unknown. In unsurveyed or only partly sur- veyed districts these difficulties are materially increased. And yet it may be desirable, even necessary to begin some kind of definite administration at once. Whether this leads to real forestry or merely to exploitation does not affect the case materially; at least a reasonable amount of information must be gathered, to enable the owner to come to some decision, and to make it possible to do business. In such cases it is not feasible, or even desirable, to wait for a detailed examination. For even the satisfactory planning of this detailed examination itself requires considerable information with regard to survey, topography and general character of the forest. For these reasons the examination of large forest properties in the United States generally involves two distinct steps, the Preliminary Survey, and the Detail Survey, though the line between these two is not clearly defined. 1. The Preliminary Survey. A kind of exploration work, justifies itself by gathering rapidly and cheaply, enough information to decide on a policy and future treatment of the property, or to enable the beginning of a Forest Administration. Thus the preliminary surveys of some of the National Forests, made by the United States Geological Survey covered several hundred thousand acres of unsurveyed country in a single summer. It seemed sufficient to learn the general topography, the streams and their valleys, the amount or proportion of forest, brush, burns, and waste lands in each valley; the soil and drainage, altitude, and changes of woods with this; the accessibility, and a few points regarding the use thus far made of these areas. PRELIMINARY SURVEY 33 In surveyed districts, these preliminary surveys usually sampled every section. In other cases such preliminary surveys establish systems of base lines or “control lines” from which caliper crews work out in both directions and cover the country in a regular order, and actually measure the timber on a certain per cent of the total property, and map and describe the soil topography, forest types, etc. Generally these preliminary surveys cost less than 3 cents per acre including office work of compilation and map work; they are necessary and useful. They merely sample by covering usually less than 5 per cent of the area; they do not leave a permanent survey or subdivision on the ground; they are not easily controlled or checked ; any verification requires a repetition of a large part of the work, and even then it is usually impossible to decide the merit of the case, for the inspection rarely follows the same line followed by the crew in the first place. Leaving no permanent survey marks, a later repeti- tion, verification or correction is impossible, unless the matter of land survey is specially attended to. Nevertheless the results are useful, and often surprisingly accurate. ‘The maps and descriptions alone justify the effort. Where the strip method and caliper crew are employed, the results are accurate for the samples actually measured, but thev are inference for the rest. In this way the estimate of timber, for instance, may he fairly good as an average for a large area (township, stream—-valley) but may not apply at all to a particular forty-acre tract. But in actual operations, log- ging, etc., it is usually desirable to know just what the forest is on a given forty and even the lumbermen have found it necessary, therefore, to amplify the information by a detailed examination, an estimate by forties. With these limitations, the Preliminary Survey is useful; it may quite suffice for many years in cases of remote properties with little or no market ;it is quite sufficient for protective forests, ‘‘timber- line” country, etc. On properties or parts of properties with good forest, with market for timber, and consequent development, the work of utilization with its improvements, of protection and silvi- culture, soon calls for more accurate and more detailed information. And especially do these lines of work demand that any information apply to a definite location, to an area clearly marked on the ground so that it can be found without repeating surveys, and to apply to 34 FOREST REGULATION an area small enough so that any work can be inspected, any results be verified, and any task repeated. Dut this calls for a Detail examination based on a definite subdivision of the land. 2. Detail Survey, or Examination of Property. Since the information in this case is desired by definite areas the task divides itself naturally into: Division of the land into suitable tracts. Orderly covering of these tracts in making the estimates, de- scriptions and maps. a. Land Division. In Jevel country and where the land is subdivided by United States Survey, the smallest actual division is a Section of 640 acres, and the lines and corners clearly marked on the ground, the descrip- tion and estimate may be started.at once without further subdivision. But even in this case, (which is rather the exception) it is desirable that the information be gathered by smaller areas, usually by forties or by 8o-acre tracts. This latter especially commends itself. Where the survey is old, badly done, monuments and marks largely destroyed, it is a waste of time, in most cases, to have the crew which describes the property, hunt up and re-establish the land survey, and it makes for efficiency and accuracy to make a separate task of this work. In this case, especially, it adds but little to the total expense per acre to have the Section subdivided into eight lots, by running the middle line E. & W., and marking on all F. & W. lines the 1%, as well as the 14 posts. In level and rolling country not covered by United States Survey, the United States method should have preference. In hill and mountain countries, or parts of such where the rectilinear survey is unsatisfactory, or where no survey exists, the subdivision should adapt itself to topo- graphy. Ilere the ridges, primary and secondary, together with the streams, normally form the permanent bases. ‘I‘he lots are no longer of regular form and size. The danger here is two-fold: To make the lots or tracts too large. and To make the lines on all ridges too crooked : both should be and can he avoided. FOREST DIVISION 35 , rage siz lots 170 acres.

The same tract as shown in Plate 2, The Division is adapted to the tepography and is largely made up of well planned roads. From Martin, “Forsteinrichtung.” > 38 YOREST REGULATION It is feasible even in high mountain districts to stay below 200 acres in the average size of the lot. For convenience the lots of one stream valley, or part of one watershed may be combined into a Block, and the lots of each block have their own series of numbers, and the Dlock is thus made to correspond to the Section in ordinary Survey. See Plate I. The lines of division normally follow the ridges or use the streams and where the distance from stream to top of ridge is too great lines parallel to the valley are established. Since roads and trails, normally use ridges and valley, or con- nect these two by oblique lines to suit grade and topography, these roads and trails are used, later on, in perfecting this land division. But even where such a road system is well developed, as in scme of the recent European work, the roads rarely make over 40% of all division lines in hill and mountain country, and it is probably a mistake to allow this use in land division to influence unduly the planning of a road system. See plates II and II. Of late, efforts have been made to base a detail description and estimate of timber on a partial and more or less temporary subdi- vision. (See Diagram fig. 1.) A set of base lines or “controls”, tied into a regular United States land survey, are established by use of solar transit and stadia, or chain measurements. From the prin- cipal one of such a series, a number of secondary base lines are run out on the ridges between streams. On all contro! lines stations are established at regular intervals, and number of station, and altitude marked on monuments, and recorded on map or in book. In this way the area is practically subdivided into tracts of several hundred, to several thousand acres in size. The description and estimate-work then starts at the stations set on the control or base lines, and tries to secure the information, usually by forties. If the control lines and their stations are made permanent and maintained in usable conditiun, this work may be regarded as a partial, permanent land survey and will well justify the expense. If the entire system of lines is temporary and allowed to disappear, the work serves only the purpose of a single survey and is certainly wasteful. In either case the description works on areas and reports on areas not actually marked on the ground, and thus has the short- FOREST DIVISION 39 comings of the preliminary survey, as stated akove. Since the mapping and description work is done in detail, this method is a combination of extensive and intensive work, with doubtful justi- fication.* Ficurr 1.

Dotted lines m, n, and o are lines of travel of the crew estimating and describing the timber. At I is a Section Corner, here used to “tie in.” b. Use and Value of Subdivision in Forestry. The value of a good permanent subdivision on the ground not only in Survey or examination of the property, but also in Utiliza- tion, Protection, Silviculture and even in Improvements, but most of all in proper Administration and Bookkeeping, is very great. It was fully appreciated by Cotta a hundred vears ago, and Martin * These base- or control-lines may be established by a crew of four men; transitman, recorder, rodman, and axman (changes in this to suit timber, etc.). This crew in fair country can do two miles per day at an expense of about $10.00 per mile. Stations usually every ten chains, with number and altitude. This crew maps along line; measurement by stadia. 40 FOREST REGULATION today emphasizes its value when he says: “The division of a forest into suitable lots (‘Wirtschafts figuren’) must be considered as one of the most important tasks of the field work.” (Page IV, For- steinrichtung. ) The necessity of such a subdivision and of having all informa- tion by definite, small tracts is fully appreciated today by the lumberman who demands information by “forties”, in spite of the fact that his interest in the particular area or forest ceases with the cutting of the merchantable timber. The forty as a unit of land division, of course, came into the timber business through the practice of the United States Land Office which has long used the forty as a unit of land area and land disposal. Intensive forestry has found it advantageous to subdivide to areas even below 40 acres, and few European foresters would recommend lots larger than 160 acres even on poor sites, and in rough country. The form of the lot (or compartment) should be as simple as possible; in level country the rectilinear form, twice as long as wide, with long axis perpendicular-to the direction of the prevailing wind, is quite generally employed. In mountains the form becomes irregular, but too great irregularity lessens the value of the division and usually adds to cost of division and still more, its maintenance. The Division, the Lot (compartment) is a land division, it is permanent ; it does not change with operations of Silviculture. etc. ; it is independent of the stand of timber on the land, or its condition of type, age, etc. Usually it is recommended to include in one Lot only one type of forest, only one kind of land, etc., but this is not always practical. Thus in the Great Lakes Pinery it is a common thing to find on one 8o-acre tract conditions as per diagram, figure 2. In this case, three distinct kinds of land, leading to three dis- tinct kinds of woods occur on the 80-acre lot. To separate these three types along the crooked lines of the border of the swamp. would not help things, but rather complicate. Were the lot as land division includes three types, three sites, and the forester in his description and in future treatment separates these three as Sub-lots. . Sub-lot is a stand-division within the Lot. In the above case the three Sub-Lots are permanent. but this is not alwavs the case. LOT AND SUB-LOT 41 Thus in an 8o-acre lot of pine, all 50 years old, a storm or fire may destroy the middle portion and necessitate its removal. This area is at once replanted, and the 80-acre lot now has a 50-year old stand in the North, and another 50-year old stand in the South end, with a young plantation between these. In this case the forester would Hardwoods Ficurr 2. Eighty Acre lot with types of land and woods, Pine Hardwood, and Swamps, leading to permanent Sub-lots or Stand-divisions. make an effort to get rid of this condition of three Sub-Lots, by regulating the cut, and the Sub-Lots would disappear at the latest during second Rotation. The Lot (or Compartment) does three things: It limits every stand of timber, etc., on the property to a piece of land small enough for proper location, small enough to enable its being found without delav and extra expense. 42 FOREST REGUI ATION It helps to make everything accessible; even a blazed line helps in going to a particular place. It creates, or helps to create small, independent woods, an arrangement necessary for good Silviculture in all forests of even age stands, and useful even in the Selection Forest. Subdivision of the forest is useful to all the important lines of work connected with forestry. A few points deserve special mention: 1. Land survey and Boundary. Here a good subdivision on the ground helps to maintain, verify and relocate parts of the boundary; it helps especially with regard to interior holdings; and it helps constantly in the use of the maps prepared in the land survey. 2. In Topographic Survey, it helps to make, check or verify and correct the survey; it locates all topographic features, and makes the topographic survey more useful. 3. The Timber estimate is more valuable if made by definite forty or lot. A lumberman who would gladly pay $2.00-$5.00 per forty for an estimate by forty, would not care to buy an estimate which would only give large averages, or refer to areas not marked and therefore of uncertain location. Subdivision helps to plan the work of estimating and describing the property ; it makes for a better estimate, since any one tract can be finished and can be treated in estimating according to its needs. Tt also enables proper control or supervision by checking, and it enables repetition without cost of re-location. In timber disposal the need for definite location is evident; a scale record must tell where the stuff was cut; an application, a report, a contract must state where the timber is located. 4. Plantation, Thinning, Improvement work generally require definite location; the work is better planned, easier directed, better reported and booked ; and only a detinite Jocation enables satisfactory inspection and supervision. 5. Protection is helped by subdivision; it makes the woods more accessible, enables the ranger to know his forest, stimulates interest, locates any damage and gives meaning to the report. In many localities a well blazed division line helps to prevent trespass ; and in all cases it facilitates prosecution. FOREST DIVISION 43 6. The preparation of Working Plans, their continuance and improvement; a proper inventory and set of records of a forest property all require a division of the property into parts or lots. And to be of value, these divisions must be small enough so that any stand of timber, plantation, improvement, etc., worthy of record is located and can be found without the expense of a special survey. c. Descriptions, Estimates and Maps.* This work involves an orderly going over the property, map- ping and describing land and forest and estimating the merchantable stuff on every lot. 1. Covering the Land. The lumberman frequently counts all merchantable trees on a forty by going several times through the forty. For his purpose this is a complete covering of the ground. Usually this is not done, the forest is sampled by going once or twice through each forty, exam- ining in detail a strip 4-8 rods wide, and assuming that this strip fairly represents the forest on this particular forty. In open timber, old stands of Southern Pine, Western Yellow Pine, etc., even this going twice through the forty permits seeing practically every acre of the stand, but does not usually count every merchantable or large tree, and gives no chance of study of smaller stuff except along the line of travel. In such open stands the estimate can readily cover four rods on each side of the line, or an eight-rod strip, which, by going twice through the forty means a cover of 20% of the area. Where a caliper crew is used, the strip is normally four rods total width, or two rods on the side, and thus forms 10% of the area. A 5% cover- ing, i. e., going once through the forty, may be considered the minimum in useful detail survey.7 In going twice through the forty in young timber, and also in brushy, denser stands, the forester does not see much beyond the four-rod strip and practically 90% of the stand remains unseen. * Most of this subject belongs to Surveying, Mensuration and Description, and only a few special points are mentioned here. t See: Margolin; Errors in Estimating Timber; Forestry Quarterly, 1914, p. 167; giving interesting comparison between 5%, 10% and 100% cover. 44 FOREST REGULATION Where the trees on the strip are calipered the estimate of mer- chantable timber is restricted to the strip. The same is quite generally true in ocular estimate, for the sampling requires orderly procedure. But the description does not tie itself to the strip but covers all the territory clearly seen from the line, a much larger per cent of area. In all wild woods survey the matter is complicated by special conditions. Thus clumps of old trees, containing large amounts of good timber may occur off the strip in the midst of a stand of sapling or pole stuff. If these clumps are not examined and esti- mated, the entire forty may be reported as being without any merchantable timber whereas in fact it may contain a great deal. Similarly cases of bare ground, burns, swamps, windfall, etc., require a departure from the regular program and a special survey to ascer- tain the extent of such a burn, etc., is necessary in good work. Just where the limit should be to which this may be carried in any given case, depends on the use which is to be made of the information, and the value of land and timber, or the property to be examined. Thus far the error has generally been made on the side of economy, and certainly a detail survey reporting a forty as having no mer- chantable stuff when in truth it has half a million feet, is sacrificing too much to system and instructions. From the foregoing it is apparent that the work should not be too mechanical, should adapt itself to the conditions, and in every case it should cover the ground sufficiently to avoid gross mistakes. Where stumpage exceeds $6.00 per M. ft.; where the timber runs 500 ft. and better per tree, and 10 M., or over, per acre, and especially where the estimate is to serve as basis of purchase of the property, it pays to count all trees and estimate or measure their diameter. Crew and Results. The old-time “cruiser” usually went alone, kept course, and distance and did the estimating. Later on a com- passman was added as helper, to keep course and distance. The caliper crew usually consists of four men; compassman, tallyman and two calipermen. Here the compassman keeps course and maps: the tallyman keeps tally and describes timber, the calipermen caliper the timber above certain diameter on the four-rod strip. Of late there is a return to the two men crew. with pacing and estimating CREW AND RESULTS 45 in place of chaining and calipering. As in the covering of the ground, it is doubtful if any one set form of crew should be used in all kinds of timber. The four men caliper crew, without doubt, is the most competent, accurate and reliable, especially where inex- perienced help must be employed. ‘These crews commonly do not finish any particular forty, Lut go one, two, or even more miles in one direction, i. e., through several sections and then offset and return. With ordinary compass and on rough ground this is a questionable practice; the crew is almost sure to get off the intended line, and it is not uncommon for a less experienced crew to miss the forty entirely. On easy ground and in uniform timber a crew covers about two miles of strip, and thus measures sixteen acres of strip, so. that, on a 10% cover, it finishes one section every four days, at an expense of about eight cents per acre. On rough ground and in brushy timber, the cost increases 50-100%. 2. The Information and its Record. The examination of a forty or lot involves usually two rather distinct parts: The estimate or measure and tally of the merchantable timber, and The description of site (soil, etc.) and forest growth or growing stock, this latter usually including notes with regard to the condition, quality, age, thrift, etc., of the merchantable material as well as the rest of the tree growth. Of these two, the description is of more importance in regular forestry, takes more preparation, knowledge and time. The estimate or tally is primarily a record of dimensions taken by species. In timber under 12” the record may well be arranged by diameter classes of one inch; in larger timber the record is sufficiently accu- rate if taken by 2”; and in timber over 20” d. b. h. 3” diameter classes are permissible. In the earlier efforts it was thought best to reduce the amount of information to be gathered, to as few simple points as possible, and thus gain in speed or economy. Accordingly the printed forms had but few columns; each column covered a variety of points with- out clearly asking one definite question, and a good deal was left to the column of “remarks”. The man in the field was in doubt, 46 FOREST REGULATION the matter seemed largely optional, much information was gathered for one forty and little for the next one, and much information was fragmentary. When these field sheets came to the office, only that part of the notes could be compiled which was gathered uniformly and consistently, such as the tally material, and the rest was not copied at all, or else “doctored” and inferred, and statements of the most extraordinary kind were often the result. In deciding this matter, it is well to keep in mind the follow- ing points: a. The information must serve all lines of work. It should tell the owner what the Jand is, upon which the entire forest enter- prise rests and depends; the proportion of good, medium and poor land, exactly as in farming. For Silviculture one must know site and species, and behavior of the species ; difficulties and dangers to be met and avoided. Utilization requires knowledge of material on the ground, topography, obstacles and advantages (streams, etc.) affecting par- ticularly transportation. For Protection the above, and also matters of debris, windfalls, fire and insect injured stuff and everything that affects the safety of this property. And it is not enough to know that a large windfall of inflammable material exists, but it is essential to know exactly where this menace lies, and what stands of green timber are endangered by it. Regulation and Administration require all the foregoing, and much more, and need to have all this information by definite location. b. The gathering of this information costs time and money and cannot be repeated, except at long intervals, (ten years, even in intensive work). Probablv over 75% of the money is spent in getting the man to and over the particular forty and not 25% is spent in actually describing the forty and measuring and tallying the timber. To save on this part of the work then is generally false economy. c. The man on the ground is the only man who counts, meas- ures, and describes with conditions hefore and around him; what he puts down. then and there, is fact, or, at least, it is fair estimate; *In one case the soil was evidently neither described nor examined regu- larly. and the final report stated that an area of about 60,000 acres was “sand over hardpan,” a condition probably not applying to 1% of the area. PRINCIPLES IN SURVEY 47 any later changes and inferences are guesswork and usually work away from and not toward the truth. If properly prepared this man can see and estimate numbers, sizes and other conditions and he can put down figures, etc., in fifty columns in little more time than it takes to fill twenty-five. In fact fifty columns, each asking one definite question, are more quickly filled than fifteen columns in which. more or less of a mixture of information is asked, or in which matters of judgment are demanded which require study on the ground. d. The printed form of description should ask the information in definite questions, one point at a time and in one column; it should make the work as simple as possible, discount memory, avoid all calculations and study and merely ask the field man to put down what he actually sees. Inference and suggestions for the future should be kept separate and not mixed up with recorded facts. Whatever is not definitely asked for in the sheet, is certainly never supplied regularly even by the best of field men. e. The man on the spot, if properly prepared, should be able to make a few important suggestions as to the future, and future treatment of the stand, and these should never be omitted. The man in the office who plans from this report may never see this particular stand: f. Wild woods are complex; they vary from acre to acre and a description such as is made by the Gerinan forester, where the stand is pure, uniform, even aged, cared for, and where soil and topography and origin and growth of this stand may have been described several times before, does not suffice. ‘g. Forest estimates and descriptions are made under conditions where it is difficult to control the work. The work, therefore, needs well prepared, honest men. And even then it should be inspected and verified all along; the field sheets and maps should be examined regularly. Men should be given ample time to do the work well; driving leads to mere thoughtless travel of the woods. 3. The Description Sheet. In the past forms with ten or even less columns were common: today about forty columns are used in the complete sheet (merchant- able timber and all) and the tendency is toward more columns. 48 FOREST REGULATION SAMPLE FIELD SHEET.

That numerical statements are much more definite, more convenient to make and compile, fully as expressive as words. If three classes of soil are made, it is just as clear and expressive to set figures 1, 2 and 3, as to state: good, medium and inferior ‘land, etc. » 50 FOREST. REGULATION c. Few stands furnish information for all the columns, but this is impossible to foresee and it is inconvenient to carry a variety of sheets, suited to different kinds of stands, so that a single form deserves preference. ‘The preceeding sample is intended merely as a suggestion; it is convenient to use; requires not over fifteen minutes for a full description at one station; and thus not over two hours per mile of line where descriptions are made every 220 yards. In uniform forests conditions, half that time suffices. The items are generally understood, and used, except, perhaps, the Stand Classes. These, as here intended, are merely a convenient division of. stands .on lines involving not merely age, and size, but also other conditions. Thus in pure stands of Norway Pine in the Lake States it may not be feasible to describe accurately by age classes; and while the caliper tally gives information as to sizes found on every acre of strip actually measured, and in part indicates age classes, there is some advantage in a further classification. The following classes are commonly found on a large tract of pure Norway Pine in the Great Lakes Region: All-Old over ripe stands, rapidly deteriorating, All-Old, fire injured stands, in uncertain condition, All-Old (even aged) good stands which may he safe for twenty- five years and more, Old broken stands with natural reproduction, Middle age, and “Second Growth” or “Pole” stands and Stands of “Reproduction” or thickets of trees 1-20 ft. tall. In this case it is easy to recognize the stand class and it is help- ful to record it, as it corroberates and amplifies other information. In doubtful cases it is of little consequence whether the stand is ..placed in one or in another class. Where this classification is em- ployed, it is well not to make too many classes, since then the difficulty of distinguishing them offsets all advantages of the classification. 4. Computation of Volume. This applies chieflly to merchantable timber. In the practice so far developed in the United States the volume of trees calipered or estimated for their diameter, has been computed from Volume tables. This is perfectly natural and proper, and will undoubtedly COMPUTATION OF VOLUME 51 continue to be done. Care should he taken to test the tables used; and tables based upon onc height for each diameter should not. be applied to stands of taller or shorter timber.. In emergency cases the form factor can be used to adapt the table. . European practice frequently uses the Draudt, or the Urich methods, but in most state forests the ocular estimate is permissible, and the use of Volume tables, like the old Bavarian tables is again coming into favor. Where the Urich method is used, recent instruc- tions, like the Bavarian of 1912, prescribe the felling of not less than 19 of the total stand for sample material to compute from. On a forty-acre lot with 6000 trees, this method calls for the felling of sixty trees, to he worked up into the usual stuff and measured and scaled. In Bavaria this is feasible in most localities, and readily indicates not only the total volume but also the grades and with this money value of the stand. In our country in localities remote from mill and road, the sixty trees and all the labor of cutting would be wasted. 5. The Mapping. This, in good field work, is now done on a scale of 8”, 12” and even 16” to the mile. The work usually notes: land division. topography, streams, roads, etc., forest types, burns, grazing and waste lands. Clean work avoids crowding of material on sheet, and especially the use of blunt crayon, etc., the ideal being a map which can readily be copied by anyone. Topography in mountains is commonly taken with aneroid; some form of “percentor” has advantages, especially in easy rolling and relatively level country. 6. Accuracy of the Work. In securing merely the amount of merchantable timber and especially in old, defective timber, the experienced cruiser has ad- vantage over a less experienced man, even with better methods. Generally, however, this is not true, and the results of the forester’s work, using methods which can be planned, criticised, adapted to conditions, checked at every step, and fully explained in court. deserve the preference. Nevertheless one hears occasionally: “But you are not accurate, a bridge engineer can estimate the amount of 52 FOREST REGULATION material, and the costs to one or few per cents and be certain of his figures, then why cannot you do the same?” But if the engineer’s material were scattered proniiscuously over miles of country, and no two pieces alike, and none of any accurate geometrical figure, none in position to weigh or actually measure, he would probably prefer not to estimate at all. Generally, ten per cent must be regarded as an attainable, and also a satisfactory accuracy in forestry estimates of volume. In most forestry work the estimate of the merchantable stuff is not used as final measure; the logs are scaled when cut, and it is usually far more important to have a good description, to record the condi- tion of the forest on a particular forty than to try for great accu- racy in the estimate of Volume. II. SPECIAL STUDIES IN THE FOREST. In the examination of large wildwoods properties it is usually desirable, almost necessary, to add the following: a. Preparation of Volume Tables of the important kinds of timber ; b. Preparation of Yield Tables; c. Study of the Behavior of the important species, and the in- juries of the recent past as well as the principal points of danger; d. Special study of conditions not really of the forest, such as grazing lands, camping grounds for tourists; peat, gravel rock de- posits, etc., which may, in time, become sources of income. a. Volume Tables. These tables give the volume of the individual tree and are usually of two kinds, one based on diameter breast high, the other on the age of the trees. 1. The tables based on diameter state that a tree 12” d. b. h. 14’, 16’, etc., contains a certain volume, either in cubic feet or feet board measure. They are useful, primarily, in the computation of the results of estimates or caliper measurements as made during the survey, but they give no information as to the rate of growth of the tree. To be of use for the timber on different sites (soil or altitude) VOLUME TABLES 53 they require values for different height classes. ‘he data for these tables are usually gathered in connection with regular timber cut- ting, so that the results may not only be stated in board feet or cubic feet, but may give the number of railway ties, poles, piling, cords of pulp or cooperage stock, etc., and in this way the value of the tree on basis of prevailing prices. This work may well be done by 2 men crews, and usually takes the following measuremetits: total height ; height of stump; number of logs, and total length thus actually used; clear length, and length which could be used; diameter breast high, outside bark; upper diameter of each log inside bark. The scale of the logs bases itself on length and diameter and leaves out of consideration crook and defect, as accidental. 2. Volume tables based on Age, state the volume (and usually height and diameter) of the tree, at the age of ten, twenty, thirty, etc., years, and thus indicate the rate of growth of the tree. ‘The data are gathered by partial, or by complete stem analysis. a. Partial analysis. Jf in the process above described, the rings on the stump are counted and thus the age of the tree is ascertained, the data can be arranged according to age instead of diameter and a table can be prepared which gives the volume of the tree at different ages. That the same data can also be used to prepare the table based on diameter, is evident. b. In Complete stem analysis the rings are counted on the stump, at the end of each log, and usually at one or more cuts in the top. In addition to being counted they are measured, from bark in, at every tenth ring, so that a table and a diagram can be prepared which shows the size of the tree at time of felling, ten years, twenty years, etc., before felling. From this diagram and table a curve is made for each tree and the rate for the several trees thus graphically averaged. ‘This is one of the most useful, instructive and reliable lines of measurements in forest work. As far as any one tree is concerned, the results are as accurate as the form of the tree permits. Only good trees should be used. A great deal of information is obtained from one tree; thus a tree 150 years old tells of its height, diameter and volume at ten, twenty, thirty, etc., years and thus gives accurate information, which in the partial analysis would require fifteen trees. In addition it presents the actual growth of 54 FOREST REGULATION a good tree throughout life, while the partial analysis does not give this for any tree. The information applies usually to dominant tim- ber, the kind composing the final crop. While, generally, a large number of trees are called for, it is surprising how uniform and how reliable is the information even from 100 trees. In all growth study work, only the valuable species are con- sidered. The study of growth on different sites multiplies the task and adds very materially to the cost. While apparently very simple and mechanical. this kind of work requires a well prepared, thoroughly interested and faithful worker.* b. Yield Tables. Present the volume of the Stand of trees per acre, at the age of ten, twenty, thirty, etc., years. They are, therefore, not merely tables of yield, but also tables of growth, indicating the rate of growth of the stand. For older stands (merchantable) it is desirable also to know the amount of material in form of ties, poles, etc., i. e., in the usual forms into which the particular timber is converted, and thus to learn not only the volume, but also the value of the stand per acre. Yield tables are prepared for the different sites, and in their final form usually include number of trees per acre and also height, diameter and volume of the average tree.** These tables assume a pure stand and even aged stand; all efforts to prepare satisfactory tables for mixed stands and for many age stands have failed, so far, to produce satisfactory results. To secure the data for yield tables it is necessary to find pure stands of different ages, get their volume and by means of curves even up and complete the information so that it can be tabulated. These stands should not only be pure stands and even aged, but also fully stocked and in reasonably good condition. For these reasons only good stands are of any use, and the selection of these stands * Ordinary Volume table work is done by two men crew; doing 50 trees . per day; office work adds 50% to cost; 1000 trees for about $200-$300. Stem Artalyses by two men crew; do abéut 10 trees per day; office work adds 100% ; total cost about $1.00-$2.co per tree. Varies greatly with timber, locality, ete. *: For models of completeness in Yield tables see the recent studies of growth of Pine, Oak, and Spruce by Schwappach. “YIELD TABLES 55° must depend on the judgment of the-man in charge of the work.. In ordinary wildwoods. the selection of stands for yield table work is not always easy, in some cases impracticable. It is much easier in conifers than hard woods, and generally easier for young stands than old. E,ven in pure stands, the variation in age, the irregular condition of the trees, and the questiom-of stocking, complicate matters. The question whether a stand. is fully stocked is not always easy to answer. The same stand of Pine 100 years old, fully stocked, and in excellent condition, might have 20% less trees, and yet 10% more volume if it had been heavily thinned at the right time. Here then. neither the number, nor the volume fully decide the case. his whole matter must remain debatable until new stands have grown up under the care of man, and accept- able standards established. Generally a fully stocked stand must’ be accepted to he one on which as many good trees exist as have fair growing space under the given conditions of species and site.* Since the Yield tables as above indicated deal with perfect stands, they have also been called Normal Yield Tables. Jn using them it is necessary to make allowances, for it is utterly impossible to develop all the stands of a forest through an &o or 109 year Rota- tion without disturbance or accidents. In the Bavarian Instructions a reduction of 20% for Spruce and 10-20% for Beech is suggested. Of late, Yield tables have been prepared giving the volumes over large areas as actually found. While these tables are of value as indicating actual conditions of the forest, their use in predicting the growth of timber on the particular site is rather uncertain, since the conditions of the wild woods are commonly too irregular and accidental to serve as criterion of what can be done in forestry. On the other hand the best 10% (or less) of all the acres of mature stuff calipered may very well be used in setting a provisional Normai Yield for mature timber and thus also serve to determine *This matter of Normality or what constitutes a fully stocked Stand (“Vollbestands factor”) and how a stand is to be gauged, is still a debated point. For purposes of volume-calculations the prevailing German plan puts: Degree of Stocking = Area of Cross Section of trees of Stand divided by Normal Area of Cross Section. See also: Martin, “Forsteinrichtung” and Schilling’s Comment in “Zeit- schrift fiir Forst und Jagdwessen,” 1911, p. 582, and particularly Fricke, “Standorts und Bestandesbeschretbung” in same paper, IQIT, p. 227. 56 FOREST REGULATION the normal average yearly growth of ripe timber, two figures useful in the development of the Working Plan. Similarly in mixed stands and many age stands, the actual Growing Stock of a fair number of the best stocked acres seems still the best basis for a provisional Normal Growing Stock and Normal Average Growth in these stands. In all cases the yield table results may well be checked by the use of Volume tables and by a comparison with established tables for the same kind of timber. A good set of Volume tables, especially where attention has been paid to the “growing space” or area of land occupied by the trees of different sizes, deserves attention. In setting the average age of the best mature stands it is well to keep in mind that the ordinary stand of timber (pure and even aged) does not increase, materially, in volume after a certain age, and that this age for most species is far within the limit of the natural Rotation or life of the tree. In the field work of gathering data for Yield tables, a task well done by the valuation survey crew, it is well to select the stands carefully and to be satisfied even with areas of one-half acre, rather than complicate conditions. In hard pine, etc., stunted, dense stands must be avoided ; preferably also very old stuff,-since future rota- tions will rarely consider stands over 150 years old, and the majority not over 100 years. Considering the many difficulties in the preparation of Yield tables, the question may well be asked: Why prepare these tables at all? The answer is: Just as a farmer wants to know, and needs to know how much wheat or corn he can raise on a given farm, so the Forester should know, and the owner wants to know how much pine timber will this property produce per acre and year. This is the function of the Yield table; and while the figures from wildwoods may never be very accurate, they will at least be near enough right to prevent foolish investment and utterly mislead- ing statements, such as have already been circulated about Eucalyp- tus, Jack Pine, Norway Poplar, ete.. in our country, and they will also prevent costly planting on miserable sites and equally so the unwise penury of leaving good lands idle for want of proper plant- ing. Jn the regulation of large forest properties, even approximate figures, if rationally based, will give assurance of continued supply, by preventing thoughtless overcutting of the forest. YIELD TABLES 57 c. Forecast Tables. These have also been termed Yield Tables. ‘I'hey state (fore- cast) that if, for instance, the stand is cut over to a diameter limit of 12’, there will be a growth sufficient to make 3000 ft. b. m. in twenty-five years. They are based on the stand of timber left after cutting and its estimated growth, the assumption being that a certain numter of trees die (estimated) and that the forest continues to reproduce as in the past, and that the composition in mixed forests continue as at present. Since these tables are bascd on the present, more or less acci- dental conditions of the wild woods they apply only for the im- mediate locality and for the immediate future. d. Other Studies in the Timber. These involve chiefly the behavior of the important species of trees on the property. 1. Behavior of trees, notably: a. ‘Tolerance. h. Site requirements, chiefly as to soil, and in mountains as to exposure and altitude. c. Hehavior of principal species in mixture. : d. Reproduction, frequency of seed years, abundance of seed- ing, etc. In hardwoods, also, the sprouting. These facts as gathered at the first Valuation Survey are, of necessity, merely beginnings. The behavior of trees in any locality is not learned in one vear, and experience must accumulate. For this reason such a line of inquiry is treated briefly and * Tables of this kind, though evidently worked out with a great deal of care, have not given us very satisfactory or convincing data. The following figures are taken from four different publications. The growth per acre and year of a stand cut to 12” d. b. h. is as follows: Spruce (East) cut takes 2490 ft. per acre, growth is 103 ft. Loblolly (S. C.) cut takes 6190 ft. per acre, growth is 73 ft. Pine (Ark.) cut takes 6060 ft. per acre, growth is 150 ft. while according to recent studies the growth of Loblolly in Maryland on Site II, or average lands, is over 400 ft. per acre and year. Here a fast growing species in a warm climate is expected to grow only 75% as much timber as another stand of slow growing stuff on a cold site, and this in spite of nearly double the growing stock on the land. 58° FOREST REGULATION details deferred. Effective study of this kind requires a man thor- oughly grounded in silvics, and if he is not to ke had, it should ke left at notes as gathered in Valuation Survey. ee 2. Injuries occur in all woods. They represent the dangers to the Merchantable Stand, present and future, and danger of im-, mediate loss. They determine what must be done to protect the forests and often decide what species must be favored or used and also the methods of silviculture best adapted. Windfall prevents the use of various forms of seeding from isolated trees, and groups of such trees ; it forbids shelterwood and seed tree in Spruce. Heavy snow forbids the use of Scotch. Pine in parts of the Black Forest; the Locust beetle has prevented desirable woodlot work on the farms, etc. , a. Generally the forest tells its own story, and notes are gathered during the regular valuation survey. Besides occasional stops to determine the approximate age of a burn or other injury there is no call for special study unless some great trouble, like bark beetle pest, etc., is under way and threatens large values in timber. Manner of stating these facts in report should avoid all lengthy discussion and relate the injury directly with loss in value, its effect on Protection, Utilization, Silviculture, Business. If special study. is made of such trouble as an insect calamity, it is best made the subject of special report. b. Special consideration is required by the conditions affect- ing fire protection. In the United States this must continue for many years, in fact until the woods are cleaned up and fire protection becomes an established custom. In this connection the areas of even aged dense young stands in conifers and the large masses of windfall and fire killed stuff require attention and are therefore recorded in regular columns of the description sheet. To try to locate at once the best points for lookouts, tool boxes, phone lines, etc., is really beyond the scope of the survey and is much better done as a special enterprise in making the Plan of Protection. e. Report on Conditions other than Timber. Which affect value of property and its management. Such matters as: Lands needed for purposes of the forest business, mill sites, pastures, etc. CONDITIONS NOT TIMBER 59 Grazing areas. Water powers, mileage of driveablé stream, etc. Camp grounds for pleasure seekers, Rock, gravel, etc., or materials which may he disposed of or used in the work on the forest. 1. In ordinary valuation survey these.matters are merely noted as they appear to the forester. ‘here is no time for exploration or study. If sufficiently evident and important they are made subject of special examination or else they are left for others to explore, as is usually the case in development of these special resources, where the future applicant does the prospecting and calls attention to the matter by request for purchase or lease. 2. Where grazing Jands are of importance as on many of the National Forests, their examination is made a special task. The land is covered in a manner similar to that used in valuation survey of forest lands; and the facts are noted on a regularly prepared form in which the following items deserve consideration : a. Area and topography and altitude. b. Soil and drainage. c. Cover, grass, or brush or both, kinds and density. d. Quality of range by certain standards, 1. e., 1, 2d or 3d class grass lands, etc. e. Injury, if any and cause of this. f. Possibility of improving range. ; ge. Suggestions regarding treatinent in the immediate future, to which should be added: Time when free from snow, i. e., open season: tinie when ready to drive in; capacity to carry stock for this open season; access to area, and possibility of giving each man a separate range. III. INFORMATION NOT OF THE PROPERTY ITSELF. While this is now commonly omitted in Germany, it is of greatest importance to us, where everything is new and changing, and where the owner may ke in New York and the property in Michigan or Idaho. ‘ 60 FOREST REGULATION a. Logging or Exploitation, Methods and Costs, Effects on Forest. This usually involves: 1. What is done in this Vicinity with the Kinds of timber found upon the property. How much is cut, where, and by whom. 2. How is the work done, i. e.. Methods of Logging, trans- portation, milling, including matters of labor, usual results and cost. Particularly the methods of logging and transportation of timber to mill require special study, and the principal steps of felling, ctitting into logs, skidding (or varding) loading, hauling, driving or rail- roading, the construction of roads, railway, camps, etc., all need mention. 3. How is the Material marketed, where and at what prices, including the consideration of value of material at different points, as logs in woods, at mill, as stumpage. 4. In what condition do these methods of logging leave the woods from standpoint of silviculture and protection. 5. Names of men who take contracts of logging, buy stumpage, or logs, and mills ready to convert timber on contract, etc. 6. Suggestions for improvement especially as to a. Silviculture and Protection. b. Economy in logging. c. Opportunity of manufacturing the stuff by owner. This set of information is very important, it is largely a matter of visits and canvass or inquiry, requires tact and preparation, and often can only be done through special, extended study by some person of considerable experience. In districts with special forms of exploitation such as Turpentine industry, tan bark, acid. pulp and extract wood ; railway ties, poles, piling, cordwood jobs, cooper- age, wagon stock, etc., these industries require attention. b. The Market. Needs special study, and includes both local markets and dis- tant (usually large city) market as well as rates of shipment to these markets. The large “World Markets”, i. e., the big cities, at a distance are known, the prices paid or demanded are seen in ‘S‘echnical OUTSIDE CONDITIONS 61 Journals, freight rates are obtained from Railways or shippers. It is desirable to know the firms now buying in the district where the property lies, and specializing in the kinds of timber on hand. Local Market is of special value. Here come questions: What is bought, how much, who buys. Then also: what is the history of this market for last few years, and what are the chances of improvement by property owner by: Special inducement to present buvers. 3ringing in other or additional industries. This information, also, is a matter of canvass, reauires tact and time. Lut the salient points can always he secured and should never be wanting. even if much correction is needed later on. c. Population and principal Business of the District. Chief considerations here are the effect of the people and their business on: Taxation, Protection, Labor, Market. In many dis- tricts as in the Iake States, taxation has heen boosted systematically by local people until cutting has been forced; grazing in the West opposes forest extension and good silviculture and in some cases ordinary fire protection; grazing in the Southern Pinery established the custom of “light burning’ and prevented reproduction ; the berry picker in Lake States Pinery and the tourist in many districts must be considered in fire protection, etc. Lack of labor in places prevents effective fire fighting in spite of all patrol and lookouts. The established custom of wood working in parts of the East, Lake Region and Canada, makes a cord of poor material (Aspen, tama- rack, etc.) far more valuable and saleable than is the same material forty miles from Detroit. This information is gathered while looking after markets, logging, etc., and should be constantly in the mind of the Forester as he examines property. d. Contracts for Timber, Leases of Lands, Easements, Etc. Which may exist, are known to the owner or his agent. But the effect of these contracts on the forest, and especially on future management, are not usually known or understood. Such contracts are very common. In many cases it is a contract for all standing merchantable timber; or for certain kinds of timber (Hemlock and Cedar in Lake Region are preferred subjects), in some cases there 62 FOREST REGULATION is no time limit at all, in others it is a long time contract without limitation as to area. so that the man can return to the same lands and cut over the same tracts repeatedly according to changes in market. ‘The effect of such conditions is evident; and all rational, systematic treatment of the woods is impossible unless the contract is removed hy purchase, or is modified by agreement and compensa- tion. The statement should point out clearly what the contract is, its history to date, injury to the forest at present, interference with the management in future. and suggestion as to its removal. e. General Topography or Lay of Land and Drainage of the District. a\s it affects transportation, agricultural and other development and thereby future market, labor, and protection and the value of the property itself. This is generally not subject of personal in- spection but is matter of maps and inquiry. Important here: General altitude as it affects climate, agriculture, etc., best stated in per cent of total as: over 60% above 6,000 alt., etc. ; topography, i. e., what per cent is steep lands. mountain slopes, not fit for farm- ing; streams draining the dictrict, their value for driving timber, for water power, in some cases, for ordinary navigation; the stream valleys as natural lines of travel and railway construction. Swamp areas, areas of waste land and possibility or likelihood of reclama- tion. This means a brief statement of the great permanent condi- tions of the district which must always affect its development and are of importance to the particular property determining its value as a business. f. The Climate. . Next to soil, and in many cases far more than soil, is the most important part of Site; it determines Species, it affects reproduc- tion, growth, final size, and quality of timber. It also affects protection and exploitation or utihzation and income and value of property. 1. Warm climate and long growing season produce a J,oblolly Pine 24” diameter at forty vears in Georgia; while a cold climate produces a 14” Spruce at 150 years in the Adirondacks on better soil. The drv spring following the snow melt in the Lake Region and Ontario means a regular spring fire season: moist and even CONDITIONS OF DISTRICT 63 climate of the Southern Pinery has prevented any serious forest fires ; the peculiar continental climate with its occasional dry years must always mean a special feature in fire protection; the deep snow fall of the Adirondacks or the North Rockies discourages pine and calls for Spruce or Balsam; the snow and ice road will always be a factor in logging in the North Countries, and absence of snow in the South will call for railway and wagon haul, etc. 2. In all cases the effect of climate on silviculture or the raising of the crop far outweighs all other considerations. 3. Usually the general climate of a district is known and much information can be secured {rom the weather bureau reports. What is wanted here is not long tabulations of relevant and irrelevant matter, but brief, preferably tabular statements to show exactly what the temperature, rainfall, frost, storm, etc., are for. the district and point out in what way and to what degree these conditions affect silviculture, protection, exploitation, etc. Particular attention to length of growing season, temperature and precipitation during this period, frosts in spring and fall. Then also long dry spells, their regularity and effect on forest, especially on fire protection; storms, periodicity of these, direction and severity, regular storm roads as in the Gulf Region and in mountains. 4. In level country (Great Lakes, South) the information on general climate of district quite suffices, but in mountain country this is not true. Here every valley has its own peculiarities; the direction and intensity of wind changes with every slope; the rain- fall around the Olympic Mountains in Washington, for instance, changes from over 160” on west side to about 30” on Northeast side at Port Townsend al! within the same National Forest. 5. It is evident that the Forester, in examining a property, can not possibly determine all these facts. But he can always get the general climate from the Weather Bureau, and he can usually gather considerable information from local people. Particularly on points of long dry spells. time of early snow, depth of snow fall, usual snow melt, character of spring season, etc. Here it is not a matter of accurate figures, but rather of experience upon which the people rely in their business affairs. 6. In addition the Forester may safely infer from the char- acter of tree growth and other vegetation, from the presence of large burns, of parks, and grass lands, of sage brush slopes, etc., 64 FOREST REGULATION with regard to local climate in different parts of property itself. In recording it is well to state the basic facts, and leave the inference to follow. For instance if 10% of the property is steep north slopes, in latitudes north of 40° the inference is safe that these slopes are dark, and cool or cold and relatively moist, etc. Similarly, the Spruce Slope in West Virginia, or in the Rockies warrants the inference that the climate here on these slopes is cool and moist; and south slope in Rockies, covered with sage-brush requires no ‘meteorological investigation, the vegetation here tells the story more accurately than weather observations. g. Present Organization, and Expenses, Or Personnel maintained and necessary expenses incurred in connection with the care of the property in past years is usually known to the owner. Nevertheless it is helpful to state these facts and point out what portions of this personnel is replaced by a regular forest organization. It it also well to point out the insufficiency of present organization and consequent losses, or possible losses. Usually there is an attorney in a nearby town to look after tax and trespass cases; a variable sum spent in cruiser services, etc., to look after, and more or less, protect the property. In many cases, as in the Adirondacks and the South, ‘‘caretakers” are employed to look after buildings, roads, etc., and usually these men are rather expen- sive, rarely efficient, and never concerned in the forest itself. It is not uncommon that the owner spends twice the salary of a good forester ‘on a few men entirely devoid even of interest in the growing forest. IV. LIST OF LANDS. The owner, or more often his local attorney usually has a list -of all the lands making up the property. Commonly this is in the form of: a) Township plats with lands marked in color. hb) Tabular statement by township. range and section, and forty in United States survey Jands or “Public Lands States.” Such a list and set of Plats should accompany any complete Report such as is here contemplated in connection with a Working Plan. In addition to the mere “description”, such-a list should also LIST OF LANDS 65 indicate what part of the loundaries has been inspected and when, and the condition of these lines, blazes, and monuments. In many cases certain areas or lines are in dispute; then also lands ender timber contracts, etc., should be shown on plat and in list. in many cases time of purchase, of regular land survey, title, etc., are of interest even in the matter of making a Working Plan. In all cases where portions of the lands should be eliminated and sold for agricultural purposes, the lands should receive special color on the plat and note in list. V. DETAIL DESCRIPTION, NOTES AND MAPS. After all or any considerable part of the field work is done the field notes should ke copied and one copy, at least, stored in fire proof vault. The material. ‘his is quite a bulky affair. For a forest of 50,000 acres, and if done by lots of eighty acres each and maps of every section, there are over 600 sheets of description and tally, and perhaps over 100 separate maps. ‘wo ways now are open: Ordinary clerical help may copy, or clse an expert, preferably the man in charge of the field work copies, studies and condenses. In the former case, it is safest to allow the clerk no change of data whatever, 1. e., have it copred as it stands in the field notes, except the tally sheet where he can well substitute number for tally dots and lines. Where the forester copies, the following will prove suitable. a. Copy descriptions by Lots on same kind of sheets as used in the field, one sheet for one lot only. hb. Condense the descriptions for each Suk-Lot into one de- scription per Sub-lot, 1. e., where a Sub-Lot in field receives two or more descriptions (common if well done), these descriptions are: combined and averaged. and the volume of timber computed for entire Sub-Lot so that one line and one description suffices for each sub-lot. This requires expert knowledge, preferably personal knowledge of particular forest lands and it also requires interest and care, for in this task the first valuable record of the property is laid down. c. ‘These Lot sheets are then filed in regular order by Town- ‘ship and Section, or other system. 66 FOREST REGULATION C. COMPILATION OF THE INFORMATION IN A REPORT. 1. View Point. Whether the property belongs to state, or to a man in New York the report must keep in mind two kinds of readers: a. The Owner in New York or the Member of a state Com- mission usually a non-technical and very busy man who cannot study a Jong report but is willing to spend a few hours to get the principal facts as they concern him. For this man a one or two page resumé is very helpful, but also the rest of the General Report should be in such form that, if he cares, he can readily find and understand the desirable information. b. The Forester who is to use the Working Plan. He is technical, critical, and for him the general Report should not only be brief and clear, but also quite complete, and it should refer to detail descriptions and notes and maps in such a way that he can readily verify all statements. 2. The Arrangement of the Material or the Form of the Report. Keeping in mind the custom of stating the more general facts first, it is usual to arrange the matter as follows: a. Outside Conditions, or conditions not really part of the property. Here belong: Location, and description of District in- cluding lands and topography and climate; then also the population and its industries; the markets and transportation: also special forest industries, logging and milling, though these latter might well follow the description of the property. b. Description of the Property, including J.and and ‘Timber, Improvements and Business. Tables are more telling than text, but long and complex tables, requiring extensive study, are rarely properly used. 3. The Compilation. The ficld maps are copied and compiled into larger maps on a smaller scale. and traced for white and blue prints. In compiling the forest descriptions and estimates or Tally Results it is well: a. Jo decide first on the form and contents of the General Report. COMPILATION OF REPORT 67 b. To make several separate tasks of the compilation. ‘Thus to make one compilation for the data referring to the land or site; another to the merchantable timber ; one to the aze classes, to repro- duction, to future treatment, etc. c. ‘lo prepare a regular table for each of these tasks, following the field sheet, and adding columns only where it saves time or adds clearness. In this work, as in field work, it pays to use plenty of columns, and not try to have one column tell several facts. Jn taking off information from field sheets on these compilation tables it is well to add the data for each section. In this way the information is at once “bunched”, as far as this is convenient by larger units. The same may well he done for each Township. c. The Volume and Yield Tables are treated in the usual way, by condensing into general tables and diagrams. d. For the notes regarding logging methods, markets, injuries, ‘and then also climate, etc.. no special directions can Le given. They should be condensed to brief, clear and yet complete statements, and should never lose sight of the real purpose which they are to serve. 4. The General Report. This is a very important document. In most cases it is the first reasonakly complete and fairly accurate statement regarding the property. Much depends on its form, size, stvle and arrangement. ‘The hest work in the field may fail to serve through bad compilation and unsatisfactory presentation in the Gencral Report. The following sample report does not pretend accuracy of detail, completeness or style. but is placed here merely to suggest how this kind of task mav he done. D. A SAMPLE REPORT. Report on Forest property of John Doe, located in ........ County, Mich., comprising 50,000 acres. I. Outside Conditions, or General Conditions of the District in which the property lies. a. Lands and Topography. Level, gently rolling country. typical Michigan Pinery, 10-20% swamp lands. Land covered with Glacial Drift, largely deep sands and loamy sands, the former Pine, the latter Hardwood and Hemlock lands: over 60% of all lands 68 FORFST REGULATION cut over (logged) and mostly burned over. Numerous streams, with clear water, and moderate fall, some good waterpower ; streams driveable for soft woods, no regular navigation. Qver 10% of land area in fine clear water Jakes. b. Climate, typical of North Michigan and Lake Region. 1. Temperature: Jong severe winters, with much zero weather. short, but rather warm summers. Too cold, i. e., north of the natural limit of Hickory, Walnut, Chestnut, Sycamore, ete. ; tco cold for corn as crop. Low temperature and short season result in slow growth, small amount of seed; affect sprouting of some of the hardwoods. On the pine land the sand heats up in summer to peint of injury to seedlings. 2. Precipitation, about 30” per vear; comes largely as snow. Iry springs produce a regular spring fire season. Summer com- monly quite dry. Extremely dry seasons at intervals of 6-10 vears have caused great forest fires of which 1877, 1881, 1804, 1907 and 1908 are famous. In 1008 practically no rain from May to October. Snow deep and can be depended upon for sleigh haul. Usually over 100 days of good sleighing. Covers seedlings ; but deep wet snow breaks much timher.. especially young pine. 3. Frost, especially late frosts, severe and injurious to native forest trees. In 1907 and 1913 late May and June frosts killed new foliage on Oak, Aspen and even killed young pine. Frosts may occur in any month. 4. Prevailing winds West and Northwest and Southwest, the latter quite drv, often hot and injurious. Windfall not rare, acci- dental, i. e., no regular storm roads. c. Population and Industries. 1. The population of county is about 7,000 and has been nearly stationary for ten years; the area is about 360,000 acres. Poputa- tion mostly in three small towns; dependent upon the forest indus- tries. -\ sparse rural population, likewise still depends largely on work in logging camps and mills. 2. Population is the usual American mixture, which gathers in forest districts; no colored or Indian settlements. 3. Sentiment favors agricultural settlement and clearing of lands and is kept alive by local papers, merchants, land dealers, etc. SAMYPLT, REPORT 69 4. Labor is fairly plentiful, and quite efficient especially in woods work. 5. Timber trespass and carelessness with fire, in clearing. road-building, etc., still prevails and is not properly restrained by the authorities. 6. Taxation is high; twenty-one per AIill average for county. Increased settlement calls for roads and schools and may increase tax rate for near future. 7. Agricultural Development is slow. only 11% of county now: improved land and only 3% has been added in ten vears. 8. Mills: Three sawmills, capacity about 50 M. ft. per day are located in........ CIEY tere concedes ANG 26 6 Gan tes ,and employ........ men. Seventeen small “portables” also operate in county. Exploita- tion of Cedar and Hemlock Bark amounted to $........ in past year. Outlook: Two larger mills were moved away, and two small villages abandoned in past five years. Generally the local industries (except farming) are on the decline. Timber (as logs) goes out of county to ........ city where a closer utilization is possible. 9. Tourists, fishing and hunting parties come into this county in considerable numbers. This affects protection but may also be made source of income. d. Markets and Transportation. 1. Local Market. The mills, including the portables, then also agents of distant concerns come here as buyers and take prac- tically everything including Jack Pine, and Tamarack, and even dead stubs of Pine and hardwood tops (cordwood cut in 4 ft. length.) The mills at ........ city contract for logs of all kinds loaded on cars or delivered at track, and also contract for stumpage. 2. Prices at present are as follows: Pine logs $18.00 per M. ft.; stumpage, $12.00. Hemlock logs $10.00 per M. ft.; stumpage, $6.00. Etc. 3. Prices have advanced over 100% in fifteen years, and are rapidly advancing for all kinds of material. This “price growth” is estimated at 4% per year for Pine, Ash, Basswood, Elm and Cedar. 5% for Hemlock and Maple. 8% for Beech and Tamarack, and represents the most important growth on the property. 70 FOREST REGULATLON a.

Logging is “clean” here now, i. e., all is cut; much of material does not pay for removal; logging destroys the forest, leaves slash, and is usually followed hy fire. g. ‘here is still about one billion feet of timber in this county and this is now being logged at rate of fifty million feet per vear; about 30% Hemlock, 24% Maple, the rest Beech, I'm, ete. h. Cedar and Tamarack is exploited entirely in small way by local people: ties cut and hewn at fitteen cents per tie, poles cut and peeled at thirty cents—seventy-five cents a piece, etc. Hemlock bark is peeled and stacked at $1.50 per cord. > SAMPLE REPORT 71 i. The methods of logging are well suited to conditions; efforts at using machinery have not been a success. .\ closer utilization of hardwood tops has begun and will help fire protection where the forest is to stay. II. The Property. a. Area and form. The 50,009 acres are Iccated in four town- ships. they comprise fifteen different pieces separated by numerous outside holdings, of which over 80% have been logged and burned over in last twenty years. The largest solid body is 5,600 acres, the smallest, eighty acres; most of the area is contiguous, i. e., the hodies “touch at corners.” b. Topography and climate are the same as for the county generally: it is a level and gently rolling country, with a few tracts of “pot hole’ lands, and also a few small areas with rocky “hog backs.” The land is drained bv Wolf. Beaver and Deer Creeks, all fol- lowing into the........ River: all drivable for soft timber. total length drivable streams forty miles. c. The land is all covered with drift, the soil is sand and sandy loam, very little clav. and is generally over fifty feet deep. The land is classified hy the timber it bears; the hardwood and Hemlock lands are generally considered farm lands in this district. About 60% of these could well be farmed, of the pine lands not over 10% and of the swamps not over 10% would pay for drainage. About 2000 acres is open moss bog and may he regarded as waste land at present. Classifving the lands from the stand point of growing timber, and using lav of land, size and appearance of timber, and yield per acre as principal standards we have: TABLE OF SITES, i. e., Good (1), Medium (IT), and Poor (TI1) lands for growing the timber named. ‘ Site for Site for Site for Site for | Waste Types Total] Norway Pine.| White Pine.

Fires run most on pine land, little in swamps, except in specially dry seasons, when swamp fires may be the very worst. Fire season: After snow melt, on pine lands, soil dries and warms up rapidly and fires start in this district every year. Fire causes: Clearing land; Railways (along........ branch) also campers, fishermen, tourists and berry-pickers. Help in fire work is quite easy to get and efficient. Cooperation: Association now organizing; arrangement with local people practical and promising of good results. Fire patrol needed: Ordinary years not over two months in year. Special years, May-Octoker; perhaps once in ten years. “Look outs” indicated especially on Pine land areas. Fire lines needed in Pine lands. 2. Insects: Sawfly has injured over half of all Tamarack. Insects also work on Pine land areas, injuring young stuff, even Jack Pine. 3. Late Frosts severe until end of May, some years in June;. kill back new foliage on native trees. 4. Heavy wet snows break down young timber, notably Pine, every year on this property. 5. Ice on trees is a common trouble and destroys much timber and opens up Crowns to disease. 78 FOREST REGULATION 6. Wind storms have caused several large windfalls in Sect.... and. ‘Settu..... ; thev are rare, accidental, i. ¢., there is no regular storm road here. 7. l)iseases of trees have caused large amount of defect, in all kinds of timber: but the matter is no worse than may be expected in al! old stands of wild woods and therefore needs no special consideration. 8. Timber trespass is a common trouble here, it will continue and even be worse as more people come into the district. QOnlv a recular organization. patrol. ete., will prevent this loss. k. Timber Contratts, and Rights of Way. Two contracts exist for timber: 1. J. D. has contract for all Hemlock in Sections:....... The contract runs for twenty years and ends 1922. Price $3.09 per ML. ft., bark thrown in. No limits as to area, he can come back over any area if he likes. ‘his contract means that ]. D. has a right to cut and exploit all over this area until 1922: and while his work has not been worse than that of others, it does: Break down hardwood timber not ready to be cut. leave, in places, large masses of Hemlock tops. Keep people in the woods during summer peeling bark, and in fact. at all times. These people need watching. Prevent any proper treatment of these lands. Would recommend one of the following: Suy off J. D. outright. He has still standing here about ten million feet and it is worth to him about $5.00 per M. ft. As he pays only $3.00, an offer of $2.00 per M. fi. may tempt him. Follow J. D. with a logging job and reduce the loss through his work. Jn this case it is worth at least $1500 to get some compromise which will make J. D. work the land over according to some definite plan, agreed upon, and also to contract, not to return to any lands once cut over. 2. X. Smith has a contract for the Cedar in Sect........ The contract runs for ten vears, ends 1915, prices: Poles: size 25 ft......... size 30 ft......... , etc. 0 , etc. SAMPLE REPORT 79 No restrictions, no re-arrangement of prices. Little is to be said or done about this Contract; it was a mistake financially, the stuff is worth twice what he pays for it. 3. The J. & R. Co. have right of way for their Logging Rail- way through Sect......., about ten miles in all; they paid for all timber cut, but were not compelled to clear up brush. They banked all tops on koth sides of right of way right into edge of timber. Also, they make no effort at fire protection by spark arresters or patrol. This should be remedied and arrangements for this should he made with the Company. It is worth $2000 to the property to get this done. 1. Expenses and Present Organization used in taking care of the Property. 1. Taxes. Assessment at full value (by law) is as follows: Hardwood and Hemlock timber.15000 acres at $15—$225,009 Pine timber .............--.-5 5009 acres at 30— 150,000 Swamp timber ............... 4000 acres at 5— 20,000 Cut over lands .............-. 26000 acres at 2— 52,000 $447,000 Tax rate 21 per 1000 .”. Taxes total $9387. Assessments are still on increase, and even the rate may in- crease considerably, as it is now up to 35 per Mill in some parts of the county. “The average tax rate for county is 21 per Mill, for the State 17 per Mill. The State has not begun to consider a rational system of forest taxation but is expected to do so in near future. The preferred form as at present’ discussed is the flat rate on soil, together with a 10% stumpage tax at time of cutting. 2. Other expenses, yearly: a. Local attorney as agent, retainer per year...........$2000 Looks after timber contracts, tax affairs, trespass, and engages cruiser, etc., to examine lands at times. b.

Notes with regard to the foregoing Sample Report. i. There is no effort at exact Age Classes. This seemed un- neccessary since the field data in this forest, especially the Hardwood type make the Age Class work largely a rough estimate or a matter of mere size. z. Matters of Improvement and Lusiness were left out, and the subjects of Volume and Yield Tables merely indicated. 3. Similarly the nature of the case prevented many kinds of interesting forest affairs and conditions from appearing here, not- ably: Turpentine Industry as it exists in the South; Grazing as practiced and important in the West; Fish and Game affairs as they exist in Europe and also in some of our Eastern forest properties. The manner of treatment of these may he inferred from the fore- going; the principles are the same; each is treated in its relation to the Business (Income and Expense), Utilization and assurance of future supply, including its effect on Silviculture and especially Protection. PART III. PLANS. GENERAL PLANS. A. GENERAL CONSIDERATIONS. a. General Plans and Detail Plans together form the Work- ing Plan proper. Reports tell the owner what he has, Plans tell him what he can do. b. The General Plan usually applies to the entire forest or property (“Revier” in Germ.), the Detail Plans for Protection, for Improvements, for Planting, etc., also apply to the entire forest, but Detail Plans for Regulation of the Cut in Amount and Location, and consequent Regulation of Age Classes do not always apply to the entire forest, since each Working Section reccives a separate Plan. Where a forest is small and uniform in Site and Stands, the entire forest may have but one plan. But even the General Plan in its directions as to Species, Silviculture, Rotation, takes up the matter by Working Sections. Large forests, such as some of our National Forests will require special treatment, and may better be divided into several parts, like so many distinct properties, each with its distinct General and Detail Plans. c. ‘he property, the Forest. composed of land and timber, is assumed to ke used for the purpose of raising timber and the plans must tell what should be done to make the best possible use of this property. 3ut the purpose is not always the same. .A forest in Wyoming may ke as valuable for its grazing possibilities as for timber; in Wisconsin it may be merely a matter of raising timber; in the pinery of Alabama it would certainly also be used to produce Naval Stores: while in Maine or Washington the waterpowers, tourist Tusiness and hunting and fishing epportunities might outweigh the 82 FOREST REGULATION raising of timber in importance. Accordingly, even the Gencral Plan for the forest is not always the same, but varies with locality. d. The General Plan as well as Detail Plans are not fixed affairs, but change with time and development. In Germany the plan of Protection may be omitted entirely because protection here is old, and there is nothing to be modified. In the United States, on the other hand, the plan of Protection may be and often is the first and most important plan to make and develop. e. The distinction between General and Detail Plans is not sharp and consistent. In Montana the Grazing Plan would be im- portant and deserve a place in General as well as in the Detail Plans; in Michigan grazing, if allowed at all, would be a trivial matter and form part of the Detail Plans of Secondary Utilization. f. General Plans deal with all large and important features of the enterprise. ‘Chey sum up briefly dominant conditions; outline methods to he used, and the object to ke attained. Usually they cover: 1. The objects of the forest-business, or the objects of the owner in buying the forest and conducting this business. 2. Species, or Kinds of timber which the forest is to raise. 3. Methods of Silviculture, or methods to be employed in raising the crop of timber. 4. Rotation, or how old the crop of timber is to be when cut. 5. Regulation of the Cut in Amount and in Location, condi- tion of Age Classes, distribution of young and old stands on the property and a plan for greater regularity in Age Classes and more satisfactory distribution. The above five topics usually make up General Plans in text- bocks treating of the old settled conditions of the state forests abroad. In a new country like ours, and wherever new enterprises are to be developed, several additional lines of work require atten- tion in these General Plans. Among these are: 6. Plans of Improvements, particularly the development of roads, trails, telephone lines, suitable housing for help, ete. 7. Plans of Utilization, or plans of logging timber, policies and regulations in cases of timber sales on stump, and then also plans for secondary utilization, such as grazing, turpentine, tan bark, ete. GENERAL PLANS 83 8. Plans of Protection, chiefly fire-protection. Risk, danger points or areas, danger-months or periods, proper patrol, most cffective improvements, the organization of extra help, and co- operation. 9g. Estimates and Apportionment of Income and Expenses together with a statement of Personnel or help. Where parts of the lands are used for water power sites, tourists’ camps, etc., a definite policy or General Plan for these enterprises should be worked out, but this is no longer within the sphere of forestry proper, and therefore need not be considered here. B. THE OBJECTS OF MANAGEMENT. What do we keep and develop the property for?- a. In Central Europe the object is, generally, to raise crops of timber most demanded in the market. This applies to over 90% of all woods. Apparently this is the desire of the owner, and is made much of in the books. Lut in reality it is more a matter of condi- tions than of desire. In a number of States the law compels the owner to stay in the business of forestry and do it reasonably well. Fven where he has the liberty to clear land, he must chose between forestry or clearing. In the latter case he ceases to be of interest in this connection. Where he stays in forestry, it is good business, site and market which determine for him the limited choice. In mountains the climate forbids raising Oak, etc., on the sands of North Germany the site compels him to use Pine. b. In our own country the same will be true. While a farmer in the Ohio Valley may raise a variety of timber, practice Coppice and Selection Method, etc., the owner of larger forests rarely has a like range of choice. In the Northern Spruce region it is generally Spruce or scrub hardwoods; Spruce alone pays and the choice of the owner has little play (provided it is to be a forest and not mere game park, etc.). On the sands of the Lake Region and South, in the Lodge Pole forests of the Rockies, in much of the Yellow Pine, and in all Alpine woods of the West, the Site decides, and the owner has merely choice of forestry or not forestry. Ile may be penurious and fail to provide funds for protection, etc., it is trie, but this will 84 FOREST REGULATION readily lead to devastation and ruin, and the ownership will change. The desire of the owner is also limited by market. The owner may desire to cut Lodgepole at sixty years of age, but if it takes 150 years to get a railway tie, and ties are the smallest stuff his market can take, the desire of the owner is of little consequence. c. In the United States at the present time woods are held ina great variety of ownership and conditions of market, transportation, etc., so that the immediate object of holding timber at present varies from that of the small lumberman who buys stumpage for immediate cutting to that of the National Government in its per- manent policy with regard to large holdings in National Forests. In the one case there is no thought of forestry, not even protection, the forest is merely a mass of logs on the stump; in the other it is modern forestry, good protection and well planned utilization and silviculture. In the former case no plan is made, none wanted; in the latter case we find great activity in perfecting knowledge concerning the forest, constant planning and a prompt adaptation and modification to meet new requirements and to use new information. Numerous intermediate cases or conditions exist, and for that reason we make and will make for many years to come, a variety of Working Plans, which will differ as to completeness and emphasis. Some of these will be little more than Plans of Protection (chiefly against fire), others will lay stress on utilization, while still others will introduce improvements and the beginnings of Silviculture. The following cases of ownership affecting present objects of holding timber appear of interest in the United States now: 1. Woodlot of the farm. If this is permanent at all, the object is to produce a home supply of fuel and other timber. In New England and the South, larger woodlots produce for general market and approach regular forests. Usually land is relatively good, market and convenience cf getting out material are of the hest. and there should te a good return from the soil. A plan for the most intensive form of forestry is justified for this class of important forest lands. 2. Forests of the Lumberman Owner: vary from those of the small owner of stumpage to be cut at once. to the holdings of OLJECTS OF REGULATION 85 supplies for thirty and more vears. Jn the past, the plan of handling the forest consisted in directions for most economical exploitation. To this has been added in last fifteen years, plans for protection by individual effort and cooperative enterprise, and in a few cases even plans for a systematic cutting of timber, at least foreshadowing a Regulation of the Cut and also some form of silviculture. The policy or Object with this class of Properties is rapidly undergoing changes in direction of real forestry. 3. Forests of Pulp and Paper Companies. Here large in- vestment stimulates effort to prolong the supply of timber, and the fact that smaller sizes can he used to good advantage and that a variety of species (especially of conifers) is used, facilitates this effort. Nevertheless these people have preferred thus far to lag behind : opportunity is of the best and should be evident to anyone. Here, intensive forestry, especially planting and clear cutting on lands that will grow timber rapidly, is indicated. 4. Miscellaneous Holdings of large tracts of forest such as the game preserves and parks in the Adirondacks and the East and South, holdings of Water Companies, etc., etc. Here the forest is secondary, it is kept for beauty, shelter of game, or for protection of the puritv of the water supply. Usually the object is to keep the forest with as little expense as possible, and generally these tracts are left, rather in the hands of a non-technical “Caretaker” than to a competent forester. The matter of income and expense and assured protection should decide these owners to prepare Working Plans and to practice rather intensive forestry. 5. Railway Companies in the United States have been and are now among the largest owners of forest. Most of their large hold- ings came to them as J,and Grants from United States Government to induce railway construction. A few of these companies have begun to employ foresters, most of them prefer to sell their hold- ings, usually to lumber companies. Jn many cases the holdings consist of inferior lands, practically waste lands, as in Pennsvlvania, etc., and of small bodies of lands held in connection with right of way and about stations. These Companies then: a. Hold for market large bodies of Virgin forest. Here. efforts, if any, are limited to protection and to disposals of land and timher, leasing of grazing lands, etc. 86 FOREST REGULATION b. Ilold waste lands; on some of these an effort at reforesta- tion has keen made. . c. Small patches of ground along their right of way and about stations. Qn these patches the effort is to keautifv, to please the traveling public. During the last ten years a few of these companies have begun to realize the danger of a shortage in railway ties, and are preparing to meet this by going into forestry, buying suitahle lands to provide stumpage and by proper care, raise new supplies. Tere is a field for the most intensive form of forestry, but as vet the object itself is still under debate, so that a real Plan in most cases does not yet exist. 6. State Forests. These vary from virgin forest such as parts of the Adirondack holdings, through all gradations of culled and cut over woods to the most desolate cut and burned-over sand plains of the Lake Region. Since the whole subject of state forestry has not yet hegun to be a real business enterprise, but is still matter of debate, with practically no recognition in the legislatures of the several states involved, there is neither policy nor appropriation, in fact not even good will, and the object of holding these forests is, therefore, an uncertain one, and can only be inferred from the efforts of those interested in the work itself and from the little work actually done. The small holdings in the New England States were set aside or acquired for the sake of saving the beauty or scenery, protect streams, and help as object lessons to the people. The state forests of New York ostensibly were for scenery and water preservation; in fact they would never have been bought and certainly never have been held, had it not been for the wealthy owners of summer homes in the mountains. The object here does not consider the forest a crop, nothing is cut, millions of feet an- nually, green and dead stuff, are allowed to go to waste. The work so far consists in a half-hearted protection and show place planting. there is no forestry, no lumbering, merely a holding of 114 million acres of wild woods in a state of Nature. Forestry here is still forbidden by law. Pennsylvania owns nearly a million acres of largely devastated mountain woods or Jands and is buving more: she educates her OBJECTS IN STATE FORESTS 87 own foresters at Mt. Alto; and proposes to practice forestry, Her laws are good and adequate. But in spite of the excellent efforts of those interested, and those directing the work, the State has not yet begun to treat the matter seriously in any particular bevond pernutting and encouraging the practice of forestry. The appropria- tions and the force of men is not 20% of what it should be, if these State lands are to ke converted into useful and valuable State Forests, and while the object is clearly stated in law, the legislature has not yet recognized the magnitude and importance of the enterprise. Michigan, for decades, had a fine opportunity of gathering up cut over lands, swamp lands. etc. For years she advertised six million acres as tax lands. [ut up to 113 these lands were sold at nominal prices. What there is left today as “State Forests” is primarily areas of poor sandy lands, cut- and burned-over re- peatedly, until they present far more a problem of waste land reforestation than the management of State Forests. In keeping with past policies, the object of holding these lands today is still uncertain. Wisconsin, like Michigan, continued in the same policies of land disposal until 1905. Since then certain areas have been definitely seé aside as State forests ; the policy of selling has been replaced by one of buying lands; forestry is attempted, laws are adequate and all that is lacking, is proper support and appropriation. These few cases suffice to show that with our State Forests, the object of holding and the policy of management of the lands set aside for State Forests is still in the formative stage. The subject of State Forestry is by far the most important one before the people of the United States. The value of State Forests is established in Europe; the object there, in most states, is: a. To assure a home supply of timber. b. To assure the continued best use of large areas of poor lands, of mountain country, sand plains, etc. c. To safeguard proper water distribution. d. ‘To maintain the beauty of the land. e. To derive an income from these properties for the good of the people. 88 FOREST REGULATION 7. National Forests. ‘The object as expressed in the original laws was to protect and preserve the forest and affect the water distribution in the mountains of the West. ‘loday the object has taken the form of a well defined policy closely patterned after that of State forests of Europe. This policy has been put into practice and the National Forest Service today is the only organization in the United States practicing Forestry in the most approved, up-to- date manner. It has gathered 90% and more of all needed forest information and has developed Working Plans, notably in the direc- tion of Forest Protection, unequalled anywhere. But the National Forests cover a large range of country, with great diversity of climate, topography, market, etc. In keeping, 'the objects of manage- ment vary for different forests. On the Angeles in Southern Cali- fornia where a chaparral is all that has been able to maintain itself as cover, the object is one of protection of this cover, though its value is only in water regulation and not in timber. On the Targhee where a high mountain country is covered with tracts of Lodge Pole and areas of grass lands, a proper protection and use of both of these is the object, and the forester becomes interested in Range problems as well as silviculture and logging. On the Snoqualmie protection and utilization of the great mass of standing timber and proper silviculture or method of cutting the old and growing a new crop of timber where old stands are removed is the object of man- agement and the forester here, like the forester of Germany, is first and last a timber farmer. C. CHOICE OF SPECIES. Right choice of crop is important on the farm, and ten times more so in the forest, where acorns planted today make a forest to be harvested in 200 years hence. a. In most cases, where we begin with wild woods, the species on the ground are kept. But even here there is often a choice as to which to favor, and which to suppress or eliminate. In the Spruce and hardwood forests of New England and the Adirondacks the Spruce is the most valuable tree and is favored ; the same is true of White and Norway Pine in the Lake Region. Longleaf, Loblolly and CHOICE OF SPECIES 89 Shortleaf of the South, Red Fir in Washington (West Side), Yel- low Pine in Idaho and Montana. b. In many cases site, climate, soi] and drainage dictate. A cold Tamarack Swamp leaves little choice, and the same is true of Jack Pine Sands; and Alpine districts in the Rockies and Pacific countries call for Spruce, Balsam and mountain Hemlock. Where the site is good, as on good hardwood lands in the Ohic Valley and South, the forester is largely directed by what is wanted, by owner and market, and may raise anything from a Catalpa fence post to White Oak saw and veneer timber. c. Where a mixed stand is desired, relative behavior of the trees asserts itself. Spruce and (ak mixtures have proven failures in Germany, and even Spruce and Reech needs watching wherever the Spruce feels at home. d. Where bare lands are to be reforested, the question often -arises as to the value of native as against foreign species or species from distant localities. Where no experiments are permissible the native tree deserves preference. But the prevalent fear of “exotics” is largely unfounded and based more on theory than practice. Red Fir in Germany has done well, so has White Pine, Black Lecust and Red Oak. Norway Spruce does well even in warm and dry situa- tions in Southern Michigan, and White Pine has made good groves on the plains. P e. Even under the old settled conditions of Central Europe this matter of Species is still a problem. receiving much attention and discussion. Some serious mistakes were made in the past. For instance, 20-40 years ago, Scotch Pine was planted extensively in parts of the Black Forest, where the heavy snows break down entire stands of these Pine poles, and give the present forester no end of trouble. Replacement of Beech by Spruce and other conifers is in progress on account of better incomes. Then also change from pure forests to mixed forests is being agitated. f. On large properties especially in mountain country this choice of species needs careful attention ; different parts of the forest require different species, and selection must conform to site and market, and provide not so much for the immediate but rather the distant future, and on all poorer lands the upkeep of site is fore- most. In the United States and Europe Market calls primarily for go FOREST REGULATION conifers and this may be expected to continue. (ccasionally a local market demands special materials, wagon stock, cooperage stuff, mining timber, pulp and acid wood, poles, piling, fence posts and even fuel; but such markets frequently Jack permanence to justify stocking large areas with the particular stuff desired. g. ‘lo keep up the fertility of the land much can be done in the selection of Species. Generally hardwoods are hetter soil pre- servers than conifers; tolerant kinds like leech and Maple are better than intolerant trees like Oak, Poplar, Birch, etc. (On the poor sands where only Pine makes a satisfactory crop, underplant- ing with Beech, etc., alone has been able to keep up fertility enough to enable the Pine to hold out to an age of 190 years and make acceptable sizes. It is primarily from this stand point that able authorities like Gaver insisted on the return to mixed forest in Germany. h. Over millions of acres of forest lands in the United States the combination of Site (land and climate) and market allow but little choice. Spruce will predominate in the cold Northeast; hard Pine in the Southern Pinery; pine in the Lake States; Yellow Pine and I.odge Pole in the Rockies, with White Pine and Larch in the Northern Rockies. Yellow Pine dominates the dry east side of Sierra and Cascades ; mixed Conifers the west side, and here Yellow Pine and Sugar Pine and Balsams in California; Red Fir, Hemlock, Balsam, Cedar and Spruce on West Side of Oregon and Washing- ton. High altitudes call for Spruce, Balsam, Alpine Hemlock and White Bark Pine, while our Tamarack Swamps call for ‘l'‘amarack, Cedar and Black Spruce. D. METHODS OF SILVICULTURE. a. Principal Methods of Silviculture. As distinguished by the great silviculturist Lorey may briefly be outlined as follows: 1. The Selection Method. “Plenter betrieb”, “Femelbetrieb”, Lorey. Composition: Pure or Mixed. SELECTION METILOD gI Age of trees on any one acre: old, middle age and young, i. e.. “many” or “all age” stands. Rotation, or age at which ripe timber is cut: Determined by size, 1, e., diameter limit. Cutting: Stand is cut over every ten or twenty years, i. e., the Period of Return is ten, or twenty years. The cut takes out large or ripe timber (harvest). It takes—-defective or poor timber (improvement cut). It takes out thinnings, and also provides for or stimulates re- production. The cut rarely takes over 4 of total volume of stand and puts woods in shape for next ten or twenty years. Reproduction: This is natural Reproduction from seed; in hardwoods also from sprouts (Basswood, etc.). Result: A Selection Forest whcre trees of all ages and sizes occupy the same fortv-acre lot, and furnish a great variety of sizes at any time from a small area. Advantage: Keeps a forest cover, protects young stuff against sun, wind and frost; protects soil against drying out and erosion. It gives a variety of sizes on a small area of Jand; and reproduces itself without expense. Disadvantages: Costs more to log: much injury to young stuff by logging; produces less timber; is irregular and difficult to control and therefore apt to be overcut or undercut. Applicability: To all species and sites. it merely follows nature's methods. For good business it should he restricted to tolerant species and especially mixed forest. In Use or Operation: Probably the oldest method, formerly much used abroad: todav 7% of all German forests are Selection Forests, and only about 2% of State Forest are in this form. In the United States this method is used in the woodlot and of late has been introduced in parts of National forests. It is the proper method in all rough mountain country, in ‘protective’ forest, and is well suited for a beginning in forestry in most of our large wild woods districts. It is nature’s method in our forests of hard- woods, and mixed stands, but is not the natural form everywhere, as is often claimed. In forests of intolerants, pure stands of hard g2 FOREST REGULATION Pines. Tamarack, etc., the even aged stands predominate and nature's method is a form of “clear-cutting” with seed trees. and “seeding from the side.” 2. Shelterwood Method. “Schirmschlagbetrieb” of Gaver and of Lorey and in part Lorey’s “Femelschlagbetrieb.” Composition: Pure and Mixed. Age of trees in any stand: Even Aged, i. e., trees are nearly cnough the same age, so that the small difference is not apparent in oiler stands. Rotation: a definite period. ripe timber is cut at some given age and not merely when of some particular size. Cutting, or Method of Procedure: For illustration: a. Cut out about one-third of stand, preferably largest trees, to open up entire stand and admit more light. Then wait for seed year. b. After seeding, take out another one-third of stand to make rocm and light for seedlings, and leave the last one-third of stand as an even shelter to protect seedlings against sun, wind, and frost and also to hinder a rapid development of weeds and brush. c. When Reproduction is well started and no longer in need of shelter, hut rather in need of light, the last one-third of the ripe timber is removed. In practice the method varies; it may use only one seed year, or several, it may take off the stand in two cuts or in six cuts: it may take only six vears (as in Pine) or forty vears as in Balsam and Beech in Laden: it may rely entirely on natural reproduction, or it may normally employ artificial help as in Beech forests of Denmark. Reproduction, normally is natural, and takes place before the old stand is entirely removed. Results: ()rdinarily an even aged stand where trees differ only 5-10 years in age: but in the “slow” forms the stand is not even aged and resembles the Selection Forest; trees vary from 30-40 years in age. Advantages: Combines the good qualities of Selection with those of all methods leading to an even age stand. Protects Site and reproduction: it enables careful control, assures better care in SHELTERWOOD METHOD 93 thinning, raises better and more timber, than the Selection forest; and it gives better utilization of site during the period of reproduc- tion than does the Clear Cutting system, where the land is not properly utilized for a period of several years. Disadvantages: Danger from blowdown of last part of old stand More costly logging, danger of costly delays when seeding fails: expensive artificial reproduction, where much is done to correct failures; with intolerant species is added great loss of repro- duction for lack of light, or else a cover of the land by weeds and brambles. Applicability: It is claimed by its advocates to apply to prac- tically all species. In actual practice in Germany it is generally a failure and has been abandoned except in Beech and Balsam. From this it is safe to say that it can well be employed in tolerant hard- woods and conifers. Spruce often fails by this method in pure forest, but works well if mixed with hardwoods. In Use: An old method developed in Beech forests. Today in use chiefly in Beech and Balsam, very little in Spruce, Pine and Qak. About 12% of all German Forests is Beech timber forest, and about 2% is Balsam, and these 14% are practically all handled under this system. Toth of these trees require shelter in the first few years. In United States practically unknown, and certainly never in regular practice. Well suited to mixed hardwoods and hardwoods with Spruce and Hemlock. Spruce alone cannot stand this method on account of blow down, unless the stand is reproduced, very slowly. and is not in exposed positions. 3. Clear Cutting with Natural Reproduction. Part of Lorey’s “Kahlschlagbetrieb” and of Gayer'’s “Saum- schlaghetrieb.” Including the “Seed Tree” methods introduced in United States. Composition: Practically always pure forest, with a little of other species “blown in” accidentally. Age of Stand: Generally even aged; depending on success of seeding. Rotation: .A definite period ; but timber must be old enough to seed abundantly. 94 FOREST REGULATION Cutting: Ripe timber is cut clear, normally in strips. Where west winds prevail, strips run North and South and work starts on the east side of any stand. Lest authorities prescribe narrow strips. not over 100 yards wide. Reproduction: ‘I'he strip of land cleared of timber is seeded from the side, i. e., we do not expect seedlings under the stand or trees, but away from the stand or trees, on open, cleared land. Result: .\n even age stand made up of kinds from which the seed is derived, generally one species, or pure stand. Advantage: Cheap logging, cheap reproduction, simple, even age stand. Disadvantage: lare land exposed to sun and wind covers with brambles and weeds. dries out and thus hinders reproduction. The seeding is rarely satisfactory, and if it must he helped artificially, is costly. Applicable: (nly used in timber with light seed, chiefly in pine and other conifers, also Aspen, DJirch, ete. Wath us in J,oh- loliv, Jack Pine, Shortleaf, also in Tamarack and Cedar Swamp, T.adge Pole, Red Tir, ete. In Use: Formerly this method was much used in North Ger- many in Pinery (on sands), and then modified in various ways (Coulissenschlage” of the Germans). ‘l'oday verv little is done with this method in Germany, and it is not recommended by best authorities (see Borggreve “Holzzucht”, p. 185, etc., and especially p. 200, and see also Reuss, Gaver, Weise, Ney of later authors). This method has been modified as follows: The lumberman either unable under the particular conditions, or unwilling to cut timber in small bodies, demanded that he be allowed to log off the land in large bodies, up to several thousand acres. To assure some reproduction of Pine (the usual species) and to give to young growth the benefit of plenty of light, and, in most cases, to appease the lumberman who was unwilling even to leave a reasonable portion of old timber, a few trees per acre were left as seed trees. as few as one tree per acre have been recommended and as little as 5% of ripe stuff was insisted upon and secured. Since these lone seed trees in most cases were left on relatively large areas, it was clearly a case of Clear Cutting with seed trees to seed from the side. In some cases (J.odgepole) lone trees promptly were thrown by wind CLEAR CUTLING 95 and the method was further modified. Groups of trees, blocks of an acre or more in size were left; then also the old method of “Coulissen” was revived in places. In United States all this is experimental as vet. in the last few vears there has been further development, a larger and larger number of trees are left, until this “seed tree method” is transforming into a form of open Selection method or a form near the “Zweihiebiger Hochwald", as described by Weise in his Waldbau. To call this Shelterwoods seems a misnomer, for it lacks the two principal elements: Shelter for seedlings and working to even age stand, the object being primarily to suit present condi- tions of market, and avoid large areas of clear-cut lands. This method of rapidly clearing the land of old timber and developing even aged stands appears to have been nature's way in most of our pineries, Tamarack swamps, and large parts of the forests of Red Fir. Unintentionally this method has been used in Loblolly to such an extent as to lead to the name of Old Field Pine. Large areas of burns have covered themselves with Jack Pine, Lodgepole, Red Fir, and Tamarack, indicating the suitability of this method in United States. 4. Clear Cutting with Artificial Reproduction. Composition: A mixed stand is feasible, but in practice the stand is pure. Age: Strictly even aged. Rotation: A definite age is adhered to. Cutting: he entire stand is cut clear. Reproduction: Ly sowing seed (even cones) or by planting young trees 2-5 vears old, raised in nurseries ; costs $5-$20 per acre, and normally succeeds perfectly. Result: An even age, usually pure stand. Advantage: T.and does not lie idle for years, waiting for nature to seed it: if five-vear transplants are used there is a gain of at least several years over seeding from the side, and ‘this may mean as much as $15-S20 per acre. J,ogging is cheap; in many localities in Germany the money saved by not having to skid logs and wood to the roadway (the common way) will suffice to plant the area 3-5 96 FOREST REGULATION times with good transplants. Produces largest return per acre in volume, quality and therefore in income, allows best care in thinning by a proper spacing at the start. Disadvantages: Leaves the land without a cover for several years (while trees small) and exposed to sun and wind. ‘This is of little consequence on all better lands, as the cover, when once established, stays for sixty and more years. The cost, even though not large, is not justified in very cold, rough mountain lands, remote and unprofitable under any condition ; but is justified under any ordinary conditions such as exist today in nearly all parts of eastern United States and Europe. It leads to pure forest. “his claim is not necessarily true, but in practice this condition has been established. How far this is injurious we are not certain as yet, except that large areas of one species suffer greatly when insect calamities arise. Applicability: German experience indicates that Pine, Spruce. Larch, Red Fir and Oak are hest raised by this method; Beech and Balsam do not thrive without shelter while young and are not raised on clear cut areas. Generally it is safe to say that this method succeeds with all but a few sensitive species which reyuire protection in the first few years. In actual Use: ‘his method has displaced all others from a large portion of the German, Swiss, etc., forests. It has proven simplest, safest and most profitable and all effort and preaching to induce the forester to return to a mixed forest with natural repro- duction has not had any appreciable effect. In United States this method has been started and is rapidly making progress, East and West alike. It is the only hope for at least one-half of our cut- and burned-over lands in the Great Lakes Region, Pennsylvania and the South. These four fundamental methods of the regular “timber forest” have been and are modified a great deal in ordinary practice. In the Selection Forest artificial reproduction is often emploved. the same is true of the Shelterwood and regularly in the method of Seeding from the Side. The Shelterwood Method, as stated, may drag out the process of reproduction over forty and more years and approach the Selection Method; or it may cut everything in two COPPTICH MRT HOD 97 culs within ten years, and approach Clear Cutting with a mixture of natural and artificial reproduction. Then also any method may be employed on a large area, or a small one; on areas in the shape of strips or circles, (groups, spots and patches) scattered over the forest. [jut whether the area on which we cut clear is a regular forty-acre tract, or a number of small, say three-acre tracts, scattered over a few forty acres, has nothing to do with the method itself; it is still Clear Cutting with natural or artificial reproduction as the case may be. Unfortunately a great deal of coining of names has been done in this connection so that Mayr in his Waldtau enumerates sixty-four different methods of treatment where in reality only about half a dozen methods exist and receive slightly different application to suit particular condi- tions. That the many names coined for real, or only supposed, variations merely lead to confusion and not to clearness and better understanding has already been demonstrated in the United States as well as abroad. 5. The Coppice Method. German “Niederwald.” Composition: Usually hardwoods, pure and mixed. In United States so far chiefly Oak and Chestnut; (Red Wood in California) I,ocust, Catalpa, etc. Age: Even aged. Rotation: 15-40 years. Cutting: Cut clear, with axe, and cut slanting stump and close to the ground. Reproduction: From sprouts, at times may need a little help hy planting. Result: Coppice woods, even age stands, generally small tim- l:er, cordwood and poles, even tie size: also tan bark. Advantage: Cheap logging, simple to handle: regular, little subject to windfall, etc. Small capital, inexpensive. Disadvantage: Needs fair land; mild climate; can use only hardwoods (except Redwood) ; raises only small stuff not demanded by big market. Small income has resulted in gradual degeneration of French coppice. 98 FOREST REGULATION Applicable: On good land, mild climate, with home or local market for small stuff of hardwoods. In Use: In about 7% of all German Forests: only 1% of all state forests in Germany; extensively used in France and the Mediterranean countries. In United States woodlots: formerly, in Maryland, Pennsvlvania, etc., in regular wav for iron works, now largely abandoned. ‘The large forests of United States and North Europe are generally conifers, on rather poor lands and little suited to coppice. 6. The Standard Coppice. “ALittlewald” of the Germans. Composition: Pure or mixed; the Coppice is of hardwoods. and usually also the “standards”, but this is not necessarily so. Age of any Stand: Coppice is even aged. The Standards vary in age by multiples of the rotation of the Coppice. If the rotation of the Coppice is twenty years, and the Coppice growth on any one acre is fifteen years old, then the Standards are: 15 vears, 35 years, 55 years, 75 years, etc., old. ‘his regularitv in actual practice rarely exists. Rotation: Coppice with short rotation, 15-30. Standards with long rotation, 69-200. Reproduction: Coppice, and artificial, usually planting of large plants for standards. Results: An uneven stand, often resembling, in practice, a wild woods, old and young stuff on every acre. Raises cheap cop- pice stuff as well as large, but usually limby timber. Advantages: Like Coppice, except that large stuff is also produced. Disadvantages: ll those of Coppice, except that it produces also larger stuff, but. in addition, is very complex and difficult to handle. T.ittle control, little order, a regular “gardener’s” job. In Use: Formerly much used in all good hardwood districts of Germany and France. Rapidly giving way to simpler methods. usually Shelterwood. CHOICE OF METHOD 99 In United States never systematically practiced; some of the woodlots present conditions and appearance of a regular Standard Coppice. Outside of the woodlot there is no place for this method in United States. b. What Method to Use. 1. In the beginning stages of forestry in our wildwoods it is rarely possible to introduce at once the method best suited to Species and Site. and it will be necessary for many years to come, to com- promise between that which should be done and that which can be done under given conditions. Nevertheless, it is well at this point to warn against too great stress on given conditions, for the most important of these, transportation and market, are changing so rapidly that it is a great mistake to contract and otherwise plan for long periods ahead on the assumption that things remain as they are. This is being realized of late. and most of our timber contracts no longer run for indefinite terms on conditions rigidly fixed at the outset. 2. In large areas or properties of Wildwoods we commonly meet the foliowing three conditions affecting the choice of Silvicul- tural Method: a. There is no net growth; decay and growth balance. ‘his is not always true; it is more true in our Hardwoods and Hemlock of the Lake Region than in the Pinery; it is more true in a large area of Southern Pine than in the Pineries of the Rockies, etc. But it is always near enough true to urge immediate removal of the old, defective stands, the stands “going back”, etc. The first demand then is to cut the property over for old and defective timber to start or to increase net growth on the land. b. Logging in the wildwoods where all roads and other im- provements must be made, and generally also, must be paid for out of the proceeds of the first cut, requires that large contiguous areas may be logged together. But good forestry in Clear Cutting as well as in Shelterwood system demands small cutting areas. There is but one compromise and this is the Selection Method where enough is taker to warrant logging and enough is left to assure safety and welfare of the forest. 100 FOREST REGULATION c. Our forests still lack proper protection and will fer a long time to come. For this reason large areas of reproduction (1000 acres and more) of Pine and other conifers in solid bodies are very unsafe affairs and should be avoided. We may expect some serious calamities in this direction. iNeeping in mind these three points, it would seem clear that in most of our large forest properties the aim should be in the first cutting over: To Leave a Forest, to let reproduction come in slowly, under protection and in interrupted areas, groups and patches and so avoid especially the great fire risks. 3. In districts where stumpage is now valuable, market and transportation good, and growth satisfactory, there is no good reason why more intensive work should not be done. In many areas of this kind it will be far better to clean off the old stand entirely and restock by planting, where hest species and proper spacing can be assured. Generally it may be said that wherever stumpage is $10.00 and over and where inferior material can be removed at cost or at some profit, and also where growth per acre and vear may be set at 75 cu. ft. of wood, it will now pay to cut clear and plant. These conditions exist today in a large part of the eastern United States and are rapidly extending everywhere. c. Illustrations from Different Forest Regions. The following statements are not intended as directions but rather as illustrations of what is under consideration. In every larget region conditions vary and the most intensive as well as the most extensive systems are indicated in practically every forested state in the Union. 1. ‘he Woodlot of the Farm in the eastern half of the United States. Here the land is usually fair, even good, it is valuable, a large return should therefore be demanded. Labor is ample, market of the best. usually the farm home takes a large part of all that grows, and requires this right along. Work normally starts with a mismanaged. hadly over-cut tract, often. grazed, with little repro- duction and poor growth. .\ first cutting over in several years time removes old and defective trees. This should be fotlowed by plant- ing or seeding if necessary to start a satisfactory stand. .\fter that CILOICE 1N SHU VICULTURE IOI the Selection method or Standard Coppice will furnish good results in all of our hardwoods. In Conifers cut clear hy strips and replant at once; mix in few hardwoods to better the soil. Ordinary coppice works well in hardwoods of the East and South but in the States west of the Alleghanys tends to poor dried out scrubwoods. except in moist situations. 2. Spruce Forests of the Northeast. These are mountain woods varying from pure Spruce to hardwoods with a mere sprink- ling of Spruce. On lower slopes and in valleys. not farmed. (or farmed formerly and now abandoned) a milder climate produces forests of hardwood, Hemlock and White Pine. The sites vary from good valley and bench lands and lower slopes with a fair depth of soil, to steep and high slopes with thin rocky land. The climate is. cold, winters long. snowv, frosts late, summers cool and short: precipitation ample, specially dry years (fire danger) occur at inter- vals of 10-20 vears and have led to bad forest fires. In keeping with cold climate, growth is generally slow (except on good valley lands), small timber logged today is generally over 150 years old; cut per acre generally less than 10 M. ft.; size of timber rarely over 20” and over 100 ft. But the ample humidity of climate of this region makes reproduction easy and assured: not only White Pine, but also Spruce readily seed up ahandoned pasture lands. On higher mountains there is a scrubby forest, which should never be cleared. but held as protective cover. Market along all railways, good, proximity to Boston and New York should make them of the best. But so far transportation facilities have been deficient, railway construction being costly, only Spruce and Pine could be logged and driven down the various streams, while hardwoods in many places have remained practically valueless. his is rapidly changing. Log- ging is costly in keeping with small timber, light cut, and bad topography. ‘The Selection method is best suited to all upper slopes and rough lands and should come often enough (every 15-20 years) to take out timber in small quantities, and leave a fairly dense cover on account of windfall. Spruce should be favored, but hardwoods should not be entirely cut out for reason of soil and beauty. On kench lands, etc., Clear Cutting and planting of White Pine (and Norway Spruce?) has already proven a success. 102 FOREST REGUL ATION 3. Appalachian Mountain Region from l’ennsylvania South. Low mountain region. mild climate, at lower elevations: great variety of topography and soils: valleys settled to farms; rain fall over 40” and steep slopes Jead to much injury from erosion where forest is cut clear, this injury is especially bad in the deep soil districts from Virginia southward. Forests of hardwoods, generally mixed with hard Pine, and farther up with Hemlock: at higher altitudes and in north half of district, White Pine on north slopes of West Virginia, etc., Spruce forest. Lumbering old, and forests largely cut clear in north half, in south half lumbering now at its best, clear cutting the rule. Logging expensive especially in south half ; no snow, steep ground; much rocky land, long ridges ; requires railway: and these are costly. Market excellent, plenty of indus- tries; large cities near, and matter chiefly one of transportation. Growth and reproduction in keeping with climate, generally fair to good, except on very poor soils. Rapid development of this region, excellent sites and proximity to great cities call for intensive methods as far as soil and topography permit. Wherever there is great danger from erosion, and also on the poor, rocky sites the Selection method alone is justified; Coppice in small areas serves to hold soil and furnishes good timber (Chestnut and Oak). On easy slopes, benches, etc.. with sufficient soil, the system should be suited to species, and for conifers Clear Cutting and artificial repro- duction, doing away with all delay and uncertainties is justified unless insects should prove too serious a menace. In this case mixed forest in Selection method or Shelterwood is most efficient. 4. Southern Pinery, Great sandy Plains with rich narrow river hottoms and extensive swamps; warm climate, (cotton belt) heavy rainfall, plenty of rain all through the long growing season. Growth rapid, reproduction easy and safe Forest homogeneous pure pine woods. Market and transportation good now: proximity to sea and to large eastern cities, and ease of railway construction promise to muke market as good as exists in any forest region. Considerable agricultural development. Logging simple and cheap. Market and Site call for intensive methods. Pine site generally now worth over $20.00 per acre to raise timker on a 3% basis. The sandy soils call for Vine in pure forest. even age stands, and justify Clear Cutting CHOICE OF METLIONS 103 with artificial reproduction, and short Rotations. Vlenty of rain makes natural seeding in open Shelterwood stands possible in Long- leaf as well as Shortleaf and Loblolly, and clear cutting with seed- ing from side will prokably succeed better in Loblolly and Shortleaf than with any other species and in any other region in the United States. River bottoms and swamps should be developed agriculturally. s. Pinery of the Lake Region. .\ large district of level country, with numerous drivable streams, excellent transportation facilities by Great Lakes and many railways. Region covered with glacial drift, soils deep, generally sand. or loams and gravels. Nor- way and White Pine on sands (Jack Pine on the poorest), Hard- woods and Hemlock on loams and better sands of Wisconsin and eastward. Swamps and lakes scattered over entire region; swamps stocked with Tamarack, some Cedar and Spruce. Winters cold and snowy, spring dry, growing season short, severe spring frosts; specially dry seasons every 8-15 vears have led to great forest fires. Growth and reproduction fair; an 18’7 White Pine produced in 100 years; clear cut lands dry out, “brush up" and restock with difficulty ; Hemlock does not reproduce at all under these conditions. Market good now, $10-$20 on stump for Pine, growing better rapidly : log- _ging efficient and cheap. Market and Sites call for intensive methods. Except in swamps and specially poor sands or rocky-thin- soil lands Clear Cutting with artificial reproduction should restore a truly valuable stand. Jn Hardwoods the Selection system may be used as a starter, should take out the large and poor trees and leave at least half the stand on the ground. On moist sites Shelterwood is practical in Maple and Beech woods, but will not make the returns which can be secured by a clear cut with artificial reproduction in which Spruce and White Pine replace the greater part of the hard- woods. Tamarack and Cedar in the swamps restock readily by seeding from the side, but in larger Cedar stands a Selection method is preferable as it prevents rank growth of swamp “brush.” Jack Pine with Clear Cutting and seeding from sides, in narrow strips should he kept until these lands have recovered from the effects of burning, and after that Norway Pine (also Scotch Pine) should replace Jack Pine: 104 YOREST REGULATION 6. Western Yellow Pine Districts. ‘hese Western Pineries occupy the dry, warm. lower slopes of the Rockies, the east side of Sierras and Cascades and the dryer slopes of the west side of the ranges from Middle Oregon South. ‘Topography and soil vary within wide limits; the soil, being dry, is generally fertile and it is the warmth and dryness of climate (and soil) which give these sites to Pine. Hard-baking “adobe” soils in Arizona: coarse granite sands and gravels on the east side and limestone soils on the west side of the Ijlack Hills and pumice sands in parts of the Cascades indicate variety in this direction. Forest varies from open, park- like stands of pure pine woods to rather dense and brushy mixed stands of Yellow Pine and Red Fir, with Balsam and Larch in Jdaho, or Yellow Pine, Sugar Pine, Balsam and Cedar in California. Tendency, as in all hard pines, to even age stands. Reproduction varies chiefly with moisture conditions and is precarious in most parts of Arizona and New Mexico, easy on the granite in the Black Hills, much more difficult on the limestone, etc. An 18” tree requires over 150 years in the drier parts of district (-\rizona). only about 100 years in the moister portions (parts of Oregon and California). Topography varies from perfectly level and easy rolling plateau country in Arizona, South Dakota to steepest moun- tain lands. Market just developing, transportation to long distance markets (Chicago, Kansas City, etc.) costly. Logging very variable, easy on plateau, difficult in mountains where it calls for chutes or slides, etc.; high cost of labor enters heavily. Protection against fire a serious problem. summers generally dry ; specially dry seasons recur at intervals 10-20 years: great fires 1902, 1910, et. DBarkbeetle a serious menace to the “all old” stands. So far several methods have been tried. The lumberman has generally cut clear, taking all he could use. ‘The Government has tried Clear Cutting with seed trees or seeding from side; and various modifications of this method in the direction of ordinary Selection method. Generally this latter method is best: a. To avoid exposure of large areas to sun and wind and thereby rendering difficult, if not impossible, the natural reproduc- tion desired. b. To avoid large contiguous bodies of voung growth until some later period when fire protection is ample. CHOICE IN IMNERY 105 c. ‘To enable present development where the market is unable to use everything and also to work over small, detached areas. d. To encourage early removal of large masses of defective and dying stuff. Since dryness of climate is everywhere the serious difficulty in Western Yellow Pine forests, introduction and care of Balsam. Cedar, Red Fir and Hardwoods which tend to give more density to forest and thereby better protection from drying winds is advisable in spite of the lesser value of these species as timber. Where artificial reproduction is necessary to re-stock larger areas of clear cut lands it is best done by planting of good stock, spaced not less than ten feet, and planted with sufficient care to assure success. Rodents are a serious obstacle to natural and arti- ficial reproduction of Western Yellow Pine. 7. Lodge Pole Pinery. These forests are of importance in the ‘higher slopes of the Rockies from Colorado north, and also in the northern Cascades, as well as out-lying mountains like the Big Horns. The Sites are inferior; a cold climate and short growing season make slow growth. It requires generally over 100 years to make a 12” tree, and 150 years to grow a crop of tie timber. The sites varv in topography and soil; large areas are plateau country with ample depth and quality of soil; the altitude assures reasonable moisture conditions and encourages reproduction. ‘This takes place readily on clear cut and even burned-over lands, less readily within the: stands. Exceptionally drv seasons and prevalence of electric storms have led to great conflagrations in lodgepole; large areas are bare, and generally stands of pine are even aged. At the lower limits Lodgepole merges into Yellow Pine, and then is often mixed with Red Fir; above, it grades into the Alpine forests of Spruce in the Rockies, or Balsam, Hemlock and White Bark Pine in the Pacific Ranges. The market for Lodgepole is generally a local one; it is, there- fore, developed only in a few places located near large mining enter- prises, Montana, Colorado, Utah, or convenient to railways (tie timber) as in the Big Horns and along the U. P. Ry. in Wyoming and N. P. Ry. in Montana. Logging here is regular mountain work, as a rule, calls for chutes, flumes and other special devices 106 FOREST REGULATION Slow growth, size and quality of timber, remote location, little market, costly logging, difficulties of labor situation in such remote districts, then also the importance of this Pinery as “protection forest”, all call for Selection method, at least in the beginning work. Leave a forest. After this pinery is sufficiently developed as to Utilization and Protection, so that small bodies of timber may be removed econom- ically, the Clear Cutting system may be employed, as better suited to this decidedly intolerant species. So far Clear Cutting with seed trees in various modifications has been employed. Of late this method has keen replaced, at least in part, by a Selection method ‘with more or less compromise to enable profitable utilization. Artificial re-stocking of these lands is hindered especially by rodents, and has not been found an easy matter. If it were not for these animals, an old time sowing of cones should succeed on Lodgepole burns. 8. Hemlock and Balsam Forest on the West Slopes of the Cas- cades, notably in Washington. Large mountain slopes, with fairly deep coarse soils, heavy precipitation: deep snowfall: remarkable snow melts leading to destructive floods. Good growth, ready reproduction and tolerant species all combine to make these idea! stands for valuable Selection forest. Danger from erosion alone calls for a method which keeps a constant cover on these slopes. -\bundant waterpower and forest make a good combination: and proximity to ocean will soon make market conditions such that.the Lest care of the forest will be justified. 9. Forest of Red Fir in Washington and Oregon. Large bodies of giant timber, “all old”, often broken stands where Red Fir, Hemlock, Spruce, Cedar and Lalsam occur in all forms of mixture as to species, age, and condition; also large areas of young stands from 10-1e0 vears on former burns. Sites vary as to top- ography and soil, from level to the roughest. from deep soil to rock masses, but over the entire area a mild humid climate assures rapid growth and excellent reproduction. On good ground a growth more than twice that observed in Michigan forests is nothing un- common. ‘The real home of Red Fir, which grows to great size (200 ft.) and age (400 vears) and produces yields of over 100 M. ft. CHOICE OF METHOD 107 per acre and is exceptionally free from insects and disease, and at the same time makes material most in demand by the market. Choice of Silvicultural method is dominated by preference for this species. Since [lemlock is far more tolerant and readily takes possession of the ground even under a good stand of Red Fir, Selection or Shelterwood are not well suited here, unless Hemlock is wanted as mixture. Wath a prospect of excellent market within twenty-five years proximity to sea. excellent growth and easy reproduction, there is no reason why Clear Cutting with planting should not be recommended. The feregoing sketches will indicate the view point and some of the conditions which enter into the matter of choice of Silvicul- tural Method to be emploved in any given case. It is clear that no general lines can be laid down which may be applied without modi- fication, and every case needs special study. In this connection it may ke stated that large areas of cut-over lands, usually Eurned over repeatedly and deteriorated through soil wash, exposure to stin and wind, and now occupied by useless brush, should be planted without delay. The enterprise is a gigantic one; it is peculiar in that it does not lend itself readily to ordinary private enterprise. A man of small means cannot wait fifty years for the crop; the men of large means do not want to wait. The local town- ship and even the local county is too poor to do this woik. So it remains for the State and Nation. And rarticularly to the State should fall this task, and all lands not well suited to agriculture should be bought up and promptly converted into State Forests by planting. Such an enterprise would be most profitable for anv State to undertake, it would assure local supplies of timber, stimu- late wood-working industries, regulate water flow. help the appear- ance of the district and would make millions of acres produce the only crop which is an assured success upon these lands. ‘The attitude of indifference in this connection will cost vast sums in the future. To get some measure of what is needed here it may be said that a State like Pennsylvania could well own 20% of its land area in State Forest, and that it should spend at least $1.09 per acre in care of this and before long (in the life of a state) would have a net income of $3.00 per acre from these forests. 108 FOREST REGULATION E. ROTATION. In Central Europe timber is cut at an age varying from twelve years in Coppice to 200 yeirs in Oak for timber. Where regular timber (saw timber, etc.) is raised in Germany it is generally cut at the age of: Pine and Spruce 80-109 years, (G0-Ro0 vears in private forests). balsam over JOO years. Beech 100-120 vears. Oak 150-200 years. Rotation has been shortened during the past 100 vears es- pecially in Conifers. Reason for this lies chiefly in market and in the introduction of rational methods of forest valuation. German market for saw timber today prefers timber 107-15” d. b. h. to larger or smaller, and the hest sizes are 11/’-13/7, requiring about 70-90 vears in dense forest. The matter of Rotation is of great importance in Germany today in spite of the old settled conditions of forest and market. It forms one of the important topics in forestry literature, and the Bavarian government has recently established a special commission to ascertain proper Rotation for ditferent forests species and sites. In the United States this matter is rapidly coming to the fore- ground. The preliminary regulation for National forests requires establishment of Rotation. Recent studies of White Pine, Loblolly, etc., attempt to work out the age when it is most profitable to cut the crops of timber to be established.* The Kinds of Rotation usually distinguished are: a. Technical Rotation. Which allows the timber to grow to a certain size, needed for a particular use, such as pulp wood, fence posts, railway ties, tele- phone poles and piling, saw timber, ete. This condition of size dominates our present market and through this the utilization of timber. *See Bull. 17 (new series) 1914. U. S. Dept. Agri. Sterrett: “Forest Management of Loblolly Pine.” ROTATION IN FORESTRY 109 1. In Loblolly or in Lodge Pole enterprises for hewn railway ties the diameters preferred are 12”, 13”, and 14”. Jf this is the only use for which the timber is grown, and we get as many ties from the 14” tree as from the 17”, it is obviously useless to allow the tree to grow to 16” and waste time and use of land for perhaps twenty vears (Lodge Pole) or more. This case, especially in slow growing Lodge Pole, illustrates the importance of careful determin- ation of Rotation. Ifa stand of Todgepole produces practically as many satisfactory ties at 150 vears as at 180 years, to leave this material the extra thirty years would be a loss which, in large operations, would run into a considerable sum. ©n the other hand. if 150 vears are required to produce tie timber, then it is useless to discuss shorter Rotations unless it is reasonably certain that other uses may be expected to change the market. This also illustrates the uncertainty in this determination of Rotation, especially in new countries where market is rapidly chang- ing its requirements and prices. 2. Generally the upper limit is less rigidly fixed, larger timber means a greater number of uses, but the lower limit is fixed. In spite of all the changes of the past 100 years, a few funda- mental facts remain valid today. ‘The consideration of a few principal uses may illustrate this: a. Fuel wood, though used in enormous quantities must be cheap and have local market; it competes with coal, is almost excluded from many districts, does not pay for long distance trans- portation (unless by water); can be supplied from thinnings, ete. Even fifty years ago it was a factor in Forest Regulation, called for a Rotation of maximum volume, and was regularly transported especially by water to larger towns of Europe. Today it has generally disappeared from consideration of the rotation. b. Pulp wood requires reasonable proximity of, usually, large and costly mills; it favors conifers and of these the Spruce. So far it pays well, competes with lumber in purchase of stumpage. The use of other species is growing, and like fuel wood, pulp wood may largely be cut from thinnings in the future. So far Pulp wood has not attained an importance to control Rotations, but has affected the practice of thinning, and indirectly it is leading in the direction of shorter rotations. In the United 110 FOREST REGULATION States pulpwood may soon call for special forests with a practice and Rotation calculated to produce largest volume: of well cleaned material. .\ sixty year Rotation for planted Spruce is indicated in the Northeast. With exhaustion of cheap cooperage and veneer material and with increase of cheap power by stream development, pulp board will increase in importance and be able to utilize cheap woods and refuse-materials in large quantities. c. Railway ties, telephone poles, piling, wagon stock, and other similar timber requiring sizes over 10” d. b. h. compete with saw timber for stumpage except that species like Cvpress, Cedar, Hard- wceods can be used, not commonly desired for lumber in these smaller sizes. Generally 107d. b. h. inside bark is the lower limit and whatever time is required to produce this size will remain the minimum rotation for this important class of materials. ‘whe fact that rough, limby and crooked material can ke used here will affect the rotation Lut little, for an adequate yield per acre demands a fair cover of trees in which light is fully utilized and growth therefore slower than seen in shade trees and park stands. ‘lies cut in the United States today vary widely in age. For Lodgepole over 150 years; same for White Cedar ( Michigan, etc.) : over sixty years for Oak, only 30-40 for Loblolly. d. Ordinary Saw timber prefers conifers to hardwoods, at present in ratio of three to one; demands fairly clean and straight material, prefers even grained and slow grown stuff and does not go below 10” d. b. h. mside bark. The few special cases (box boards with us to 8”) do not alter this materially. Europe has probably reached the smallest practicable limit in its present market demands. Smaller sizes mean increased waste in sawing, poorer product, and they also mean waste in the forest by taking stuff at a period of rapid growth. If this is true then, the time to grow a tree 12” d. b. h. outside hark is the minimum Rotation in saw timber, and this size must be produced in good form, fairly clean of limbs, and preferably with an even and fine grain. Saw timber cut in the United States today gives but little information on this point. Generally it is larger and much older than is needed. The giant stuff of Redwood and Red Fir, Sitka Spruce and Cedar on Coast is generally over 250 years old, much of it over 300; the same is true of Cypress in the South; CHOICE OF ROTATION III Sugar Vine, Western Yellow Pine, Hemlock and Iongleaf as cut for lumber today are generally over 200 years old; White Pine, Spruce, Lodgepole and Cedar, also Oak. Yellow Poplar, Maple and Beech, over 150 years old, and the rest of saw matcrial generally over 100 years. Using 12” d. b. h. as minimum size, measurements thus far made would indicate for ordinary sites a technical Rotation: Of forty years and less (down to twenty-five years) for Cotton- wood, Red Gum, Eucalyptus, Red Wood from sprout, also for Maple, Elm and other timber on good soils like river bottoms, etc. Of 40-Go vears for: _ White Ash, Red Oak, Chestnut, Elm, Basswood, Cuban and Loblolly Pine, and the following lacific Coast trees, Red Fir, Hem- lock, Spruce. Sugar and Western Yellow Pine. Of 60-80 vears for: Norway Pine, Eastern and Western White Pine, Longleaf and Shortleaf Pines of the South, Cypress. Red Fir of the Rockies, Hickory. and Yellow Poplar. Of 80-100 years for: White Oaks and Western Lalsams and Cedars in the mountains. ()f 100-120 years for: Maple, Beech, Yellow Birch of Great Iakes Region and East, Eastern Hemlock. Of 120-150 years for: Red Spruce, Tamarack, Lodge Pole and Engelman Spruce of the Rockies. These figures are mere suggestions, and would be modified within wide limits by the site covered, as well as methods used in care of the forest, planting, thinning, etc. e. Furniture lumber and Tight Cooperage call for hardwoods in larger sizes with fully matured heart wood where stch decides desirable color and other qualities. Here 18” d. b. h. may be set as minimum. Jn central Europe, White Oak is grown to an age of 160-200 vears and even older. It is doubtful if Rotations of over 150 years will he provided for in the future, since combination of good soil and climate and relatively small vield tend to make the raising of this class of timber unprofitable. In addition rapid exten- sion of commerce with the tropics may make it unnecessary to provide for much of this kind of timber in the future. TI2 FOREST REGULATION ‘b. Rotation for Largest Volume or Yield of wood per acre and year. This usually refers to “cordwood and better” (about 3” thick and over), but in many localities abroad, includes even faggot material. As stated before, this Rotation was entirely proper when certain forests had to supply a large population with fuel, so that fuel had to be shipped into the districts. Today such a Rotation is the exception, but may again come into use with development of the Pulp industry and better facilities for marketing and shipping materials demanded in the slack barrel, box board and other industries. Rotation for largest volume in Germany and for fair to good site (site II) is about as follows: Pin ..c¢acsewvterdegiae 060 years SPICES sg ceed dace oa Lal tert go-109 years Beech and Balsam....... 110-120 years This fits in very nicely with the technical Rotation for these species. c. Rotation of Largest Yearly Income. The following figures will illustrate what is meant here: One acre of Spruce on Site II in Germany may present the following conditions: Age Yield Expenses Net Income. Se. or of final and during the |————] Average| Rental Val. Stand. thinnings. Yr years, Total. per year of land. Years. $ per acre. $peracre, |} Per acre.

After CHOICK OF. ROTATION 113 this the total net income goes to $1967 at 120 vears but the average per year hegins to decrease. The table also indicates that the owner receives highest average rental per acre from his land if he cuts it at eighty years or thirty years before highest average yearly income occurs, In this calculation for Greatest Net Income per acre and year, the assumption is that we normally have a forest and not merely bare land; that this forest is reasonably regular so that a yearly income is produced. If then Rotation is eighty years, for instance, we could take an eighty-acre sample of this forest and get from this eighty acres each year: (ne acre of ripe timber. Several acres of thinnings (these are made about every ten years in good forests abroad) and we would have as expenses : One acre to plant and Kighty acres to protect, pay taxes on, etc. Putting this in a formula we have: Yr— Ta-+ Tb, etc. —C—re r Average Net Income per acre = where Yr== Stumpage Value or net Yield of one acre of ripe tim- ber, here eighty vears old. Ta= Value of Thinnings made when the stand is a years old, ete. C == Cost of planting one acre. re == Value of taxes, protection, administration, etc., i. e., of yearly expenses for r acres. Using the above table we have: = : . . 121284 Average Net Income per acre on eighty year rotation ———— d. Rotation for Highest Rent per Acre of Land. This is also called “Financial Rotation” and may also be called “Rotation for highest Rate of Interest on Capital.” The assumption here is that bare land is the real capital and that by using it to raise timber this land is made to pay a rental, and the object is, in using this Rotation, to secure best net rental per acre. The calculation, then. starts out with an acre of bare land and inquires into the 114 FOREST REGULATION amount of material and values we can produce from this acre and the cost of doing it. The calculation usually employed is based on the following general formula of the present value of a series of rentals coming at regular intervals, and continuing indefinitely as does rent from land. R os Rental Value or Income Value of the Land where T.op"— 1 R is the rental, i. e., the net income which can be produced every forty, sixty, etc., years, i. e., every Rotation. p is the rate of interest. n is the number of years to grow the crop, here then the age at which the stand is cut, i. e., the Rotation. To illustrate: Tf cut at sixty years, and the total net income at sixty years will be $500; and if 1.03°° == 5.89, the interest rate being 3%, the calculation then is 500/5.89 — 1 == 509/4.89 = $102 approximately. According to calculation, this acre of land brings enough rental to make it worth about $102 if used for the purpose of growing the special kind of timber and cutting it at the age of sixty years, pro- viding we are satisfied with 3% on the money spent in planting and all other expenses." A great deal of controversy has taken place over the last two forms of Rotation, and German foresters are still largely divided into two camps on this question. The tendency is toward a full recog- nition of the value of financial Rotation with a compromise justifv- ing a larger income with a smaller interest rate or net rental on the *The proper formula to employ in this calculation is the formula for Se, or the Income Value, or Expectation Value of the Soil. This formula in its usual form reads: Yr + Ta (t.opt-a) + Tb (1.0pt-b) — C (s0pr) e= —-E L.opt —1 where Se is Expectation Valuc or Income Value of the Soil, or land per acre.

FINANCIAL ROTATION TI5 land. An illustration from the management of a farm will explain the attitude of those opposed to a rigid adherence to this financial Rotation: A does little work, has poor buildings, little stock. small investment. He also has a poor crop, but this small crop forms a large per cent of interest on his investment. B employs plenty of help, has good buildings, lots of live stock, large investment. He has a large crop tut this large crop is but a small per cent on his investment. According to census figures a farm in Alabama pays a higher rate of interest on investment than that of Tllinois, but the latter has easily twice as much income per acre per year. Generally B with his well tended farm is considered the right farmer and not A. The new Bavarian Instructions expressly state that rotation should be so chosen that demands of the home markets are best supplied, and a fair income is secured. ‘The latest Prussian Instructions do not discuss this point, evi- dently a refusal to commit the State to the principle of a financial Rotation, for which there has been a great deal of clamor. e. Physical Rotation. Besides the foregoing four kinds of Rotations authors generally mention a fifth one, Physical Rotation. This is little explained as a rule. Judeich says it is a Rotation where timber is cut at a time when easiest reproduced, bears plenty of seed, or sprouts well (in coppice), or else it is natural Rotation where timber is allowed to go as Jong as it will live naturally. Neither of these conceptions are very helpful. More useful is a consideration of the relation of Rotation and up-keep of fertility of the land. This is important especially in forests of Pine and other intolerant species stocked on poor sandy Jands. Here the stand opens up after it gets to be 50-80 years old, and allows wind and sun to injure the soil by destruction of humus and by drying. Even on fair soils as in Oak woods such soil-deterioration takes place and must he met either by shortening Rotation or by under- planting, or other silvicultural means. Generally, then, Rotation is suited to market, to rate of growth, and therefore to Site. Species, and treatment. But in all forests 116 FOREST REGULATION many stands never grow as is expeced and hoped, and must ke cut younger or left to grow older than is prescribed by the Rotation. For these and other reasons some authors have suggested that Rota- tion is an unimportant conception, and that it is useless to try to decide on a definite Rotation. Even among foresters of experience the opinion is not rare that Rotation is set by guess or feeling. ‘The fallacy of all this is evident from the foregoing. The table of net incomes pictures faithfully what actually occurs in the forest regard- less of the figures used, and if it makes land worth 25% more by cutting at eighty vears it is certainly poor policy to let the stuff go to an age of 110 vears and take a smaller per cent interest besides much longer risk. ‘That :uropean Governments consider Rotation of great importance has been stated. In addition it may be said that Regulation of any forest demands establishment of a definite Rota- tion, just as much as any big enterprise requires definite estimates. Organization of large railway and other transportation systems is usually Lased, of- necessity, on assumptions which are probable but never exact or certain. Experience of the last 100 years in Europe proves conclusively that growth in the forest is sufficiently regular to be estimated to any degree of accuracy here demanded. but it also indicates that there is a limit to this degree of accuracy and that there is no need of hair-splitting, but that a range of 5-10 years must be conceded even in Rotations of 60-100 years. Generally, longer Rotations demand larger capital in form of timber, involve more risk for any one stand, tend to reduce rate of interest on the capital, but make for larger income per year and produce a material of better price and a much larger market, and usually are better for maintaining the site. f. Natural Rotation. In wild woods is the average life of the Species. In a pure stand of intolerant species stich as Lodge Pole, Longleaf, Loblolly or Norway Pine, Tamarack, etc., the old timber, even though stands open up considerably, prevents reproduction effectively. When once the stand breaks it is readily hurt hy storm and the great number of defective, dying and dead trees also invite insect trouble and fire. Accordingly these pure stands of hard pine and other intolerants are NATURAL ROTATION 117 apt to break down fast, and leave the field practically free for young growth which now gets plenty of light to start. This new stand is practically even aged, trees develop and grow old together and the story of decline and replacement by a new stand repeats itself. With these species the pure even age stand is rather rule than exception in our wild woods. In mixed stands of hardwoods the case is entirely different: Normally the site (soil, etc.) is much better; the several species differ in tolerance, growth, reproduction and they vary in longevity and resistance to injury. Here the stand does not go down together (unless it is a case of windfall), is constantly reproducing, every opening is filled, it rarely forms even aged stands over large areas and even when it does (after accidental destruction) reproduction sets in long before the old stand really breaks. We have the Selec- tion Method practiced by nature. It is reasonable to assume that on any one township of hardwoods in the Ohio Valley in virgin state the total amount of timber remained fairly constant; growth and decay balanced, old, middle aged and young stuff, i. e., the Age Classes were properly represented; rotation varied for different species, but it was always the average life of the species. In this way these virgin, mixed woods presented a certain regularity com- parable to that attempted by the forester. On the other hand, a property stocked with pure stands of even aged pine, etc., may or may not be regular. In fact there are areas of Lodge Pole Pine of Over 100,000 acres in which certain age classes are almost wanting, a fact which needs consideration in planning for a steady supply of timber and income. g. Choice of Rotation in United States. Generally, Rotation should be chosen no longer than is neces- sary to produce desired material, a good income from the land, with full assurance that the fertilitv of the land is not impaired. On good sites, with good growth and high stumpage calculation of net rental on a reasonable interest rate should never be omitted. In such calculation the following facts should have due con- sideration : 1. Sizes demanded by the Market are growing smaller, but will probably not go beyond present European Jimits. 118 FOREST REGULATION 2. .\ good practice of thinning can reduce Rotation by many years. 3. Planting of strong plants, 4-5 vears old and proper spacing can i) many places save ten years on Rotation. In our wild woods and where a beginning is made by the selec- tion method, the natural Rotation is apt to be misleading. In certain Lodge Pole forests a technical Rotation is indicated by the time it takes to grow a railway tie; say 150 years. If this forest is to be regulated, as to yearly cut, by Hundeshagen (or Von Mantel’s modi- fication of this) it becomes necessarv to set a definite Rotation. In deciding this Rotation, the temptation is to use the age of “mature stuff’’ and employ natural Rotation as criterion, largely on assump- tion that a shorter Rotation would furnish a much smaller volume. If the cut is 12 M. ft. per acre and mature stuff largely 200-250 years ald, the assumption usually is that it takes about 200 years to produce this volume of 12 M. ft. This is an error, and it will be found. in most cases, that volume (not only in tie timber) is fully as great. say, at 150 years, as at any time later, and that, therefore, this Rotation of 150 years not only furnishes the proper size, but fully as large a volume.* * That a stand of timber does not add volume indefinitely, or even to great age is self evident and is well shown by European Tables. And no amount of care in thinning, etc., is able to change materially this fundamental fact. In wild woods pure even age stands reach the point of maximum volume apparently much earlier than in forests recciving proper care. In Oak, site I (as per Schwappach) yield of stuff 3” and better of the “main stand” is, at 140 years about 7000 cubic feet, and at the age of 2co years only 8sco, making only 1500 in 60 years ‘in spite of all care. In Scotch Pine yield per acre does not materially increase after 120 years, even on good sites and with best of care. Schwappach’s tables give for the “main stand” at 100 years about 6000 cubic fect and for 120, 6300, and only 6400 at 142. These figures are for fully stocked stands and must. in this respect, be regarded the exception, for it is here where Silviculture finds its hardest problem, to keep the stand intact. A century of storm, hail, ice, insect and disease affects the forester's efforts, and German forestry today has not yet succeeded to hold its stands better than about 85-90% stocked, even up to too years, and longer Rotations would certainly reduce these percents rapidly. In wild woods dense stands of the sapling and pole age introduce great and lasting struggles, ordinary and normal competition helps to injure the forest, and there is no agency to correct this mischief. Results are evident, the fully stocked “forty” in wild woods is rare, particularly in pure stands of in- tolerants. REGCLATION OF CUT TI9Q F. REGULATION OF THE CUT IN AMOUNT AND IN LOCATION. German: “Ertragsregelung” including the “Hiebsordnung.” I. General Considerations. Since Forest Regulation aims to make a forest property into a regular business with yearly income proportional to investment, and since timber ordinarily requires fifty and more years to grow, cut- ting of the timber must be adapted or regulated to fit into the general plan. 1. The farmer harvests all that grows on an acre of land each year, the forester must let growth on any one acre accumulate for fifty and more years. The farmer harvests growth from all his lands each vear, and his vearly harvest is exactly what grows in that -particular year. The forester, to have a vearly cut and income, must regulate his business, and in any case he does not cut what grew in that particular vear, but an amount equivalent to the vear’s growth. in fact he cuts what grew during the last fifty or one hundred vears on a part of his land. In this way the forester’s crops average up and yearly income is not fluctuating to such a degree as it is on the farm. 2. ‘To be able to cut a crop of ripe or eighty-year old timber each year, the forester of a 20,000 acre property must have areas of old, middle age and young timber at all times. In this particular case he would really need 250 acres of 80 year old, 250 acres of 79 year old, etc., all the way to 250 acres of one year old stuff. This perfect regularity is not possible; fire, storm, snow, frost, insects and disease, all help to disturb regularity even if it were possible to establish. 3. In practice the forester is satisfied if he can get an approxi- mation to this, such that he has, in the above case, 5000 acres of stuff between Go and 8o years, 5000 acres 40-60 vears, etc.; 1. e., that each twenty year Age Class, have about an equal area of land. To bring about this regularity of Age Classes in the forest is one of the chief objccts of regulating the cut. 4. This regularity, when once accomplished, not only assures a yearly ctt and income, but it does more. :\ssuming proper care 120 FOREST REGULATION in Silviculture, this regularity provides the following fundamentals of good forest business. a. Yearly cut of about equal volume. b. Yearly cut of about the same age, size and quality of timber, and hence a yearly income of about the same amount. c. Growth and income is secured on a capital no larger than is necessary, and therefore this regularity assures the largest per cent of interest on the capital. d. Best growth under given conditions of site, species and rotation. e. Greatest degree of safety from fire and other dangers, since the forest is never made up entirely of young, or of old stuff. In short the forest is in a properly regulated or “normal” con- dition. s. From the ahove it follows that if the forester “over cuts”, i. e., cuts much more than the proper area or amount of timber, he cuts into the “capital” and must make up by saving, later on. If he “undercuts”, i. e., leaves a lot of ripe stuff on the ground, he reduces growth and income, for old stuff does not grow as fast as voung timber. For any given place or forest there is a certain Rotation which is better than a longer or shorter one, and once this is decided upon, Regulation of the cut is bound by it. The lumberman normally overcuts, and thereby cuts capital and growth; the farmer in his woodlot often overcuts in one place and undercuts in another; Bavarian State forests for years have been undercut, and income kept unnecessarily low. Overcutting a forest tends to devastation and neglect. As soon as yearly income fails or becomes too small, the owner loses interest, he “retrenches”, i. e., he neglects, and the mischief grows at geometric ratio. (vercut also hurts market either by over-production or by failure of regular supply. Experience in the United States as well as abroad is the same on this point. Regulation of the cut, then, should prevent overcut as well as undercut in the forest. 6. Keeping in mind the changes in market, bad seasons, fire, insects and other enemies, amd then also mistakes of the forester which disturb regularity of reproduction. growth and development of the many stands of timber in a forest, it is evident that this reeu- DISTRIBUTION OF CUT 121 lation of the cut is never more than a good approximation, and alsu that it is never finished but needs revision from time to time in order that regulation fit the changed conditions of the forest due to growth, cut and injury. 7. Where Clear Cutting, or Shelterwood systems are used, and also where, as in Western Yellow Pine and Lodge Pole, the Selec- tion method and clear cutting are combined in various ways, in fact wherever an area of land is cleared and the old stand replaced by a voung, even aged (or approximately even aged) stand, there enters a new factor in this matter of regulation: Order, Direction and Distribution of the Cut, (“Hiebsord- nung, Hiebsfolge”) determining Distribution of Age Classes, i. e., Distribution of old and young stands in the forest. 8. This proper distribution of stands of young stuff, middle age and old timher is demanded by Silviculture and by Protection and on large properties also by local market. To illustrate: Assume ‘a forest of 20,000 acres, one solid block of level lands, all Spruce, Rotation eighty years. Also that it is possible to cut 250 acres each vear and replant. If this cutting were done in strips running north and south, there would be a strip of 250 acres each year, and in twenty years there would be a solid body of 5000 acres all covered with young stands from 1-20 vears old, most of them dense brush, highly inflamable, and completely ruined if fire ever got in. Danger from insects and fungi need not be mentioned. Again suppose an attempt were made to cut the stands from West to East. A solid line, six miles long, of large timber would be left without protection and, in case of Spruce, surely be thrown by the wind, the mischief going right ahead of cutting, making miles perhaps, during a specially bad season. Suppose this same area were entirely cut over and cutting ready to begin along the East line. If now it should happen that certain tracts in the middle of this area were injured by fire, or msects and had to be cut at once, such cutting would make a break in the cover and set the mischief of wind fall going. But these accidents and many others must be met in every property and during every rotation. Again in mountain country every valley has its own peculiari- ties as to wind and storm, and these need to be considered, the aim being alwavs to “cut against the wind”, and also to avoid having to 122 FOREST REGUL, VEION move cut timber through areas recently restocked with young growth. Ther also it has long heen found that it is much easier to repro- duce a stand of timber, whether by natural or artificial reproduction, if the area to be covered is small and surrounded by forest. Since this is largely a matter of drying winds, it is most important in dry and windy situations and districts (lake Region, Rocky Mountains, etc.). This matter has become a principle in Silviculture. Good Silviculture calls for small cutting areas, and these properly re- stocked before cut of timber proceeds. 9. To bring this about, one of the principal efforts in Regula- tion is to direct the cut of the forest in such sequence or order as to enable the forester to have: a. Small Cutting reas. b.’ Many separate tracts at any one time where ripe timber can be removed; i. e., many points of attack. c. No large area covered with timber of one age and in such condition that he can not cut any portion without serious danger to the rest, or surrounding timber. d. ‘fo have the cut proceed against the wind and so avoid danger from windfall. e. Avoid large areas of young stands (especially important in conifers on account of fire). 10. To enable the forester to plan and cut timber in proper order and direction, to enable him to get at every stand whenever it is in need of cutting and reproduction, is fundamental in all methods where the forest cover is entirely removed at times. 11, Cutting Series (Germ. Hiebszug). ‘To do this, however, the forest needs a proper division beyond mere land-division into lots described before. It is necessary to divide the forest into a number of small independent parts, each separated from its neigh- bors by a Eroad line and each surrounded by a satisfactory forest korder. These independent parts are the Cutting Series. 12. Centuries ago when there was either Coppice, Standard Coppice or Selection forest there was no demand for this division into Cutting Series, but with development, especially of the Clear Cut and plant method, it hecame a silvicultural necessity. CUTTING SERIES 123 At first, especially on level ground and easy slopes, these Cut- ting Series were made large, often of five and more lots, and there was devised by Reuss a regular form of arrangement for them. The older Cutting Series were so large that they required the greater part of, or the entire Rotation to cut over.

Division into Lots and Cutting Series, showing the old or “Normal” form of Distribution of old and young stands in the Forest. Lots I-53 in the upper tier, form one cutting series for a 100 year rotation, the plan being to cut one lot every 20 years. The cutting series is surrounded by a broader: line (30 feet) so that a forest border can form, and thus it becomes quite independent of the surrounding woods. Schematic, and conditions as they should be at begin of rotation, in this case, once every 100 years. In the diagram, Figs. 3 and 4, illustrating the old and also the Reuss pattern the Cutting Series in Fig. 3 has five compartments. If the timber is worked on a I00-year Rotation, and has five Age Classes. a cut is made every ten years to give reproduction a chance. Then the forester cuts 14 of No. 5, and plants; in ten years he cuts second half of No. 5, etc. In this way the Cutting Series is just 124 FOREST REGULATION covered during one Rotation, and every Cutting Series on the prop- erty is planned to be cut over in this same sequence and at the same rate. These old time Cutting Series proved too large and have teen generally abandoned. Today a Cutting Series is commonly made up of two lots. often of a single lot, and is cut over in ten or twenty years, and normally in much less than the full Rotation. see Ss Wind Cul sae FOV MN Oye et) oe eee Wee LP eo ge He Ficure 4. Reuss’ Pattern of Division and Distribution of old and young Stands. This separates the oldest, and the youngest better than is done in Figure 3. In any case the danger line is the line between the oldest and youngest stands. Schematic and conditions as they may be found at any time. Only two lots in each Cutting Series; this is optional. Mayr in his Waldbau recommends going a step further and making the Sub-Lot or even a smaller area the Cutting Series to enable q better use of the land; his idea being that each stand should he pure, i. e., of one species, but that the stands should be small, and different kinds of these small stands mixed to produce a mixed forest of pure stands. CUTTING SERIES 725 13. The advantage of breaking up the forest into a large num- ber of independent parts is evident from the following case: <\rea of forest: 20,000 acres.

The dan- gerous winds come down the Valleys. In lot 1 and also in No. 2 a storm- point is produced by the position of the Valley on W. side. This also makes it desirable to cut down-valley in lower part of No. 4, but not in No. 3. Arrows point in the direction in which to cut. 126 FOREST REGULATION Cutting Series of two lots each .”. 125, of 160 acres each. Yearly cut (by area): 250 acres. Cut during one “period” or 20 years: 5000 acres or about 31 Cutting Series. Cutting area 40 acres, with 5-year rest between cuts at any one place. Having over thirty different Cutting Series or independent parts, all of them with ripe or sufficiently ripe timber, ready to cut, the forester has ample choice, he can cut at thirty different points, and if at any one point reproduction is not succeeding, if insects are destroying his plantations in any place, and it is necessary to wait, he is in position to do so. In short this division into Cutting Series gives many points of attack, it makes the entire enterprise ‘flexible’, enables the forester to cut any stand when it is necessary, without hurting the rest of the timber, and enables him to give each stand the care it needs. In our beginnings in the United States it may seem too early to speak of such refinement of methods as the Cutting Series indicates. But it is almost certain that the next fifty years will demonstrate the dangers and losses which are sure to come with extensive unbroken areas of pure growing stands of pine, etc. The Cutting Series is a silvicultural necessity, and its development is neither difficult nor costly. 14. It is evident, from the foregoing that the Cutting Series is not always a permanent division right from the start, but, like the Sub-I,ot, or stand division, it may for many years be in a temporary condition of development. As to its size, the present tendency is toward making each Lot a Cutting Series and getting the greatest possible use out of the system of lines maintained, as well as the smallest possible Cutting Series.* 15. Working Section. German: ‘‘etriebs Klasse”. Where a forest property is of ordinary size, (25000 acres or less) and is made up of one type of timber, all pine, all mixed hardwoods, etc. Regulation of the cut usually applies to the entire property. *See Martin, “Zeitschrift fiir Forst und Jagdwesen,” 1905, p. &6, on Forest Division in Austria, Also. Wagner, “Raumliche Ordnung im Walde,” which treats entirely of this silvicultural division of the forest. WORKING SECTIONS 127 Where the property is made up of two or more, radically dif- ferent types of woods so that each of these types requires special treatment, then the forest is divided into two or more Working Sec- tions. The following illustrates this: rea: 20,000 acres. Location: Michigan Pinery district. ‘Tvpes: Hardwood and Hemlock........ 35% Or 7,000 acres Pinery proper ..............0.. 50% or 10,000 acres Tamarack and Cedar Swamp....15% or 3,000 acres Hardwoods Hardwoods ? Ficure 6. Township of Typical Lake Region Pinery Lands with three types of lands and three permanent types of forest; Pinery lands with pure and mixed stands of Pine; Hardwood and Hemlock forests on slightly heavier soils; and swamp lands stocked with Tamarack, Cedar, mixed with Spruce, Pine, and Hardwoods in better drained spots. These three types call for different species, silvicultural methods, and rotation and therefore demand three separate Plans, each type forming one Working Section. From the diagram, Fig. 6, it is apparent that the swamp forests are in several pieces of irregular shape, following drainage lines. The plan of Silviculture here proposes to treat Pine by the Clear Cut and plant method, Hardwoods as Selection forest, and swamp 128 FOREST REGULATION timber by cutting clear in strips and depending on natural repro- duction. In this way the three types of woods, on three very different kinds of land or sites, may be expected to differ always. Regulation of the cut is made much simpler, the plan much clearer, by making a separate plan of Regulation for each of these three types, and treating each type as a separate Working Section, just as if it were a separate property. In larger properties, and in properties made up of several separate tracts, miles apart and especially in mountain districts where different watersheds have different local or general markets, this matter of distance, separation and market, alone justifies divi- sion of the forest into Working Sections. A forest like the Lig Horn, over sixty miles long and twenty miles wide, supplies settle- ments many miles apart. In this case each settlement or local market requires a steady supply of timber and the forests of each of the larger stream basins may well be made into an independent Work- ing Section, with its own plan of Regulation and its own series of Age Classes, or voung and old stands and its own continuous supply of timber. From the above it is clear that a Working Section is a part ofa forest property having its own Plan of Regulation of the cut, series of Age Classes, and sustained yearly cut. Up to sixty years ago the great importance of local market as compared with distant, large city markets, was so great that each Working Section, and certainly each Forester’s District (“Revier” of the Germans) was expected to furnish strictly the same amount of timber, year by year. With extension of railways, local market lost in importance and large forests depend almost entirely on distant markets. In such cases an equal cut each year from each forest or Working Section is no longer so necessary, and there is considerable agitation abroad to do away entirely with this requirement of a sus- tained yearly cut even for each district or “Revier’ While, perhaps, permissible in the case of State or National forests and for large forest properties, yet its advisability is doubtful. The State forest which will be cut over regardless of future regularity of supply and left for twenty-five years without any timber cut and income, will not fare well in allotment of appropriations. RUGULARITY IN WILD WOODS 129 16. Where Regulation of the cut and orderly work begins in wild woods the following is accomplished : a. Decay is replaced by harvest or cut of ripe timber, and decay is therefore reduced to an insignificant amount, the unavoidable defect. b. Natural Rotation is reduced by many years, and changed to a business rotation. c. The amount of timber, the “Growing Stock” is usually re- duced. In many cases this is not true, for the growing stock in wild woods is not always large, due to defective and useless stuff and unstocked ground. d. The condition of equilibrium where growth and decay bal- ance changes to a condition of net growth. e. This net growth is improved by good silviculture which eliminates weeds, and keeps all lands stocked with most productive species. f. Fertility of the land is usually reduced, at least in time. In the United States fires in the pineries and mountains have done this to a serious degree. 17. Natural Regularity in Wild Woods. In wild woods, too, there is a certain degree of regularity, comparable to that sought by the forester. This is greater in mixed hardwoods than in pure conifers, as pointed out under “rotation”, especially those of intoler- ants like hard pine, Tamarack, etc. In mixed hardwoods in Southern Michigan it is probable that even on a single township of virgin forest the following conditions were maintained : a. Rotation equal to average life of the trees of each species, hence varies with composition and is never uniform for entire stand. b. Age classes generally well mixed on every forty; all age classes represented; all-old and even-aged stands of any size the exception. c. Growth only fairly good, and not good in keeping with the excellent sites; too much over-mature, crippled, defective, spread- crown stuff; then also a great deal of poor stuff and brush, (Blue Beech, Mornbeam, etc.) 130 FOREST REGULATION d. Growth offset by decay, the forest in a condition of equili- brium (just as in a well regulated condition). For this reason no net growth on the entire area. e. Growing stock quite large but not in keeping with the long (natural) rotation and excellent site. From measurements made it is clear that on areas of 300 acres and more the growing stock up to 200 years old was frequently much less than could be produced by healthy stands half that age. In forests of Lodge Pole, Western Yellow Pine, Norway Pine, ‘Tamarack, Longleaf Pine, where even aged stands prevail the condi- tions on a property, even of 50,000 acres do not “even up”, and we may and commonly do have: a. Rotation, quite uniform, and equal to average life of the tree, over 200 years. b. .Age classes on separate areas, not generally mixed, with some classes wanting. These, according to studies thus far made most commonly the middle sizes or large poles, (mere accident). Classes prevailing are mature or old stands. so much so that the statement has been made that the forest is made up of all old, i. e., even age mature stands, which, of course is not true for large properties. c. Growth over large areas often very small, due to dry, poor or cold sites, to prevalence of old broken stands and large per cent of hare ground. d. Growth and decay do not balance even on large tracts; in some cases decay over balances growth, while in others considerable net growth exists, and only a complete study determines the true status. e. Growing stock rarely large, commonly smaller than a pro- perly stocked and regulated forest would have at half the natural rotation. In forests of tolerants, such as Spruce. Hemlock and Balsam the conditions resemble more those stated for mixed hardwoods. But in keeping with the simple composition (one species often) the condition is intermediate. In all cases some reproduction sets in as soon as the stand begins to open or break, but quite commonly it leads to rather even aged, more than many-aged stands and in this respect approaches the condition of pure stands of pine. MMTILODS OF REGULATION 131 On most of the large pronertics several types of forest are represented. In the Great Lakes Region pinery there is rarely an entire township without some swamp forests and hardwoods or hardwood and pine mixed stands. Naturally each of these presents its own regularities of rotation, age classes, etc., and needs to be considered separately. II. Methods of Regulation of the Cut. A. General Consideration and Classification. 1. Plan of Regulation of the Cut involves two distinct tasks: a. Regulation for Regularity of Age Classes, and with this of Regularity in Amount of timber cut, 1. e., for a forest in which there is always a proper amount of young, middle age and old timber, in which, therefore, the different age classes, 0-20, 20-40, 40-Go, etc., year old stuff occupy about equal (or equivalent) areas of land, and supply a yearly cut of about the same Volume and Value. b. Regulation for Proper Distribution of Age Classes in the Forest (Hiebsordnung, of the German} i. e., for a forest in which stands of young stuff, poles, and older timber are not in large, un- wieldly bodies, made up of stuff of about the same age, but are in small stands regularly mixed, judiciously arranged to enable good Silviculture, effective Protection, and convenient Utilization. Jn the Selection forest mixture of Age classes is by smallest possible areas and represents really the greatest refinement in this direction. 2. Where forestry is once well under wav and where even age stands are to he grown on large properties, the second of these tasks, proper Distribution of stands is more important, and practically reduces the first, Regulation for Age Classes to a very simple operation. Regulation for a Proper Distribution of ge Classes depends on a suitable division of the forest into permanent Lots and into Cut- ting Series, and once the forest is properly divided and the Cutting Series developed, further Regulation of the Cut is largely assured. But this Regulation for Proper Distribution of Age Classes must he worked out for each forest right on the ground. The book and 132 FOREST REGULATION school can do little more than give a few principles, to guide in the work. It needs study of the forest, and years of observation and experience with species and site. For this reason the subject is dealt with briefly in the textbooks on Regulation, is almost lost sight of in some of them, in spite of the fact that it is just in this phase of the work where knowledge, experience and capacity are most needed. 3. Regulation for Regularity in Age Classes as stated above. works for sustained yearly cut of about equal amount and value, for best growth possible under given conditions of Site, Species, Silvi- culture and Rotation, and for a Growing Stock or amount of grow- ing timber on the Jand, no greater than is necessary to secure growth and income. It prevents Overcut and Undercut. It is particularly at this last point, the prevention of Overcut and Undercut that this Regulation begins on new or wild woods property because the first question asked, when there is once market for the timber, is: how much can we cut on this property without over- cutting ? 4. From the nature of a forest property it is clear that there are really only two ways of regulating the cut of timber: by Area or by Volume. If a forester has a property of 20,000 acres and works on a 100 year rotation, he can: a. Cut an Area of 200 acres per year and cover the property every 100 years; or he can b. Cut an Amount or Volume of tinthber which he believes or estimates to be equal to the amount which grows on his property, say 15,c00 cords. 5. If faithfully persisted in and carefully revised every ten or twenty vears, and if Silviculture and Protection are attended to, either of the two plans will regulate this forest. If he regulates by Volume, he must begin somewhere and cut a sufficient area to get the Volume estimated to be right, and he must do this year after year. After going over the property once or twice, he will almost certainly drift into a method, cutting over each year the area he cut during one year on his former round; in other words, a Regulation hy Volume is practically certain to change into a Regulation by Area, which as Cotta correctly foresaw, over a century ago, is the final in all Forest Regulation. REGULATION OF CUT 133 6. In practice the two Methods have often been combined, and in Classification of these Methods three forms are usually spoken of : Regulation by Area, by Volume, and by Combination of Area and Volume. ‘To be exact, however, Regulation in these Combined cases is a Regulation by Area with Volume as a check. In the above case the forester may decide on cutting over about 200 acres and also decide that he does not want to cut over 15,000 cords. If then he cuts his 15,000 cords and only needs 180 acres to do so he violates his area-regulation, and if it keeps up, he will also violate his rota- tion. Nevertheless this volume check enables him to offer the market equal quantities of material, and this advantage is sufficiently great, so that this volume check is commonly applied abroad though fundamentally an Area Regulation is maintained. 7. Methods of Regulating the Cut in amount, by Area or by Volume, all tend toward Regularity of Age classes, for it is only by establishing this regularity of Age Classes that any method of Regulation can hope to secure the benefits of properly regulated or “normal” forest as set forth above. But none of these methods in themselves attend to the second great task of Regulation, mentioned before, Proper Distribution of Age Classes, or stands of different age, in the forest. In the above example, the forester may cut one piece of 200 acres after another, so that at the end of twenty years he would have 4000 acres of young stuff in a solid body, from the standpoint of protection a most un- desirable condition, in Pine and similar timber. 8. Being simply based on a known Area of land or an esti- mated Volume and a Rotation agreed upon, or some kind of com- bination of these, the matter of Regulation of the Cut in Area or Volume lends itself to mathematical treatment quite in the abstract. Fer this reason a goodly number of such methods have been devised and published, and new ones are still springing up almost every year, in spite of the fact that only a very few ever really entered the practice and that after a century of discussion and trial, greatest authorities and greatest owners of forest, like the States of Germany have practically all returned to one simple method, the Limited Area Allotment, with a Volume check, the “Judeich’s Method” of 134 FOREST REGULATION Schlich, the “Bestands wirtschaft™ or ‘Alters Klassenmethode” of Judeich himself.* 4. The following Classification of Methods of Regulation of the Cut “Ertragsbestimmung™ or “Ertragsregelung”, is taken from Judeich. a. Area Methods (“Flachenmethoden”). 1. Fixed Yearly Cut (Schlich) ; “Schlageintheilung”. 2. :\rea Allotment; (“Flaichenfachwerk”). b. Volume Methods (‘Massenmethoden’). 1. Volume -\llotment (“Massenfachwerk”). 2. Methods based on Normal Growing Stock (“Normalvor- raths methoden”). c. Combined Methods (“Kombinierte Methoden’”). 1. Area Allotment with Volume Check ‘Kombiniertes Fach- werk” 2. Combination of Area Allotment with Methods based on Normal Growing Stock. 3. Age Class Methods, i. e., Methods working primarily for Regularity of Age Classes.* “.Altersklassenmethoden”™ or * Besiands- wirtschaft”. As a fourth form he mentions Wageners Regulation by Cuts of Equal Value, which apparently is mentioned more as a curiosity than a thing of value in practice. NM B. The Regulated or Normal Forest. Study of a model forest, a perfectly regulated forest, fully stocked and all stands in satisfactory condition, 1. e., a “Normal Forest’, is of help in understanding not only the methods, but also the real objects of Regulation of the Cut. * See also the recent Texthooks of Judeich, Martin, Guttenberg, Stoetzer, Weise; also Official Instructions of Bavaria, 1912; Borgman’s “Die Ent- wickelung d. Forsteinrichtungswesens—Eberswalde—Biesenthal”; and Schil- ling’s Article in “Zeitschrift fiir Forst und Jagdwesen,” 1913, October. * It is singular that Judeich persisted in the above Classification of this most important of all Mcthods. A glance at his problems and explanations shows that it is an Area Regulation with volume merely as a check. Stoetzer (sce p. 213 of his book) recognized this and calls it a “limited Area Allot- ment”, “beschriinktes Flichenfachwerk. Sce also Schilling in “Zeitschrift fiir Forst und Jagdwesen.” 1913, October. But also Wagner's “Grund- lagen, ete ~ NORMAL FOREST 135 1. Let a given forest have an area of 12,000 acres, all of the sane quality of land, site II, and be stocked with Pine, managed on a rotation of sixty years. Being perfectly regular in age classes, there are on this forest in the fall of the year and before the yearly cut is made, 209 acres of sixty-vear old timber, 200 acres of fifty- nine-year old, etc., down to 200 acres of plantations one season old. 2. If we take one acre sample of each of these stands we get a miniature model forest of sixtv acres with one acre sixty years old, one acre 59 years old, ete. This small model or sample forest can be regarded as a separate normal forest and what is true of this sample applics also to the 12,009 acre forest. This sixty acre model or sample is represented by a diagram in Fig. 7; each strip represents the volume of wood on one acre of land. The strip at the right represents one acre of sixty years old timher now ready to cut or the Yield of one acre, i. e., Yr., say 5600 cubic ft. 3. If the silvicultural plan is to cut clear and plant at the age of sixty and thin each stand every six years, then the work on this Normal forest of sixty acres is as follows: Fach vear there is: (ne acre cut clear. (ne acre of six-year old, one acre twelve vears old, ete., in all nine acres are thinned. One acre is planted. Sixty acres are cared for and have taxes paid on them. 4. Leaving out of consideration growth and cut of stuff re- moved in thinnings, the following is true: a. Cut each year is 5600 cubic ft., i. e., the stuff on one acre of ripe, or sixtv-year old timber. b. Growth on the sixty acres is 5600 cubic ft. per year or the amount cut each year. The growth being sixty acres, and the cut on one acre we do not cut the growth of the year, but an amount equal to the growth. c. Growing Stock on sixty acres is indicated by the triangle at least closely enough for our purpose here. This triangle has an area: 60 & 5600/2 = Yr X 1/2. Growing Stock 168,coo cubic feet. 136 FOREST REGULATION d. Growth on this sixty-acre sample of normal forest during one rotation of sixty years is 60 K 5600 = 336000 cubic feet, or twice the amount of Growing Stock found on the sixty acres at any one time. In other words, the Growing Stock is replaced every thirty years, or in general in r/2 years. e. Growing Stock is reduced each winter by the yearly cut. of 5600 cubic feet, and is replenished the following summer by the season's growth. : FeAl all Crowina ; afl G 5 Towing tock WE Pc AANA Vol. /acre bO acres «VY acres ‘Yr 70 y.

In this forest of 60 acres: r is the Rotation or 6o years, Yr is the ripe timber 60 years old on one acre, (5600 cu. ft. in our example) G is the Growing stock on 60 acres, varying in age from I to 60 years. This G does not change, i. e, it is the same every year. Each strip represents the volume of timber or wood of one acre; and the volume is here assumed to vary directly as the age. The cut of ripe timber in each year is Yr equal to the growth on 60 acres. The cut in 60 years is 60 X Yr (The parallelogram in fgure ) or twice the growing stock found at any one time. Thinnings are neglected in this consideration. NORMAL FOREST 137 f. The growth of 5600 cubic feet is the growth of ripe timber; it is made by sixty acres of growing trees and each acre makes or is assumed to make 5600/60 = 93.3 cubic feet, the average yearly growth of ripe timber on one acre. This distinction of growth of “ripe timber” is made because the growth of the material taken in thinnings is omitted in this consideration. g. Yearly cut of 5600 cubic feet from this sixty-acre forest forms a definite portion of the growing stock which may be ex- pressed in per cent: Cut as percent of Growing Stock == 5600 & 100/168000 = 3.3%, 1. e., each year 3.3% of the Growing Stock is cut, and we can also say that the average growth of this growing timber is 3.3% in Volume. ‘Ihis conception was used by Hundeshagen in his Method of Regulation. h. The Cut of 5600 expressed as a fraction of the Growing stock is: Cut ==Growing Stock /1% the vears in rotation = 2G/r= 168000/30 == 5600, which is a useful conception applied in Von Mantel’s Modification of Hundeshagen’s Method of Regulation. i. A glance at the Diagram Fig. 7 shows that if all of the sixty acres were stocked with forty-year old timber, the growth would be greater than it now is (forty-year old stuff being in the age of most rapid growth), and the amount of growing stock would be greater than in the regulated forest but it would not be possible to have a yearly cut, until the forest were again regulated to its present condition of Age Classes. Again the sixty acres might have all timber eighty or 100 years old and so a very large amount of growing stock and capital and yet have a small amount of growth. and be unable to furnish a vearly cut without considerable sacrifice. This merely illustrates that it is only in the Regulated forest that Growth, Cut and Capital are properly balanced to supply best yearly cut and income. 5. Perfect regularity in matter of Age Classes, growth and Growing Stock is probably never attained in any forest. On the other hand it is quite surprising how perfect the regularity of Age Classes is coming to be on larger State forest properties of Europe and how readily and steadily this regularity maintains and perfects itself under well planned management. 138 FOREST REGULATION Fig. 8 illustrates the Regularity of Age Classes on Working Section No. II of the Sihlwald of the City of Zurich, a 780-acre tract of forest on rather steep mountain slopes and frequently injured by heavy snows, and therefore difficult to keep in well regulated condition. ae, ae een _ [way -L le onditions Z 70-100 ene Seckin J [gate 0-70").

Regulation then simply divides this forty acres into twenty equal parts or twenty cutting areas, of two acres each, and plans to cut one of these every vear. o\gl|el|7{,e);r} 4,3 [2yz 20|19\ 18\77\ 6\ 15) (8) AS) AAV Ficvre 9. Diagram illustrating the Fixed Yearly Cut in Coppice. The 40-acre lot is divided into 20 equal or equivalent pieces, and one piece is cut each year, preventing all over-cutting and assuring proper age class condi- tions and maintenance of the adopted rotation. In actual practice these areas may be monumented to-save the trouble of re-survey, and assure greater accuracy. Tf this plan is followed, the small, coppice woods will be regu- lated in twenty vears, and this regulation will have accomplished the usual objects; it will have: Secured an equal vearly cut. Perfect regularity of Age Classes. A normal Growing Stock. Maintenance of the twenty-year Rotation. 140 FOREST REGULATION If continued this plan will effectively prevent overcut and undercut, and always furnish material twenty years old or of desired age. size and quality. bh. In Selection Forest. Assume: Forest of one Township (about 22000 acres). Method: Selection. Rotation: About 150 years, judged by diameter of trees. Period of Return: Twenty years. Growing Stock: 5000 cubic feet per acre by actual cruise. Level country, can log anv part desired. Regulation of Cut here divides the forest into twenty equal parts as in the case of Coppice, and plans to cut over about 1100 acres or about twenty-eight forties per year. Since only part of the timber is cut at each return, the question at every cut is: how much, or what proportion of the stand should be taken? Generally this is left to the forester, whose good sense and knowledge of silviculture are relied upon. Dut in many cases this is unsafe and it becomes necessary to decide either on the quantity or volume to remove, or the proportion of the total stand which may he cut. In wild woods the matter is complicated by the great irregularity which exists, and also by the large amount of old, defective, crippled, undesirable material on the ground. Here it is often necessary to combine regular Clear Cutting, or Clear Cut with seed trees in the regular Selection Method, and much freedom must be of necessity allowed to the forester. The first going over generally takes over-ripe, ripe, and defective, it is a cut of ripe tim- ber combined with an improvement cutting just as far as market and good silviculture allow and demand. These conditions become better with each return, provided the overcut, which is almost sure to occur in many cases, does not hurt the forest to a point where reproduction is effectively prevented or seriously retarded. In planning the first cut the stand to be left on the ground is the principal consideration, for the irregularity of the woods prac- tically prevents more than a general figure of volume per acre or of proportion to leave and take. After several returns, a more definite regulation or volume check can be applied. FIXED YEARLY CUT {41 For this Volume Check, in using the Fixed Yearly Cut Method of Regulation for the Selection forest, Hundeshagen’s reasoning appears quite sufficient. This, as modified by Von Mantel permits the cut to take 2G/r every year. In our forest of 22000 acres, with a growing stock of 5000 cubic feet per acre or a total of 5000 X 22000 == 110 million cubic ft. of Growing Stock and a rotation of 150 years (decided upon) we could cut 2 X& 110,000,000/150 = 1,460,000 cu. ft. per year. Since this 1,460,000 cu. ft. is cut on one-twentieth part of the town- ship or 1100 acres, the cut per acre is 1,460,000/1100 or about 1300 cu. ft. per acre, actually cut over. “\ simpler way is: Cut = 2G/r 20 per acre at each return. ‘This per acre and with above premises: 2 X 5000/150 20 =: 1300 cu. ft. With a twenty-year return then the cut takes 20/r (2G) -=40/r G. With an ordinary rotation of 100 years this would mean about 40% of the growing stock. From a silvicultural standpoint this would be a very heavy cut, and for rotations of 100 years and less, a twenty year return is too long except for pure stands of intolerants. With a ten-year return and a cut of 20% a much better silviculture is possible. ‘She amount or proportion to take out at each return depends on site, tolerance of species, market, etc. With intolerant pine more must be cut to enable reproduction; on poor sites less should Le cut to avoid soil deterioration; with poor site and poor market, good silviculture must he sacrificed and more taken to make possible selling the stuff at all, etc. From the foregoing it is evident that in the Selection Forest, Area Regulation is, of necessity, combined with a Volume Regula- tion or Volume check. This method of logging over a definite area, and covering a property in a given time is perfectly practical and advisable. As in all cases of Regulation the property should be examined from time to time, preferably every ten years, and a plan adapted as the condi- 142 FOREST REGULATION tions of reproduction, growth, and of market suggest. Criticisms against this method are generally based on the false assumption that when a division and plan is once made, it must be followed without regard to changed conditions in the forest.* Where Shelterwood and Clear Cutting \lethods are employed, a division into smaller lots and into Cutting Series and also a more flexible plan become necessary. In the Selection forest the slow and easy wavs of nature are relied upon, every lot receives a thorough cutting over every 10-15 years, mishaps in reproduction are reduced to minute areas and are left for nature to take care of. In clear cutting and planting things are forced, every acre must. justify extra expenses and therefore every acre must be in a position where it can receive attention and care at any time. -\s soon as such a stand lags behind in growth the plan of regulation must provide for its removal. All this is not possible with a fixed yearly cut in a large property, and therefore this method has generally been re- placed by the following, either in ordinary or limited form. 2. Area Allotment. ‘The following example illustrates this Method: Plan for 1914-1933. Area of Forest: 4000 acres. Species: Spruce. Method: Clear-Cut and Plant. Rotation: Too years, hence five age classes. All one site, no “reduction of areas” necessary. Yield per acre of 100-year old stand fully stocked: go00 cu. ft. Plan of Utilization: all stands in Age Class V (80-100 years old) and older, are considered ripe; also all defective stands and stands in poor condition of growth. a. The first step is to prepare a table of Age Classes from the detail field examination. From this a table of allotment as follows: * Such a misconception of Working Plans in general, and especially of Plan for Regulation of the Cut has led to much unnecessary controversy, and has often led the practicing forester to speak of the Plans as “Paper Jokes.” See ‘Michaelis, “Betriebsregulierung.” 1006.

Total have: 470 | 1130 | 1050 930 | 420 Should have: 800 | 800 | 800 850 | 800 b. A study of this table of Age Classes tells the forester : That the-forest is deficient in ripe timber and quite irregular, has plenty of middle age stuff, and lacks in young stands. It also tells that certain stands in Age Class LV, like sa and 4a can well be placed with ripe timber to be cut during coming twenty years. Also that the stand in lot ten though only forty-one years old should be cut and the Jand replanted. c. In this way the forester has the whole situation placed clearly before him, and he is enabled to shift the stands and decide definitely what is to be cut during the next twenty years. In this, particular case he might shift all defective, all specially large timber from the second column into the first, so as to increase the cut of the next twenty vears and avoid having too large a mass of stuff on hand in twenty and again in forty vears from now. If the market takes stuff 60-89 years old he might readily make I44 FOREST REGULATION up, in this way, a full 800-acre cut for the first period. Even then he would not prevent entirely some of the timber from going over the 1co years, unless he is ready to cut over 800 acres in the period 1954-1973. d. In twenty years the forest is again examined and described ; an entirely new plan is made; the stands are again allotted to various periods in keeping with the condition in which they are found in 1934. e. To this Regulation is normally added, an estimate of the amount of timber which the Stands finally placed in the first column (period 1914-1933) will furnish when cut. A common method is as follows: Lot 6, 90 acres, 0.8 stocked will be (presumably) 100 years old when cut (middle of period) and will then furnish per acre: 0.8 X Q000 cubic feet or 7200 cubic feet per acre; total go X 7200 = 648,000 cubic feet. Of late the importance of Volume check has in- creased. f. These estimates are not binding, area rules. lf the cut for the period of twenty years, is set at 7Go acres, the yearly cut is 760/20 == 38 acres. g. The Method of \rea Allotment was first clearly developed by Cotta; it has been modified in keeping with progress in the Regularity of State forests. Instead of insisting on a rigid continu- ation of a first plan, the plan itself is renewed at regular intervals (ten years Saxony, twenty years in other states). ‘This method has outlived and displaced practically all others, and its superiority has induced the Prussian Government to continue it in official Instruc- tions of 1912. In criticising this Method the mistake is usually made of assuming that because the forester works out a few good tables which tell him exactly the age and condition of every stand, and because in making these tables he places the stands in different period columns, the Plan is binding for an entire rotation and the Method correspondingly rigid and useless. Part of this mistaken criticism is due to the fact that a century ago when forests were cheap, and money scarce, the administration, even such excellent men as Hartig, did not dare to hope that the forests would stand the expenses of re-surveys and Plan-revisions every ten or twenty years. AREA ALLOTMENT 145 That these Area Allotment Plans were often misused by narrow- minded, domineering officialdom was no fault of the Plans. h. Area Allotment is suited to any forest, to all conditions, provided there is market for the material to be cut, and for very irregular, mismanaged forests it has no equal. The very fact that it demands a careful study and placing before the forester (on paper) of every stand in the forest assures continued attention and care of every tract, a matter so easily overlooked and forgotten in a property of which the inspector or owner may not see large portions in a whole lifetime. 3. Limited Area Allotment or Judeich’s Method. “Judeich’s Method” (Schlich); “Alters Klassen methode” (Judeich). “Bestands wirtschaft” of Judeich and other authors. This is a method of Area Allotment; work in field and in office is the same as in the foregoing, except that the columns for periods 2-5 are left out entirely. Stands for the next twenty years (in Saxony ten years) are picked out as before, i. e., ripe and defective stands, and also some stands which must be cut to build new lines, etc., areas are added and if this sums up to more than the normal cutting area for the forest, reductions are made. In these reductions or additions the condition of younger stands is also considered. Advantages claimed for this Method lie in the greater freedom of action for the forester. It is usually claimed that this Method only binds the action for the coming ten or twenty years, while regular Area Allotment is claimed to ke binding for an entire rota- tion. This is not true. In a very irregular forest, consideration of the younger timber is so important that some tabulation must be done to bring out the facts. Whether this table then stays in the plan or goes into the wastebasket may not be important, but, as Schilling correctly says, it ought to stay in the plan. This method of the Limited Area Allotment was the natural result of the rapid progress in forest regulation during the years 1820-1870. ‘Ihe State forests of Saxony for instance had become so regular, work in the forest was so orderly and reliable that there was no further need of bringing into the Working Plan any stands which were not yet ready or in need of cutting and replanting. 146 FOREST REGULATION a. This Method gained favor among practicing foresters chiefly because it relieved them of some pressure from upper offices, and prevented somewhat the office insisting on the old plan, long after conditions of the woods made new provisions necessary. But all this has nothing to do with the Method itself. The new departure in the Prussian Instructions of 1912 does all this much better by giving the forester himself the task of making his own working plans. b. In Limited Area Allotment, Volume Check is generally demanded. The timber of all older stands, (ripe and near ripe and also defective) is estimated, and the Volume for the Period and each year set down in the Plan. This is merely estimate, and is chiefly intended to prevent great fluctuations in amount of stuff to be sold. Estimates even in Saxony are generally ocular when made for this purpose. c. In anew country and on large properties, these Area Allot- ments can not be used without modification. It is useless to allot an area of forest to the period 1914-1934 when it is evident that none of the timber on this area can be sold. In these large proper- ties, now practically restricted to the far West, accessible areas, or areas with market, must be temporarily separated into independent Working Sections if an Area Allotment is to apply. D. Volume Methods of Regulating the Cut. In trying to Regulate the cut by Volume the aim is to cut each year about as much as grows in the forest. In cases of wild woods where growth and decay practically balance, the cut also takes what the forest grows, i. e., the cut replaces decay.* In any case of Regulation by Volume the question arises: how much does the forest produce, or how much can be cut without cutting into the capital? *It may be argued that hy doing so the cut by man, and decay or har- vest by nature taken together make an overcut, i. e., removes twice the growth. There is truth here, providing the forester has no choice of stands at all. If he has market for all, and is in position to get at old and defective stands, then the above reasoning is not truce. Jn any case, the importance of this decay is lessened year by year. Nevertheless, this matter is of some weight and indicates need for conservative estimate in setting the Cut in Volume. VOLUME AILOTMENT 147 I. On a property of 20,000 acres of forest it is utterly impos- sible to measure accurately the amount of growth. And herein lies the weakness of all Regulation by Volume. In area regulation quantities are exactly known, if rotation is eighty years, the forester knows that a normal cut is 20000/80 == 250 acres. Volunte Regula- tion, on the other hand, is fortunate if Growing Stock is known within 15%, and as to the growth, it can only be inferred from a comparison to known conditions (Yield Tables) or from stump- and stem-analyses and an estimate of how far these analyses apply in the actual Stand. In well regulated forests of Spruce in Saxony these estimates are amply reliable, in wild woods they rarely are. 2. For these reasons Volume Regulation is never more than an initial step and has given way to area regulation wherever forestry has made real progress. But as a beginning it has value, and this is especially true under conditions where only portions of the forest have any market at all, and where large areas are in a formative state, of great and certain value in the near future and yet of no sale value at the present time. 3. When Regulation has decided the Volume which may be cut, say 15,000 cords from 20,000 acres, it has done practically all that Method of Regulation of the Cut can do and the rest is a matter of proper distribution, i. e.. what stands to cut, and of silviculture. For this reason most Volume methods attempt only to estimate the amount of timber to be cut. 1. Volume Allotment. The following case illustrates this method: a. Plan for 1914-1933. «\rea of forest 20,000 acres. Species: Pine. System: Clear Cut and Plant. Rotation: 80 years, hence 4 age classes. Site J—2o0% of area, yield at 80 years 7000 cu. ft. per acre.

All thinnings are lumped at 300 cubic feet per acre for each thinning, these to come twice in every period, i. e., every ten years, so that each acre is credited with 600 cubic feet, of thinnings, for each period but none during the period in which the stand is planted. c. From the above Plan it appears that the first Period (1914- 1933) is deficient in ripe stuff, that the forest is quite irregular, that Age Class II is unduly represented. As in the case of Area Allot- ment, there is considerable shifting of stands from the second into the first period column. All defective, broken stands such as those of lots five and eight are assigned to the cut of the next twenty years. In this way easily eight million cubic feet can he assigned to Period one, with the expectation that in 1934 a re-shifting of part of what is now Period No. 3, into Period No. 2 will take place. d. In the above plan the Cut of eighteen million cubic feet is definitely located through selection of ripe stands. But the forester has abundance of choice, as to the stands to be cut the first, second. etc., year. If at any time during the twenty years, or the life of this plan one stand appears more in need of removal than another there is nothing to hinder the forester. In this way every stand can receive attention and all timber cutting may he decided by financial or other considerations, provided always that the forest is in right condition, is properly divided into lots and Cutting Series, and receives proper care in silviculture. Since the timber alloted to the next twenty years’ cut is not all cut in one year, but in twenty years, there is quite an appreciable amount of growth on this timber. This growth is usually added as a lump sum, it being assumed that the whole mass grows for one-half of twenty years as an average. So if twenty million feet are assigned and they may be assumed to grow at 2%, the total mass is 20 (1.02"°)== 1.22 (20) = 24.4 million feet. e. The Method of Volume Allotment as outlined above re- sembles Area Allotment. Jf well done, and properly revised every twenty years there is no reason why this plan should not work for 150 FOREST REGULATION greater regularity of Age Classes, and with this for a better forest business. It works entirely with estimated quantities in its allotments, and it works in part with quantities or stands not yet even planted. ‘This defect is easily overstated. The farmer who buys a farm, practically estimates the value of the farm on the basis of crops to be sown and harvested in the future. This method was brought into prominence by Hartig, and made. for a time, the official method of the state forests of Prussia. It did good service, but was later displaced by the more accurate Area Allotment which works with quantities accurately measured and permanent. f. Best critics usually charge that cuts of equal amount are not always desirable, that if much old timber exists there should be freedom to remove it, and also that estimates for the future are too uncertain. They also state that this method has more regard for the interests of the owner and market than Area Allotment.* All through these discussions it is apparent that objections are based on conditions which are not necessarily parts of the Method, but are more mistakes in the application of the Method. 2. Growing Stock Methods. Austrian and Hundeshagen. In these Methods the cut of timber to be taken each year is gauged by the amount of Growing Stock on the land. a. Austrian Method and Heyer’s Modification of this, or Heyer’s Formula. In wild woods with their irregularities of growing stock. and age classes, and their long rotations (life of tree) a particular forest may have more growing stock than is necessary to get the best growth under shortened (man-made) rotation. In such a case it is desirable to cut, not only the growth, but also to cut some of this surplus, stored-up wood capital, and gradually reduce the growing stock to a normal or proper amount, in keeping with rotation. This is done according to the following formula: * See Martin, p. 2c9; Judeich, p. 356. AUSTRIAN METHOD 15! Yearly Cut = Yearly Growth -+ Actual Growing Stock — Nor- mal Growing Stock divided by an arbitrary period of years, or Ga —-Gn Cut == Crowth + er te ; Gr—Gn ; Also written: Y= Ir + —————_......... (Schlich).* a Where Ir is Real or actual Growth or “increment”, Gr is real or actual Growing Stock and a is a period of years set arbitrarily in keeping with conditions found on the property. The formula clearly shows the plan: the surplus, or amount of growing stock over and above normal, is divided by a and the 1/a part is added each year to estimated growth and is removed in the cut. It also shows that if actual growing stock is deficient, as in badly overcut forest properties, the quantity (Ga — Gn) /a becomes negative, and the 1/a part of this deficiency, is deducted from the estimated growth, the cut is lessened by this amount, and there is a saving up of growing stock to restore it to a proper or normal condition. To supply concrete illustrations for these methods using the Growing Stock as a gauge in Regulating the Cut, the following premises are assumed : 1. Actual Conditions of the Forest to be Regulated. AREA ACRES. AGE YEARS. STOCKED. 70 TO 0.9 130 20 0.7 60 30 0.8 200 40 0.7 150 50 0.7 40 60 08 650 acres of woods. *In most books the Austrian Formula is written: Ga— Gn Cut = Growth -- ——_—_ which would assume that in the Austrian form it was prescribed that the surplus must be spread over an entire rotation. And it is pointed out as a special distinction of Heyer’s formula to introduce a as an arbitrary period in place of rt or the rotation. Von Guttenberg declares this to be an error in his book (p. 154) and his reasons are convincing. i52 FOREST REGULATION 2. Yield table. Vine, Site IT, rotation sixty years, fully stocked.

Calculated on basis of Current Growth as per Yield Table 93 cu. ft. 70 cu. ft. In trying to regulate the cut of this forest by the Austrian- Heyer Formula we have: Cut = Growth + (Ga— Gn) /a. RY AUSTRIAN METHOD 155 actual growth is calculated (as under 6-b, see above) on basis of Average Yearly Growth of Ripe timber, in this case 68 cu. ft. per acre. Actual Growing Stock (Ga) is also calculated from Average Growth of Ripe timber (as in 4-b of preceding tables) and is 2380 cu. ft. per acre. Normal Growing Stock per acre is Yr/2 or 2800 cu. ft. per acre (see 3a and 4c above). It is merely necessary now to decide on a, the period during which this regulation should take place. In this particular case there is not a surplus of Actual Grow- ing Stock, but it is a deficit which should be corrected by saving in the cut. The large area of twenty year old and of forty and fifty year old stuff and the fair condition of these stands (stocking 7+) would indicate that there is no great need of saving heavily. For this reason the saving up is spread over an entire rotation and it is decided to make a ==r in this case. Using the above data, then, the Cut = 68 -L (2380 — 2800) /60 = 68 -— 7 = 61 cu. ft. per acre, and for the forest of 650 acres the Yearly Cut is 39,650 cu. ft. per year. The Austrian Method or Formula was not an invention of the forester, but of an office man, and was introduced not for regulation but for valuation of forest properties. It does not presuppose or prescrite any particular method of silviculture, division, regularity of age c’asses, or any particular order or sequence of the cut. The cut may be made at any point. But this method does not forbid forest division and order in the work, and it is no fault, therefore, of this method that such improve- ments are not prescribed in any particular plan. It can Le applied to any forest and under any conditions, and is particularly well suited to irregular wild woods in large properties and to the Selection forest. It will at once set a reasonable cut, prevent overcutting and work in the direction of order, and greater regularity, not only of Growing Stock in Volume, but also of Age Classes. Proof of the value of this method is given by the citv forests of Zurich where this method has long heen in use, is pre- scribed officially by the kanton government, and has led to perfect regulation under the master hand of Director Meister. In these forests in 1882 the period a of the formula was set at r (rotation) or ninety years for Working Section I; at forty years in Working Section II; and only twenty years in Section ITI of the Sihlwald. 156 FOREST REGULATION The fact that this method, like all volume methods, works with estimated quantities, and gauges such quantities for the future is not nearly as serious as appears at first. Just as in farming, average vield per acre for twenty or more vears can very well be estimated and is relied upon in setting a value on the farm and its business. so it can be relied upon in forestry, where the crop is far more independent of the seasonal fluctuations of growth. The important point here is not that estimates be accurate, though of course this is desirable, but that the plan is followed faithfully and that the prop- erty is re-examined and the plan revised at regular intervals to suit changed conditions. For it can never be emphasized too much that the forest is a living body, and reproduction, growth, cut and decay bring decided changes every year, so that no plan can be relied upon for any length of time. In applying the Austrian-Hever Formula to Wild Woods and to Selection forests, actual growth and Normal Growing Stock are obtained from Yield table studies, and Actual Growing Stock can only be obtained by cruising: the property. That this method or formula is not applicable in the case of a small forest in which the entire growing stock is unripe young stuff is self evident. In such a case there is nothing to do but wait until the stuff is ripe to cut. To cite such cases in evidence of the deficiency of the Austrian Method can not help science or practice. It is also evident that in the case of large wild woods properties some errors must creep in wherever large bodies of old defective stuff can not be sold. In such cases there is not only a cut, but there is also a natural harvest or decay which needs to be considered. But such difficulties are of minor importance and can be largely elimin- ated by separating portions of the property which have no market and simply treating them, temporarily, as separate Working Sec- tions not yet ready for Regulation of Cut. b. Hundeshagen’s Method and Von Mantel’s Modification of this. Hundeshagen assumed that the relation of Growth (or Cut) to Growing Stock should be the same in the unregulated forest as in the regulated one. His formula: Cut in ordinary forest /Growing Stock of this forest = Cut in Regulated Forest/Growing Stock in Regulated Forest, or Cut/Ga = Yr/Gn.°. Cut = Ga (Yr/Gn). LY II[UNDFSHAGEN 157 Ga is based on actual inspection of every stand, and either esti- mated by cruising, or else as in 4a of above tables, by ascertaining age and condition of stocking and then computing volume by yield tables. Gn is obtained by summation of Yield table as done in 3b of above examples. Yr is the stand of one acre r vears old as per yield table. According to the above premises the cut in the small forest there assumed would be: Cut = 2110 (5600/146000) = 2110 (1/26) = Ga (Cut on r acres, ‘Stock on r acres) == 2110 (3.8% ) = 80 cu. ft. per acre. In this case then the yearly cut would take 80 cu. ft. per acre or 650 X 89 = 52,000 cu. ft. in all. Von Mantel evidently going on the assumption that a little more or less in the estimate would not change results in ordinary cases decided to use Normal Stock as calculated from Yr and r, i. e., Yr X r/2; in our case 5690 X 60/2=—= 168,000 cu. ft. for 60 acres. In this way the formula is simplified to: Cut = Ga Yr/Ga= Ga Yr/YrXr/2 = Ga 2/r which merely follows out logically the assumption of [lundeshagen ; and is based on the fact that in a regulated forest the growth in the forest during rotation equals twice the growing stock found at any time on the land, as stated under Normal forest. In the assumed case then: Cut =: 2Ga/r or Cut = 2110 X 2/60 = 70 cu. ft. per acre, or about Io cu. ft. Jess than by the regular Hundeshagen calculation. Von Mantel’s Modification of Hundeshagen’s formula is a very useful devise to start the regulation on large wild woods properties. It adapts the cut to the actual growing stock on the land, whether this is in excess or below normal. In large properties stocked with pure stands of intolerants, Western Yellow Pine, Lodge Pole, etc.. where the stands are largely even aged and where some of the Age Classes are practically want- ing, application of either the Austrian or Hundeshagen Method needs a careful consideration of actual existing conditions. What has keen said with regard to the foregoing methods applies here. This method merely estimates the proper cut to make 158 FOREST REGULATION and does not consider other provisions of the plan. But this fact does not prevent a proper development of forest division, order in cutting, or necessary revisions with their surveys and estimates of all parts of the forest. This method recommends itself by simplicity, is adaptive, and fully competent to develop a well regulated forest. Nevertheless, this method never gained favor and was never employed by any of the State forest Departments so that it stands today without any important results or experience, and merely with an academic his- tory in text books. c. Combined Methods. Of these the Combined .\llotment where the table was made sufficiently large to accommodate columns for areas and for volumes has been the most important. Since this, in actual practice has long changed to the Area Allotment with volume as a check, there is no occasion to go into it further.* d. “Diameter Limit” as a Method of Regulation. Diameter limit has been recommended and applied in some of the early efforts in forestry, it has become very generally known, appealing, as it does, to the man in the woods. Its object is not really Regulation, but merely an effort to preserve the forest from immediate devas- tation. For this purpose it has served well, at least in a few cases, and is perfectly suited to hclp in most forests. But good silviculture alone condemns any rigid application of diameter limit for any real forestry, since the runt or small tree is often older and more worth- less to keep in the woods. If this runty stuff is to be cut, then the enterprise is no longer based on diameter limit. As a means of Regulation of Cut it fails because it is based on the mistaken assump- tion that diameter and age are proportional, an assumption always wrong in any forest, regardless of care, and wrong to an extent of 30-50%, i. e., in the eighty year old stand, even in a well cared for forest, the largest tree differs from the smallest tree by easily 30- 50% in diameter. Even where this diameter limit is used, either an area regulation or a volume regulation such as \’on Mantel's should he added. *For complete list of the many methods published at different times, see Recknagel, “Theory and Practice of Working Plans.” APPLICATION OF METHODS 159 In the Selection Forest, diameter limit is used to assure, ap- proximately, the desired rotation. Here the assumption is that the good trees, forming the harvest part of the cut, (in distinction to stuff cut for improvement and thinning) are of a certain size at a particular age, an assumption amply accurate for the purpose in hand. III. Application of Methods of Regulation of Cut in the United States. Regulation of the Cut in amount (Area or Volume) is very important in development of any Forest property to prevent un- reasonable overcutting which could defer any desired regularity of income for a long time and bring permanent injury to parts of a forest. But it is not as important as is good protection and silvicul- ture and a suitable division of the forest, for these together with any degree of orderly sequence of cutting will in themselves work in the direction of regularity and will in all forest properties largely replace Regulation of the cut and necessity for special measurements and calculation, just as they have done in parts of the old world. In time Regulation must simplify itself in any good forest into the task of going over the property about once in twenty years, and picking out the stands either ripe enough to cut, or stands in had condition and therefore in need of cutting, and assigning these to the next twenty vears’ work, area indicated by the rotation adopted. Tf this is 100 vears, then approximately one-fifth of the entire forest should be assigned to a period of twenty years. But in the present beginning stages of forestry, such simple and satisfactory procedure is not possible. More than 75% of our large forest areas are not even accessible and assigning an area here to a particular time, can have no meaning. For this and other reasons it is necessary to use other methods, and it is interesting to see how these may apply to particular forms of forest and conditions, as they now exist in the United States. The following suggestions are general. 1. Regulation in the Woodlot. It may seem pedantic to speak of a regulation of the cut in a twenty or forty acre woodlot. But experience in the woodlots of our country shows clearly that nct only are such woodlots suffering 160 FOREST REGUI,ATION for want of better silviculture, but also from a lack of orderly cut- ting. Whether hardwood in selection forest, coppice, or clear cut and planting. perhaps the three simplest and best methods for or- dinary case, such a woodlot is bound to gain in value by some regulation. In our ordinary hardwood lot, the method is usually a mixture of coppice and selection, but the common way of cutting is to overcut at the edges, and neglect to cut the interior, so that most of them appear like half cleared pastures along their border, devoid of protection against wind and sun, while at the interior there remain old, large crowned, usually defective trees which should have been removed long ago. For this reason growth in these lots is small, in spite of good quality of site, and it is small in quality as well as volume. Simple regulation by fixed yearly cut, with each year’s cut marked by posts is satisfactory, and will. if properly followed lead to better and larger growth and assure a vearly cut of value. A forty acre lot in selection method might well be divided into ten four acre lots. one lot to be cut over each year. ‘he amount to take out should. ordinarily, not exceed one-fourth of the total volume. If it is estimated that the woodlot has thirty-six cords of material per acre. all told, then the cut should take about nine cords of this. This nine cords should be made up of old, ripe stuff and defective material. If there is quite a large amount of this old and defective stuff, it is better to take a smaller area, cut heavier and plant up all openings made by removal of the old stuff. 2. Regulation in the Large Selection Forest. a. In Level Country. The assumption here is a forest like those of the Great Lakes Country with market for everything, and simple winter, snow and ice-road logging. Here also a simple Fixed Yearly Cut Regulation will prove perfectly satisfactory. The areas in such a case need not be marked on the gound, it is sufficient to indicate each year’s cut on a map or plat showing the property, and this cut may very well follow present logging wavs of cutting by forties. A volume check is needed, and if a twenty year return and 120 vear rotation is decided upon, alout 30%. of the volume of the growing stock may be taken. In such a case, the first cutting over of the property should not adhere too rigidly to the volume check, but leave quite as much freedom to REGULATION IN SELECTION 161 silviculture as market permits. With the selection method to fol- low, it is quite immaterial where the cut begins, whether in one or several places, and what its rate of progress at any point. Similarly it is permissible to ignore conditions of types and future Working Sections as well as a division into Cutting Series. in a property of this kind simple Regulation by Volume will answer. If Von Mantel’s formula is used and rotation is set at 120 years and period of return at twenty years the formula as in the above case provides a cut of about 30% of the growing stock on every acre cut over. For example: rotation 120 years; period of return, twenty years; growing stock forty-five cords per acre, all told; area of forest 10,000 acres. ‘The formula: Yearly Cut = G2/r==2 Xx 10,000 K 45/120 ==7500 cords per vear. But since the plan calls for a return every twenty years, this 7500 cords is cut from 1/20 of the area or from about 500 acres. In this way Regulation though really by volume, at once involves an area consideration and takes the form of a combined method, just as in the above case where regulation started with fixed yearly cut, and merely used Volume as a check. lf in the foregoing plan a definite period of return is left out, regulation of the cut merely prescribes that it take 7500 cords and does not specify that this come’ from 500 acres, but permits that a heavier or a lighter cut per acre be made. While in this form it becomes strictly volume regulation, yet in actual practice the plan of silviculture also sets its limitations and if the forest is fairly uniform, the forster naturally cuts different tracts in about the same way,-and covers nearly the same area each vear. But this again leads to a more or less uniform period of return and with this to a combination of Volume Regulation and Area Regulation. With a forest of hardwoods and Hemlock on good sites, as is here considered, the question arises: should not this good site be cleared at once and some more profitable species replace the hard- woods? No doubt this is true. But to the owner of 10,000 or 20,000 acres this would mean quite a sacrifice in growth and in valuable voung growing stock. A much better way for the owner who wishes to transform this Wild Woods into a paying forest 162 FOREST REGULATION business, is to cut it over in the manner outlined above and plant some Spruce and White Pine into the open spots each spring and merely add to the valuable stuff, rather than destroy and replace it. On areas where old defective stands cover practically all the ground, and where little of value is left after logging, the land should at once be planted to better species. With change later on, from Selection to Clear Cut, Regulation should change from Fixed Cut to Area Allotment. b. Regulation in Large Selection Forest in Mountains. In forests Jike those of the White Mountains, Maine and the Appa- lachians, logging normally starts in the lower valleys and proceeds up the valley and its branches. In this way the point of beginning and the order of progress are prescribed by topography. Usually. too, the rate of progress is not altogether arbitrary, and in cases where the timber must be driven on small streams, it is distinctly limited. This situation is often complicated by the fact that only conifers can be marketed, as in the northeast or only part of the hardwoods, as in the southern mountains, etc. Example: area 30,000 acres; forest of spruce, more or less mixed with hardwoods, the latter not vet marketable; method: selection with a rotation about 120 years, indicated by a thrifty ten inch tree. In this case good silviculture must endure, at least for the present, a very unsatisfactory situation and cut the species to be favored, and Jeave the very species to he restricted in possession of the ground. Good regulation, too, is violated, since more than 50% of what is ripe and in need of cutting must be lett on the ground for lack of market or rather of roads. In cases of this kind ordinary logging methods select each year the area to be logged, develop on this area the necessary roads and go ahead. It is a fixed vearly cut without a plan for the future. Regulation here needs only to improve on this method, long fol- lowed, prepare a proper set of reliable maps, select ‘fixed vearly cuts” on the map first and in the field afterward, and plan these cuts for the entire property. Jn all likelihood this plan would need modification for the first and second going over the property, but it would certainly be a great step toward an orderly development of this property to have at the office reliable maps and a definite well REGULATION OF CUT 163 based plan, and in all cases would be far better than to leave this most important of all tasks to the woods foreman who happened to be on the job that particular year. Volume check here should be waived and the matter left to good silviculture. In pure stands of Spruce danger from windfall alone demands a light cut; in hardwoods the cut should try to favor reproduction of Spruce at the expense of hardwoods, and certainly leave enough Spruce to assure this, or else assist artificially. In all cases, if the selection method is used, the cut should leave a fair stand sufficiently resistant to wind and snow injury, and especially avoid large areas cut clear, and even smaller ones (ten acres and over) unless these can at once be re-stocked by planting. Properties such as are assumed here are not rare today (1914) and it is surprising how large an amount of timber still is left to die and decay in the woods of the New England States, simply for lack of roads and railroad facilities. If part of the money taken from these properties were put-back for their improvement it would be an easy matter to change this condition. 3. Regulation in the Southern Pinery. A fine climate which makes even lean lands excellent forest sites with remarkable growth together with pure stands of intoler- ants, calls for the Clear Cut Method of silviculture. ‘l'o secure best results and avoid serious and avoidable loss, the forest should be surveyed, divided preferably on the United States survey plan; it should be carefully examined and described and the plan should bring and keep the exact status of every forty before the forester and the owner. This is done hetter by the plan of Area Allotment which de- serves preference and in time will undoubtedly displace anv other in this region. In the beginning, when numerous ripe stands can not possibly be reached during the first “period” of twenty years, these ripe stands are placed in the plan to suit conditions. On properties having a very Jarge amount of overripe stuff, usually accompanied by great masses of defective material, it may prove advantageous to cut the property or at least parts of it over on the Selection plan. Jn this case volume check may well he left out and the degree of cutting left to silviculture. 164 FOREST REGULATION In these properties of the Southern Pinery, danger from insects must be considered and may require immediate attention in regulat- ing not merely the cut in Volume but also in location, 1. e., attend to a proper distribution of the Age Classes, or stands of different age, and with this of Cutting Series. For it is just in these forests of rapid growth where changes in conditions come fast and often, and where every stand must be in position for independent treatment. 4. Regulation in Lodge Pole Pine. Typical case: property of 500,c00 acres; Rocky Mountain coun- try. largely platean and large slopes, fairly accessible. Forest practically pure Lodge Pole; at higher altitudes a timber-line country with Engelman Spruce, often mixed with Lodge Pole, pri- marily protective forest. Considerable areas of bare, grazing lands. Market is good for railway ties, poor for lumber. The following conditions hold: a. Total Area: 500,000 acres. b. Area in woods about 400,000 acres; rest in prairie and waste. ec. Conditions of wood lands as per detail cruise hy forty acre lots : 1. Cut-over lands. and burns practically bare now, 41,000 acres with reproduction expected in next twenty vears. 2. “Jack Pine”, stuff helow 4” d. b. h. and 25 ft. in height 142,000 acres. 3. Poles, average 5” d. b. h. (4-6"")—6,000 acres. 4. Stands of Larger Poles 6-10’’, 80-120 vears old—none. 5. Merchantable Timber 120-250 years old—194,000 acres. d. Rotation is set at 200 years, (approximate average age of mature timber), and assumes that technical rotation continues to be based on size required for ties. On this basis the above conditions may be stated thus: PERCENT SHOULD BE IF OF AREA. REGULATED. Bare areas to reproduce in next 20 years...... 10% 9% Age Classes J and TI, 1-40 years old stuff..... 35% 18% Age Classes IIT and IV, 40-80 year old stuff... 6% 18% Age Classes V and VI, 80-120 year old stuff... o% 18% Age Classes VIT and X, 120-200 years or older. 48%, 36% REGULATION IN LODGE POLE 165 From this statement it is evident that the property has too much bare land and young stuff, is practically without middle aged stock, but has an abundance of ripe timber. If a continuous supply is to exist here Regulation must get along with what timber there is in age class VII and older, until the young stuff is sufficiently large to cut. The probability is that rotation is set higher by about 20-40 years than is absolutely necessary, even for average site. e. Sites were not differentiated in the examination of the property. f. Growing Stock of merchantable material on the 194,000 acres of old woods is estimated at 3200 million feet b. m. over 10” d. b. h. or about 16,000 feet b. m. per acre. Good (fully stocked) stands on average site ruin 25,000 feet b. m. Volume of young stock is neglected in the calculation. g. Actual average growth of ripe timber is set at 16000/200 = -80 ft. b. m. Normal average growth of ripe timber at 25000/200 = 125 ft. b.m. Actual Growing stock per acre is 3200 million (ft.)/ 400,000 (acres) == 8000 ft. Normal Growing Stock per acre is 25000/2 == 12500 ft. h. Plan of Cutting, i. e., the silvicultural plan is to cut the land over by the selection method, taking about 30-35% of the stand of any one acre, the rule being to “leave a forest cover.’ Later on, (within 50 years) it is expected that the Clear Cut system with seeding from the side can set in. i. Regulation, for the present, must set a reasonable Volume check, i. e., it must determine the amount of timber which may safely be cut without over-cut, and with full regard for the conditions, particularly irregularity of age classes, and assure a sttstained yearly cut from the property. Several methods are tried, as follows, and their results compared. j. Fixed yearly Cut, modified. To apply this method, the 189,000 acres of bare land and young stuff are left out of considera- tion for the present since no cutting can be done on these lands. For the other 194,000 acres the plan provides for a 4o year return, a yearly cut of 194,000/40 or about 5000 acres, and silviculture indicates a cut of 16000/3 or about 5 M. ft. per acre. Total Cut: 5 M. X 5000 (acres) or 25 million feet b. m.. to be cut wherever 166 FOREST REGULATION timber sales can be made, and thus the particular areas to be decided upon from time to time. It is expected that long before the end of forty vears, the property is again examined and a new plan is made in keeping with conditions as they will then exist. k. Hundeshagen’s Method with Von Mantel’s modification. TIere the Cut = 2Ga/r. For our case: Cut == 2 X 3200 million ft./200 = 32 million per year. On this plan the present supply would be cut in too years and at that time little material over 120 years old could be expected to exist on this property. For this reason the thirty-two million must be regarded as about the maximum cut allowable. 1, Austrian Method, or Heyer’s Formula. Ga— Gn Cut = Growth = In this case: Cut = 80 + (8000 — 12500) /200, or about: 80 — 22 == 58 ft. per acre. For the property : 58 400,000 == 23.2 million feet. It will be noticed that, in spite of the large amount of old stuff, actual Growing Stock is smaller than normal Growing Stock, so that it is not a surplus, but a deficit which must ke spread. Since there is no special reason for spreading this over a shorter period, it is distributed over an entire rotation, i. e.. a is made equal r. m. Hufnagle’s Method for smaller properties, might also be used here with some modification. JTTe prescribes estimating the volume of stuff older than half the rotation and spreading this volume over the period, i. e., over half the rotation. In our case this might well be used: Growing stock older than 1/2 r == 3200 million ft. Time before the younger stock will be ready for the axe about 125 years, and for this period the merchantable tintber should be made to last. Hence: Yearly Cut == 3200 million ft./125 == 25.6 million ft. n. Good silviculture demands that as far as possible oldest and most defective stands should he cut first. But on a property of this kind such requirement must often be disregarded for lack of op- portunity to sell the material. For this reason the cut will be RNGULATION IN YELLOW PINE 167 accompanied for some time by a large amount of unavoidable loss in old and defective stuff, and it seems advisable to keep the cut correspondingly a little below rather than above that worked out by the above calculations. o. Whether, in this plan of Regulation, the figure of twenty- five million per year or thirty-two million is used, is not of very great consequence. In any case the cut should follow the plan faithfully, and if it does, there is little danger of serious overcut. But this plan must never continue longer than forty years without some revision, a new inventory, a new sttidy of the situation. p. When once the larger part of this property is accessible by roads and railways, so that the selection method can give way to clear cutting, regulation may well divide this large forest into several working sections, and certainly cut out the timberline country as a permanent selection forest. Then also, regulation of accessible portions should change from any one of the above forms to an Area Allotment based on the forty acre tract subdivision of the forest. With this, there must also come development of well planned cutting series, preferably of a single lot in level country and on easy slopes, but of lots to fit topography in all steeper and more broken country. Injury from wind and snow in Lodge Tole as well as great danger from fire will recommend these independent stands. 5. Regulation in Western Yellow Pine. The property here considered had about the following condi- tions in 1972. a. Area: Nearly one million acres. Topography: plateau and easy slopes prevail, average altitude 4500. Site: climate, moderate; rainfall about 30’. Snow deep, over three feet ; 100 days sleighing ; summers warm and dry. Soil, mostly deep, pumice sands, quite fertile. b. Timber: largely in even age (all-old) stands; much over- ripe stuff “‘spike top.”” Only about 20,000 acres of young stands on lands, cut over in last forty years. Growth: the Ioo year tree is normally about 18” d. b. h. and 100 feet in height for dominant stuff. Fully stocked mature stands: 168 FOREST REGUI,ATION 40,000 feet on good site, and estimated 30,000 feet for average site. of property. Net growth is zero, probably negative. c. Preliminary Cruise only. According to this, the property has about eleven billion feet b. m. of merchantable stuff or about 12,000 feet average per acre, over fourteen inches d. b. h.; timber large, 5-6 logs per tree, and 2.6 logs per M. ft.; cuts very sound: timber long lived; natural rotation over 250 years. d. Market just beginning in its development. Only market for saw timber, preferably large stuff. Can well afford to take as little as 4 M. ft. per acre, i. e., it pays to log for this amount. e. Danger from insects, bark beetle in o'd stuff and also from fire: many lightning fires here. f. Plan of cutting so far: Clear Cut, with few seed trees; expect to bring up the cut to over one hundred million feet per year within five years. e. In making the preliminary plans the following questions arose : 1. I£ one hundred million feet are cut vearly on clear cut plan, it will take over 8000 acres per vear. If these cuttings range them- selves side hy side twenty years’ work will clear a solid area of about 160,009 acres, which will, or is expected to grow up to young stands of pine. Such an area of voung pine would be a certain loss in case of fire. 2. If one hundred million feet are cut in this way, it will take over 100 years to cover the property. In this time a great deal of the more remote timber wil! have died and hecome a total loss. Part of this loss is unavoidable, but may be lessened by a more speedy cutting over of the entire property. h. Suggested Plan of Regulation: 1. Cut on selection plan to allow free hand to purchasers to select areas; cut only 30-35% of total; cut clear only in exceptional cases and in areas no larger than necessary to remove clumps of defective, over ripe stuff unable to hold over for another cut. 2. Raise the cut as fast as possible to that indicated by the growth, the growing stock now on the ground, and a rotation of 120 years, this latter assumed long enough to produce saw timber of suttable size.

Denominator a is made only fifty years because there is no large gap in age classes here as in the Lodge Pole case cited before, and fifty years seemed quite sufficient to spread the small surplus, es- pecially in view of the fact that a considerable amount of large select stuff is rapidly becoming spike top and “going back.” 6. Modified Fixed Yearly Cut. Since it appears desirable to cut on selection plan and cut the property over as rapidly as pos- sible to avoid loss of large, old stuff, the attempt is made to cut over in twenty-five years, or about 40,000 acres per year. Taking not over 30% of total, about 4.5 M. ft. per acre the cut per year is: 4.5 M. xX 40,000-= 180 million ft. Here, as in the * Calculation of growth and growing stock in feet board measure always involves a certain apparent fallacy. In speaking of the average growth of ripe timber per acre, the stand 10, or 20 years old is also included, though, of course, there is no material here as yet to make any sawed stuff of any kind. 170 FOREST REGULATION Lodge Pole case, it is not possible to plan the fixed yearly cut for the whole twenty-five year period. Selection of areas and order of their cutting are determined by the purchasers, more than by the forester. But the plan is now clear, the forester knows that he should make efforts to bring up the cut to 40,000 acres per year, cut on selection plan, take about a third of the stuff and sell about 180 million feet. It is a safe plan to follow, it has a basis in the Growing stock and growth of the forest as determined by species and site, and as meas- ured and known. i. On this property of Western Yellow Pine with its good sites and rapid growth silviculture will probably abandon the Selec- tion Method after the first cutting over. In this case, by that time there should be a complete division of the forest on the ground and a reliable inventory so that Regulation can at once go to a regular Area Allotment. Here again, it is desirable if not necessary, that the large property be divided into several Working Sections, merely by reason of size. A million acre forest will prove unwieldly as soon as the markets make good forestry, in keeping with species and sites, a practical enterprise. The foregoing will suffice to illustrate what is attempted in Regulation of the cut, how the methods apply, and the good that is accomplished. It is clear that in our large Wild Woods properties it is not a matter of nice accuracy, Regulation can only secure a fairly reasonable figure, safely based on actual conditions of the forest and applicahle under present conditions of market and means of transportation. It is also evident that Regulation is adapted to the methods of silviculture, that in the beginning with Selection Method, a simple Area Regulation, a Modified Fixed Yearly Cut with Volume check based upon Return and Rotation, and calculated by Von Mantel's formula is quite satisfactory. Also that simple Volume Regulation, whether based on Von Mantel or the Austrian Formula, tends to an Area Regulation in time. As stated repeatedly, Regulation of the cut tends toward Area Allotment, full or restricted, as soon as a more intensive silviculture is made possible by a more complete and dependable utilization. In all cases this Regulation of the Cut in Volume performs only one part of Regulation and does not replace Division of the Forest and proper distribution of Age Classes. FOREST IMPROVEMENTS I71I G. GENERAL PLAN OF IMPROVEMENTS. In every forest property there is need for roads, trails and tele- phones, and in many cases for other improvements to make the forest accessible and enable various kinds of work to be done with expedition and economy. It is chiefly Silviculture, Protection, and Utilization which make necessary these improvements and plans for them miust take into consideration these three most important objects. In addition to these greater improvements necessary in the raising and removal of timber, or the principal crop, there is also need of suitable housing of men, of special means to assist in pro- tection. such as look-out stations, stores of supplies and tools; and on many of the large forest properties, both East and West, im- provements are needed to facilitate various lines of secondary utilization, such as grazing, utilization of resin, tanbark, seeds, maple sap, etc. Housing of men, and animals, most of the special provisions for protection and utilization are matters of detail plan and belong more in the sphere of forest administration than that of regulation. In a new country and on very large properties, however, the import- ance of a general policy concerning improvements is sufficient to necessitate its embodiment in every complete working plan. a. Roads in all forest pronerties serve three functions: they make the forest accessible, and enable transportation of material and timber into and out of the forest. They connect different parts of the forest itself and facilitate work, especially protection. Thev enable general travel through or across the forest. The relative importance of these three functions varies with locality and top- ography. In the Lakes Region or the South, a forest of one town- ship, located between settlements, makes the function of general trave] nearly as important as that of facilitating logging and other work. In parts of the Rockies, Sierra and Cascades, topography determines the location of every important road, and comparatively few roads can serve more than the one purpose of getting in and out of the forest. Between these extremes, many intermediate situa- tions occur. t. ‘The plan and development of the road-system is usually dominated by utilization, and the removal of timber sets definite 172 FOREST REGULATION requirements as to location of road, grade and construction. [ut in mountain countries a portion of the roads may be free from these requirements, and may serve merely for general travel and to connect different parts of the forest. It is a common thing to locate roads in the Rockies and other mountain districts on top of ridges to insure easier travel, especially less trouble with snow, though, of course, such stretches of road may not be of any use in hauling logs. In new districts, where present methods of logging do not call for ordinary roads, but must resort to special means, railways, slides, chutes, flumes, etc., and where the expense of regular road construction is great and but little justified as yet, this tendency toward building a system of roads primarily for general travel and accessibility will continue and influence the general plan. In level and ordinary rolling country the roads should be plan- ned for effective and economic utilization. 2. In the general plan of development of a system of roads in a new district there is a choice of procedure. We may adopt a general policy regarding the rate of development of roads. and general rules for detail location, grade and construction and then build as we need. Or else, we may plan a definite system based on reliable maps, studied in the field, and finally located on a special “road map” as “proposed” road svstem, to be built as time and money allow, and as necessity arises. This latter method will prove best. The development of roads piece-meal and haphazard, building wherever there seems need for it, and adding without plan, has cost millions in the old world. where hundreds of miles of highways have been abandoned, and relocated, and it has cost millions in our country, in railway development alone. That the making of this general plan is important and should fall to competent, experienced men is self evident. Mistakes in this work are costly and in most cases later changes are made reluctantly. 3. To plan a road system with a view to serving also in proper division of the forest is adding an unnecessary complication. Divi- sion of the forest should and naturally will use the roads as far as convenient, but the roads have their own definite functions and should be built for these and these only. 4 The General Plan for a road system for any given property naturally must depend on conditions of the property itself, and but ROADS AND TRALLS 173 few general principles can be laid down for its development. On a property of Michigan cut over lands with practically nothing to haul, uncertain reproduction and slow growth, the matter of roads may well le deferred. In an Adirondack forest park where money is supplied and where the object is to make the forest accessible for pleasure, a system of good macadam roads is appropriate and ad- visable ; it will pay. In a well timbered property in the South where logging goes per railway, a set of fire lines, merely kept open for accessibility may ‘be all that is necessary for some years. Practically the same applies in a large part of our western mountain forests. The basis for a road system is profitable use; there must be something to haul and the road must make hauling more effective and economical. Generally the value of a road system as part of development of a forest property has been underrated. And this is as true of the forests of the old world as of cur own country. Thousands of acres of forest in the Tyrol, in the Southern Alps of France are, todav, inaccessible and have practically no income. In the Great Lakes District conditions for years have been such that the putting back on the land of one dollar per acre would have developed a road system, and with it a forest division and protection and closer utilization which would have made these forest properties into well- paving business enterprises and would have changed the attitude of the people toward them, and resulted in more satisfactory taxation and protection. The same is true in part of the Southern Pinery. Here a rapid growth, easy and cheap logging and proximity to market are sure to develop a most intensive practice with regular thinnings and artificial reproduction. If some of the income in cut- ting the virgin stand is put back on the land in reproduction and roads, the property is ready for continuous intensive work. With- out this development of the roads, there is either long delay in proper income or else a sudden demand for large sums for roads; both unsatisfactory. The same principles apply evervwhere; good site, rapid growth and fair topography will justify road-development; poor, cold or dry sites, hox canyons, rockslide and cliff situations for long dis- tances, necessarily hinder. In more remote and difficult situations it is often better to defer building roads and get on with trails. In this case it is of value to locate the trail at once on a wagon road grade, and allow the trail to develop into a road if need be. 174 FOREST REGULATION 5. In actual location of roads on a forest property topography rules; the loaded wagon or sleigh should not go uphill. Valley and ridge in the mountains, with parallels to cut large slopes, form the chief features here; while in level and rolling country great choice of location exists, and a net work of roads may be suited entirely to the needs of the forest. ‘The grade is important, the worst piece in the road is a measure of its usefulness. Practicability of using the road for as many days each year as possible, and ease of maintenance are matters for the general plan to consider. 6. Here also should be mentioned the matter of co-operation between the owner of the forest and local authorities, neighboring owners of forest lands, mining companies and other people interested in the highways of the district. The possibility of creating favorable public sentiment by means of road-construction is worthy of con- sideration and liberal treatment. bh. Trails are an improvement required primarily in mountain countries where they replace the road for travel on foot and horse. But with forest division, trails along division lines of lots and sub- lots, etc., the foot-path or trail is likely to gain importance even in level country. In the case of trails as with roads the preparation of a general plan based on maps deserves preference over the build-as- you-need, haphazard way of developing the system. As stated hefore many trails may as well be located on regular wagon road grade and bridge over to the more satisfactory and permanent form of communication. c. The Telephone in forestry is an innovation; it is just be- ginning to find its way. into the European forest and is much less used there than in the United States. It is helpful in all kinds of work, but is especially needed in fire protection. Like trail and road it costs considerable money to build and costs every year for maintenance through decay of poles, breakage of wire, etc. Being most needed in protection, it is this line of work which dominates the planning of a satisfactory system of lines, and urges their con- struction, almost regardless of the general development or condition of the property. As with trails and roads, there should be a general plan, in which connection of different parts of the forest (ranger stations) with each other and with headquarters are most important. FOREST IMPROVEMENTS 175 d. Houses, barns, and pastures needed in the care of the forest property ; look-out towers or special improvements for protection, and the building of fences in grazing administration are usually provided as development of the property requires. For this reason the general plan can do little beyond stating the policy to be pursued. Questions here to discuss and answer may be as follows: should permanent headquarters be built, or should men be merely camped in tents, etc.; do the conditions of topography warrant and demand permanent look-out towers with regular man and telephone or is it enough to build trails to certain high points and require the local patrol to visit these? Is the grazing on this property important enough to warrant any improvements and development, or is it to be treated as temporary, and discouraged and discontinued as soon as possible? If grazing is to be permanent and valuable, should pastures, drift fences, corrals, etc., be built and should this be left to stockman or owner of forest? etc. Most of these improvements for administration and secondary utilization are not expensive, a mistake is not serious, and is readily remedied. Whether a ranger station is placed at the best possible place or not, is not serious, the whole affair only costs a few hun- dred, and can be replaced anvwhere on a month’s notice. H. PLANS OF UTILIZATION. Regulation of the Cut merely states the areas to cut and the amount of timber produced on the forest which may be taken from this every year without danger of injury, and does not concern itself with methods of logging or utilization. For this reason a separate plan is necessary. 1. Cutting Timber. In the German forest the cutting of tim- ber in State forests is done by the State itself. The forester makes contracts with individuals or groups, to cut, or cut and skid to the nearby road timber on a given area at a price agreed upon, always per cubic measure. ‘This keeps the logging entirely in the hands of the forester, and he insists on methods which do the least injury. In the United States the ordinary timber owner is also lumberman and logs as well as manufactures. He also has the entire situation in his 176 FOREST REGULATION own hands, to do as he prefers. Lut there are also a large number of owners who sell timber on the stump. In these cases logger and owner of the forest have entirely different interests; the former wants cheap logs and refuses to do anything which costs extra money ; and the owner would like to have the logging do the least injury to the remaining forest, and asks for considerable extra work and outlay. This leads to elaborate contracts, necessitates constant supervision and often ends in difficulties. What the development is to be in the Linited States to remedy this situation is not certain, but in all cases where a reasonably intensive forest management is warranted, sale of stumpage should be avoided, and logs or wood delivered at the road by someone entirely under control of the forest owner, This introduces necessity of planning and deciding upon general policy, as contract logging, or logging by owner ; proper methods of logging, such as machine logging, loging per sleigh haul, all year logging : and logging for particular goods, railroad ties, mine timber, saw logs, cordwood, etc. Thes are matters of great importance and deserve attention in the General Plan. Here also belong considera- tions of secondary utilization, such as grazing, turpentine, tanbark business, etc. 2. Grazing. Here the General Plan should state clearly op- portunity for grazing, the importance of this to owner and com- munity ; effect on forest and general methods to follow if grazing is allowed. In the Hardwood forest of Northern Michigan there is little opportunity and still less demand and grazing need not be con- sidered. In the Southern Pinery there is little and poor feed, great insect pest, poor grazing, but there is considerable demand, and for a time at least, this must be reckoned with. In the Rocky Mountain Districts over half of all large forest properties offer considerable opportunity for grazing and generally demand for this range far exceeds supply. Generally it is true, and yet rather unfortunate that opportunity for grazing in forest properties in- creases with dry climate and high elevation, the very things which make silviculture and the very existence of the forest difficult. Since the effect of all grazing is more or less inimical to forest growth, need for a close supervision and careful regulation increases, PLAN OF UTILIZATION 177 usually, with opportunity for grazing. All kinds of stock injure brush and tree growth, they hurt the small seedling most, trample and tear them out; they browse, on hardwoods more than conifers ; they rub, bark, and break all kinds. This damage is overrated by the European forester who has, for centuries, had to fight to keep any forest cover at all in nearly all densely populated portions. The danger is much underrated by the farmer and stockman and by most people in the United States. ‘The damage is greater with close herding as is practiced with sheep, and in general, can be modified very materially by proper methods of handling. In many of the forest properties of the West, there exist large areas of grass and brush lands which have been in this non-forested condition for centuries and the likelihood is that difficulties of re- forestation, slow growth, and remote inaccessible location will tend to keep these areas in such condition for many years more. Here grazing is the only proper use of the lands. In many cases grazing assists the forester by the removal of an inflammable grass cover by keeping interested people scattered over these areas during the danger season, and by tearing up the top soil and trampling in the seed of trees. In these western mountain forests grazing is generally restricted to summer season, average about 100 days, involves mostly sheep and cattle, to a small extent goats and horses, the latter both destructive stock. Capacity of the range varies within wide limits, averages in our western mountains and under present conditions about one head of sheep to four acres of land for the 100 days, or about twenty-five sheep rations per acre. Five sheep are set equiva- lent to one head of cattle. The income from this industry, about 3-5 cts. per acre and season, is very small, and use of the land for this purpose is advis- able only as long as a good forest can not be established or main- tained. In planning for the proper method of handling this business several important points arise: the relation of forest owner and local people demands that neighboring stock owners receive prefer- ence, that small owners be treated fairly and that each stockman has assurance of his range. Safety of range and forest demand that each man be allotted his own separate range, that he be given the same one for a number of years, so that he becomes interested in the 178 FOREST REGULATION maintenance and improvement of this range and can properly be held responsible. The General Grazing Plan requires at least a preliminary ex- amination of property and usually is based itself on the conditions met with as they have existed for years past. A reliable determina- tion of carrying capacity is difficult, and requires thorough scientific training ; all efforts in this direction by the stockman have furnished no results, his practice has led to devastation and general reduction of range capacity. 3. Resin industry, or “Naval Stores Industry”. This is re- stricted in the United States to the Southern Pinery, and primarily to the forests of Longleaf Pine. Practice in the past has been to “tap” or “bleed” for three or four years, usually with the expecta- tion of logging the timber as soon thereafter as possible. A change from the destructive “boxing” to the “cup” method, permits of greater adaptation and a prolonged use of the tree for this purpose. ‘The future of this industry depends on cost of labor and the value of the resin products, chiefly turpentine, and this in turn on the possibility or probability of development of sthstitutes for turpen- tine and rosin. Assuming the value of resin to continue the question for the General Plan is first: should the forester develop special stands of timber with resin as the important product, or shall resin remain merely a biproduct in ordinary forestry? Again, should bleeding be restricted to mature stuff and be continued only for a few years, or should the stands be specially started (wide spacing) and heavily thinned to enable use of part of the thinnings, and also permit of a prolonged use of the mature stand for bleeding, by proper care and rotation? In regulation, in development of proper age classes and especially in ‘distribution of age classes, or proper mixing of old and young stands over the property and then also in establishment of independent woods or cutting series, the resin industry needs consideration, for stands of timber in process of tapping are in an unsafe condition and a menace to surrounding timber on account of fire as well as insects, notably bark heetles. Regukation should keep each stand in such a condition that, in case of trouble, it may at once be removed and trouble checked with the least danger to the surrounding stands. PLAN IN RESIN INDUSTRY 179 Regulation through proper age classes and a suitable area allot- ment should provide a continuous supply of resin, in keeping with size and condition of forest. 1f bleeding takes only the stands and trees to be logged in the near future, Regulation for the Resin Industry simply runs four years ahead of that of the cut. But in this case a definite area regulation becomes necessary, stands to be tapped must be picked out at least five years before logging, bled for four years and then turned over to logging. An area allotment for ten years, revised every five years will answer very well; to prepare for long periods ahead is neither necessary nor advisable, since uncertainties in the resin industry, dangers from fire, insect and windfall are very great. If the Selection Method is used, area allot- ment takes on the form of modified fixed yearly cut as outlined above, and tapping is restricted to trees to be marked for cutting. For this reason resin work should be preceded by a regular mark- ing, which will avoid confusion when the trees are to be boxed or gotten ready for cup and gutter. As regards the method of utilization of resin, the conditions resemble those met in timber cutting; it may be done by the owner through day labor or contract, or else it may be sold on the stump. Experience would indicate that this latter in the resin industry is even less satisfactory and more dangerous to the forest than is the selling of timber on the stump. 4. Tan Bark and tan extract industry allies itself so closely with the cutting of timber that little additional need be said. In many cases, however, this is not true and the value of this industry may even influence choice of species to raise and method of silvicul- ture to employ. In Oak coppice the entire plan is often based on harvest of bark, and in Chestnut stands utilization of the timber itself is modi- fied, the wood is ground and tan extract supplies the chief income. Other secondary forms of utilization of the forest property exist in different localities, and under various circumstances. Ordi- narily their importance, income, permanence, etc., determine whether it is necessary to consider them in the General Plan, and the few illustrations cited will indicate their treatment. 180 FOREST REGULATION I. GENERAL PLAN OF PROTECTION. Protection against fire and trespass is one of the most important tasks of the forester. AAs soon as any effort at forestry or even ordinary care of property is attempted, effective fire-protection de- mands attention. And it must be a protection which protects, and protects all growth, and not one of the “light burning” type, where reproduction and young growth is wilfully destroyed by fire to save a few saw logs, a criminal practice occasionally recommended in our country.* Protection of the forest against insects, which in the last fifteen years has cost several millions in the United States has always been one of the standing duties of the European forester, and of late even the fight against wood-destroying fungi has been added to his work. Lut both, insects and fungi, are too irregular in their occurrence, and the methods to combat the evil have not been suff- ciently developed to warrant making these lines of protection part of the regular program or Working Plans, and the matter so far has been left to special effort and therefore to special Plans. Since patrol sufficient for fire protection is usually ample to avoid all serious trespass and vandalism, consideration of forest protection in the General Plan narrows down to measures for fire protection. These considerations involve a study of the property to determine the degree of danger, dangerous areas, stands of timber most deserving protection, climate and fire seasons, sources of fire, human element in this, topography and accessibility from the stand- point of fire protection, the methods best suited, as well as all the available means to prevent and combat the danger, including co+ operation of public authorities, neighboring forest owners and the people of the district. The degree of fire danger varies within wide limits not only for different parts of the country with different climates and forests, but also on the same forest property itself. Dense stands of old timber are most immune, dense stands of sapling conifers 5-20 feet in height are in greatest danger of taking fire and are almost certain * This practice is old in the Southern Pinery; has always formed part of the protection of Turpentine orchards, and was carried to the Western forests and recommended particularly for the forests of Yellow Pine and Sugar Pine by some of the prominent lumbermen. PLAN OF FIRE PROTECTION 181 loss and total loss if fire once starts. Cut over lands are fire traps, both in hardwoods and pinery; hardwoods are not as easily destroyed as conifers, but the leaf mulch under hardwoods, in dry years, 1s often worse than the soil cover in conifers, etc. Forests in the Lake Region and Canada, and also those of the Rockies have suffered more and are in more serious danger than those of the South. Dry spells in early spring and again in the fall after frost, but particularly the specially dry seasons which recur every 8-12 years in the North and West have made enormous forest fires possible, where literally millions of acres of land were overrun. In mountains, particularly the Rockies and the East side of the Pacific Ranges, the South slope (exposure to South) is dry, brushy or bare and fires start easily; the North slope is well wooded, cool and damp, and much safer. When sufficiently dry, however, it is just these well wooded slopes which make the most terrific fires and involve the greatest money loss, a fact also experienced in stands of giant timber on the coast where usually a wet climate gives the im- pression of great safety. In all mountain property, effect of topography must he con- sidered ; fire runs rapidly up the slope, it descends slowly, it creates great draft in all narrow valleys, and it is harder to get to and fight, but generally easier to discover in mountains than in flat lands. The temptation is to protect valuable stands and neglect the less valuable. This is commonly a mistake, the fires gain headway in the unprotected woods and then spread irresistibly over the valu- able forests in spite of all effort of protection. Means of fire protection in the forest consist chiefly of: patrol, equipment and outside help. Since the proverbial ounce of preven- - tion is the chief object, Europe has always relied on patrol, together with ample paths and roads to make and keep the woods accessible. In the United States patrol has generally been neglected and even at present there are practically no large forest properties with a patrol in any sense adequate to the task. European experience indi- cates that an area of over 5000 acres to one man on foot is too large, that genrally not more than 2009-3000 acres should he watched over by one guard. To make up for lack of help, the foresters in the United States have developed equipment, particularly telephone, and look-out 182 FOREST REGULATION stations, etc., and have endeavored to supply with excellent organiza- tion what they lack in numbers. (rganization of outside help is necessary since patrol service is never, in any forest, sufficient to fight fires, and is especially needed in their regular work during a time when large fires are burning on parts of the property. This organization usually con- sists of definite arrangements with stores, etc., for supplies, pro- visions, tools, and for help; and also involves the arrangement of paid for, or gratis co-operation with the people of the district, by which they agree to watch, prevent and fight fires, whether ordered or not. ‘lo serve its purpose, the Plan should outline an organiza- tion such that any fire is detected within one hour and is reached not later than within two hours from the time smoke rises above the timber. For some years lack of funds may prevent a full develop- ment, but the plan should fully recite conditions and clearly show what is needed, and then make the best distribution of the means at hand. -\ common mistake which has been made in forest protection has been an effort to economize and get on with a sort of half pro- tection. In the Great Lakes Region this has been worse than no protection at all, for it has merely led to contempt on one side and discouragement on the other. Ten years of strict protection would have made further protection easy and much less expensive. K. GENERAL ESTIMATES OF INCOME AND EXPENSE. Estimates both of income and expense are usually stated under the different topics dealt with in General Plans of Utilization, Silvi- culture, etc., and are stated more in detail in Detail Plans. Never- theless it is of value to bring these together and state in lump sums for the various important items what incomes and expenses may he expected each year for at least a few years in advance, and supply this important information to the owner, as well as a guide to the forester. The figures should he based strictly on what is practical and expected to be done, but there should be, in new enterprises, a few statements foreshadowing what may be expected in the near future, and the desirable, as well as the actual should be indicated. GENERAL ESTIMATES 183 In using this general estimate and apportionment it is neces- sary to avoid too great rigidity, for it is to be expected that all estimates will be modified to suit changed conditions. With this Estimate of Income and Expenses may well go a plan of organization or personnel necessary in care of the property, and here as in apportionment of funds, there should be a statement ex- plaining what is really needed for best results, as well as a list of men which may actually be employed under present conditions. From the foregoing it is evident that the General Plan is neces- sary for any intelligent, business-like work on a large forest prop- erty, and that this General Plan or Plans require considerable infor- mation for satisfactory basis. From this it follows that different parts of the Plan will differ in value, and that different parts will be worked out and improved more or less independently, but also that their interdependence is so great that a careful correlation is neces- sary. It is clear, too, that in our new enterprises, where forest administration starts with very little exact information regarding the property, these plans are only tentative at first and require revisions as fast as information is gathered. Experience in the United States shows that, at first, these General Plans need modi- fication every year, and take on the appearance of the Detail Plans to be discussed, and that commonly the line between these two practically disappears. This condition will not continue; as soon as information is ample and reliable, and as fast as conditions of mar- ket and transportation take on a more settled form, the General Plans become more and more definite and permanent. DETAIL PLANS. The Detail Plans take up various lines of work on the forest as outlined in the General Plans, and also various less important tasks, coming up in administration of the property. These plans, usually in tabular form, state exactly what is to be done during the coming year, or few years, enumerating the particular forties to cut, various sales under way, men holding grazing, etc., permits, number of stock of each, etc. These plans then tell the forester what to do now, where to work, and in silviculture, etc., the method to follow. 184 FOREST REGULATION These Detail Plans differ from the General Plans; they do not dis- cuss the conditions and reasons for doing, establish no policies, merely outline an orderly execution. The number of Detail Plans is not fixed, it varies with the nature of the property and lines of work in hand, so that it may vary from vear to year even on the same property. The following will suggest treatment of the topics in these plans: 1. Plan of Organization of Help. ‘This is a brief tabular statement, practically a list of the various men employed on the forest,their names, date of employment, salary, station, and principal task. [Extra help, such as labor in building roads, etc., is not enumerated. ‘The summation presents cost of regular organization. 2. Detail Plan of Protection. Applies onlv to one particular vear. It enumerates: money allowed for protection; name and number of regular men available, number or name of district and area of country which each man covers, extra help for each district, where stationed, for what period employed, and at what salary. Telephone lines in each district, location of these and connec- tions, look-out stations with special men, connections and district covered; this latter hest stated by Protection Plan Map. Number and location of stores or “caches” of tools and other supplies. Name, location, phone number, etc., of persons at stores, farms, etc., with whom arrangements have been made as to supplies, transportation and help; important points of arrangements made. Name and location of persons engaged to assist in paid or unpaid co-operation. A map as part of Plan of Protection, showing topography. roads, and trails, Ranger and Guard stations, look-outs and their effective range; ranches, hamlets and the number of men and teams available at each. The Detail Plan usually recites these items for the entire forest and also for each protective district. It should also add the import- ant points in instructions so that each person knows what to do, to whom to report, where to call for help. In these instructions the authority to incur expenses should he clearly indicated. PLAN OF IMPROVEMENT 185 The above outline patterns after present plans on some of the large Western mountain forests and is far more elaborate than is necessary on a forest property of ordinary size and character. 3. Detail Plan of Improvement. Here. as in protection, tabular statement should be accompanied by an Improvement Map. ‘This should show existing and planned improvement in different colors; it may well show old existing im- provements, those built in last five years; those proposed by the General Plan and those suggested for the coming year. The tabular statement states the apportionment of money. total and sum for each class. It enumerates each project, piece of road or trail, piece of telephone line, house, barn, bridge, line of fence and gives location, dimensions, character and cost. In roads and trails, length, width, quality, estimated cost; in telephone lines, the kind of support, weight of wire, cost of material and of labor, etc. In case of roads, trails and telephone lines a detail or special. map, indicating location of all points of special difficulty, rock, swamp, canyon, bridge, etc., and also specifications for materials should accompany the tabular statement. For houses, barns, etc., a plan and set of specifications with estimate for cost of material and labor should be attached. The following simple suggestion may serve to illustrate : Deram, PLAN or IMPROVEMEN'S FOR IQI4.

In the European Forest where the forester cuts whatever timber is ripe, according to his plan, and harvests his crop exactly as the farmer does, regardless of any buyers or applicants, the Detail Plan is based on the General Plan of Regulating the Cut and commonly takes ahout the following form. Detain Plan or Currinc FoR YEARS 1914-1918. Loca- Estimate Amount.

In the United States especially on large remote properties where all utilization of timber must wait until there is application, or market for this timber, the above plan of simply declaring certain areas to be ripe timber and assigning them for cutting during next vear, or next five years, needs modification. Jn these cases the PLAN OF UTILIZATION 187 detail plan starts with the “timber sale” actually consumated. Lut in these cases, too, it is almost a necessity to have a convenient record or tabular statement which shows to the forester and owner at any time, the exact status of utilization. This statement takes the place of the above form of detail plan. Where quite a number of sales are in progress, the following form has been found very convenient. It divides the information into three parts: a. .A simple and brief table which serves as the Detail Plan proper. b. :\ map or township plat on which the sales are indicated, to go with the above table. c. -\ separate table for each sale, to file with the particular sale case, contract, scale records, etc. The tabular plan (a) gives the following information: number of sale, name and address of purchaser, location of timber, amount of timber, kind and price of timber, date of contract, date when closed, amount of timber cut under this contract and value of timber. Where a sale goes over to another vear, the number is kept, and the record shows the cut and income for the vear. .\ new table is pre- pared each year. The sheet to go with the sale case itself may well take approxi- mately the old form of the detail plan of cutting. It should enumer- ate the lots or areas to ke cut, the estimate for each, the method of silviculture, the date (month) when any particular tract is finished and the total cut from this tract. This plan of cutting in a particular sale can take about the fol- lowing form: Sale No. 17. Name of purchaser: John Doe. Address: Doeville. Amount of sales: 150 million ft. b. m. Date of contract: Sept. 10, 1913. Life of contract: 15 vears. Silvicultural method, or rules for marking the timber: selection method taking only stuff over 16” d. b. h., defective or sound ; leav- ing generally 60% of total volume of the stand, and cutting clear 188 FOREST REGULATION only in small spots (not over three acres), exceptions to this in cases of stands of very defective stuff.

Etc., etc., etc. It adds materially to the convenience and usefulness of these plans to provide space where the execution of the work may be noted and combine the plan of work with record of execution. Since these special plans usually develop printed forms for their record, there is great danger, as in all book-keeping, to trv to do too many things on the same sheet. In a field sheet this is a virtue, in a plan and in book-keeping it is usually a fault. ‘Ihere is also danger of developing too many plans and records, starting series of records about trivial things. Usually these unnecessary things soon become irksome and are abandoned and much Jahor and time is wasted. *In place of the awkward description of: N. E. 4% of S. W. %, a simple numbering plan will prove much more convenient and prevent many mistakes. DETAIL PLANS 189 5. Detail Plans of Secondary Utilization. Merely for illustration the grazing and resin industries are mentioned. a. Grazing Plan for the Year. This should be a table show- ing: Total number of animals that will be allowed on the property, preferably by the two kinds, cattle and sheep. Then a list of persons puchasing range, with name, address. Ikind and number of head of stock, district and area assigned, number actually counted in, and money actually received. Time when stock may enter and when it must leave the range may be stated at top of table, if all fare alike, otherwise with each pur- chaser. Here as in the timber sale, a right hand page with space to record the experience had with the range and stock of each purchaser will easily develop a valuable record for use in future planning. -\ map indicating areas assigned to each person or group of persons, and also the driveways for stock into and- across the property together with all improvements important in grazing is helpful. This outline applies only to very large properties such as the National Forests. Lut even on smaller holdings (10,000 acres) any enterprise like grazing needs regulation and orderly conduct if it is to continue without becoming destructive to the forest. Mat- ters of range study and experiments for betterment are best treated under separate head. b. Resin Industry. Ina forest of Longleaf Pine, under ordi- nary conditions the Detail Plan of utilizing the resin consists of a list of the lands covered by “turpentine orchards” or wnder opera- tion, and a map or set of plats presenting the same information graphically. It is convenient to separate areas bled for the first time (new orchards), those bled one, two and three years. The General Plan should decide on method (box or cup) and number of years any tree is to be tapped and whether the work is to be restricted to a few years preceding the logging of the timber, etc. It also assigns, on this basis, stands fit for bleeding for the next ten vears. The detail plan selects and lists the stands to be tapped in about the following manner: 190 FOREST REGULATION “Crops” STARTED 1914. Crop Location. Area.| No. of ia of resin Conditions and or years. : No. Bece| Tat, Acres.] Boxes experience.

Since this same sheet is used for all four years of the life of these “crops”, it should provide ample space. With the old method of about 200 acres per crop of 10,000 boxes and about 4000 acres for one still, the plans for even a large property (50,000 acres) would not be many. The detail plan keeps the situation clearly before the forester, it shows the execution of the general plan, and furnishes a record of work and results. Where the resin is sold on the stump the matter of detail plans is more complicated, and may well follow the plans suggested under timber sales. 6. Detail Plan of Planting and Nursery Work. This is commonly a plan for several years (5), and in most cases it is convenient to keep separate the planting, nursery work and gathering of seed, if such is done. a. he Planting Plan, whatever the method (seeding or plant- ing) tabulates or lists lands to be covered, the method used, esti- mated cost and actual cost per acre and total. b. The Nursery Plan, preferably a yearly affair, states the amount and condition of stock on hand, number of beds to be started and transplants to establish in order to supply the demands set by the forest (for planting, etc.). It enumerates changes in area, and equipment, if any, and the estimated cost of material and labor for the year. c. Seed Gathering is not a vearly affair except with very large forest owners (state, national forests). It comes with seed years, (every 3-5 years) and then calls for special efforts and with this for special plans. Usually seed is bought (in the cone, etc.) from DETAIL PLANS 19I individuals and the enterprise merely calls for timely advertisement, instruction, arrangement for receiving and storing and after that, of extracting the seed, cleaning and suitable disposition, shipment, and storage. 7. Detail Plans of Surveys, and Special Studies. On any large forest property, if no more than 10,000 acres, the task of examining lands, estimating and describing stands, studying gowth and habits of the timber on the land, establishing and clearly marking the boundaries of the property, and its divisions is usually the work of a number of years. Much of this work can be planned to come when other work is not pressing and in any case it is desir- able that much or all of it be done by the forester in charge, since there is no way in which he gains the necessary familiarity with all parts of his forest in a shorter time or better way. For some years on all forests and for large properties always,. there is an annual task in survey work. On large properties this work deserves a place in the general plans, setting forth at what rate the forest should be covered and methods to be used. The detail plan, usually a yearly plan, enumerates the various projects, areas to be estimated and described, lines to be run or re-run, cleared and monumented. and detail studies for volume- and yield-tables to be made during the year. This is put in a tabular form with estimates of cost and a right hand space for record of work actually performed, results including expenses incurred. A map showing the progress of this work forms an important part of this plan. 8. Plans for Experimental Work. On very large properties the owners will often find it to their advantage to allow a reasonable sum to carry on work of an experi- mental order, rather than to trust altogether to information gathered elsewhere. In state and national forests the reason for such work is evident, and here it receives deserved attention. But there is nothing which needs careful planning, definite control and regular report of results more than experimental work. Plans for such tasks are detailed and special, they develop with demand for the information. The experiments now under way on the National 192 FOREST REGULATION forests, for betterment of range, study of growth under great variety of conditions, ete., will be worth millions to the Nation, but a large part of such experimental work can be done and carried to a satisfactory finish only through strong organization, with well digested plans and policies and with intelligent, watchful supervision. RECORDS OR BOOKKEEPING. There are probably few kinds of relatively simple business where a systematic record is more necessary than it is in the care of a forest property. .\ 100 acre stand of timber is quite a property in itself and yet in a forest even as small as the usual German revier, i. e., one of about 10,000 acres, it is only 14% of the total and may be a rather remote and very much hidden 1% at that. Ina large forest such a§ a National Forest, or the State Forest of New York or Pennsylvania, it forms often not more than 1/50 of one per cent, it is one stand in 5000; the forester may be in charge of this property for twenty years and never really see it, to go over it and appreciate its condition. The stand of timber, growth, thrift or lack of it, the work done, or needed, even a timber cut; any acci- dents, etc., etc., all may have been known and reported by the assistants at one time and another, but unless there is a systematic record kept, all these are forgotten, filed away and never seen again. This stand may be mature and need cutting, but unless there is proper record and plan, it may remain uncut for thirty years, and entail great loss to the owner. ‘That such things not only can but do happen, was brought out only a few years ago in the controversies in the legislature of Bavaria where is was shown that millions of feet of timber were left to stand unused, long after reaching proper maturity, simply by some process of neglect, where the responsible office practically forgot their existence and condition. The fact that a good working plan was made, many years ago, does not help this situation; a plan in itself does nothing, it takes systematic execution of this plan and in this execution an orderly record is a necessity. BOOK-KEEPING 193 The record or book-keeping in a forest business covers three parts: Property. Work. Results. a. Record of the Property. On every forest property this involves the following items, to which, in some cases, others may be added. 1. List of Lands. In Districts of the United States Public Lands Survey the forty acre lot forms a unit, the forties are ar- ranged by sections, township and range. The list not only gives the number or designation but also the actual area either by the United States records or, if corrected, by last accurate survey, since not all forties are forty acre lots. To this may be added whatever other information seems desirable; a note as to date of last survey is useful, last inspection of lines and monuments, and condition of these. In the older States without regular United States survey and then also in mountains, where the forester makes his own subdi- vision, the forty is replaced by the Jot, an area of regular or irregu- lar shape and size, and these lots grouped into blocks to correspond to the sections in regular survey, and therefore preferably not over 2000 acres in size. Civic township and county and even state may need to be noted. This List of Lands is accompanied by plats based on the original survey; or by a simple “Land Map” showing only areas, lines, their direction and length. 2. List of Houses, barns, cabins, camps, mills (small ones, if part of property), also fences, etc., with brief description, condition and present value. This list is accompanied bv a copy of the im- provement map. ; 3. List of Personal Property, teams, tools, ctc. A simple enumeration giving condition and value. 4. List of Roads, trails, telephone lines; name or number of each, location (best shown on map, but also stated here), kind, 194 FOREST REGULATION length, conditions, and present value per mile and total. This also is accompanied by an improvement map, or by special road and trail map. ‘The above four lists are corrected to date once every year. 5. Detail Report, or Detail Description of the forest by lots; with maps. Each lot receives at least two sheets, more if needed. On one of these sheets is recorded the full description of the lot, the land and stand, with estimates, etc., in the way that it is recorded in the field, i. e., same topics, same number of columns. On the other sheet is recorded any work, expense and income in connection with this lot, such as planting, thinning, etc., also every cut of timber, the amount and value taken, and in this way an accurate history of each lot is established and maintained. F:very log cut should be scaled as coming from its lot, and the totals of the scale report should be recorded on this lot sheet. If any part of the lot is planted, seeded, or fail parts of a plantation corrected, the year, the area, method, cost per acre, and total and the success (end of vear or two years) is noted. This record, on a large property, comprises hundreds of sheets, and is arranged hy sections or blocks. and townships, for con- venient use. The description part of this record in an older forest property is revised once every ten or twenty vears; in new enterprises it is corrected as opportunity offers; some of this is done every year. But in any case a complete working over of the property should occur at certain regular times, not over twenty years apart. When that is done, the old sheets are kept, and new ones added. 6. The General Report of the Property. This compilation, explained at length before, is filed separately for convenient use. Like the detail description, it is re-written at set times, but in new enterprises, it is modified, chiefly enlarged, every vear. The manner of filing these documents is a mechanical affair and is done to suit. Filing flat, with sheets standing in Manila folders is certainly as convenient as any way and in small enterprises the equipment for such a file need not be elaborate. Since the gathering of all information here enumerated, especially the detail description of the forest, costs a great deal of money, these documents should he copied and safe storage provided. BOOK-KEEPING 195 b. Record of the Work and Results. This record should accomplish the following : 1. The forester should know every day what work is being done on his forest, and this information should be on paper as well as in his head. 2. He should be able to report at set times, preferably once a month: What work has been accomplished. What expense has been incurred. How much material has been disposed of and what was the income. 3. The record should be brought up every month and be in such a form that the owner, inspector or any other interested person could see at any time, and without calculation, what was done dur- ing the past month, or months. 4. Records should show that the policy, general and detail plans under which the forester works, are actually and faithfully being followed. This record of work to do and work done includes: 1. General Plans, as above outlined. These are revised at regular intervals (ten or twenty years) and on new properties, are amplified every year. 2. Detailed Plans, as outlined and discussed. hese are re- vised every year. As stated above, in most detail plans, such as improvements, planting, utilization, there is space left at the right for the record of the work and results actually accomplished, indi- cating to what extent the plan has been followed and its projects completed. 3. Daily Record. This is a journal of work with estimated expenses, it states each day what the different men are doing, what projects are under way, the number of men on each, and probable expense. This daily record may also include any important obser- vations, meeting of men, important conversations, etc., although as a rule these observations, etc., are better kept in a small private pocketbook-diary, since it is not always desirable to have them open for inspection. 196 FOREST REGULATION 4.
