[No. i. A SUGGESTION FOR SECURING BETTER PROFESSIONAL TERMINOLOGY. By p. S. Lovejov. Most of our new words and phrases arise either by direct translation from another language in which they are already in use to express the identical idea, or, through the more or less gradual adaptation of words and phrases already in our own lan- guage. The first source is illustrated by our use of "working-plan" ; the second by "reconnaissance." Further terms originate by di- rect manufacture from established roots, as "silviculture" or "dendrology," or by new combinations of old words, as "lookout- station." It is usual for such professional words and terms' to differentiate as the profession develops so that their definition is different from time to time. Any new term is likely to become permanently grafted into our professional language and has rather great possibilities for use or abuse. An unfortunately adopted term may become very mischievous. If a term is short, easily spelled, self-defining, legitimate in derivation and accurate in significance, it is likely to be a good term. Our need for new terms and phrases is constant. The in- troduction and adoption of new terms is too easy: the results are often unhappy. An illustration of the perv^ersion of tenns is found in the current use of "woi king-section" and "working-circle." The use of the terms in Schlich is constant and consistent. Forest Ser- vice Bulletin 61, properly intended to be the official dictionary for professional terms, retains the terms but exactly reverses the definitions. This seems to have been a clerical error, but tlie 2 forestry Quarterly. recent literature of the Forest Service is apparently in the way of perpetuating the inadvertence. The term "working-section," as used by Schlich, seems to have been dropped entirely. The results are confusing and the situation would seem to be quite un- necessary. Another illustration of an unhappy term is "reconnaissance." When the word first came into use in the Forest Service it was legitimate and accurate even though clumsy, foreign, long and miserably easy to mis-spell. It signifies "preliminary survey" and had been used in this sense for many years. But the character of our forest surveys changed rapidly ; the use of the word was continued. It now signifies "the linear and topographic survey and mapping, estimating and reporting upon of forest lands." It often involves all sorts of further details of logging, grazing, alienations, soils, tree diseases and ecology. Much of this work is to-day of the most intensive and accurate kind and involves a very large degree of permanence. The inadequacy of the word early became evident and we have "jack-rabbit surveys" for the original "reconnaissance" and "intensive reconnaissance" for the rest. But why "reconnaissance" at all? By the word we mean "finding out what we have and where it is." That is "taking stock." Taking stock is "inventory." Why not say inventory when we mean just that? An objection against the use of "inventory" in this sense has been urged, to the efifect that "it smacks too much of common business." To some foresters this might not be an insuperable objection. This might also be said of the objection that "it would require the re-filing of pounds of correspondence and another circular letter." The phrase "germinative force" has recently been introduced to express a new measure of the rate of seed germination. The need of some such phrase would seem to be evident; but is the phrase wholly satisfactory? Certainly it is far from self-ex- planatory and the use of the word "force" is actually misleading. In order to use the new conception conveniently we need some form of abbreviation or numerical expression. We have to ex- press a per cent, of a per cent. What shall we call that? If the whole matter is not to be left to work itself out by in- dividual preference, accident and whim, there should be some representative professional body to pass upon all new terms and Securing Better Professional Terminology. 3 phrases. In the absence of such a body is it not likely that foresters in America will soon find themselves in a hopeless tan- gle of terminolog)' ? Ample precedence for such an experience can be found in many sciences and professions. Let us have a standing committee in the Society of American Foresters, the duties of which shall be somewhat as follow : (i) to consider and revise current terminology (2) to note or receive all new professional terms and phrases and to pass upon their suitability, recommending their adoption or rejection. (3 ) to recommend new or other terms for all terms rejected, if deemed desirable, (4) upon application, to consider and recommend terms for any conception deemed worthy of fixation in our profes- sional language. EDITOR S NOTK TO THE ABOVE ARTICLE. The Editor, having to handle the manuscripts of his contribu- tors, desires to express his full sympathy with the above proposi- tion. He is often filled with sadness at the lack of uniformity net only, but of linguistic sense in the choice of terms. There are any number of clumsy, misinterpreted, misunderstood terms which recur in the contributions to the Quarterly. He desires to recall his longer article in Vol. HI, p. 255, written more than eight years ago, when reviewing the U. S. Forest Service Bul- letin 61, which tried to establish a terminology. He there laid down some principles which may bear repetition in this connection. We hold that technical terms are merely conveniences for quick and precise speech and should be first of all tested by that object. To attain it, they should conform as much as prac- ticable to at least the following four requirements, important in order of their sequence: (a) A term should be necessary. As long as common lan- guage is sufficient to precisely state the idea, special terminology is superfluous, except, perhaps, for special cases or special writ- ings. A corollary is that, as long as an accepted term employed in other sciences or arts expresses precisely the conditions or ideas to be expressed, there is no gain in coining a new word. 4 Forestry Quarterly. (b) Words which are current with well established mean- ings should not be employed as terms in another sense, especially where it is likely that ambiguity would be introduced by the simultaneous use of the ordinary sense and the term meaning. (c) Age is a virtue: a long-established, sufficiently well de- fined and understood term should not be lightly discarded or supplanted unless very considerable improvement were gained. Convenience, we repeat, is the object of language, and it is more convenient to use established language than to fish for new words. (d) Terms should be as short and as nearly as possible self- explanatory. It is, of course, well nisfh impossible, nor is it necessary, that a term explain all that is implied in it: it is the very impossibility of doing so that leads to the use of special terms which to the initiated at once convey the full explanation. But, if the term suggests its own explanation, it will be the more acceptable. (e) Finally, the word or word combination should have a term-quality. This is, perhaps, the most difficult requirement to define or to discover: it is like taste in art, it requires a language sense which by instinct or intuitively rejects the un- suitable. A word infrequently used in common language has thereby more term-quality, than one in common use; a Roman word more than a Saxon ; a brief combination more than a long one ; a compound more than a phrase ; an unusual compound more than a common one. If the term fulfills all these conditions, it is perfect; by so much as it fails, it is deficient and open to criticism, calling for improvement. We may add, that there is a movement on foot to have a Committee of the Society of American Foresters revise the terminology — a most excellent proposition ! Such committee may then be made permanent or self -perpetuating. GRADED VOLUME TABLES FOR VERMONT HARDWOODS. By Irving W. Bailby, Harvard University, and Philip C. He.\ld, Harvard University. Approximately one half of the data upon which the following volume tables are based was secured by senior students of the Harvard Forest School in April and May, 1913. During this period the members of the class were engaged in mapping and estimatins^ the timber upon tht township of Somerset in south- ern \^ermont. The primary object in collecting material for graded tables was to focus the attention of the students upon local methods of logging, milling, and grading hardwoods, and to afford essential experience in studying the effects of such fluctuating factors as forest type, tree form, defect, method of utilization, etc., upon the graded yield of logs and trees. Al- though each student spent but three out of eight weeks in this type of preliminary training before undertaking the final task of estimating standing timber, much instructive and reliable in- formation was obtained. The facility with which material for graded volume tables could be collected made it seem advisable to secure sufficient additional data to justify the construction of tables for beech, hard maple, and yellow birch. With this plan in view one of the writers and Mr. George W. Kimball, M. F., spent the month of June, 1913, in the locality previously visited. Before passing to a detailed description of the results of this investigation it will be well perhaps to discuss briefly certain points that are significant in the construction and use of hard- wood log scales and volume tables. An elementary principle but one which is not always sufficiently emphasized is the theorem that no greater degree of refinement should be used in any detail of a problem than is justified by the homogeneity of the material and the accuracy of methods used in other phases of the problem. Of course the accuracy of these details should be properly correlated with the accuracy desired in 6 Forestry Quarterly. the results. For example, in the determination of the 'Modulus of Rupture' and 'Crushing Strength' of timber, values are read not infrequently to units or decimals. These figures are the averages of a large number of individual tests. Unfortunately, wood, like most organic matter, is an extremely variable material and dif- fers to a marked degree in different representatives of the same species and in different portions of the same tree. Fur- thermore the same piece of timber will vary greatly with changes' in its environment. Thus the 'Modulus of Rupture' or 'Crush- ing Strength' of a given kind of wood represents an average of many widely fluctuating values. As yet no satisfactory method has been discovered for determining, a priori, the variation of a given piece of timber from the normal or average strength values of its class or grade. Since a structure is in most cases de- pendent upon the strength of its weakest member the engineer and architect must allow for these fluctuations by the use of the so-called 'factor of safet}',' an approximate and arbitrary fig- ure. Therefore, elaborate methods of testing timbers, and values which record units or decimals are refinements that are not justi- fied except perhaps in theoretical researches when the investigator endeavors' by means of carefully selected small specimens to ana- lyze certain factors that produce variation in the strength of wood. In a similar manner the contents of logs and trees fluctuate greatly with variations in certain natural and economic factors' of which the most significant are form, defect, and methods ot logging, milling and utilization. Thus, log scales and volume tables, compilations of averages, are inherently inaccurate except when applied to more than a limited number of logs or trees. Furthermore, they are untrustworthy unless the natural and economic factors to which they are standardized are homologous with those which prevail in regions where they are applied, or unless accurate converting factors are available. The problem of successfully standardizing tables to given conditions and of using in each step of the process a justifiable degree of accuracy is a difficult undertaking. For, even in the case of homogeneous bodies of coniferous timber, volume is subject to considerable variation due to differences in method of logging, milling, and utilization; a point that has not always been sufficiently em- phasized in the construction and use of volume tables. Graded Volume Tables. y Hardwood timber is heterogeneous and extremely sensitive to fluctuations in the economic factors mentioned above. There- fore, it appears to be true that, until our methods of utilization are matured and become less plastic, 'general' volume tables based upon a large amount of data, collected from a wide area, cannot be applied in any given region with sufficient accuracy to justify the cost of their construction. If 'local' volume tables are to be employed it must be demonstrated that they can be compiled rapidly and inexpensively and that their use yields more reliable and accurate estimates than existing rule of thumb methods. For many reasons it is to be hoped that this can be ac- complished. At present, however, reliable information in regard to the yield of logs and trees is possessed by a comparatively limited number of individuals. These persons, by long and in- timate contact with lumbering operations, both in the woods and the mill, have acquired a more or less accurate knowledge of the yield of certain types of timber when utilized by methods with which they are familiar. Unfortunately this type of in- formation is intangible, and non-accumulative since it is buried with those who possess it. Thus the owner or purchaser of timber is dependent upon the judgment and, what has proved in practice to be even more important, the honesty of one or more individuals. Local volume tables carefully standardized to natural and economic factors would serve not only as guides in given regions, but would furnish data for comparative study, the determination of the effect of variation in form, defect, and method of utilization, and the construction of reliable converting factors. As has been stated above, if local tables are to be used in estimating hardwoods, rapid, inexpensive and reasonably ac- curate methods of compiling, tabulating, and standardizing data must be developed. A common practice in collecting material for volume tables is to number the logs in each tree as they are measured in the woods, and subsequently record their contents as they pass through the mill. In the experience of the writers this procedure has been slow and expensive, due to the fact that in most medium sized and large mills a considerable period of time elapses usually between the felling of the trees and their arrival at the mill. Moreover, if the officials of lumber companies or the woods foremen are secretly hostile to the con- 8 Forestry Quarterly. struction of the tables, as several consulting foresters have found to be the case, an effective means of frustrating the work is to delay sending numbered logs to the mill. This difficulty can be avoided if the contents of trees measured in the woods are com- puted from a log scale or 'tally' made at the mill. Errors in- herent in this procedure are in most cases not excessive, par- ticularly if butt logs are separated into a class by themselves. Variations in 'defect' and method of logging, milling, and utiliza- tion have so much weight in the case of hardwoods that the usual fluctuation in the taper of the upper logs of a tree are for prac- tical purposes negligible. In other words the process of follow- ing numbered logs from the woods to the mill is a refinement that is not justified by the accuracy of other phases of the work and of the final application of the tables. A second procedure which deserves attention is the elimination from volume table data of all defective and poorly shaped trees. Graves in his 'Forest Mensuration' states, 'Care is required in the selection of the trees for measurement. It is the rule to measure only sound trees, because volume tables show the full contents of sound trees. It might appear that the tables would be more practical if based on average trees, including those partially defective. But a table made up in this waj' would be extremely unre- liable, for it is well known that the defects of trees differ greatly in different situations ; so that a table based partly on defective trees would be useless in eliminating trees whose defects are different from those of the trees observed in the construction. Again, any such defect as in- jury by fire, insects, disease, wind, or ice would entirely vitiate a table constructed for trees showing another defect than the particular one in question. Whereas a table based on sound trees may be reduced for un- soundness in logs.' In most portions of the Northeastern United States a large percentage of the hardwood trees are defective or deformed. To sort out and measure only sound, straight logs and trees is laborious and expensive. Furthermore, if tables are based upon selected trees they must be discounted whenever they are used even if tlie limber and methods of utilization resemble closely those where the tables' were compiled. In addition the construction and use of tables based upon sound trees presupposes an ac- curate knowledge of the exact effect which different types of abnormalities have upon volume and grade. Unfortunately these converting factors are not available at present, and are difficult to analyze because the influence of a given abnormality is not a constant quantity, but fluctuates widely with variations in meth- Graded Volume Tables. 9 ods of utilization. Since an intensive study must be made of natural and economic factors before applying volume tables in a given region, and much depends inevitably upon the judgment of the estimator, it would appear to be nearly as reliable to apply a "blanket" discount to a table of average trees as to one based entirely upon sound specimens. 'A third source of unnecessary expense, in the construction of volume tables, may result from the super-polishing of tables dur- ing the process of tabulation. Recurving and replotting pro- duce uniform results which are superficially attractive, but tend to show a greater degree of accuracy than is justifiable. Fur- thermore, in wiping out irregularities there is always the danger of concealing the effects of natural and economic factors which should be evident in a table standardized to given conditions. Volume tables are not intended for the determination of the ex- act contents of individual trees. When applied to many trees irregularities due to a limited amount of basic data produce er- rors that are largely compensating. The writers realize that the tables given below are open to numerous criticisms. In the first place more attention should have been given to the study of local methods of utilization and their effect upon grades and volume. In all probability the com- putation of grades for trees of each diameter was not justifiable. However, in as much as these tables are purely experimental it seemed wiser to record the grades than to express them in per centages for groups of trees of different diameters. In using the tables, the cruiser may combine the trees into such groups as he thinks most useful, and quickly determine the percentages of the grades for each group. It should be kept in mind that the data for these tables were secured incidentally, in the course of other investigations. Descriptiox of Local Conditions. I. Topography and Types. Topographically the region is composed of hills and ridges lying between the spurs or branches of the southern extension of the Green Mountains. These hills and ridges are interspersed with numerous level and swampy tracts of considerable size. As a result there is a great diversity of types. The steep upper lo Forestry Quarterly. slopes of the higher mountains which are rocky and have Httle soil, are covered with spruce. It is on the middle and lower slopes of these mountains, and on the lower hills and ridges between them, that the hardwood is found. Here the soil is good and fairly deep, and the hardwood occurs sometimes in a pure stand and sometimes with a varying mixture of fir and spruce. The bottom lands' are covered largely by a spruce type with scatter- ing hardwoods, and the swamps by a typical one of spruce and fir. In many places the hardwood slopes have been cleared and used for agricultural purposes. The farms, however are, now largely abandoned, and the pastures and fields are "coming up" either with a hardwood growth, or a growth of pasture, spruce and fir. The country has been largely cut over for spruce, and there is now little old growth spnice in the region. Conse- quently varying degrees of density occur in the hardwood stands, ranging from those which are always pure hardwood to those in which there are a few scattering hardwood trees left after the removal of spruce. 2. Tree Ponn. The hardwood trees in this region are for the most part two log trees. The merchantable length seldom exceeds' 32 feet at which height the trees begin to branch. In the smaller dia- meters there are of course a number of trees from which only one log is cut, and in the larger diameters a number of three log trees occur. The following is the percentage of one, two and three log trees as obtained in collecting data for the volume tables. Birch: 23% one-log, 62% two-log, 15% three-log; Maple: 22% one-log, 60% two-log, and 18% three-log; Beech: 37% one-log, 58% two-log, 5% three-log trees. In connection with these facts it should be borne in mind that a tree having a merchantable length of 32 feet might be cut either into two 16 foot logs or into two 10- foot logs and a 12-foot log. 5. Defects. Nearly one-half of the logs cut were defective or abnormal in some particular. These logs have been classified according to their defects and their classification is given in an accompany- ing table. In addition to showing the number of logs possessing the various defects', this table also shows the way in which these Graded Volume Tables. II defects offset the volume of lumber sawn from the logs. This is done by dividing the logs into four groups. In group I. are put those in which the defect has decreased the volume of the log io% or less from the volume of a straight and sound log of the same dimensions. Group II contains' those logs in which the defect has caused a decrease of 10-20%, group III a decrease of 20-30%. and group IV a decrease of 30% or more. Under the head of "butt defects" are included butt logs in which butt rot, "dote," or some form of decay is present at the butt of the log. In addition to lowering the total board foot contents of the log these defects may, in cases, also lower the grade of what is' actually sawn. In large logs where there are only four or five inches of butt rot, which does not extend more than a few feet from the butt, the effect is slight upon the volume of the log. "Top defects" include all defects due to rot in the top logs, and also defects in the top of butt logs. Top defects are com- monly more serious than butt defects. This is due largely to the fact that butt defects occur, in the majority of cases, near the center of the cross section, and, in addition, to the fact that there is a greater percentage of shorter lengths among top logs, which makes the trimming of bad ends difficult. Under the head of 'crook' are included longs in which there is a sharp bend or twist. Most of the crooked logs are of smaller diameters, and when a crook is present in a large log it does not have a serious effect unless the abnormality is a severe one. Crook influences volume, but has little effect upon grade. Un- der 'sweep' are included curved logs or logs with a gradual bend. As in the case of crook, sweep is confined largely to logs of small diameter. When it occurs in large logs it is not serious unless the defect is pronounced. Under such circum- stances it will affect grade as well as total volume. This is due to the necessity for cutting across the heartwood. 'Knotty' logs which have abnormally large or numerous knots and are al- most exclusively composed of top logs of the smaller diameters. As a rule grade is affected more than volume. 'Seams' affect both volume and grade, due largely to the penetration of rot along these cavities. 'Shake' is rarely found in beech and maple, being confined almost entirely to birch logs of the largest dia- meters. In addition to affecting volume it has a most decided effect upon grade, in some cases almost the entire volume of 12 I-\)rcstry Ouarterly. a shaky log being No. 3 Common. Miscellaneous defects in- clude such defects as fire-scars, "burls," forks, logs split in felling, etc. When a log had more than one defect it was placed in that class of defect which was considered to be the most serious. The accompanying table gives an idea of the prevalence of each de- fect and its influence on volume. This table includes only such defects as were apparent in the log and does not include defects which were disclosed by sawing. In birch and maple there were few hidden defects, but the beech "opened up" poorer than ex- ternal appearances would lead one to expect. 4. Woods Practice. It was' the practice in the woods to utilize the trees up to their first branches or in the case of the smaller trees to a diameter of eight inches. In other words, the smallest logs sent to the mill were supposed to be 8 inches, top diameter. Practically no logs were taken above the first branches. This practice causes a large amount of material suitable for cooperage stock to be left in the woods, in the form of short lengths. Logs were cut into 10, 12, 14 and 16 foot lengths, and as a rule were saweid to good advantage. The usual stump height at which trees were cut was about 20 inches for trees' under 15 inches D. B. H., and 28 inches for trees over 15 inches D. B. H. 5. Mill Practice. In the manufacture of the logs at the mill a single action band-saw cutting a i" saw-kerf was used. The lumber was graded before seasoning. This was done according to the grad- ing rules of the National Hardwood Lumber Association. Clear boards' not wide enough to go into firsts and seconds were as far as possible graded as clear strips. There was also a con- siderable amount of No. i Common strips. In order to avoid a further complexity of grades, both these grades of strips were included in the No. i Common grade. A small amount of No. 2 Common strips was placed in the No. 2 Common grade. By far the greater part of the output of the mill was sawed into one inch stock, sawed i^" to allow for shrinkage — 85% of the birch, 90% of the maple, and 70% of the beech went into this size. While tlie data were being collected a considerable amount Graded I'ohimc Tables. 13 of dimension stock was sawed for construction purposes about the mill and yard. It amounted to about 20% of the total cut of beech, and less than 5% of the birch and maple. All this dimension stock was graded as No. 3 Common "Stickers," which were taken as much as possible from beech, and to some extent from the poorest maple and birch, were also graded as Xo. 3 Common. At one time, during the collecting of the data, there was a special order for 3 inch stock, 12 feet long, which was graded as Xo. 3 Common, but in reality w^as an intermediate grade between No. 2 and Xo. 3 Common. This tended to in- crease the amount of Xo. 3 at the expense of Xo. 2 in the 12 foot class, and its effect is plainly seen in the birch log rule. In the case of the two highest grades in birch, namely firsts and seconds, and firsts and seconds red, considerable two inch stock was sawed, more especially in the red grade. However, the amount in comparison to the total was small, less than 5%. In the ma])le and beech there were sawed from time to time small lots of i\", if" and 2|" stock but the combined amount of all these thicknesses was less than 5% of the total. In all cases the board.-- were sawed i" thicker than the standard dimension to allow for shrinkage. The beech as a whole was of poor quality, but the amount of Xo. 3 Common was undoubtedly increased considerably by the large amount of dimension stock and stickers sawed from this species. It will be noted that in the ten foot class in the birch log rule, there is a greater proportion of the poorer grades than in the longer lengths. This is particularly no- ticeable in the Xo. i Common Red and in the No. 2 Common grades. It is probably due in part to the fact that the longer logs can be trimmed more advantageously and a limited percent- age of short lengths is allowed in the upper grades ; but largely to the fact that the greater proportion of the 10 foot logs were top logs and hence knotty and of poorer quality. The mill crew, e. g. sawyer, edgeman and trimmer man, were men of average skill, all having had previous experience in hardwood mills of other regions. Methods Used. The following statistics were obtained in the woods : D. B. H. stump height, diameter inside and outside bark at stump and at small end of each log, length of each log, total height of tree, 14 Forestry Quarterly. ■~ %oF — oe „ ^ f^(X) CO oj %oe — 01 QQ -^ Q, o t^ in p9onpa-^ 3iunio/[ ^ -' SSaj pUV O^OJ vooo ar-iChOO p3mpd}i amnio /[ " ^ <^ «>• ^ J xn o w p o tt p0jnp3}j siunio/[ o^oS—o^ p3onp3^ 3mn{0/i o/,oe — 01 p33np3^ 3tunio/i ^S3^ pUV 0^01 p33np3^ dUiniOji TtOO t^ fO -^ "^ • ^ ►H w 04 ►-< »-i 0\ O^O r^ 01 •* p33np3^ 3mnio/[ •Z o/,oS—oe •fe p33np3^ 3iunio/i O O <>< ►-'^ '^^ "^ Oj^Oe 01 t^ „ in IT) rtvo CO vo p33np3^ 3mnioA ^ '^ ^ •* " rs-^7 pwo o/ioi ^vp H Tf t^ o tN.

XYLOMETER CORDWOOD TEST. By R. W. Taylor, Forest Assistant. The test was carried on in the wooclyard of the Crown Colum- bia Paper Company at Floriston, California, the immediate ob- ject of which was to ascertain as accurately as possible the ex- act cubic contents of an average cord of Red Fir cordwood such as is used in making paper pulp. The ultimate object was to ap- ply the factor thus obtained to a Red Fir content volume table so that estimates made in reconnaissance work in the Red Fir region could be readily and accurately converted into cord meas- ure. The Xylometer used was a galvanized iron tank 2.465 ft. in diameter and approximately 4I ft. high, graduated on the inside in i/ioo of a foot. Each stick of cordwood was immersed separately and its volume recorded. The cords were piled after the sticks had been immersed, making each one as far as it is possible to do so, of the standard dimension 4'x4'x8'. The wood measured was a mixture of red and white fir cut from the Crown Columbia Paper Company's holdings near Flori- ston, California, averaging 35% Red Fir (Abies nwgnifica) and 67% White Fir (Abies concolor). As far as can be ascertained, both by inspection and measurements, there is no difference in the form of the red and white fir cordwood. This is borne out by the figures in the table, which show that the cubic con- tents of the various cords bear no relation to the percentage of the two species. jNIoreover, the average number of sticks per cord of the 25 cords is 60. A stack of cordwood containing 10.87 cords and 91% red fir and 9% White Fir measured in another part of the yard averaged 58 sticks to the cord. Thus it will be seen that the size and form of the sticks of the two species are practically the same. The accompanying tables show the result of the test and the resultant factor applied to the volume table. Graded Vulitmc Tables. 25 DETAILS OF XYLOMETER TEST OF 25 CORDS. Percenfasc to.

By N. R. ]\TcNAur,HTON. The fact has long been recognized that the old log rules, de- signed for use with virgin timber of large size, give results which are far from accurate when applied to our present stands of second growth timber. The reasons for this inaccuracy may be roughly outlined as follows : (i) As' stated above, the rules were designed for use with old trees, hence a greater proportionate reduction was neces- sarily made for defects, such as shakes, rot, etc. (2) Logging and milling operations were conducted on a less intensive scale than at present. Measurements* were less accurate, and the waste in the woods and at the mill was greater than it is to-day. (3) Most of the rules are based on incorrect and inflexible formulas or diagrams. By the statement that the formulas and diagrams are inflexible it is meant that they cannot be modified easily so as to be made applicable to local metliods of manufac- ture and local species and grades of logs. It has been the custom of the Pennsylvania Department of Forestry to base its sales on actual mill cut, or on scale by the Doyle Rule plus twenty-five per cent. This latter is a tacit recognition of the painful inaccuracy of this rule in present day use, and the same words apply in greater or less degree to al- most every other log rule commonly employed. To determine just how far the old rules fall short of actual mill cut under average conditions, the Pennsylvania Department of Forestry authorized the collection of data, a part of which the following tabulations summarize. This data was collected in Cameron county, Pennsylvania, during 1912. The logs came from a stand of second growth white pine about seventy-five per cent, pure, which was killed by fire in the spring of 191 1, and was cut the following winter. Only normal, sound, white pine logs were taken; that is, an attempt was made to secure 28 Forestry Quarterly. a fair average lot of logs, but no log was taken for which a scaler would not allow full scale. About eighty per cent, of the logs were sawed into inch boards, and the remainder into two inch plank. All lumber was square edged. The mill was portable, with a capacity of about 10,000 Feet B. M. daily. The saw was circular, and cut one-fourth inch kerf. Edging and cutting to lengths were done as economically as possibly, and there was little unnecessary waste in slabbing. The minimum sizes were eight feet in length and four inches in width. Even lengths and widths only were cut. Table i gives the averages of the mill cut for logs of each inch diameter class in the different log lengths. Table 2 gives corrected values for Table i, obtained from curves. Table No. i.

The above tables show conclusively that the degree of inac- curacy of the old rules varies with the size of the logs; hence the addition of any certain percentage to the scale of a lot of logs by either of the old rules will be unjust one way or the other unless the average diameter of the logs happens to be just what it should be to make the percentage hold good. Thus, the Pennsylvania Department's method of adding twenty- five per cent, to the scale of logs by the Doyle Rule is fairly accurate when the logs average in the neighborhood of thirteen inches in diameter inside the bark at the small end ; but the ap- plication of this method to logs averaging over thirteen inches in diameter is unfair to the buyer, while its application to logs under thirteen inches is decidedly unfair to the seller under these milling conditions. (See Table 3). From this it can be seen that it is almost impossible to so modify the old rules as to make them fit present conditions. The Scribner Rule, it is true, does not make such a poor show- ing as some of the other age-moulded rules, but it leaves much to be desired. The Doyle Rule is altogether indefensible from any point of view, yet it is used more frequently (in Pennsyl- vania, at least) than any other rule. The remedy seems to lie not in the construction of a new rule — of these there is already a superabundance — but in a change of sales methods so that all sales may be based on cubic volume. Each purchaser could then determine his own converting factor * subject to local grades and methods. The present slipshod arrangement of trying to modify the old rules is only putting off until to-morrow what should be done to-day, and what must be done eventually. *The converting factor from used volume in Cubic feet inside bark to board feet mill cut is 5.3 and the outside bark factor is 4.7 for this mill in this lot of logs. LOSS DUE TO EXPOSURE IN THE TRANSPLANTING OF WHITE PINE SEEDLINGS. By E. A. ZlEGLER. The very careful handling of coniferous planting stock be- tween nursery and final planting site is one of the "A. B. C's" in the training of every forestry student beginning work in sil- viculture and its importance may be easily proven. The very obviousness of the need seems' to have kept it out of the field of American forest experiment. However, now and then one may find an over-zealous forester actually giving his plants un- necessary protection and thereby increasing their cost. When one remembers that an extra twenty cents a thousand added to the cost of the plants will in 80 years at 5% add $11.90 to the acre cost of the crop (planting 1200 per acre) — or more than sufficient to establish a new stand by planting a little experi- mental data may have some value in this direction. With a motive arising from several sources this subject for ex- periment was suggested for thesis work to students of the Penn- sylvania State Forest Academy. First, there was held in mind the training for the student in simple original experiment and the proper recording and analysis of experimental results; sec- ond, the emphasizing of the greater susceptibility of coniferous stock to serious injury by exposure to drying out : and third, the extent to which protective measures should be carried without adding unnecessarily to the cost of the stock. The experiment was carried on by Mr. Robert R. Neefe and Mr. Horace F. Critchley of the Class of 1913, and the results are taken from their notes. The material selected was average quality two-year white pine seedlings, since the Pennsylvania Department of Forestry is planting two-year stock principally. The experiment was carried out in the seven-acre Academy nursery in the spring of 1913. The plan required each man to run an independent series of exposures of one thousand plants. First, 100 plants were set out with the exposure reduced to zero as near as possible as a check ; then nine lots of 100 each were fully exposed to sun and 32 forestry Quarterly. wind (lying on the ground) for periods ranging from ten min- utes to six hours and planted. The period of exposure was stopped on the minute and the trees puddled for immediate plant- ing with the planting board. The spacing was 4x4 inches and the transplanted material received no subsequent cultivation or watering although the weeds were kept out. The experiment was carried out on April 4 and 5. The days were bright and sunny: wind moderate S. W. (the nursery is surrounded on west, south, and east by a fairly close stand of 60 ft. pitch pine) : the temperature was about 72°F. : barometric reading 29.2 in.: wet bulb thermometer 63° F. and dry bulb 71° F. (or relative humidty 60%) at time of observation. After planting the wea- ther remained clear for 5 days with the first rain on the 6th day ; except for 15 days of very dry weather April 29th to May 14th. The summer was rather wet and favorable to transplants. The following are the results: Series i Series 2 (Mr. Critchlev) (Mr. Neefe) ^•^ •*»» s S ^ S 1 11^ Q S";; a ^ "^ °o j; 2 <^i =: 2 "^ .«^ K «-) .~ Bxp >osure 2 (Iji PA ?s ■^ -^ S '■ No. Length Time of Day ^ ^s^ ?^ 5-^ f~. ^H i~. nmnber nutnber nuviber I none (check 100 89 83 ,2 10 min. 2.45-55 P.

Other experiments to examine into the weakening effect of heeling in seedlings over winter; the effect of exposure on dif- ferent species and different aged stock ; the relative results on clear and cloudy days, etc., are pending. It is difficult to isolate the factors which it is desired to study but results of some value may be obtained. Certainly the experiments have value in stu- dent training which may be realized in every forest-school nur- sery, even though the results of the experiments do not lead us far beyond our present understanding of silviculture. EFFECTIVE FERTILIZERS IN NURSERIHS. By George A. Retan, * In the spring of 191 1, on the occasion of the sudden illness and subsequent death of the Forester in charge, the writer was unexpectedly placed in charge of the Greenwood Nursery. This nursery is located near McAlevy's fort, Huntingdon County, Pa., at an elevation of about 1200 feet above sea level. The aspect is N. W. and the slope is 5-10°. The soil is formed by the dis- integration of a soft rock of the Clinton group. It is very thin, the rock outcropping in the center of the nursery. The subtype of the surrounding forest is characterized by white pine as the permanent species. The nursery is trapezoidal in form embrac- ing about two acres. At the time of arrival the raising and shipping of seedlings were going on concurrently with 191 1 bed preparation. The two year old seedlings were being removed from nearly two-thirds of the nursery area. It was noticeable that the seedlings from the lower third of the nursery were inferior in vigor, size and color. A scheme was recommended and approved for the improvement of the soil conditions. The nursery was divided into three parts, one-third remaining in beds made the year before and containing a rather poor stand of seedlings. The second third was pre- pared and sown, this being that part of the nursery which appeared to show least evidence of soil deterioration. The lower third, mentioned above, was put under cultivation as detailed be- low. This rotation was continued, and at the end of this, the third season, some results of the treatment can be obsei'ved. The cultivated third was treated as follows. After plowing" early in June, there were applied : 200 lbs. Acid Phosphate, 100 lbs. Sodiiun Nitrate; 100 lbs. Potash (KHO3) ; icx> lbs. Bone Meal. Cow peas and (3ats were then sown and were plowed under early in September when ripening, thus giving a second crop, which was plowed under in November. In the spring of 1912 ♦Instructor in Silviailture, Pennsj'lvania State Forest Acaidemy, Mont Alto, Pa. Effective Fertilisers in Nurseries. 35 the fertilizer application was repeated and the beds prepared. These were made twenty-live by four feet, and each received one pound of white pine seed sown broadcast. On some of the beds, however, red pine and Norway spruce were sown. It should be stated that the white pine seed was not of the best quality, but an amount somewhat under the prescription of Pettis was used because too dense a stand is not desired where the seed- lings are to remain two years in the seedling bed and then be planted out. .About 40% of the white pine seed germinated. The red pine germination was exceptional, too good for the pro- duction of the best seedlings. These are the practical results. In 191 1, 816,000 seedlings were taken from two-thirds of the nursery area. This was by far the largest shipment ever made from the nursery, the aver- age being between three and four hundred thousand. The yield from the third treated as above will be about 500.000 white pine and 200,000 other species, mostly red pine, or a yield nearly as largs as that previously secured on an area twice the size. The one year old beds of the present season will have about the same yield if they come through the winter in good shape. But most significant is the condition of the seedlings'. They are of an intense green color, stocky, well needled, and with good root and bud development. The contrast with the seedlings of three seasons back is striking. The one year old seedlings are also well above the average. This season, 1913, extensive fertilizer experiments were carried on in both the Mont Alto and Greenwood Nurseries under the direction of the Department of Forestry. Forty-nine different combinations were used on as many beds, twenty-five by four feet, in each nursery. The results at the end of the first season are not conclusive as regards some of the combinations, but sorre of the beds have been very instructive. Acid Phosphate is the only fertilizer unquestionably beneficial at this time. Sodium Nitrate as a top dressing has been an absolute failure in every bed tried, causing considerable loss. The minimum amount used was five pounds to 100 square feet, giving .75 pound ^^ actual N. Another experiment of value was carried out by Forester T. O. Bietsch in the Mont Alto Nursery. On heavy clay soil, where uniform failure had met the attempt to rai.se conifers, charcoal 36 forestry Quarterly. residue from old pits scattered through the forest was applied \try heavily so as to form from one-third to one-half the bed. These beds were sown with white pine broadcast and have stood two years. This summer they were pronounced by both Dr. Roth of Michigan and Mr. Dana of the Forest Service, excep- tional in every respect. They supported seedlings fully as large as average three year olds. There is some question as to whether the charcoal acts purely in a physical manner or whether there may be present a considerable wood ash content. This season experiments in testing pure charcoal from the old furnace pile will be carried on. These three years of experimental work have emphasized the superior value of the physical fertilizer for these nurseries. It is believed that the chemical fertilizer can best be applied in con- nection with the green crop, that it will do more good in this way than it will applied directly to the bed. It has been seen that barnyard manure, if well rotted, has been of equal value to any of the above. It is hoped that these results ma}'- be of value to others working under similar site conditions. THE RELATION OF THE SURFACE COVER AND GROUND LITTER IN A FOREST TO EROSION. (As illustrated in a Bavarian Forest). By Maximii^ian J. Gusissnkr, D. Ing Toward the latter part of Alay, 1912, I visited in company with others, some of the forests of the Bavarian administrative district "Pfalz" i.e. the Palatinate. This is one of the eight Bavarian administrative (Hstricts, with headquarters at Speyer. About 599,370 acres, approximately 40% of the area, are forested. Of this 300,700 acres, roughly 50%, belong to the State, nearly 13% is in private hands and the rest consists of communal in- stitutional and association forests. It was our pleasure to have both "Regierungs — und Forstrat" Neblich of Speyer, one of the assistant district foresters and "Forstmeister" Aull, the forest supervisor of Neustadt — Siid to accompany us through the communal forests of the town of St. Martin. St. Martin lies in a valley surrounded by steep mountain slopes with grades ranging from 18 to 22%. The forest cover here con- sists largely of dwarfed pine stands (P. silvestris) , upon shallow brown sandstone * soils. In the valley agriculture is practised by the peasantry and as is often the case in regions with poor soils the forest litter is locally of great economic importance, but its utilization,combined with the comparatively poor soils and the low precipitation. f has been the cause of much damage. In Germany a part of the forest litter is annually utilized. It is either sold at auction to the highest bider or given to persons entitled to this sort of free-use. In some sections of the Pala- tinate each acre of the middle-aged and older stands is raked clear of litter every sixth year. In Baden the litter-gatherers are allowed but 3 days in which to collect the forest litter from the stand to which they are assigned and the use of iron rakes * Lower Triassic formation. t 16 to 20 inches per annum. 38 Forestry Quarterly, is forbidden. On the other hand we find no such provisions protecting the forests and forest soils in the Palatinate. The privilege of gathering forest-litter extends throughout the whole year and when the )-ear is passed only the mineral soil is left*. Even though the sandstone soils at St. Martin are not of the poor- est quality, they are too shallow to endure such treatment with- out showing some decline in quality. Nor are the climatic con- ditions such, that would enable the treated stands to recuperate in the six years of non-use. The utilization of the forest-litter has been in progress for a great many years. At one time the forest litter was of more im- portance than the wood and even to-day there is in St. Martin many a peasant who values his forest more for the litter it pro- duces than for its timber. Many of the stands' are somewhat open and the forest floor was denuded of all living and decaying vegetable matter. These nude soils have no power to absorb much water, as almost any ground cover does, nor do they in any way hinder the water from rushing down the steep inclines, but being almost entirely unprotected soon start to erode much the same as if the area had no forest cover upon it. During and after each extra heavy rainfall great damage was done not only by the large amount of water which rushed down the steep inclines surrounding St. Martin but also by the many tons of debris which were carried down with it and deposited upon the fertile fields in the valley, destroying the crops of the peasants and sometimes even blocking up some of the village streets'. It was the duty of the Bavarian forest service to do all in their pov/er to prevent such damage. If the utilization of the forest- litter could be prevented the vegetable surface cover would reap- pear in a few years, and a large amount of the water would be absorbed by the more porous and fertile soil. Yet the public needs and the public sentiment would not allow an abrupt change in the rules and regulations governing the utilization of the forest- * In cases, such as this, it would be advisable to attempt to regulate the gathering of the litter from late Spring until Sept. i. e. until just before the leaves of the broadleaved species mixed in the stands begin to fall, thus insuring some humus for the soil. Mature stands should be pro- tected for 5-10 years before clearing so as to provide a suitable seed-bed. Relation of Surface Cover to Brosion. 39 litter ; moreover, the greater part of the land situated upon the slopes' is either in private hands or belongs to the communal forests of St. Martin. The forest service then proposed digging horizontal transverse trenches to prevent the downward rush of the surface waters. The peasants had little faith in the plans, in fact even opposed them because they believed that it would hinder the raking up of the forest litter. Finally, in 1899-1901, the forest service, in spite of the opposi- tion of the people, dug a series of horizontal transverse ditches, beginning near the top of the steepest slopes of the state and com- munal forests and only extending them part of the way down, as there was but a very limited amount of money available. In 1905, a vehement rain storm raged in the Palatinate and while an enormous amount of debris was deposited upon the fields underlying the other slopes, those at the bases of the steeper inclines with the transverse ditches were almost entirely un- disturbed. The inhabitants of St. Martin now saw that these trenches had saved some of their farming lands and crops from damage and destruction and it was a simple proposition for the forest service to obtain money to continue the work upon the state and com- munal forests. The following year St. Martin raised $1,500.00, the legislature appropriated another $1,500.00 and a neighboring town contributed $250.00 to be used to pay for the construction of more trenches, to be placed at intervals upon the slopes. The combined area of the slopes which surround the St. Martin valley is 1800 acres, but only one-quarter of the area is traversed with ditches. At present 460 acres contain on the average 3400 running feet of trenches per acre. They cross the slopes horizon- tally and are from 6-10 ft. long, 10-12 inches deep and have an upper width of 20, a lower of 10 inches. The excavated soil is piled along the lower edge and at the ends of each trench so as to increase its capacity. They are laid in checker-board fashion and unevenly distributed, so that the greater number of running feet of excavations are concentrated upon the steepest slopes. At the time these ditches were dug the average daily wage per man was $0.75 and the cost per 100 running feet of trenches 40 Forestry Quarterly. was $0.25 ''\ The total expense was $3,250; the cost per acre only $1.80. t Just two clays before my visit to St. Martin, the Palatinate was swept with one of the heaviest rain storms since the year 1905 and although the trenches were filled with water and sand, there was no damage done to the fields or the village itself. During my stay there, men were emptying these ditches and piling the sand on their edges and the lower sides, so that within a few days after the storm the trenches were again in condition to protect the property of the peasants below. Some few of the private owners neglected to construct trenches upon their forest-lands because of the expense and they claimed that the trenches would encumber the gathering of the forest litter. The peasants had offered the same objection but now find that the forest litter has the tendency to collect in the ditches and this in no way encumbers the raking up of the litter, in fact, it facilitates the work. Since the trenches have been constructed, the soil cover has again reappeared and a fair turf and huckleberry growth now covers the soil under the open pine stands of the steep slopes. This living vegetable cover will soon supply vegetable-mold and together they will prevent the rapid downward rush of the sur- face water and in doing so give the humus and the soil time t(? absorb a larger amount of the same. If the litter would not be collected, there would be but little need of trenches after the for- est floor is again fully established. Although I examined the diameter increment of a number of trees by the aid of a Swedish increment borer, with the expecta- tion of finding an increase in the width of the annual rings, no marked difference could be detected, in fact, occasionally there was none at all. Yet I believe that an increase in increment must result from the greater amount of moisture which the ditches make available for the roots, even though the grass and huckle- berry growth may use a large part of it. *An average of 300 running feet per man. per day — undoubtedly a working day of 10-12 hours. t This is the average cost per acre considering the whole area of the slopes. Although only 460 acres are traversed with ditches (average= 3,300 — 3,400 ft. per acre) this is the more correct way to find the average cost per acre as the surface water of the 1800 acres is controlled by these trenches. FOREST TAXATION ACTIVITY IN MASSACHUSETTS. By Herbert J. MiIvES. Chapter 131 of the Resolves of the Massachusetts Legislature passed during the session of 1913 provides for the appointment by the Governor of a commission of five persons, citizens of the commonwealth, two of whom shall be the tax commissioner and the state forester, to be designated the Commission on the Taxa- tion of Wild or Forest Lands. The duties of the commission are to investigate the effect of present laws relating to the tax- ation of wild or forest lands in this Commonwealth, and the laws and systems of taxation of like lands in other states and coun- tries, and to draft an act providing methods of taxation of wild or forest lands which will develop and conserve the forest re- sources of the commonwealth. The commission is to study the present policy of the commonwealth in the matter of the acquisi- tion and management of wild or forest lands and report what further legislation may be necessary. The report which is to be made on or before the first Wednesday in January, 1914, will contain a compilation of statistics and other information obtained by the Commission. The Commission has held public hearings in cities throughout the state, two of which the writer attended in Boston. The hear- ings were fairly well but not largely attended, and some interest- ing opinions were presented. The opinion was general that the land should be taxed under whatever system is practiced. The writer feels that this is right, land value should be truly as- sessed and taxed, and under no circumstances should this value be exempt from taxation. The chairman of the commission made it plain at the outset that no scheme of exemption is entertained, but the purpose is to ease the burden of taxation on wild or forest land until the timber is cut. The opinion that the small woodland owner should be favored over the large lumberman who owns considerable tracts and is operating at a profit was put forth. Discrimination of this kind puts the state in the position of a dispenser of favors and is wrong. Let a sharp line be drawn between truly wild or forest land and land more suitable 42 Forestry Quarterly. for other purposes, and then apply to the wild or forest land a system of taxation which will encourage reforestation and man- agement. An assessor offered the opinion that there should be periodical re-valuation as values change, starting with stump land and in- creasing the valuation as timber grows. He felt that some in- ducement is needed for leaving seed trees, and that if manage- ment be encouraged taxable possibilities will come. A lumberman presented the view that timberland pays for it- self over and over when wisely cut, and that harm is done when the land or stumpage is sold for a lump sum to a portable mill operator; therefore a system of taxation should be applied which will induce owners to use this kind of land or let some one else use it. He feels that the state should be lenient with the owner when he begins to grow something, and thinks that the land should be taxed each year, and in addition there should be a stumpage assessment when the timber is cut. He proposes' that the state take and own abandoned cutover land, putting it un- der the management of the Massachusetts Forestry Association. Another gentleman interested in timberland expressed the opinion that the tax on forest land might be a state tax, or that the state should adopt a general principle in the matter, leaving details of application in local cases to local authorities, providing appeal in case of dissatisfaction to state authority. This gentleman be- lieves that abatement of taxes on wild or forest lands does not induce management. The President of the Associated Boards of Trade of Essex County presented the views of his association which are widely supported by business men and others interested in the matter in his part of the state: Provide a system which will make re- forestation as little burdensome as possible to the landowner. The landowner who wishes to have the system applied to his land shall enter or list his land v\'ith a state commission for plant- ing or management. The commission shall examine the land to determine the advisability of the work, and to endorse it if the commission thinks it wise, in which case the commission shall make regulations to be followed by the owner. The owner, except by permission, shall cut only for personal use. The commission shall designate trees fit to cut, seed trees to be left, and shall make regulations for reseeding, etc. To pre- Taxation Acthnty in Massachusetts. 43 ^ ent the holders of private pleasure grounds from escaping taxa- tion, the distinction between land suitable for growing timber and land suitable for other uses shall be sharply made. In answer to the question, "Would not the present state forestry depart- ment be suitable to do the work," the gentleman said it would be. The State Forester asked, "Isn't it necessary to have some mandatory laws to accomplish the work?" The answer was, "Probably." The writer believes that land value alone should be taxed, and that timber or other forest products which has grown as a re- sult of forest management should be absolutely free from taxation. Timber which has not grown under forest management may well be taxed as a part of the land. This system would give relief and encouragement to management of wild and forest land. Un- der this system no deferring of taxes until the timber is har- vested would be necessary, for the tax on land value is no bur- den since it is simply tlie taking by the community that which it creates. It is believed that the commission will recommend a system of taxation of wild or forest lands by which the land value will be taxed annually, and the crop at maturity. It is to be hoped that any regulation of cutting on lands bene- fited by the new system will be by volume per acre and not by number of trees per acre as has been done in some cases. COST ACCOUNTS FOR RECONNAISSANCE SURVEYS. By a. B. Con NELL. A simple efficient method of cost accounting is necessary in reconnaissance work if a clear and accurate idea of current, as well as final, costs of operation is to be obtained. The system employed should be sufficiently flexible to permit of the read}^ ascertainment of the effects which increase or de- crease in the size of the party have upon the cost per unit of land examined. Only by this means can the most efficient reconnaiss- sance unit be determined. The comparison of cost figures from different operations can only be made after a strict depreciation has been written off the Property Account in each case. That is to say the depreciation upon the outfit should figure and not the purchase price. This is a point which is often overlooked and operations have often been made to bear the total cost of the purchase of heavy equip- ment which other parties have later used without being charged a proper rental. The cash expenditure therefore, in the case of most govern- mental work, which is continued from year to year, has only a minor influence on the cost of the examination per unit acre. As the size of the operation increases the field efficiency of the party becomes more and more the dominating influence upon the cost of the work. The system of accounting which is described below was de- veloped under practical working conditions and proved quite sat- isfactory in meeting all demands made upon it. A single small ledger, 8 in. x 12 in., of 200 pages is sufficient for six months' work. Nine active ledger accounts will provide all the necessary detail wihout proving cumbersome. These should be opened, in accordance with the usual book-keeping practice, in the following order: Head Office Account. Cash Account. Travelling Expense Account. Supply Account. Cost Accounts for Reconnaissance Surveys. 45 Salary Account. Property Account (Purchases). Freight Charges. Express, Bank and Postal Charges. Cost x'Vccount. The entries are made and the accounts posted in the following manner : Head Office Account: — Debit the total amount of money allotted by H. O. for the carrying out of the work. Credit the monthly total of the Cash Account. Thus at any time the cash expenditure to date is ascertainable. Cash Account :— Debit the cash on hand. On the credit side enter each day's expenditure in detail. At the end of the month balance it off and post the various items to the Dr. side of their respective accounts. From this account a statement for H, O. of the month's expenditures may be quickly drawn up. The remaining accounts are posted monthly from the Cash Account. They show, assembled and in detail, the expenditure on each branch, i. e. Salaries, Supplies, etc. Cost Account: — This account is made up at the end of the operation. On the debit side enter the H. O. appropriation. On the credit post the totals of the various accounts. The balance will show the amount due to or by Head Office together with the total expenditure on the work separated into its various branches. The credit side of this Account will, of course, agree with the total of the Credit column of the H. O. Account. The property which is acquired by transfer should be handled by means of a Property Record Account in the 'back of the ledger. Each item should be entered separately together with the value placed upon it. In figuring the depreciation upon those items which are still in commission at the close of the work the rate should be based on the estimated life of the article in question. By this method the value of any part of the equipment will have been completely written off by the time it is discharged. This will apply to pack ponies as well as to canoes, etc. Articles lost and broken should, of course, be written off in total. Finally a Cost Statement is drawn up for the completed oper- ation. The totals of the various accounts are entered, depreci- 46 Forestry Quarterly. ation upon the outfit is charged and the total cost thus obtained is set over against the area examined for the determination of the unit area costs. Sample Cost Statement. Salaries $1,000.00 Supplies 900.00 Travelling Expenses 200,00 Depreciation of Outfit — On Property Transferred $300 On Property Purchased 100 400.00 Freight Charges 20.00 Express Bank and Postal Charges 3.00 Total Cost of Operation $2,523.00 Cost per unit area of land examined. Cost per actual field work day. Cost of maintenance per man per day. FORESTRY IN AMERICA AS REFLECTED IN PROCEEDINGS OF THE SOCIETY OF AMERICAN FORESTERS. By Barrington Moore. The object of the present review is threefold : First, to show the trend of thought and progress of American forestry as reflected in the Proceedings of the Society of Ameri- can Foresters. For this purpose the articles have been arranged under headings, in chronological order under each heading. Second, to make more available for reference the material con- tained in the Proceedings of the Society of American Foresters, from the first number of Volume VII, number 2, inclusive. Third, to give a general view of the field already covered, in order to show the degree of attention devoted to each subject. I — Historical. The Application, and Possibilities of the Federal Forest Re- serve Policy. By Edward T. Allen. Vol. I, No. 2. Mr. Allen's article is most interesting, throwing light on the adminis- tration of the Forest Reserves in the Land Office days. As he says, it was unfortunate that incompetent men, placed on the Reserves by political pull, antagonized the people by bad management. The Disposal of Public Lands. By George W. Woodruff. Vol. I, No. 2. This article has nothing to do with forestry, but is of interest to Ameri- can foresters in that it gives an account of the development, of the policy with regard to public lands, which gave rise to the present National Forests. Much stress is laid on the frauds practiced to secure public land. Objections to the Forest Reserves in Northern California. By Albert F. Potter. Vol. I, No. 2. Ten objections on the part of the people of Northern California are given to the creation of forest reserves. These objections have since dis- appeared; but they serve to show the opposition with which the reserves first met. Sir Dietrich Brandis. By GiflFord Pinchot. Vol. Ill, No. i. This is an enthusiastic appreciation of the forester who introduced the 48 Forestry Quarterly. science into India, by the man who has done so much for forestry in America. It will serve as an inspiration to all American foresters. Relation Between State and Private Forestry in Pennsylvania. By Joseph Trimble Rothrock. Vol. IV, No. i. This deals with the relation of State forestry to the public, rather than with the relation between State and private forestry. It is full of details of the difficulties encountered by the forestry movement in Pennsylvania. II — General. Forestry and Foresters. By Theodore Roosevelt. Vol. I, No. I. This is a general article showing the vital importance of forestry to the United States as a whole. As Mr. Roosevelt says, the keynote of forestry is and always should be the upbuilding and maintenance of prosperous homes. Bibliography of Southern Appalachians. By Helen Stock- bridge. Vol. VI, No. 2. This is a compilation which will be of great value as a reference for those interested in the purchase of land for forest reserves in the White Mountains and Southern Appalachians. Ill — Descriptive. Deforestation in China. By Bailey Willis. Vol. I, No. 3. The treeless condition of Northern China is strikingly shown. The forests of once densely covered mountain ranges have been destroyed to such an extent that the rich are "reduced to sticks one inch in diameter by eight inches long for firewood." The "saving clause," which does not save the forests but modifies the effect of their destruction, is the wonderful skill with which the Chinese terrace and cultivate the bare steep slopes. Why Prairies are Treeless. By Alfred Gaskill. Vol. I, No. 3. Many facts are brought together tending to prove that prairies were caused by fire. These facts, though interesting, are not conclusive ; and the argumentative tone pervading the article reacts upon the reader. Some Philippine Forest Problems. By R. C. Bryant. Vol. II, No. I. This article gives some of the difficulties encountered in introducing forestry into the Philippines, difficulties naturally attendant upon studying tropical forests containing vast numbers of unidentified species whose growth and silvical characteristics cannot be investigated by methods used in temperate regions. Great as are the difficulties which Mr. Bryant brings out, he does not touch upon the greatest obstacle of all, namely, the sys- tem of Caingins, or shifting, cultivation by which large areas of virgin forests are annually destroyed for the sake of two or three years' miser- forestry in America. 49 able cultivation. Native hostility is also a serious drawback. For further information on the Philippine forests, see article by H. N. Whitford in Vol. VI, No. I. Some Forest Problems in Hawaii. By Ralph S. Hosmer. Vol. II, No. I. An account of industrial conditions in the islands. The minor impor- tance of forestry shows rather strikingly ; but eventually tliere will be an opportunity for valuable silvical investigations. The rnain efforts must, just now, be directed toward protecting the forest land, most of which belongs to the government. Some Forest Problems of the Middle West. By Hugh P. Baker. Vol. Ill, No. i. This paper presents some of the problems of small farm forestry and advocates their solution. It is a general article of the propagandist type. Although containing little specific information, yet it undoubtedly served a very useful purpose. Forest Resources and Problems of Canada. By B. E. Fernow. Vol. VII, No. 2. This is an account of forest conditions in Canada. The first part of the paper is devoted to a description of the timber resources of Canada as known at present, and is illustrated by a map of forest regions. There is less timber, it occurs in more inaccessible regions, and is of poorer quality than in the United States. The second part gives an instructive and astonishng account of the Government's policv and methods with regard to the disposal of its timber. State Forestry Problems. By A. F. Hawes, State Forester, Vermont. Vol. VII, No. 2. The bulk of this article is devoted to questions which arise in fire pro- tection, some of which apply to other eastern States. Protection from insects and animals (chiefly hedgehogs) is also discussed. IV — SiLVICS. Results of a Rocky Mountain Forest Fire, Studied Fifty Years After Its Occurrence. By W. J. Gardner. Vol. I, No. 2. This is the first forestry article appearing in the Proceedings discussing actual forestry work on a specific problem ; and it is perhaps significant that it should have been placed at the end of the number. The autJior gives his observations first in a general manner on the region, then on the influence of aspen, and on the restocking of. the burn, followed by a few figures on the reproduction, growth, and tolerance of Engelmann Spruce. Though no particularly important results were obtained, still this is a distinct beginning. 50 forestry Quarterly. Principles Involved in Determining Forest Types By Raphael Zon, Vol. I, No. 3. This is one of the first purely scientific articles appearing in the Pro- ceedings, and one of the best. The author shows the scientific spirit in reaching after fundamental principles. He states very truly that physical factors are the causes of forest types. He makes one omission in that he fails to point out the importance of certain temporary types in forest management. An example of such a temporary type would be Douglas fir on the Pacific Coast ; in this case the forester should not "endeavor to ob- tain in the shortest possible time the original forest type." Aside from this slight and natural omission, the principles laid down are those generally recognized by foresters to-day. Objects and Methods of Establishing Permanent Sample Plots. By W. D. Sterrett. Vol. II, No. i. Brief and instructive details of the objects and methods of establishing permanent sample plots are given. The article is strictly preliminary ; and the objects given are therefore general. Some work has been done, but no results as yet obtained. This work has since been more highly developed at the Coconino (now Fort Valley) Experiment Station near Flagstaff, Arizona. However, the article shows the beginnings of careful experi- mentation. A New Bxplanation of the Tolerance and Intolerance of Trees. By Raphael Zon. Vol. II, No. i. The author begins with a thorough analysis of the factors affecting transpiration. He proves that on dry soils the influence of moisture is greater than that of light. Then follows account of experiments demon- strating that tree roots dry the soil. This is true enough, but does not bring out the comparative influence of light and moisture on tree growth, and tJiis, after all, is the point, and one which it will be extremely difficult to solve considering the complex inter-relation and inter-action of the two factors. His statement that the lack of reproduction under old trees is not due to lack of light but to lack of moisture is too strong; it might be that with the same small amount of moisture but with light, seedlings would grow. Something might be learned by experiments which would give seedlings the same amount of moisture as that found in the places under the trees v.here reproduction fails, but which would also give them full light. It would seem that Zon's first enthusiasm for this discovery carries him as far in the moisture theory as Pfeil was carried in the light theory. For Zon's niaturer judgment see his and Graves' bulletin "Light in Rela- tion to Tree Growth," Forest Service bulletin No. 92. Some Further Considerations Regarding tlie Tolerance mid Intolerance of Shade. By Herbert A. Smith. Vol. Ill, No. i. Mr. Smith speaks a word of caution against being carried too far by Mr. Zon's enthusiasm for the new discoveries of the effect of moisture on tolerance. Si'zncal Notes on Lodgepole Pine. By E. R. Hodson. Vol. Ill, No. I. This paper gives some very interesting and important facts which were hitherto unknown, and draws logical conclusions about the reproduction forestry in America. 51 of lodgepole pine. The discovery that too dense a stocking was injurious and that about 8,000 seedlings per acre constitute an optinnim full stock- ing is well worth knowing. Some of his other facts arc equally useful. Experiment Stations in Connection With the National Forests. By S. T. Dana. Vol. IV, No. i. The author shows the far reaching significance of the new (this was in 1909) plans of establishing experiment stations on the National Forests, and touches upon some of the problems requiring solution. The estab- lishment of these stations is probably the most important step taken by the Forest Service in placing the profession on a firm foundation. The value of the information which these stations will some day secure cannot be over-estimated. A Study of the Reproductive Characteristics of Lodgepolc Pine. By Gordon E. Tower. Vol. IV, No. i. The author gives basic facts concerning the reproduction of lodgepole pine. Reproduction of this species is "not always so readily secured as was at first supposed." He discovered two forms: (i) that occurring on lime soils with cones difficult to open; and (2) that occurring on silica soils with cones opening readily. He also gives data on the effect of heat and of age of the seed on the power of germination. Economic Possibilities of Pinns Sabiana. By Charles H. Shinn. Vol. VI, No. i. This article belongs under Utilization as well as under Silvics. but was placed here because a large part of it is devoted to a description of the silvical characteristics of this tree. Mr. Shinn calls attention to this little known but abundant tree and gives valuable information concerning its characteristics and uses. Efficacy of Goats in Clearing Brush Lands in the Northwest. By Charles S. Jndd. Vol. VI, No. i. This article gives a novel if not always practicable means of clearing brush lands. The use of goats is probably cheaper than clearing by hand and as effective if the object is reforestation. Basket Willow Culture in Germany. By C. D. Mell. Vol V, No. I. This is a specific article giving some interesting facts, but not all the facts. He does not say how long it takes to grow basket willow or how much it costs. Chaparral Areas on the Siskivon National Forest. By H. E. Haefner. Vol. VII, No. i. This article contains interesting information about the brush fields of Southwestern Oregon, and silvical notes on the occurrence of the different typos on the different geological formations. The point tJia' the brush 52 Forestry Quarterly. areas were deforested by fire is well taken. It would be worth while to impress that fact upon the settlers. His information about the natural restocking of the brush areas is too vague. We should like lo know just what effect the brush has upon reproduction, whether it really aids repro- duction bj' preserving soil moisture or is an unmitigated evil ; what effect it has upon the reproduction of the different species, that is, whether or not a stand formerly composed of pine will be changed to one of a more tolerant species which can come up through the brush ; what species first comes in; and the period required for natural restocking under dif- ferent conditions. His recommendation about reforesting the most favor- able sites first is good. Inter-relation Bettveen Brush and Tree Grozcth of the Crater National Forest, Oregon. By Harold D. Foster. Vol, VII, No. 2. The author has brought together a number of interesting observations on the distribution, classification, and causes of brush ; also its relation to reproduction. These observations tend to show that brush is caused by thinning of the stand due to fire. Brush keeps the soil in condition for reproduction but, he says, injures as much as it aids the reproduction. On this point there is room for argument ; in the northern Sierras brush is the forerunner of a second forest. His attempts to find means of eradicating the brush show the impossibility of doing so except by shading. Sitka Spruce of Alaska. By Bruce E. HofTman. Vol. VIT, No. 2. This article contains silvical observations, chiefly on the occurrence, form and reproduction of Sitka spruce; illuminating details of the lum- ber industry in the vicinity of the Tongass National Forest ; and definite recommendations for reconnaissance, timber sales and methods of cuttine. At the end is a volume table based on diameter and average merchantable length. It is the first detailed information of the tree and region pub- lished. The article is an example of the manner in which American foresters grapple with a new problem. V — Ecology. Plant Formations and Forest Types. By F. E. Clements. Vol. IV, No. I. Professor Clements does a marked service to the profession of forestry by applying the principles of ecology to forest types. In so doing he lays the foundation for a thoroughly scientific study of the relation of the forest to its habitat. The result is that he gives a more stable starting point from whence to attack the complex problem of determining forest types. The article is indispensable for a proper understanding of forest types. The Relation of Soil Acidity to Plant Societies. By Arthur W. Sampson. Vol. VII, No. i. This article is of interest not only to ecologists but to foresters. The author has investigated in a scientific manner the effect of soil aciditj' and of alkalinity upon the occurrence of plant societies. His discoveries re- forestry in .Uncrica. 53 fute the theory maintained by certain scientists that the physical texture and moisture of the soil are of more importance than the chemical con- tent. It is interesting to note that his study on the Manti National Forest showed that most of the tree genera found there prefer acid soils. He should, however, have stated the depth at which these tests were made, since forest soils are liable to be acid on the surface, but may be alkaline where the tree roots penetrate. These investigations are an important step in determining the fundamental physical factors which form the basis of forest types and on which Mr. Zon lays so much stress in his article "Principles Involved in Determining Forest Types," in Volume i. No. 3. VI — Silviculture Silviculture Applied to Virgin Forest Conditions. By Alfred Gaskill. Vol. I, No. 2. This article is a plea for getting down to principles in silviculture rather than blindly following European text books. Hence it is advice rather than an exposition or study of a specific silvicultural problem. But the advice is excellent and has since been followed. A Rough System of Management for Reserve Lands in the Western Sierras. By W. B. Greeley. Vol. II, No. i. This is the best article on silviculture which has appeared in the Pro- ceedings to date. It gives in a nutshell the essential features of the region in question and the leading silvical characteristics of the forest. From these the author evolves a thoroughly sound and practical system of silvi- culture. It is the work of a clear trained mind applying its training in a practical way. It marks the beginning of the true American Silvi- culture. The Siknciiltural Results of Marking Timber in National Forests. By Edward E. Carter. Vol. Ill, No. i. The author gives in a very interesting manner the growth of systems of marking in the important forest regions of the west. Earlv mistakes are shown as well as some of the difficulties encountered and imperfec- tions in the methods used at the time the paper was delivered. The author's one oversight is that he emphasizes the value of the information which technical men can give the rangers without bringing out the fact that the technical man must have a thorough acquaintance with the forest before his advice can carry weight or even be worth following. Condition of American Silviculture. By Henry S. Graves. Vol. Ill, No. I. Mr. Graves shows how little actual practice American foresters have had and how little is known about the fundamental American silvical conditions necessary for developing proper silvicultural methods. He emphasizes ihe necessity of having a definite silvicultural aim : not to for- get what is desired and expected of the forest in the future, but at the same time, we must not become disappointed at failures. Finally he em- phasizes one of the most important truths in forestry, the necessity of knowing principles rather than systems. 54 Forestry Quarterly. Some Notes on the Yellozv Pine Forests of Alabama. By R. C. Bryant. Vol. IV, No. i. The figures on the growth of longleaf pine and the facts concerning lumbering clearly show the impossibility of forestry for private owners of longleaf pine land. Thorough silvical studies would apparently be use- less since there is no government land in Alabama on which the findings could be applied, and conditions in Florida are somewhat different. The silvicultural systems suggested are interesting, but would carry more weight if based on more silvical facts. The Selection System. By Hetity S. Graves. Vol. V, No. i. In this article Mr. Graves brings together much useful information about the system of silviculture with which he has had much experience. It is the system he recommended in his Adirondack Working Plan. The last part of the article is particularly interesting, for he refers to the modification of the selection system known as the "group selection sys- tem" and now widely applied on National Forests bearing uneven aged stands. Management of Loblolly and Sh^rtleaf Pines. By W. W. Ashe. Vol. V, No. i. The author combines scientific information and practical application to a marked degree. He gives specific and fairly detailed information of ■considerable importance. The management, though a little crude, is probably as good as conditions will allow. The article loses by poor presentation some of the force which it otherwise would have. Strip Thinnings. By Theodore S. Woolsey, Jr. Vol. VI. No. I. The author gives a method of thinning dense second growth spruce and balsam stands in the northeast. The method is adapted only to certain infrequent conditions and will probably not be widely used. Results of Cuttings on the Minnesota National Forest Under the Morris Act of 1902. By Raphael Zon. Vol. VII, No. i. Mr. Zon's observations indicate very poor silvicultural results from the cuttings under the Morris act. The seed trees left are wholly inadequate, cutting was done in poor seed years, and the areas have grown up with such rank vegetation as to prevent further reproduction, particularly of white pine. His recommendation about clearing off the brush with fire at the time of cutting is of great interest, but should be most thoroughly tried out before being put into practice. Sihicultural Systems of Management for Central Rocky Mountain Forests. By Carlos G. Bates. Vol. VII, No. i. The author gives an interesting sketch of the determining silvical conditions on each of the important Rocky Mountain types as far as these conditions were known at the time of writing. On this basis he builds Forestry in America. 55 up sound logical methods of silviculture, harmonized on the one side with the interests of the forest and on the other with those of lumber- men. Since the article was written lodgepole pine has been found to be far less intolerant than had been commonly supposed. This would make possible the application of the selection system which the author rejects, but would not prevent the use of the group selection system which he advocates. Border Cuitings: A Suggested Department in American Sil- viculture. By A. B. Recknagel. Vol. VII, Xo. 2. A detailed description of an European method of silviculture applicable only in accessible regions where intensive forestry is possible. Although not practicable for America's present day conditions, the method is worth knowing about for future reference. Siizicultural Systems for Western Yellozv Pine. By Earle H. Clapp. Vol. VII, No. 2. This valuable paper brings together all the silvicultural information gathered by tlie Forest Service concerning western yellow pine. It recon- ciles the two opposing methods of handling the tree, the shelterwood method, and the group selection. Mr. Clapp shows that the latter is applicable to all but unfavorable situations on which reproduction requires shelter. Here the shelterwood system is better for securing new repro- duction. The difficulty is that under present logging conditions much of the stand — up to two-thirds of the volume — must be removed at the first cut, thus largely destroying the shelter. Furthermore the area cannot be cut again for from 30 to 50 years, by which time the reproduction will have been shaded out, or will be badly damaged by the removal of the remaining well distributed portion of the stand. Natural versus Artificial Regeneration in the Douglas fir Re- gion of the Pacific Coast. By Thornton T. Munger. Vol. VII, No. 2. The author describes conditions in the Douglas fir region of the Pacific Coast, and gives the pros and cons of both metJiods of regeneration. He seems to be on the defensive throughout, and ends by saying that, except in four exceptional classes which he mentions above, "natural regenera- tion is practicable, reasonably sure of success, and as inexpensive as any method of artificial regeneration." Such opinions will, it is hc^ed, lead to thorough experiments to determine the applicability of both methods before the Service commits itself to either. VII — Forest ATioN. Problems in Nursery Practice. Bv Clifford Robert Pettis. Vol. IV, No. I. This paper forms a very valuable contribution to all work connected with forest nurseries. It gives in a clear manner the essential details of the author's experience in directing the work of the largest scientifically managed forest nursery in the United States. 56 Forestry Quarterly. The Gro-iving of Eucalypts. By Fred G. Plummer. Vol. V, No. I. Here is what a man wants to know before planting Eucalyptus. It is a general article followed by eleven pages of bibliography of Eucalyptus, so will serve as an excellent reference for anyone wishing further infor- mation on these important trees. Experiments in Sandhill Planting. By Carlos G. Bates. Vol. V, No. I. This article shows very distinct progress in forestry thought and prac- tice. It is detailed, specific, and extremely instructive. The author gives a series of very interesting experiments which were made in such a way as to show how each factor acts and why. The effect of plant competition on the moisture supply is particularly interesting. The article is, there- fore, pure forestry of great future value, not only for the sandhills of Nebraska, but for every other region, as suggesting lines of investigation to be followed anywhere. Hardy Catalpa; a Study of Conditions in Kansas Plantations. By A. E. Oman. Vol. VI, No. i. The author gives interesting and instructive details concerning the starting and care of hardy catalpa stands. He treats the subject in a careful and detailed manner, giving the causes of all the facts and recom- mendations he brings out. The article is tJierefore a valuable addition both to the forester's and farmer's knowledge of handling this valuable tree. Eucalyptus Possibilities on the Coronado National Forest. By R. L. Rogers. Vol. VI, No. i. A thorough knowledge of conditions on the Coronado help to make Mr. Rogers' article of interest and value. He shows clearly that, although certain species of Eucalyptus can probably withstand the temperatures, it is doubtful if they could endure the drought unless previously estab- lished by irrigation. His conclusion is the need for thorough experimen- tation. The article is written in a careful scientific spirit, and should be read by all foresters who have under consideration the planting of Eucalyptus in arid regions. Seed Production and How to Study It. By Raphael Zon and C. R. Tillotson. Vol. VI, No. 2. This article is the result of painstaking and scientific effort. In the first place the authors state the four problems involved. The mere state- ment of these problems is a stimulus to forestry research. The history of the study of seed production is given in detail from its beginning to the present time; presented last is Zon's and Tillotson's method of study- ing seed production, which, briefly, consists in determining the per acre production of seed for any given stand. The method is somewhat com- plex and the idea is not concurred in by all foresters (see discussion of this article in Vol. VII, No. i). Nevertheless the article has vigor and originality and marks a distinct step forward in the professional thought of the country. Forestry in America. 57 Seed Production and Hozc to Study It: Discussion.'-' By S. T. Dana, Bristow Adams, and Raphael Zon. Vol. VII, No. i. This paper is wholly differcnl from any of the others, except Mr. Herbert A. Smith's "Some Further Considerations Regarding Tolerance and Intolerance of Shade," in Vol. Ill, No. i, in that it is a discussion of an anicle which lias already appeared in the Proceedings. Mr. Dana takes the position that Mr. Zon's sample-plot method of studying seed production is too complex and expensive; furthermore it is analogous to the use of yield tables in finding the volume of stands, and yield tables, he says, are of but little use in our irregular forests. His alternative would be to estimate the seed crop by single trees instead of by area, using a previously constructed "seed-volume-table," just as a timber esti- mator uses a volume table of board contents. Mr. Bristow Adams has no faith in either method of studying seed production and believes that there are other problems which are more in need of solution. He gives methods of increasing the seed crop of individual trees. Then follows Mr. Zon's reply to Mr. Dana and Mr. Dana's reply to Mr. Zon, at the end apparently neither being converted. The discussion serves to bring out the advantages and disadvantages of each method. Forest Planting in Northern Michigan. By William B. Piper. Vol. VII, No. 2. This paper relates to the planting done by the Forest Service on the Michigan National Forest. The work has been almost wholly experi- mental ; something of value has been learned, but much further experi- mentation will be necessary. VIII — Mensuration. Timber Estimating. By Herman Haupt Chapman. Vol, IV, No. I. Professor Chapman, and one or two other foresters in the country doubtless understand forest maps and timber estimating better than any- one else. The interest and value of this article is therefore obvious. It is a brief outline of some of the more important methods of timber esti- mating and of the principles underlying them. Timber estimating is of course the phase of the profession closest to the old timber cruisers, a work in which foresters, lacking the experience of the timber cruisers, have surpassed these formerly infallible men by the use of scientific methods. A Method of Studying Growth and Yield of Longleaf Pine Applied in Tyler Countv, Texas. By Herman Haupt Chapman. Vol. IV, No. 2. Of all the methods of stud3'ing yield devised by foresters, this is the most original and interesting. There can be no question that tJie method * The original paper of the same name by Raphael Zon and C. R. Til- lotson appeared in Vol. VI, No. 2. 58 Forestry Quarterly. is thoroughly vvoika'ole and productive of excellent results in longleaf and shortleaf pine ; and also that it is equally applicable to western yellow pine. Furthermore there seems to be no reason why the method should not be used with any species which forms even aged groups. It is at present being tried by the Forest Service in the mixed conifer type (west- ern yellow pine, sugar pine, incense cedar, Douglas fir and the white fir) of the western Sierras, and if successful will probably revolutionize the study of yield throughout the entire country. The Standardt::ing of Log Measures. By Edwin Allen Ziegler. Vol. IV, No. 2. This is a sound article showing clearly the variations caused by different log scales and methods of sawing, and advocating the use of the cubic foot. It is a specific article contributirig something to professional knowl- edge and is also partly propagandist. There is no doubt that the author's recommendations will eventually be adopted, but not for a long time or without a struggle. This should not, however, prevent foresters from keeping the end in view and making every effort to attain it. Forest Mapping and Timber Estimating as Developed in Mary- land. By Fred W. Besley. Vol. IV, No. 2. The work herein described is instructive in that it shows how to get a rough but sufficiently accurate idea of forest areas and stands in a woodlot state. It will be of considerable value to those starting forestry for the first time in a state, and to foresters in states which have for some time applied the science. The Log Scale in Theory and Practice. By Harry D. Tieman. Vol. V, No. I. This article is the result of much original research in the important and complex subject of log measurement, in consequence the author is able to give in considerable detail the underlying principles of his subject. He has also evolved, as a result of the actual measurement and sawing out of 224 perfect logs, an ideal rule which he expresses by a formula. The article is a valuable contribution, not only to the scientific knowledge of the profession, but also to the practical application of this knov/ledge to the lumber industry. IX — ^Engineering. A System for Getting Topography in Reconnaissance Work in the Western Cascades. By Walter H. Leve. Vol. VTT, No. 2. The article gives the details of the topographic part of the reconnais- sance in the western Cascades of Washington. The nature of the subject, together with the none too clear style of the author, would make this paper difficult to understand for one without much topographic experience. Since the article will be read chiefly by men engaged in this work it will have value for starting discussion and suggesting improvements. One im- provement would be to have the field man complete his sketch in the field rather than turn in a series of short contours. Forestry in America. 59 X — Management. Some Government Timber Sales in the Southwest from the Practical and Technical Standpoint. By Theodore S. Woolsey, Jr. Vol. II, No. I. This paper gives an account of mistakes made in the earlier adminis- tration of timber sales. These mistakes, however, laid the foimdation for the better administration of to-day. Managing a National forest from the Business Standpoint. By Theodore S. Woolsey, Jr. Vol. Ill, No. i. This paper throws an interesting light on the administration of the National Forests in 190S, and contains valuable suggestions. For example : His point about salaries and corresponding efficiency is well taken ; his suggestions about keeping track of a Forest Officer's work, and about cost keeping have since been put into effect; while his recommendation of a more conservative use of the ''raw product" (timber) has, owing to the necessity for making sales in order to put the Service on a paying basis, not yet been followed. However, with proper silvicultural methods of timber marking, there is no danger of depleting the capital. The New Reconnaissance — Working Pla y. c.

By Charles C. Adams, Ph. D. The Macmillan Company, New York. 1913. Pp. 1-183. Price $1.25. While the book of the above title is concerned entirely with animal ecology, yet its general discussion of the aim, content and point of view of ecological study is so apt and so applicable to forest ecology that it seems worth while to present an abstract. Ecology has no aim, but ecologists have. The problems of an ecologist are not fundamentally different from those of any other kind of naturalist. The superficial differences in aim are due to different points of view or methods of approach, rather than to any essential difference in the character of the problems. The relations which different branches of ecolog}' bear to one another may be discussed under three headings, namely, indi- vidual, aggregate and associational ecolog>^ The study of individual ecology is the investigation of the de- velopment (process of formation) of the structure, function and behavior of a given individual from the standpoint of its re- lations and responses to the complete environment. Such a study may be limited to a single habitat or locality, or extended through- out the entire geographic range of the form. From this stand- point, the individual studied becomes the hub of the microcosm from which all relations and responses radiate. The organism is thus considered as an agent which, transforming and utilizing substance and energy, produces a varied number of physiological conditions and forms of activity, which, in turn, furnish the basis for the constant process of response between the organism and its environment. The study of aggregate ecology is the investigation of the ecological development, relations and responses of animals and plants based upon hereditary or taxonomic units, as in a family community or in genera, families and orders. These groups or aggregates are made the basis for ecological study, as a hive of bees or the genus Pinus. From this approach the activities and responses of the group are traced within the nrea studied or Current Literature. 71 throughout the world. The hereditary or taxonomic unit is here the hub of the microcosm. Here also the aggregate is considered as an agent or entity which produces many kinds of activities and adjustments to the environment. Associational ecology is devoted to the investigation of the development, inter-relations and responses of animals and plants which are grouped or associated in the same habitats and envi- ronments. In this case the associates in a given association and habitat are considered as a unit whose activities and inter-rela- tions and responses are investigated in the same manner as if it were a single animal or plant. The interactions among mem- bers of an association are to be compared to the similar relations existing between the different cells, organs or activities of a single individual. Such groupings have a composition which has developed into an arrangement or "spacing" of individuals within it, and which produces a particular plan or pattern, as a result of the innumerable responsive activities' on the part of individ- uals which live together. For example, when the tiers of vege- tation in a forest are treated as a unit, the entire history of the plants in the habitat is considered as a response to the conditions of life therein. In this form of study the association becomes- the center of all radiating relations and responses. Such an as- sociation is an agent which transforms substance and energy, producing varied physiological conditions and responses in that continuous process of adjustment which constitutes life. In discussing the value of ecological surveys, the author con- cludes that their main advantages are : ( i ) the record of natural environments and their associations for future generations; (2) the study of natural biotic conditions, giving a perspective not derived in any other way; (3) the clearer conception of the dynamic relations of the balance of nature, biotic base and climax associations; (4) emphasis of the process and interpretative phase of scientific investigation over that of purely descriptive study; (5) facilitating the invention of multiple working hy- potheses which bear upon animal and plant responses in nature; (6) furnishing important conceptions to the study of the pro- cesses of adaptation and the struggle for existence; (7) furnish- ing important general principles of great value in applied ecology ; (8) furnishing one of the best methods of learning how to get 72 Forestry Quarterly. acquainted with the living aspect of the animals and plants of any region. Some of the other chapter headings are : The laws of envi- ronmental change ; the laws of internal change ; the continuous process of adjustment. The volume should be in the hands of every investigator or teacher whose subject includes' or impinges upon the field prob- lems of biology. C. D. H. Michigan Bird Life. By Walter Bradford Burrows. Michi- gan Agricultural College. 1912. Pp. 1-802. In the introduction to the technical descriptions of the birds and their habits, the author discusses briefly the bird life in rela- tion to vegetative regions. In the Prairie Region, an extension of the prairie regions of the adjoining States of Indiana and Illinois, one finds in the more open country the prairie chicken, meadow lark, killdeer, mourning dove, marsh hawk, turkey buz- zard, prairie horned lark, lark sparrow and bobolink. Along the tree fringed streams are found the bronze grackle, red- shouldered blackbird, red-headed woodpecker, flicker, and less often the red-bellied woodpecker, orchard oriole, prothonotary warbler and the sycamore warbler. The knolls and ridges here and there harbor the bob-white, the tufted tit. blue gray gnat catcher, and an occasional yellow breasted chat, mocking bfrd and Carolina wren. The White and Red Pine Forest Region is now little more than a name, and it comes more properly under the head of cut- over lands and much of it under burned-over lands. In the southern peninsula it formerly extended northward of a line ex- tending from Van Buren County in the southwestern corner of the State, northeastward to Gratiot County and thence eastward to Port Huron. The pines were always distributed irregularly with areas of hardwoods and swamps, the pure stands being on the sandy uplands drained by the rivers. The characteristic birds of the real pine forest are comparatively few. Among them may be included the pileated, three-toed and hairy wood- peckers, the two species of nut-hatch, the black-capped chickadee, brown creeper, Canada jay, black and white, pine blackurnian and black-throated green warblers. Current Literature. 73 The Jack Pine Plains lie in general within the pine region out- lined above, and they are the more sterile soils farther from the streams. They are characterized by an abundance of Jack Pine, several scrub oaks, aspens, pin cherry and service-berry. The undergrowth is chiefly composed of sweet fern, wintergreen, bracken fern and various blue berries. Areas of this descrip- tion cover about two million acres in the State, and their sum- mer bird life is characterized by the vesper sparrow, chipping sparrow, field sparrow, robin, bluebird, night hawk, kingbird, blown thrasher, catbird, bluejay. red-eyed vireo, indigo bird, sparrow hawk, goldfinch and cowbird. The Hardwood Forest Region in the upper half of the lower peninsula still includes many hundreds of thousands of acres where there is a heavy growth of beech and maple, with which is intermixed birch, basswood, hemlock and scattering White Pine. Among the more characteristic birds of this region in order of abundance are : Hairy and downy woodpeckers, wood pewee, hermit and wood thrushes, solitary vireo, sapsucker, crow, rose-breasted grosbeak, scarlet tanager, oven-bird, broad- winged and cooper's hawk. Burnt-over lands, of which there are millions of acres in the State, VBiVy much in their bird life according to the nature of the original forest, whether largely pine or hardwood, and espe- cially the length of time which has elapsed since burning. One may travel for hours through the more desolate regions and see but few birds, the most common being the vesper sparrow, field sparrow, chewink, nighthawk, kingbird and cowbird. The deep woods, whether swamp or upland, never shelter the wealth of bird life found in partly cleared or well cultivated dis- tricts. Stream borders, lake margins or other openings of the forest always teem with bird and insect life, for here a greater variety of conditions is found and larger numbers of birds seek the sunlight and shade, the food supply and shelter which in- sure, so far as wild nature can, the welfare of their young. The greater part of the volume is concerned with technical descriptions, habits and distribution of the Michigan birds. C. D. H. 74 I'oresiry Quarterly. "A Working Plan for the Woodlands of the New Haven Water Company." By Ralph C. Hawley, Assistant Professor of For- estry, Yale University. Yale Forest School — Bulletin 3. New Haven, Yale University Press, 191 3, 8 Vo., 30 pp., i map. It is refreshing to read a forest working plan which has been working in the forest for some years. The title page explains that the plan is "prepared after five years of forest practice," and the text is full of meat as regards things that have been done, and of helpful suggestions in and between the lines to those of us who are trying to do something with hardwoods and white pine in the northeast. A managed forest area of about 8,000 acres, in the midst of one of the most densely popu- lated regions of the United States, yet in a section about one- half of which is forested; with unusual markets because of a wide variety of manufactures; handicapped by the fact that the holdings are widely scattered in many separated and irregular blocks, and by the further fact that a large part of the area either is in the younger age classes, not yet merchantable, or is open land to be planted — here is a combination which makes the working plan one of real interest to those who are located where intensive forestry is possible. And to others, working where "we might as well forget for the time being most of what we learned in the forest school," it should be an earnest of good things that, with patience, will come to us as American foresters. The bulletin should be placed in the hands of every Water Company and every City Water Board in the country. Lands permanently controlled for the purpose of protecting potable waters offer so exceptional an opportunity for the practice of forestry, even under adverse economic conditions, that in this field should come one of the next substantial developments in forestry. The present low financial returns from the New Ha- ven property, as described in the working plan, may at first thought be discouraging to officials who may become interested. In reality, however, these figures are not discouraging when one considers the fact that the lands were in such unproductive con- dition at the start, and that the property must be held anyway, whether or not forestry is practised. In reading the bulletin with the idea of using it to incite the interest of water companies in forestry, one cannot help but wish that some attempt had been Current Literature. 75 made to predict future financial returns. But on the other hand, one realizes that his satisfaction with the bulletin rests upon the fact that it tells things which have been, and which are sure, rather than things which may — or may not — be. A number of copies of this working plan, sufficient to loan one to each student in the class in forest management for purposes of seminar discussion, would be valuable laboratory material for every forest school. It would serve as the starting point for the useful review and discussion of many topics, such as the purpose and structure of a working plan ; forest descrip- tion ; the relation of various site factors to practical operations in the woods ; forest types ; planting ; thinning ; protection ; yield ; utilization ; stnmpage prices ; financial returns. A few questions might be asked about some things in the bulletin. In classifying the lands, the distinction between graz- ing land and forest land is "based more'on the present condition and probable use for the next few years than on the actual value of each site for producing farm or forest crops" ; has the author been able to arrive at a satisfactory basis for the final separa- tion into grazing land on the one hand, and forest land on the other hand, in cases where be wishes to make the final choice? Would it not be desirable to include a list of the scientific names of the species? ("Whitewood'' may be applied to only one species in Connecticut, but it is applied to other species else- where.) Are the overhead charges included in the expenditures, in Table 7? What is the labor wage, on which the planting costs are based? In view of the deficiency in growing stock, why would it not be well to leave for the present the stands seventy years of age and older (p. 26, bottom), if these stands are still sound, thus restricting the cutting to the two classes of timber mentioned in the previous paragraph as being the only ones to be removed ? * Among the points of interest in the bulletin, the following may be mentioned. "In a few cases cordwood and timber have been sold to reliable pur- chasers on a basis of 60 per cent of the difference between the total ex- penses of manufacture and the total receipts from sales. By this ar- rangement the Companj"- receives 60 per cent of the difference and the purchaser, who finances and attends to the entire operation, 40 per cent. *There is a slight typographical error on the last page, where "plant" should be "plan." 76 forestry Quarterly. The results so far have been fully as good as could have been secured through selling by any other method." Stumpage values are: cordwood, $.30 to $1.50 per cord; No. i ties, $.30 to $.45 ; 30 and 35 foot poles, $1.00 to $2.25 per pole ; hardwood lum- ber, $4.00 to $10.00 per M. bd. ft. ; hemlock $3.00 to $5.00 per M. bd. ft. The annual growth per acre per year is: hardwoods (chestnut and oak), 0.3 to i.o cords; hemlock, .25 to 0.8 cords; white pine, 0.4 to i.o cords. "One (chemical) extinguisher or pump to every fifty acres of planta- tion would be good economy" in protecting from fire. "Except in rare cases the brush and tops will be left as they lie after cutting. It is considered unnecessary to dispose of them as an aid in pro- tection, because the chief hre danger comes from the hardwood leaves spread in a comparatively uniform layer over the ground. A fire will start and spread readily in leaves, and tops only add to the intensity of the fire. Hardwood tops inside of two years partially decay and absorb so much moisture that they burn with difficulty. The brush should be piled and burned on clear cut areas which are to be immediately planted." Most of the planting is with white and red pines. (It is good to see that this tract was not reached by the Scotch pine fad, which for a time, in some sections, seemed likely to rival the catalpa mania in extending these species beyond their legitimate sites.) Poor planting sites are avoided until the best sites are planted — let more of us remember this. Three- year-old, once transplanted stock is ordinarily used. Spacing is 6 x 6 feet. The total cost of the transplants, grown in the company's nursery, "was $3.80 per thousand or $4.60 per acre of plantation." Planting "cost $7.20 per acre, thus making the total cost of the plantation $11.80 per acre." "Fail places in the plantations made the preceding year should be filled each year if the loss exceeds 25 per cent., or in case of a smaller loss if in the form of a few relatively large patches instead of being scattered uniformly. "Certain stands in the old field and hardwood types are suffering from the grazing of cattle. In nearly all of these cases the land is owned by the Company but subject to the life use or use for a period of years by the former owner." (Avoid rights and servitudes whenever possible!). "Stands (of hardwoods) younger than fifty years rarely yield enough merchantable timber to be considered mature. The site must be quality I and the stand contain a large percentage of chestnut to be merchantable before the fiftieth year." The classification of forest types is based exclusively on present con- dition, without regard to what the area is capable of producing. The types are hardwood, hemlock (80 per cent, or more of hemlock, as judged by the crown space occupied), pine (80 per cent, or more of pine), old field, agricultural, administrative, and barren. Old field type automati- cally becomes pine type as soon as it is planted. There is a wide varia- tion in the composition of the hardwood type. All hardwood stands, except gray birch, are grouped together as the hardwood type, regard- less of whether the dominant genus is chestnut, oak or maple. "Boundaries of compartments are usually ridges, streams or public roads and are easily recognizable. Compartment divisions are permanent. A compartment may contain a number of different forest types and age classes. There are in all fifty-one compartments, ranging in size from less than 50 to over 400 acres. Each compartment is divided into as many sub-compartments as it has individual stands, that is, portions of the forest differing in age or type. A single sub-compartment contains only one type and only one age class, and serves as the smallest unit considered. There are few sub-compartments of less than an acre, while the largest contain about a hundred acres. Sub-compartment boundaries are often not marked on the ground, being distinguishable as lines of difference be- tween types and age classes. These boundaries are subject to change Current Literature. yy with each revision of the maps. There are more than 700 sub-compart- ments." The working plan records are kept "on s x 8 inch cards printed with the proper headings. Each carries the description of a single stand or sub- compartment." W. M. Report of the National Forest Reservation Commission. Sen- ate Document No. 307, 63rd Congress, 2d Session. Washington, D. C. Dec. 8, 1913. Pp. 8. This report shows that during the fiscal year ending June 30, 1913, the Commission approved for purchase 425,717 acres, mak- ing a total of 713,415 acres approved up to that date. This area is classified as follows : Acres Virgin timberland, 222,120 Cut-over or culled timberland, 397»390 Lands on which timber is reserved, .... 33,224 Abandoned farm land, 7'^/^ Unmerchantable or barren, 52,803 713415 The lowest price paid per acre during the fiscal year ending June 30, 1913 was $1.09 and the highest $13.25. The average price for the purchases during the year was S4.71 per acre, while the average of all purchases has been $5.07 per acre. The Forest Service examined during the fiscal year 542,202 acres at a cost of 10.6 cents per acre. The Geological Survey has examined 88 per cent, of all the area within the proposed pur- chase areas, so far having made no unfavorable reports. The Commission has adopted the poUcy of purchasing only on an acreage basis', the acreage being determined by a survey by horizontal measurements. The rough character of the coun- try surveyed and the indefiniteness or entire absence of marked liens and corners has made the cost of surveying relatively large, the average during the past year being 20.5 cents, per acre. This will be reduced during later years because it has been neces- sary to sun^ey lines of other tracts which are not now under con- sideration but which may later be offered for sale. 78 Forestry Quarterly. Titles are examined as the surveys are in progress by officials of the Department of Agriculture, who report to the Attorney- General through the U. S. Attorney for the District in which the lands are located. During the past year the Attorney-Gen- eral has approved the title to 15 tracts, comprising 72,183 acres and has declined to approve the title to 12 tracts comprising 106,824 acres. The Secretary of Agriculture has requested that condemnation proceedings be brought to perfect the title of the tracts which were not approved. Where there are no special difficulties in the way of perfect- ing a clear title, the Government has been able to make final purchase from six months to one year after the purchase is approved. Where condemnation proceedings must be brought a further period of from six months to a year is required. The lands already acquired or whose purchase has been ap- proved are now in charge of forest officers who have charge both of administration and of the examination and survey of other lands within their area which are under consideration for pur- chase. Two hundred and fifty miles of trail have been constructed for protection purposes and the construction of a few tele- phone lines has been undertaken where their need is imperative. The Commission recommends that legislation be enacted to increase the allotment of all moneys received from each national forest created under the Act of March i, 191 1 from 5 per cent, to 25 per cent., because the proceeds are insufficient to compen- sate the counties for the loss of taxs on the lands acquired by the Government. R. C. B. Cottomvood in the Mississippi Valley. By A. W. William- son. Bulletin 24, U. S. Department of Agriculture. Dec. 31, 191 3. Pp. 24. This bulletin deals in a comprehensive manner with the econo- mic importance of the cottonwood, botanical characteristics, growth and yields of stands, and management. Under the head of "stumpage values and logging costs," the author offers the following formula, based on operating costs, for the determination of stumpage values, namely Current Literature. 79 M S=- (L4-Mf) I. op in which S equals the stumpage vahie; M equals the sale value of the manufactured product; i.op represents the rate per cent. profit on each thousand board feet ; L equals the logging costs ; and Mf equals the sawmill costs. The principle of profit on operating co.sts, on which the for- mula is based, is not sound economicall}', since profits should be based on the amount of capital invested in the business. The reasons for this are many and cannot be discussed here in detail. The author has' been led astray in handling his stumpage values after they have been determined by the erroneous con- ception of the proper method of determining profit. He says "if several years are required to complete the logging operation, however, this formula should also include the interest on the money invested in stumpage, and the stumpage value in such an event would be found by deducting the interest at a fair bor- rowing rate, say 6 per cent., for the average length of time in- vested." In other words, after finding what an operator can afford to pay for stumpage to-day, he discounts that value if the buyer does not wish to cut the timber until some future time. It is evident that if a purchaser did not choose to utilize his stumpage, say for 20 years, that the seller, according to the above reckoning, might not only have to give his stumpage away but also present the recipient with a good sum of money besides. In actual sales we know that this is untrue and that the man who buys timber to cut 10 or 20 years hence has to pay just as much to the seller as does the man who expects to cut it within a year — since the present value is the same in either case. This erroneous method of handling interest is due to the attempt to calculate profits on the basis of operating costs instead of investment. The buyer should get interest on his investment in stumpage and if he makes a good buy he does so through the increase in the value of his stumpage, if in no other way. During the early years of an operation which carries a heavy investment in plant and stumpage, the amount of money on which interest and profit may be secured often is so great that for the first few years little or no profit can be actually made. As the investment is reduced — the stumpage also gradually ris- ing in value — the returns are sufficiently great to permit a gracki- 8o forestry Quarterly. ally increasing profit, and during the later years of the opera- tion, the profits will be far above normal and will more than compensate for the passing of the dividend during the first years the business was conducted. It is inconceivable, however, that the operator would expect the seller to reduce his stumpage price as the length of time it was to be held increased. In discussing the growth and yield of stands the author states that fully stocked pure stands, 40 years of age, yield an average of 31,000 board feet per acre and that some stands will cut as high as 36,000 board feet on the overflow bottom lands of the Mississippi Valley. Fifty year old stands in Minnesota and Iowa uplands will seldom cut more than 20,000 board feet. The author points out the practicability of growing cotton- wood on a commercial basis in the bottom lands of the Mis- sissippi river. On account of the expense of establishing new stands by planting, it is recommended only where there is an uncertainty of. securing a new crop from seed trees. Natural reproduction is recommended on bottom lands subject to over- flow in the spring but which are only moist when the seed falls. It is not successful on low ridges, or where spring overflow is uncertain, and planting is recommended for such sites. Coppice reproduction is not recommended because many stands will not be cut until they reach 35 or more years, at which age the stumps have lost much of their sprouting vigor. The latter declines rapidly after the tree is 20 to 30 years old. Sprout management is recommended only for stands managed for pulp- wood on a rotation of from 10 to 13 years. At the latter age the largest average annual yield per acre is secured, namely 47 cords. A rotation of 35 years is recommended for saw-log produc- tion in natural stands of pure cottonwood, at which time the maximum mean annual yield is about 840 board feet per acre. This is based on present market requirements. The average returns from growing cottonwood for saw-logs is estimated at from 6 to 7 per cent., and on pulpwood only from 4 to 6 per cent, due to the low value of cottonwood cordwood. In summarizing, the author states that cottonwood is destined to play a large part in the future production of lumber, veneer and pulpwood in the Mississippi Valley. Current Literature. 8l Cottonwood will not renew itself on cut-over land unless spe- cial care is taken in logging. Natural reproduction may be em- ployed to advantage in some places but in others it will be neces- sary to employ artificial reproduction exclusively, and it will be desirable in most cases to supplement natural with artificial re- production to secure a fully stocked stand. R. C. B. Annual Report of the Director of Forestry of the Philippine Is- Imids for the fiscai year ending June 50, jp/5. Manila Bureau of Printing. 1913. Pp. 65. In discussing legislation passed during the fiscal year, men- tion is made of the attempt to revise a portion of the Forest Act, passed in 1905. providing for the method of payment for stumpage cut from Public Lands. The legal forest charges are based on the volume of the round log but if the licensee elects to manifest his timber after it is sawn, he may do so by paying an additional 15 per cent, on the lumber manifested. The latter practice has been adopted by all millmen since the 15 per cent, addition is absurdly inadequate to cover the waste in manufacture. Great encouragement has been given to wasteful practices in slabbing, edging and trimming lumber. The millmen also saves only the best grade boards which he can sell at a good profit and throws away inferior grades with no loss to any one except the Government. The law is so favorable to millmen that eflforts to change it have so far not met with success. A new policy has been adopted in the management of the forests which are now being cut under exclusive licenses. The areas are being classified into agricultural land and forest land and a definite policy of cutting prescribed for each. Fire protection is also being forced on the licensees with good results. The requirements include the use of spark arresters on locomotives and logging engines, and the maintenance of an ade- quate patrol. These are the chief features at present but if licensees do not keep fire from their areas by these means, they will be forced to burn their slash. Authority is to be requested from the next i\ssembly for the appointment of Field Assistants, who will be drawn preferably from the ranger stafif of the U. S. Forest Service. These men, if appointed, will be placed in charge of large timber sales. The appointment of a lumberman will also be requested. 82 Forestry Quarterly. The records show an increase of 17 per cent, in the number of licenses granted for all classes of forest products and the amount of timber cut was 23 per cent, greater than in the pre- vious fiscal year. The greater increase in production was in the lower group woods which are used chiefly for construction purposes in the domestic markets, but which are being used in increasing quantities in the United States for furniture, finishing lumber and cabinet purposes. The total revenue from forest products was $195,331.94 (gold) and the Bureau expenses were $113,524; an increase in revenue of $17,989, and in expenses of $13,104 over the previous year. An interesting feature of the work is the rapid establishment of communal forests, forty-five having been set aside during the year, the total now reaching 148. Among the activities of the Division of Investigation are men- tioned a study of the planted mangrove groves, which are used for the production of firewood ; the nipa swamps ; durability tests of timber; and of reforestation of lands covered with cogon grass. Well established stands of ipilipil (Leucaena glauca) are reported to produce annually 10 cords of firewood per acre. Considerable space is devoted to a report on a forest reconnais- sance of the Island of Bailan containing 120,601 hectares. The estimated stand of timber is 3,585 million board feet. The average stand per acre on the commercial forest areas ranges from 16,000 to 24,000 board feet per acre. The cost of the reconnaissance, which covered a period of five months, was $2,- 258.50 (gold), which is regarded as a very low figure for this kind of work. The report shows substantial progress in all lines of forest work and with the increased efficiency measures constantly b«ing inaugurated in the administrative work, we may reasonably hope for still greater results in the future. R. C. B. Report of the Director of the Bureau of Forestry (Philippines) to the Secretary of the Interior (Phil.) on the Forest School. 1913- This is a manuscript covering the work of the Philippine Bur- Current Literature. 83 eau of Forestry, Forest School, which was submitted to the Phil- ippine Legislation through the Secretary of the Interior. As early as 1903 an agitation was started in the Bureau to establish a school in which Filipinos could be trained for Ranger and other positions but it was not until 1910 that the project be- came possible. In April of that year the Philippine Legislature authorized the Director of Forestry to appoint twenty forest pensionados and to construct temporary buildings for their use. This marked the beginning of the Forest School, which was established in co- operation with the College of Agriculture of the University of the Philippines, at Los Banos, Laguna. The number of forest pensionados authorized has now been increased and the number of scholarships at present is fifty- three. There are at present 58 students in attendance, representing twenty-seven provinces, in addition to two rangers detailed from the Bureau, three Chinese students, two students from the Island of Guam and one private Filipino student. Two courses of study are offered; a two-year course for the pensionados and a four-year course leading to the degree of Bachelor of Science in Forestry which is open to students who are graduates from the Philippine high schools or who have equivalent training. The law provides that "such scholarships shall be awarded to students who have completed at least the second year of the high school course and who shall be appointed by the Director of Forestry upon recommendation of the Director of Education. The scholarships entitle the holder to reimbursement of his traveling expenses from his home to Los Banos: to free living quarters, free tuition, and to a monthly cash allowance of $12.50 gold. From this it can be seen that the Government is very lib- eral in its attitude towards the student who is fortunate enough to secure a scholarship. The curriculum of the two-year course covers the following subjects : Junior Year Botany Physiography Mathematics Silviculture Forest Engineering- T Forest Engineering II : Dendrolosfv summer vacation 84 forestry Quarterly. Senior Year Wood technology Silviculture History, law, and procedure Forest AJanagement Forest Engineering III The four-)ear course is more comprehensive and includes among other things chemistr}% physics, advanced silviculture and the preparation of a thesis on some forest subject. The faculty consists of employees of the Bureau who are assigned to the Forest School staff temporarily. The chief field for graduates of this school is in the govern- ment forest service, which has already absorbed the two classes, comprising forty-two men, which have left the institution. These men, on appointment, receive a salary of $25 to $30 (gold.) The marked improvement noted in the efficiency of the native force since the school has been established, is sufficient proof of its great value and it is to be hoped that the institution may be continued and placed on a sound financial basis in the near future. It is neither practicable nor desirable that the majority of tlie Bureau staff should be composed of Americans and it is' believed that the way has now been paved for the upbuilding of an ef- fective native force which will handle the valuable forest re- sources of the Islands in a wise and conservative manner. R. C. B. Western Grazing Grounds and Forest Ranges. By ^Vill C. Barnes, Inspector of Grazing, U. S. Forest Service. Pp. 390. The Breeders' Gazette, Publisher. Chicago, Illinois. 1913- Price, $2.00. This excellent volume, written by a practical stockman of many years experience, is a pioneer in the field of grazing literature, written from the standpoint of the wise use of our National forests. The author has brought together in a very clear and readable form a vast amount of material which is of especial value to the forester who is concerned in any way with grazing. While it is written primarily for foresters, it will also prove of great value to practical stockmen, especially the chapters on Range Current Literature. 85 Management, Poisonous Plants, Symptoms and Remedies, and Diseases of Animals. Although the volume contains a large number of illustrations, the author has selected only those which apply to the text and render it more clear. The book is welcomed as a new and valuable contribution to the forester's library. The views of stockmen in regard to this book are well re- flected in a review which appeared recently in the Southwestern Stock Review : "Probably one of the best informed men in the United States on the subject of stock grazing in the west is Will C. Barnes, the author of "Western Grazing Grounds," who *way back in the '8o's was associated with Albert F. Potter in range ventures in both sheep and cattle up on the Mogollon mesa and Little Col- orado sections of North Arizona. Mr. Potter is now associate forester and in charge of the grazing branch of the forest ser- vice, while Mr. Barnes is inspector of grazing in the same service. "Mr. Barnes was raised on a cow ranch in California; ranged through that state, Arizona, New Mexico and Texas in the early days ; has been secretary of the Live Stock Boards of both Arizona and New Mexico ; has made special studies of range live stock problems throughout all of the western states in the interests of the Forest Service and the recent tariff board of the Taft administration, and is essentially the man to father such a book as Western Grazing Grounds. "This book deals with the vast ranges of the west in detail from the time that stock began to appear on them down to the present day. It shows the various methods of handling stock as practiced in the different sections of the west; discusses the problems of range control ; by text and illustrations treats of the poisonous plants, predatory animals and stock diseases of the range, giving preventatives, remedies and other valuable in- formation concerning them ; gives figures on costs of running stock in the Avestern states, and in fact is filled with just the kind of information that every sheep and cattle man wants. Western Grazing Grounds is also an excellent text book for the man new to the west and makes excellent reading for any- one at all interested in the subject." R. C. B. 86 Forestry Quarterly. The Chestnut Blight Fungus and a Related Saprophyte. By P. J. and H. W. Anderson. Bulletin 4, Pennsylvania Chestnut Tree Blight Commission. 1913. Pp. 26. During the scouting operating in Pennsylvania to discover the extent of the Chestnut Blight, a fungus at first diagnosed as the true blight fungus (Endothiu parasitica) was found in the south western counties quite beyond the affected areas. Strangely enough it was doing no serious damage, and the question arose as to the cause of this phenomenon. Careful cultural studies conducted by the authors have shown that this fungus named by them B. virginiana behaves differently from the true blight fungus on certain artificial media. These differences and certain minute morphological differences are so constant that no doubt remained that two distinct species were in question. This has been one of the rather infrequent instances in which the settlement of a fine taxonomic point has had a direct and immediate bearing on economic operations. Since this article went to press the home of B. parasitica has been located in China. It is worthy of note that our authors were not drawn into erroneous theoret- ical deductions as to the origin of B. parasitica based on its very striking resemblance to B. virqiniana. J. H. F. The Blights of Coniferous Nursery Stock. By Carl Hartley. Bulletin 44, U. S. Department of Agriculture. Washington. D. C. 1913. Pp. 21. This paper gives a satisfactory account of several blights oc- curring in coniferous nursery stock. Damping-off diseases are ■not included. They are restricted mainly to seedlings under two months old, and have already been more or less thoroughly in- vestigated. The most important of the blights studied is sun scorch. The loss from this cause is often very great, especially on sandy soils, in soils lacking in humus, in crowded beds, and in raised parts of beds. Watering, shading, and avoidance of crowding are successful preventive measures. Other causes' of blight are winter-killing, mulch injury, and various fungus di- seases, for all of which more or less effective preventives have .been tested and are recommended. J. H. F. Current Literatu^re. 87 Biographical Records of the Graduates and Former Students of the Yale Forest School. Compiled by the Yale Forest School, assisted by the Class Secretaries Bureau. New Haven, Conn. 1913. Pp. 350. This volume is of interest through the very large share which graduates of the Yale Forest School have had in the develop- ment of the Federal Forest Service. A short historical sketch of the School is given in the begin- ning. It was opened in 1900, following a private endowment of $150,000, with seven regular students and a staff of two in- structors. Froqi its establishment it was a graduate school with a summer school for rangers, teachers and others, held at Mil- ford, Pa. The attendance rose rapidly, with an enrollment of 31, 44, 66, 63, in the years 1901-1904. In the latter year the Junior course was lengthened by the addition of a three months' field term in the summer, but with the work distinct from the ordinary summer school course. In the following year, the work of the Senior class, previously held at Milford, was transferred to virgin timber tracts in the south, and has since been so con- ducted. The same year, the National Lumber Manufacturers' Association established a chair of lumbering, with an endow- ment of $60,000, and an additional $40,000 in 1910. The sum- mer school was discontinued (1910), having had, since its in- ception, an average attendance of 18. In 191 1, the School gradu- ated its largest class (43), and since that the registracion has dropped, reaching 50 in 1912. The admission requirements are now quite high, eliminating the need of covering, after entrance, niany of the general science subjects basic to forestry study, with consequent increased time for technical subjects. The School has been endowed to the extent of over $400,000 in cash, and in addition has received various gifts in the shape of buildings, libra- ries, herbaria and equipment. The staff numbers 5 regular in- structors in forestry, in addition to men from allied depart- ments and special lecturers. The bulk of the volume is devoted to individual biographies arranged by classes. The enrollment from 1900 to 1912 included 402 names, of which 286 received the degree of M. F., and 14 certificates. Of the graduates, 57 per cent, are now engaged in government forestry (81% Federal) 7 per cent, in private forestry practice, 11 per cent, in educational work and 8 per 88 Forestry Quarterly. cent, in lumbering. In addition to the 139 Yale foresters now in the U. S. Forest Service, some 80 others were formerly so employed. /. H. W. Report of the Forest Bmnch of the Department of Lands of the Province of British Columbia for the year ending Decembei- SI, ipij. Victoria, B. C. 1914. Pp. 61. The cutting and manufacturing of timber is the greatest of British Columbia's industries. One-half the industrial capital of the province is invested in the lumbering and wood working business, and from forests is derived one-half the pay-roll of the province. It is estimated that one-half the standing timber of Canada is situated in British Columbia. Recognition of the importance of the forest wealth to the people of a province largely non-agricultural in character led to the passing two years ago of a Forest Act which provided for the establishment of a Forest Branch with complete charge of the administration of the timber lands. The organization of the Branch not taking place till late in 1912, this, though the second report, is really the first state- ment of the administration. Of the provincial area of some 250 million acres, 150 million are under forest administration. This is divided into 11 units, with all the various lines of forest work in a specified district, such as supervision of logging operations, scaling, collection of royalty, timber examinations, land classification, construction of permanent improvements, and protection of forests from fire, under the direction of one man. The permanent force in 1913 numbered 154, of whom 43 were clerks. For fire protection, the additional temporary force comprised 286, which was augumented by 50 more from the permanent force. The 11 administrative units varied in size from 5 million to over 36 million acres ; the ranger districts from 2 to 11 million, and the individual "patrol" territory from 350,000 acres to over 3 million acres. About II million acres have been taken up by lumbermen un- der grant, lease or license. From this', in 1913, the total forest revenue (rentals, bonus, royalty, taxation) was $2,999,328, of which $2,832,788 was collected by the Forest Branch. The re- maining $166,540 represented taxes at 2 per cent on 922,948 acres of private timber lands with an average assessment of $9.02 per Current Literature. 89 acre. This large forest revenue represents $6.63 per head of population of the province, as compared with 79 cents in On- tario and yy cents in Quebec, the two next leading lumbering provinces. The expenditure of the Forest Branch was $250,000 for ad- ministration, and $285,000 for forest protection fund, of the lat- ter only one-half being contributed by the Government. The returns in connection with the collection of the above revenue show a cut of about 1,457 niillion feet, board measure; with the inclusion of material (free of dues) used in railway con- struction the total would approximate 2 billion feet. In all, 794 logging operations in progress were inspected. About one-half of these are in the Coast district, using steam, and running most of the year; the remainder, in the Interior, are mostly fall and winter operations, using horses. The Coast operations produce about three-quarters of the total. The number of mills is about 425- The home consumption is less than one-fifth of the total pro- duction. The markets for manufactured logs are the Canadian prairies, United States, eastern Canada and overseas. Of these the Canadian prairies are the most important, taking about 60 per cent of the cut, and using all grades. Export to United States consists in a small quantity of cedar shingles for the mid- dle West and cedar finish for the New England States. The same products are shipped in small quantities to eastern Canada, as also a little high grade dimension material of Douglas fir. The cargo trade is small, some 3 or 4 mills shipping about 50 million feet, mostly to Australia, Great Britain, South America, China and Japan. The export of unmanufactured logs is forbidden, except from some early Crown-granted areas. These exported last year some 58 million feet, mostly for shingle manufacture in Washington. The total value of unmanufactured logs, poles, piles, posts, ties and props exported from the province in 1913 was $1,321,640. The smaller unmanufactured products are shipped largely from the Cranbrook and Nelson districts, and mainly to the interior provinces to the east. The pulp and paper industry has made a beginning in the province, the export totalling about 3 million dollars last year. The Powell river mill with a capacity of 225 tons of paper daily 90 forestry Quarterly. ships largely to the northwestern States; while the second mill on Howe sound, produces 40 tons of sulphite fibre daily, most of it for Japan. In addition to the regular field work incident to administration, the Forest Branch during the past year has conducted reconnais- sance work covering over 12 million acres. This has included land tributary to new railroads ; unknown timbered regions of the north, particularly the Nation lakes, Omineca, Nass and Bella Coola valleys; and the valleys of the Okanogan, Colum- bia, Kootenay and Kettle rivers of the more settled districts of the south. The report includes 18 summarized descriptions of areas covered by the different parties. As distinct from this reconnaissance work, special detailed ex- aminations covering 662,280 acres were made. By statute, land carrying timber in excess of 5,000 feet east of the Cascades, and in excess of 8,000 feet west of the Cascades, is not open for sale or pre-emption. All expiring timber licenses or leases remain under reserve until examined by the Forest Branch, and all pre- emptions and applications for purchase are referred to it by the Lands Department for field examination. In this way injudi- cious settlement on non-agricultural land and fraud are prevented. The report on forest protection for the year, unusually favor- able climatically, is ver}-^ gratifying. A total of 578 fires was re- ported attributable, 25 per cent to campers, 19 per cent to rail- way locomotives, and 10 per cent to railway construction. The total area burned over was 10,270 acres, classified as 5,835 acres of merchantable timber, 1,900 acres of valuable second growth, and 2,535 acres of slash. The damage was estimated at $18,354, viz., standing timber $4,387; logs on skidways, $12,084; and other property. $1,883. The total expense of fire-fighting was $8,930. Of the 578 fires, 420 were extinguished by the regular force without extra expense; 300 were extinguished in an in- cipient stage (less than ^ acre) ; only 80 fires reached serious proportions (over 10 acres). The permit >ystem during the closed season. May i to Oc- tober I, again justified itself. Nearly 12,000 permits to bum over 31,000 acres were issued; 95 per cent of these, totalling one- half the area, were for clearing land. Of the total, 17 escaped control. But 2 of the forest fires of the year were due to clear- ing land without a permit. Cnrrent Literature. 91 The fire hazard along railway construction has been controlled for the first time in the history of the province. The right of way cleaning is covered by the Railway Act. The slash situa- tion as regards the neighboring areas of Crown lands, which are logged free of dues by construction contractors, has been met by requiring the Railway Companies to take out permits for speci- fied areas, these permits requiring disposal of the debris by the companies as stipulated. The Forest Branch in this matter does not deal with the contractors. In all, 90 of these permits were issued, covering cutting on 138,276 acres. Some 1800 miles of railroad were under construction the past season. Voluntary slash burning by lumbermen aggregated some 10,000 to 15,000 acres in 191 3. As a result of the weather conditions the protective force were enabled to complete an unusual amount of permanent improve- ment work. This included 1200 miles of trail, 360 miles of telephone line, and 10 ranger cabins. The Forest Branch in co-operation with the Commission of Conservation for Canada has in progress a general survey of the forest resources of the province, the work to be completed in two years. A system of control of the range for grazing is also foreshadowed. The province is to be congratulated on the very considerable progress it has made in such a short time toward a businesslike administration of its timberland resources. Not only does this augur well for the prosperity of British Columbia, but in time must have its effect on the less progressive administrations in the east. J. H. W. Durch Konig Tschulalongkorns Reich. By Dr. Carl Curt Hos- seus. Strecker und Schroeder, Stuttgart, 1913. Pp. 219 4°, 125 illustrations and map. This is an elegantly printed record of a botanist's first ex- ploration in Northern Siam. It is not a systematic discussion of country or flora, but a rather diffuse account in detail of a journey or journeys with all its minor incidents, and the main interest is in these incidents. Floral descriptions are interspersed. Of most interest in this latter respect is the ascent of two moun- 92 forestry Qimrterly. tains, the Doi Sutaep, altitude 5500 feet, and Richthofenpeak, 8,350 feet, in which the various forest types from the tropical to the temperate zone are passed. In the first case. Teak and Albizzia, the former the main commercial timber, form the im- portant forest of the lower levels, mainly on south and west exposures, to be followed on the other exposures by what the author terms the Dipterocarp-hill forest, formed mainly of Dipierocarpiis laevis and turhinaUis, which is bled for its oil. At about 2,000 feet a new type is entered, characterized by lianas' and other climbers, absent in the former type. Here a Salix, a Juglandacea ( Bnglehardtia spicataj, Thunbergia, etc., are found. At 2,500 feet a mixed oak forest is entered [Quercus LindleyafW; lineata, Jimghuhnii, oidocarpa (deciduous), with chestnut (Castanopsis indica), a variety of leguminose trees, and the Magnoliacean Michelia Champaca, with many others. At about 3500 feet, pine forest appears (Piniis Khasya) of excel- lent development, which becomes pure. At 4500 feet the pine is replaced by a dense evergreen forest of oak (Quercus incana and JungJnihnii) with some other species; and at about 5.000 feet the only known ( ?) Asiatic species of Prunus, Hosscusii appears. Above this, Theaceae, Ericaceae, Euphorbiaceae, Myrtaceae and Quercus species form an inferior growth, which on south ex- posures reaches hardly over 25 feet, interspersed with grasslands, which the author refers to as result of fires. For the explorer in tropical lands many valuable suggestions are given. The illustrations are not always of the best : a map showing the location of the most valuable teak forests shows that North- ern Siam has perhaps the most extensive forests of this species. B. E. F.

The Blights of Coniferous Nursery Stock. By C. Hartley. Bulletin 44, U. S. Department of Agriculture. Washington, D. C, 1913. Pp. 21. The writer summarizes as follows the blights most common in nurseries: 1. Sun scorch. — The most common summer trouble which is caused by excessive water loss. Successful preventive measures are watering, shading, and avoidance of crowding. 2. Winter killing. — Due to tops of plants drying out when soil is frozen. Preventive measures most used consist of a light straw mulch and windbreaks. 3. Mulch injury. — Killing of tops through mulching may be prevented by avoiding heavy, close mulches. 4. Needle diseases. — There are a number of needle-destroymg fungi, which so far have done little damage in nurseries in the United States. Bordeaux mixture spray will prevent damage from any of them. 5. Red cedar blight. — Common on red cedar seedlings and transplants. Causes and methods of prevention are unknown.

FOREST GEOGRAPHY AND DESCRIPTION. Generally speaking the forests of Asia- Forests tic Russia are confined to the mountains of of Caucasus and the northern part of Siberia. Asiatic Russia. The interior country is too arid for forest growth. Conifers are more important in the north while the hardwoods reach their best development in the mountain valleys of south- western Asiatic Russia. Among the latter, beech and oak are most important commercially although walnut, birch, elm, maple, ash, linn and poplar also occur. Pine, spruce and fir are the important conifers. Exploitation has been confined almost entirely to the shores of the Black Sea and northeastern Siberia. From both of these sections ship transport is comparatively easy and supplies are sent at a low cost to the nearby markets. The vast softwood wealth of western and central Siberia has as yet been scarcely touched. Since the rivers drain north, transport must be through the Arctic Ocean and the summer is so short that a vessel can rarely make a round trip from England or Holland in a year. Unless cheap railroad transportation to the south can be secured the forest wealth of northern Siberia must remain uncut for some time to come. K. W. W. Aus Rnssland.

The three main types of forest are those in which pine is the predominant species, the spruce types, and a mixed hardwood type. The author subdivides the pine types into three main sub types with site classes in each. There are only two important spruce types. The principal timber trees comprise no different species, among which pine, spruce, oak, elm, basswood and boxwood are the most important commercially. Satisfactory reproduction can be secured whenever proper at- tention is paid to the light requirements of the species to be re- generated and the seedlings do not have too much competition from grass and weeds. The report from which this article was prepared was made for the Imperial Russian Forest Institute in 19 13 by a forester especially delegated for this jjurpose. It is to form the basis for the future forest policy for Transcaucasia. K. W. W. Aus Russland. Forstwissenschaftliches Centralblatt, Dec, 1913. Pp. 651-657- BOTANY AND ZOOLOGY. The range of Polyponis dryadeus is Root Parasite probably co-extensive with that of the oak of in Europe and America. Many species of Oak. both red and white oaks are known to be susceptible. The virulence of the parasite does not seem to be very great, as vigorous trees usually with- stand attack. A white mottled sap rot of the roots is produced which later involves the heartwood, but which does not extend up into the trunk beyond the soil line. It is here, at the surface of the soil, that the fruiting bodies are formed. The study is of interest because it adds to our meager knowledge of root di- seases, and because it establishes the fact that the stem heart rot ascribed by Hartig to P. dryadeus is due to an entirely different fungus, namely P. dryophilus.

Investigations conducted by the author Heart-rots in 191 2 on the condition of the oaks in of the Ozark National Forest and elsewhere Hardwood Trees, resulted in finding twenty different kinds of heart-rot. Six of these have been for the first time associated with the producing fungi, and an ac- count of three of them is given in this paper. The number of affected trees in some districts is very great — in one instance up to 64.8 per cent of some thousands of oaks that had been felled for commercial purposes. The infected trees were as a rule old trees, and the fungi had gained entrance in general through fire-scars. "So marked is this association of fire-scars with heart-rots in the Ozarks that one could tell the areas in the forest which had been most frequently burned over from the per- centage of trees affected with heart-rots." The three types described are: (i) a pocketed or piped rot of oak and chestnut caused by Polyporus pilofae Schw. ; (2) a string and ray rot of the oak caused by P. berkeleyi Fries ; and (3) a straw-colored rot of oak caused by P. frondosus Fries.

Chicago, and the present paper is the first of a series of articles to be published on the subject. They find that chimney smoke is only slightly toxic to the seedlings of sweet pea. 500 times less so than the smoke from a loosely rolled paper cigarette. Injuries from coal smoke are generally attributed to tars and oxides of sulphur, while reduced carbon-bearing gases have never been considered as a factor. The authors think, however, that carbon-bearing gases, especially ethylene might be in sufficient concentration to do in- jury and still be in too small quantities for detection by chemical analysis.

So far as known, there is in nature no special absorbent for ethylene, also no cycle for the gas as there is' for carbon dioxide and oxygen. Having no estimate of the total additions to the atmosphere from the sources indicated above, one cannot calculate whether accumulation up to the danger point is likely to occur. One factor that favors the effectiveness of the oxides of sulphur as plant poisons in the open as against heavy hydrocarbons is their great solubility- in the plant cell which would lead to their accumulation even under great variation in atmospheric concentration, whereas the heavy hydrocarbons would accumulate to a far less degree and varia- tions in concentration greatly reduce their injurious effects.

Goddard is one of the latest investiga- Soil tors to attack the much debated question of Fungi. the power of non-mycorhizal fungi grow- ing freely in the soil to fix free nitrogen. Eighteen species were isolated from samples of garden soil and grown on culture plates. Seven of them were the same as those found in forest soil by investigators in Holland. It ap- pears that, unlike bacteria, these fungi are rather uniformly dis- tributed in the soil, at least to a depth of about six inches. Most of the fungi studied were taken from three plots; one of which was untilled and unfertilized, one well tilled but unfertilized, the other both well tilled and well fertilized with stable manure. The fungous flora, however, did not diflfer materially in species or abundance in the three cases. The most abundant in all of the plots were members of the genera Miicor and Fusarium. The author made tests of some 14 species and none of them showed any power of assimilating free nitrogen when grown in nitrogen-free media. In looking over the literature of tlie problem, however, one finds more evidence that soil fungi do I04 Forestry Quarterly. have the power of fixing free nitrogen than the contrary. Yet it is only fair to say that the tendency of the later investiga- tions with their improved methods of experimentation is towards conclusions like that of the present investigator. C. D. H. The Botanical Gazette, October, 1913, pp. 249-305. A scholarly study by Forstmeister Wag- Solar Energy ner of Pommerania of the power of the in the sun in the forest, deserves more than the Forest. brief mention which can here be given. Wagner starts out by showing the import- ant role which solar-energy plays in the growth of forests. This energy he seeks to determine quantitatively and qualitatively ; which, from the standpoint of silviculture has never heretofore been done. Of course, the solar energy on unshaded areas has been deter- mined. Wagner sums up the data along these lines and then, from the standpoint of solar energy directs his inquiry along four main lines: I. The influence of latitude upon crown formation, volume production, number of trees, basal areas and branch formation. II. The extent of sim rays in the forest, with special reference to Border Cuttings (Blenderaumschlage.) III. The absorption of solar energy in the green leaf and its relation to site and to volume production. IV. The measurement of light in the forest; results and prac- tical importance. Much of what Wagner writes about is of a physico-chemical character and yet it all has its direct application in practical for- est management. For example, his studies show that a pure stand of 130 year old oaks, "closed," and with the crowns al- most touching each other, passes half of the red light waves, on which, he has previously shown, growth energy chiefly de- pends. Poor soil conditions are evidenced by the presence of short light waves under the crowns. From this Wagner con- cludes that under the north German solar conditions, (pure stands of oak involve an unjustifiable waste of solar energy and Periodical Literature. 105 mean soil deterioration. A complementary species such as beech must, therefore, be introduced into the stand if half the solar en- ergy is not to be wasted. Wisely Wagner (unlike his namesake in Tubingen!) refrains from making world-wide deductions on inadequate premises or recommending his findings as being of universal applicability. Very rationally he confines the use of his spectralphotometer and, indeed, of all photometric methods in the forest, to the realms of research. In practice, e.g. in the marking of thinnings', the find- ings of investigators can be applied. The essential thing is to utilize the solar energy just as completely as possible by secur- ing the maximum of absorption in the crown cover. Besides this, the crown spread and hence the growing space of the individual tree must be larger in northern than in southern latitudes if all the solar energy is to be absorbed, since in northern latitudes the sun's rays fall less vertically. Of course, the exact grow- ing space depends also on age, species' and site quality. This adequacy of future crown spread is not always properly re- garded in marking, so that stands approaching maturity have often been too severely thinned in their youth. This means enforced isolation of crowns in mature trees ; often breaks in the crown cover with attendant loss of solar energy. Wagner has introduced a new aspect of Conservation: i. e. Conservation of Elemental Energy. That this energy is limited is a thought strange to even our era of conservation. In this line of research Wagner admits science has only made the barest beginnings. The solar energy and the composition of solar rays are inadequately known. The analysis of chloro- phyll composition is far from completed. Physics and chemistry have not yet, determined the exact chemical eflFect of light in the forest. Wagner concludes these exhaustive studies with the modest assertion that the future will see the study of solar energy play as important a role in forest management as it already does in medicine and in general technology.

In the last number of the Quarterly (p. Temperature 576) a paper by Livingston on Plant Coefficients Growth and Climate was reviewed. Now, in in collaboration with Mrs. Livingston, he Plant has advanced a step — several steps — far- Geography ther in consideration of the subject. The and authors point out that plant association Climatology. boundaries must be considered as peripher- ies of certain complexes of environmental conditions. Thus far, investigators of ecological conditions have been unable, successfully, to unravel the tangle of conditions which effect the success of organisms in a given habitat. These environmental factors are water, non-aqueous materials, heat, light and mechanical conditions. What makes the problem of distribution still more complicated is the fact that each separate component of the environmental complex is variable in intensity, in duration and often in quality, as well as variable according to the stage of development of the organism acted upon. The authors in the present paper deal with only one of the environ- mental factors, namely temperature. As is well known, the usual method of dealing with temperatures in their effect upon plant distribution is to add up all the degrees of temperature, above a certain limit, experienced by the plants during the frost- less period. It, however, seemed to the authors that the ap- parent value of temperature summations must rest upon some basic principle of physiology not indicated in the summations themselves. To this end the chemical principle of Van't Hoff and Arrhenius is employed, that is, within certain limits the velocity of most chemical reactions doubles or somewhat more than doubles for each rise in temperature of 10 degrees Centi- grade. This principle has been applied with general corrobora- tion to the functions of plants, since such functions are mostly chemical or at least dependent upon chemical reactions. For example, it has been found, beginning with resting buds, that in the case of the flow^er buds of plum, peach, apple and other fruits, the time required for blooming is reduced by one half for each rise in temperature of 10 degrees Centigrade. If the processes of growth and development do really exhibit temperature coef- ficients, it is plain that the study of environmental temperature factors should deal with these rather than with temperatures di- Periodical Literature. 107 reclly. or at least they can be used as a check upon the tempera- ture summation method. The latter plan the authors carry out. That is, they sum the normal daily mean temperatures of 106 stations in the United States for the period of the average frost- less season (the direct index) ; they sum the temperature ef- ficiences corresponding, respectively, to the normal daily means and to the adopted coefficient (2) for each 10 degrees variation (the efficiency index.) Then they plot both sets of tempera- ture indices on a map of the United States, and the map is then divided into areas by climatic lines in the usual way. To compare the two series of indices thus charted, the ratio of each direct index to the corresponding efficiency index was ob- tained, thus giving a ratio for each station. These ratios were also charted on a map. In a roughly approximate way the two methods are in agreement, since for most of the area of the United States they give results which agree within the limits of a plus or minus variation no greater than 5 per cent. For local areas, however, there are considerable variations — sufficient to negate the correspondence of the two methods on an area which one man would be likely to study in actual field work. The direct index (summation) is a measure of the duration of the tem- perature factor of climate, while the efficiency index (10 degree variation) is a measure of the intensity of the temperature fac- tor. Which of these more nearly approximates the measure of the temperature effectiveness of a climate, so far as plant growth is concerned, will no doubt remain for a long time undetermined. C. D. H. The Botanical Gazette, November, 1913, pp. 349-375. An extract from "Indian Engineering" Forest brings up a controversy as to the value of Protection forests on steep slopes. One school has to assumed that the roots of forest growth Hill Slopes. extend into the crevices of rock and there- by assist disintegration and erosion. The other school believes that the roots envelop the rock and soil masses and "tie them together as a cord would do."

The conclusion was reached "There is no doubt that in the first place they never io8 Forestry Quarterly. promote slips while deforestation frequently does." The re- viewer, however, has noticed an interesting exception to this rule in the French Alps where in a certain instance the forest acts as a sponge and tends to promote land slips by concen- trating a large weight of water upon a thin subsoil which slides upon the rock foundation. Here, one of the means of attack to prevent a land slide is to cut the forest. This is, of course, an extreme measure. T. S. W., Jr. Indian Forester, November, 1913, p. 551. SILVICULTURE, PROTECTION AND EXTENSION. Frombling contends that the uneven de- Root velopment of individuals in a dense crop Competition is not, as modern silviculturists claim, a vs. matter of root competition rather than of Predisposition. individual predisposition. For, he says, since the raw humus, which in time nor- mally is transformed into assimilable substance, accumulates in the dense stand under the protective shade, it furnishes ample food, and root competition can only be for food. Competition for room can also not be the cause of uneven development or thinning out of stands, for just the species with characteristic tap roots, oak and pine, which get their water supplies from the depths, thin out most surely, while on the other hand the species' with shallow roots, spruce, fir, beech, thrive and keep dense in close crown cover, although here root competition would be expected. He calls root competition a most dangerous term. Welche Rollc spielt die Wurzelkonkurrens im Haushalte des Waldes. Forstwissenschaftliches Centralblatt, April, 1913, pp. 170-175.

Dr. Endres' summary of the advantages and disadvantages of in- tensive and extensive management is very timely. Periodical Literature. 109 Naturally it goes without saying that all forest management is intensive as compared with agriculture because the yield per unit area is small and large tracts must be secured to have appreciable results. There is, however, a great difference in intensity even with schemes of forest management. Clear cutting foUov.-ed by artificial regeneration of pure stands is an example of extensive forest management and the bad results which have often fol- lowed this method have led to the demand for more intensive systems in which groups of trees and not whole stands are the unit of management. However, Dr. Endres points out that all the evils ascribed to the clear cutting system as applied to pure stands are not in- herent. The defects urged against it are that it leads to soil deterioration and increases the danger of wind and insect dam- age. Dr. Endres asks questions whether the latter evils are any more prevalent over long periods in pure even aged stands than in irregular stands. Alost of the present day troubles are with pure even aged stands but there is not the same detailed data as to insect and wind damage in irregular mixed stands because such forests are very rare at this time in Germany. Soil de- terioration in pure stands can be avoided in great part according to the author by refraining from opening up the mature stand preliminary to the final felling operations and by immediate re- planting. An argument often used in favor of an intensive system which produces mixed stands is that pure stands are unnatural. Pure, even aged stands occur in nature, however, over wide areas. Two illustrations familiar to all American foresters are white pine and lodge pole pine stands. The fact seems to be that tliere is wide range of adaptability. Some species reach their best de- velopment in mixture while others occupy large areas to the ex- clusion of other species. The most telling argument against more intensive silviculture >uch as the methods of Gayer and Wagner demand is the econo- mic one. While an increase in the cost of administration may bring larger revenues up to a certain point the forester must con- sider very carefully whether the greater expense necessary to carry out a "group" or "border" cutting will yield commen- surate returns in soil enrichment, more rapid growth, freedom no Forestry Quarterly. from damage, and greater adaptability to future market condi- tions. Summarizing, the author would point out the danger of over emphasizing the defects of extensive, cheaply administered meth- ods of handling pure stands by cutting clean and planting during the present admiration for more intensive silviculture.

Paul Buffault gives an interesting ac- Reforestation count of the forestation on the federal for- m est of Vierzon, based on a study of the France. work executed since the year 1670 when the forest comprised 294 acres of brush and openings, and 7,670 acres "entirely ruined and devastated either by fires or by the grazing of ordinary stock and sheep." At this time 89 per cent of the forest area was unproductive. In 1779, the openings only amounted to 3,358 acres, or 25.6 per cent of the entire area. In 1859, the blanks had increased to 4,077 acres, owing to faulty working plans. In 1879, with the excep- tion of 741 acres burned over, the blanks had practically disap- peared. This was the situation at time of the disastrous win- ter of 1879-80 when 2,362 acres of Maritime Pine reforestation was destroyed by frost. These openings were increased by the burning of 1,591 acres. In 1890, there remained about 2,718 acres to restock. From 1891 to 1904, 2,157 acres were re- stocked. During this period the total expense was on an aver- age of $23.56 per ha. or $9 per acre forested. The writer gives' in detail an account of the reasons for the failures which may be summarized as follows: Crowding b}- undergrowth, poor quality seed and drouth, rabbits, fire and lack of drainage. Of these causes for poor success in sowing, heather and imder- brush were the most disastrous. The plantations during the per- iod 1891-1904 covered 2,179 acres of which 1,326 was new work. The average success was 50 per cent for new plantations and 37.7 per cent for the maintenance of old plantations. The aver- age expense here was $5.64 per acre forested, or about one half of the cost of sowing. But the average cost of plantations for the entire forest has* been about $7 per acre ; this figure would Periodical Literature. ill be increased to $io if the value of the plants were included. The main causes of failure in planting have been excessive moisture, invasion by heather and brush, damage by game, (espe- cially stags), and drouth. Buffault concludes that direct seed- ing must be abandoned as too costly and because the results are too uncertain. On the other hand, the plantations give suf- ficiently satisfactory results to justify being continued provided the soil is first drained and cleared. Preference is given to Scotch Pine and Pedunculate Oak. Interesting experiments are to be carried on with important American and foreign species. T. S.

The controversy in regard to fire pro- Fire taction in the teak forests of Burma is Protection. continued by H. C. Walker. The main point at issue seems to be whether the damage caused by fire is sufficient to justify the cost of protec- tion. For example, Mr. Walker estimates that the average cost of protection amounts to $13.00 per square mile per year whereas the damage is but little over $3.00. He summarizcb his reasons for discontinuing fire protection in the moist teak forests of Burma as follows: (i) "The first reason is to avoid the deterior- ation of the growing stock which it has been proved that fire protection causes." (2) "The second is to divert the funds and the energies' which are now utilized on fire protec- tion to attending our forests." Mr. Walker makes a rather in- teresting review of the fire protection policy in Burma. In 1896, a large majority of the local officers were in favor of con- tinuing protection. In 1902, the four conservators "assuming the desirability of fire protection was beyond dispute, proposed to extend protection to all teak forests in Burma within the fol- lowing five years." This started a lively controversy and the scheme to extend protection was quietly dropped. In 191 3, it appears that the majority are now against fire protection. The results of the experiences in Burma are of significance to Ameri- can foresters. T. S. W.. Jr. Indian Forester, November, 1913, pp. 532-540. MENSURATION, FINANCE AND MANAGEMENT.

One or two points of especial interest shall, however, find men- tion here : The newer yield tables, leased upon a heavier degree of thin- nings have brought about a later culmination of the mean an- nual increment and with it of the maximum soil rent (financial rotation.)

(3) Yield tables are especially useful in (a) Forest Organization: as basis for choice of species and method of management; for deciding upon the most favorable rotation age as well as for judgment site and stand quality; especially for the estimate of the volume and increment of in- dividual stands.

These differ quite markedly from the prescribed practice for the State forests of Prussia promulgated on March 17, 191 2* since the communal conditions to be served require different treatment. Dr. Hemann believes that the regulation of yield should be by the stand method in conjunction with an area-period framework.

Opinions divergent from those of Dr. Hemann are expressed by Oberforster Dr. Gehrhardt in an open letter on the same subject. The matter is of too restricted interest to warrant re- producing it here, however, the discussion is quite illuminating as showing present tendencies in Forest Organization abroad. Among these is the insistence that so specialized a subject as working plans be placed in the hands of a Central Bureau of Forest Or- ganization rather than left to each Forest Supervisor. As Dr. ]\Iartin has said : "The assumption that the Forest Supervisor can make the working plan for his forest in a manner satisfying the demands of the present day, can only come from those persons who do not know sufficiently the far-reaching significance of working plans."

This, in the face of treated beech ties lasting 30 years (in France), would speak against the metal tie. But there are other advantages from metal track which the author does not bring into his calculation. Hk)lzschwelle oder Eisenschwelle.

Oberforster Miiller having delved in the History archives of his home city, Leipzig, tells of a most interestingly of the history of that City Forest. city's forests. These are now comprised chiefly in the two royal Saxon "reviers" Burgaue and Connewitz, a total of 2,412 acres. Originally the major portion of these woodlands belonged to local monasteries; but the Reformation ended this and gradually possession passed to the city of Leipzig. The first survey of the city forests was made in 1563 by di- vision of the area into triangles and the measuring, on the ground, of the base and altitude of each (triangulation!). The survey also included a rough description of the component stands. The need for better bases of yield determination led to a resur- vey in 1714. Again, triangles were used to calculate areas. Care- ful descriptions of the forests formed a part of this survey. The boundaries were fixed accurately for the first time in 1597- Stones and scribed trees were used as monuments, the latter only till the eighteenth century when, for greater perma- nency, stones were substituted. The completion of the bound- ary work in 1597 was followed by an inspection on the part of a Commission appointed by the City Council. A protocol tells of Periodical Literature. 121 this inspection and of how more ma jorum, the celebration-dinner ended in one local nobleman and the parish pastor becoming com- pletely inebriated. These forests were then and are still, comprised almost wholl}- of hardwoods. The need of wood for fuel and of larger sizes for construction timber (oak), naturally led to a system of Cop- pice with Standards. Though a sustained yield was not always possible owing to the exigencies of frequent war-times, the stands seldom suffered for want of intelligent care. Always' there was the realization of what was needed to improve existing conditions in the forest, and the striving for this ideal. From the administrative standpoint the Leipziger forests are most instructive. The monasteries called the forests' silva or mirica or, if coppice, rubetum and virgultum. The forestarius (hence our forester and the German forster) had charge not only of the sik'a but of all that was foris with respect to the monas- tery, including ponds, meadows, etc. The title of forestarius or Forster was continued under the city administration. One of the Forster became in the i6th Century an Oberforster (present title of all German supervisors) and, because of this headship, was made mounted with all that this signified in improved social standing. Regulation of the yield was by area, the aim being to cut an equal area annually. As early as 1538 this principle was an- nounced. At first this area was merely determined in amount, later, 1617, it was also distributed on the ground according to the ages of the component stands. The resurvey of 1714-1716 resulted in a complete working plan based on area with a 20 year rotation for the coppice. Regeneration of the stand was by natural means. Gradually the coppice began to deteriorate and, in 1726,, first mention is made of artificial restocking of fail places and of unthrifty stands. But not till fifty years later was anything really accom- plished in the way of planting. In 1804 a new working plan was' prepared which marks the beginning of a new epoch in forest management. The author, however, ends his essay with the close of the old order or about the time of the battle of Leipzig, too years ago. "Ztir Geschichtc der IValduiiaen der Stadt Leipzig."

The various semi-popular texts on forestry Forestry Books which have recently appeared, among for which may be cited Graves' "Handling of Laymen. Woodlands," Hawley and Hawes' "For- estry in New England," and the forthcom- ing book on "Elements of Forestry" by Moon and Brown (all published by John Wiley and Sons, N. Y,), lends especial interest to the review by Dr. Mueller of Schiipfer's "Outlines of Forestry." It seems that, in Germany, interest in forestry is spreading among laymen owners of forest property. For them, primarily, this compendium is designed. Aside from a brief introduction on the economic importance of forests and forestry, the book is, therefore, confined to the subjects of forest production and forest management, omitting forest policy, history and administration as irrelevant to this purpose. The reviewer rather criticizes this omission since even the layman should be acquainted with the elements of these important phases of forestry. On the whole, though, he adjudges the book as a distinct success. "Grundriss der Forstwirtschaft." Dr. V. Schiipfer, Professor of For- estry at the University of Munich, pp. 268, plates 53.

Associations At this stage in our development Dr. von of Fiirst's article is very timely because our German Foresters, own Society of American Foresters can undoubtedly learn much from the history of similar organizations abroad. The German "Forstverein" as newly constituted has now been in existence since 1900 and its present thriving condition is evi- dence that it is filling a real need in a satisfactory manner. Prior to its formation there was an annual gathering or Congress- of German foresters but through lack of a permanent organization these meetings were not as effective as they have since been made. There was no continuity of policy, little was accom- plished in the way of standardization, and the lack of funds created deficits which were hard to meet. As early as 1881 Dr. Danckelmann proposed a permanent or- Other Periodical Literature. 133 ganization but preliminary education was necessary before the idea secured general acceptance. Since it was not until 1897 that the "Forstverein" was really launched in Frankfort a. M., "Aus dem Walde" was made the official organ and a membership of 244 enrolled. At the forest congress of the following year the movement was given a truly national scope by the enrollment of 1,100 members and by the appointment of a directorate of 28, composed of 16 delegates at large, 8 from local forest organiza- tions, and 4 from forest schools. This number was later in- creased to 55 by adding more members from the forest schools and from the ranks of the private practitioners. The functions of the board of directors are to choose the offi- cers', decide the themes, and in general legislate for the associa- tion. For each meeting two subjects are chosen for discussion. One of these is silvicultural and the other economic, as for in- stance: 1905: — Forest aesthetics and private forestry; 1904: — The humus question and the taxation of forest land. In addition to the wide discussions which the annual meetings afford important standardizations have been effected in German forest practice through the agency of this organization. Further- more projects of national scope have been carried through, like the collection of forest statistics so that the Proceedings have become records which even,- German forester needs. K. W. W.

NEWS AND NOTES. For the first time the Western Forestry and Conservation As- sociation held its annual meeting in Canada at Vancouver, B. C, December 15 and 16. This association has been a most import- ant factor, not only in timber protection, but in moulding public opinion. At the meeting, reports of progress made in the five States of the West v^ere given, and, in addition, a large share of the time -was devoted to the discussion of problems pertaining particularly to British Columbia. Practical questions were dis- cussed during the two days' session, participated in by timber- land owners, forestry officials and railroad officials, on both sides of the line. Fire protection in all its phases was the principal topic, involving modern methods for fire-prevention, fire-fighting, and communication in the forest. The session was brought to a close by a banquet given by the British Columbia lumbermen. It was stated at the meeting that "The best single result of the 1913 fire season has shown that systematized co-operative effort at an insignificant cost per acre, or per thousand, can reduce our forest losses of an average year from four or five million dollars to about as many thousands, on the twenty million acres of tim- ber lands controlled by the lumbermen forming this association." There are now thirty timber-owners' associations in the United States, the members of which have got together to adequately protect from fire their combined holdings, which now total about 25,000,000 acres. In Canada, there is but one association of this kind, the St. Maurice Fire Protective Association. The Quebec limit-holders comprising this association have, by a self-imposed tax of one- quarter cent per acre, installed a fire protective system on their 7,000,000 acres of holdings. In 1913 over 275 forest fires were extinguished with practically no danger, proving, in the words of the members, that "The success of co-operative forest fire pro- tection has been estabUshed without a doubt." After the disastrous forest fires in 191 1 the Michigan State Forestry Department conceived the idea of organizing the Boy Scouts into a protective association. Last year 3,000 scouts were Nezi's and Notes. 127 enrolled in this work and extinguished 731 fires. The fire loss of $3,500,000 in [911 was reduced to $67,000 in 1912, and to $23,000 last year. The Forest Service of the Province of Quebec now employs a total of sixteen professionally trained foresters. Nearly all these men have received their professional training at the Forest School at Laval University, Quebec. During the summer of 1913, the Quebec Forest Branch had fourteen parties in the field, each in charge of a technically trained forester. The work undertaken by ten of these parties was a valuation survey of unlicensed Crown timber lands. Of such lands, there are approximately 125,000 square miles in the Province of Quebec. The Crown lands under license aggregate approximately 70,000 square miles. The revenue from these lands during the past year has aggregated nearly one and three- quarter million dollars. In addition to the ten parties engaged as above, four parties were engaged in an examination of licensed lands, to determine the boundaries of permanent forest reserves. It is the policy of the Quebec Government to segregate non-agricultural forest lands into permanent forest reserves as rapidly as the necessary infor- mation can be secured. The Canadian Northern Railway has taken a very progressive step in connection with the prevention of fire along its lines by the appointment of Mr. William Kilby as Fire Inspector. Mr. Kilby is to have general charge of all phases of the Company's fire protection work. This practically involves the creation of a new department in the Company's organization. This includes right-of-way clearing, fire patrols through timbered country, and the construction of fire guards through prairie sections in Alberta, Saskatchewan and Manitoba. The prosecution of these lines of work is required by the Railway Act and the orders of the Board of Railway Commissioners. The Canadian Northern is the first large railway company in Canada to organize a special department to handle fire-protection work. Experience has demonstrated that the best results in this class of work are secured by specialization. The example of the Canadian Northern might be followed to excellent advantage by other lines. 128 forestry Quarterly. A National Forestry Congress, similar to the one in 1906, will be held in Ottawa next January. This was decided, on the sug- gestion of the Premier, by the delegates to the sixteenth annual meeting of the Canadian Forestry x\ssociation. The Lieutenant-Governors of all the Provinces, members of Parliament and of the Senate, prominent lumbermen, and in fact everybody who is prominently identified and in sympathy with forestry, will be invited by the Premier to attend the congress, at which matters pertaining to the preservation of the forests will be discussed. Prior to deciding on holding the convention, the delegates waited on the government and submitted resolutions covering such matters as the extension of forest areas, more care in de- ciding what lands shall be opened for settlement, free distribu- tion of young trees, and that appointments in the forestry service be based on capability and experience. During the past year, much progress has been made in the province of British Columbia in connection with minimizing fire risks through the disposal of slash resulting from lumbering operations. In 19 13, according to the Provincial Forest Branch, about 20,000 acres of lumbering slash were burned in that prov- ince, and a much larger area would have been burned had it not been for an extremely wet autumn. On the Coast and in the Interior, several experimental areas were burned by the Forest Branch, which, also, in co-operation with the Department of Pub- lic Works', burned a great many miles of slash along public roads. Such inflammable debris constitutes a serious fire menace as long as it is allowed to remain undisposed of. The Forest Branch, in co-operation with private land owners, secured the burning of quantities of slash created by road and railroad construction through private lands. It was a condition of the charter of the railways' now building through the province, aggregating 1,800 miles in length through timbered territory, that where timber is taken from Crown Lands for construction purposes, the slash shall be piled and burned, scattered and burned, or lopped, according to the direction of the forest officers. This was done over an area of nearly a quarter of million acres. About one hundred and twenty timber sales are completed or under negotiation with private companies, both lumber and pulp News and A'ofcs. 129 companies, and brush disposal is an important provision of each timber sale contract. Specific information is being collected by the Forest Branch as to the cost of brush disposal, but it is too early as yet to make definite annoimcement of the results. The Massachusetts Forestry Association oflfers prizes for the revival of tree planting in the State, the prize to go to the town or city which properly plants this spring the greatest number of shade trees on its streets in proportion to its population. The prize is a novel one, consisting of the planting of one mile of street or road or an equivalent, by the Association, in the pre- cincts of the winner. Under the auspices of the National Lumber Manufacturers' Association a Forest Products Exposition will be held in Chicago April 30 to May 9, 1914, when the exhibits will be moved to New York and be displayed May 21 to May 30. Merritt Berry Pratt, deputy supervisor of the Tahoe National Forest, has been appointed assistant professor of Forestry in the University of California, in the new department of forestry to open next autumn. Frederick E. Olmsted announces the removal of his office from 21 Lyime Street, Boston, to 255 California Street, San Fran- cisco, where he will continue work as a consulting forester. COMMENT. An insert published with this issue is to correct a number of errors which have occurred in the previous volume arising from the use of an erroneous factor of conversion from metric into foot board measure. This leads us to make some observations' on points to be con- sidered when handling and especially when converting German figures into our measure. In the first place the forester should realize early that all his measurements (except in some special scientific work) are merely approximations to the truth and mostly averages. Hence it is ridiculous to attempt to be accurate to tenths, hundredths, and even thousandths. Fractions are al- most invariably unnecessary, a rounding oE to full figures is almost invariably preferable, and often a rounding off to tens, hundreds and even thousands is nearer the truth than a statement to units. For instance, a statement of the forest area of a coun- try to units is really ridiculous, for there is no survey accurate enough to permit such a statement. Here accuracy to thousands of acres will convey to the reader better than a more detailed figure the status of things. To be sure, when a single forest property is concerned in a commercial transaction, it is quite a different matter. Still more ridiculous may become attempts to state with pains- taking accuracy relationships, as for instance yield table state- ments, especially if expressed in board measure, say to the foot. Not only do we know that the original measurements are capable of widest variation, but the variety of standards and log rules is such that a statement to hundreds and even thousands is all that we may accept as within the limits of attainable accuracy. Hence why burden the reader with the untruth contained in the closer figures? The painstaking accuracy is particularly ill advised when trans- lating statistics and other data from foreign measures into our own, for the simple reason that not only do the data themselves partake of the same uncertainty (although sometimes not to the same extent) as our own, but the conversion factors for prac- tical handling are. for practical reasons, shortened, introducing Comiueni. 131 an additional source of variation ; hence rounding off is still more justified. The rounding off", to be sure, must be done with judgment and such judgment is in part based on the use to which the figures are to be put, and the character of the measurement involved. If you convert kilometers into miles, it would be foolish to work out a translation to feet ; if tree heights are involved an approxi- mation to say five feet may still be acceptable when timber is in- volved, but if seedling growth is to be investigated the statement may be needed to even fractions of an inch. Still more judgment is required when attempting translations of assortments into other assortments, especially into feet board measure, for the foot board measure in itself is an entirely un- certain quantity when applied to the round log, depending on the size of the log and the log scale used. An article in this issue throws interesting light on this phase. Even the German figures, although they appear as definite cubic measure are variable in their meaning, since the standard of classification is variable from State to State, from time to time, and, to some extent, from species to species (taper!). German yield tables state quantities in cubic meter (at 35.336636 cubic feet) per hectare (2.471 14 acres); hence 14.3 will be the factor by which to multiply to make cubic feet per acre. The statement will be either for all wood including brush, or else only for "stout wood" or "timber wood" (derbhols), leaving out the brush with a dia- meter of 7 cm or less, i. e., including all the wood, branches as well,, of more than 2.7559. • -inches. Here we may stop to point out that it is of little if any value to set the limit for conversion at anything closer than the round 3 inch, for the quarter inch or so less does not approximate the truth any closer than the round figure, as will be readily admit- ted by those who measure diameters by two-inch classes. The brushwood per cent., which, of course, in the young age classes is 100 varies with age, species, and site, hence a direct translation from all wood to timber wood is not possible without a brushwood per cent, or else sawlog percent table. The "stout" or "timber" wood is by no means log material for mill purposes, but includes cordwood, etc. : it is merely the useful wood, as it would be with us where fuelwood is saleable. Lo- cality also influences the translation! 132 forestry Quarterly. What we would call loc/s in German usage must be over 14 cm (5.5 inch) measured at i ni from the smaller end; this we can readily round off to 5 inch at the small end, and if it were stated at 6 inch it would also not be egregiously wrong, and for East- ern conditions at least we could accept either as standard. Un- fortunately, few German yield tables contain this differentiation into saw logs, the statement of generally useful wood production satisfying the German forester. Even those yield tables which make this differentiation, like Schwappach's, do not state them in the simple board measure statement but, by percentage of the stout wood product, in a classification which must be understood, but is too complicated to elucidate here. The first thing that must be recognized is that it is absolutely impossible to construct one conversion factor that is applicable for tramlating a whole yield table into board measure, for th*e simple reason that from decade to decade, from site to site, from species to species the log per cent, varies. By using one and the same conversion factor we come to the evidently absurd result, that a lo-year-old, or 20- or ^o-year-old stand contains. feet board measure, i. e. saw logs. It is not even possible to secure a single conversion factor which can be used for the same species at the same age, because different sites will vary in their log production in a given time. We must then have different conversion factors for given conditions, the variation being due to a variable log content. Taking the Scotch Pine at 100 years, a usual rotation, the percentages of log material run from site I to site V: 71, 60, 36, 18, none. These percentages may be increased by material taken from thinnings and otherwise by a small amount. Taking Schwappach's yield table for Scotch Pine, we find that considering only the logs of the main stand on a first site no logs are found b. fore the 50th year. In the 50th year 9 per cent, of the stout wood produced are recorded and then from decade to decade the percentages are 20, 40, 53, 64, 71, 79, 84, 90, 90. That is to say after 130 years there is no change in log wood per 14.3 cent. The corresponding conversion factors run ( x per cent.) : .02, .04, .06, .074, .081. .09, .097, .104. Who will average these variables for translation of a whole yield table! We see then that a direct translation from cubic meter per hectare to Comment. 13^ board feet per acre is impossible except by referring to stated conditions. Yet it is desirable to have some data for rapid comparison, and such we may secure by averaging conditions, somewhat as follows. On better sites in old timber 60 per cent, of saw timber, and 40 per cent, for poor sites; for medium old timber (80 to 100 years) 50 and 30 per cent, respectively; for young timber (below 80 years) 40 per cent, on good sites and 20 per cent, on poor sites, keeping in mind that poor sites have often hardly any saw logs before 60 to 80 years. The corresponding con- version factors would then be reduced to say .05-.07; .03-.05; .02-.04 for the three different positions, using the lower figure for poorer conditions. Since most of the rotations of German forests circle around 100 years for statements of final yield, the likely saw log output found by using the factor .06 will probably hit the average of yields including thinnings, the average product at that age being 40,000 feet board measure, with a maximum of over 100,000 feet and a minimum of say 2,500 feet. The Biltmore bubble is burst ! We do not intend to convey any invidious insinuations on the enterprise by this alliteration, but only to express in the picturesque language which the director of the Biltmore school would be apt to use the cessation of a picturesque institution. Dr. Schenck has written himself its pic- turesque obituary, and in doing so has departed from the usual mode of obituaries, which are built on the maxim de niortuis nil nisi bene, by giving a slap to its graduates. He insinuates and complains that none of them "had made notable successes," that they "did not make any striking successes," that "none had be- come a live advertisement for the Biltmore forest school," and that they had to "start at the bottom everywhere." This last statement is indeed amusing. What did the director expect ? Did he suppose they would start at the top? We can name at least a half dozen of his men who have made good, and a few who are first-class and do not deserve the slap. It is our suspicion that they made good in spite of the school, which was carried on upon mistaken pedagogic principles, when introducing immediately to the practical field without previous fundamental or systematic theoretical training a motley crowd with various degrees of even general education. The lack of quiet study time alone would be 134 Forestry Quarterly. inimical to results. For such kind of introduction to a complex practical profession the time, one year, was much too short, and hence a heterogeneous mass of undigested information could in most cases be the only result, except for a few better prepared or exceptional men. What would have been an excellent post- graduate course after the theoretical work had been done was bound to become an impossible pedagogic abortion for under- graduates. The hunting after practicality before the theoretical foundation is laid is a fad, which will usually revenge itself by short dura- tion. In this respect as in the advertising line, Dr. Schenck tried to outstrip the American notoriety hunter by calling his school the "really American Forest School." He is right, there is "no more need of such a unique school as Biltmore ;" it was, as he now admits, "visionary." There were other reasons why the Biltmore school was not one to recommend itself, which it would lead us too far to enumerate; and there are perhaps other reasons for its cessation than those given by the director. Dr. Schenck in his obituary gives to the American public part- ing advice. He calls for an organization for the distinct purpose "of acquainting the American public with forestry as an Ameri- can business possibility," and in the same breath he declares, that private forests are "not maintained because they cannot be main- tained at a profit." He is right in thinking that the task in the woods of introducing forestry methods had better be entrusted to a logger who knows some forestry, but it will be well to have it done under the direction of a forester who knows some logging — without necessarily being a logger. It cannot be accentuated enough that the present-day logger in America is in an entirely different business from the forester. Dr. Joseph T. Rothrock, whom every forester on this conti- nent knows as one of the pioneers in the forestry movement, having reached his 75th year has resigned as a member of the Pennsylvania State Forestry Board, after serving on it for 20 years, although he is still hale and hearty, and active. Dr. Rothrock was originally a medical man, in which capacity he served during the civil war, then turning to botany and acting as botanist on various explorations, he l>ecame Professor of Bot- Co}iiinent. 135 any at the University of Pennsylvania. He also gave the lectures, endowed by the Micheaux fund, intended to popularize silvicul- ture, and, when in 1886 the Pennsylvania Forestry Association was formed he was naturally the man to become the leader of the movement. It was the first forestry association that could afford a paid Secretary, and send him through the State lectur- ing. It is not too much to say that the whole sane, consistent and persistent development of forest policies in Pennsylvania is due mainly to the efforts of Dr. Rothrock. He formulated the original legislation, which established the first governmental agency, and became the first head of the Forestry Division, and afterwards Forestry' Department. Long may he be spared to give his valuable advice to his State ! A very important and very sane re-adjustment of royalties for timber licenses has been embodied in a bill before the legisla- ture of British Columbia by the Minister of Lands, Hon. Wm. R. Ross. Those familiar with Canadian conditions will recall that six or eight years ago the provincial government of British Colum- bia disposed of most of their timberlimits under the license system, charging a uniform royalty per M feet of 50 cents ir- respective of location ; reserving, however, like all Canadian li- cense systems the right, on the part of the Crown, to change conditions. It is evident that a uniform royalty charge for all locations is unfair, and that an arbtrary right of one of the parties to the contract to change conditions is unfair to the other party and immoral, and, on the other hand, that a royalty which does not change with change in timber value is unfair to the people and unbusinesslike. The Minister of Lands, who was responsible for the estab- lishment, two years ago, of an efficient forest service, has boldly taken hold of the situation and solved the problem of equitable dealing in a most practical manner. In this bill the province is divided into three localities as regards timber dues: the coast territory, where 85 cents per M feet is charged, but only on the better grades, the lower being relieved of dues — a very wise dis- tinction: the southern Rocky Mountain district where 50 cents royalty is charged throughout, but by applying the B. C. log rule as against the Doyle rule, the discrepancy of values is somewhat 136 Forestry Quarterly. relieved; the northern interior, where conditions are still quite undeveloped and little activity exists carries a royalty of 65 cents. The government pledges itself for 15 years not to raise royalties for small dimension material, but there is to be every five years until 1955 a revision of the royalties on logs, namely by establishing the average lumber price and adding a certain per- centage of the increase, if any, above $18, the present price, to the royalty, namely 25 per cent, at the first revision and increas- ing percentages at each revision until finally 40 per cent, of the increase is added to the royalty in 1945. Grading applied in the Coast region is specially taken care of in the bill and a revision for such grading in ten-year periods provided for. While in this re-adjustment the government does not perhaps secure as much as would have appeared fair had it not in the first place made a disadvantageous bargain, we must consider that as fair a compromise as possible, doing justice to all parties con- cerned. It gives stability to the lumber business for forty years without fear of disturbances, and, while we miss provisions for improved forestry practice, at least the financial side of the government interest is better taken care of and changes to introduce for- estry methods are at least forshadowed. With this legislation, if enacted, British Columbia takes the lead in Canada in modern and efficient timberland administration, which by passing into the hands of a forest service promises a final forest management for their future. In the exuberance of his enthusiasm at having solved the tick- lish problem the Minister in a public address is misled into as- serting that the principle of such re-adjustment has never been enacted before by any other nation. In this the Minister is mis- informed. In Prussia the government rate, under which no timber is to be sold, is adjusted every three years.

Some time ago, I designed a range finder for lookout stations to be constructed entirely of metal. At present the accuracy and expense of such an instrument do not seem warranted. Therefore I have devised another range finder, which, while nnitp accurate, is nevertheless cheaolv and easilv constructed. ERRATA On page 137, volume XII read in 8th line: **strap iron" for "scrap iron;" in 19th and 20th lines: "minutes" for "feet." Upon the circumference of such a circle graduations of 30 feet or 15 feet can be accurately drawn.

'^^^ ^^^^ ttOTANICAI. By Lincoln Crowell. oakdbn. Some time ago, I designed a range finder for lookout stations to be constructed entirely of metal. At present the accuracy and expense of such an instrument do not seem warranted. Therefore I have devised another range finder, which, while quite accurate, is nevertheless cheaply and easily constructed. (See frontispiece.) It consists, first, of a wooden base frame ; second, of a disk of three-ply veneer or thin boards upon which a paper azimuth jircle is glued ; third, of an alidade made of scrap iron. The azimuth disk and alidade turn about a pivot fastened to the base frame. The disk is turned by means of a U-shaped iron rod, the ends of which fit into holes placed diagonally on the isk. When oriented, the azimuth disk can be secured in place jy clamps at the corners of the frame. The sights of the alidade are cut out with a hack saw. The azimuth readings are made at the right hand edge of the base of +he alidade adjacent to the slit sight, where a knife edge is filed jn a radius with the pivot. The most practical diameter for the azimuth circle is 20 inches. Upon the circumference of such a circle graduations of 30 feet or 15 feet can be accurately drawn. Five degree graduations are obtained by measuring their natural tangents along the edge of a circumscribed square, and by laying off the single degrees with dividers along the circumference of the inscribed circle. By this method the azimuth circle can be quickly and accurately drawn. . The paper disk and alidade are covered with a heavy coat of ^ shellac. When exposed to the weather the instrument is covered '"" by a box with a pitch roof. CO 138 Forestry Quarterly. To adjust the azimuth circle: 1. Determine the azimuth of a line between some point that can be seen from the look-out station and the range finder. 2. Sight on this' point with the alidade. 3. Turn the azimuth circle until the reverse bearing of the point coincides with the knife-edge on the alidade. 4. Secure the position of the azimuth disk by screwing down the corner clamps. Last summer, I constructed three range-finders on the plan of the one described, and so far they have proved very satisfactory. A MECHANICAL TREE PLANTER. By Forman T. McLean. A machine which will plant forest trees more rapidly and as well as a man with a mattock can do it, would be a useful instru- ment to foresters. The device shown in the accompanying dia- gram gives promise of doing this. It is an invention of Mr. N. P. Jensen, of Ephraim, Utah. It was tested experimentally at the Utah Experiment Station in the spring of 1913, and gave very satisfactory results. The machine is specially adapted to plant tap-rooted conifers on rough, brushy lands and burns, where hand planting, in holes dug with a mattock or spade, is the method usually employed. The tests made with the machine at the Utah Station were with 30 Western Yellow Pine, 2-year-old seedlings. They were planted in oakbrush chapparal, on a north hillside at 7,500 feet elevation. They are alongside an experimental plot planted by hand to the same species at the same time. The planting was done about May 15. The trees were examined in August, three months after planting, and at that time 28 of the 30 trees planted were alive and growing. They looked as thrifty as the hand-planted trees. The main advantage of the machine is its speed. The 30 trees were set by one workman in a half hour. This is about as rapid as two men ordinarily plant on similar ground, and was much faster than the planting on the experimental plot, to which it was compared. While the above showing appears favorable, the work was on entirely too small a scale to be conclusive. Several hundred plants were set on different experimental plots with this device in the fall of 1913. These plantings should begin to show results by the end of the field season of 1914. The operation of this machine is quite simple, as is shown in the accompanying diagrams. Fig. i shows the machinery ready to receive the plant. The roots are stnmg in the groove at A, made by the two blades at the base of the picture. The top of the plant projects into the flare at B at the top of the blades. I40 Forestry Quarterly. With the plant in place, the third blade of the machine, at C, is closed over the plant by raising the lever D. The machine is then in the position shown in Fig. 2. It is thrust into the ground with the foot on the tread H until the base of the flare, E, is level with the surface. Then the machine is rotated in a clockwise direc- tion, meanwhile pulling the lever F at the top of the machine to the handle at G. This opens the blades as shown in Fig. 3, and releases the plant. At the same time the rotating blades thrust soil in around the plant, and thus pack it firmly in a core of earth. Fic ^ F.g.3 A NEW MEASURING INSTRUMENT. By H. W. Siggins. The forester, in his daily work in the woods, frequently has the opportunity to collect odd bits of data or make measurements which might later be of considerable value to him if accurate. Often, too, he desires to have an occasional check on his ocular estimate. It is' out of the question for him to be carrying around at all times the several instruments required to make these va- ried observations. There is seldom a time, however, that a straight walking-stick would seriously discommode him. The idea oc- curred to the writer that a combination of the Biltmore stick, the Christen Hypsometer, and the Doyle rule in a single stick would solve the problem, since it would be very compact and at the same time would cover quite thoroughly the common requirements of a forester, not engaged in special detailed researches. Such a com- bination would enable him to measure total height, crown height, merchantable height, or the height of any point on the bole; to measure the diameter of the standing trees at breast height and the diameter of logs at any point; to determine the volume of logs, either by the Doyle rule or by the application of any form- ula; to estimate the volume of standing trees by measuring the diameter b. h. and merchantable height, allowing for taper, and then referring to the Doyle rule ; to make any measurements that can be made with an ordinary yard-stick. In pursuance of the idea, the Christen and Biltmore stick scales were carefully calculated to hundredths of an inch and tran- scribed to a suitable stick. The completed instrument consists of a round, hard maple stick, three and one-half feet long and shod at each end with a brass ferrule. The folding arms for the Christen are set in at points approximately 5 and 20 inches from the top. They consist of brass strips 2 x ^ x 1-12 inches, rounded at one end, and provided with a hole through which a nail is driven, hinging the blade like that of a jack knife. Brass seats are set into the wood behind the blades, so as- to allow them to open only to a position perpendicular to the stick. A notch on 142 Forestry Quarterly. one side of the slot in which the blade is seated and a nick in the blade facilitate opening. rr a) Co) A longitudinal section showing Christen arm (a) folded and (b) ex- tended; (c) is the brass seat. The distance between the two arms when erected is exactly 15 inches. At one side of the stick and along the lines' connecting the arms is marked the Christen scale, based upon the use of a lo-foot pole and a distance between the arms of exactly 15 inches. It is de- rived according to the formula: height of tree distance between arms height of pole scale distance height of pole X distance between arms or scale == , ■ , ^ — j— ■ height of tree The Christen, so constructed, is very accurate up to a height of about 50 feet, and is thus suited to the second growth found in this vicinity. If larger trees are to be measured the same de- gree of accuracy can easily be obtained to a much greater height by making slight adaptations. For instance, using a 15-foot or a 20- foot pole the reading can be made accurately to 75 or 100 feet respectively by multiplying the original scale reading i^ or 2. The capacity for accurate measurement could be raised to 100 feet by the use of a 30-inch distance between arms and a lo-foot pole, to 150 feet with a 15-foot pole, or to 200 feet with a 20-foot pole. Since the 15-inch distance between arms is much more convenient to handle in small growth, it might be advisable to put in both 15 and 30 inch Christen (using the same upper arm and putting the scales one on each side of the arms) where the height of trees to be measured varies greatly. If measurements are to A New Measuring Instrument. 143 be made in a country where lofoot saplings of weed species are not abundant, a hole might be bored in one end of the stick to receive a piece of chalk, thus providing a method of marking off a lofoot distance on the tree to be measured. If many measure- ments are to be made it would be profitable to use a bamboo rod, jointed in 10, 15, and 20 foot lengths. The scale for the Biltmore stick is printed on the side opposite the Christen arms, using the top of the stick as a zero point. In order to get the scale marks at the proper angle to be in line with the eye, the rule was fastened to a drafting board and the cross- head of a T-square placed against one side. A pin was placed in the shaft of the T-square, 25 inches from the far side of the stick, in other words in the position of the eye. The T-square was then shifted to points half way between the zero point and the point being marked. A thread running from a pin in the zero point, around the pin on the T-square, and thence to the scale point being marked, indicated the course which the scale mark should follow across the stick. The Doyle rule scale for 16- foot logs and the inches of di- ameter occupy the remaining Space on the stick. The 16-foot length was chosen because it is the easiest to reduce to all other lengths. It is to be noted that the Doyle rule is used on this stick because it is the accepted rule of the region. Any other rule which would fulfill local requirements could be used in its place. The scales were marked with India ink and the whole was then given two coats of shellac to render it water-proof and to protect the scales from defacement. The appended tables show the scales that were used. 144 Forestry Quarterly.

By Joseph C. Kircher. The writer has seen no recent working plans for private hold- ings, so that these cannot be criticised. In the Forest Service, however, there has been in the past a great deal of agitation for at least preliminary plans for all of the Forests. To accomplish this, an outline for a plan was prepared and submitted to Forest Supervisors'. The preliminary plan was to be based on this out- line. A number of these have now been written. A review shows them to be failures so far as the administration of the forest is concerned. On the other hand, the time spent upon them has not been wasted, since they bring together data which will be useful, in writing practical plans. The outline submitted to Supervisors called for complete infor- mation in regard to timber, silviculture, etc. A brief tabulation of the subjects, which is as follows, shows this. 1. Timber. Estimates, Descriptions, Forest Types, Timber Operations, Object of management, Silvicultural systems, Regulation of yield. Sales, Free Use, Record of Timber Business, Timber Reconnaissance. 2. Forestation. Policy, Areas requiring forestation. Methods and Species, Detailed Plan, Record of Operations, Nursery. 3. Investigations. A number of subdivisions were placed under each of these sub- jects. The outline for District 3, which included a number of tabulations, contained 23 pages. With such a formidable array of subjects before them, supervisors were naturally confused, for they could not see that much would be accomplished by the plans. The result was that most of the preliminary plans were simply routine reports, in which the really important points were lost in a mass of details. They were really long reports on past accomplishment. As preliminary working plans they have failed. 146 Forestry Quarterly. They were written, not with the idea of aiding in the manage- ment of a forest, but simply as a report called for by the District Forester. After being written they were promptly filed. For example, most of the plans devote much time to silvical and type descriptions and past timber operations. Of the future and of silviculture they say very little. In fact some of them say nothing of this. On several of the Forests working plans have also been made by specialists. These have for the most part also failed for the same reasons. An added reason for the failure of these plans •is that most of them were written with the idea of publication, instead of making them plans, which would actually aid in ad- ministration. Plans written so as to be interesting to the lay- man, will rarely be of actual practical value in the administration of a forest. The main reasons for the failure of past plans of the Forest Service are as follows : 1. They are long reports and largely silvical. 2. They give in detail unimportant considerations and often slight the important ones (Good silviculture). 3. They fail to take local and American conditions into con- sideration (Accessibility). 4. They are too academic. 5. They attempt to regulate the yield by scientific and mathe- matical principles, based on insufficient data without reference to local conditions. 6. They are not practical. I. They are long reports which are largely silvical. Most of the plans are very long. For the proper administration of a forest, plans must be short and concise since the man on the ground does not care to, nor has he the time to go through a long report to look up some point, say on policy, especially when the greater part of the report consists of silvical data. The im- portant facts and deductions may be hidden somewhere among unimportant details. The result is that the plan is not referred to when it should be. Instead, the Supervisor makes a guess at the point in question. Large parts of the plans consist of silvical data. Much of this Preparing Working Plmts. 147 information is known to every man who has been on the Forest for some time. The more technical part of it is not necessary for every day administration. For this reason local men get the idea that the plan contains mainly data which they cannot use. The result is that it is filed and seldom referred to. Plans to be of use must discard all useless data. The remainder must be a clear cut and concise statement of policy and facts which are essential in administration. It is not the object of the writer to belittle silvical data, because these are of importance. They, however, have no place in the plan proper, but should be separately filed or placed in the appendix for reference. 2. They go into detail and emphasize unimportant details and slight the important consideration. Plans to be practical should go into details on timber sale and free use policy and silviculture. Yet in the plans submitted, these points are often dismissed after being merely mentioned, while much space is given to silvical data, etc. Such data should be relegated to an appendix. In many of the plans policy and silviculture are disposed of in a page or two, while many pages are written on silvics, etc. This is undoubtedly a mistake, for it makes the plans useless. The difficulty seems to be in the out- lines which must be followed. Fortunately good silviculture has not actually been slighted in the field. 3. They fail to take local and American conditions into con- sideration. It must be remembered that the National Forests usually con- tain the most inaccessible stands in their respective regions. They consist of the timberlands which no one considered desirable before the forests were created, or else they would have passed into private ownership many years ago. This point seems to have been overlooked in many instances. For example, there are plans outhning cuttings, which because of the inaccessibility of timber cannot be made for many years. The consideration of markets has been largely overlooked also. It is a foregone con- clusion that without a study of markets an intelligent timber sale policy cannot be established. There is a further consideration. It is needless to talk of prac- tising forestry until cutting can be done. Until sales can be made, therefore, it is useless to dream of future receipts. 148 forestry Quarterly. 4. They are too academic, i.e., they fail to apply common sense and good judgment in regard to future management. Aside from the purely silvical discussions, plans have in most cases followed closely European ideas as expressed in books. The trouble has largely been that there was no system of Ameri- can forestry, and that plans were in many cases made by men of too little experience. The foundation of their forestry education has naturally been European practice. This has been so thor- oughly drilled into men that it takes a long time for them to get away from it. For this reason such books as Schlich's have been freely consulted in the preparation of plans. The following of European methods has been done at a sacrifice of sound business judgment. 5. They attempt regulation of yield by scientific and mathe- matical principles, based on insufficient data without reference to local conditions. Most of the plans attempt the regulation of the yield, although they are silent on its distribution. The favorite method is by volume based on mathematical formulae. The methods used so far have been nothing less than mathematical slight of hand. The basis of such calculations has not always been sound. Thus, in one case elaborate calculations have been based on timber estimates', which are perhaps 50 per cent, below the truth and upon increment measured on 200 trees in a virgin stand. It is the writer's opinion that the regulation of the yield on most of the National Forests is at the present time of little importance. The forests are pra-ctically all virg-in and forestry cannot be practised until many of the stands are cut. The annual cut should, there- fore, he based upon local conditions such as markets and accessi- bility regardless of -whether this cut -will be larger or smaller than one based on mathetnatical formulae. One of the standard Euro- pean methods may, however, be used as a check. 6. They are not practical, i.e., they do not work. All of the foregoing discussion tends to show that the plans are impractical for the administration of the forest. This is a fact which has several times been brought to the attention of the writer by Supervisors. If this is true, then a radical change in working plans is necessary. The time and effort spent upon past plans is, however, not Preparing Working Flatus. 149 wasted, since they bring together most of the data available in the files' of the Forest, so that they may later be used for working plan purposes, and further data may be supplied where the present plans show that there is a lack. Before taking up a proposed solution of the working plans, the conditions which are met on the National Forests and the Forest Service policy in regard to its timber holdings must be scrutinized. Based upon these two considerations a new work- ing plan system is proposed. The conditions to be met on National Forests may be consid- ered under three heads: i. Inaccessibility of stands, and large investments required to open up such areas. 2. Markets (local and export demand). 3. Large stands of over-mature timber. 1. Inaccessibility. For the most part the timber controlled by the Government comprises the most inaccessible forests in the country. For this reason it is difficult to place Government tim- ber on the market. In many localities, therefore, no timber can be put on the market until the more accessible private holdings have been cut. In other places, to bring the timber to market requires large investments and, therefore, large logging opera- tions. All of these conditions must be considered in connection with working plans. For example, if because of inaccessibility no timber can be sold from a certain forest for 10 years, it is useless for the working plan to designate certain stands for cut during this period. Or, if the Forest Service desires to sell tim- ber from a certain forest and must sell say 1,000,000 M. feet to justify an investment, it is useless for the plan to prescribe an annual cut of 10,000 M. feet, even if this is the increment plus the per cent, of growing stock which should be cut per annum to give a sustained annual yield. The question is not so much "What should be sold" as "What can be sold." It must be granted that to practice silviculture, cutting must take place in the virgin stands of the National Forests. If, then, because of inaccessibility, very large sales must be made to place timber upon the market, the plan of cutting must be such as to allow this. In other words, the annual yield will have to be es- tablished largely upon what can be and must be done, and riot upon the basis of a sustained annual yield. 2. Markets. A detailed study of markets is essential before a 150 Forestry Qtmrterly. working plan is attempted. This is necessary, since, if there is no market for timber, t"here is no chance for sales. Then again, if there are no sales on a forest and the Forest Service desires to make some, it must study markets to find out whether sales are •feasible. The character of the market, competition, etc., will have a direct bearing on sales, and, therefore, upon working plans. Markets are of two kinds — local and export. Local markets must first be considered. These ordinarily consume a very small amount of the timber. Whether they are small or large, the supply for local consumption must not be endangered by supply- ing export markets. It is, therefore, important to make a study of local markets, and to predict the local market for some time in the future. If, as is generally the case, there is a large surplus after the local market is satisfied, export markets must be con- sidered. A study of these is of importance, since, if the products of a certain forest cannot enter into direct competition in the general markets with like products from other producing centers, it is useless to try to make sales at the present time. On the other hand, a study of markets may show a very desirable logging chance and a good opportunity for a sale. The working plan should, therefore, recognize the market conditions which exist. 3. Large stands of over mature timber. It is desirable to re- place the large amount of virgin and over mature stands within the National Forests by young thrifty stands. For this reason it is more important to sell timber even if the annual growth is greatly exceeded than to hold the cut strictly to a sustained annual yield. An additional argument for the rapid cutting of the over- mature timber on the National Forests is found in the fact that the timber producing area of the United States is being constantly decreased. This will ultimately result in a timber shortage, which will probably not come, as supposed by some, as a sudden catas- trophe but in the form of a slowly diminishing supply, to which the United States will adjust itself in part. This condition can be met much more effectively by the National Forests with a young thrifty stand of timber yielding its full annual increment than with old deteriorating material. It is believed that the Na- tional Forests can, by extensive cutting of over-mature timber, be converted into good producers before the "pinch" is felt. Preparing IV or king Plans. 151 Forest Service Policy. The timber sale policy of the Forest Service, as expressed in Amendment 163 (of March 21, 1913) to the Timber Sale Section of the National Forest Manual (issued December i, 191 1) is as follows : "Sales of small amounts of timber are preferred and will be encouraged by every means possible. In no instance will more timber be sold under one contract than is necessary to cover the cost of improvements which must be constructed for its exploita- tion and to permit logging and manufacture under practical and economical conditions. Timber which can be practically logged under Classes A, B, and C sales will be reserved for operations of this size as far as such demand exists. Class D sales, where larger investments must be made and more timber handled, will ordinarily not exceed 75,000,000 feet in amount and five years for removal. "Where the inaccessibility of the timber requires very large in- vestments for railroads or other improvements, enough stump- age will be contracted to justify the outlay for these purposes and the size of operation necessary to make the enterprise feasible. The cutting period in such instances will be determined by prac- tical logging and manufacturing conditions. "There are no fixed limits as to the size and period of sales of inaccessible timber requiring expensive improvements. The prin- ciple of contracting enough to justify the outlay will govern in each instance. It will, however, seldom if ever be necessary to exceed 1,000,000,000 feet, or a cutting period of 25 years. "In lieu of the sale of a large amount of timber, the contract may specify that certain areas, in addition Reserved areas. to the stumpage purchased, will be reserved from sale until the termination of the con- tract and then offered for competitive bids. A reserve available to the improvements of the purchaser is thus held, while the terms under which it may be bought are left for future adjustment and will necessarily be subject to advertisement and competition in the regular manner. Such agreements to offer additional blocks for sale will be made only in accordance with the plan of manage- ment adopted for the unit or watershed concerned. This method will be used where acceptable to purchasers. It is preferred to the sale of larger bodies in the initial contract. In the management of watersheds or other units, the construc- tion of new and competing mills will be en- S table industries cou raged to such a number as can operate encouraged. for a reasonable period in accordance with prevailing standards in the industry. Pri- vate timber available for such plants, both as to situation and 152 Forestry Quarterly. ownership, will be considered together with accessible National Forest stumpage. A number of small mills is always preferred to one or two large plants; and wherever the accessibility of the timber and other local physical conditions permit, the development of the industry by small or medium sized operations will be strongly encouraged. "As far as practicable, the rate at which timber is sold from any unit will insure a reasonable operating life Reservations for for new mills constructed in connection future operations. with sales. Future sales to estabUsh mills can not be guaranteed, and the National Forest timber will not be administered so as to give particular mills a monopoly; but the amount to be cut from year to year will be regulated, so that established plants, if there are successful competitors for the timber offered, can be assured continued op- eration for reasonable periods." In accordance with this policy large sales are being made where timber is inaccessible and requires large investments to place it upon the market. This policy disregards sustained annual yield, but it is justified from a silvicultural standpoint, since without doing this no timber could be placed upon the market. It is also a sound business policy. The Proposed Plan.* The main difference between past plans and the proposed sheme for National Forests is that under the new system, the material is so arranged as to be more easily handled, and that the plans become actual plans of management, which are a live issue of practical value in the administration of the National For- ests. Forest management, sales regulation and systematic silvicul- ture will be carried on by means of: 1. Card records to be kept up to date by annual additions or corrections from the annual plan. 2. Annual plan by Supervisor. This should include any pro- visions which are necessary in the periodic plan. 3. Maps by specialists (including reconnaissance sheets). * This follows the informal district instructions to be tried out during 1914 before being put into effect ; these were prepared by the writer and Mr. T. S. Woolsey, Jr. Preparing Working Plans. 153 4. An appendix file to comprise all data on silvics, logging, etc. These to be filed by subjects and to be cumulative. 5. Preliminary plan to be made by specialists. 6. Final plan — not to be attempted at present. 1. The card records will consist of all data which are ordinarily tabulated. Tabulations are kept on separate sheets. They in- clude tabulations of areas of types, estimates of timber, sale costs, records of stumpage rates, minimum stumpage prices, timber cut and sold, limitation of cut, lumber prices, percentage of lumber grades, species, etc. These tabluations are kept to date by annual additions to the information. The information for the revision is obtained from the annual plan. 2. Annual Plan. This is made in winter by the Supervisor. It includes the following information: General conditions of the Forest, cost of handling sales, limitation of cut, minimum prices, proposed changes in silviculture manual, recommendations for silvical report, sowing and planting, timber sale policy, seed col- lecting (to be submitted August i), working plan modifications, converting factors, free use, timber sale advertising, trespass, timber reconnaissance, new sales proposed, protection of timber resources, stock excluded areas, brush burning and proposed in- vestigative projects. Under each caption there are sub-heads, which suggest the in- formation necessary and desired. Practically all of the informa- tion wanted is data which are called for from Supervisors during the course of the year. The annual plan, therefore, accomplishes two things. It brings together all the information which super- visors must submit to the District Forester during the year, and it gives the Supervisor a chance to bring to the attention of the District Forester in a systematic way certain facts about his For- est, which cannot be discussed in any other place. This plan should be brief, and only subjects in which the Supervisor desires to bring changes or new policies to the attention of his superiors, should be discussed. The annual plan, in other words, is to be a practical business measure. This will also give a chance to remedy any defects in the periodic plan. In other words, if the periodic plan contains anything which is not practical and does not work, the Supervisor here has a chance to remedy it. 3. Maps. These are of great importance, as everyone will 154 Forestry Quarterly. admit. Here should be included type, stand, reproduction, plant- ing and timber sale maps. They should be prepared on a base map showing topography. The type map may show the aliena- tions. Others need not. All m.aps (or part of them only) may show logging units, inaccessible areas, protection forests and such other necessary data. In addition to these maps, topographic township plats, section sheets (reconnaissance), and logging unit descriptions will be maintained. These descriptions will be detailed and comprise all forest description data necessary for timber sale work. They will be the most detailed descriptions of the whole plan. The description of each logging unit should be a separate report. 4. Appendix. This will comprise, in separate folders in the files, information of permanent value. From year to year this information should be built up. It need not necessarily be com- piled, although all information on a certain subject should be placed in the same folder for compilation in the future. Data on silvics, lumbering, costs, scaling, marking, brush disposal, plant- ing, insect control, etc., etc., will be included here. 5. The preliminary plan. In the past, preliminary plans have been considered by some as mere inventories of resources. They should be more than this, however. This inventory under the plan here proposed will come under the card records and the ap- pendix file. The preliminary plan on the other hand will be a true plan of management for the forest. The fundamental basis for the preliminary plan is that the for- est is the largest unit for the plan, that the plan should not be for over 10 years, that it shall be made by a specialist, and that it should be revised annually. It has been found that, unless the forest is taken as the largest unit for a plan, so many difficulties arise that the plan is not prac- tical. Separate plans may, however, be made for parts of a forest if they are distinct units, which should be handled sepa- rately. The continuity of the stand of timber generally deter- mines this. Ordinarily, plans have covered a full rotation in a general way and a period of from 10 to 20 years very definitely ; that is, plans have been attempted for a complete rotation. The writer con- siders plans for policies, cuttings, etc., for a period of more than Preparing Working Plans. 155 10 years as mere paper work at the present stage of the develop- ment of the National Forests. It is thought, therefore, that to be of practical value they should be confined to a ten y«ar period or even less. It must be conceded that to be of the greatest value, plans must represent the best thought of the District. Therefore, to secure uniformity and to obviate the need of rew^riting much of the ma- terial submitted to the District Forester, a special corps of forest plans men must be organized. These men must have knowledge of timber and logging requirements, and at the same time be able to present the data collected in a clear concise and systematic way. In short, they must be practical foresters of a high type. It is not proposed that these men make the plans independent of the Supervisor. On the contrary, the plan should be drafted in closest co-operation with him. The Supervisor must be consulted on all points of policy, for there should be joint responsibility. Field assistance, necessary to complete the plan, should be rendered by him. Annual re- vision of the plan is provided for in the Supervisor's annual plan. At the end of the period which the plan covers a new one should be made by a specialist. The preliminary plan should cover approximately the following points: Introduction (very brief); Markets; Past Lumbering (very brief) ; Forest types (very brief). In the introduction the objects of the management should be discussed. This is very important. A discussion, for each im- portant type, of the kind of product desired, with special refer- ence to present methods of cutting, should be given here. Markets must also be taken into consideration. Clear-cut conclusions as to how to attain the ends desired must be drawn. The silvicultural methods (by type and logging unit) are to be discussed, covering the objects and methods of cutting and pro- tection after lumbering. The plan need not go into details in reference to logging units on which no cutting is probable in the 10 year period of the plan. The timber sale policy is one of the main points in the plan. Here should be discussed the proposed timber sale business, such as restriction, development, encouragement, location and regula- tion of sales. It really shows what business is to be transacted and the business policy of the forest. I $6 Forestry Qiiarterly, The free use policy (very important) should be discussed as shown under timber sale policy. There should be a discussion of yield based on timber sale and free use policy (above) and the fixing of the annual or periodic yield. According to this, yield regulation must be subordinated to silvicultural requirements and to market. It is clearly valueless to impose a limitation of cut, which is impractical, because of the necessity of a large annual cut to justify commercial logging. At least until the over-mature timber is removed the policy of a sus- tained annual yield need not be applied. Even a periodic sus- tained yield need not be attempted until it is clearly and posi- tively necessary for reasons of public policy. In other words, it is unnecessary to pursue an academic ideal of sustained annual yield. In the discussion of the yield problem, however, it will be ad- visable to check the practical requirements with an academic estimate of the yield capacity by formula, volume, area or such other theoretical checks as can be applied. This will necessitate a short discussion on rotation, which will be based on the class of material which it is desired to produce and not upon financial or volume returns'. Distribution of yield should also be discussed, i. e., areas cor- responding to logging units which should be cut in order of im- portance. The discussion, while it should be practical, should consider these areas both from a silvicultural and market stand- point. The plan will really constitute in itself a concession that policy and silviculture must overtop regulation. It is not intended that the outline for a preliminary plan should be rigidly followed. It is given merely as a suggestion of the kind of material to be included in the plan. The writer wishes to convey the idea that preliminary plans- should be practical and for short periods; that they should be as brief as possible yet omit no essential details; that they should be based on actual local conditions; that they should contain more policy and less theoretical regulation of yield than in the past, and that although the conclusions should be based on silvical facts, these facts need only be referred to and need not be a part of the plan. 6. Final Plans. It is believed that the time is not yet ripe for final plans. As far as the writer is aware, no practical prelimin- Preparing Working Plans. 157 ary plan for a national forest has yet been made. When one of these has proved practical after several years use, it is time enough to talk of final plans. The system of annual and preliminary plans and other data, described above, has not been put into actual practice. If plans on this basis are attempted a great many stumbling blocks will probably be encountered and during the progress of the work numerous changes may be necessary. It is believed by the writer, however, that the general scheme is sound, and that by following it a practical form of forest management may be established for the National Forests. The writer intends this article to stimulate discussion on this very interesting, yet most difficult of the problems which the Fed- eral Forest Service has to solve. STEM ANALYSES. By John Bentlky, Jr. From the experience gained in instructing several classes in the subject of volume growth in individual trees, it is apparent that the method described in the text books in use in this country is difficult of comprehension by the average student of forest mensuration. As a general rule, the problems of height growth and diameter growth are handled by the majority of students quite readily, but they frequently have difficulty in mastering the subject of volume growth as exemplified in "stem analyses." In searching for the cause of this trouble, it appears that much of it arises from the form in which stem analyses are usually re- corded in this country; and the object of this discussion is to recommend a more logical tabulation of the data usually included on a stem analysis blank. It will be remembered that the blanks provided for stem analysis by the Forest Service (Form 334, "Tree Measurements") include a page in which the measurements on each cross-section of the tree are recorded in columns numbered i, 2, 3, 4, 5, etc., (which represent decades), the values showing the "distance on average radius from heart to each tenth ring." If, as is gener- ally the case, there is not an even multiple of ten annual rings on the section, the measurement of the odd years is recorded under column i, (since the measurements begin with the inner- most period and proceed outward), and from that point on, the difference between the values in any two adjacent columns repre- sents a decade's growth. So far, so good ; but when the measure- ments for the second and subsequent cross-cuts are recorded, the measurements in each case are tabulated beginning in column i again; and since there is almost always at least ten years differ- ence in the total ages of successive cross-cuts, and sometimes twenty, or more, the measurement for the last, or current decade, falls, not in the column for the corresponding decade on the pre- vious cross-cut, but in a column to the left. Glancing down the numbered columns, then, we find a series of measurements each one of which represents a diflferent decade in the tree's life- Stem Atialyses. icg history. An example of this method of tabulation is shown in Professor Graves' well known book on "Forest Mensuration," page 264, where the age of the tree at cross-section number i (stump) was 60 years, and the last measured radius was conse- quently recorded in column 6. The age of the second cross-cut was 50 years, and the last measured radius was recorded in col- umn 5, etc. When the volumes of the several sections are computed for different decades there is a very large chance that the wrong pairs of values for cross-sectional dimensions will be selected, because, instead of being arranged one under the other in the same column, the dimensions of the cross-cuts belonging to any particular age of the tree are found in different columns, and they must be selected by counting backward from the last recorded measurement. This is one point at which the average student has difficulty, and one which can be obviated entirely by the use of a more logical method of tabulating the measurements. A second point at which there is usually some difficulty is in the doubling of the measurements given for radii, so as to obtain the corresponding diameters. The form already referred to reads: "Distance on average radius from heart to each loth ring — inches" and the student not infrequently forgets to double the value recorded for the radius, in order to obtain the diameter. While this may seem like a trivial point, it is, nevertheless, one which often leads to slight errors in doubling, or neglecting to double at all; and when the use of a scale reading 2 : i would obviate the necessity of recording radii, and permit the recording of diameters directly, it seems wise to take simple precautions and eliminate the chances of errors, by recording diameters in- stead of radii. Stem analysis rules as now made by instrument- makers, usually make readings of this kind easy by supplying two scales', — one graduated to inches and tenths, for measuring di- ameters, and the other for measuring radii graduated to half- inches and twentieths, but reading as doubled inches and tenths, so that radii may be read directly as diameters. The stem analysis blank would therefore read, preferably, over the columns pro- vided for the measurements: "Average diameter of section, by decades," instead of "Distance on average radius from heart to each loth ring." A third point, — and one which is a source of frequent errors i6o Forestry Quarterly. in computing the volume of the tree at different periods — is the somewhat laborious and involved method of determining the dimensions of the tops (above the last cross-cut), in preceding decades. These tops are generally regarded as cones (see Graves' "Mensuration," page 292), and their volumes computed as such. The difficulty arises in obtaining the heights of the sev- eral cones as they appeared further and further within the top, or down the stem, with each preceding decade. The method de- scribed by Professor Graves, namely, to take a distance propor- tional to the number of years required to grow the distance be- tween the two sections in question, thus assuming a regular rate of growth for the period, is quite accurate, but it is likely to confuse the student, and has been the cause of more errors in com- putation than any other one factor, according to my observation.* In German text books the method described for obtaining the volumes of the tree in preceding decades frequently disregards these small cones, or tips, because the sections into which the tree is divided for analysis are short, — rarely more than 2 meters. The volumes are therefore relatively insignificant. In this coun- try, however, where we have to compute stem analyses from trees where a top of 15, 20, or even 30 feet is left, it becomes necessary to include these tops, and their dimensions at different periods, otherwise the calculated volumes would be inaccurate to such a degree that they would be of no scientific value. Some way must be devised, therefore, which will yield accurate results, and at the same time will be readily understood and applied by the student. In the hope of simplifying the work of making and recording stem analyses, and eliminating some of the obvious causes for mistakes in the calculations, the following suggestions are made. Nothing new or original is claimed for these suggestions ; on the contrary, they have all been prompted by a perusal of the stand- ard German text books. They are presented here simply for the purpose of showing how the work may be made more logical, and * It has even led to an error in the very example chosen to illustrate the niethod (page 291 in "Forest Mensuration"), where, in the computations for the tree as it was 30 years old, the length ascribed to the tip is 475 feet. Since the tip at that age comprised 10/16 of the length of the section (10 feet) it should evidently be 6.25 feet, and not 4.75 feet, as printed. Stoii Analyses. l6i at the same time more comprehensible to the mind of the average student of forest mensuration. First, as to the methods of tabulating the measurements taken in the field. Figure i (page 162) shows a revised form filled in with data from a White Pine, in which the usual measurements are recorded, together with a few additional ones which will ren- der the computations in the office less liable to error. For con- venience, the spaces in which the measurements are recorded are both named and lettered, to correspond with the following list; and in the discussion which follows the several columns will be referred to by letter.

A timber estimate, at best, is an approximation of the actual amount of timber on the ground. The very term "estimate" in- dicates this. The accuracy of the approximation will depend on the accuracy and the intensiveness of the estimate, though the true error involved can never be determined because the actual volume can never be determined with absolute accuracy. The sources of error in timber estimating may be divided into three classes, as follows : 1. Errors inherent in the method of estimating used. It stands to reason that if the principles on which any system of timber cruising is based are fallacious', the results obtained will be in- accurate, no matter how carefully the work is done. 2. Errors in the application of the system. The system of estimating used may be sound in principle, yet if it is not ap- plied accurately, the results will not be correct. Personal mis- takes, carelessness and negligence, as well as errors due to the use of unreliable volume tables, come under this heading. 3. Errors involved in making an estimate on only a small part of the area. Even if the system used is correct and it is ap- plied carefully, there may still be errors in the estimate due to the fact that the cruise does not cover an extensive enough pro- portion of the area to which it is- applied and the proportion cov- ered is not representative of the rest of the area. This paper will confine itself largely to the last mentioned source of error. It is hardly necessary to enter here into a detailed discussion of the different methods of cruising timber. With the exception of a very few systems of ocular estimating, most of them are based on a per cent, estimate. That is to say, only a given per cent, of the area is measured and the content of the entire stand is obtained by proportion. Other things being equal, the higher the per cent, of the area actually measured, the more accurate, of course, is the cruise. Still it is only in very rare cases' that a 100 per cent, estimate is practicable. The usual cruise covers either 5 or 10 per cent, of the area. i68 Forestry Quarterly. The accuracy of any given per cent, cruise will depend : 1. On the uniformity of the distribution of the timber. The more evenly distributed the timber, the more accurate is the estimate, because the sample areas measured are then most likely to be representative of the entire forest. 2. On the size of the area to which it is applied. While a 5 per cent, estimate may give very inaccurate results when ap- plied to a single "forty," it may give quite satisfactory results when applied to an entire section, because the errors in the esti- mate of the individual forties are then compensating, the cruise on one being too high and on another too low. Assuming that a given system of estimating is correct and that its application is faultless, the question arises: How small a per cent, of area is it safe to estimate to obtain a satisfactory cruise of a given stand, and for a given per cent, cruise how small an area can it be safely applied to? Some light on this question has been thrown by work done in California by the Forest Service during the past year. Here a complete lOO per cent, estimate was made on 2200 acres of forest. By comparing a 5 per cent, and a 10 per cent, estimate on the same area with the 100 per cent, cruise, the errors in- volved can be determined and studied. The area of 2,200 acres on which the test was made consists of two parts ; one, an area of 640 acres on the Plumas National Forest, and the second, an area of 1,560 acres within the Yosemite National Park. On the Plumas, the work was done primarily for the purpose of determining the relative accuracy of a 5 per cent, and a 10 per cent, cruise. In the Yosemite, the test was necessary for administrative purposes. The two areas will be discussed separately. The Plumas Area. The area selected contains 640 acres and is of irregular shape, covering parts of four sections. The stand of timber averaged about 28,000 board feet per acre, and the forest was mainly of the mixed conifer type in which yellow pine and Douglas fir each averaged about one-third of the stand, sugar pine about one- sixth, incense cedar about 5 per cent., the remainder being white fir. Although the topography was not as rough as' is typical on most of the Sierra forests, several exposures were represented. The work consisted of: Errors in Estimating Timber. 169 1. Measuring the breast high diameter of every tree on the area more than 12 inches in diameter. 2. Measuring the heights of a sufficient number ,of trees for reliable height curves. 3. Running valuation survey strips, one chain wide, at inter- vals of 10 chains. The diameters of the trees were measured with Biltmore sticks, checked up frequently with diameter tapes. In order to avoid measuring the same trees twice, the lines were run in strips and the outside strip on every trip was marked with white chalk or crayon. There were 18,072 trees on the area, 12 inches and over in diameter, an average of 28.2 trees per acre. Only compara- tively few trees were more than 42 inches in diameter. It was, of course, impracticable to measure the height of every tree on the area with a hypsometer. A sufficient number of heights of the different species was therefore taken to furnish the data for a reliable curve. Height measurements were taken on over 1,000 trees well scattered over the entire area and repre- sentative of all the types and situations found on the area. These were then curved and a local volume table was' constructed for each species from the regular District volume tables. After all the trees on the area were measured land a sufficient number of heights were obtained, the work of estimating the timber was begun. The total tract of 640 acres was divided into five lots', as below. It would have been more satisfactory to have divided the area into 40 acre tracts, and estimate and compute each forty sep- arately. This, however, was impracticable for various reasons. Strip lines were run 10 chains apart twice through a forty. By taking only one of these strips through each forty, a 5 per cent estimate of the timber was obtained. By taking the other strip through each forty, a second 5 per cent, estimate was ob- tained. By combining these two strips', one gets a 10 per cent, estimate. In estimating the timber, the personal equation of the cruiser was eliminated as far as possible. Most of the di- ameters were measured, the hypsometer was frequently used, and the distance from the compass line to the edge of the strip was fre- quently paced or measured in order to get the proper width. The crew consisted of the most experienced reconnaissance men in the District. 170 Forestry Quarterly. Table I shows the results of the estimate. The percentages of error have been worked out for each species, for each lot and for the totals. Table i. PLUMAS AREA. Comparison of Bstimates. 5% Estimate. First. 5% Estimate. Second. 10% Estimate.

It will be noticed, for example, that in many instances the 5 per cent, estimate gave better results than the 10 per cent, estimate. This is to be expected since the 10 per cent, estimate is the total of the two 5 per cent, strips, and the error is half way between the errors involved in the 5 per cent, esti- mates. It also shows that a particular cruise line often happens to pass through a stand more typical of the entire area than is represented by the average of the two strips. On the other hand, the maximum error, as might be expected, is very much greater in the 5 per cent, than in the 10 per cent, cruise. Thus, while the greatest error by the 10 per cent, method, considering only the totals, is minus 12 per cent, in Lot C, the greatest error in the 5 per cent, estimate is minus 31 per cent in Lot A. The totals for individual lots show greater error than the total for the entire section, the greater errors' being respectively minus 31 per cent, and minus 10 per cent, in the 5 per cent, cruise, and minus 12 per cent, and minus 6 per cent, in the 10 per cent, cruise. The individual species, especially on the separate lots, show the greatest error, which in one case amounts to over 100 per cent. When the totals for the entire section are considered, the great- est per cent, of error is plus 40 for sugar pine in the 5 per cent, estimate and minus 30 for incense cedar in the 10 per cent, cruise. Ths Yosemite Are;a. The check-cruise on the Yosemite tract covered an area of 1,560 acres, located at an elevation varying from about 4,000 to 6,800 feet. The forest consists of a fine stand of timber averag- ing over 46,000 feet per acre. The species in mixtures are yel- low pine 37%, sugar pine 32%, fir 19% and cedar 12%. The topography is quite level and all exposures are represented. The usual types are yellow pine and sugar pine. There were 35,529 trees, 12 inches and over in diameter, on the area measured, or an average of 22.8 trees per acre. Of this number, 491 trees or an average of .3 trees per acre were more than 60 inches in diameter. The original estimate was made by a crew consisting of nine men, four of whom had had previous reconnaissance exper- 172 Forestry Quarterly. ience. Before the actual work of estimating was begun hypso- meter height measurements were taken on about 4,ocx) standing trees on the tract to be cruised. From these data three height curves were constructed for each species, showing the average height of trees of each diameter class on site I, II and III. Cruise strips one chain wide were then run 10 chains apart, giv- ing the 10 per cent, estimate of the area. All trees on the strip more than 12 inches in diameter were tallied by species in 2 inch diameter classes. Trees 32 inches in diameter or less were esti- mated, but the eye was checked several times a day by taking actual measurements. Trees more than ;^2 inches in diameter and less than 60 inches were measured by means of a Biltmore stick. Trees more than 60 inches in diameter were measured by means of a diameter tape. Every strip on each "forty" was classified by the cruiser into its proper height class. The re- sult of this cruise was two 5 per cent, estimates which, when combined, gave a 10 per cent, estimate. The 100 per. cent, estimate was made by a four-men party as follows : One man ran compass and lightly blazed the trees along his course; a second man ran through the center of the strip tallying the trees and watching the cruisers to see that no trees were omitted. The other two men measured or estimated all the trees on the tract and called them out to the tallyman. A strip 2j chains in width was taken on each trip, which necessitated 32 trips for each section. The height class of each species was determined from the height curves as in the original estimate, the hypsometer being frequently used to check the eye.

To bring them out more clearly the maxima errors have been picked out and listed below, beginning with those occurring on the largest area. Section 16, covering a total of 640 acres, has been omitted from this tabulation because it is a very erratic section and a check on the ground showed that the original estimate on it was very poorly made, being quite unreliable.

Column six shows the difference between the greatest error by the 5 per cent, and the 10 per cent, estimate, when the total cruise of the tract is taken 1/4 Forestry Quarterly. under consideration, while column seven shows the same for the individual species in each tract. The last two columns in the table are the true measure of the relative accuracy of the 5 per cent, and the 10 per cent, estimates. It will be seen that when the entire area of 1560 acres is con- sidered the 10 per cent, estimate cuts down the maximum error by 5 or 6 per cent., but when individual "forties" are considered the difference in the greatest error between the 5 per cent and the 10 per cent, cruise amounts to 33 per cent., if only the total estimate is considered, and to 68 per cent., if the individual species' are taken into consideration. The table brings out very clearly the danger of giving out de- tailed estimates by small areas when only a comparatively small per cent, of the area has been estimated. It shows, for example, that when a 5 per cent, cruise is made and the error is as high as 71 per cent, on an individual "forty" it drops to a maximum of only II per cent, on 1,560 acres. In a 10 per cent, cruise the greatest error drops from 38 per cent, to 5 per cent. When in- dividual species are taken into consideration the increase in ac- curacy by lumping the estimates is still more apparent. The inaccuracy of the estimate on individual "forties" in the Yosemite tract was no doubt increased by the occurrence of a few very large sugar pines from 70 to over 100 inches in diameter. It stands to reason that where these large trees occur sparingly on a "forty" and the cruise strip happens to strike one or more of them the estimate will be too high; if it misses them the estimate will be too low. In either case the error will be large unless there is a sufficient number of these big trees to allow of a uniform distribution. It should be borne in mind that the object of the discussion is to show the relative accuracy of a 5 per cent, and a 10 per cent, cruise, and that we are therefore not concerned with the actual errors made. It must be remembered also that Table 3 gives the greatest errors and is no indication of the actual ac- curacy obtained by the original cruise. Since most of the government timber on the National Forests is sold by actual scale, and not by estimate, it would seem that a very careful cruise is not required. However, since the stump- age price charged will depend to some extent on the amount of Errors in Bstimating Timber. 175 timber on the area for sale, an accurate cruise becomes of con- siderable importance. To discover how serious a change in the stumpage price would be made by an error in estimating, two bodies of timber, one in the Yosemite and the other on the Plumas, each containing approximately 300,000,000 feet, were appraised and then reappraised after changing the timber estimate by 5 and then by 10 per cent. It was discovered that an error of 5 per cent, in the estimate would make a difference of approximately 8 cents per M feet in the case of the Yosemite timber, where the appraised stumpage was $3.15 per M. and about 7 cents in the case of the Plumas, where the appraised value was $2.37. An error of 10 per cent, in the estimate will make a differenc of about 20 cents per M. feet in either case. Figuring an average cut of 20,000 board feet per acre, this error means a loss per acre of $1.40 if the error is 5 per cent, and $4.00 if the error is 10 per cent., either to the Government, if the cruise is an under- estimate, or to the operator if the cruise is' an overestimate. This expressed in terms of per cent, of stumpage price means that an error of 5 per cent, in the estimate will affect the price by 2^ per cent, and an error of 10 per cent, will affect it by 7.2 per cent. Cruisers estimating timber for private purchasers or sellers as a rule aim to get the estimate within 10 per cent. In other words, a cruiser's work is passable if he comes within 10 per cent, of the actual timber on the tract. Providing his cruising is uniform this would mean an error of 10 per cent, in the value of the timber on the area. It appears advisable, there- fore, to spend a little more money in order to get a more ac- curate cruise. The following deductions may be safely made from the above discussion and tables : Assuming that the method of estimating is correct and it is carefully applied, a 5 per cent, estimate will give fairly satisfac- tory results for an area not less than about 1,500 acres. A 10 per cent, estimate may give fairly satisfactory results for an area as small as a section in extent, but for smaller areas than that even a 10 per cent, cruise is not very reliable. Where more detailed estimates are desired more intensive cruises are essen- tial. The practice of making a 5 per cent, or even a 10 per cent, cruise and then giving out the estimate by 40 acre units is 176 Forestry Quarterly. inaccurate and misleading and should be discontinued, especially so since such a detailed estimate seldom serves a useful purpose. The greater accuracy obtained by a 10 per cent, cruise over a 5 per cent, cruise is entirely out of proportion to the difference in the costs, and it appears to be good business therefore to make the more intensive cruise, especially where detailed figures are desired. EXPLOITATION OF CROSSTIES IN NORTHERN NEW MEXICO* By Ci' line of work. The working plan for each project should be revised each winter, indicating all changes in the previous plan with respect to time and extent of operations, location of plots, and other details which may change from year to year. To guard against overlooking details at the proper time, a summarized schedule of operations should be made up for each project. In addition, a schedule showing the work planned for all projects at different times through the year is recommended. The director of a station may frequently be called upon to make minor modifications in his plans. Perhaps the work out- lined for a certain period is found too heavy, and then he must decide what work can be deferred and when it can be done to the best advantage. Climatic conditions or other circumstances may arise which render it advisable to defer or omit entirely certain operations, or to add others not provided for in the plan. Ob- viously, the number of changes which become necessary in the execution of the plan is determined to a great extent by the amount of forethought exercised by the writer of the plan and his knowledge of the conditions under which it is to be carried out. The preceding statements apply to experiment stations under present conditions. As scientific standards rise, more responsi- bility will be placed upon individual investigators, with a corre- sponding decrease in supervision. Personnel. The general qualifications required of the scien- tific staff of an experiment station are much the same as for other forest officers. Until recently it seems to have been taken for granted that a Forest Assistant who showed any scientific inclination, even though he failed generally in the usual work on a National Forest, was qualified for scientific work. For- tunately, this impression is being corrected. Men of poor ad- ministrative ability or unfortunate personality may be well fitted for certain kinds of scientific work, but the man who fails in National Forest work through lack of character, industry or mental capacity will also fail at an experiment station. An un- derstanding of National Forest work and the aims and problems of the Service is of great value to every man engaged in scientific work, and at least one year's service on a National Forest should 2i8 Forestry Quarterly. be required of a Forest Assistant before he can be permanently assigned to an experiment station. The number and training of men on the scientific staff will obviously be determined by the amount and character of work carried on. The director and one assistant, who will be called upon to take charge in the absence of the director, must have at least ordinary administrative ability. In addition, if the amount of work warrants, one or more purely technical men may be employed. For detailed work involving comparatively little judgment and responsibility, young men of incomplete scientific training can be used to good advantage. Forestry students are as a rule exceedingly ambitious and energetic, and on work more or less routine in character, requiring physical activity rather than scientific knowledge, they are often more efficient than older men of higher technical training. But the mistake of placing students in positions requiring training and experience should be avoided. Two technical men assisted by one or two students generally constitute a more effective force than one technical man assisted by three or four students. A common mistake of technical men is to devote too much of their time to work which can be performed more economically by a common laborer. Often such work is necessary as, for in- stance, when the amount of work does not warrant employing a laborer; but it is clearly poor economy for a $1,200 technical man to spend much of his time building fences, digging ditches or packing burros, when the same work can be done better by a laborer employed at $2.50 per day. The above does not apply to students who generally receive no more pay than a laborer, and who can often be employed temporarily at manual labor when not needed on scientific work. The greatest need of the scientific branch of the Forest Ser- vice is for higher scientific standards in the personnel. For- esters must be developed within the profession, and since forestry is new in this country few of our scientific men rank with the leaders in the older scientific professions. To remedy the situa- tion, men of high training and ability are needed who will de- vote their lives to forest research. Forest experiment stations should in years to come represent the highest scientific talent in the Forest Service. The personnel should be made up of specialists. The director of a station Forest Experiment Station. 219 should be a recognized authority who has perhaps spent his life time in the study of forest problems. Such men should rank with the highest officers in the administrative branch of the Forest Service. There is, however, little danger that the director of a station will not receive due recognition. The danger is with the subordinate officers. Every man wants to be able to see something ahead, and if he can not he is going to look for a new field. At present, a position as assistant at a forest experiment station carries with it no scientific recognition and gives little promise of leading to anything higher. Occasionally one of these men will be called upon to fill a vacancy as director of a station, but such promotions will be rare. The best solution of this problem is to make the subordinate positions carry with them responsibility, remuneration and dig- nity commensurate with the abilities of high class scientific men. At agricultural experiment stations a specialist is in charge of each line of work and he is designated by a title such as agro- nomist, horticulturist or botanist, which gives him recognition in the scientific world. A similar system could be put into effect at forest experiment stations, although there are objections to adopting a number of highly technical titles. The following scheme proposed by District Forester Ringland seems to meet the requirements. The officer in charge of the station would be designated "Director" and the assistants in charge of the various lines of work "Assistant Directors." There would be as many assistant directors as there are men in charge of special lines of work, and all would be of equal rank. The following tentative division of work and designations of officers are suggested: Class of Work. Designation. 1. General supervision.

Ordinarily only one or two Assistant Directors will be em- ployed at one station for the present, but a growing volume of work and need for greater specialization will in time necessi- tate an increase in the force. The rank of Assistant Director should be reserved for men of proven ability, and should require in addition to other qualifications at least two years' previous service as Forest Assistant on a National Forest, or equivalent training. Ordinarily a period of apprenticeship at an experiment station should be required, although it would not be advisable to make this an inflexible rule. Higher requirements would be desirable, but are not practicable at present for the reason that qualified men are not available. As the scientific standard rises, the requirements should be greatly increased, until after per- haps ten or fifteen years only seasoned men of high scientific training and ability are eligible to one of the higher positions at an experiment station. Scope of Scientific Work. The primary purpose of our ex- periment stations and, in fact, of all scientific investigations in the Forest Service is to furnish scientific data needed in the management of National Forests. To accomplish this, the sta- tion must be actively in touch with the work on National For- ests. Every investigator should be given an opportunity to see the conclusions of his studies put into practice. The specialist in forest management at the experiment station should take an active interest in marking, cutting, brush disposal, etc., and his services should be utilized in the inspection of timber sales. When extensive planting operations are undertaken the specialist in charge of reforestation at the experiment station should be consulted in regard to technical matters, such as the selection of areas, methods, species, etc. He should make inspections of the work from time to time with a view toward lending helpful sug- gestions and solving problems which can not be solved by the administrative force. Similarly, the services of officers in charge of insect, grazing and botanical investigations should be utilized within their respective fields. Obviously such a system of co-operation can not be fully real- ized until specialists in the various lines become available. More- over, experiment station men should not be required to give an undue amount of time to District inspection at the expense of individual research. They should act in advisory capacity in co- Forest Experiment Station. 221 operation with administrative officers and should not ordinarily be burdened with administrative responsibility. In special cases, however, it may be desirable for such officers to take entire charge of a project in order to familiarize themselves with the conditions met in actual practice. What promises to be a new field of activity for the experi- ment station is developing out of the demand of the public for technical advice on forestry. Already a considerable number of requests for information in regard to tree planting are being received from western states outside of the field of the Wash- ington Office of State Co-operation. If these requests increase materially in number, as they undoubtedly will, some provision must be made for handling them. In some states, a large por- tion of this work can be referred to the agricultural experiment station, but in states' which do not maintain a Department of Forestry, it will fall upon the Forest Service. It has been the experience in District 3 that many of the requests for informa- tion, particularly in regard to tree planting, are difficult to handle because they come from agricultural sections in the lower alti- tudes where conditions are entirely different from those on the National Forests. If the Service continues the policy of fur- nishing advice to private owners it must make the investigations necessary to give reliable information. These investigations will logically devolve upon the experiment station, but routine cor- respondence and the execution of co-operative agreements should as far as possible be handled by administrative officers. The experiment station has an unusual opportunity for edu- cational influence. The public is rapidly awakenmg to the im- portance of forestry and is looking for evidences of the work of the Forest Service. An experiment station, if at all accessible, is visited by a great number of people annually. Many are at- tracted by mere curiosity, but others show a genuine interest in the work. Not a few of these visitors are persons of scientific prominence. The experiment station is thus called upon to up- hold the scientific prestige of the Forest Service. A well con- ducted nursery and a few successful plantations are a revelation to the average layman. Reforestation appeals to the public more than any other phase of forestry, and for this reason it is desir- able that the experiment station locate its nursery and some of its plantations where they can be conveniently reached by visitors. 222 Forestry Quarterly. Advantage should also be taken of the opportunity to explain the broader aspects of forestry. The object and possibilities of forest management through the practice of good silviculture, con- servative lumbering, fire protection and regulated grazing should be pointed out and demonstrated as far as possible. To this end, a model forest managed by the experiment station would serve an excellent purpose. Forest influences, especially if studies of this character are being carried on at the station, can be profitably discussed. The time which must be given to visitors by officers of the experiment station is a considerable item which should be considered in fixing the annual program of the station. THE PROBABLE ORIGIN OF THE FORESTS OF THE BLACK HILLS OF SOUTH DAKOTA. By p. L. Buttrick. In 1896, the U. S. Department of Agriculture published a list of plants from the Black Hills Section of South Dakota.* It was compiled by Dr. P. A. Rydberg, mainly from his own col- lections. In the introduction he speaks briefly of the probable manner in which the various species reached the region. Perhaps- an amplification of the subject as it applies to forest trees may be of sufficient interest to foresters to warrant publi- cation. Most of the conclusions expressed here were reached by the writer before seeing Dr. Rydberg's Bulletin. The Black Hills in southwest South Dakota and eastern Wyo- ming rise to a height of nearly 5,000 feet above the surrounding plains', and cover an area about the size of the State of Connecti- cut. They present conditions in every way different from the treeless plains and Badland surrounding them. In contrast the Hills are (or were) heavily timbered. They form what is essentially an island — an island in the midst of the land. Like other islands they have received their fauna and flora from neighboring but larger lands, and, after receiving it, have modified it to suit their own peculiar insular conditions. Islands receive such plants and animals as are, in some man- ner able to cross the barriers to them. Wind, water, birds and insects are among the agents supplying islands with plant life. Doubtless these have done their part in the colonization of the Black Hills. However, migrations along well defined lines are responsible for the presence of most, possibly all the tree species of the Hills. Western Yellow pine (Pinus ponderosa) is the most important tree, constituting at least 90 per cent, of the forest. The other pines, Lodgepole (Pinus murrayana) and Limber pine (Pinus *Contributions from U. S. National Herbarium, Vol. Ill, No. 8, 1896. Division of Botany, U. S. Department of Agriculture. 224 Forestry Quarterly. flexilis), are found as' scattered trees or in small groups, so rare that they long escaped notice. White spruce (Picea canadensis) occurs in a few solid bodies on the slopes of the highest hills. Elsewhere it is largely con- fined to canyon bottoms and steep north slopes in mixture with other species. Red cedar (Juniperus sp.j is scattered about the foothills, chiefly in the Wyoming section. The form in the Hills seems intermediate between the eastern and the western Red cedar. There are a large number of hardwoods, all of minor impor- tance. The list comprises such species as : elm (Ulmus Ameri- cana), hackberry (Celtis occidentalis), Bur oak (Qiierciis macro- carpa), boxelder (Acer negundo), Paper birch (Betula papyri- fera), Red ash (Fraxinus pennsylvanica) , Trembling aspen (Populus tremuloides), cottonwood (Populus deltoides), and others'. There are several other species but they are too insig- nificant to mention. Bur oak is the only hardwood reaching any size. Occasionally in stream bottoms in the foothills it becomes large enough for railroad ties. All the hardwoods, with the exception of aspen and paper birch, and in a few sections Bur oak, are confined to the stream bottoms or the vicinity of water. They are more numerous and better developed in the foothills and at lower elevations. Aspen and birch often form temporary types after fire or clear- ings'. It will be seen that the species in the Black Hills fall into four groups according to the forest regions where they are most com- mon. These are : Rocky Mountain species ; Northern Forest species ; Eastern Forest species ; and Transcontinental species. Most of the last group might be classed also in the third. The pines belong in the first group. The spruce and Paper birch in the second. The other hardwoods in the third. Trans- continental trees such as aspen and boxelder are undoubtedly of eastern origin. How have these representatives of different forest regions found their way to this prairie island — the Black Hills? There seem to have been three migration lines. From the north, the east and the west. At one time, the climate of the west was much more humid Probable Origin of the Black Hills Forests. 225 than now, and much of the treeless area north and west of the Black Hills was doubtless forest covered. The Rocky Mountain forest extended more or less completely across that strip of relatively high land called the Wyoming Badlands, which stretches from the Bighorn Mountains in Wyoming to the Black Hills. Even to-day a few stunted yellow pines are found scattered across this area. Undoubtedly across this forest isthmus came all the pines of the Hills. From the north a tongue of forest may have stretched south- ward along the isolated buttes and ridges lying in what is now eastern Montana and western Dakota. If so, this slender strip of forest is responsible for the presence in the Hills of the white spruce and the paper birch. It may be, however, that these species owe their place to the accidental agencies of birds or winds, as is apparently thought by Dr. Rydberg to be the case with the spruce. From the eastern forest long tongues extend westward across the plains following the river banks and smaller water courses almost to the foot of the Rockies. It is probable that most of the hardwoods of the Hills reached there by this "river route," ascending the Missouri and then the Cheyenne and its tributaries which enter the Hills'. The transcontinental trees such as aspen and hackberry prob- ably came up the rivers from the east in the course of their journey across the continent. The Red cedar which follows the uplands may have come from the east or the west or both. It is a law of island colonization, that of the various forms which reach an island, some are rejected as unfit to cope with the conditions of their new environment, and others are modi- fied to conform to it. Perhaps still others well suited to the insular conditions never reach them. These are well illustrated in the Black Hills. Lodgepole and Limber pines have not found suitable conditions, and have been reduced to a subordinate position. In time they will probably disappear from the Hills. It is' possible that other Rocky Moun- tain species crossed the forest isthmus only to be unable to get a foothold or to be later driven back by the unfavorable conditions they encountered in the Hills. The trees from the northern forest, which of all the species have probably been longest in the Hills, have been more or less 226 Forestry Quarterly. modified by their environment and isolation. The specific status of both the spruce and the birch is in doubt, some authorities make distinct species of both. The species from the east have, in most cases, been modified both botanically and silvically. In some cases this modification took place on the long journey across the plains, in others since the arrival in the Hills. The narrow-leaved cottonwood (Popu- lus acuminata) , a varient of the common cottonwood of the plains, is an example of the first. The various willows are ex- amples of the second. These after the cool moist canyons of the eastern Hills after their long prairie journey under such vastly different conditions, have after the well known habit of willows varied greatly. It is almost impossible to separate them into recognized species. Bur oak and American elm, being old and stable species, have not varied botanically, but were dwarfed by the long plains journey, and have only partly succeeded in regaining their size. Perhaps the relatively dry climate is a fac- tor in this. The cosmopolitan Yellow pine has not varied botanically in the Hills as it has in its further eastward journey in the sand hills of Nebraska, where it has developed into a sub-species (Pinus ponderosa var. scopulorum) as a result of its changed en- vironment. Nevertheless Black Hills Yellow pine is silvically quite distinct from that in the Rockies. If the supposition that a narrow strip of forest once connected the Black Hills' with the great northern forest of the continent is correct, it is probable that at one time other species of the northern forest occurred there. Eastern larch, Balsam fir and Jack pine or forms very closely resembling them, would likely have been represented. A climatic change or the competition of the Yellow pine could account for their disappearance. The path from the Rocky Mountains was closed by the ad- vancing aridity of the region, perhaps aided by forest fires. The migration from the east is still going on. Many hard- wood species, such as the backberry and the ash, have scarcely yet penetrated beyond the eastern foothills. Few of those which have, have as yet been able to adapt themselves to grow upon the uplands, Bur oak and aspen being those which have come closest to it. If natural conditions were not interfered with in time it might be that some of the eastern hardwoods would regain the Probable Origin of the Black Hills Forests. 227 capacity to grow abundantly on upland sites as they do in their old eastern homes. It is possible that there are other species from the three forest regions which are more or less suitable for the Black Hills, but which have never been able to reach them. It is probable that the forces of evolution will continue in the future as they have in the past to produce specialized forms for insular conditions and that the differentiation of the trees of the Black Hills into local varieties and species will continue, chiefly among the hardwoods. It is not impossible that further acces- sions will be made from the eastern hardwoods as they work their way further and further west. And those species now at the gate-way of the Hills will climb higher and higher into them. Whether these changes will be rapid enough to be perceptible to us remains to be seen. It is unlikely that any species will of itself usurp the place of the Yellow pine, which despite the ravages of fire and insects holds its own so well. For the purposes of the forester and the lumberman the development of the forests of the Black Hills is complete. THE SCOPE OF DENDROLOGY IN FOREST BOTANY. By H. DE Forest. Any new branch of science, in its earlier stages, is necessarily in a plastic condition. For some time its organization represents' little more than accumulations of more or less closely related facts. Exactly what scope and proportions the subject shall ulti- mately assume remains a matter of conjecture and discussion. Then, later, as experience and further investigation lead to clearer comprehension and greater definiteness of intention, these facts are classified and arranged in established categories, so that, while the subject even then is still not a body of unchangeable form, it nevertheless has taken on definite proportions and occu- pies a more or less fixed space. It is peculiarly necessary at the present stage of the develop- ment of forestry in this country that the concepts of several branches' of the general subject be subjected to critical analysis with a view to their occupying their proper places in the forestry system and so most effectively discharging their functions. It is only by such methods that real advances in the technique of any line of scientific work can be made. Furthermore, such critical investigation, in order to serve best its' object of establish- ing sound bases for technical training, must be divorced from any purpose of making an acceptable popular appeal, a purpose that rightfully prevails in the presentation to the public of many lines of forestry work, and remain based solely upon scientific principles, with the somewhat abused term scientific employed here in its implication of technical service of a utilitarian object. It is proposed to examine briefly the subject of dendrology. For the clearest understanding of its scope it will be desirable to consider first what relations it bears to the rest of the general subject of forest botany to which it belongs. Place of Dendrology in Forest Botany — Its Relation to Ecologi- cal Science. Forest botany, it is believed, consists of two distinct parts. One deals with tree species, with facts concerning the individual Scope of Dendrology in Forest Botany. 229 trees that go to make up the forest. This is non-ecological. The other deals with associations of such trees, with those dynamic, organic entities known as forests, and is ecological. The former of these two parts is dendrolog}% while the latter is silvics. Some- times the term silviculture, which originally was reserved for the art of establishing, developing, and reproducing forests, is used to denote also the science back of that art, that is to say as a synonym for silvics, just as, for example, the single term medi- cine is often used to denote either the science or the art. Den- drology will be handled in the main body of this short article. Here it is necessary for a complete understanding to treat briefly the subject of silvics. It appears to the writer that the natural subdivision and the arrangement best suited for presenting the materials to students lies in this already well recognized separa- tion into dendrology and silvics. In addition to this there must be remembered the powerful and all-important fact, that alone should bring about such a subdivision to-day, to wit that now all ecological investigation, in order to facilitate scientific de- velopment in the methods of attack upon the intricate problems involved, is placed in a category by itself under some one or more ecological sciences. Silvics covers, it is believed, all ecological investigations of forests. Ecological investigation of vegetation is to-day pur- sued by means of the two sister sciences known as plant-geogra- phy and plant-ecology. The former of these is also known inter- nationally as phytogeography, while the latter has the interna- tional term phytecology proposed. They cover the field of eco- logical science in botany. Exhaustive expositions of the terri- tories included within these respective subjects or of their present stage of advancement would be both out of place here and im- possible within limited space. Suffice it to say, by way of fur- nishing accurate indicators of their meanings rather than ex- haustive definitions, that plant-geography is essentially a regional study of vegetation and proceeds along three lines, the genetic, the floristic, and the ecological. The first considers the his- torical origin and development of the vegetation of a region and is largely geologic. The second interprets the present regional flora from the point of view of its origin, migration, etc. Its delimitations are largely topographic. The third puts the pres- ent regional vegetation in its proper categories (ergo plant asso- 230 Forestry Quarterly. ciations, forest types), based upon the types of vegetation found in it. Its delimitations are on the basis of the vegetative re- sponses to environmental conditions. Plant-ecology, on the other hand, is distinctly local. One part deals with the ecological signi- ficance of the morphological and physiological characteristics of the plants of a locality. The other part deals with the local minu- tiae of the vegetation of that locality (habitat), — with the relation of its vegetation units and their subdivisions to the climatic and edaphic conditions, etc., i. e. to the summation of their habitat com- plex. Forest-geography and forest-ecology are, of course, both branches of the broader subject of plant-geography and plant- ecology. It is never implied that other growth forms than trees are ignored in the former subjects, but only that the attention and interest are focused upon their forest rather than upon shrubby or herbaceous vegetation. Further, such investigations when made, not by botanists for botanical purposes, but by for- esters for forestry purposes, have features that serve to make the subject of silvics not coterminous with forest-ecology, as is sometimes supposed, but broader in scope, including such man- ner of investigations, for instance, as the effects of methods of brush disposal upon forest regeneration, the effects of fire dam- age upon the quantity and quality of the yield, etc., embodying technical questions of forest management belonging distinctly to forestry and not to botany. Hence silvics covers in large part the very ground of forest-ecology and yet, as well as this, covers also a part of the investigative field not included within the botanical subject of forest-ecology. Furthermore, the point of view of silvics throughout is different because of its different object. The forest-ecology of the botanists is concerned with adding to the sum total of botanical knowledge. Silvics of the foresters, on the other hand, is concerned with any and all forest investigations, whether of indirect or direct value, that bear in any way upon the practical questions of forest production. Dendrology — Its Scope. An examination of what the writer considers the specific scope of dendrology is now in order. Dendrology, the science of trees, as the word itself indicates, deals with tree species and not with communities of trees, not with forests. Within this still broad Scope of Dendrology in Forest Botany, 231 compass four distinct subdivisions may to-day be distinguished. Systematic dendrology dealing witii such characteristics' of trees, in their summer and winter conditions, as are of practical service in field identification. The distinctively winter charac- ters are usually not dwelt upon in botanical field courses. All this differs, too, from the taxonomic study of botanists in being confined exclusively to those characteristics that are of service in the field. In almost any botanical manual, except to some extent in the newer ones for trees designed along forestry lines, half or more of the taxonomic characters mentioned are not used in systematic dendrology, whose sole purpose is to afford a field basis for distinguishing one tree species from another, and not to present a complete taxonomic scheme. So much of botanical taxonomy as the forestry student requires belongs to his botanical study proper and not to his dendrological work in forest botany. Dendrology, in its four subdivisions as here detailed, covers a very wide range. The practical needs are for drawing its boun- daries closer rather than for extending them. Geographic dendrology, or the ranges of tree species. Biologic dendrology, or the systematic consideration of those characteristics of tree species that relate to their life-histories, pursued along non-ecological lines. This part of the subject verges upon the domain of silvics. Biologic dendrology is, how- ever, systematic, that is to say rather a recital of the facts in- volved in the climatic requirements of the species', their edaphic needs, habits of growth, tolerance, reproduction, and so on, than an analytical exploration of the ecological problems embraced within these matters, which properly belongs to the subjects of forest-ecology and silvics. Biologic dendrology may, indeed, fairly be thought of as preliminary to this. Quite aside from this' aspect of the subject as one preliminary to the study of silvics is its important aspect of furnishing the student of forestry with information that is indispensable to him from almost the be- ginning of his study of forestry, a selected array of facts that> he would best get first in clear-cut, systematic form, before in- volving himself in the far more difficult considerations of their ecological meanings. This has been recognized in educational practice to the extent that so far in the teaching of forestry in this country it has been largely biologic dendrology that has been taught rather than silvics, whatever titles may have appeared in 232 Forestry Quarterly. the curriculum. Silvics, with its immense significance for the attainment of substantial scientific results in forest investigations, remains, in its lack of scientific organization, one of the least developed technical branches of American forestry. Structural dendrology includes a consideration of the external features and structural elements of wood ; the value of macro- scopic and microscopic characteristics in identification and classi- fication; and the classification and identification of commercial woods. If dendrology is the science of trees then the study of wood structure belongs to it rather than to the srudy of forest products, which, as its title indicates, would be confined to the branches of wood technology or the application of wood in the arts, and to timber physics or the physical and chemical proper- ties of wood and minor forest products, both havmg to do with the woody product, while the structural features of the wood itself is more closely related to the science of the trees them- selves. Critical Bxaminaiion — Not Pedagogical Discussion. It should be distinctly understood that this paper presents a short critical analysis of the subject of dendrology, with some necessary preliminary explanation of the rest of forest botany, i. e. the ecological science of silvics, in order to make clear their relations', and does not present an outline of a plan for teaching dendrology. Hence it is not within the province of the article to discuss the various methods of presenting the dififerent parts of the subject to students. How many species' within different genera or groups of genera should be included for typical rep- resentation in a course in biologic or in geographic dendrology belongs to another topic altogether. The teaching of the differ- ent subdivisions must ever be subject to the exigencies of par- ticular cases, and, quite aside from the needs of any particular curriculum, the successful presentation of any part of the subject will, of course, always depend upon the individual initiative of the instructor. It seems, however, a ripe time for an endeavor to establish certain fundamental principles as to the scope of the subject that shall be abreast with the best present-day devel- opment. On the one hand it is highly desirable that foresters shall not confine the subject of dendrology to its systematic as- pect alone, nor solely to its systematic and geographic aspects, Scope of Dendrology in Forest Botany. 233 as is still being done in some places. And surely geographic dendrology, or the ranges of tree species, a single phase of den- drology, should not be taught under the title of forest-geography. The latter is a branch of the established science of plant-geogra- phy, the ecological science known internationally as phytogeog- raphy. It appears to the writer inadvisable to a high degree to attempt to take over one of its titles' to denote one single phase of the non-ecological science of dendrology. On the other hand, it appears to the writer equally inadvisable to go to the other extreme and endeavor to avoid the natural distmction between the non-ecological study of the various features of trees as indi- vidual species and the ecological study of forests as organic entities' by attempting to force all of this into one subject called dendrology. The best investigative tendency over all the world to-day is directly opposed to this course. And one of the chief present needs of American forestry is a solid scientific basis for its practice, a basis that can be secured only by the use of the best investigative procedures. The study of vegetation as the dynamic thing it is now recognized to be is immensely facilitated by this logical separating-out of all ecological matters. As direct witness to this may be cited the two established botanical sciences of plant-geography and plant-ecology, distinct signs of the times. Silvics, as conceived by the writer, is but the natural forestry outcome — forest-geography plus forest-ecology plus the widen- ing of the field through diflferences brought about in investiga- tions by the distinctive forest production pomt of view of for- estry. Practical Discussion Not Academic. While the essential problem in teaching what is considered in this paper as the subject of dendrology is obviously to cover the necessary ground, it is not, at the present stage of development of American forestry, whatever it might have been at an earlier stage, a purely academic matter to endeavor to determine and define the scope of its constituent parts and their place in the general scheme of forestry. It seems reasonable to account such systematizing quite as practical as the determination of a definite policy for the carrying out of any prolonged piece of work. It may, indeed, even be likened to the planning and outlining of the most advantageous route to follow in undertaking a long jour- 234 Forestry Quarterly. ney. One could probably arrive at his destination without such careful planning, but the best way to shorten a long trip is to do it. Nor are such plans ever iron-clad and unchangeable. Cer- tainly if forestry is to take its rightful place among scientific sub- jects its technical phases must be handled by scientific methods, and among these that of critical analysis with the object of a logical and therefore most useful classification of its parts is essential. Re-marks on Above Article: by the Editor. We agree most decidedly with the author in the last sentence, but we do not think that he has been altogether successful in securing a logical classification, although he has used much lan- guage in trying to secure it. The gist of his contention is that the term dendrology should be confined to non-ecological parts of the knowledge. We fail to see any logic in so circumscribing a self-explanatory term, which means "all about trees." Such circumscription is merely arbitrary, not forced by logic, and not acceptable or accepted. Dendrology is merely a segregation from the general field of botany of that part which concerns itself with trees. This part can be considered, like any other vegetation, from various points of view. The first point of view is from the standpoint of description of the material : descriptive dendrology — which may confine itself to the botanist's narrow point of view or extend to the dendrolo- gist's more complete analysis, including even wood-structure. As a result of the descriptive knowledge, we come to dendro- logical classification or taxonomy, a self-explanatory field of botanical inquiry limited to trees. We next come to study trees from the physiological point of view ; plant physiology with special reference to the physiology of arborescent forms. Last we may take up the biological (in the narrower German sense) phenomena of tree life, which includes phaenology and ecology of trees, i. e. a study of their cycle, of the causes of tree form, of their habits, of their biological requirements on the environ- ment, etc. This completes the whole field of dendrology. These subdi- visions are, of course, nowhere strictly limitable, for Nature defies our classification, which is only a device for limiting fields Scope of Dendrology in Forest Botany. 235 of inquiry practically and to enable us to overlook a large field of inquiry. But what about silvics? Before Dr. Gifford coined this unfor- tunate word — unfortunate because of its linguistically bad form! — the subject which it comprised was known to foresters — and botanists had nothing to do with it — as' "silvicultural character- istics of species." As this term explains itself, it is a segregation of the ecological knowledge (biological dendrology) which is of special interest to the silviculturist in the practical application of his art — the behavior of the species under forest conditions in- cluded. This very simple classification of the subject seems to us com- plete, and is hardly needful of argument, except for those that misuse terms and they are often incurable. The fact that a Committee for the Revision of Terminology of the Society of American Foresters has just begun its work, makes this discussion, however, timely. Remarks on the Above Article by C. D. Howe. The statement of the author that dendrology "deals with tree species, with facts concerning the individual trees that go to make up the forest," would include the study of the biological relationships of single trees. Such a study should be included under silzncs. Silvics is not alone a study of associations of trees as the author states. The term dendrology without a limiting adjective carries with it, I think, the idea of descriptive and taxonomic relationships. Dendrology might be included in the term forest botany, but silvics should not be so included. The study of biological re- lationships is a science co-ordinate with a study of the descrip- tive relationships, as in botany proper we have taxonomy (sys- tematic botany) and plant ecology, or as in zoology we have systematic zoology and ecological zoology. Therefore dendrolo- gy and silvics (granting the use of the term) should be regarded as co-ordinate branches, and only the former may be included under forest botany. Silvics is not a "sister" to plant geography and plant ecology, but is a daughter of the latter and only a cousin to the former From its derivation, plant ecology means the household relations. 236 - Forestry Quarterly. the home life of plants. Trees are plants. Therefore the study of the conditions of the home life of trees (silvics) is a sub- division of the study of the conditions of the home life of plants as a whole (plant ecology). Plant geography deals with the distribution of plants as indi- viduals or as aggregations. It locates and tabulates the habitats of these individuals or aggregates. It is a census of plant habi- tats. Strictly speaking, such a census could be made (and often has been made) with only a very general knowledge of the causes which have brought the habitats enumerated into existence. A knowledge of the conditions of a habitat and its resultant vegeta- tive structure, however, would increase the efficiency of a plant geographer. The plant geography of the past has been chiefly descriptive, while the modern plant geography is both descriptive and causal. The study of the causal relations is plant ecology; the application of such causal relations is plant geography. The one is concrete, the other discrete ; the latter, the application to wide areas of deductions from the intensive study of small areas. Therefore logically plant geography is a child of plant ecology. I am perfectly well aware that historically there has been no such relationship between them. In fact, so far as actual lineage is concerned the relationship is reversed, but we are discussing now a logical arrangement of the subjects. Since silvics is a subdivision of plant ecology, its relation to plant geography is the same as that of plant ecology one degree removed. Silvics is to forest geography as plant ecology is to plant geography. I can not see why the two terms Forest Ecology and Sihics may not be considered as synonyms. A forest ecologist study- ing only for botanical purposes would not lose caste by investi- gating the effects of brush disposal and fire upon reproduction. In fact an ecologist would have to go far afield nowadays to study vegetation unmodified by man. He is studying such modifica- tions continuously and he remains a botanist, not a forester or an agriculturist. To say that forest ecology stops the moment practical considerations enter, is similar to saying that the study of the chemical nature of wood is not organic chemistry because the results of the study may be applied to such practical consid- erations as the making of paper. Scope of Dendrology in Forest Botany. 237 Systematic dendrology. Here again the author is splitting hairs with the "practical" and the "scientific." A botanist dis- tinguishes herbaceous plants in the field by readily recognizable "ear marks." This does not make him any less a botanist. Biological dendrology. A forest is a collection of trees of the same or different species. The character of the forest is the sum of the characters of the individuals composing it. It seems to me that if one made a study of "the facts involved in the cli- matic requirements of tree species, their edaphic needs, habits of growth, tolerance, reproduction and so on," he would be making "an analytical exploration of the ecological problems embraced within these matters." But according to the author, if he performed the work indicated under the first quotation he would be in the domain of biological dendrology, while if he per- formed the work indicated under the second quotation he would be in the domain of silvics. I think this all I need to say of the author's attempt to separate the two. It is possible that there may be a logical division between the concept of biological dendrology and silvics, but the author does not make it clear. It is helpful in many respects to regard the forest as an organism, an entity, with its own structures and functions and with environmental interactions differing from those of an individual tree. The study of a forest from this point of view might be called silvics, while the study of trees in their ecological relationships as individuals might be called bio- logical dendrology. For example, the reactions of the forest as an entity upon light and temperature conditions, upon soil and hydrographic conditions might be considered as a distinct com- partment of forest knowledge. When, however, we begin to apply these reactions in their influence upon living plants, we must consider such plants as individuals, and then we fall back into the domain of biological dendrology as defined above. For example, if we study the influence of the forest as an organism upon reproduction a.'^■ expressed by the kind or the nature of the young growth, we are dealing with one of the components of the forest, not with the forest as a whole. I do not know, however, that the intergrading of these two concepts would be any greater than that of other divisions of forest knowledge. 238 Forestry Quarterly. Conk Borer vs. Squirrel. An Important Correction. Mr. J. i\I. Miller, Entomological Assistant, Branch of Forest Insect Investigations, Bureau of Entomology, and in charge of investigations of insect damage to forest tree seeds, writes the following : The January number of the Proceedings of the Society of American Foresters (Vol. IX, No. i) contains two articles on squirrels and sugar pine reproduction (pages 95-101). These articles are of some interest as I note that the description of damage to sugar pine cones, which is ascribed by both authors to squirrels', corresponds to that which I have usually found to be caused by the cone beetle. I would be interested to know just how close an examination was made of the sugar pine cones which were found on the ground during July and the first part of August. In Mr. Jotter's observations of August 20, 191 1, he re- cords 75 cones on the ground and only 6 of them eaten by squirrels, but the squirrel is evidently assumed as the cause of all the damage. There is a question as to whether or not the re- maining 69 cones showed teeth marks on the stem, which would indicate that they had been cut by rodents. I have examined great numbers of these cones which fall before maturing, yet have very rarely found the teeth marks of squirrels until just before the seed was ready to ripen. Practically all of these fallen cones did show, however, the attack of the cone beetle. Usually there was a tiny mass of pitch on the stem to indicate the entrance of the beetle, but where this was lacking either the beetle or presence of its attack could nearly always be found by close examination and sectioning of the stem. I am satisfied from observations made in different localities in California, that 90% of the damage to im- mature sugar pine cones, ordinarily referred to the squirrel, is caused by the cone beetle. This hardly seems fair to the squirrel. Both of these articles would indicate that the gray squirrel cuts the greater portion of the sugar pine crop before it ripens, thereby deliberately destroy- ing its own food supply. It is also worth noting that the exter- mination of the squirrel is recommended as a measure for pre- Cone Borer vs. Squirrel. 239 venting this loss to sugar pine. This measure would have little effect on the falling of immature sugar pine cones as long as the ravages of the cone beetle continue. These articles only emphasize the need of some published in- formation on the cone beetle. The material for a bulletin on this subject will be ready by the close of this season. CURRENT LITERATURE. Third Annual Report of the State Forester to the Governor, Slate of Oregon. Salem, Ore. 1913. Pp. 46. This third report of the State Forester is devoted to a record of the fire losses and to a statement of the fire protection work of the State and private agencies. Forty-six per cent, of the land area, or twenty-eight million acres, requires protection from fire. Sixteen million acres are protected by the United States Forest Service, while twelve mil- lion acres are patrolled on the co-operative basis by the state and private owners'. The average area burned over per fire on private lands has been reduced from 137 acres in 191 1 to 30 acres in 1913. Nearly 27,(X)0 acres of slashings were burned in accordance with the Oregon slash burning law. In 1913 a law was passed requiring every owner of timber land to provide a sufficient fire patrol for his land. This law has re- sulted in doubling the membership of existing fire patrol associa- tions and in forming several new associations. Half the report is taken up with detailed statements of the work of the sixteen fire patrol associations. The cost of protection in these associations ranged from one-half cent to three cents per acre. R. C. H. Annual Report of the Potlatch Timber Protection Association for ipij. Potlatch, Idaho. Pp. 16. This contains the annual reports of the President, Chief Fire Warden, and Treasurer of the Association. Eight members, paying assessments on 309,887 acres, (two and one-fourth cents per acre) are enrolled, but 594,000 acres lie within the boundaries of the Potlatch Timber Protective Asso- ciation and are regularly patrolled. The total acreage burned over in the season of 1913 was less than 70 acres, with injury to 13,000 feet of timber, which was promptly cut and used.

The Commission received in direct revenue (chiefly from hunt- ing and fishing licenses) $316,407.87, and spent $744,103.99. If timber could be sold from the state lands, the Commission would turn in a large surplus, the annual revenue from the sale of timber being estimated at $1,000,000. Special emphasis is placed on the problem of the water resources of the state, which is considered to be the most important con- sen.^ation question now needing attention. In the report of the Division of Lands and Forests, increased efficiency in fire protection and decrease in trespass on state lands is shown. New legislation is urged to permit the leasing of camp sites and the utilization of dead, down and ripe timber within the Forest Preserve. R. C. H.

It gives full details of the work accomplished during the year. One cannot peruse its pages without being im- pressed by the variety and amount of work under way. A decade has passed since the establishment of the office of State Forester. Substantial progress has been made in this first decade, and indications point to even more rapid development in the next ten years. In 19 1 3 the first organized attempt was made to apply forestry to the moth problem, and wath distinctly successful results. The object aimed at is to encourage tree growth which will furnish unfavorable food for the moths. This is done by cutting out the non-resistant species, such as oaks, willow, cherry and gray birch. Both trees and brush on which the moths like to feed are removed. The final result will be the replacement of oak forests by pine, ash and a few other resistant species. 242 Forestry Quarterly. A relatively intensive survey and mapping of the forests of the state has been started. Among the recommendations of the State Forester for future work are the following: — 1. Development of state forests on a more pretentious scale than is now possible under the reforestation act. 2. Enactment of legislation to regulate disposal of slash, 3. Change in present methods of taxing forest land. R. C. H. The Woody Plants of Kentucky. By H. Garmen. Bulletin 169, Kentucky Agricultural Experiment Station. Lexington, Ky., 1913. The author of a tree flora is confronted with two problems, each capable of consuming the bulk of the manuscript and both essential to a complete flora. The first is the proper presentation of the distinguishing characteristics of the trees, and the second is the detailed account of their distribution. Consideration of the distinguishing features of the species is perhaps of greater value to resident students, while detailed range data is of great interest to outside investigators who are concerned with the geo- graphical distribution of trees. A detailed account of the tree ranges by counties may not be of as much assistance to resident students as would a work with keys and distinguishing descrip- tions, but to the outside investigator who has ample references on these botanical distinctions, it is of great value, as it gives specific information as to just what species may be found in the state and in what situations they occur. An ideal preliminary list undoubtedly is one which presents dis- tribution data in the greatest detail and gives the authorities for those trees reported but whose presence seems quite doubtful on account of their range outside of the state. Distribution of such a preliminary list necessarily brings to the author many range ex- tensions, corrections and confirmations which could not be secured in any other manner. In this bulletin such emphasis has been placed upon detailed distribution data. Stating that the work is to be regarded as pre- liminary to a more complete account of the woody plants of the Current Literature. 243 state, the author presents an interesting historical account of botanical work in the state. The character and peculiar features of the forest flora are then discussed, together with the influences which may have been operative in limiting the ranges of species. The author notes that owing to the intermediate position of the state, northern and southern species are here associated. Twenty- two of the eastern oaks and all of the elms are represented. It is noted that all of the ashes probably occur in the state, although pumpkin ash {Fraxinus profunda) has not been found on the Kentucky side of the Mississippi. The statement, however, is not corroborated by the list of species, as Fraxinus caroliniana and its near relative, Fraxinus pauci flora are not mentioned and do not grow in Kentucky, Of interest, is the record of Finns palustris in Kentucky, as re- ported by Lafayette De Friese from near Pound Gap. Although this observation was made many years ago and at a time when the forest flora of Kentucky had not been disturbed by farming and lumbering operations, yet the author very properly questions such an unexpected northern range extension of this southern pine. It is observed that soil influences appear to have less control on the distribution of Kentucky trees than have climatic influences and means of dispersal. With one exception, the trees all appear to grow on almost any soil, if only climatic conditions are not un- favorable. Chestnut alone appears to be influenced by the char- acter of the soil and is found almost entirely in soils containing sand. It can be transplanted to the clay loams of the Bluegrass Region but does not grow there spontaneously. The author presents a list of species, following the arrange- ment of the seventh edition of Gray's Manual. A question mark precedes the names of species w^hose presence is doubtful and the authorities are given for those species reported by other investiga- tors but not observed by the writer. A brief note on special pecul- iarities of the plant is added and a detailed statement of its dis- tribution by counties is included, which constitute a most valuable record. A number of half tones and line drawings of trees are added. In some of these (Bur oak, magnolia, and holly), no ad- vantage has been taken of the great refinement in line which may be secured by drawing for reduction, but they are sufficiently ac- curate to add to the value of the volume. On account of the large number of our eastern hardwoods 244 Forestry Quarterly. which have either their northern, western or southern line of termination passing through Kentucky, this pubhcation will be greatly appreciated by investigators who are concerned with larger problems of forest distribution. W. H. L. Forest Tree Diseases Common in California and Nevada. A Manual for Field Use. By E. P. Meinecke, Forest Pathologist, Bureau of Plant Industry. U. S. Forest Service. Washington, D. C. 1914. Pp. 67. "This manual, designed for practical use in the field, discusses only the more important tree diseases found in California and parts of Nevada, though most of them are common also in other forest regions. Its aim is to enable the field man to determine the cause of the commoner diseases and injuries and to under- stand their effect on the living tree. It discusses also ways and means of control of fungi and mistletoes, as well as climatic, bio- logical, and soil conditions which bring about diseases in forest trees." The above opening paragraph of the manual states admirably the scope of the publication. The author deserves much credit for successfully presenting a highly technical subject in popular form well adapted to the use of forest rangers and other field men. Before entering into a discussion of the common tree diseases and the fungi which cause them, several pages are devoted to a brief, comprehensive description of the structure and normal functions of the tree, as a basis for the understanding of disease which the author defines as an unbalancing of normal functions. This is followed by a brief discussion of disease and its more common causes in trees, methods of examining and diagnosing abnormalities, and a description of the more common symptoms of poor health. The nature and development of fungi, their mode of growth and their effect on plant tissues are next discussed, and the more common forms of their fruiting bodies are described. The description of the diseases of trees is divided into two parts ; first, the diseases affecting the increment, that is the future timber supply, and second, the diseases affecting the present supply of timber. Current Literature. 245 Under the first are discussed the various more common needle diseases such as Lophodermiiim and Hypoderma. The incense cedar rust, {Gymnosporangium bias d ale antim) , and the pine gall fungus (Peridermium harknessii), are described at some length. Among the more important diseases of the second group dis- cussed are the following : Fomes annosus, which is very destructive to trees in Europe and Eastern United States, but which is as yet not dangerous in California. Trametes pini, the ring scale fungus, which is the cause of destructive diseases of mature and overmature conifers. Fomes laricis, the chalky quinine fungus, which causes red heart- rot in various valuable conifers, including the sugar pine. ^0/3;- porus sulphiireus, the destructive sulphur fungus, most often found on oak, chinquapin and red fir, but occurring also on Douglas and white fir, and yellow and Jeffrey pine. Polyporus aiiiarus, which in producing dry rot of incense cedar, causes enor- mous damage on the Pacific Coast. Polyporus schzifeinitsii, one of the most serious enemies of Douglas fir and which also occurs on certain pines and on white fir. Fouies pinicola, the red-belt Fomes, which is the commonest timber-destroying pore fungus in California, attacking all the important conifers except incense cedar, juniper, redwood and bigtree. Polyporus dryophilus, which causes a destructive heartrot in living oaks. Fomes igni- arius, the false tinder fungus, which is confined to the deciduous trees and is especially common on willows, cottonwood and quak- ing aspens, causing a white heartrot which sometimes extends into the sapwood. Bchinodontmm tinctorum, the Indian paint fungus, which is one of the most common wood-destroying fungi in Cali- fornia, found almost exclusively on white fir, causing the char- acteristic stringy brown rot. This is the fungus, the effect of which has brought the white fir into great disfavor among the lumbermen. ArmiUaria mellea, the honey fungus, which is one of the most destructive root fungi of oaks and orchard trees. It is not very common in our forest trees, but sometimes attacks coniferous trees of all ages, often spreading through diseased roots to roots of sound neighboring trees which it kills in a short time. 246 Forestry Qnurterly. Several pages are then devoted to the two types of mistletoes found in California, Phoradendron and Rasoumofskya, v^hich latter are the common causes of witches' brooms on coniferous trees. The manual concludes with a discussion of the practical methods of controlling tree diseases. Two general rules for con- trol are laid down : First — Save the merchantable timber of a tree as long as the amount to be saved justifies it. This simply means closer utili- zation of our timber supply. Second — Prevent the infection and infestation of sound timber by getting rid of all diseased and in- sect infested living or dying trees. This means sanitation of our forests. "Systematic elimination of the common fungi or mistletoes will take many years. The method which gives the best results is illustrated by a stipulation inserted in the Forest Service timber sale contracts. This requires the purchaser to cut all trees marked apon the cutting area, whether merchantable or apparently un- merchantable. Trees must be opened up sufficiently to satisfy the Forest officer in charge of their condition, and any logs in such trees which, in his judgment, are merchantable, must be removed from the woods, scaled and paid for. This enables the Forest Service to get rid of all undesirable stuff and to leave only sound seed trees and sound reproduction in healthy surroundings. It also makes possible utilization of merchantable timber left in un- desirable trees, which would otherwise go to waste." L. M. Forest Management of Loblolly Pine in Delazvare, Maryland and Virginia. By W. D. Sterrett. Bulletin 11, Department of Agriculture. Contribution from the Forest Service. Washington, D. C. 1914. Pp. 59. This bulletin covers the subject of the management of this species in a comprehensive manner, and it is presumed repre- sents the results of a large amount of data collected during past years by the Forest Service in the states mentioned. The tables are especially valuable, those on costs and net profits should be helpful to private owners, and those on growth and volume to the professional forester. Current Literature. 247 The recommendations under Fire Protection for piling and burning slash after lumbering are of doubtful value to private owners of loblolly timber since it is not believed that these rules can be profitably carried out. Before even a very rough system of fire protection can be inaugurated there must needs be practical and comprehensive state laws enacted by the states concerned in this bulletin, and especially in Virginia, where such rudimen- tary laws as exist at present are inoperative. A hopeful sign, however, is that in Virginia at the present writing the question of up-to-date and efficient forest laws is being seriously con- sidered, and it is hoped that such bills may be enacted into law by the present State Legislature. There must, however, ensue a long period of education and publicity before such laws, if passed, will become really effective. An unusual omission in the publication is that nowhere in its fifty-nine pages is the scientific name of loblolly pine mentioned, not even under the paragraphs Forest Types and Characteristics, nor even in the Appendix under Nomenclature. It is understood, of course, that Pinus taeda, Linn, is referred to. Associated species are honored with their scientific nomenclature but the species whose adaptability to forest management is so fully dis- cussed is overlooked. From the writer's personal knowledge of the species in Vir- ginia he doubts the absolute accuracy of the range of botanical distribution as shown on the map on page 3, believing that the species is found considerably farther west in the Piedmont Plateau than shown on the map. On the whole, the bulletin is a valuable contribution on this economically important species, and should be very helpful to the private owner of loblolly stands as well as to the consulting forester. J. D. G. The Reseeding of Depleted Grazing Lands to Cultivated For- age Plants. By A. W. Sampson. Bulletin 4, Department of Agri- culture. Contribution from the Forest Service. Washington, D. C. 1913. Pp. 34. Excellent results have been secured in reseeding depleted ranges to cultivated forage plants on certain of the national forests where this system has been inaugurated. The best results were obtained 248 Forestry Quarterly. by sowing a mixture of timothy, red top and Kentucky blue grass on moist mountain meadows, sowing 16 pounds of seed per acre and brushing it in with a brush drag, at a total cost of $1.40 per acre. Timothy gave the best results in these studies and October is named as the best month of the year for sowing. Reseeded areas should be very lightly grazed during the first year. J. H. S. Range Improvement by Deferred and Rotation Grazing. By A. W. Sampson. Bulletin 34, Department of Agriculture. Wash- ington, D. C. 1913. Pp. 16. This report gives the results of three years' study of range grazing and its effects on the principal forage plants. It is written in a popular style and is apparently intended primarily for grazers and range managers, as well as for federal forest officers. The results secured by this study give information of great value on the proper seasons for grazing summer ranges, a problem on many national forests. It is clearly shown that close grazing in the early spring and summer months prevents reproduction of palatable plants by retarding seed maturity, and results in an in- crease of the non-palatable species and a decrease in carrying capacity. The figures secured show that the best results can be obtained by close grazing in the late summer, after seed has ma- tured, at which time the grazing animals tend to thresh out the seed and trample them in the ground, which answers the purpose of harrowing. J. H. S. The Shrinkage in Weight of Beef Cattle in Transit. By W. F. Ward. Bulletin 25, Department of Agriculture. Contribution from the Bureau of Animal Industry, Washington, D. C. 1914. Pp. 78. Some interesting and valuable figures to the forester, who must know facts outside of his forestry work, are contained in this bulletin on the shrinkage of beef cattle in shipment, covering three years' study in the southwest and the northwest. That the method of handling cattle, the distance they are driven from the range to the loading pens, and the fill given them just before loading play an important part in the per cent, of shrinkage en route are clearly brought out in this report, but for the reasons given above, Current Literature. 249 the figures given in the tables can be considered as only ap- proximate. The old practice of giving a herd a light v^ater and 3 or 4 hours grazing before loading is shown to be better than giving the cattle a good fill, or none at all, and the reasons for this are also clearly shown. Taking an average of the shipment, the re- port shows that the shrinkage is greater on fed cattle than on range cattle. This is due largely to the fact that most range cattle are driven a considerable distance to the railroad and some shrinkage takes place before they are loaded, while fed cattle are usually loaded close to the feeding place and have not yet begun to shrink when they go in the cars. It is found that as a general rule bulls shrink more than any other class of cattle, with cows a close second. Heifers shrink less than cows and steers less than heifers. Calves shrink less than the other classes but the general average in proportion to weight is close to that of steers. It is unfortunate for foresters on the national forests that this study did not include figures on the shrinkage of cattle from the time they leave the range until they are loaded, since had such figures been given the study might have been of very great value in the utilization of unused range, which is to be found on many of the national forests, and which is a problem confronting many federal forest officers at the present time. J. H. S. The Gipsy Moth and the Brozvn-Tail Moth, ivith Suggestions for their Control. By A. F. Burgess. Farmers' Bulletin 564. Washington. 191 4. Pp. 24. This bulletin summarizes the past and present status, the life history, food plants, injury caused, natural and introduced ene- mies, and methods of control of the gipsy and brown-tail moths in a way to be of great value to the citizens of the northeastern states. A map showing the area infested by and quarantined for these moths is an interesting feature. The habits of the moth are too well understood to need repetition, but conclusions in regard to methods of control are worthy of note. Orchard, street, park and ornamental trees can be protected without prohibitive cost by methods now generally employed. "The control of these insects in forests is extremely difficult, owing to the small amount of 250 Forestry Quarterly. money that any owner can afford to expend in preventing injury to his woodlands." "Experiments have shown that coniferous trees are not injured by the gipsy moth if grown in isolated pure stands, and if the growth is such that the trees can be thinned to a stand of coni- fers no hand suppressive measures are necessary in order to pre- vent injury by this insect. (See fig. 10.) Such lots will also be immune from attack by the brown-tail moth, as the larvae of this insect do not feed on conifers. "If mixtures containing a large percentage of deciduous trees are to be protected from moth injury, it is very necessary that the species involved should be carefully considered before a decision is reached as to the best methods of treatment. Sometimes prac- tical methods of thinning can be adopted so that species will be left that are only slightly subject to injury by these insects. A limited number 01 experiments have shown that mixtures of chestnut, pine, red maple, ash, and hickory, regardless of the pro- portion of each species, are seldom injured by the gipsy moth. "In woodlands the oaks are the most favored food plant of this insect, and unfortunately the infested region abounds in large areas where these species predominate. At present there seems to be no means aside from hand treatment which will prevent serious injury to oak woodland. . . . "This problem is being given special study and consideration in the hope that some economical method may be devised for pro- tecting and improving wood lots of this character at moderate expense. . . . "The damage caused by the brown-tail moth is ordinarily not so severe as is that resulting from gipsy-moth infestation because the former species does not have so wide a range of food plants and, further, because the bulk of the feeding is done early in the season so that the trees have an opportunity to recover before midsummer. In the territory where both insects exist the cater- pillars of the gipsy moth supplement the work which is done by those of the brown-tail moth and the injury^ is therefore greatly increased. The large acreas of oak-sprout growth furnish abun- dant food for brown-tail moth caterpillars. . . . "Elimination of oak, scrub apple, and wild-cherry trees would assist greatly in reducing the numbers of this pest." At the present time both the New England States and the Current Literature. 251 United States Bureau of Entomology are engaged in the fight against the moths. The United States Forest Service is' carrying on silvicultural investigations to determine whether a practicable system of forest management to hold the insects in check can be devised. The final conclusions of the writer are expressed in the follow- ing paragraph and are in general encouraging: "During the past season conditions in the oldest infested area have not been as serious as in previous years. The records show that the mortality of the gipsy moth and brown-tail moth cater- pillars as a result of the attack of parasites, predaceous enemies, and disease has been greater than in any of the years preceding. The experiments which are being conducted are giving informa- tion which will serve as a basis for handling infestations more satisfactorily and economically, and although new territory has been found infested the outlook for diminishing the aggregate amount of damage which results from the work of these insects is more favorable than it has been heretofore. It is necessary, however, that aggressive measures should be continued in order that the pests may be brought under better control." R. C. H. Forest Fire Protection by the States.

This is a detailed record of the proceedings of the conference held in Washington on January 9-10, 1913, between representa- tives of the United States Forest Service and other parties co- operating in fire protection under the provisions of Section 2 of the Weeks Law. Valuable information is given on various phases of forest fire protection from Maine to Washington and south through the Appalachians.

Forest Service. Reprint from Bulletin 161, American Railway Engineering Association. 1913. Pp. 163-231. This valuable publication comprises the various data collected by the Forest Service in regard to the air-seasoning of cross-ties' and, to a less extent, of poles and sawed timbers. Much of this has already been published in various circulars and bulletins, but the present work brings all of it together in comparable form and adds considerable data not previously made public. It is all too evident, however, that much remains to be done before our knowledge of this important subject is satisfactory. The cross-ties tested were procured at monthly intervals throughout the year and each month's cut piled in different ways so as to ascertain the effect of the form of pile on the rate of seasoning. The piles of 50 ties each were exposed to the weather without cover other than that afforded by the solid tier of ties on top. The progress of the seasoning was determined by weighing each tie at intervals usually of a month. The data from these experiments is presented graphically in numerous curves. Seasoning experiments on western yellow pine, white fir, and Douglas fir were conducted at Pecos and Rociata, New Mexico, where the elevation is between 7,000 and 8,000 feet above sea level. Ties cut in January and February required from 4 to 5 months to reach a constant moisture content ; those cut in May and June only 2 months at Rociata and i month at Pecos ; those cut in November and December, 6 months. There was not much variation in the rate of seasoning of the different species. Lodgepole pine, Douglas fir, and western larch of the North- west were tested. Lodgepole cut in Montana in May, June or July was practically air-dry in 3 months, and even when cut in September became fairly well seasoned before winter; but if started in winter it required until the next July to become dry. Larch in Idaho and Douglas fir in Idaho and Washington, when cut in early spring, required from 4 to 5 months to season, while if cut in July they lost almost as much moisture in the succeeding 2 or 3 months as they did by holding them until the following summer. Local climate effects on seasoning were shown by tests at Tacoma in the western and at Pasco in the eastern part of Wash- Current Literature. 253 ington. Both lots of ties came from the same place and the weights were taken at the same time, but the seasoning was more rapid and a lower rate was reached in the drier climate at Pasco than at Tacoma. Of the eastern conifers only hemlock and tamarack ties from Michigan have been tested. The hemlock had a very high mois- ture content when green and lost water rapidly during the sum- mer months but did not reach a constant weight within the period of the observation which varied from ii to 16 months. There appeared to be practically no difference in the rate of seasoning of ties openly piled (7x2 and 8x1) and those closely piled (7^:7). It required from 4 to 9 months, according to the time of year, to reduce the moisture content of hemlock from a green weight of 55-57 pounds per cubic foot to 40 pounds, while the average dry weight of the wood is only 24 pounds per cubic foot. Seasoning records were obtained on loblolly, longleaf, and shortleaf pine at Silsbee, Texas, and on loblolly at Ackerman, Mississippi. Ties cut in January and February were fairly dry at the end of 4 or 5 months, but continued to lose weight for several months longer. From April to October the seasoning was so rapid that the ties lost little weight after the first 2 or 3 months, even if held till the following summer. Tests were also made on some southern hardwood ties. Hard- woods in general dry more slowly than conifers. Red oak ties cut in Arkansas in spring and early summer were far from dry when they ceased to lose weight at the approach of winter, and the following summer they lost nearly two-thirds as much moisture as during the first summer. When the ties were cut in winter and carried through two years the loss of weight during the second summer was nearly half that of the first. The tests on other hardwoods were not conclusive but indicated that red gum and beech dry faster than red oak. Data on the rate of seasoning of northern hardwood ties are very meagre. The data on the pole-seasoning tests will not be reviewed here as they are presented in the present publication in only slightly different form from Bulletin 84, "Preservative Treatment of Poles." The accelerating effect of wann, dry weather on the rate of evaporation, and the retarding effect of cold, damp or wet weather are plainly visible in the tests started at different times of the 254 Forestry Quarterly. year, and also when the weighings were continued from one sum- mer through the winter into the succeeding summer. Timbers which had become fairly dry ceased to lose or even absorb moisture during rainy or cold, damp weather. Timbers cut under such conditions showed a moisture loss regardless of the weather, and by the time warm, dry weather arrived their seasoning had advanced so far that the rate of loss was fairly constant through- out both periods. "Of two pieces of wood differing in moisture content, other conditions being equal, the one with most moisture will dry the more rapidly, and in a comparatively short time both pieces will reach about the same condition. This rule does not apply strictly between different species, even when of similar structure and in pieces of the same size and form, but with conifers the usual variation between the species does not seem sufficient to neces- sitate separate treatment. "Sapwood of the conifers contains, as a rule, very much more moisture than does the heartwood, and the difference in the pro- portion of heartwood and sapwood in two timbers of the same species accounts for a large part of the difference in moisture content, But sapwood loses moisture more rapidly than the heart- wood, and this tends to equalize the time required for the two pieces to become air-dry. . . . "The complaint is not at all uncommon that cross-ties or other timbers of certain species, such as the soft pines, the gums, beech and maple, will decay before they will season. It is believed that this can be prevented usually by piling the timbers so as to dry rapidly. The tree should be barked as soon as felled, and the timbers piled openly. Injury by insects may be prevented in the same manner. "While quick seasoning prevents injury by decay and insects, it is not always necessary or desirable. Timber cut and set dry- ing in hot weather checks more seriously than in cold weather, and sometimes becomes 'case-hardened' and very resistant to pre- servative treatment. Timber cut in the late autumn or winter seasons more slowly and evenly; if peeled and properly stacked, or skidded off the ground, it dries enough before warm weather to resist attack by insects or fungi. But whatever the time of cutting, careful attention is needed in piling the timber, either Current Literature. 255 more openly or more closely, according as local climatic and other conditions are found to require. . . . "The extreme rapidity with which saturated wood loses mois- ture when exposed to dr}'ing conditions is doubtless responsible for the belief that the seasoning of timber may be facilitated by soaking it in water. In the tests to determine the etfect of this process, timbers which had been soaked for short periods, upon removal from the water, lost the extra moisture so fast that they soon reached practically the same condition as similar timbers not immersed. Whether the soaked timber ultimately reaches a lower moisture content is still open to question." S. J. R. Tests of Wooden Barrels. By J. A. Xewlin. Bulletin 86, U. S. Department of Agriculture. Washington, D. C. 1914. Pp. 12. This paper describes tests made at the Forest Products Labora- tory in co-operation with the Bureau for the Safe Transportation of Dangerous Explosives, the purpose being to obtain data upon which specifications and changes in the design of wooden barrels used in the transportation of dangerous liquids might be based. The tests do not afford comparisons between barrels made of dif- ferent material or of different kinds of timber. The barrels which were made of quarter-sawed white oak, were completely filled with water, closed and tested. Two barrels of each group v/ere tested in side compression, two in diagonal com- pression, one each in side and diagonal 'drop, and two by internal pressure. The tests indicated that the chimes should not be less than one inch long ; that the spacing between the bilge hoops should not be less than eight inches ; that the weakest part of the barrels was the heads which should be much thicker than the staves; that the dowel holes weakened the heads materially, making desirable some improvement of the head joints ; that it is advisable to grade the staves and heading with reference to the strength. S. J. R. 256 Forestry Quarterly. Tests of Rocky Mountain Woods for Telephone Poles. By Norman de W. Betts and A. L. Heim. Bulletin 67, U. S. Depart- ment of Agriculture. Washington, D. C. 1914. Pp. 28. This paper gives the results of tests on western red cedar, lodgepole pine, and Engelmann spruce poles to determine their suitability for telephone poles'. The tests included fire-killed pine and spruce. Although pine and spruce are not naturally durable in contact with the ground, the general adoption of preservative treatment by railroad and telephone companies would permit their use if otherwise satisfactory. On a basis of the fiber stress developed, the air-seasoned lodge- pole pine is superior to the cedar in all of the mechanical pro- perties tested. Fire-killed lodgepole pine proved to be only 80 per cent, as strong as the cedar, but in elastic values was prac- tically equal to it. Fire-killed Engelmann spruce was found to be inferior in all mechanical properties to the cedar and pine. Since a comparison based on the fiber stress developed is equivalent to one based on uniform ground-line diameter, while in practice it is customary to specify top diameters, it is evident that a difference in taper, such as ordinarily exists between poles of the different woods, would afifect the strength of the poles. On a basis of equal top diameters it appears that there is practically no difference between air-seasoned lodgepole pine and western red cedar, while in stififness the pine exceeds the cedar by about 25 per cent. The fire-killed poles of both lodgepole and spruce were practically equal to the cedar in strength at elastic limit and about 20 per cent, below it at maximum load. S. J. R. Balsam Fir. By Raphael Zon. Bulletin 55, U. S. Department of Agriculture. Washington, D. C. 1914. Pp. 67. This paper deals with all aspects of balsam fir, its distribution, the forest types in which it occurs, the present stand and cut, its economic importance, particularly in relation to the pulp industry, methods and cost of lumbering, life history of the tree, char- acteristics of the wood, rate of growth and yield, and suggested methods of management. The total stand of balsam fir throughout its range is roughly Current Literature. 257 estimated to be five billion board feet which, not counting the in- crement, should last thirty years at the present rate of cutting. The principal objections to the use of balsam for pulp are: (i) In the ground-wood process the pitch covers the felts and cylinder faces. The writer contends that this is not due to any property of the wood itself, and must either come from bark left on the surface of the blocks or else is formed in the process of grinding. The statement is made that balsam fir is one of the fezv conifers that lack resin ducts entirely, when as a matter of fact only four out of thirteen indigenous genera contain ducts normally. (2) The fiber of balsam fir is weaker, shorter, and softer than spruce fiber, (3) The yield in paper and pulp per cord of wood is less than in spruce. Under present methods of cutting, balsam fir is increasing at the expense of red spruce in the second growth throughout the entire range of the two species. The fir grows much faster throughout its whole life than the spruce, but is shorter lived and reaches maturity very much sooner. The fir should be cut at an age of from 100 to 125 years, while spruce as it now grows in natural forest should be cut at an age of from 175 to 200 years. The annual increment per acre of balsam over its entire range varies from one-sixth to one-third of a cord. Selection cutting in small groups is recommended as the best silvicultural system for balsam. The natural reproduction of both spruce and balsam is assured under this system, with the pos- sibility of increasing the proportion of spruce in the new stand. S. J. R. Tyloses: Their Occurrence and Practical Significance in Some American Woods. By Eloise Gerry. Reprint Journal Agricul- tural Research. U. S. Department Agriculture Vol. i. No. 6. 1914. Pp. 445-470- This paper embodies the results of a careful study of a con- siderable number of specimens of both hardwoods and conifers with reference to tyloses. Emphasis is laid on the previously known fact that tyloses may occur in the sap wood of all species in which they occur in the heartwood, sometimes in the outer- most rings near the bark. Attempt to explain the relation of tyloses to the properties of 258 Forestry Quarterly. the wood is not very satisfactory. "The woods in which tyloses are abundant as a rule are durable," yet there is nothing to prove that the presence of the tyloses is in any way responsible for the increase in durability. It is shown that tyloses when strongly de- veloped in the vessels of wood tend to keep air and liquids out of the vessels, but in the case of impregnation of the wood with creosote they apparently have no effect on the penetrability of the other wood elements. This paper may well be considered a valuable contribution to the knowledge of the subject, but more so because of the ques- tions it raises than those it settles. Much remains to be learned regarding the "practical significance" of tyloses. The plates are excellent and demonstrate the great possibilities of photomicro- graphy in the study of wood structure. S. J. R. A Meteorological Study of Parks and Timbered Areas in the Western Yellow-Pine Forests of Arizona and New Mexico. By G. A. Pearson. Reprint from Monthly Weather Review. Wash- ington D. C. Vol. 41, 1914. Pp. 1615-1629. The object of the study was to determine the influence of the forest cover upon climate locally in the Southwest, in so far as this influence might be of importance in the management of timberlands and the possible afforestation of parks and denuded areas. Comparatively little attention was devoted to purely me- teorological problems or to the influence of the forest upon the general climate of the region. It was found that the mean annual temperature in the forest is 2.7° F. higher than in the park, and the maximum averages 0.9° F. lower and the minimum 6.4" F. higher. The mean daily range is y.^'^ F. smaller in the forest. This relation is believed to be due to the influence of the forest canopy, partly by the action of the tree crowns in checking the loss of heat by radiation, but mainly by the deflection of cold air currents from surrounding mountains and high mesas. The temperature of the soil in the forest during the summer, when shaded by the trees was found to be about 5° F. lower at a depth of two feet than at the same depth in the park. The snowfall in the park is more even and the depth some- what greater than in the forest where the crowns of the trees in- Current Literature. 259 terfere, but it remains from two to three weeks longer on the ground in the forest and a greater proportion of the snow water is absorbed by the forest soil. The average wind movement in the forest is only about half as great as in the park, while the evaporation from a free water surface is only 70 per cent, as great. "The influence of the forest upon all factors studied, with the exception of relative humidity for which our data are inadequate, is similar to that shown by European observations. In the European forests, as in those covered by this study, the extremes of temperature are modified ; but in European forests the maxima are lowered more than the minima are raised, with the result that the mean temperature is lowxr in the forest than in the open, while in our forests the maxima are lowered less than the minima are raised, with the result that the mean temperature is higher in the forest than in the open. The influence of the forest in de- creasing evaporation is 30 per cent greater in Europe than is shown in this study." This investigation shows that the climatic conditions are de- cidedly unfavorable to the establishment of forest growth in the parks, and that little or nothing can be expected from natural seeding. In cutting original stands it is highly desirable to leave a portion of the stand not only to furnish seed but also as a pro- tection to the young growth. The Forest Service had previously adopted this shelterwood system and this report states that the reasons for doing so are well founded. Some planting experiments of 1912 gave excellent results, due presumably to the use of a higher grade of plants than had pre- viously been tried. There is no assurance, however, that the planta- tions will grow to maturity, as it is probable that unfavorable soil conditions, as well as adverse atmospheric conditions which make it impossible for the seedlings to survive the first year, are in- volved. Although the most of park areas in the yellow-pine type will eventually be devoted to agriculture, yet there are some portions too rocky for farming which should be forested if pos- sible. "Further investigations on cut-over areas, with special refer- ence to the efifect of dififerent degrees of cutting upon the physical conditions which are now being conducted by the Fort Valley Forest Experiment Station, will undoubtedly determine with 26o Forestry Quarterly. greater scientific certainty how our western yellow-pine forests should be managed. This study merely attempted to lay the scientific foundation upon which to base the broad principle of forest management of western yellow pine in the Southwest." S. J. R. Anfiual Report of the Director of the Department of Botanical Research. By D. T. MacDougal. 1913. Pp. 1-87. Dr. MacDougal's annual report contains an interesting account of the treelessness of the prairie regions, by W. A. Cannon, and the root characters of trees grown in the coastal climate of Cali- fornia, by the same writer. It appears that "Mesophytic trees should attain a perennially moist soil — such resistant species as mesquite may persist — if the water table lies within 40 feet of the surface." In Kansas and Nebraska the water table is often less than 40 feet along streams, but on adjacent higher lands it is from 60 to several hundred feet, where, although the soils may be favorable, forests are unable to exist. The open character of the oak forests so typical of Southern California, Dr. Cannon found, were directly the result of far-reaching superficial roots. T. S. W. Jr. Makers of British Botany. A Collection of Biographies by Living Botanists. Edited by F. W. Oliver. Cambridge Uni- versity Press. 1913. Pp. 332. This book consists of a series of delightful essays on the life and work of outstanding British botanists of the past, from the earliest down to Sir Joseph Dalton Hooker who died in 191 1 — Morison (1620-1683), Ray, Grew, Hales, Hill, Robert Brown, William Hooker, Henslow, Lindley, Griffith, Henfrey, Harvey, Berkeley, Gilbert, Williamson, Ward, and Joseph Dalton Hooker. The title is not a happy one, for neither has there been a school of British botany as distinct from German, Italian, or any other, nor does the editor make any such assumption. British botanists have taken a part in most of the important ad- vances made in the science of botany and some have been pioneers. Current Literatttre. 261 Morison and notably Ray were among the first to successfully attempt a rational classification of plants. Grew shares with the Italian botanist Malpighi the distinction of laying the founda- tions of plant anatomy. It is noteworthy that Grew's Anatomy of Plants (1672) appeared the very day on which Malpighi's manuscript was submitted for publication. Hales was probably the first plant physiologist (1727), standing "in the solitude of all great original inquirers." Brown was foremost among modern morphologists, worthy of Von Humboldt's estimate of him — "facile botanicorum princeps." The elder Hooker occupies a place with the elder De Candolle of Geneva, as a great descrip- tive botanist, the last of the pre-Darwinians, and as an organizer of botanical gardens — his name is indissolubly associated with the making of Kew. Henslow was a pioneer ecologist and botanical educationist. Lindley (1799-1865) linked botany with horticulture. Gilbert (1817-1901) has done the same with agri- culture, making the Rothamstead experiment station perhaps the best known of all its kind. Harvey was a pioneer algologist, and was the first to give an account of the seaweeds of our continent in a magnificent work published by the Smithsonian Institution (1858). Berkeley ranks as a foremost mycologist, and "it is not too much to pronounce Berkeley as the originator and founder of Plant Pathology." Some measure of the extent of his labors is possible when it is remembered that in his herbarium of fungi presented to Kew in 1879 — 10,000 species in all — 5,000 were types of his own description and naming. Williamson leads in the van of British palaeobotanists. Joseph Hooker fills a large place as a systematist of the post-Darwinian era. His natural system of classification (Bentham and Hooker's) held the field for a gen- eration. It was the immediate predecessor of the Engler system now in vogue. Ward was among the first to apply strict bacterio- logical methods to the study of fungus diseases of plants. He was associated for a time with a forest school, and published the well-known Manuals on Trees.

FOREST GEOGRAPHY AND DESCRIPTION. An article by Barbey summarizes the de- Forest velopment of forest practice m Switzer- Bvolution land. After explaining that forestry was in not originally homogeneous on account of Switzerland. Switzerland being divided into twenty-two federations, he shows that the birth of real forestry in Switzerland was in the eigh- teenth century when the first silviculturists were trained at Tharandt. Under the influence of this training, an attempt was made to adopt clear cutting methods, to regularize the forests and simplify management, but after a half century of practice the re- sults of clear cutting in the Alps and in the Jura were far from satisfactory. Consequently, the selection method of felling has now been almost uniformly adopted, especially through the teach- ing of Professor Engler. The type of selection cutting is what the writer calls a system of concentrated selection fellings with a long period for regeneration either by single trees or by groups, with a cutting cycle of ten years. In Canton of Vaud, for ex- ample, it is interesting to learn that even in an ordinary high forest if a private owner wishes to cut more than twenty cubic meters of wood, he must be authorized by a representative of the state. In protection forests not a single tree can be cut without the approval of federal officials. By a law passed in 1914, except under the most unusual circumstances, clear cutting in protection forests is absolutely forbidden. T. S.

The depth to which the soil is open Soil enough to allow the penetration of tree Physiology. roots does not always determine the dis- tance the roots descend. In other words, the absolute soil depth and the physiologic soil depth are not necessarily equal. It is only the moist, crumbled, well aerated soil which contains a high percentage of the organic matter that supports root growth. A compact, sticky soil and a too open sandy soil without humus alike prevent root growth. The distribution of the soil water is a most important factor. Trees require a large amount of water, but also the drainage must be good. In fact, xerophytic plant formations are found on sandy soils under which the water table is high because it is only the top layer of soil which is well enough aerated, and that drys out rapidly on account of its sandy character. The following table shows the relation of soil depth to site quality for pine: Periodical Literature. 269 Quality. Depth. Geometric mean.

Much can, however, be done by cheaper methods of cultivation prior to reproduction ; provid- ing there is a proper mixture of deep and shallow rooted species, so as to completely utilize the soil and prevent its deterioration through weed growth, excessive light, and loss of humus. In the application of such methods the three main objects to be at- tained are drainage, complete aeration and the maximum humus content. The following table shows the comparative cost of different methods of cultivation prior to securing natural regeneration or planting : Ridge cultivation, (especially applicable to swampy soils and sandy soils with a high water table, $20 an acre Deep plowing (over 12 inches), $8-10 an acre Shallow plowing, $4 an acre Dynamiting, $16 an acre K.

It is a common practice of the profession Soil in Germany to have excursions which visit Preparation points of interest and take up, under the for guidance of the responsible officials the Natural problems of management which the forest Regeneration. visited presents. While it will be several generations before we can show the results of long time management, the excursion idea is a good one. It profits both the visitor and the visited. The most interesting points about the Langenbrand Forest in 270 Forestry Quarterly. southwest Germany is the method of soil preparation employed to secure natural regeneration. The forest now has the following composition: Fir, 63%; Spruce, 14% ; Pine, 17% ; Hardwoods, 60%, (mostly beech). The problem is to secure natural regener- ation of the desirable softwoods without opening up the stand too much, drying out the soil and encouraging weed growth. Still the thinning must be severe enough to afford the relatively intolerant spruce and pine an advantage over the tolerant beech and fir. Good results have been obtained over 280 acres in the period 1907-1913 by digging up the ground to a depth of 15 inches in spots about 2 feet square. The moss and weeds are en- tirely removed in these spots and the mineral soil thereby ex- posed. Success was attained over 93% of the area regenerated in the period from 1905-1913. Another interesting point in the management of this forest is the recent reduction of the rotation from 120 to 100 years. This has resulted in an increased total yield with a smaller percent- age of thinnings. The present yield is about 10 cu. ft. per acre, 25% of which comes from thinnings. At this time the distribution of age classes is as follows : 1-20 years 11% 21-40 years 20% 41-60 years 11% 61-80 years 13% 81-100 years 29% Over 100 years 16% K. W. W.

Okliabin, describes the Interception results of his observations conducted at Crowns one of the forest experiment stations in In Russia (in the province of Samara) upon Pine Forest. the amount of precipitation that penetrates through the crowns of a pine forest from 80 to 100 years old and having a density of from 0.6 to 0.7. Twelve rain gauges were installed on an area of about 1,000 square meters under the crowns of the trees and in the spaces between the tree crowns. In addition to these rain gauges there Periodical Literature. 271 were three other rain gauges, of which one was placed under the crowns of the trees on a tower, another in a small opening, and a third under the crowns. Measurements of rainfall by means of all these rain gauges were carried on from December 15, 1904, until October i, 1909. The most essential results obtained by the author are as fol- lows : (i) Precipitation in the form of rain is intercepted by the crowns of trees to a larger extent than in the form of snow. In the case of rain the average amount intercepted is 28 per cent., in the case of snow 12 per cent. (2) The lighter the precipitation the more of it remains on the crowns. Thus the amount intercepted, on an average, in the case of rains from o.i to 1.9 mm is 41 per cent ; 2.1 to 4. 9 mm is 36 per cent; 5.0 to 9.9 mm is 19 per cent. In the case of snowfall a similar dependence is observed, but it is less pronounced, since the snow intercepted by the branches is gradually blown down into the rain gauges. R. Z. Lesnoy Journal, 1913, No. 5- Water Lost In order to establish a relation between by the evaporation that takes place from an Pine Trees evaporometer and the loss of water by a and three-year-old Scotch pine, parallel obser- Evaporometers. vations were conducted by A. P. Tolsky during the summer of 191 1 at the Forest Experiment Station in the Province of Samara, at 7 a. m., i p. m. and 9 p. m. The pine was planted the year before in a zinc vessel with soil. The loss of water was determined by weigh- ing. The amount of water lost was replenished by means of a tube that reached through the lid covering the vessel to the bot- tom. The lid closed the vessel hermetically and had in addition to the opening through which the tube was inserted only one other opening for the stem of the pine. By watering, the level of the water in the soil was- maintained at the same level through- out the entire experiment. From the results of these observations the author came to the conclusion that the loss of water by pine : (i) Depends, just as in the case of the evaporometer, upon the temperature, solar radiation, humidity of the air, and the velocity 272 Forestry Quarterly. of the wind. It was impossible to establish this relation during the entire vegetative period, since, in order to do that, much shorter intervals were required. (2) During the period of development of young shoots, the loss of water in the pine does not go on parallel with the loss of water from the evaporometer, especially in May and June. This would indicate that physiological processes have more to do with the loss of water from plants than meterological conditions. (3) During the day, the greatest loss of water by the pine was observed in the morning and the forenoon hours. The evaporometer lost most water in the afternoon hours. (4) The ratio between the loss of water by the pine and that by the evaporometer is especially great during the months of May and June. This period coincides with the vigorous growth of young shoots and needles. (5) By comparing the loss of water from the pine with that from the evaporometer for definite periods of time, it is possible to determine converting co-efificients by means of which the in- tensity of physiological activity of plants for different periods of their development can be ascertained from the records of the evaporometer.

Periodical Literature. 273 Without cover, the soil at times lost its entire moisture avail- able for plant growth. Albert sees the effect of the cover not only upon the moisture contents of the soil, but also upon a num- ber of other factors' and, for this reason, he believes that by cov- ering the ground it will become possible to eliminate the failures in the reforestation work in sandy soils.

The results show that the first two yield approximately equal money returns, whereas the last named lags far behind. The volume increment is greatest with (i), least with (2), and intermediate with (3). Many interesting figures are developed, in tabular form, and the author reaches the justifiable conclusion that the static (com- parison of values) of thinnings requires just as exact a division into grades of timber secured as does that of the final yield.

The investi- Scotch Pine. gation was made on the State Forest of Kunersdorf near Schandau. It was begun in 1862 when the stand was 20 years old and was ended in 1912, when the stand was 70 years old. During these 50 years three comparative areas were thinned ten times, to wit: in the years 274 Forestry Quarterly. 1862, 1869, 1874, 1879, 1883, 1889, 1894, 1900, 1905 and 1912, one area always with a light (A-grade) thinning, another with a moderate (B-grade) thinning, and the third with a heavy (C- grade) thinning. The results show that the heavy thinning in no way retards the height growth, that it, in fact, reacts favorably thereon. Most interesting is the comparison of the volume increment of the three areas. Total final yields of A grade thinningr=7,693 cu. ft. per acre. Total final yields of B grade thinning=8,i65 cu. ft. per acre. Total final yields of C grade thinning=9,438 cu. ft. per acre or an increase of 22.7% over A grade and 15.6% over the B grade area. Another important result is that the heavy thinning does not bring about a lessened clear-length (lower crowns) but, on the contrary, an increased clear-length commensurate with the greater height growth. Regarding the form of the bole, Dr. Kunze, the investigator, himself says: "The experiments by no means justify the assump- tion that heavy thinning of Scotch pine means poor form of the stems," The volume increment is greatly stimulated by the heavy thin- ning; the exact figures are not given in Dr. Weber's review. (The results are published by Paul Parey, Berlin and sold at 38c a copy.) All in all, concludes the reviewer, these results coincide with similar experiments elsewhere and are an additional argument in favor of heavier thinnings. A. B. R. Mitteilungen aus der Kgl.

This advantage in volume accrues when the proportion of pine is 50% and over. A. B. R. Zur Fragc der Mischehcstandc. Allgemeine Forst- und Jagd- Zeitung, March, 1914, pp. 90-93 (see also p. 109). Forstmeister von Gabnay brings together Damage the latest information regarding the in- by fiuence of asphalt or other tar coverings on Tar. trees. He first points out that the tarring of trees against insects produces the death of the cambium layer and, if the bark has been removed near to the wood, of several layers of sap wood, which may after- ward be overgrown, but leave a defect that can never be cured. A number of Frenchmen were first in the field investigating the influence of asphalting roads, but the most extensive investi- gation is that of Professor P. Claussen, who reports in the Pro- ceedings of the Imperial Biological Institute for Agriculture and Forestry (Vienna). These investigations show that there is a great deal of diflFerence in the tar used, some of the manufactures being poisonous and others not.

The dust arising from tar coverings is also damaging, especially on young leaves. Some plants lose their foliage, in others the leaves remain small, become red, or red spots develop, or they even develop specially protective tissue. The author recommends to be careful in the choice of tars, not to tar the road in its entire breadth, but leave a strip along the row of trees, so as to keep bole and root system free, and to choose trees which are more resistant to this kind of damage.

Tol- Weather sky at the forest experiment station in the and Province of Samara upon the progress of Height Growth. the development of plantations and their growth in height led him to the following conclusions : d) The growth in height of young shoots of Scotch pine in southeastern European Russia takes place during the months of May and June ; the growth of the pine needles in July and Aug- ust. This phenomenon has been annually confirmed by observa- tions extended for four years, between 1908 and 1912. 2/8 Forestry Quarterly. (2) There is no gradual, uniform development of the shoots. The growth of the shoots varies in accordance with the condi- tion of the weather. During cold nights in May the growth often stops entirely. In June, because of the warmer weather, the growth during the night exceeds that during the day, whereas in May the growth during the day is greater than that during the night. (3) The length of the annual shoots is influenced by the weather conditions of the year before, especially during July and August, when buds are formed. If the weather during these months is warm and humid, the growth of the next year is much greater than if the weather was cold and dry. These ob- servations confirm the investigations conducted by Professor Cies- lar in Austria and by Forester Turmer in Russia upon the growth of spruce. (4) Unfavorable weather conditions during early spring, i. e. in April and May, for instance, low temperature, late disappear- ance of snow and a large number of late frosts — or the reverse, abnormally high temperature during the spring — may affect more or less considerably the growth of the year. (5) Weather conditions during the further growth of the young shoots influence directly only the degree of development of the needles. The latter, just as in other herbaceous vegetation, de- pends most intimately upon the actual condition of the weather, that is, upon temperature and humidity. Moderate temperature and humid weather increase the length of the needles. Reverse conditions decrease it. The weather conditions, however, dur- ing the growth of the young shoots have only a secondary effect as compared with the influence which the weather of the previous year has upon them. R. Z.

Dr. Speidel of Stuttgart considered that such funds could best be created by setting apart a portion of the income from the sale of excess growing stock or of enforced cuttings (storm, fire, etc.). The general discussion seemed to favor timber re- serve funds rather than tnoney reserve funds. A. B. R. Die XXI Tagung des Deufschcn Forstzvirtschaftsrates in Trier, 1913.

The reviewer is reminded of Strazeleckis' proposal* to calculate the normal growing stock by the formula : nV= — I Jl -f- -— ''I where r=rotation age; £ ^volume at ^ the rotation age; 2 Vr=volume at the rotation age. Baader would regulate the yield, both final and intermediate, by increment alone but this, the reviewer contends, is an insuffi- cient basis: first, because of a lack of exact data — especially in the case of intermediate yield (thinnings) ; secondly, because val- ues as well as volumes enter into yield determination ; finally be- *Allgeineine Forst- und Jagd- Zeitung, 1884, p. 88, p. 316. 28o Forestry Quarterly. cause these are always conditions of ownership and utilization which make a mere determination by volume based on increment inexpedient. For all these reasons area as well as volume must continue to play an important role in yield determination, espe- cially in all intermediate yields. The reviewer concludes that the proposal to abandon all area control is rather previous and would increase the cost of control and administration without any corresponding advantages over present methods. He, however, commends Baader's dissertation as clai*ifying the subject of increment determination and as stimu- lating more exact work along these lines. A. B. R.

A unique and extensive detailed report Evaluating is furnished by Oberforstrat Reus on the Damage damage occasioned by the drought of 191 1 /row over the entire forest property of the Duke- Drought. dom of Anhalt, comprising around 75,000 acres in very varied condition. In the year 191 1, precipitation was deficient by about 37 per cent, of the nor- mal ; this, after a year, of ten per cent, below normal. The total loss in money is figured at around $100,000, or $1.35 per acre of the total area. In this calculation, there is included a reduction in value on the forced cut which was found to be on the aver- age 2/3 cent per cubic foot, a reduction in the productivity of stands due to the killing of timber of $30,000 and in the cost value of destroyed cultures and young stands of $65,000. To re- cover the damage in the plantations, some $35,000 will be re- quired. The total cut of dead material necessitated by this drought was 840,000 cubic feet timberwood, or something like 12 cubic feet timberwood per acre. The territory of the Harz Mountains suffered the most. Here the cut was nearly 30 cubic feet per acre. The acreage of young stands under 20 years which was entirely destroyed was around 1,250 acres, or about 2| per cent, of the total forest area. Among the observations of the difference of damage under different conditions the following are of interest. Of pine plan- tations, 20 per cent, were lost, while of pine sowings 40 per Periodical Literature. 281 cent, were killed, showing the plantations to have borne the drought better than the sowings, made in both cases in furrows. In the oak cultures, sowings showed very little loss ; plantings of small stock 12 per cent. ; plantings of saplings 30 per cent. Here, however, the good sites involved explain the small loss in the sowings. In pine stands underplanted with spruce, 50 per cent, were lost. The underplanted spruce in oak, beech and larch in the Harz Mountains was entirely lost. Beech of natural re- generation was lost to the extent of 22 per cent. ; but stands over 20 years of age did not suffer much. On grassy soils the cultures suffered considerably more than on open soil, even in sandy situations. As regards mixed stands, spruce in the Harz Mountains suffered more in the mixed than in pure stands, especially in the deciduous mixture. Spruce with oak suffered more than with beech, the lower stem classes particularly. When mixed in single individuals the loss was less than when in groups. Evidently the shallow-rooted spruce could secure less moisture from the soil than the deeper-rooted deciduous' trees. In mixed stands of pine with beech and oak no difference appeared, when compared with pure stands. The resistance to drought of different species was found on the whole to depend upon the depth of root system. The series being beech, pine, oak, alder, birch and aspen, spruce. In cul- tures, however, the series is somewhat different, namely oak, spruce, pine, birch and alder. As regards the influence of depth of soil, even the young stands suffered less on deep soil than on the shallower soils. As re- gards exposure, apparently not much difference was found, the loss on the plateau being 5 per cent., north and south exposures 9 per cent., south and west exposures 8 per cent. As regards site classes, the better the more resistant were the stands shown to be. As regards age classes, naturally the younger stands showed the largest loss, the 1-20 age class showing a loss of 8^ per cent., the age classes from 21 to 80 years between one and i.i to i^ per cent., the older age classes showing a slight fraction. As a consequence of the larger amount of dead material, insect pests began to develop rapidly, but the immediate utilization of the dead material and pulling out of the young damaged growth, and other thorough methods of combating the pests have prevented 10 282 Forestry Quarterly. additional loss. It was found that a dry rot as a secondary re- sult had attacked to a large extent the roots of spruce and deciduous trees, but the fear that this would lead to a consider- able further loss seems so far not to have been realized. It is supposed that such a drought had not occurred within the last 150 years, and therefore the damage is considered most un- usual. Die Durresschdden z'on igii in den Anhaltischcn Staatsforsten.

In the latter coun- Insurance. try a mutual fire insurance company was organized in 191 1, to which we referred in volume XI, p. 525. There is now the first report of this society at hand. Norway possesses about 23,000 square miles of productive forest area, of which something over 61 per cent, is coniferous. Of this 85 per cent, is owned privately. The total forest value is estimated at 160 million dollars, or about $12.50 per acre. There are strict laws and for most districts good organization to combat forest fires, with all modern methods of look-out sta- tions, telephones, telescopes, maps, etc. During the extraordinarily dry year of 191 1, after a number of disastrous conflagrations, 50 of the largest private forest owners, owning altogether nearly 500,000 acres, of the value of around 5 million dollars, associated themselves for mutual pro- tection, and by September, 1913, 1,372,000 acres, or 10 per cent, of the forest area in the districts, valued at $9,000,000 were in- sured, with the expectation of bringing up the insured values to $20,000,000 by the end of the year. The premium paid on acreage to the end of September was over $16,000 or 1.3 per cent, of the insured values or 12 cents per acre. Only $72 dam- age were paid out, and it was therefore possible to place $112,000 in reserve. The insurance is made only on young plantations and on the forest soil, which are representing the most vulnerable part, since matured stands suffer little, and since these are relatively high in value and the premiums which would have to be paid would be Periodical Literature. 283 relatively disadvantageous. The owner himself is obliged to state the value of his forest, as well as of the damage, if any, the as- sociation reserving the right to review both. The association pays all damage, no matter what the cause of the fire. Usually the insured has to insure his entire property, and the agreement is made for at least five years. No damage is paid unless at least 2| acres are involved. Premiums are paid for the year in advance, and an additional premium up to treble the original may, if necessary, be levied. At present forests in the districts with satisfactory laws against forest fires are taxed i;^ per cent., unless the forest is located in a zone of special danger (e. g. in the neighborhood of towns), when if per cent, is levied, the same as in other districts not well provided against fire. No special consideration is made as regards railroads passing through forest country, since the railroad companies are liable. It is expected that as the number of insured grows smaller premiums will suffice. Die Waldversicherung in Norwegen. Schweizerische Zeitschrift fiir Forstwesen, January, 1914, pp. 21-24. UTILIZATION, MARKET AND TECHNOLOGY. Professor Jaccard has published the re- Failure of suits of his investigations into the char- Wood in acter of the failure in compression parallel Compression. to the grain. His first studies were with specimens ruptured in a testing machine ; later he included natural failures such as are found at the base of limbs, in crotches, and other places on trees where as a result of growth the fibers were subjected to stress great enough to cause failure. He finds that there does not exist a specific type of rupture, i. e. one that is characteristic of every ligneous species, and that test blocks taken from the same kind of wood or even from the same log, may show on their homologous faces lines of rupture of little similarity. On the other hand when the test blocks are taken from woods that are of similar structure though of differ- ent species the lines of rupture of homologous faces may exhibit great resemblance. This is due to the fact that the resistance of the fibers is influenced in an analogous manner by the size, num- 284 Forestry Quarterly. ber and distribution of the vessels which accompany them, or in the case of the conifers by the particular structure of the early wood of the growth rings; in other words by the distribution of the elements of unequal resistance in the body of the wood. The shortening of a block in compression is obtained either by the transverse bending of the fibers with a formation of a swell- ing of rupture, or by curvature of the fibers with the bulging of one or more of the faces of the test block. Among conifers and in a general way among the ligneous species with a fine texture and homogeneous structure the first type is commonly met with. In addition to the anatomical structure the degree of humidity of the wood has an influence on the mode of rupture, fresh or green wood behaving quite dififerently from that which is air- seasoned or kiln-dried. The author refers to the experiments made by the U. S. Forest Service as recorded in the appendix of bulletin 70 and states that his own observations are in com- plete accord with Tiemann's. It is Jaccard's contention that the direction of rupture is not influenced by the distribution of the medullary rays, which simply curve with the bundles of fibers to which they are attached. When the compression is continued until failure results, the rupture is in the form of longitudinal rents through the fibrous mass aflfecting equally the rays, the elements of which break in the median plane and not along the plane of attachment to the wood fibers. In fact it is very rare to observe a true detachment of the walls along the middle lamella. The folding of the fibers or of the tracheids is accompanied by characteristic alterations of their walls. The latter seem to split into thin lamellae or sheets. Under high magnification the walls of the tracheids cut longitudinally present a fibrile or thread-like structure without definite arrangement, while on cross section numerous concentric strata are visible. The author con- cludes that the successive strata of growth of the fiber wall al- ternate with planes of less cohesion which under the compressive stress separate by shear or cleavage. As previously shown by Tiemann the folding of the tracheids may be materially influenced by the bordered pits which form weak places in the wall. Sometimes the pit is crushed and again only deformed. In test blocks of certain broad leaf species such as Platanus Periodical Literature. 285 and Gleditsia longitudinal rents often appear and separate bun- dles of fibers. These splits do not occur along the rays nor even along the large vessels which run through the mass of the wood, but within the bundles of wood fibers' themselves. The rays in the course of the rents are torn like the other elements, but those imprisoned in the interior of the bundles are merely bent. Ex- cept in the case of complete failure the lumen of the folded ele- ments usually remains open, not only in the case of ligneous fibers with thick walls, but also in the vessels. The author's studies of the natural failure of wood bears out his conclusions from the test specimens. His main point is that the distribution of the rays has little eflfect upon the mode of failure. This is not in accord with the findings of M. Thil who says: The sides of the medullary rays sometimes produce planes of least resistance varying in size with the height of the rays. The rays assume a direction more or less parallel to the lumen of the cells on which they border, the latter curving to the right or left to make room for the ray and then closing again beyond it. If the stress acts parallel to the axis of growth, the tracheids are more likely to be displaced if the marginal ray cells are weak- walled. It is on that account that on a radial section of the test •block the plane of rupture passes in a direction nearly that of a ray, whereas on a tangential section the direction of the plane of rupture is oblique, but with an obliquity varying with the species and determined by the inclination of the spirals on which the rays are distributed in the stem. — Constitution anatomique dii hois, pp. 140-141.

STATISTICS AND HISTORY. Early reports on forest administration Early in the northwest province and in Oudh Administration throw an interesting light upon the crudity in India. of the administration as it then was. An officer in charge of an important forest wrote in 1872 that he had spent $10 in protecting his forest from fire, without avail. A novel method of sale was' then in force, namely, to charge $1.00 to $1.60 per month per cart rather than a rate per unit of product. Students of forest history should not fail to read this article. T. S. W., Jr. Indian Forester, March, 1914, pp. 75-94. In connection with the expected re- Smiss vision of import tariffs, a very careful in- Statistics. vestigation into forest supply conditions of Switzerland is being made by a special commission, of which Professor Decoppet is chairman. Switzer- land comprises 16,000 square miles, with a population of 3,- 750,000. Its forest area is 2,141,000 acres. The Commission finds the total production of wood as 95 million cubic feet, 44 per cent, of which is workwood, and 56 per cent, fuelwood. The consumption, however, is 120 million cubic feet, distributed between workwood and fuelwood in equal proportion, 90 per cent, of the workwood being coniferous. The total value of the manufactured lumber reaches $11,000,000, at 23.8 cents per cubic foot, which makes the value per M feet B. 'M. in the neighbor- hood of $20. In the 26 years from 1885 to 191 2, a very considerable in- Periodical Literature. 287 crease in quantities and values of imports' has taken place, the importation in quantity having trebled, in value quadrupled. While as to values, wood importations as a whole have increased 170 per cent, that of workwood alone has increased 500 per cent., lumber in particular 328 per cent, and woodenware 200 per cent. While Germany in 1885 furnished 66 per cent, of the total wood import (2.4 million dollars), in 191 1 it had dropped to 33 per cent. On the other hand, Austria rose from 8 per cent to 44 per cent, with $4,000,000. France's contribution rose from $600,000 to $1,000,000. Scandinavia, Russia, and America, which in 1885 were almost not at all represented, have risen to 1.4 mil- lion dollars. Exports, while during this period falling in quantity to one-half, in value remained about equal. Striking a balance, in production and consumption it is found that the deficit which in 1885 was $200,000, in 191 1 had risen to $8,200,000. The conclusion is reached that it would be undesirable to have a tariflf for protective purposes, on fuel wood. If the tariff on fuelwood were increased, prices would rise for the moment, but would soon go back to their former level, as' the consumption of wood w^uld decrease. As regards the deficit of 22,000,000 cubic feet of workwood (230 million feet B. M.), it is pointed out that the attitude of the tariff should be to encourage the im- portation of unmanufactured material, and discourage that of lumber. The importation of raw material increased during the 26-year period by 500 per cent. Experience has shown that the tariff for lumber should be at least 6 times that for round material, the difference representing the loss in labor value. We may only add the conclusions, regarding the tariff question. "Duties' on wood permit an equalization between domestic and foreign production, which latter often works more cheaply, and may be able to calculate with lower transportation costs, but the net yield of the forest is not influenced to the extent, which it is often assumed, by import duties, for wood prices depend on other factors which exercise greater influence than tariffs. In- deed, the increase in duties in the years 1885, 1898, and 1906, did not have as a result a decrease of imports, but a very lively market shortly before the new tariff came into action, then was followed by a reduction in imports during the using up of the ac- cumulated stores, and then the importation continued in the even 288 Forestry Quarterly. increase of the former time. The yearly natural differences in imports are often larger than those occasioned by new tariffs. The periods of increased importation are, as a rule, also periods of increased market for the producer. Increase in population and general prosperity occasion the increased use and increased im- portation. Die Vorarheiten ztir Brnexirung der Zolltarifc und Handclsvcrtr'dge. Kategorie Hols .

They show that on January i, 191 2, the total area of state forests comprised i, 449, 310 acres. Since 1878 the an- nual cut has increased from 45 cubic feet per acre to 107 cubic feet per acre in 191 1. This rise is due in part, to increased ac- cessibility and better markets, but also to frequent revisions of the working plans which showed a larger growing stock and in- crement. Furthermore, the change from pure beech stands to mixed stands and the afforestation with spruce and fir has brought about an increased yield. Finally the increase is due, in no small measure, to a more intensive silviculture. The net yield in 191 1 was $8.14 per acre. In the S3 years since 1878 the income from thinnings has been between 20 cents and 35 cents per acre for the total area. The cost of planting, in 191 1, was twenty-two and two-fifth cents per acre; the cost of road building fifty and two-fifth cents per acre. A. B. R.

In accordance with Forestry the usual custom, the executive committee Congress. met in advance and prepared the program for the session of the Congress. The first business of the general meeting was the presentation of a paper on "Border cuttings," by Doctor Wagner of Tubingen. No important points not already covered by previous reviews were brought out in the paper or the discussion that followed, so that a mere allusion is sufficient. The findings of the Committee on Pine Seed may be summar- ized in the injunction to use only local seed from the best in- dividuals of the species, and in the recommendation to insure seed inspection. The committee which investigated timber trade conditions re- ported the need of securing greater publicity in timber sales, in order to obtain better prices. Some regular method was recom- mended for this kind of advertising, and also for the dissemina- tion among the profession of information in regard to the prices being secured, which must be accurate and timely to be of value. Tariff conditions were the subject of a report by a special com- mittee, and also worked considerable discussion in the general ses- sions of the Congress. Agreement was finally reached on several fundamental principles and desirable points for legislation. Since Other Periodical Literature. 291 the Congress was unanimously in favor of protection for the business of timber raising, these recommendations covered merely the ways in which protection should be given. In general, the purpose was to protect the lower grades of wood products from competition, because of the necessity of furnishing a local market for such material. The tropical hardwoods and other species' which supply needs not to be filled by native woods would re- quire no tariff. In the case of pine cones to be used for seed extraction, it was recommended that the import duties be made prohibitive, in order to insure the use of local seeds for reforesta- tion. The Comrnittee on propaganda recommended activity along the following lines : Co-operation between state and national forestry associations ; collection of economic and technical data ; student trips through the forests; press notices; local meetings. The question of reserve funds was discussed at length apropos of the recent legislation in Wurttemburg. While a small forest unit needs to make no distinction in the distribution of such funds, the large state forests require separate funds for cutting, improvements, and to produce normal stocking. The cut- ting fund provides for carrying on the harvesting operations. The second division covers the cost of road building, telephones, and buildings. The fund for stocking is a form of insurance against the accidents, like windfall and insects, which disturb the normal condition of a forest. K. W. W.

These men not only investigate fires which may occur, for the purpose of collecting information to be used in claims cases, but, what is more important, they help to prevent the occurrence and spread of fire by personally meeting section-men and other regular employees of the Company and making sure that the men are fully informed regarding the very strict instructions issued by the General Manager relative to the reporting and extinguishing, by railway employees, of fires occurring along rights of way. These inspectors also assist the Operating Department in securing efficient action in connection with the requirements of the Rail- way Commission relative to the maintenance of special patrols in forest sections, and the removal of inflammable debris from the Company's right of way. Under this method of organization, much better results are to be anticipated than was previously the case. The spread of the co-operative idea in forest fire protection is evidenced by the recent organization of the Lower Ottawa For- est Protective Association, Ltd. This Association represents nearly 10,000 square miles or over six and a quarter million acres of timber lands on the watersheds of the Gatineau, Lievre, Rouge, Coulonge, Nation and Devils rivers in the province of Quebec, l^e staflf will comprise a manager, three inspectors and about 50 rangers. The headquarters of the Association will be at Ottawa. In order to co-ordinate the efiforts of all the agencies interested in protecting this region from fire, the manager of the Association has been appointed an officer of the Forest Protection Branch of Quebec, as well as of the Fire Inspection Department of the Dominion Railway Commission. A close co-operation with the settlers and with the railways operating in this territory is also proposed, in order to reduce the fire hazard as much as possible. News and Notes. 295 The latest Canadian railway to organize especially for the more efficient handling of fire protection work is the Algoma Central and Hudson Bay Railway. This line taps a heavily timbered sec- tion in Central Ontario, extending north from Sault Ste. Marie. D. C. A. Galarneau has been appointed forester to the Company, with duties which will include supervision of railway fire pro- tection. The lowest level of forest fire loss on record in Canada was reached this year on Dominion Forest Reserves in Western Can- ada. On the reserves in British Columbia, not a single fire suc- ceeded in spreading over a larger area than 10 acres. The re- cords are not yet complete for Saskatchewan and Manitoba, but the available figures compare favorably with those for the re- serves farther West. All the figures compare favorably with corresponding ones for the National Forests of the United States where the area burned in 1913, although the smallest in recent years, was somewhat over 0.03 per cent, of the total reserved area. In the Fire Districts on Dominion Crown Lands in the west patrolled by Dominion fire rangers the loss occasioned by forest fires last season is also remarkably small, not due entirely to the large amount of rain which fell last summer in the West. In the Coast Fire Ranging District, B. C, which being situated in the Railway Belt is administered by the Dominion Forestry Branch, during June, July and August no less than tio fires occurred, yet all of these fires were extinguished by the fire- rangers before any standing timber was destroyed. That the fire loss in the West has been so remarkably small is due in large measure to the fact that the Government rangers un- ceasingly sought, and obtained, the co-operation of all with whom they came in contact, whether settler, Indian, hunter, tourist or packer. During 1913 the forces on the National Forests fought 4,520 fires or nearly twice as many as started in 1912. In both years, practically 50 per cent, of all fires were detected and extinguished before they burned over a quarter of an acre, and 25 per cent, were put out before they covered 10 acres. In only 25 fires did the damage amount to $1,000. The aggregate loss in timber and 296 Forestry Quarterly. the damage to young growth and forage is estimated at about $192,000, the timber loss, nearly 59 milhon board feet, being valued at $82,000. About 18 per cent, of this total loss was in- curred on private lands, within forests where 16 per cent, of the fires had their origin. Reports for the winter fire season in the southern Appalachians, from southern Virginia to northern Georgia, covering the months of January and February, just received by the Forest Service show that the winter was dry and that fires have occurred on land which the Government is acquiring under the provisions of the Weeks Law. While these two months are normally not so dry as the fall or the spring fire season, serious fires may occur in an open winter, though they are not usual. During January there were 9 fires, 5 of which covered more than 10 acres each. In February there were 10, of which only two spread over more than 10 acres. All of these fires occurred during the latter part of January and the first of February when the weather was unusually dry. According to a press bulletin of the Forest Service, lightning next to railroads is the most frequent source of forest fires and the most numerous species in any locality is the one most likely to sufifer. It is probable that most of the fires from lightning start in the duiT at the foot of the tree. Especially in the South- west, it is stated, "dry thunder storms" increase the danger. The Cornmissioner of Dominion Parks Branch furnishes an in- novation of fire notices by printing them on enameled tin sheets, which are practically indestructible. An exceedingly clear im- print is possible. The cost may be considerably more than linen, but the durability and consequent saving in renewals may offset this greater initial cost. During the first three years of its administration, from 1905-7, the problem of the U. S. Forest Service was to take care of areas which had been badly overgrazed, and a material reduction had to be made in the number of stock grazed before the damage could be stopped. From the very beginning, the Forest Service invited the co-operation of the stockmen, and consulted with News and Notes. 297 them regarding the practicability of the plans which were to be adopted. This co-operation was secured ■ through the various stockgrowers' associations, and it has proved so successful that similar associations have grown up among other users of the National Forests, Before range control was put into effect, the feed belonged to the man who got his stock on the land first, though there was no way by which he could hold it except by physical force. Such a system proclaimed that might was right, and led to controver- sies, and later to range wars. Under the present control, right prevails, and such an achievement alone would have made the work worth while. The systematic use of the ranges has stopped loss of forage, and feed formerly wasted has been putting the stock in better condition. Experiments of the Government in artificially reseeding the grazing areas to cultivated grasses show that in some cases the forage crop has been increased as much as 400 per cent., but this method is both slow and expensive, and it has been found that a great part of the range lands must be improved by protec- tion and natural reseeding, for the next 20 years at least. In- vestigations have established beyond a doubt that natural re- seeding can be accomplished best by a rotation system of graz- ing, based upon the simple principle that grazing aids in scattering: and planting the seed after the seed has been given an opportunity to mature. Reports show that areas protected until after seed maturity and then grazed, as compared with areas absolutely protected for the whole year against grazing, are approximately 50 per cent, better, and probably 200 per cent, better than range which has not been protected at all. This means that ranges can be improved faster in use than they can be in idleness, and this principle is being adopted on many of the Forests. In the "free for all' period of early days, the most palatable forage plants were so closely cropped that they were unable to develop the necessary plant food, and so literally starved. Also, the roots were frequently injured by trampling, or killed by ex- posure. As a result, the best kinds of vegetation grew weaker from season to season, and where the practice of early and close grazing was continued, the range at last became practically de- nuded. 298 Forestry Quarterly. The remedy suggested for range deterioration is a system of deferred grazing. Under such a plan, an overgrazed portion of the range, sufficiently large to supply the forage from the time of seed maturity until the end of the grazing season, is protected from stock until the seed crop has matured. Upon maturity of the seed crop the forage is grazed during the first season, but not to the extent of injuring seed plants. The same area is protected in the same way during subsequent seasons until the new plants have been securely established. When the area has been thor- oughly reseeded it can be again grazed early in the season, and a second area is protected until the forage is mature. By this method of alternating late grazing from one area to another, weakened vegetation can recover its vitality without the need of having the land closed to grazing the entire year. The new open system of handling sheep, which is quieter herd- ing during the day and bedding the sheep where night overtakes them, is in contrast to the old plan of herding them close by the use of dogs and returning them each night to a fixed bed Iground, an improvement. The old plan, of course, rendered cer- tain areas absolutely bare and the going from and returning to the bed grounds trampled a great deal of forage. He estimates that an increase of 10 to 25 per cent, has been added to the carry- ing capacity of the ranges and that 5 pounds weight has been added per lamb, because they have not been harassed by herding or forced to trail long distances to and from bed grounds. One objection to the new method of handling sheep brought up by many owners has been that the herders who were used to the close system would not adopt the new one, for herders na- turally take a pride in having their sheep look well, and, since they are coming to realize that open herding means better sheep, they voluntarily adopt it. Grazing permits on the National Forests have been issued for nearly 11 million animals, including nearly 2 million head of cattle and horses, nearly 9 million head of sheep and goats, and about 65 thousand hogs. This means an increase for the current year of about 38 thousand more cattle and horses, and 347 thou- sand more sheep and goats, although the gross area of the Na- tional Forests at the beginning of 1914 is almost a million acres less than at the beginning of 191 3. News and Notes. 299 During 1913, according to the reports just compiled, more than 2y thousand stockmen paid the government for grazing per- mits on the National Forests. For several years past the carrying capacity of the National Forest ranges has been slowly rising, which, forest officers say, indicates an improvement in general grazing conditions and a better utilization of the forage resources. They claim that this is due mainly to the enforcement of better methods of distribu- ting and handling stock. On the lands recently acquired by the federal government within the Appalachian region of the East, regulated grazing has also been introduced this year on six distinct areas. The next Canadian Forestry Convention will be held at Hali- fax, N. S., September i to 4, 1914. This will be the first Canadian forestry convention ever held in Nova Scotia. On May 15 a large audience assembled at Cornell University to celebrate the opening of the Forestry Building of the New York State College of Agriculture. Three sessions were held with addresses by prominent men interested in the forestry move- ment, the afternoon being specially devoted to forecasts of progress for the next decade. The evening session had to be adjourned to the large Auditorium to accommodate the crowd who had come to listen to the poetic effusion of former Director L. H. Bailey and to Mr. GiiTord Pinchot's address on the movement for con- servation. The following morning the Society of American Foresters held its first open meeting outside of Washington, and both the attend- ance and spirit of the meeting fully justified this departure. Be- sides some 30 active members of the Society, a large contingent of associate members and of forestry students filled the hall. The latter came from various forest schools as delegates of their for- est clubs with a view of forming an association of these clubs, which was effected. The open meeting was preceded by an executive meeting to discuss action on the questions lately submitted to the member- ship by letter ballot and on other questions. The following resolution, offered by W. B. Greeley, was adopted : 300 Forestry Quarterly. That tht Society of American Foresters shall investigate scientific problems through its own membership and resources, or in collaboration with other agencies. That the results of such investigations shall be placed before the entire membership of the Society by publication in its Proceedings, or other- wise; and a ballot obtained thereon when advisable in the judgment of the officers or committees in charge of the investigations. That the results of investigations may be published for general distri- bution, in the discretion of the officers or committees in charge of them, either as the conclusions of the members or committees conducting the investigations, or with a statement of the vote of the Society thereon when deemed advisable. That the Society shall not officially endorse conclusions as to scientific facts ; but may, with the concurrence of two-thirds of the members bal- loting, take an official position upon matters of policy. The policy of holding at least one meeting annually outside of Washington was endorsed. Efiforts shall be made to organize local sections and to affiliate local organizations with the Society. Committees shall be appointed to take up questions of nomen- clature and terminology, the standardization of scientific methods, and the bringing together of information regarding investigative projects. Among the speakers at the open meeting Mr. Gaskill outlined the effort which should be made in the next decade in State For- estry in the East; Prof. Roth presented his views on the outlook in State Forestry in the West ; and Dr. Fernow, as President of the Society, developed his views on the needs of the Society. The most notable contribution in the program of the preceding day was the address of Mr. Greeley on National Forestry. At the forest products exposition in Chicago and New York the Forest Service exhibited two models to show proper methods of logging. The models were supplemented by a graphic chart, which shows the increase of timber sales on the national forests from 1905 to 191 3, inclusive. In 1905, the timber sold from the national forests aggregated 96,000,000 board feet, which brought the government not more than $85,000. Three years later the amount of timber sold increased to nearly 390,000,000 board feet, and the money received rose to $735,000. In 191 1, 830,000,000 board feet sold for more than $2,000,000, and in 1913 more than 2,000,000,000 feet brought in contracts amounting to $4,500,000 Not all this money was received in any one year, because na- News and Notes. 301 tional forest timber is sold on contracts which range from one to 25 years, and it is paid for as cut. Dr. B. E. Fernow, dean of the forest school of the University of Toronto, and Bristow Adams, of the U. S. Forest Service, have been elected President and Secretary, respectively, of the Society of American Foresters, one of the two organizations of professional foresters of the western hemisphere, the other being the Canadian Society of Forest Engineers, of which Dr. Fernow is also President. The Seventh Congress of the International Union of Experi- mental Forest Institutes will be held in Budapest, Hungary, from the 7th to 17th September inclusive. Excursions will be made to Szabadka, Palics, Kiralyhalom, Horgosi-Kiralyhalom, Szeged, Temesvar, Karasjeszeno, Vadaszerdoo, Godollo, Garamberzence, Selmecbanya, Besztercebanya, Fenyohaza, Likava, Csorbato, and Tatralomnic. The sale of one billion feet of western yellow pine timber from the Kaibab National Forest in northern Arizona was ap- proved by the Secretary of Agriculture. In order to get this timber out it will be necessary to build a railroad approximately 200 miles long. Such a railroad will connect Colorado and Utah with the world-famous Grand Canyon of the Colorado, which hitherto has been accessible only from the south. For several years the construction of such a railroad has been considered by various capitalists, but it has been stated that the lack of assured immediate traffic was an effectual barrier. It is pointed out, however, that a contract for a billion feet of timber will overcome this difficulty by providing a commodity for trans- portation which, together with tourist and local traffic, will place the project on a paying basis practically from the outset. The U. S. Forester says, however, that the Kaibab Forest is one of the most beautiful in America, and gives assurance that the marketing of the mature crop of timber will not be allowed to mar the scenic beauty of the region. The investment necessary to make this timber accessible will amount to more than $3,000,000. By placing this quantity of timber before the lumbermen of the country Forest Service of- 302 forestry Quarterly. ficials believe that development in other directions may be looked for, the necessary railway making accessible heretofore un- developed resources. The whole region is rich in agricultural land, in cattle and sheep range, and in coal and copper deposits, as well as in timber. Bids for the timber will be received up to the middle of June, 1914, and three years will be allowed for the building of the railroad and mills, and 25 years for the cutting of the timber. The stumpage rates, however, will be readjusted at the end of each five-year period of the contract, the readjustments being based on the then current lumber prices. The annual cut will be not less than 40 million feet, most of which will be readily sold in the large consuming lumber markets of Utah and Colorado. The Kaibab forest is one of the most heavily timbered in the southwest, the stand of timber being broken only occasionally by beautiful meadows or openings locally known as parks. Lumber- men who have visited it consider the country ideally adapted to logging. There are, altogether, two billion feet of timber, of which more than one billion feet are mature and ready for cut- ting. Arrangements have just been made for the sale of 40 million feet of timber on the Tongass National Forest in Alaska. This forest is cut up by bays and inlets, some of which give an op- portunity for taking the -timber from the mill to the decks of ocean-going steamers. The Tongass forest is now self-supporting its lumber product being used largely in local industries, much going into boxes for canned salmon. The Secretary of Agriculture has designated a new area in the southern Appalachians in which he thinks that lands should be purchased by the Government for forest purposes in accordance with the provisions of the Weeks law. This area is in north- western Alabama, and includes 152,960 acres at the headwaters of the Warrior River in Lawrence and Winston counties. For a number of years extensive improvements by the Government have been under construction on the Tombigbee and the War- rior rivers, and a system of locks and dams to provide for 360 miles of navigable stream is now near completion. The presence of a forest cover to protect the headwaters of the News and Xo'cs. 303 streams and to help equalize their flow being considered ex- tremely important, the location of a government forest area in the region is found advisable. This new area, in which purchases will be made, is at the ex- treme southern portion of the Appalachian region, about 150 miles from the nearest lands which the Government has pur- chased hitherto. The new area is almost completely covered with forest ; 92 per cent, of it has never been cleared, and of the 8 per cent, upon which clearing has been attempted 3 per cent, has been abandoned and is reverting to forest growth. There is a merchantable stand of hardwood and pine timber, but there has been no great amount of lumbering because the locality has been too far from transportation facilities. One striking thing about the region is that, although it has been settled for more than 100 years, a part of the land is still public domain, fully 9,000 acres never having been taken up by private owners under the various land laws. These lands have now been withdrawn from settlement, and request has been made that they be set aside as a nucleus for the proposed National Forest, the purchase of private lands being also undertaken, that another Forest of sufficient size for economical protection and administration may be built up. The Government of the United States has just offered for sale two tracts of timber on Lolo Creek within the Clearwater Na- tional Forest, Idaho, aggregating 600 million feet of saw timber and 350 thousand cedar poles, together with a considerable amount of material for piling, shingles, and posts. The prices, which represent the lowest rates which will be considered for the saw timber, range from $3.50 for Green White Pine to 50 cents a thousand for Douglas Fir, Western Larch, and cedar. The prices of poles range from 5 cents to $2.40 apiece, depending upon the size. The readjustment of boundaries has resulted in a total reduc- tion of gross area on the Paulina and Deschutes National For- ests, Oregon, of about 400,000 acres. The lands eliminated are located in the east-central part of the State, a considerable portion being on pumice lands of low fertility and little value for present or future forest purposes. A portion is located near the Des- 304 Forestry Quarterly. chutes River, and already comprises a large percentage of private lar^ds, and includes two towns. These eliminations are a part of the work of boundary examinations initiated 5 or 6 years ago, which is resulting in fixing, after careful survey, the definite boundaries of those lands which should remain permanently in forests. Foresters' and lumbermen see a strong argument for forestry in the following decision of the Treasury Department, namely that " the gain from the cutting and disposal of stumpage is real- ized in the year during which the timber is cut and disposed of, and that the amount received in excess of the cost of such timber is profit, and should be so accounted for as income for that year." According to their interpretation, this decision means that no timberlands shall be subject to the tax until the timber is cut and marketed and that then only the profit will be subject to an in- come tax assessment. In other words, all costs will be deducted before the tax is levied, and these will cover the cost of grow- ing the timber, including the cost of planting where necessary and of protecting the growing crop from fire and other depredation. Nearly 17,000 acres have just been added by act of Congress to the Caribou National Forest, Idaho. This is one of the first of such additions through congressional action, instead of presi- dential proclamation under the law of 1907, and is the largest so far made by direct legislation. The addition was made upon the petition of residents of the city of Montpelier, Idaho, the area included being the water- shed of the stream which furnishes the city's water supply. Direct seeding of Lodgepole Pine has been successful without exception on the Arapaho National Forest, Colorado. Several of the areas sown two and three years ago show from 5,000 to 10,000 seedlings per acre. Western Yellow Pine cones, to the amount of 6,377 bushels, obtained on the Bitterroot National Forest, Montana, yielded 9,482 pounds of seed. The average cost of the extracted seed was 41 cents per pound. News and Notes. 305 New grazing regulations for the Dominion Forest Reserves, similar to those in operation on the National Forest of the United States, permit the keeping of a much larger number of stock by a much greater number of stock-owners, and also make available to the Dominion Forest Service a source of revenue second only to that derived from the management of the timber on these re- serves. Unfortunately, due to the clamor of the cattle interest, the regulations have been suspended in British Columbia. Foresters who have just returned from winter work in the White Mountains of New Hampshire report that, while some hardship is entailed, as much can be accomplished in the dead of winter as in summer. During the past winter two camps of men have been estimating and valuing the forests which the Government contemplates pur- chasing on the slopes of the White Mountains. Because of the softness of the constantly falling snow, the work was done mainly on snowshoes. At times the temperature has been around 20 degrees below zero for considerable periods, and at times nearly 40 degrees below. The crews were housed in winter camps like those of the lumberjacks, and during the short winter days they were out by daylight and did not return until dark. The work of the crews required continuous walking. Diameters of trees were measured and the number of logs estimated in all merchantable trees growing on parallel strips 4 yards wide and 40 rods apart. From these estimates the full amount of timber was calculated, especially stormy days being used to work up data. During the whole winter it was noted that stormy days caused no more loss of time than in summer, and the health of the men in the party was as a rule better than in hot weather. In replacing a railroad trestle, recently burned, along the north shore of Great Salt Lake, engineers have just found that the piles are still perfectly sound after 43 years of service. Looking for the cause, since these were only of local pine and fir, they found the timbers were impregnated throughout with salt from the lake. The first transcontinental telegraph line was transferred, when the railroad was built, to follow its right of way, and the old 3o6 Forestry Quarterly. telegraph poles were sawed off at the ground. Upon recent ex- amination the butts left in the ground in the salt desert have been found, although 50 years have passed since the poles were cut off, to be perfectly sound. Experts in the U. S. Forest Service who have been investi- gating the preservative treatment of timber offer the suggestion that ties and poles which have been immersed for some time in the waters of the lake, which, being so much saltier than that of the ocean, is practically a saturate solution, ought to be im- pervious to decay if the salt is not leached out by the action of the elements. It has been suggested that this can be guarded against by painting the butt of the pole with a coat of creosote, which will keep out the moisture and keep in the salt. California State inspectors at San Francisco have found a new canker disease on chestnut trees recently imported from Japan. According to Dr. Haven Metcalf, the government's ex- pert on such diseases, this appears to be of the same type as the chestnut blight which is ravaging the forests of the eastern United States, and it is possible that the new disease would be equally as destructive if it became established in this country. At the polls next November the people of Minnesota are to vote on an amendment to the constitution for the establishment of State Forests. The State Forestry Association started the campaign for this object at its 38th annual meeting at St. Paul on March 24. It is pointed out that Minnesota has 15 million acres of non- agricultural soil which should come under forest management. Nearly 4,000 acres were reforested by the Forest Service in Montana and northern Idaho during 1913, at an average cost of $7.50 an acre. The U. S. Forest Service issues a note on the use of the Mon- terey Pine in New Zealand. The writer of the note refers to the name used, "Remarkable Pine," as given by the New Zea- landers on account of its rapid growth, without realizing that this is simply the translation of its species name insignis! The tree is remarkable, indeed, by its small range of distribu- Neivs and Notes. 307 tion in spite of its evident adaptability to untoward conditions. Tn New Zealand, as well as in South Australia, in the semi- arid country, plantations of this pine have been made 30 to 40 years ago, which furnish now considerable material for fruit boxes especially, making 75 to 100 M board feet of inferior stuff in 30 years. An individual tree is reported as containing 6,000 feet at 46 years of age, rivaling the Eucalypts. The character of the material is, to be sure, inferior. The forestry division of the geological and economic survey of North Carolina issues separate reports of the forest resources cf each county in the State, each report being a concise state- ment occupying less than four printed pages. It is intended by the survey that these reports of individual counties may be reprinted by the local newspapers, because in that way the specific local information will be given to the people in the cheapest and most direct way. The Chinese national conservation bureau is considering re- forestation at the headwaters of the Yellow River. The Govern- ment report shows that this will ameliorate the torrents and cause a more regular flow from the now denuded uplands. It is acknowledged, however, that this reforestation may not have an appreciable effect within the life-time of the present gen- eration The imports of matches into China greatly exceed in value any other wood product. Most of the matches come in from Japan. A novel course is to be instituted at Harvard University next session, the Graduate School of Business Administration and the Forestry School co-operating. Ostensibly this course is in- stituted to furnish "scientific knowledge of the business of manu- facturing and marketing lumber," with the expectation that im- provements may be introduced by which loss under present methods may be turned into profits. Mr. John M. Gries, of the United States Bureau of Corporations, who made the in- vestigation into the timber trust, is to carry on this course. This course is to cover two years, and is made up of a combina- 3o8 Forestry Quarterly. tion of parts of suitable courses already given in the Business School, together with some work in the forestry school for those who have had no previous training in forestry. The first year will include, besides new courses on the manufacture of lumber and on general lumbering to be given by Mr. Gries, cer- tain Business School courses on accounting, marketing, factory management, business statistics and investments. In the second year the Business School courses will be three ; in industrial accounting, including cost accounting; corporation finance and an advanced course on manufacturing made up of parts of two existing courses. Lumbering occupies the whole of the second half year, which will be devoted to special investigations in the field, each student being given a large problem in the lumber- ing business on which he will write his graduation thesis. Besides this, there is also needed a kind of forestry research not hitherto available, to which the Harvard School of Forestry will now devote itself, turning over the subject of lumbering to the Business School. Within the accepted field of forestry there are several lines that give ample room for the training of the specialist. Allied with the business of lumbering, as well as with forestry, are studies in wood technology, — research to discover, for in- stance, what new sources of supply there are for wood pulp, which is a pressing economic problem ; what uses can be found for small trees, below accepted lumber sizes ; what are the most practicable methods of reproducing forests; what processes of preservative or other chemical treatment will bring into use woods not suited to existing needs ; and how diseases and in- sect pests can be controlled. Such things involve advanced tech- nical research closely linked with economic conditions ; and in this direction it is expected that the Forestry School will con- tribute to the broadening of the business side of lumbering as presented in the Business School. The legislature of North Dakota has instituted a State School of Forestry at Bottineau. From the circular issued by its presi- dent, Fred. W. Smith, who is at the same time State Forester, it would appear that its function is not to educate foresters, but to educate the public and mainly in tree planting, the school dis- A^ews and Xotcs. 309 tributing plant material and information as to its use free of charge. Undoubtedly the Nestor of our profession, the Oberforstin- spektor of the Swiss Federation, Dr. J. Coaz, retired from ac- tive service on April 30 of this year, at the ripe age of over 90 years. A service of 63 years, in various capacities, lies behind him, 40 years of which (since 1874) he has' been the head of the Swiss forest service. More than that! He has been the cr- organizer of that service from its beginning, and was the fore- most propagandist in securing its inauguration — the federal super- vision of all forest services of Switzerland. In an endeavor to get the public interested in the preservation of our native forests, as far as can be done without loss to the owners, and the establishment of forest plantings on all land that is not suitable for successful farming, the State Board of For- estry of Minnesota has this year and last year offered to public school pupils money prizes for essays on forest influences, the fol- lowing being the order required : Relation to rainfall, to tempera- ture, to animal life, to industries, and to sanitation. Mr. John S. Bates, B. A., B. Sc, one of the foremost authori- ties on wood pulp manufacture in America, has been appointed Superintendent of the Forest Products Laboratories, McGill Uni- versity, Montreal. Mr. John Appleton, Yale '04, died on April 2, at Bangor, Me. Mr. Appleton was two years in the U. S. Forest Service, after which he began private practice as a consulting forest engineer at Bangor, being associated with Mr. B. S. Viles, and later with Mr. J. W. Sewall. Besides mapping and estimating large areas of trmberland, he organized a tree surgery department with head- quarters later in New York. The work on the Yale and Bowdoin campus was done under his direction.

The following experiment was conducted on the lands of the Northeastern Forestry Company at Cheshire, Connecticut. It was made possible through the kindness of the Superintendent, Mr. F. S. Baker, in supplying material and ground. The object was to determine to what extent seedlings would recover after having had the roots exposed to sun and wind. A slight amount of exposure is inevitable in the lifting, bundling, packing and transplanting. The question was : will the plants re- cover after exposure for hours, or is exposure for minutes fatal ? The chief factors influencing the result, are : 1. The sun's altitude. 2. The latitude. 3. The absolute and relative altitudes and the locality. 4. The time of day. 5. The cloudiness and place of exposure. 6. The temperature. 7. The humidity. 8. The precipitation. 9. The direction and velocity of the wind. 10. The treatment after exposure. 11. The species. 12. The age and character of the material. 13. The soil in which planted after exposure. 14. The weather after transplanting. ^- As to the sun's altitude, only one experiment was conducted, ^ beginning on April 19th the following table (taken from P. N. 312 Forestry Quarterly. Hasluck, Book of Photography, 1905, p. 88, having been pre- pared by Prof. A. Scott) shows the actinic (not thermal) ratios for the various months and hours for latitude north 40". May Apr. Mar. Feb.

The nursery is in about 41** 30' N. Lat., 15 miles from salt water (New Haven Harbor), at an altitude of about 200 ft. above mean sea level, on level ground. The sun's heat evidently varies in intensity from hour to hour, and a series of hourly exposures might be made through the day, but it was desired to try prolonged exposures as well, and these, as, for instance, a lo-hour exposure, are evidently rather limited as to time of day. A series of exposures varying from one another in duration by ten minutes was, however, con- ducted about noon. It is obvious that a cloudy day would be less harmful than a brilliantly clear day. The day chosen happened to be clear though not brilliant (see Table i), probably as nearly average a day as obtainable. In the nursery practice much of the work is done under shelter of some kind. Stringing the plants in the transplanting boards is done under the shelter of burlap shanties which give considerable protection from wind and perhaps half protection from sun. Some of the counting and bundling is done here, also. The greater part of this, however, as well as all the packing, is done in the counting and packing sheds which afiford complete sun protection and nearly complete wind pro- tection, and it was only in the packing shed that the shade ex- posures were made. The temperature, the humidity, and the precipitation do not need comment, though perhaps the significance of the humidity Drying Roots of Seedlings. 313 is at times overlooked. The drier the air, the more rapid the evaporation. As to the wind, it is an elementary principle of physics that rate of evaporation is increased by increased movement of air over the body from which the evaporation occurs. The in- fluence of wind direction would probably be included under other factors. It might influence humidity, temperature, precipitation, velocity. In the present instance, the south wind is apt to be warm, and perhaps, moist, though not markedly so. The exposures were made on pine planks. This is prob- ably a severer test than it would be to leave them on the ground as would probably happen in practice. As suggested above, the plants may be either replanted or packed for shipment after exposure. In some cases the roots are puddled whether for shipment or transplanting. In the present experiment all the exposures in a series w^ere started at the same time the successive lots being stopped at different times and placed with the roots in wet sphagnum in the pack- ing shed until evening, when all were planted after sunset. It has been suggested that perhaps the wet moss had a tendency to revive the exposed plants, but it is the treatment they would receive if shipped to a customer. From the standpoint of im- mediate transplanting it might have been better to start the ex- posures at dift'erent times, and stop them all at once, transplant- ing immediately. It was, however, desired to plant after sun- set to reduce, as much as possible, untimed harmful exposure, and to use the method suggested would have involved continu- ing the exposure for a time (an hour or two or half an hour, perhaps) after the sun at least, and possibly the wind had con- siderably declined in destructive effects. True, commercially, plants would never be planted at night, but it is' believed the treatment adopted eliminated some variables difficult to de- termine. To avoid having so many plants that the handling would lack precision because of mere numbers, but two species (Pinus strobus and Pinus resinosa) were used, and only three year seedlings of these, two of each kind to each set. Even so the results show a considerable variation. The individuals used were not chosen, but taken as they came from the bed. 314 Forestry Quarterly. The place in which the plants are planted would undoubtedly have a determining influence in the case of weakened plants, as would also the weather conditions after planting but a con- sideration of these is scarcely within the province of the present investigations. As variables they may both be ignored in the present instance. It is realized that these investigations are by no means com- plete. From the scientific standpoint it was an error not to have unexposed checks given otherwise the same treatment as the exposed plants', though from the commercial standpoint it is significant that some of the plants lived even after an exposure of several hours. Merely two plants for each variable allowed for, time of day, species, place of exposure, length of exposure, is a small number but the reason has, it is believed, been satis- factorily stated above. A recent article in "Forestry Quarterly" (vol 12, p. 31) is based upon experiments along similar lines started April 29th and kept under observation until the beginning of August. Such extended study is desirable, but was imprac- ticable in the present instance. Exposure immediately upon lift- ing might work for more accurate results than the method used (see infra.) The conduct of the experiment was as follows : The approximate number of plants of each species needed was counted roughly in the bed and a double quantity dug, after sunset, with the earth adhering to the roots, like a sod. These sods were heeled in over night in the packing shed. The next morning the requisite number of plants was taken, the original earth shaken from the roots, and the exposures begun, the plants being exposed on pine boards and held down against the wind by a narrow strip of wood laid across the root collars and weighted with rocks in such a way that no shade was cast upon the roots. (A transplanting board might be more satisfactory, though it would probably be more difficult to remove a few plants at a time than in the case here described.) As before stated, the plants were taken as they came, except that care was exercised to use the ones near the center of the clump, and dead ones were discarded. The exposures were thus begun, the Red pine being started at 6.40, the White at 6.45. One group was left on the Drying Roots of Seedlings. 315 bench in the packing shed ; the other was placed in the full sun and wind. At one-hour intervals (approximately the table [i] shows the time to the nearest five minutes) two Red pines and two White pines from the sun and from the shed were labeled with the time and character of the exposure, and the roots packed in wet sphagnum. A similar series was begun at 11.45. The interval being 10 minutes*, and completed at 12.45. The exposures, with an hourly interval were completed at 4.40 p. m. All were planted about 7 o'clock in the evening, care being taken to expose the roots as little as possible, the label being re- moved from the bundle and fastened to one Red pine before the roots were uncovered, the four being then planted in a trench in regular order, and with the sets in a regular order, as rapidly as possible. The spacing was 1.5 inches on an average. Table I gives a correlation of the periods of exposure with the meteorological data. These latter were supplied by the Observer of the United States Weather Bureau at New Haven, Conn., 15 miles south of the nursery. After planting the weather was' rather favorable. The first rain occurred on the 20th. The plants were not watered dur- ing the progress of the experiment. Weeds were pulled oc- casionally. Observations were made at weekly intervals be- ginning with the fourteenth day after planting. The results are shown in tables II and III. The final observations are given in table III which shows the condition of the plants in each case about two months after transplanting. Owing to the small num- ber of plants used it is hardly practicable to give percentage re- sults. It can be seen, however, that some of the plants which had been exposed several hours were still living at the end of two months. It is perhaps safe to say that an exposure of two hours in the sun and perhaps more in the shade is not necessarily fatal (though of course this exposure was in the earlier part of the day.) The Red pine seems to have been affected to a greater extent than the White, but it is here that the lack of an *Sun exposure for this series was 2 min. in shed, the rest (8, 18, etc.) in full sun. 3i6 Forestry Quarterly. unexposed check is especially felt. the large number of Red pines shade.

Large spaces do not occur around single trees, as a rule, but around groups of trees. It seems probable that the crowding together of the species rather aflfords a measure of protection by shading the ground and thus lessening evaporation. When the trees grow into poles and veterans, the competition for light is the factor which thins out their numbers more especially than the competition for moisture. In the second case the stand is more uniform than in the first, but the same grouping of the trees is still evident enough. In the first case the average tree is 21 inches D. B. H., the volume, 340 Forestry Quarterly. therefore, should approach 31 M., and in the second case where the D. B. H. of the average tree is 24" the volume should approach 37 M. As a matter of fact, the volumes on these two acres are respectively only 16,600 and 31,000 B. M. Probably many years will be required before it will be pos- sible, in this country, to obtain very extensive normal forests of Yellow pine. Trees will be spaced, not usually by planting as is' the case in most of the German forests, but they will be spaced by means of the axe. That is, the stands will be thinned out, as the increasing size of the trees require, and the spacing will consequently be more or less rough. On very dry soils it will be necessary to make the spacing greater than on moist, for the reason that on a moist soil a tree can put up with a greater degree of shade. The shade is compensated for by the increased allowance of moisture. It has been the endeavor in this report to deal exclusively with average conditions of soil and climate as' they exist. Extreme conditions of soil and climate will al- ways require special treatment. In conclusion, it may be said that possibly various statements in this report may lend themselves to criticism as not being suf- ficiently backed up by evidence. It was necessary to make this study entirely a side-issue along with more immediately imperative work of another sort, so that the procuring of much field data was impossible. It is felt, however, that the subject treated is an important one, and, before concluding, it is desired to call at- tention once more to the method described earlier in this report, of measuring the areas occupied by the crowns of Yellow pine, which, it is thought, yielded very satisfactory results. The importance of knowing the crown area of trees of all species, for different diameter classes will become increasingly important as it becomes more and more possible and necessary to practice intensive forestry in this country. In planting and thinning, it will be of value in determining the most advantageous spacing of the young trees. In forest management, it will as- sist in estimating the probable future yield of stands. By means of sample plots, the various habits and peculiarities of the different species can be graphically shown and compared in a most instructive manner. NOTES OX STRIP MAPPING FOR INTENSIVE RE- CONNAISSANCE. By a. F. Kerr. The objects of intensive reconnaissance are to secure: ist an accurate map, 2nd an estimate of the timber, and 3rd other data necessary for the proper management of the Forest — all at a rea- sonable cost. The strip survey has been generally adopted as' the best system for securing this information, for the following reasons : — The gridiron arrangement of the strips permits of the simplest and most effective methods of control, and the most accurate location of details in mapping, and it fits well into the rectangular scheme of the Land Office Survey. The gross estimates are practically reduced to a mathematical basis, and may be worked up for con- veniently sized, legal subdivisions. The application of correc- tion factors for defect, etc., require judgment, but the bulk of the estimating can be done by inexperienced and, consequently, low-salaried men. The question of control is an extensive one in itself and, for that reason, will not be considered here. In general the location of data on the strip map depends upon pacing for distances and the aneroid barometer or Abney hand level for elevations. Topography is shown by contours or form lines drawn as the mapper proceeds along the compass course. This system is usually applied in one of two ways. Since the Abney level is merely a substitute for the barometer in either plan it need not be considered separately. By the one method which was commonly used, "form lines" are drawn on each strip in accordance with the barometer readings, and entirely independent of the form lines on adjacent strips. That is, the form lines of adjoining strips are not con- nected in the field but simply serve to indicate the direction that the contours will take on the finished map. These form lines are drawn on the map as' final contours, in the office, in accordance with the "corrected" barometer readings. By the other method actual contours are drawn, and are con- 342 h ores try Quarterly. nected as far as possible in the field. They are based, not upon barometer readings alone but, upon differences' in elevation deter- mined by the barometer and checked by judgment and by angle and distance. In other words this map is completed in the field, and is dependent to a certain extent upon the judgment of the topographer. Barometer and time readings are recorded upon the field map at regular intervals as in the first case, but are dis- regarded until the map is turned in for final adjustment. The important difference between these two methods is, that in the first case form lines are not connected in the field while in the second case form lines are connected in the field. It is for the purpose of discussing the relative merits of these methods' that this paper is written. The barometer and a reasonable ability to pace constitute the new topographer's chief assets, and perhaps because of the rela- tive accuracy of the barometer, he is inclined to place unlimited confidence in it. Considering now the method first described : — the topographer starts from a control stake of known elevation and when the barometer shows a change equal to the contour interval to be used he unquestioningly indicates it by a line drawn across the strip, showing the general direction of a contour at that point. Other form lines, at irregular intervals, are drawn to indicate minor changes in slope. He proceeds along the compass course concentrating his attention upon the mechanical factors, his pacing and the barometer. Important topographic features will be noted superficially, but the business of properly indicating barometer form lines on the strip occupies his mind. He misses the general scheme of things entirely. Succeeding strips will be done in the same manner. Each strip is a unit in itself, since no individual contour, and therefore no particular land form of one strip is actually connected with the complementary elements of the same land form on adjoining strips. It is seldom that an important topographic feature is complete in a single strip, and if the portion on each strip is sketched as a detached fragment the feature as a whole is lost. No matter how careful the topographer may be, work done in this manner will become mechanical and the form lines across the strip will be simply a graphic representation of the barometer readings taken. Mapping for Intensive Reconnaissance. 343 It is a fact, that should require no argument, that a map made in this manner can be no more accurate than the topographer's mental conception of it. If he does not connect his lines on the sheet and thus develop a complete and tangible representation of succeeding impressions he can not retain a clear idea of the country over which he passes. A given land form seen from one strip may have a decidedly different appearance when seen from the next strip, and the form lines representing it may be entirely unconformable. In the office a case of this kind can be settled only by guess work. Following such a method the mapper will perhaps develop speed and, to some extent at least, his sketching ability, but his judgment of perspective, of topographic forms, and of the inter- relation of physical features will certainly remain latent. The stock argument in favor of this method is that "owing to atmospheric changes which can not be allowed for in the field the topographer is liable to connect form lines' of different eleva- tions." Such an argument is in itself an admission that the work is being done mechanically. It says in effect that the barometer readings must stand, and that the topographer may not use his judgment as to whether or not the reading is correct. It is based on the assumption that a topographic map depends for its value upon the exact location of certain contours, rather than on the proper relationship of the contours to each other. If it were possible to locate contours accurately throughout their entire length, and at close enough intervals, the resulting map would necessarily be a correct representation of the topo- graphy. But with reconnaissance work in rough country and heavy timber it is only possible to approximate their locations, at points from an eighth to a quarter of a mile apart, and usually at vertical intervals of 100 feet. It is evident that under such cir- cumstances the exact location alone of a few points will not give a very reliable map. To produce a reasonably accurate map under the conditions which ordinarily obtain, requires an understanding of physio- graphic features, of the interrelation of land forms, of perspec- tive, and more than this it requires topographic sense and imagina- tion. To concentrate attention on the strip line and to locate contours 344 Forestry Quarterly. by arbitrary barometer readings is to develope only the mechanical ability of the mapper, and to positively weaken his topographic sense. A completed field sketch made in such a manner will show scarcely a single definite feature. The lines on it merely suggest the form which the draftsman is supposed to develope. It is' practically unintelligible until it has been thoroughly worked over. In this process it usually loses whatever character it m.ay origin- ally have had, and takes on the wooden appearance of the conven- tional map, with long regular curves, contours uniformly spaced and streams all traced in the same pattern. Whatever the method of securing the data, the purpose of a finished, contour map is to convey to the user a correct and definite impression of the topography of the country which it covers. It is obvious that no contour can be accurately drawn on the map until it is first developed in the mind of the topo- grapher. Therefore, anything which will give him a better grasp of the details or a more thorough knowledge of their arrange- ment, will tend toward the production of a better map. If the mapper can be made to actually see and appreciate the controlling topographic features of an area, the problem of rep- resenting them on the map sheet will ofifer little difficulty. The plan of connecting in the field, contours of approxi- mate elevation, is a means toward this end. It is simply the application to strip mapping, of a principle of extensive recon- naissance in which large areas must be mapped from a few points. In such work it is impossible to depend altogether on artificial means for the location of contours, and the topographer is forced to rely to a certain extent upon his eye and his judgment. Ap- plied to strip mapping it does away with the purely mechanical use of the barometer and with the idea that "the draftsman can distribute the error," and it places the responsibility for the ac- curacy of the map squarely upon the topographer. The barometer is used as far as it can be relied upon, but the actual location of many of the contours on the ground is largely a matter of judg- ment. The fact that the contours of separate strips must be connected makes it essential that special thought be given to every feature. The lines can not be drawn carelessly, merely as a suggestion to the draftsman of the probable direction of the final contour. They ■ Mapping for Intensive Reconnaissance. 345 are, in the best judgment of the topographer, the final contours themselves. Intermediate form lines to show minor changes are used only in exceptional cases, as their presence confuses the map and there is' little advantage in putting indefinite data on the field sketch which will be eliminated from the final map. It may be argued that, since only a limited portion of the area he is covering is visible to the mapper, he should not attempt to sketch in those portions which can not be seen. There is no rea- son however to suppose that this part of the map can be supplied any more accuately in the oflfice. The details are in the field, and there the topographer has the advantage of being able to see at least a part of the feature he wishes to represent, and from this can make a reasonably good estimate of the unseen portion. In the office it is a sheer guess. In order that the field sketch may be retained exactly as it is turned in, a carbon copy is made and the corrected barometer readings placed on it. The necessary adjustments are then made on the copy. Such adjustments usually consist in a slight shifting of some portions of the map in order to correct for errors in bearing and distance, and to check up the contours with the cor- rected elevations. It is very seldom that any change in the rel- ative positions of the contours is required, and the finished map loses none of the character of the original sketch. To sum up : — the first method encourages the use of the baro- meter as a crutch, and bases its claim for accuracy chiefly upon the accuracy of the barometer readings. Nothing definite, in the manner of representing topographic data on the field sketch is required, and nothing definite is ob- tained. Since it is the mechanical element that is emphasized, rather than the personal there is little improvement in the quality of the maps produced. By the second method the location of the contours is based to some extent upon the topographer's judgment. The barometer readings are used especially in making the final adjustments, that is, backed by the best judgment of the topographer, as well as by the barometer. Everv feature must be shown on the field sketch in a complete 346 forestry Quarterly. and definite form. No gaps are left to be filled in by a drafts- man. The map is a direct expression of the topographer's personality, and will improve in quality as' the topographer gains in experience. The first method is unsatisfactory in many respects, under conditions such as those found on the west side Forests, The second method is suggested as a possible improvement. The foregoing observations are based on a thorough trial of both methods, covering areas aggregating over 50,000 acres on the west slope of the Cascades, and on the opinions of several topogrnplier'j whose combined experience covers at least six season's work. [The experience of the Forest Service corroborates the con- clusions of the writer, and the Service's instructions for 1913 definitely provided for the use of the second method only. Ed ] OBTAINING VERTICAL CONTROL OF PRACTICAL VALUE WITH THE ABNEY HAND LEVEL. By William J. Paeth. Method and system become of more and more importance as the work of Reconnaissance is done on a more intensive scale. The object of the survey is to obtain, at all times, as much data of standard value as possible, in a given time, and with the amount of money allowed for the work. In order to approach this ideal, the method and system of doing the work must be adapted to the conditions encountered while doing each portion of the work. Any one system will not result in this maximum efficiency, at all times, and under all circumstances. Understanding, however, the nature and effect of the local conditions under which the work is being performed, the method and system can be chosen scientifically to meet the peculiar de- mands of the situation, and this method and system should be changed at will as soon as changing factors and influences war- rant the use of another method. The maps obtained by cruising methods now employed vary greatly in character and accuracy, depending upon the degree of intensiveness with which the work is done. However, maps of the greatest practical value and efficiency must be consistently accurate within the limits of accuracy determined upon for the type of map being made. To be consistently accurate the vertical control and the horizontal control must be obtained with equal degrees of precision. It would be out of place to obtain the horizontal control accurately and to plot the vertical control from less' accurate vertical location. A practically accurate forest map is not always obtained unless all the factors affecting the accuracy of the methods used are considered and understood. As stated before, methods must be chosen to fit local needs. Circumstances may affect the balance in accuracy between verti- cal and horizontal control and in order to make the map con- sistently accurate new methods of obtaining either the horizontal or vertical control must be adopted. To illustrate; the compass man may be able to work within the prescribed limits of error 348 Forestry Quarterly. imposed upon his work in horizontal location, at the same time however, local factors may so influence his work in obtaining elevations with an aneroid that the vertical location will be de- cidedly less accurate than his horizontal location. As a conse- quence a large error is' introduced into the horizontal location of the contour. The importance of the accurate horizontal location of con- tours is apt to be overlooked when only the representation of the general character of the topography is desired in the topo- graphic map. Maps prepared by extensive methods, on a scale of one or two inches to the mile, will be of this kind, and these extensive maps will be consistently accurate because the horizontal control and the vertical control are obtained with relatively equal accuracy. If however, a map is prepared by supposedly intensive methods the resulting map is more than a general representa- tion of the ground and in order to give this technical character to the topographic map prepared by intensive methods the com- passman must appreciate the necessity for preserving the balance between accuracy in vertical and accuracy in horizontal location. The accurate horizontal location of a contour is perhaps of greatest importance to the timber appraiser, the logger, and the trail and road builder. The minimum grade of a haul is de- termined by the difiference in elevation between two points and the horizontal distance between these two points. A topographic map having this quality of consistent accuracy will show the timber appraiser, logger and road builder a fairly accurate ap- proximation of the grades within the limits of accuracy of the map. An inconsistently accurate map will not, because the horizontal location of the contour is not reliable. As a rule, in the construction of forest maps it is more dif- ficult to get accurate results in the vertical location than in the horizontal. The error in horizontal location can be corrected and distributed between stations along the strip line so that the final results will be well within the standard limits of ac- curacy. Experience has demonstrated, however, that corrected aneroid elevations, under some conditions, still exhibit an error in vertical location, when compared with bench marks, out of all proportion to the error in horizontal location. Under favor- able circumstances, on the other hand, the elevations secured The Abney Hand Level. 349 with the aneroid compare favorably with bench marks and the resultant accuracy is well within the limits of the precision of the horizontal control. In order to secure a consistently accurate topographic map of greatest practical value to the timber appraiser, logger, trail and road builder, and forester, the conditions affecting the work with the aneroid should be studied, with the end in view, that some other method of obtaining vertical control may be substi- tuted at the time when local factors affect the work with the aneroid so unfavorably as to destroy the value of the results for the construction of the type of forest map desired. The Aneroid Barometer. The aneroid is not always an accurate instrument and the errors encountered in working with the aneroid can hardly be controlled by the man in the field. The elevations arc not secured by geometric principles. The levels are determined by an intricate mechanism which measures the weight of the column of air pressing upon the top of a shallow cylindrical box. The top is composed of corrugated metal so elastic as to respond to changes in pressure. The interior of the box is in vacuum. When the atmospheric pressure decreases the elasticity of the corrugated top presses it outward, and when the atmospheric pressure increases the top is pressed inwards. This movement of the corrugated top is communicated to an indexed dial by means of a complex system of multiplying levers, chains, and springs. The possibilities for error in the mechanism of such an instrument are apparent. No system of office corrections will compensate for them. The errors caused by the daily and hourly changes in atmospheric pressure can be eliminated by determining these changes with a stationary barometer in camp and correcting the elevations taken during the day in the field. This, however, can only be done with an accurate camp baro- meter, preferably a mercurial barometer. Two aneroids read in camp will often vary considerably even if not moved and it can not be determined which is the more accurate. The errors peculiar to each instrument in the field however, can not be de- tected and remain undiscovered. Errors in the aneroid readings- 350 Forestry Quarterly. often become obvious to the compassman and he has no means of accurately correcting them. The instrumental errors of the aneroid are outlined as fol- lows in Wilson's book on Topographic Surveying: — 1. The elasticity of the corrugated top of the vacuum chamber is affected by rapid changes in pressure. 2. The readings are affected by changes in temperature which it is impossible to readily compensate. 3. The different spaces on the scale are seldom correct relatively one to the other, but the scale of pressure in inches is more accurate than the scale of feet since the latter contains the error due to the formiplae by which it was graduated. 4. The weight of the instrument affects its indications, its readings differing in accordance with the position in which it is held. 5. It lacks in sensitiveness frequently not responding quickly to changes in altitude. 6. The chains and levers sometimes fail to quickly respond to the movement required of them. 7. Because of its containing so many mechanical parts these are sub- ject to shifting or jarring by movement made in transporting it, the only remedy for which is frequent comparison with known altitudes or a mercurial barometer/' It is readily understood that most of these errors are different for each instrument in the field and that no office correction can eliminate them. No corrections based on camp readings can re- move the errors in the field barometers caused by other factors than atmospheric changes. The only possible method of cor- recting or eliminating these other errors of the aneroid is in the field by the compassman. The compassman must study the cause of these errors and must not rely too much upon the camp corrections applied by the camp draftsman. In order to get the best results with the aneroid the instru- ment must be handled carefully and intelligently. The errors introduced by changes of conditions must be recognized by the compassman and topographer. Ignorance of all the factors influencing the accuracy of the results of the use of the aneroid will depreciate the value of the map, and this depreciation will not be due to any defect of the instrument itself. Understanding clearly the cause and nature of the errors encountered it is pos- sible to draw some conclusions as to the conditions under which the aneroid is most favorably used and to determine approxi- mately under what conditions the aneroid is an unsuitable in- strument. Conditions Favorable to the Use of the Aneroid. I. The change in slope or topography must be gradual. Ab- The Abney Hand Level. 351 rupt and steep slopes are unfavorable because it has been found that the aneroid is most liable to show instrumental error when there is a sudden change in pressure under which conditions the aneroid is not able to respond as quickly as is required. If there are abrupt changes in elevation and slope the aneroid will act sluggishly and the first reading will not be accurate. The com- passman must wait a few minutes and allow the instrument to settle. Where these abrupt descents and ascents are made fre- quently much time will be lost in waiting for the aneroid to read correctly. Herein lies the objection to the use of the aneroid in rough and rugged country. Where the change in elevation is gradual the instrument adjusts itself to the change in atmospheric pressure while the compassman paces along the line. No time is lost then in waiting for the aneroid to read correctly and large instrumental errors are not so apt to occur. This is the case in uniformly sloping country where the slopes are rounded and the grades are not changed abruptly at definite points. Such country is most favorably adapted to the use of the aneroid. 2. In country where the strips can be run with some speed and where it is possible for the compassman to finish the mile be- tween base line benchmarks within a comparatively short time the aneroid can be used satisfactorily. Frequent comparisons with known elevations will thus compensate the errors in the readings of the aneroid. Wilson on this point says: — "Where the changes in slope are not great and the journey is made with considerable speed and when the time consumed in travel is comparatively short, the aneroid may safely be used for dis- tances as great as three to five miles though in such cases the aneroid may not check out within a contour interval on the next comparison." In smoothly sloping country where the topo- graphy is not broken the compassman can work with greater speed than where the topography is rough and rugged. As a consequence he will be able to compare his aneroid readings with base line benchmarks within short intervals of time. However, the speed with which the compassman can run the strip is not the only factor in determining the working speed of 352 forestry Quarterly. the crew. Topography will influence the speed of the com- passman, and timber cover will determine the speed of the esti- mator. Where there are many species the estimator will work slowly. Where there are only a few species or only one the estimator will work fast. Thus where both topography and timber cover conditions favor speed in the work of the recon- naissance crew as is the case in uniformly sloping Yellow pine country, conditions are very suitable for the use of the aneroid. The strips can be run with speed and frequent comparison with known elevations will correct the errors in the elevations taken along the strip. 3. Weather conditions must be favorable to the use of the aneroid. Wilson states : — "It frequently happens as on the ap- proach of a storm or change from stormy to clear weather that atmospheric pressure will change in a few hours by over an inch. This means an apparent change in elevation at one place of over 1000 feet or more." In winter cruising on the Crater Na- tional Forest the corrections of the great aneroid variations caused by the unsettled weather conditions will introduce errors of over 300 feet in the final corrected results. It has been found almost impossible to correct these big errors caused by the daily weather variation in the winter time. The aneroid is most suit- able only when the weather conditions are settled. The Abney Hand Level. Realizing that the aneroid is liable to introduce errors in the horizontal location of contours when that instrument is used under unfavorable circumstances, the following methods have been outlined in order to substitute a geometric system of ob- taining vertical control. It should be borne in mind, however, that the trigonometric methods here mentioned should not be used with the object of doing work of high precision. The sole aim of the use of these methods is to bring the work of obtain- ing vertical control within the proper limits of accuracy which limits can not be attained with the aneroid under prevailing unfavorable conditions. If these methods of using the Abney are used with a clear conception of the degree of precision to be attained the mapper will not waste time in attempting to do work of too great refinement. The Abney Hand Level. 353 The work in vertical location along the strip is' valuable only to guide the office man in the positioning of the contours upon the form line field sketch turned in by the compassman. Consequently if the field man preserves the general profile of the strip the elevations secured along his line will be accurate enough for all practical purposes of the work. The precise elevations of particu- lar points along the line are of no moment. The relative value of the slopes the one to the other along the line are of intense practical value to the man in the office when plotting the final map. Errors in absolute elevation along the strip line are con- trolled by the precise elevations of the base line stakes at each end of the strip line. In order to handle the Abney intelligently the compassman must clearly understand the theory of the Abney level and its practical application in obtaining elevations along the line on a strip sur- vey. The geometric principle is readily understood; the slope is measured either in degrees or per cents of slope ; the tangent of the vertical angle represents the per cent of slope ; the two are synonymous ; in descending a slope of two per cent the com- passman drops two feet in elevation in every 100 feet of hori- zontal distance. The real difficulties in the use of the Abney are encountered in its practical application. The compassman is too apt to be confused by every little irregularity of the ground. Before at- tempting work with the Abney the compassman must under- stand that the object of his work is to obtain a general profile of the ground along the strip. The final map is drawn on a scale of four inches to the mile. The small irregularities which attract the attention of the compassman are lost sight of in the preparation of the final map. The accurate approximation of the per cents of the slopes along the strip becomes the guide of the office draftsman when he expresses the character of the various felopes by contour lines. Then the value of the slope data be- comes most apparent and the desire for the representation of the minor points of relief is recognized as impractical and unneces- sary. The compass man need not sight upon any definite object. His sight must be largely influenced by judgment and this judgment can be practiced so that the compass man will be able to approxi- _^54 forestry Quarterly. mate the slope of the ground accurately without having definite points of sight. The final resulting profile by this method of sighting will be sufficiently accurate to- be of real practical value in plotting the final map. The errors in profile by this method will never be too large to destroy the value of the work. A profile drawn from eleva- tions taken with an aneroid would at times show glaring errors in slope which errors would be detected at once in the field by the compassman with an instrument based upon a geometric principle such as the Abney. Aneroid reading frequently will show errors of fifty feet in descending an abrupt slope of 200 feet in less than five chains. The compassman must make an all too apparent error with the Abney in order to introduce this same error into his profile. Yet the aneroid reading stands' and the error remains uncorrected by the office corrections applied to re- move the errors caused by weather and temperature changes. The compassman will usually be able to take the sightsi illustrated. Snags and trees are usually found in bodies of dense brush. Furthermore the compassman can obtain the heights of the snags and low trees sighted upon with sufficient accuracy by guess alone. If the situation calls for greater accuracy in the determination of the height of the tree or snag the com- passman can obtain the height of the snag or tree using the Abney as a hypsometer. The compassman should always bear in mind that he is not re- quired to do work of precision. He is' asked to exercise ac- curacy in judgment and to cultivate obtaining practical accuracy in results without paying attention to distracting details. Always bearing in mind the nature of the final map the compassman will be able to recognize the important topographic features and he will lose sight of the insignificant points of relief. Then in tak- ing his sight he will be able to sight parallel to the general slope of the ground or avail himself of other means of sighting as trees, shrubs, etc., to obtain the slope profile. His judgment and ingenuity will improve and speed will come with practice. In order to do accurate work the adjustment of the instrument must be checked before using it. Simple diagrams and instruc- tions are shown in figures i and 2 explaining how to check the adjustment of the level and how to adjust the instrument The Abnev Hand Level. 355 when the same has been found to be out of adjustment. Two methods are illustrated. The first method is the best when it is possible to place two boards or stakes at equal elevations with a „j,,j Tht t»io jtcWl a<^ Tf»t5 at.

If through accident the level is thrown out of adjustment and the crews are in sidecamp where a level or a transit is not available, Method 2 will answer the purpose. A Simple Method of Working imth the Abney Hand Level. This method of keeping field notes is proposed in order to simplify and shorten the work of the compassman. It is recognized 356 Forestry Quarterly. that one of the chief objections to the use of the hand level in reconnaissance is in the matter of speed.

In the first case above described the return on the capital was ample, but the margin over the operating costs was so ridiculously small that no sane logger would attempt the job since the least accident such as a period of bad weather might easily wipe out all profits. In the second case the margin on the operating cost was ample but the return on the money in- vested was insufficient to interest capital. Obviously both de- mands must be met. Neither formula alone can measure both. The investment method, of course, defines absolutely the return to the invested capital, while the operating cost method is an excellent measure of the margin necessary above the cost of operation. Therefore, both should be used, constituting a double minimum. Thus used, the range of percentages in each may be kept reasonably low. With the percentages standardized, the formula which gives the lower profit must govern. This simultaneous use of the two methods brings in question at once the advisability of including interest as a cost in the operating cost method. This practice, which has become al- most universal since its adoption in the Forester's formula, has something in its favor where the investment method is not used as a check. To include interest makes a formula which is in a sense a hybrid between the two methods. Extra profit is allowed in the form of interest for extra invested capital not fairly represented in the operating cost. This compensation is, however, only partial since the interest rate is invariably (and necessarily) low, say 6 per cent, as compared with the profit rate. Further, its inclusion tends to confuse the results. Neither the margin over the real operating costs nor the return on the investment is shown. The profit allowed consists of three factors: i. A percent on the operating costs (which may be earned several times a year). 2. A per cent, per annum of a part of the invested capital, (usually only the fixed investment), and, 3. A per cent (profit) on this last percentage since the latter is carried as a cost item. And these three factors are so confused that analysis is dif- ficult. When both formulae are used, the interest charge should 380 Forestry Quarterly. unquestionably, in the opinion of the writer, be omitted. The necessary return on the capital is obviously shown by the in- vestment method, and, as previously suggested, the straight op- erating cost method is an admirable measure of the margin necessary. The $6.00 logging job involves roughly twice the chance of unforeseen costs as does a $3.00 job, and demands approximately twice the margin. This is not true, however, where interest on invested capital is added as a cost. The same logging chance handled by a railroad instead of by driving may well involve less operating cost but greater invested capital. It is obviously, however, a more stable proposition and can be handled on a lower margin. The decreased operating costs and the correspondingly lower margin necessary should be reflected by the operating cost formulae while the increased capital in- vested can better be expressed and handled by the investment method. While, in general, both formulae are necessary, in certain specific cases it can be seen from inspection that one or the other will give the lower stumpage rate and hence govern. Small sales similar in character to that first described ordinarily in- volve such a small investment that the operating cost method can safely be applied without check. This is a great advantage to the seller of stumpage since appraisal of these small chances must usually be made by men of narrow experience who, while thoroughly competent to estimate logging costs, are somewhat at sea on questions of invested capital. To summarize, it is felt that (i) if stumpage is to be ap- praised by formulae, both the operating cost and the investment methods must be used and the lower stumpage indicated adopted, and (2) that interest on fixed capital invested should not be in- cluded as an operating cost. STANDARDIZATION OF FIRE PLANS, ORGANIZA- TION, EQUIPMENT AND METHODS IN DISTRICT III. By John D. Guthrie. An interesting and productive conference was held at the District Forester's offices' in Albuquerque, N. M. in March, 1914. The Supervisors of the Datil, Coconino, Sitgreaves, Gila, Apache, Pecos and Jemez Forests, with certain of the District officers, acting as a committee, considered the standardization of fire plans, organization, methods and equipment. The desire of the committee was to find out how far the District should go in making the features of the present annual fire plan standard, with the idea of making all instructions of the plan, upon which the committee agreed, as mandatory hereafter for the entire district. It was realized that local conditions had to be considered in any attempt at standardization, yet it was felt that certain pro- visions of the fire plan and certain methods and equipment could well be made uniform for all forests in Arizona and New Mexico. This committee went on record as adopting the following: Discovery of Fires and Method of Reporting. As standard the triangulation system of detection, from pri- mary lookout stations, to be supplemented by riding patrol only on those portions of a forest which cannot be covered from lookout stations. On forests having adequate telephone communication fires will be reported to both the supervisor and district ranger or fire chief. Rank of Officers. It was decided that ordinarily the primary lookout man will rank next in authority to the district ranger or fire chief. No objections, however, will be made if the fire organization is such that patrolmen should outrank lookout men. The im- 382 Forestry Quarterly. portant consideration is that instructions to lookout men and patrolmen must be definite in this matter of rank in order to fix responsibility for action. In the ideal fire organization, pa- trolmen will be essentially fire fighters. Under this heading there was considerable discussion regarding the giving of an appoint- ment as forest guard to lookout men and patrolmen, who might in many cases be excellent men for these positions yet who were not ranger material, and in a way were performing the work of day laborers. Some of the committee held very strongly that no new men should be given a guard's appointment who would not possibly later develop into ranger material, and that all look- out men and patrolmen should be day laborers. As opposed to this view it was pointed out that the Forest Service has em- phasized very strongly that every member of the forest force whether he be supervisor, deputy, forest assistant, ranger or guard is an integral part of the fire organization, and each man must realize a sense of responsibility if results are to be ex- pected, also that there is no more important position in the fire organization than that of lookout man, that the qualifica- tions for the duties required were peculiarly exacting. In view of these facts the point was made that it did not look consistent to consider the lookout man as a mere day laborer, that it could not be expected that his sense of responsibility would be aroused or that he would feel that he was part of the fire organization if he were a day laborer, paid so much per day, and liable to be dropped any day, that by giving him an appointment it would in itself be impressed upon him that he was a forest officer and a part of the fire organization, and that he had certain re- sponsibilities and duties. The statement has been made frequently that the Forest Ser- vice should not give guards' appointments to all men used tem- porarily on the forests ; that a forest guard should be an assistant to a ranger ; that the Service should reserve this title for men who have decided to enter the Service work to become eventually rangers, and that it is not desirable to give men serving in such capacities the power to arrest. It is extremely seldom that the actual power to make arrests is made use of by any forest of- ficer— there is no need of it — and therefore it is not felt that Standardization of fire Plans. 383 that question in itself is worth considering. There are certain men on almost any Forest, who by reason of several summers' experience as guards and of their intimate knowledge of the country and local conditions, make the very best possible guard material. These very often are men who do not intend to be- come rangers, who own ranches and who could not pass the ranger examination if they took it, and others in exactly the same class who are too old to take the ranger examination. These men are glad of the opportunity to earn some money dur- ing the summer, make excellent guards, but would not be willing to work as day laborers at all. The solution of this matter is that there should be special positions of lookout man and patrolman, to be appointed as such. Surely every field forest officer realizes that there is no more responsible nor important position than that of lookout man — then why not recognize it by making a special appoint- ment? Divorcing Protection From Administratton. Until protection can be absolutely divorced from administra- tion, fire plans cannot be considered perfect. On those forests where the administrative work during the fire season is of such a character that it can either be neglected entirely or handled by the district rangers without interference with their protec- tive duties it may be said that the two are now already divorced. On large forests containing extensive stands of timber, the first step to be taken toward divorcing protection from adminis- tration is the establishment of fire units, with the assignment of a fire chief in charge of each unit. Such units will be made without regard to the boundaries of administrative districts. If two or three administrative districts are included in whole or in part in a fire unit, their respective rangers in charge will con- tinue the administrative work and will be called on only in the event they are needed for actual supervision of fire fighting. Un- der this system, the organization for fire protection is separate from the administrative organization until there is a large fire or a number of small fires. This means that a district ranger in charge of an administrative district will not be called upon 384 Forestry Quarterly. until the need for his services has' been indicated by the fire chief or supervisor. Rate of Wages. The maximum wage for inexperienced men as either lookout man or patrolman will not exceed $60.00 per month, together with subsistence, which will not cost over $15 per month; this subsistence to be furnished by the Forest Service. Inexper- ienced patrolmen who will be so situated that there is no necessity for the Service to furnish subsistence will be paid not to exceed $75 per month. Experienced lookout men and patrolmen (those who have rendered one years' service or more and whose services because of their detailed knowledge of local conditions, are in- valuable so that they could not be replaced), may, in the discre- tion of the supervisor, be recommended for a wage greater than $60. The District Forester will be informed of the facts in such cases, and his approval secured in advance. Instructions to Protective Force. Either the supervisor or a competent member of his force specifically designated will, in advance of the fire season, or as soon as the special protective force is on the ground, per- sonally instruct each man as to his duties. This will not take the place of written instructions. This field inspection will give the opportunity to orient protractors. The importance of im- pressing upon each officer the necessity of discipline must not be overlooked. It should be made clear to a lookout man that he must remain at his post until permission for leaving is secured from either the supervisor or the fire chief or district ranger, as the case may be. To relieve the monotony of a lookout man's duties, if it can be arranged without detriment, he can be al- lowed to exchange positions with a patrolman for a week or more; this is to be done only after specific authority has been given. Co-opera^tion. Inter-forest boundaries will be practically disregarded in con- sidering protection against and fighting of fires. On those forests which adjoin Indian Reservations', supervisors will personally take up the matter of co-operative fire protection to ascertain if mutual arrangements can be made. If such ar- Standardization of fire Plans. 385 rangements can not be made, the District Forester will, after being duly informed of the facts, take the matter up with the Forester. The idea, as indicated, will be to work from the bot- tom up rather than vice versa. Supervisors will write to local postmasters calling to their at- tention the matter of co-operation, as indicated in an Order is- sued by the Postmaster General in 1913. Before the beginning of the fire season a circular letter should be sent to each permittee; the letter will be in the nature of an appeal — instructions and commands must be avoided. Cards or posters containing the Six Rules will be given as wide distribu- tion as possible ; fire signs and notices are to be posted in well chosen location, avoiding the "bunching" of them. Large painted fire signs (2x3 or 4 ft.) well placed at the entrance to a Forest or occasionally along a well travelled road should possibly be of greater benefit than a larger number of ordinary signs posted indiscriminately. The fire campaign must at all times be an active one; in so far as possible — following up circulars with personal talks, and preparing fire news items for local papers whenever there is a "lead" for a story. Per Diem Guards. Per diem guards will be appointed on every Forest where the class of men suitable for this position can be secured. They will be considered as a part of the fire organization. Such ap- pointments are conducive to responsibility and quick action in time of fire, where no other forest officer happens to be in the immediate vicinity. The appointment of per diem guards at the rate of $.35 per hour for time actually worked in fighting fire together with the fact that rangers can now act as notaries in administering oaths, should remove any possible objections to the plan. The rates of pay for fire fighters are to be: Laborers, $.25 per hour — maximum; Cooks (regular experienced) $.35 per hour — maximum ; Foremen, $.35 per hour — maximum. Instructions in the time book (form 875), which was sent out in 1913, will be followed in determining the time of fire fighters. Ordinarily the officer in charge of a fire will keep the time of fire fighters. Studying the Efficiency of Lookout Stations. One very important feature of the 1914 fire plan will be the 386 Forestry Quarterly. thorough study by the supervisor or a competent forest officer whom he may designate, of the efficiency of lookout points, be- fore new points are selected and towers erected. Generally it may be said that every forest has a few prominent peaks and they have been selected as lookout stations as a rule. What is wanted is to know accurately whether these points already se- lected really cover the areas they are supposed to. To deter- mine this, go to a lookout point and take bearings on all prom- inent points in the area covered by the lookout, as well as bear- ings in canyons and on natural boundary features, making an estimate of the distance to all such points and plot them on the map so that a meander line can be drawn around the "seen" area. Where nearby ridges or other small peaks are so located as to interfere with fires on their far sides being readily discovered, special note should be made of these con- ditions, so that they can be checked from other lookout points. If after checking the area of efficiency of all lookout points, it is found that there are certain areas that can not be seen from any of them, the advisability of establishing another primary lookout or, if none is available, the location of a patrolman's route will be in order. Fire Maps. The present fire map, a sample of which was sent out in the spring of 1912, has been adopted as the standard fire pro- tection map for the district. This means the adoption of all the information as given on that map. When there is a riding patrol the routes of patrol will be indicated. The organiza- tion diagram will be placed on the map. The protractor should be drawn directly on the tracing at each primary lookout point. On the forests where the tri-colored base map is now in use or where there is any reason for not placing the protractor on the tracing, the transparent protractor will be pasted on the map. Where there are inter-forest primary lookout points, a double arc, with the projected bearings from the lookout point of an adjoining forest marked on each arc, should be on the border of the map, so that a correct bearing may be had from the lookout point of such adjoining Forest. In order to get this it will be necessary to give each Forest its proper location with Standardisation of Fire Plans. 387 regard to adjoining forest maps and strike a circle with a radius long enough to reach from the exact location of the look- out point to the border of the map. Maps of inter-forest areas comprising a fire protection unit will be prepared as rapidly as possible. Report Forms — Equipment and Supplies. A blank form to be used by lookout and patrolmen as a daily report was adopted for general use ; likewise a blank report form to be used by the supervisor, fire chief or district ranger in recording the daily reports from the lookout and patrolman was adopted. On Forests inadequately provided with telephone communication, where the so-called mail box system is used for checking the work of patrolmen, a suitable galvanized iron box was adopted, as well as a blank form for the purpose of record- ing the visits of lookout men. Standard supply lists will be left with each store-keeper living in or near the Forest and necessary arrangements made so that he can send immediately when requested the supplies specified in the list. The standardization of subsistence supplies for fire fighters was thoroughly considered, but no list adopted, due ap- parently to the great variation in local conditions. With the intent of avoiding possible criticism or comparisons between adjacent Forests', the following list of food supplies, when supplied by the Forest Service to lookout or patrolmen was adopted as standard: Beans Fresh meat Flour Coffee Baking soda Lard Dried fruit Tea Pepper Salt Canned milk Bacon Canned tomatoes Sugar and syrup or jam Canned corn or peas I'-lacaroni and rice Baking powder Potatoes It was felt that the above list gives sufficient opportunity for selecting a diet that can be relished by the most fastidious employee. The total cost of supplies that may be purchased 388 Forestry Quarterly, from this list for one man for one month will not exceed $15.00. The, following equipment for a lookout station was made standard : The fire maps ; A metal protractor 14 inches in di- ameter; A metal sight alidade 14 inches long, with a pointer on one end, and hole in center to fasten in center of protractor. The sights will be at least 6 inches high. Where needed a lookout watch-box, or shelter, is to be con- structed. The telephone installed on the tower, and if pos- sible a second one installed on the ground or in the lookout's cabin, which must be as near as possible and convenient to the lookout point or tower. The tools will be a rake, axe, shovel, and saw. In reference to the type of telephone to be used in enclosed towers of lookout shelters, considerable discussion did not re- sult in standardization. Some favored the adoption of desk setb or regular wall sets, while others believed the use of the metal box telephones should be continued. Standard equipment for a patrolman will be as follows : i axe ; 1 shovel, hoe or rake, with handle ; Emergency rations ; Instruc- tions in writing; Forest Service key, at the discretion of the supervisor. An upright galvanized metal tool box was adopted. This box is very stoutly made, knock-down style, 27 inches wide and 30 inches deep and 8 feet tall. The door is 4 feet 10 inches tall by 2 feet 4 inches wide, and the bottom of the door is 16 inches from the base of the box. There are two racks inside on the back wall for holding rakes, shovels, axes, etc., and on each side a shelf for storing canteens, water bags, etc. The space in the bottom will hold food supplies, pack outfits and other fire box equipment. The box is water and rodent proof. On the inside of the door of the box will be posted a list of the tools in it — a duplicate of this list will be kept in the ranger's ofifice, and also in the supervisor's office, if desired. A standard list of tools for boxes was considered, but not deemed advisable. There should be a rodent-proof box at all places where a reserve food supply is kept. This should be made of galvanized metal similar to the tool box. Pack train outfits will be kept at strategic points for the purpose of bringing in supplies to fire fighters, if in the judg- ment of the supervisor such outfits are needed for efficient pro- Standardisation of Fire Plans. 389 tection. Before purchasing burros, mules or horses for this purpose the approval of the District Forester is necessary. Use of Improvement Crews. Wherever it is possible to do so, improvement crews during the fire season should be placed on w^ork where they can be avail- able for fire jighting, thus giving an additional reserve supply of fighters in case they are needed. The foreman will have a wagon and team, or some other means of transportation, and will be equipped with a portable telephone and enough emergency wire to conveniently reach the telephone system. In case of fire he will be called on to go to it immediately, with his crew if necessary. Awards. The committee decided that the plan of making awards should be tried out this season. These are to be given to Forests hav- ing at the end of the fire season the best record in fire protec- tion. A first and second prize will be given. The award will consist of a framed official letter for posting at the Forest head- quarters, designating the winning Forest, together with a list of the entire Forest personnel, copies of the letter being sent to each member of the Forest force as well. The first prize will be designated by a blue ribbon attached to the letter; the sec- ond by a red ribbon. The awards will be determined on: i. highest percentage of class A fires; (2) smallest average acreage per fire, including all classes of fires; (3) inspection reports Inspection. The committee went on record to the effect that it is of the first importance for the supervisor himself to personally in- spect the workings of the protective plans in the field. Monthly field plans for the supervisor's office force must provide for this during the fire season and will be scrutinized by members of the District Office with this end in view. The committee fully discussed the following, but did not feel at that time that standardization was practicable; pack saddles and outfits; nested cooking equipment; water packing outfits for use on pack animals ; electric storage battery ; lanterns for tool boxes. A COMPARATIVE STUDY OF TWO LOG RULES, AS APPLIED TO TIMBER IN CENTRAL NEW YORK. By John Bentley, Jr. It is a well known fact that there are a great many log rules in use in different parts of the country, and that the values given in these rules vary within wide limits even for logs of the same size. Differences of 25% or more are not uncommon in logs of the smaller diameters, and while the relative differences in logs of large diameter are not so great, the absolute differences are sufficient to cause one to marvel that the same log could by any chance yield such uncertain quantities of lumber. The factors influencing the board foot contents of logs are, of course, numer- ous ; but with sound logs and a definite allowance for saw-kerf, it seems that any log rule constructed on sound principles should be able to stand comparison with the actual mill cut of a num- ber of representative logs. That the same log, when scaled by the Doyle rule should yield only 16 board feet, and when scaled by the Scribner rule should yield 32 board feet seems absurd, and yet these are the figures assigned by these two rules for a log sixteen feet long and 8 inches in diameter. If the differences were fairly constant, one might feel inclined to excuse such dis- crepancies on the ground that saw-kerf and slabs were allowed for in different degrees ; but when one follows these same two rules to a log 48 inches in diameter, and finds the relative posi- tions just reversed, — that by the Doyle rule the log contains 1936 board feet, and by the Scribner rule 1728 board feet, it then be- comes obvious that the rules can not both of them be con- structed on sound principles. What are we to do? What, in particular, is the man to do who is not familiar with the in- consistencies of log rules ? Some people may even be buying by one rule and selling by another rule, ignorant of the fact that there may be a difference of from 10 to 20 per cent. It has long been the desire of the writer to test the accuracy of the "Universal" Log Rule, devised by Prof A. L. Daniels, of the University of Vermont, and published by him in Bulletin No. 102 of the Vermont Agricultural Experiment Station, in A Comparative Study of Log Rules. 391 1903.* This rule appeared to be based on principles entirely sound ; and when compared with other rules, it seemed to have escaped the errors which are often so noticeable. It was de- cided, therefore, to test the "Universal" Rule in a way which would prove its accuracy when applied to logs of various dimen- sions, and afford a comparison with some other rule in com- mon use. The opportunity came when a small portable mill was found in operation not far from Ithaca. Three students* were assigned to a study involving a test of the "Universal" Rule and the Scrib- ner Rule. The method consisted in scaling numbered sound logs of different sizes by both log rules, and then comparing these results with the actual product of those same logs, when measured as lumber. In this way it was possible to discover whether the differences were constant, and if so in what degree, so that some definite conclusions could be drawn as to the relative accuracy of the rules when compared with the mill- cut. While it might be argued by some that a portable saw- mill hardly affords ideal conditions under which to study a problem of this nature, let it be said that the logs that are bought and sold in New York state to-day are more likely to be sawed at a portable mill than at a large stationary mill. The day of big lumbering operations in New York, except for a few in the Adirondack Mountains, is past. A great deal of work in other sections of the state, where woodlots rather than large forests are the rule, is done by portable saw-mills. And they are operating in some remarkably good pieces of timber, woodlots that have been protected and preserved for two gen- erations or more, where stands of 25,000 feet, B. M., per acre are occasionally met with.* In the case now under consideration, the mill was a small one, with a 52-inch rotary saw cutting a kerf of ^ inch. The logs were mostly White Pine and Hemlock, although a few hardwoods were also included. The logs were sawed into inch- boards or two-inch planks, the proportion of the latter being ap- * See also Forestry Quarterly, Vol. Ill, p. 339. *Messrs. H. B. Steer, C. S. Hahn and P. C. King. *The stand per acre in the present instance averaged 25,000 bd. ft. The writer knows of one acre of nearly pure pine in New York State, that was cut a few years ago, yielding 50,000 bd. ft. 392 Forestry Quarterly. proximately 30%. While leaving some things to be desired in the way of equipment and efficiency, the operation was typical of much of the work being done by the portable saw-mills in the state. The number of logs scaled and measured was 62, of which ^4 were White Pine, 21 Hemlock, and 7 hardwoods. They .anged in size from 8 to 16 feet in length, and from 6 to 28 inches in diameter. The smallest log scaled and sawed was 8 feet long md 6 inches in diameter. The largest log scaled and sawed was iO feet long and 28 inches in diameter. Each log was scaled by both the "Universal" Rule and the Scribner Rule, and a tally kept of the actual product, measured as it came from the saw. The logs were divided into seven groups, based on the amount of lumber indicated in the scale, as follows : Group I, included all logs scaling from i to 50 board feet; Group II, included all logs scaling from 51 to 100 board feet; Group III, included all logs scaling from loi to 150 board feet; and so on, Group VII, including all logs scaling more than 300 board feet. (Table 2 shows the number of logs in each group.) Table i is a summary of the results, showing only the amount of the over-run in board feet, and expressed as a percentage. This table shows the "Universal" rule to approach quite closely to the actual mill cut. Table 2 shows in more detail, just how the over-run was distributed, according to the size of the log. This Table is very instructive in respect to the fact that the greatest percentage of over-run, in both rules, occurs in the logs of small diameters. This would indicate that the rules are inaccurate for the very small logs, and since in any "run" of logs there must always be more small ones than large ones, this ten- dency of log rules to undervalue the small logs should be re- membered. In the larger sizes, particularly from 16 inches in diameter to 26 inches in diameter, the differences noted are not so great. In this connection, it is interesting to note that a sound log 10 feet long, and 28 inches in diameter, scaled 364 board feet by the "Universal" Rule, 360 board feet by the Scrib- ner Rule, and the measured lumber from this log amounted to just 364 board feet. It would seem, therefore, that our log rules, — most of them — are not liberal enough with the small logs, and in these days of close utilization, the small logs may often count for a good deal, in the aggregate. A Comparative Study of Log Rules. 793 Table 3, showing the mean over-run in board feet for logs of the several groups, discloses the fact that the Scribner rule is less reliable than the "Universal." The mean over-run for the Scribner is about double that of the ''Universal" in all groups excepting Groups V and VII. This confirms the figures shown in Table i, where the percentage of over-run on all logs is nearly in the same proportion for the two rules. It is acknowledged that in a study of this kind there is some opportunity for the lack of skill on the part of the scaler in dis- counting for defects to affect the figures to such an extent that no definite conclusions could be reached. If the full scale were allowed on defective logs, then the mill-cut would be quite likely to fall short of the scale, and conversely, if too liberal a discount were made the mill-cut would greatly exceed the scale. In the present instance the conditions were favorable to a high degree of accuracy, because the logs were most of them sound, and the task of scaling called for the exercise of judgment chiefly in the matter of determining the average diameter, and proper al- lowances for slight crooks in the logs. The general conclusions reached in this comparative study of the two log rules may be stated as follows : (i) Both the Scribner and the "Universal" Rules give a sound log less than can be produced from it under favorable con- ditions. (2) Both rules fall short by larger percentages in the small logs than in the large logs. The scales apply with the greatest accuracy in logs of medium size, that is, from 16 to 26 inches in diameter. (3) With sound logs, the mill-cut may be expected to over- run the Scribner scale by about 10% and to over-run the "Uni- versal" scale by about 5%. (4) All things considered, the "Universal" Rule will give bet- ter results than the Scribner Rule, but both run low for the logs of small diameters. Note. — The "International" Rule, as printed by Dr. J. F. Clark in "Forestry Quarterly," Vol. IV, page 79, may be adapted to allow for a saw kerf of % inch by applying a reducing factor of 9.5%. This was done, and the logs by this scale would yield a total of 7,435 board feet, or only 2^% less than the actual mill cut. It may be said, therefore, that the "International" Rule, when adjusted to allow the proper amount for saw-kerf, will undoubtedly give very good results. 394 Forestry Quarterly. TABLE I.

B3; Wm. W. W. Colton. The Younglove Log Rule is mentioned in the Woodsman Hand- book and also in Graves' Forest Mensuration, but the author states that he was unable to obtain the rule and could find out very little about it. Consequently, when a few months ago I was looking in a local hardware store for a caliper to measure logs with, I was rather surprised to find that the only one in stock was a Younglove Scale Caliper. Upon making inquiries, I discovered that the Younglove Rule had at one time been the only one in use in this section of the State (Fitchburg, Mass.) and that even up to the present time saw mill owners and people selling logs throughout this locality claim that the Younglove Rule is the only one to be used. As there was so little known about this rule, I thought it might be of interest to others to learn more about it and I have therefore sought out the following information. The Younglove Rule was originated by Tyler Younglove, who was born in Fitchburg about 1812. He was a carpenter by trade and worked for many years in a local saw mill and lumber yard. About 1840 he worked out this rule and in later years, together with his son, manufactured calipers and sticks for measuring sawed lumber. After his death, his son conducted the business enlarging it to some extent and made scale sticks and calipers of all kinds. He died a few years ago, and with him died the secret of his log rule. A grandson of Tyler Younglove, Mr. Wm. K. Younglove, is now a captain in the Fire Depart- ment in Fitchburg, and through his courtesy I was allowed to look over the papers and other effects of his late father and grandfather. Among these, I ran across one copy of the mill table for log measure which is in my possession. No record, however, could be found of the principle upon which the scale was made. I have talked with a number of old residents who knew the old gentlemen in life, and the general opinion is that the table was constructed from diagrams and from actual meas- urements of logs at the mill. In comparing it with the other 396 Forestry Quarterly. tables given in the Woodsman Handbook, I find it corresponds very closely to the Baxter Rule. For logs over 20" in diameter, the contents of logs given is slightly less than in the Baxter Rule. By applying Prof. Daniel's Method given on page 34 of Graves' Forest Mensuration, we find the formulae for this table to be V=f D^-f 9/20 D— 7. According to Mr. Wm. Younglove, his father would never im- part the secret of making this to anyone, and often boasted that it would die with him. Since his death, there have been no more Younglove Calipers made, and I believe at the present time I have in my possession the last one ever placed on the mar- ket for sale. From those who have used this rule, I find that the best results are obtained from taking the diameter outside the bark at the small end of the log. I have used the caliper myself this year in measuring logs, cut from a small woodlot near by, and have taken measurements both at the small end, and one third of the way from the small end. These logs have been marked and I hope to follow them through the mill at some later date to see which measurements tally up the best. It would seem that the table would give very fair results for the measurement of small diameters but runs rather low for dia- meters above 24 inches. (The logscale itself was submitted, but is not printed for lack of practical interest. — Ed.) PROGRESS OF THE U. S. FOREST SERVICE. AS REFLECTED IN THE FORESTER'S REPORTS FOR 191 1, 1912, 1913. By Alexander J. Jaenicke. Any one familiar with these annual reports will realize that it is impossible to adequately give an idea of their contents in a brief abstract such as this purports to be. An annual report con- cerns itself with the activity and the plans of the U. S. Forest Service, and this is discussed in an exceedingly concise and not at all detailed manner. An abstract, therefore, must necessarily omit much that is exceedingly important; in fact, nothing but a general idea of the contents can be given. The report for 191 1 is really Mr. Graves' first report, the 1910 Report being the last one of Mr. Pinchot's' administration. In abstracting ]\Ir. Graves' reports for 191 1, 1912 and 1913, it was thought best to consider them together rather than separately in order that the growth and progress of the Forest Service during these three years could more easily be traced. In the following pages, when the year 191 1 is mentioned, this will mean the fiscal year 191 1, or the period between July i, 1910 and June 30, 191 1 and similarly for the other years. All three reports are much alike as' regards the order in which the various topics are taken up, and this sequence will be followed in this brief, the main topics being indicated by headings. Classification of Expenditures and Receipts. For the years 191 1, 1912 and 1913, the annual expenditures of the Forest Service have been between $5,000,000 and $6,000,000. Thus these years have seen no marked rise in the annual appro- priations. Under the heading of salaries and general expenses, over 90% of the annual appropriation was used each year, less than 10% being used for the permanent improvement of the National Forests. Consequently the administration and protec- tion of the National Forests has cost an annual average of 2-| cents per acre while the improvements have amounted to less than 2^ mills' per annum. The receipts of the Forest Service can be classified under the following three heads: 398 Forestry Quarterly. 1. Timber. 2. Grazing. 3. Special uses. In 191 1, the total of these receipts amounted to slightly over $2,000,000. In 1912, there was an increase of $100,000 and by 1913 the total annual receipts were practically $2,500,000. The average distribution of these receipts is roughly about as follows :' Timber— 55 %—$ i ,350,000. Grazing — 40% — $1 ,000,000. Special uses — 5% — $150,000. In the future, there is no doubt but what the receipts from timber will show the greatest increase, although steady gains in grazing and special use receipts can be confidently looked for. Organization and Personnel. Perhaps the most noteworthy of mention here is the tendency toward the reduction of supervisory officers in Washington and in the districts. The officers in Washington were decreased by placing increased responsibility upon the district officers, and these in turn were reduced in number by gradually increasing the responsibilities of the supervisors. In addition, during Mr. Graves' regime, there has been much attention paid to the organization of the protective force and the investigative work. There has been a marked increase in ef- ficiency in both as' a result of this re-organization. The classification of the forest force at end of the year 1912 was as follows: Supervisors, 147 Deputy supervisors, 9^ Rangers, 1393 Guards, 7^ Forest examiners and forest assistants, 156 Clerks', 171 Miscellaneous lumber men, experts, hunters, etc., • 15^ Total, 2895 Progress of the U. S. Forest Service. 399 The previous year the Forest Service numbered 2624 men. These figures are indicative of the very gradual increase which may be expected in the future, in contrast to the rapid increases in the earher history of the Service. Area and Boundaries of the National Forests. During the past three fiscal years, the area of the National Forests has remained practically the same, amounting to ap- proximately 187,500,000 acres at end of the fiscal year 1912, in- clusive of Alaska. Exclusive of Alaska and Porto Rico, the National Forests at the end of 1912 included roughly 160,600,000 acres. This area is distributed in approximately 160 National Forests, a National Forest thus averaging slightly over one mil- lion acres. Exclusive of the acquisitions under the Weeks Bill, National Forests exist in 20 states, California leads in the area of National Forests within its borders with almost 28,000,000 acres. Idaho and Montana follow closely with almost 20,000,000 acres in each of these two states. The policy which has governed recommendations for additions and eliminations since the fiscal year 191 1, may be briefed as follows : Lands to be retained within the National Forests: 1. Lands wholly or partly covered with brush which are valu- able for watershed protection, or open land on which trees may be grown, unless their permanent value is greater for cultivation than for protection. 2. Lands wholly or partly covered with timber and under- growth which are more valuable for growing of trees than for agriculture. 3. Lands not possessing timber or brush which should be in- cluded in National Forests for administrative reasons. Lands to be eliminated from National Forests: I. Lands not wholly or partly covered with timber or under- growth upon which it is not expected to grow trees. Claims and Settlements on the National Forests. The claims on the National Forests may be divided into two large classes : i. Homestead claims. 2. Mining claims. 400 Forestry Quarterly. Claims within the National Forests are constantly the source of much annoyance and trouble because of the frequent attempts at fraud. During the fiscal year 1913, 1,690 individual tracts of land in the National Forests' passed into private ownership through the patenting of claims. These included: Homestead claims, 977 Desert land claims, 6 Timber, stone claims, 35 Mineral claims, 639 Coal claims, 24 Miscellaneous claims, 5 In 191 1, this total was almost 3CXX), while in 1912, it had dropped to 1500. There are several reasons for this, but they cannot be discussed here. Suffice it to say, that the criticism that the Forest Service hinders homesteading and prospecting is un- just, and not substantiated by facts. Those who have been foiled in attempts to patent fraudulent claims have naturally been the chief opponents of the present "claim policy" on the National Forests. Land Classification. This work was seriously inaugurated in 1909, but the work has seen its greatest development since the fiscal year 191 2, because of previous experience gained, and the increased appropriations. The purpose of the work in Mr. Graves' own words is "to segre- gate and make available for the establishment and development of homes, all National Forest land which will serve its best pur- pose by being brought under cultivation." In general the work includes the following: 1. Classification of areas where the amount of land chiefly valu- able for agriculture warrants large eliminations. 2. Detailed classification of considerable areas. 3. Examination and classification of single scattered tracts for which prospective settlers make application. Timber Sales. The total stand of timber on the National Forests inclusive of Alaska is approximately 600,000,000,000 board feet. Of this Progress of the U. S. forest Service. 401 about 350 billion feet is overmature and mature. The annual yield is roughly estimated at slightly over 6 billion feet. With the proper deduction for local requirements near the various National Forests, over 5-^ billion feet are available for timber sales to supply the general market. Timber sales are rapidly increasing. Comparison of the fiscal years 1912 and 1913 brings this out clearly: Year. Total sales (ft. b. m.) Stumpage Value 1912, 800,000,000 $1,600,000 1913, 2,000,000,000 $4,500,000 The aims of the National Forest Timber policy may be sum- marized as follows : — 1. Prevent losses by fire. 2. Utilize ripe timber in such a manner as to insure restocking of the land and continuance of production, 3. Sell timber at the proper price. 4. Sell ripe timber so as to prevent speculation. 5. Prevent monopoly of public timber and maintain competi- tive conditions in the lumber industry by its sale. 6. Provide for requirements of local communities and settlers. 7. Make timbered lands of agricultural value available for proper settlement and use. 8. Make the National Forests self-sustaining, and yield revenue to the various states to offset loss in taxes. The most important factors influencing the sale of timber are: 1. Distance of larger bodies of N. F. timber from markets and transportation facilities. 2. Condition of the lumber markets. 3. Difficulties in logging — topography exceedingly rough on many portions of the National Forests. 4. Presence of privately owned timber tributary to same markets as National Forest timber. The relative importance of these four factors vary from year to year, an4 their fluctuation results in corresponding changes in timber sale receipts. A brief classification of the timber sales by years will clearly show their rapid growth in total values : — 402 / forestry Quarterly. Less than Year $ioo $ioo-$500 VALUE. $5oo-$iooo $iooo-$50oo Over $5000 Total. 191 1 5144 327 1912 5279 378 1913 5696 209 70 73 78 . 92 7Z 142 Protection. 39 45 62 5653 5772 6182 Fire losses are reported by calendar years, and not by fiscal years. The calendar year 1910 was an exceptional one for severity, and especially to be regretted is the large loss of life which took place in the fight against the fires. The following summary will give a general idea of the acreage burned over on the National Forests during the past three years for which figures are available : Calendar Year. Timbered Area per locx) Acres. 1910 19.90 191 1 1.78 1912 0.91 Lightning, railroads and campers cause almost two-thirds of the fires which occur. Half of the discovered fires burned over much less than an acre, 25% burn over between 0.25-10 acres, and the remaining 25% burn over more than 10 acres. About 3000 fires are annually fought on the National Forests. It is difficult to get at the exact cost of fighting these fires, since the time spent on them by regular forest officers is not considered in the annual reports. The present efficiency in the protective work of the Forest Service is due to : 1. The rapid development of permanent improvements such as' telephones, look-out stations, etc. 2. Preparation of detailed fire-protection plans on a large num- ber of forests and their rigid execution. 3. Co-operation of private owners and railroads. Aside from protection from fire — there are also the following phases of the protection problem : Progress of the U. S. Forest Service. 403 1. Protection against pollution of streams. 2. Prevention of insect depredations. 3. Control of forest-tree diseases. Reforestation. It is estimated that there are 7,500,000 acres on the National Forests which must be reforested by artificial means. In ad- dition to this, the natural regeneration on 1,000,000 acres cut over annually by timber sales must be taken care of. A great deal of the work of reforestation is still in the ex- perimental stage, and hence in many sections of the country, extensive and expensive plantations are not yet justifiable — dis- trict 3 and district 5 are examples of this. In 1912, the following tentative distribution among the dis- tricts of the area to be reforested annually was agreed upon : — District Acreage 1 9000 2 6000 3 500 4 6000 5 500 6 9000 Direct seeding, under which the tree seed, is sown upon the ground with or without simple forms of cultivation, and the growing of seedlings' in nurseries under ideal conditions to be transported into the field when of suitable size — these are the two general methods used in reforestation work in the Forest Service. In the matter of direct seeding, three problems are con- fronted, i. e. : I. Seed supply. 2. Rodent injury. 3. Cheap culti- vation. In 1913, the reforestation work covered approximately 30,000 acres. About 24,000 acres was sown at an average cost of $4 per acre — 6000 acres planted at $1 1 per acre. Most of the seed used was collected by Forest officers. In 1913, 40,000 lbs. of coniferous seed was collected at an average cost of $.78 per lb. The nursery stock used was obtained from the various forest nurseries on the National Forests. The cost of seedlings in 1913 404 Forestry Quarterly. was $3 per looo, and $5 for transplants. These figures will un- doubtedly be materially reduced in the future. Of the 30,ocx5 acres reforested in 1913, the following is the species distribution : Species Acreage Douglas fir, 10,000 Western Yellow pine, 7,000 Western White pine, 7,000 Lodgepole, 2,000 Miscellaneous, 4,000 30,000 acres. The most notable thing in connection with the reforestation work, is the rapid decrease of per acre costs from year to year, and the increasing success of the work. The experimental work in connection with reforestation is still, however, of first im- portance. Range Management. Over 20,000,000 head of stock are partially dependent on the National Forests for forage. The system of range control de- vised and placed in operation by the Forest Service has won the approval of the vast majority of the western stock growers. To further increase the efficiency of this system, the following studies are under way : — 1. Exact character and condition of all forest lands. 2. Distribution and economic importance of all the herbaceous plants. 3. Natural, artificial methods of reseeding valuable herbaceous plants. 4. Most efficient methods of handling live stock to conserve the range. 5. Character and extent of damage by stock to forests, water- sheds, and methods of minimizing these injuries. A study of the number of stock grazed under permit, shows a gradual increase in the carrying capacity of many forests. This is due to: — 1. Increased forage production. 2. Better knowledge of the ranges'. Progress of the U. S. Forest Service. 405 3. Improvements in handling stock. 4. Better distribution of stock. 5. Gradual substitution of shipping by railroad for trailing. Some of the notable things which indirectly contribute to the success of the present grazing policy of the Forest Service include: — 1. Protection against disease. 2. Protection against wild animals. 3. Prairie dog extermination. 4. Protection against poisonous plants. 5. Co-operation of Forest Service with live-stock associations. Water-power Development. In spite of the fact that the regulations make it impossible to grant permits for a term of years, power development on the National Forests is rapidly increasing. It is estimated that at least 12,000,000 horse power can be developed on the National Forests from natural stream flow. This can of course be greatly increased by storage reservoirs. To again quote Mr. Graves, "The purpose of the administration of the water power sites on the National Forests is to encourage power development in every way possible, while safeguarding the interests of the using public." Since water-power development in the National Forests has aroused so much discussion recently, it may be well to summarize the main features of the Forest Service policy with respect to this development: — 1. The speculative holding of the power sites is prevented. 2. Provision is made for complete and prompt development together with continuous operation. 3. A return is secured for the power site privilege. 4. Permittees are required to abide by certain regulations. 5. The capitalization of the value of the privileges conferred by the permit is prohibited. 6. Sufficient power is retained by the Forest Service so that the placing of unjust burden on the consuming public is prevented. Permanent Improvements. The chief improvements carried on by the Forest Service on 4o6 Forestry Quarterly. the National Forests include roads, fire lines, telephone lines, trails, bridges, fences and buildings. By the end of the fiscal year 1913, these improvements had a value of almost $3,500,000. Ten per cent of the receipts of the National Forests are de- voted to the building of roads primarily for the benefit of the public. In addition to this, 25 per cent of the gross receipts of the National Forests reverts to the states for the benefit of county schools and roads. In the fiscal years 1913 and 1914, the ten per cent item will have amounted to considerably over $200,000 per annum, w^hile the 25^ item v^ill mean an annual $500,000 for the present fiscal year. Acquisition of Lands Under the Week's Bill. Up to the end of the fiscal year 1913, the National Forest Reservation Commission approved for purchase a total of slightly over 700,000 acres. These lands are located in 14 purchase areas in the Southern Appalachians and White Mountains. The states in which these lands are located are: Maine, New Hampshire, Maryland, Virginia, West Virginia, North Carolina, South Caro- lina, Tennessee and Georgia. The work of the Forest Service in fire protection in these pur- chase areas has already resulted in a great improvement in the local sentiment on the forest fire question. Improvement work on these lands has already been begun. Most of the land which has been bought is in a cut-over or culled condition and in many cases only the inferior species are left. Plans have already been made for the management of these areas, especial attention having been given to the grazing busi- ness and special permits, as well as to the timber sale business and the proper restoration of the areas. Co-operaiion With States. The Weeks Law which began its operation on March i, 191 1 with an original appropriation of $200,000 to be expended in the various states with a limit of $10,000 in any one state in any one year has been productive of much good. Among the benefits which have resulted because of this' co-operation are: — I. The shaping of forest policies and forest legislation in vari- ous states. Progress of the U. S. Forest Service. 407 2. Increased activity of the public and the legislatures in the forestry movement. 3. Increased efficiency in all lines of forestry work in the vari- ous states because of the interchange of ideas on effective methods of State organization and fire control. National Forest Investigations. At present there are nine forest experiment stations. Re- forestation problems are given the most attention. The following phases of reforestation are given the greatest attention : — 1. Methods of seed extraction. 2. Methods of direct seeding. 3. Nursery work. 4. Methods of field planting. 5. Studies in the breeding. 6. Factors governing production fertility of tree seed. In addition, mensuration studies, thinning experiments, studies in forest management, forest influences, efforts of grazing, are only a few of the things to which the experiment stations devote their attention. Silvicultural and dendrological studies are carried on by the Washington investigative force. Other studies given consideration by the Forest Service are those that deal directly with forest products. Among these studies are : — 1. Utilization of National Forest timber. 2. Wood preservation. 3. Wood chemistry and distillation. 4. Timber physics. 5. Pulp and paper investigations. 6. Industrial investigations. Conclusion. In this abstract, as little attention as possible has been given to mere figures and statistics. It was deemed far more important by the writer to outline the scope of the work of the Forest Serv- ice, and to give briefly the policies which govern this work. Much that is essential and important had to be omitted in order to give this digest the brevity that is demanded of it. EXPLOITATION OF CROSSTIES IN NORTHERN NEW MEXICO.* By Clarence F. Korstian. The following data on the various operations in the exploita- tion of crossties is based on the methods employed by a company which has been operating for the past six years in Northern New Mexico. The area which is now being exploited lies on the west slope of the Sangre de Christo Range, at elevations of 8,ocxD to 11,000 feet above sea level. The lower slopes of these moun- tains merge into rolling hills and gently sloping mesas. The up- per portion of this area is quite rugged, consisting of deep can- yons which have steep slopes. Mostly the timber is found on the mesas, slopes and ridges. The soil is usually of sufficient depth to cover the underlying rock so that it does not interfere with logging to any great extent. Heivn Ties — Woods to River. The following species suitable for hewn ties are found in this locality: Western Yellow pine (Pinus ponderosa), Douglas fir (Pseudotsuga taxifolia), White fir {Abies concolor), Engle- mann spruce (Picea engelmanni), Alpine fir (Abies lasiocarpa), and Limber pine {Pinus flexiUs). Western yellow pine, Douglas fir, and white fir are the most important species on the area now being cut. The following defects were found common to Western Yellow pine: stump and heart rot, cat-faces, mistletoe and injury caused by the pine bark-beetle. The cat-faces were caused by fires, oc- curring from 25 to as much as 100 years ago, and by removal of the inner bark for food by Indians, a custom which has been discontinued but which seems to have been prevalent 25 to 50 years ago. Trees having stump rot and cat-faces require long- butting which not only increases the waste but results in a lower grade of ties. Mistletoe and the bark-beetle cause the trees to * The writer is indebted to Assistant Forest Ranger Wayne Russel for assistance in collecting the data contained in this article. Crossties in Northern New Mexico, 409 become pitchy and burly, which renders them difficult to work. Generally, however, Western Yellow pine is not difficult to work but is heavy to haul. Douglas fir is usually sound, being the least defective of the species used for ties. It makes the most desirable ties because of its durability and lightness, but is not liked by the majority of tie makers because of its hardness. White fir is very soft and easy to work, and for this reason is preferred by any of the tie makers. It is often seriously infected with stump and heart rot. The policy of seldom marking White fir above 18 to 20 inches D. B. H. has been adopted for this locality, because trees above this diameter usually show considerable rot, White fir makes the least desirable tie because the wood is soft. brittle, and does not hold the spikes firmly. When creosoted it makes a fairly satisfactory tie as evidenced by the fact that the railroad company, in this section of the country, accepts white fir ties together with those of the other species without discrimi- nation. Trees from 10 to 16 inches D. B. H. are suitable for hewn ties, although the tie makers prefer those from 11 to 13 inches D. B. H. At the lower elevations where cutting is now in progress the trees average 2.7 ties per tree. This figure is kept rather low, due to the marking for cutting of all suppressed and defective trees, from which at least one tie can be made, and the short-boled timber toward the lower limit of the Yellow pine type. Three classes of hewn ties are made; squares, firsts, and seconds'. The butts of large trees are made into square ties, which are not less than 10 inches on the face, and do not exceed 8 inches in thickness and 8 feet long. First class ties are 8 inches wide, 7 inches thick, and 8 feet long. Only one inch increase is allowed in thickness or length. vSecond class ties must be 7 inches thick, so long as the log is large enough to permit, and under no circumstances less than 6 inches thick and 6 inches wide. No ties under 6 inches by 6 inches, or over 11 inches by 8 inches, are accepted by the tie inspector. The company's agreements with all of their tie makers contain a stipulation which states that all timber of the proper size for hewn ties must be cut and if sound shall be made into ties. It not sound, it must be cut into every four feet sufficiently to show the defect. All ties must be smooth and of uniform width and 4IO Forestry Quarterly. thickness'. The specifications further state that all ties must be free from shake, loose knots, rot, score hacks, and bark. The per cent of the different classes, according to the past season's cut, is approximately as follows : — Class Per Cent Squares, 8.3 Firsts, 35.8 Seconds, 52.7 Drys (made from dead timber), .6 Culls, 2.6 Total loo.o Making. Areas are allotted to the contractors who in turn subdivide them, alloting small areas to subcontractors who are held re- sponsible for the proper utilization on their area. A full crew usually consists of three contractors, about 40 subcontractors, and approximately 100 laborers, most of whom are Mexicans who make their homes in Northern New Mexico. From one-third to one-fourth of the laborers are from the State of Chihuahua, Mexico. These are the most efficient and rapid tie makers, each man averaging about 25 ties per day, while the natives average only 18. A few Picuris Indians have worked at intervals but can not be depended upon for steady labor. An unskilled laborer in this locality receives $1.50 per ten-hour day, without board. The subcontractor organizes his gang, consisting of from two to five men, and pitches his tent or some simple shelter close to water which may be near his area. The matter of available water has a great bearing on the desirability of any area. It is difficult to get men to make ties in timber that is more than a mile from a spring or stream. The tie makers or, as they are commonly called, "tie hackers" use the following tools and equipment ; one 4 to 4I pound double- bitted axe and one 12 inch broad-axe to each man, and one 5 to 6 foot cross-cut saw, one steel wedge, one light sledge hammer, one 8- foot measuring pole and a bottle of kerosene (to cut the Crossties in Northern New Mexico. 41 1 pitch from the saw) to every two men. These are furnished by the tie makers themselves. Enough trees for the day's cut are notched by the men, work- ing singly, in such a manner that when they are felled any crooks the trees may contain will be perpendicular to the ground. The object of this is to face the tie so that when finished it will lie flat on the ground. Care is also taken with small trees that their greatest diameter is perpendicular to the ground. This gives the ties the widest possible face and necessitates less scoring. After the trees are notched two men fall them with a cross-cut saw. Two methods of scoring are employed. In the more prevalent method followed by the native Mexicans the chopper stands on the fallen tree and with the axe cuts into its side at an angle of about 45 degrees at intervals of about six inches. The Chihua- huans, in scoring, stand at the side of the fallen tree and split large slabs from its side until it is nearly the desired size. This method requires more skill on the part of the chopper but is more rapid and leaves no possibility of the score hacks showing after the tie has been faced. The limbs are chopped off as they are reached in scoring. In facing, the maker stands on top of the tree in all cases and with the broadaxe works the two faces to their desired size and smoothness. The "cant" or faced tree is then bucked into 8-foot lengths with the crosscut saw. The unfaced sides of the larger ties are hewn until they become rectangular, making them into squares. The bark is then peeled from the unfaced sides of the remaining smaller ties. As this requires no skill it is often done by boys or apprentices. The following prices are paid for making the ties : — Squares, $0.14 Drys, 0.12 Firsts, o.io Seconds, 0.08 The average price, including the culls for which nothing is paid, is $0.09 per tie. The contractors sublet the making at prac- tically the same prices, expecting to make their profit on the haul from the woods to the river. In timber averaging three ties per tree, two men, making 40 ties 412 Forestry Quarterly. in a ten-hour day, will spend i^ hours felling, 3^ hours limbing and scoring, 3 hours facing, i hour bucking, i^ hours peeling. At this rate the average cost of each operation is as follows : — Felling, $0.01 1 per tie Limbing and Scoring, .032 " " Facing, 027 " " Bucking, .009 " " Peeling, ,011 (( ii ii a Total, $0.09 One man making 20 ties per day of the average grades earns $1.83 per day. However, loss of time due to getting supplies and inspections and the wear and tear on tools reduces their daily wage to approximately $1.50 per day. The season in which most of the hewn ties are made is between May first and October first. While the better tie makers prefer to work during the summer, some of the less skillful prefer to work during the winter, because the frozen timber is less liable to sliver, rendering it easier for the less skillful man to make a smooth face on a crooked-grained or knotty tie. Brush Disposal. All limbs are lopped from tops which are left in the woods. Large limbs are cut up so that when piled the piles are about four feet high and eight feet across. The piles are placed from ten to fifteen feet from the nearest top, tree, reproduction or other in- flammable material, except in extreme cases which would work a hardship on the operators. Such cases are left to the discre- tion of the Forest Officer in charge of the sale. As a rule each tie maker piles his own brush for which the operators pay him $0.03 per tree, or approximately $0,011 per tie. Skidding, Hauling and Yarding. The contractors are desirous of allowing a month or two to elapse between the time the ties are made and the time they are hauled in order to take advantage of the weight lost in drying. In some cases it is possible for the haulers to drive to where the ties lie in the woods and load them directly on their wagons. Where this is impossible skidding is necessary. Skidding is usual- Crossties in Northern New Mexico. 413 ly done by a man and one horse. A chain about six feet long having three or four grabs about 18 inches apart is used. The grabs are driven into one of the faces near the end of the tie. Two to four ties are skidded at each trip. Where more ties are skidded at one time an extra chain is needed. With the use of an extra chain three ties are skidded in front and two or more trail- ers are hooked to the rear of these. The number of ties skidded in a day by one man and horse varies greatly with the distance which they are skidded and obstructions, such as underbrush, rocks, steep slopes, and arroyos. A man and horse can skid 500 ties in a ten-hour day on the mesas, which are comparatively level and free from underbrush, or where the skidding distance is short. In the canyons and on the brushy slopes of the Douglas fir type, or where the ties must be skidded 200 yards or more or where they are scattered, one man and a horse can skid but from 150 to 200 ties per day. The ties are loaded on wagons which have been lengthened enough to permit two tiers of ties to be piled end to end. An average load for a team of the small native horses is about 25 ties. Ordinarily each man requires about one-half hour to load the ties and bind them on the wagon with a chain. The average haul from the areas at present allotted the con- tractors to the yards at the river is about two miles, all of which is down grade over comparatively good roads. For this haul they receive $0.09 per tie for all classes. Subcontracts are let at different prices, varying according to the distance the ties must be hauled and the accessibility of the areas. The haulers receive from S0.05 for the shorter hauls to $0.10 for the longer and more difficult ones, with an average of about $0,065 P^^" tie. The haul- ers are required to construct all but the main trunk roads, many of which are county roads. The number of trips a man and team can make in one day varies from two on the longer hauls, or where skidding is difficult, to four trips on the shorter hauls or where skidding is easy or unnecessary. One man and team can skid and haul an average of 75 ties per day. At this rate he earns about $4.86 per day actual time, but considerable time is lost due to breakdowns and inclement weather which considerably re- duces the haulers' average wage. About fifteen minutes are required for the hauler to unload and pile his load in the yard. In piling, two ties are laid on the 414 Forestry Quarterly. ground about five feet apart. About eight ties are placed across these forming the first tier. Other tiers are then laid upon these, the ties of each tier being at right angles to those of the tier below. The piles contain about fifty ties each and are placed two feet apart. The piles are placed as close to the edge of the water as possible, and not more than five piles back from the river, to prevent carrying the ties considerable distances when they are put in the river in the spring. Each contractor furnishes or rents his own yard. One con- tractor yarding about 50,000 ties this year paid $50.00 yard rent, or $0,001 per tie. However, as the majority qif ithis year's ties are yarded on rich agricultural land which is under irrigation, this is believed to be slightly above the average an- nual cost of yarding. Sawn Ties — Woods to River. Sawn ties, at present, are being made only from Western Yellow pine and Douglas fir. The entire operation from the felling of the timber to the delivering of the tie at the river is covered by contract with one contractor, who in turn lets sub- contracts for the cutting and hauling of the saw-logs to the mill and the hauling of the ties from the mill to the river. Logging. The logging does not differ from that of any other small operation in Northern New Mexico. Felling, Limbing, and Bucking. These operations are usually covered by a single contract. Only 1 6- foot logs are cut for which the choppers receive $0.75 per M. feet, Doyle scale. Skidding and Hauling. Skidding and hauling are included in one contract. On some of the steep slopes it is necessary to skid as much as an eighth of a mile. The length of haul varies from one-fourth of a mile to three miles. The average haul is about one and one- half miles, for which $3.00 is the average price paid. Milling Equipment. The contractor uses a portable mill having a daily capacity of about 10 M. feet B. M, The mill is composed of one 45-horse- Crossties in Northern New Mexico. 415 power boiler, one 35-horsepower engine (which runs the cir- cular saw, feed and edger), one 6-horse power engine (which runs the cut-off saw), friction feed with cable, edger, and cut- off saw. The cost of this mill is approximately as follows: Boiler and 2 engines, second hand, $650.00 Mandrel, husk, feed works, carriage and track, new, 300 . 00 Two 60-inch circular saws, new at $100 each, 200.00 One edger, new, 250 . 00 One 30 inch cut-off saw, with attachments, . 35- 00 Freight and hauling, 100.00 Total, $1,535.00 The mill has been used in this condition for five years, and, with considerable repairing, can probably be used for about five years longer. Moving Mill. The mill was moved a distance of six miles and set up in the winter on a trestle work about eight feet above the ground. The rollway is also on trestle work, and because of the small space available for the mill site, contains an angle of nearly 45 degrees. When the ground thawed in the spring the foundation settled, making re-inforcement of the foundation and realignment of the machinery necessary. The water supply failed with the approach of the dry season. In addition to a delay of about a month this necessitated an additional expenditure of about $100.00 for water development. The angle in the rollway requires the services of an extra man for turning logs, and even then often causes delays. The banking ground for logs' is inadequate and it has been necessary to stop logging at times because of the lack of space. The edger is on the opposite side of the carriage track from the saw. The logs used in the trestle work and rollway contain about 20 M. feet, B. M. The trestle work rendered flooring of the mill neces- sary, and this required 2 M. feet of lumber which would not otherwise have been needed. About 3.5 M. feet B. M. were used in roofing. The cost of moving and setting up the mill under considera- tion is estimated at about $600.00, but for the reasons given 4l6 Forestry Quarterly. above, this cost is considered excessive. Another mill of about the same capacity was moved the same distance and set up in this locality for less than $200.00. The contractor expects to be able to cut 4,000 M feet B. M. at this set. This gives a cost of $0.15 per M. feet. SaTmng. The mill, when running at full capacity employs, in addition to the contractor who is foreman and filer, the following crew: I Sawyer, $4. 50 per day I Fireman, 2 . 50 per day I Man tailing down i • 75 per day I Log turner, i . 75 per day I Ratchet setter, 2.25 per day I Off-bearer, i . 50 per day I Edgeman, 2.00 per day I Cut-off man 2.00 per day I Roller man i • 50 per day I Lumber piler i • 50 per day I Man wheeling sawdust i . 50 per day Total daily wage, $22.75 Allowing contractor's wages, 4- 50 Total pay roll, $27.25 per day With an average cut of 10 M. feet per day, the average cost of sawing is $2.72 per M. feet. Depreciation of Plant. As it is estimated that the mill will have no wrecking value at the end of five years, it is now worth about one-half of its original cost, or $767.50. An annual cut of 2,000 M. feet would, require $153.50 to be charged off annually, or $0,077 P^^ ^^^ feet. Interest on Investmetit. The present value of the mill and the value of tools', belting and equipment aggregates $1,000.00. With an annual cut as Crossties in Northern New Mexico. 417 above, the interest at 6% would be $6o.(X), or $0.03 per M. feet. Taxes, Repairs and Maintenance. The mill was assessed at $400 or approximately one-third of its valuation by the County Assessor. The taxes at $0.04 per dollar amounted to $16.00 for the year 1912. The outlay for taxes, repairs, files and oil aggregate about $250.00 per year, or $0.13 per M. feet. Grades and Prices. At the present time the mill-run averages about 60% ties and 40% side lumber. Side lumber is produced incidental to the squaring of a tie cant and the sawing of ties from the heart- wood. The percentage of ties is low, due to the fact that the company does not accept sawn ties showing any defect or wane. The lumber is graded in but two arbitrary grades which run 85% No. I and 15% shipping culls. The contractor receives $7.50 per M. feet for both grades of sawed lumber piled at the mill. The company is able to dispose of a limited amount of lumber for local consumption at $15.00 per M. feet, B. M., for No. I and $8.00 per M. feet for the shipping culls. The re- mainder will have to be hauled 30 miles over rough roads to the railroad at a cost of $6.50 per M. No further consideration will be made of the side lumber since no data is available as to amount that will be disposed of locally and the amount to be hauled to the railroad, but it is thought that the company makes very little profit on the side lumber. About 65% of the ties are cut 7 inches by 9 inches, 8 feet long; 25% 7 inches by 8 inches, 8 feet long; 10% 6 inches by 8 inches, 8 feet long. With the above percentages and allowing 24 7x9*3, 2y yxS's and 32 6x8's per M. feet, B. M., the average is 25 ties per M. feet. The contractor receives $6.00 per M. feet, B. M. for the ties at the mill, or 24 cents per tie. The average price received by the contractor for the mill run is : Side lumber at $7.50 per M. ft, B. M., 40%, $3.00 Ties at $6.00 per M. feet, B.

The contractor is relieved of the side lumber at the mill, but is required to deliver the ties in the yard at the river. For this he receives $0.05 per tie. He sublets the contract to two men at $0.04, making a profit of $0.01 per tie or $0.25 per M. feet, B. M. The haul is all down hill a distance of two miles. The haulers average about three trips per day and haul about 30 ties at each trip. At this rate their wages average $3.60 per day. The men hauling sawn ties earn smaller wages than those hauling hewn ties, but have steady employment. Hewn ami Sawn Ties — Yards to Cars. Placing in River. The ties are placed in the river when the spring freshet is at its height. About 200 men were employed for common labor Crossties in Northern New Mexico. 419 at $1.50 per day without board, while 30 Mexican patrons re- ceived from $1.75 to $2.50 per day without board, and 10 Ameri- cans received from $2.50 to $3.00 per day with board. The head foreman received $4.50 per day with board. Forty men with a payroll of $70.00 placed 22,000 ties in the river in one day. This gives an average of $0,003 P^^ tie. How- ever, when all things are considered, such as isolated yards, dis- tance of piles from river, depth of water, and current at point where thrown in, it is believed that on the average this cost will be approximately $0,005 P^^ tie. Driznng. About $4,000.00 is spent annually in clearing out the rivers in preparation for the season's drive. Some piles were so placed that the spring freshet carried them away before the drive started. Many of these ties became water-logged and interfered with the driving, causing trouble enough to more than offset what the cost of placing them in the river would have been. The drive proper is quite similar to a log drive in the northeast. On the smaller streams the camp or wongan is moved every few days with a wagon, but on the larger river it follows the men in boats. A few men were put on the drive as soon as the ties were started. The drive proper started with about 150 men and ended with about 15 men, with an average of approximately 65 men. most of whom received their board. About 80 days were re- quired, from the time the ties were first placed in the river until the rear of the drive reached the boom, covered a distance of about 90 miles. This time was required to break jams, keep the ties moving, place stranded ties in the stream, take out dead heads and remove boulders loosened by the ties. About 6,000 ties became stranded and water-logged but will be picked up next year. A like number of last year's ties were picked up in their place. The following data is based on a drive of 300,000 ties, as the company considers this an average economical drive. Approximately 3,000 ties were broken in the jams and by dynamiting. It is believed that these ties cost the company $0.28 each at the time they were broken, making a total cost of about $840.00. During the drive damages caused to ditches and land adjacent to the rivers, for which the com- pany is held responsible, amount to about $600.00. 420 I'oresiry Quarterly. The cost of driving may be summarized as follows: Clearing river, $4,000 . 00 10 Americans at $3.00 per day, 80 days, .... 2,400.00 65 Mexicans at $1.75 per day, 80 days, .... 7,700.00 Board, 50 men at $0.50 per day, 80 days, 2,000.00 3,000 broken ties at $0.28, 840.00 Damages, 600.00 Dynamite and pike poles, 100. 00 Camp equipment, 250 . 00 Total, $17,890.00 This makes the average cost of driving $0.06 per tie. Booming. The boom is about 800 feet long and is composed of 92 thirty-foot yellow pine logs from 18 to 30 inches in diameter, with an average diameter of about 22 inches. In the case of small logs they are often placed two deep. Two logs are fastened side by side with pieces of cull ties. Often cull ties are spiked on top of the logs. The pairs of logs are fastened together, end to end about 18 inches apart with large chains passed through the ends of the logs. The logs were hauled by wagon a distance of 10 to 15 miles at a cost of $2.00 per log. The boom is taken out of the river every sum- mer at the close of the loading operations. With such care the boom is replaced about every six years. Sixteen square cribs hold the boom in place diagonally across the river. Each crib is constructed of about 6 tiers of 16-foot logs about 6 inches in diameter. These are filled with rocks. The construction of each crib required the services of 6 men for about 4 days. The improvements to be charged off in six years are as fol- lows : Boom — 60 M. feet logs at $1.00 per M, $60.00 Hauling at $2.00 per log, 185.00 Boom chains, 100 at $1.50, 150.00 Cribs Logs and hauling, 100 . 00 Building 16 cribs, 6 men 4 days at $1.75 . . • 672.00 Total, $1,167.00 Crossties in Northern New Mexico. 421 This makes a charge of about $0,001 per tie on the 1,800,000 ties exploited in the six years. A canal was dug to a pond about a quarter of a mile below the boom. This provided for the storage of the ties until they could be loaded. The digging of this canal required the work of 20 men for about 25 days, for which they received an average of $1.75 per day, which totaled, $875 . 00 A levee was built along the canal and around the pond to keep the ties from escaping in case of an overflow, at a cost of $3,500.00 The construction of an office, bunk house, sheds and other outbuildings aggre- gated $3,000.00 Total improvements to be charged off during life of operation, 20 years, $7,375.00 On 6,000,000 ties to be exploited in the 20 years, this gives a per tie cost of about $0,001. The annual recurring booming charges are as follows: The services of 10 men and teams for 10 days are required to put the boom into the river at $3.00 per day for team and driver this cost is, $300.00 The cost of pulling the boom out each year with teams aggregates, $400.00 A care-taker is kept at the boom camp the entire year, whose salary is about .... $480.00 An average of 5,000 ties pass the boom each year and must be picked up along the river below the boom and hauled to the railroad at a cost of $0.10 per tie, ag- gregating, $500.00 Total, $1,680.00 This, together with the improvement charges, aggregates $0,008 per tie. 422 forestry Quarterly. Loading on Cars. The loading is done with the aid of three endless chain con- veyors. A six or seven horsepower gas engine furnishes the power for one, while the other two are run by a 15-horsepower upright boiler and engine. Each conveyor is composed of two endless chains about 50 feet long fastened together 3 feet apart with pieces of 4-inch strap iron. The following crew, not including men along the canal and on the pond, is used for each conveyor: Four men in car, one engineer or leverman, 1-2 tie inspectors, four men in water at foot of conveyor. In a lo-hour day 150 men can load 40 cars. As gondolas are used they hold about 300 firsts or, as they are more com- monly loaded, 425 firsts and seconds. Each car contains an average of 190 firsts and 235 seconds. About thirty days are required to load the ties working continually, but a longer time is required as the ties arrive at the boom irregularly. About 7 tons of coal and 200 gallons of fuel oil are reported to run the engines. The value of the loading equipment is so small that the charge per tie is almost negligible. The loading charges may be summarized as follows: Labor Per Tie. 150 men at $2.00, loading 17,000 ties $0,018 Fuel and Oil 7 tons coal at $6.00, $42 . 00 200 gals, fuel oil at $0.15,. . 30.00 $72 . 00 Oil, 10 gals, at $0.40, 4.00 Total, $76.00 o.ooi Total Loading Charges $0,019 It is believed that loss of time and shortage of cars increase this cost to $0.02 per tie. Supervision. The woods administrative force consists' of one superintendent, one bookkeeper, and one tie inspector, whose salaries aggre- Crossties in Northern Nezv Mexico. 423 gate about $5,000.00. Since a part of their duties is to ad- minister the grazing of 1,200 cattle and horses and 4,000 sheep and goats on the company's holdings, as well as to supervise the commissaries operated by the company, all of this sum should not be charged against the company's tie operations. A small ranch is also operated on which a portion of their forage and provisions is' grown. For the above reasons it is believed that of the $5,000.00 but $4,000.00 should be directly chargeable to the tie operations. The expenses of the main office, such as salaries of book- keeper and stenographer's, stationery and supplies, and office rent amount to $9,000.00. The total annual charges against supervision aggregate $13,000.00, or $0,043 P^i" tie. Interest on Capital Involved. The entire 300,000 ties' have, at this point, cost the company about $0.33 per average tie. The cost of the annual output is in- vested for at least six months. The interest on $99,000.00 at 6% for six months is $2,970 or approximately $0.01 per tie. Stumpage. The timber from which the hewn ties are made is valued at $2.50 per M. feet B. M. The original agreement between the (J. S. Forest Service and the company under which the timber is being cut contained the following clause : "Hewn railroad ties without disqualifying defects whose widest diameter inside the bark at the small end exceeds 12 inches will be scaled." In actual practice it was found that this would not work out satisfactorily to all parties concerned. In the first place it was impossible for the Forest Officer to be on the ground when all ties over 11 inches by 8 inches were squared to these dimensions. The Forest Officer had no way of knowing from what sized log the tie was made. Secondly, such a clause worked a hardship on the company by causing them to pay for material which they could not use. It was more satisfactory to count all ties in number equivalent to 1,000 feet board measure ac- cording to size. The squares and faced ties whose largest 424 Forestry Quarterly. diameter at the small end was more than 12 inches were counted at 28 per M feet, B. M., while the other faced ties were counted at 32 per M. feet B. M. 3.5 per cent of the faced ties were over 12 inches, and were counted by the Forest Officer at 28 per M. This amount is too small to have any appreciable effect on the ^tumpage value per tie. At 28 per M. feet B. M., each tie is worth $0,089, while those counted at 32 per M. are valued at $0,078 per tie. SUMMARY Cost per Tie F. O. B.

FOREST TYPE: A DEFENSE OF LOOSE USAGE. By E. H. Frothingham. Almost from the beginning of forestry in America the ex- pression "forest type" has been used by writers in this field, each using it in his own way, and apparently to his own and his readers' perfect satisfaction. This happy state of affairs was not of long life. Questions as to the precise meaning of the term were raised by cautious critics, and strenuous attempts were made to fix a standard definition for "forest type." In consequence, those who have been addicted to the lavish use of the word can hardly avoid a feeling of uncertainty, as of con- fidence misplaced. In the "Symposium"* recently conducted by the Society of American Foresters the attempt was apparently made to clear up the existing confusion as to the meaning of "forest type," and to arrive at some standard definition or definitions. What- ever its object, the "Symposium" has- not clarified the situation; it might, indeed, be said to have left "confusion worse con- founded." When ideas clash, words are often to blame. It is possible, then, that a glance at the word "type" in its ordinary usage will reveal the source of the trouble. Before proceeding, however, it would be well to review the qualifications that a word must have for technical use. In his comments on "Terms Used in Forestry and Logging,"* Dr. Fernow has proposed a number of standards by which to test the situation of technical terms. All of these apply to the case in hand; but one in particular is of interest here: b. Words' which are current with well established meanings should not be employed as terms in another sense, especially where it is likely that ambiguity would be introduced by the simultaneous use of the ordinary sense and the term meaning. Are we not committing this very error when we borrow the word "type" from recognized usage and impress it for service, ♦Proceedings, Society of American Forresters, Vol. VIII, No. i, pp. 61-104. ♦Forestry Quarterly, Vol. 3, No. 3, pp. 255-268. 426 Forestry Quarterly. not in one, but in several different new senses, thus inevitably in- troducing the ambiguity referred to? The New Standard Dictionary publishes 13 distinct definitions of "type," of which the following have a direct or remote bear- ing upon the various uses in forestry which have been pro- posed for the word : Type, n. — 3. One of a class or group of objects that embodies the characteristics of the group or class; an example, model, representative, or pattern, as of an age, a school, or a stage of civilization; also a character- istic style or kind ; as the blond "type" of beauty. 4. Biol, (i) Plan of structure; a fundamental structure common to a number of individuals; as, the vertebrate type. (2) The ideal representation combining essential characteristics, as of a species, genus, or family ; an organism exhibiting the essential characteristics of its group 8. A plan to which proposed work or action should conform; guiding style; specif., in the fine arts, an original ob- ject or conception as the subject of copy. The first of these definitions is one which a person unfamiliar with forest terms would be apt to understand by "forest type," since it is in the sense of "a characteristic style or kind" that the word is most commonly heard in general usage. But the authors of the "Symposium" have used the word in all three of these senses : ( i ) in the sense of "a characteristic style or kind," to denote a "kind of forest," designated either by the principal species which compose it or by the character of the land it oc- cupies; (2) in the biological sense of "the ideal representation combining essential characteristics," referring not to the essential characteristics of individual trees as "types" of species or genera, but, strangely, to those of the soil and climate; and (3) in the sense of a "plan to which proposed work or action should con- form," to designate a kind of forest which it is believed desirable to produce. There are here three distinct meanings of the expression "for- est type" — and there are possibly others. To assume that a single technical term can be applied satisfactorily to ideas so Forest Type: A Defense of Loose Usage. 427 distinct and at the same time so closely associated within the bounds of a single science is, of course, absurd. Furthermore, its specific application to anyone of them invalidates it for either of the others; but all of the ideas must find expression, and all involve, in one sense or another, the notion of "type." The solution seems, therefore, to lie in the substitution for the word "forest" of some more specific term, designating the category to which the type belongs. This has already been done. The three terms cover type, phys-ieal type, and management type have recently been pro- posed, to denote what are in effect the three ideas above men- tioned. Of course, however, only one — cover type — actually re- fers to the existing forest itself. The others relate to (i) locality, and not existing forest; (2) future forest, and not existing forest. It seems clear, therefore, that the expression "forest type" has one and only one logical application, and that in the sense of a "characteristic style or kind" of existing forest. The basis on which the distinction between forest types should rest can not be constant any more than if the words "style" or "kind" were substituted for "type." The term is extremely elastic. It varies with the purpose of the author, but in spite of this, it can not mislead, since we expect nothing more from the word "type" than is specifically provided by the author's definition. A "hardwood type" may be, by this definition, noth- ing more than a kind of forest consisting of hardwoods, but it may also, of course, represent a definite relation of forest and environmental factors if the author makes clear that he is giving it this meaning ; similarly, a birch-beech-maple type may be merely a kind of forest consisting of birch, beech and maple, or it may be a climax forest for definite physical conditions. Ex- cept for the different degrees of intensity which individual authors may, by definition, give the term, the meaning of "forest type," as of "kind" or "sort" can not be limited without a sacrifice of con- sistency and precision. In papers dealing with forestry from the ecological standpoint, it would often be better, therefore, to employ the terms used in ecology. Among ecologists, a forest considered with relation to its total environmental factors would be called a "formation," and as this term is without an equivalent in American forestry there 428 Forestry Quarterly. is no reason why it should not be adopted. For use in a general scheme of forest classification it would be most serviceable. Used to designate "locality" the term "forest type" is totally inconsistent, as has been shown by Barrington Moore.* Mr. Moore's point is that "physical factors are the cause of forest types; hence can not be forest types' in themselves." The "aggregate of physical factors" is often implied in the words "locality" or "site." Like "type," "locality" and "site" should be used in harmony with their common usage, and their intelligibility should not be endangered by special technical mean- ings. To classify aggregates of physical factors, it would, of course, be perfectly proper to use either "locality" or "site" in connection with "type," just as "forest" is used with "type" to designate kinds of forest. "Habitat" differs from these in that it denotes all environmental factors, both physical and physiologi- cal. Compounded either as "habitat type" or "locality type," there would be no danger of confusion with "forest type," and the terms would be self-explanatory. The above discussion has attempted to show that the term "forest type" is exceedingly useful in silviculture and forest description, so long as it is allowed perfect freedom; that it is elastic and adaptable to modification by different writers to serve any specific purpose, provided this is done in the sense of "kind" or "style" of forest and not otherwise; but that as a general expression in forest terminology any attempt to limit its meaning to a restricted technical sense can result only in ambiguity and destroy to that degree its usefulness. It may be said in dispute of these points that they amount to a distinction without a difference. If the author may define "type" to suit himself, why may not the profession at large agree on a rigid definition? The answer to this, like the ancient re- ceipt for rabbit stew, is "first catch your agreement." If perfect agreement can be secured, the demands of intelligibility will, of course, be satisfied. Until this is accomplished, however, the word "type," in true proletarian fashion, will refuse to work at the expense of liberty. ^Proceedings, Soc. of Amer. Foresters, Vol. VIII, No. i, pp. 73-75- THE SCOPE OF DENDROLOGY— SOME CORREC- TIONS. By H. de Forest. A careful consideration of my paper on "The Scope of Den- drology in Forest Botany" appearing in the June number of the Quarterly will not support the conclusion of Dr. Howe that I hold the subject of silvics to be a study of associations of trees alone. The paper states definitely that I consider silvics to cover all ecological investigations' of forests, that such investiga- tion is pursued by means of plant-geography and plant-ecology, one part of the latter dealing with the ecological significance of the morphological and physiological characteristics of the plants of a locality, (the part Dr. Howe says I exclude from silvics), and the other part dealing with the local minutiae of vegetation. Dendrology, I believe, deals with facts concerning the indi- vidual tree species that go to make up the forest. Dr. Howe in his appended comment says that this ''would include the study of the biological relationships of single trees." It is undoubtedly and obviously true that the facts mentioned are deduced from the study of the biologic relationships of trees. It is not, how- ever, necessarily true that dendrology itself should include this study. In systematic dendrology, for example, students learn certain facts, certain "ear marks" of tree species Dr. Howe calls them, in order to be able to identify species, but they do not in that subject go into the problems of how and why these "ear marks" occur. The latter is recognized as belonging to another part of botany. The case between dendrology and silvics is somewhat similar. Dendrology has arisen in response to needs. The need so far as biologic dendrology is concerned may be stated as the necessity in educating foresters for giving to them early in their course of training a systematized collection of facts concerning the chief biologic characteristics of important species. It is especially needful in forestry education to learn what may be termed metaphorically the numbers and numeration of the subject 430 Forestry Quarterly. before engaging in its mathematical processes. Silvics embraces, so to speak, the problems and runs into the higher miathematics. I must protest against the statement that I have said forest- ecology stops the moment practical considerations enter and silvics begins only when practical considerations are in hand. I stated that "the point of view of silvics is different (from that of forest- ecolog}') because of its different object. The forest-ecology of the botanists is concerned with adding to the sum total of botan- ical knowledge. Silvics of the foresters, on the other hand, is concerned with ... all forest investigations . . . that bear in any way upon the practical questions of forest production." The well known fact that botanical research has the high purpose of adding to the sum total of botanical knowledge while forestry re- search has the high purpose of furthering the interests of forest production as their main objects is obviously not exclusive of practical activity on the part of botanists, nor entirely, I hope, of activity purely for the sake of knowledge on the part of for- esters. A botanist does, of course, distinguish herbaceous plants in the field by certain "ear marks." In other words he uses a method somewhat similar to that used by foresters with trees and shrubs. Botanists, however, have not as yet developed their "ear marks" for herbs into the definite form that foresters have developed theirs for trees and shrubs. It is a noteworthy fact that leading taxonomists among botanists protest frequently to-day against the unnecessarily difficult taxonomic schemes given in many manuals schemes derived mainly from herbarium specimens rather than fresh material, and often involving characters that appear in na- ture only several months apart. The "complete taxonomic scheme" of botany mentioned in my paper involves, it is well known, the recognition of the different orders found along the three main lines of advancement from primitive to highly specialized characters, with the various families belonging to each, the connecting thread to-day being genetic relationship. Further, the characters there considered are largely floral. As much of this as the prospective forestry student needs belongs, I think, to his botanical study proper. Systematic dendrology, as my paper states, does not deal with most of this material but only with such characteristics as are of service in field identifi- Jlie Scope of Dendrology. 431 cation. I fail to see why the recognition of the difference be- tween this important work of botanical taxonomy and the work of systematic dendrology, serving two different purposes, con- stitutes a hair-splitting between the "scientific" and the "prac- tical." The expression "sister sciences of plant-geography and plant- ecology," used in my paper was employed in the sense common throughout English literature as a metaphorical equivalent for "closely related." It indicates no exact family relationship. I do not believe Dr. Howe's remarks on plant-geography and plant-ecology are abreast with the best later developments of these subjects. As certain botanical journals have expressed an intention to review this aspect of the paper discussion here is unnecessary. Since its publication the paper has been read at my request by several American botanists who tell me, without exception that they not only find it clear but also do not get from it any such impression as Dr. Howe appears to have been given. [The Editor has reluctantly given additional space to this academic discussion in order to satisfy the author's sense of injury by Dr. Howe's criticism. He must, however, protest that there is still perversion in the definitions of the author, if the originators of terms have any right to give them their meaning. The combination "biological dendrology" was for the first time used by the Editor (so far as he knows) in making out a curricu- lum for the forestry courses at Cornell University, and he knew perfectly well what he meant, namely, not "the chief biologic char- acteristics of important species" as the author proposes to define, but a statement of the general biological laws to which trees of any species are submitted in their development. On the other hand, it was Dr. Gifford as Assistant Professor at Cornell, who invented the term silvics, really as a mere shortening of the phrase "silvi- cultural characteristics (i. e. part of the biology) of important species," — precisely what the author proposes to make the defini- tion of the broader subject of biological dendrology. As this definition suggests, silvics has, indeed, a practical object — silviculture — in view. It does not, however, deal with problems but with facts or observations. The problems begin only when silviculture is to be practised, namely, how to apply these observa- tions or facts. This much was needful to add in view of the committee work on terminology by the Society of American Foresters.] COST OF GROWING TIMBER ON THE PACIFIC COAST. By H. R. McMillan. Professor Kirkland of the University of Washington Forest School addressed the British Columbia Forest Club on the cost of growing timber in the Pacific North West. The discussion was based on the crop which can be produced on second quality soil, valued at not more than $5.00 per acre. It is estimated that there are 10,000,000 to 15,000,000 acres at least of this soil type in the Vancouver and Vancouver Island Forest Districts. The yield according to Munger's yield tables is estimated to be 100,000 feet per acre in 100 years on Site i ; 65,000 feet per acre in one hundred years on Site 2; 35,000 feet per acre in one hundred years on Site 3. The costs which will enter into the production of timber are : — 1. The interest on the cost of land — This cost would not be felt directly by the Government of the Province or State, but would bear heavily on the private owner who has purchased land. 2. Cost of reforestation — This will vary from zero ( ?) to $12.00 per acre. The average for the regions discussed was con- sidered to be $5.00. 3. Interest compounded on cost of reforestation, 4. Cost of administration at 20 cents per acre per year. This cost appears high, the United States Forest Service is calculated as spending 2 cents per acre per year. But it must be remem- bered that in this calculation barren areas are eliminated. The cost of administration on the National Forests' now is about 10 cents per acre for the forest areas actually effected by administra- tion, 5. Compound interest on the cost of administration. 6. Taxes. 7. Interest compounded on taxes. On this type of soil at the end of sixty years it is estimated that the yield in Douglas Fir will be 52 M feet per acre. The cost per M feet of growing it under a sixty year rota- tion is : — Cost of Growing Timber on Pacific Coast. 433 I. At 3%, the Federal Government Interest rate $3-54 16 42 27 2.

" 6%, the interest rate paid by the moderate sized corporation 15 6. " 7%, the interest rate paid by small corporation or in- dividual 25 21 77 The deduction to be made from this table is that the growing of timber is a function to be performed by Federal, Provincial or State Governments and Municipalities. The policy of Cana- dian Governments in reserving timber lands is thus economically sound. The interest rates quoted are interest rates ruling in the North- western States. There is not in Canada the same difference in interest rates paid by Dominion and Provincial Governments as exists between rates paid by the Federal and State Govern- ments in the States. The Province will not be at such a disad- vantage in growing timber as appears in the comparison quoted. The large owner is not entirely out of court. Stumpage value of White pine is now over $16.00 per M in Eastern Canada. It is reasonable to expect that stumpage in the West will eventually reach this point. The large owner who can borrow money at 5% will then be able to grow timber at a profit. Another interesting deduction is the effect of taxation on forestry by private owners. Professor Kirkland pointed out that the taxation rate is now claimed to be the chief obstacle to the growing of timber by private owners. He disagreed with this objection, holding that the interest rate paid by private owners was an even greater obstacle. Where the rate of interest is 5%, and taxes the present average in the Pacific Northwest, i-| cents per thousand feet annually, the tax, with interest on taxes, is only 15 per cent of the cost of growing timber on a rotation of sixty years, while other interest charges are 75 per cent of the total cost. Where the interest rate is 6 per cent the proportions become 11 per cent and 81 per cent respectively, and where the interest rate is 7 per cent the propor- tions are 9 per cent and 86 per cent. Clearly the rate of interest 434 Forestry Quarterly. is a much more important factor than is taxation in determining whether the Government or the individual will grow the forests. The argument outlined above does not apply to the woodlot owner as it does to the private owner of large tracts of timber land. The woodlot owner is freed from considering many costs which vitally afifect large owners, labor, interest in the land cost, cost of restocking, and frequently taxes.

The Trent Watershed Survey. By C. D. Howe and J. H. White, with introductory discussion by B. E. Fernow. Commission of Conservation. Ottawa 191 3. P. 156. This report issued by the Canadian Commission on Conserva- tion after a careful field study of a mismanaged forest area in Ontario is quite the most valuable publication on forestry which has yet appeared in Canada. It throws the spotlight on the results inevitably following the mismanagement of forests in Eastern Canada. The area described is typical of the greatest forest region of Canada, the Archaean formation characteristic of the permanent timberlands throughout Canada east of Lake Winnipeg, and even west of Lake Winnipeg, north of the prairies. What is true of the 2100 square miles of the Trent valley in Old Ontario is true of hundreds of thousands of square miles in New Ontario, Que- bec. New Brunswick and Nova Scotia where the forest, the only possible crop, has been left to manage itself. The Trent Valley was originally heavily forested, two-thirds pine, chiefly. white, and one-third hardwoods, beech and maple. Lumbering under the licence system began in 1840, reached the maximum cut of 160 million feet per year in 1872 and dwindled to 18,000,000 feet pine, 24,000,000 feet hardwoods in 191 1. The pine will be cut out in five years. The forest was milked. The total cut of timber and total revenue received is not shown ; whatever the revenue may have been none of it was used to perpetuate the forest. No expendi- ture was made, no care was taken to protect logged over lands from fire or to encourage another crop of timber, even though the Government was informed that the land was non-agricultural. The results of this policy as already apparent, are shown in the report, both generally for the region and in detail for each town- ship. A similar policy of destructive lumbering and neglect of logged over lands' by governments is still in force in many ex- 436 Forestry Quarterly. tensive regions in Canada; therefore the conditions disclosed by this survey merit special study. The whole pinery has been burned over once and in many places several times. Where originally one million acres of pine stood there are now 560,000 acres of poplar and birch, 300,000 acres of cordwood and 90,000 acres of moderately culled timber. There has not been, and is not now any fire protection except in the few square miles of remaining licenses and there is no attempt to encourage and protect the natural reproduction of the extremely valuable White pine. On the average 14,000 acres are burned over annually. Fires in 1913, since the com- pletion of the survey covered 175,000 acres and did damage es- timated at $300,000. When it escapes fire White pine reproduces readily and vigorously except in repeatedly burned areas. In this district $12,000,000 worth of White pine reproduction has been destroyed by fire. The destruction goes on at the rate of $250,000 per year and not one attempt is made to prevent it. A most important feature of this report, especially for On- tario, is the clear manner in which the value of White pine repro- duction is shown. Another serious loss to the Province has been the expensive agricultural experiment carried on, an expense which can be measured only in human blood and tears. The logged over lands though known to be non-agricultural were opened to settlement fifty years ago, and settled by the same hardy timber following folk who settled the most of Eastern Canada. The report deals exhaustively with subsequent conditions. The thin soil scattered amongst boulders and rock ridges has refused to raise any crop but timber. In half a century ten per cent of the area has been cleared and the population of 2100 square miles has risen to 15,000 people. Only about two per cent of the whole area is cul- tivated. The settlers now in the country realize that the land was never meant for agriculture. The population has declined fifteen per cent in ten years; in 1912, 194 farms were to be sold for taxes averaging i8c per acre. Social conditions are unsatis- factory. Recommendations for the future management of the territory are included in the report. The district though now unproduc- tive because of lack of fire protection, is estimated to be capable Current Literature. 437 of producing 100 million feet of timber and pulpwood annually, equal to an annual business of $5,000,000 to $6,000,000, With this timber yield will come new industries and the area now in waste, may be made to produce by fire protection alone $2.00 per acre per year in perpetuity. There is now sufficient merchant- able timber on the ground to meet the cost of administration. This report reduces to definite terms the condition which is known by foresters to be true now, or becoming true, throughout extensive forest regions in Canada. It could not be more clearly shown that the failure of the Canadian people to protect forest lands from fire, to restrict agricultural settlements to agricul- tural lands, is leading in a large degree to the destruction of our forest resource and the reduction of our agricultural resource. The chief cause of delay in organizing fully equipped forest services in Eastern Canada may be the fear that such services will cost money which is needed for other apparently more pres- sing government expenditures. This study shows how a great forest reserve will quickly pay for itself by the protection of valuable young stands from fire, by the encouragement of new industries in now barren districts, by the protection of the public timber from trespass and the collection of the full public revenue. H. R. McM. Woodlot Forestry. By R. Rosenbluth. Conservation Commis- sion. State of New York, 1913. 104 pp. The literature devoted to the woodlot laid down in the great mass of articles, bulletins and other published material has been exceptionally meager in application up to the present date. The latest available statistics show that out of a total forest area of 545 million acres in this country at least 202 million are included in woodlots or in remaining portions of the original vir- gin forest which in character of ownership, products, etc. may be classed as such. Surely this is going to play an important part in the production of our future wood supplies, and therefore the proper care, maintenance and utilization of our woodlot areas are of great economic interest. It is therefore with pleasure that we welcome this latest contribution to the professional literature of the forestry profession. Many of our states have added valuable 438 Forestry Quarterly. contributions to the only too limited knowledge of certain tech- nical as well as general phases of forest distribution, growth, forest utilization and protection. Mr. Rosenbluth's bulletin entitled woodlot forestry, admirably fills the need for a complete up-to-date manual as well as treatise for woodlot owners not only in New York State but in a good portion of the northeastern section of the country. It also serves as an excellent model for investigations of similar nature in the woodlot regions. Much of the subject is generally known and understood by foresters, it is intended presumably for the use of owners of woodlots, estates, and small timber tracts and is ex- pressed in simple, direct and readily understood phraseology. And in this very particular lies the great strength, value and use- fulness of the publication. Naturally very little claim may be laid to originality and investigative research. As stated in the acknowledgments much of the material has been suggested and contributed by others. However, Mr. Rosenbluth's extensive ex- perience over the State of New York in various associated lines of work have been of great assistance to him in collecting and collaborating the material embodied in it. On page 7 it is stated that there are over 4,436,000 acres in woodlots in the state and 2,750,000 acres of unimproved land. This latter, presumably may be classed as abandoned pastures, waste land, etc. and therefore belonging in the same class as the woodlot for general forestry purposes. It is unfortunate that the planting up of waste lands has not received more attention in the bulletin, in as much as according to these figures one-third of the farm areas are not used for purely agricultural purposes. On the whole too much space is devoted to elaborating the principles involved in woodlot management and too little to the actual application of these principles. It is a well accepted fact that woodlot owners do not often get the full market value of their forest products and the bulletin would be of much greater usefulness had there been more discussion of the practicability and methods of utilizing the products of the woodlot both to assist in perpetuating the timber supply and to benefit the wood- lot owners. The space given to utilization is excellent, however, as far as it goes inasmuch as it gives at least approximate prices Current Literature. 439 paid for the principal woodlot products and shows how they can be marketed to advantage. The illustrations and drawings are unusually well selected and convey at once to the layman reader their illustrative purpose. Altogether it is a most commendable contribution to our litera- ture and it has shown the results of painstaking effort on the part of one who has familiarized himself on the subject. N. C. B. Silvical Characteristics of Canadian Trees. Compiled by For- esters' Club, University of Toronto. 19 14. P. 63. The members of the classes of 1913 and 1914, Faculty of Forestry, University of Toronto, Canada, have recently put out a publication entitled, "Silvical Characteristics of Canadian Trees." Fifty-six species in all are discussed. The silvical characteristics taken up are the size, growth, root system, crown, tolerance, wood, reproduction, range, soil, and association of each species. In addition, under a heading entitled ''General," the commercial importance, technical features, supply, common enemies, and management recommended, are given some atten- tion. The silvical characteristics are first taken up by descrip- tive words, or short concrete expressions or sentences under each heading. Then on a table they are shown in a comparative form by giving to each silvical characteristic heading three grades rep- resented by numbers. Thus under the heading "Growth" species of slow growth are designated by the figure i, of medium growth by the figure 2, and of rapid growth by the figure 3. Under the heading "Tolerance," the same figures represent intolerant, me- dium, and tolerant trees respectively, etc. The conception of the publication is good in that it attempts to bring together in concrete form for easy reference the main silvical facts in regard to these species. The publication is a compilation of data from various sources and similar to much other compilation work, it impresses the reader as not being en- tirely a finished product. This is without doubt due to a lack of knowledge of some of the species, to a lack of published knowledge of some of the others, but it appears to be due also almost unques- 440 Forestry Quarterly. tionably to not consulting carefully all available sources of data. Some contradictions appear in the publication and it is certain that a few of the statements will not stand the test of very care- ful weighing. Thus Elms in general are given as "tolerant" but each of the species as "intolerant." Nevertheless, the faults do not destroy the value of the work as a whole and it is quite commendable for a students' publication. C. R. T. A Study of the Growth and Yield of Douglas Fir on Various Soil Qualities in Western Washington and Oregon. By E. J. Hanslick. Mr. E. J. Hanzlik's manuscript report of 40 pages dated March 14, 1912, is of keen interest to all foresters, and hence receives here a very full review. The report covers a series of seven studies : (i) Yield tables for Douglas fir stands. (2) Mean annual growth and the rotation. (3) Site quaHties of Washington and Oregon. (4) Influence of aspect upon the density and growth of Doug- las fir. (5) Influence of density of stocking on growth and volume. (6) Comparison of yield on bench and bottom lands. (7) Methods of determining site qualities of Douglas fir stands. I. Yield Tables. The study was carried on in about thirty-five different localities, west of the Cascade Mountains into the Coast Range in Oregon, from the Canadian Line on the north to Cot- tage Grove, Oregon, on the south. The altitude of the territory covered varies from about 200 feet along the coast to about 2500 feet in the Cascade Mountains. This study aimed to include all types and qualities of stands of Douglas fir, providing they were even-aged, pure and fully stocked and under 140 years of age. Care was exercised especially in getting fully stocked stands, so as to obtain data which would approach closely to that which there is reason to believe will be Current Literature. 441 obtained when Douglas fir is placed under a definite system of management. For that reason, the yield shown, in the tables is higher than is attained now in the average run of Douglas fir in its present state of growth. The yield tables in this report indicate the average yield for each quality and not the maximum yield which can be obtained under very favorable conditions. Therefore these tables are very conservative on the whole and can be safely used after the conditions and quality of the site have been determined. In ap- plying the tables, it is very important that the quality of site be known, and in many cases this is a difficult matter to decide easily. Therefore, in study No. 7 there is a discussion concern- ing the question as to the determining factors. The data for these tables was secured by the method of stand measurements, consisting of ascertaining the size and number of trees per acre in even-aged stands of various ages. About sixty- one tracts', ranging in age from 24 to 137 years, were measured, in each of which from five to thirty-three sample plots, in size from one-sixteenth to one acre, aggregating 598 in all, were ex- amined. The diameter of each tree on the plot and the heights of a few of them were measured and the data systematically tallied. The tables were derived by applying volume tables found in Forest Service Circular 175 "The Growth and Management of Douglas Fir in the Pacific Northwest" by T. T. Munger, to the actual sample plots measured in stands of various ages, and the results read from evened-off curves. The yield in cubic feet in- cludes the contents of the whole stem of all trees ; that in board feet includes only the merchantable contents of the trees which are 12 inches or more in diameter breast high. 442 Forestry Quarterly. -^ be X ^ < Tj- i^ vr, \J-.

B. H. 2. The Mean Annual Groivih and the Rotation. The mean annual growth of Douglas fir varies considerably for each quality. On the Quality I sites, the mean annual growth ranges from 413 feet B. M. per acre at 40 years of age to 1,013 feet B. M. at no years of age. At this latter period the growth culminates, decreasing therefrom to 965 feet at 140 years. In cubic volume, the maximum volume production is attained at the age of 50 years, at the rate of 181 cubic feet per year. The decline in the mean annual growth is very slow, decreasing only a few feet each year, so that at 100 years the rate of growth is only 6 cubic feet a year less than at 50 years. Therefore for a stand which is to be managed on a cubic volume rotation, such as for cordwood, pulp wood, etc., it is seen that a rotation of from 50 to 70 years might be best, depending much upon the quality of the product desired. For Quality II soils, the mean annual growth in board measure varies from 300 feet per acre at 40 years to 673 feet at no and 120 years. After this period the growth decreases gradually to 653 feet at 140 years. For this quality, it is recommended that, silviculturally, a rotation of no years be used, with a mean an- nual growth of 673 board feet per acre, making a total stand per acre of 74,000 board feet. For a cubic volume rotation, the culmination of the mean an- Current Literature. 447 nual growth is at the age of 55 years, at which period the growth is 147 cubic feet a year. After this age, the decline is very gradual, allowing a rotation of from 50 to 60 or 70 years, ac- cording to the quality of the products desired. On Quality III sites, the mean annual growth in board feet culminates at the age of 115 years, giving a growth of 505 board feet per year, making a stand per acre of 58,000 feet B. M. This period may be considered as the silvicultural rotation of Douglas fir stands on the poorest quality of soils. Taking the cubic volume, the mean annual growth culminates at the age of 50 years, with a rate of growth of 113 cubic feet a year. The decrease is gradual from this period, making a rota- tion of from 50 to 60 or 70 years possible. In the following table (No. 6) is given the length of rotation, the mean annual growth, the stand per acre, for the different soil qualities. TABLE No. 6.

A Study of the Site Qualities of Washington and Oregon. In this discussion an attempt is made to classify the soils of Oregon and Washington into different site qualities on the basis of the cubic volume of Douglas fir stands. In summing up the question of sites, the following conclusions are reached: 1. In the State of Washington about one-half the Quality I sites will be placed under cultivation for agricultural crops ; in Oregon much of this quality is absolute forest land. 2. The Quality III sites in both states will always remain as true forest land. 3. The Quality II sites both in Washington and Oregon will only in part be turned over to the raising of agricultural crops. 448 forestry Quarterly. 4. The better qualities are for the most part a medium to deep loamy soil, with a mixture of sand or gravel. 5. The poorer qualities occur upon soils, for the most part, either a shallow or very shallow sand with a rock subsoil, with much outcropping rock. 6. The best quality sites in Washington occur below 1000 feet elevation; in Oregon below 1700 feet; both in the region of great- est precipitation and most even temperature. 7. The poor quality sites occur above 1200 feet in Washington ; in Oregon no doubt at much higher elevations. 8. The medium or second quality sites are found at interme- diate elevations' between the best and the poorest qualities. 9. Douglas fir is found mainly in pure stands either on bench or slope lands which are well drained, while the poorer drained bottom land stands contain a mixture of Hemlock and Cedar with the Fir. 4. The Influence of Aspect upon the Density and Growth of Douglas Fir. In general it has been noted that stands with cer- tain aspects appear to be either more or less densely stocked than similar stands situated on different aspects. The study shows that this is actually the case, and not only is the density of the stand afifected, but also that the cubic volume, the board-foot vol- ume, the basal area, and the diameter growth are affected. 1. A south exposure bears the densest stocked stands; a north exposure bears the least densely stocked stands. 2. The trees on a north exposure have a greater diameter growth, and the growth in cubic feet and board foot volume ex- ceeds that of other exposures. 3. The trees on a south slope, having a smaller diameter give a larger basal area in square feet than those on other exposures. 5. Influence of Density of Stocking on Growth and Volume. In order to attain the maximum yield in bpard measure, it is de- sirable to thin out most of the smaller, suppressed trees and thus give the larger ones a chance to attain the best development pos- sible under the conditions. Mr. Hanzlik illustrates this with two otherwise similar tracts located in the Coast Range. Both are on Quality I sites and Current Literature. 449 show a maximum of cubic volume production. The tracts are, however, at different elevations. The Glenada tract contains a very dense stand of trees while the Saddle Mountain tract seems to be about normally stocked, though somewhat below the aver- age stocking for that age. The figures shown are for the average of ten sample acre plots in each case. TABLE No. 7. Effect of Density on Yield. FOR ALL TREES. FOR TREES 12" OR MORE IN D. B. H.

The most noticeable eft'ect of the overstocking is that the Saddle tract with nearly 50% less trees per acre than Glenada nevertheless has a larger average D. B. H. and only 13.6% less yield in cubic feet. Still more favorable to Saddle is the com- parison of trees 12 inches D. B. H. and over, for Saddle has 90 trees, Glenada only 75 and the cubic volume of these stems in Saddle is 29% greater than in Glenada; the board foot volume 42% higher. This is because on the Glenada tract only about 15% of the trees are 12 inches or over, D. B. H. while on the Saddle tract 32% are of merchantable size. Accordingly, density is a prime factor in the development of Douglas fir stands, especially where the largest quantities of saw timber are desired at the earliest possible time. In agreement with the Austrian experiments by Bohdannecky and Schiffel, and the Russian plantations of Douglas fir by Dr. Schwappach, Mr. Hanzlik reaches the following conclusions in re- 450 forestry Quarterly. gard to the present stocking of Douglas fir stands in western Washington and Oregon: — 1. The immature stands contain from 25-50% too many stems. Heavy thinnings are necessary for increased increment and will give a fairly good money return, at the same time benefiting the stand silviculturally. Stands on the better quality soils require very little thinning after 70 to 100 years of age. 2. Mature stands of the better qualities are probably very little overstocked ; on the poorer qualities the stocking is too heavy due to an excessive number of trees under 12 inches D. B. H., which no doubt retards the growth of the larger trees. 3. In even-aged mature stands (over 100 years of age) of the first quality a stocking of about 100 trees per acre at maturity will produce the greatest yield in board measure as practically all the trees in the stand are of a merchantable size (12 inches or more in D. B. H.). 6. Comparison', of Yield on Bench and Bottom Land. The con- clusion is reached that land which is considered as first class agri- cultural soil will not always yield as large a forest crop as land which is classed as inferior for agricultural crops. Mr. Hanzlik also shows that Douglas fir makes its best growth on a slope rather than on level land and that one of its requirements is that the land be well drained. 7. Methods of Determining Site Qualities of Douglas Fir Stands. Mr. Hanzlik compares the four chief methods of de- termining site quality: i) by optical inspection. 2) by the use of the height growth of the dominant trees, 3) by the growth of the stand in cubic volume, 4) by the density factor (based upon the assumption that the height, basal area and the age of a stand are related by a constant factor). Except for some slight discrep- ancies, this factor agrees with the site quality as determined by the growth of the stand in cubic volume. The factors are be- tween 200 and 500; for division between Quality I and Quality n 400 is an appropriate number, while 300 separates the second quality from the third (on scale of five qualities H-HI and HI-V). Dr. Adam Schwappach has briefed Mr. Hanzlik's report in the October, 1913, number of the Zeitschrift fiir Forst-und Jagd- Current Literature. 451 wesen* and has converted the yield tables into metric measure. He comments on the great height growth and comparatively poor volume production which these tables' show. He calculates (volume in cubic feet \ — i — r—. — : — z ; I for all height m feet x basal area / trees at 140 years of age and finds the factor to be .32, .35 and .37 for the three site qualities respectively, which is very low. This, Dr. Schwappach attributes to the volume tables ; Mr. Hanz- lik himself says' that his volume figures are very conservative. Furthermore, as Dr. Schwappach points out, the tables are for final yield only and do not take into account the intermediate yield from thinnings which, in Norway spruce, aggregate about 50% of the total production. Even allowing 20% increase over Hanzlik's final yield figures to allow for trees dying out, the yield of the Douglas fir is only 20% greater than that of Dr. Schwap- pach's own figures for Norway spruce, Site Quality I, age, 120 years. Comparing Hanzlik's figures with the latest Saxon yield table for spruce, printed in F. Q., Vol. XH, No. i, p. 114, one finds at age 100 years for Site Quality I : — Douglas fir, 17,600 cubic feet per acre. Norway spruce, ...14,915 " " — an increase of only 17% over the Norway spruce. Assuming the stand- form-factor to be the same at 120 years as that of Norway spruce — i. e. .44 — and using the values for height and basal area as given in the table, the yield becomes for 120 years, 27,880 cubic feet as against 20,700 cubic feet per acre. "One sees, therefore," says Dr. Schwappach, "what an influence the method of volume determination has and how carefully the data must be analyzed before the American figures can be used as a comparison with the production of German species — in this case with the production of spruce and fir." Dr. Schwappach concludes from Mr. Hanzlik's figures that the plantations of Douglas fir in Germany are yielding, at least in youth, just as much as similar stands do on their native sites. A. B. R.

A brief summary of the results of investigating several thou- sand beams in buildings, more than one hundred of which were "examined chemically and microscopically." The pamphlet deals exclusively with southern yellow pine timbers, since this wood is the only one now used to any extent in the East for heavy mill frames. Attention is called to the great confusion in the commer- cial names used to describe the southern yellow pines, and to the indefiniteness of some of the terms used in rules for the inspection of timbers. The difficulty of identifying the various southern yel- low pines is also brought out. After discussing briefly the various causes of dry rot and the influences which encourage it, the pamphlet mentions some of the preservatives which have been used to arrest decay. The following observations are made : 1. "The percentage of resin in hard pine can be taken as an index of its power of resistance to dry rot. 2. "Hard pine lumber 12 inches square or larger is practically not obtainable with sufficient natural resistance to withstand fungus in a moist atmosphere. 3. "The non-resinous and sappy hard pine, which is obtainable is not safe to use for the important parts of a building without antiseptic treatment. 4. "Holes through columns, narrow spaces between beams and hollow spaces in floors or roofs are of no value in preventing dry rot, and serve to rapidly spread it to all susceptible material. 5. "Heating a new building to 115° F., for twenty-four hours, or more, several times has a value well worth its cost in preventing serious dry rot damage. 6. "Of the various antiseptic treatments in practical use at pres- ent, corrosive sublimate appears to be the best adapted to mill timber. Modification of the present process may be necessary when deeper penetration is required." R. C. B. Current Literature. 453 Annual Fire Report, ipij. California State Board of Forestry. Sacramento, 1914. Pp. 94, illus. This is a review of the forest fire situation in CaHfornia during the past year. The State Forester points out that his office must rely upon Federal Forest officials for reports on fires in the National For- ests and upon 1,300 voluntary unpaid fire wardens for all reports of fires outside of the National Forests. The latter class of men fail to make reports, hence the statistics given probably do not come very near the actual truth so far as the whole State is con- cerned. The year 1913 appears to have been more unfavorable than any for some time past, a total of 559,370 acres being burned over at a loss of $511,077. The reported acreage burned during 1912 was 156,241 acres with a loss of $31,906. The most unfavorable months for fires are September, August, July and October. Several pages are devoted to a description of a few average fires which occurred during the year 1913. This is followed by a discussion of protective associations operating within the State ; the character of assistance rendered by the Federal Government and to proposed legislation.

A Naturalist in Western China. By E. H. Wilson. London, England. 1913. 2 volumes, pp. 251-229. The writer of these two volumes has made four separate ex- peditions, covering nearly 11 years since 1899, into western China, for the purpose of collecting botanical specimens and plant in- troductions. The first two explorations were in the interest of the well-known house of Veitch, and the last two for the Arnold Arboretum. An introduction by Professor Charles S. Sargent, of 37 pages, contrasts the forest flora of eastern continental Asia with that of eastern North America. According to this, in general, the American trees are larger and more valuable than the related Chinese species ; while the shrubby members are less showy. The 129 natural families represented in the two regions are dis- cussed in detail, and a very interesting comparison made as to representatives of each in the two areas. Reference may be made to the Coni ferae, which is represented in China, by 14, and in eastern North America by 9, genera. China lacks the Tax- odium and Chamaecyparis of eastern North America, while the genera Libocedrus, Cupressus, Cunninghamia, Pseudolarix, Kete- leeria, and Eokienia have no eastern American representative. In eastern North America 15 species of Pinus occur as contrasted with 8 in eastern Asia. In Picea and Abies, however, the advan- tage lies with China, with 20 and 9 species respectively, as against 3 and 2. The numerical representation in the remaining genera is approximately equal. Summing up, of the 129 families, 92 fami- lies are common to the two regions; 12 occur in eastern North America, not in eastern Asia ; and 25 occur in eastern Asia not in eastern North America. Owing to the greater variety of topo- graphy the forest flora of China is richer in genera than that of eastern North America. Of the 692 woody genera in the two regions, 155 are common to both; 158 are found in eastern North America and not in eastern Asia, and 379 occur in eastern Asia and not in eastern North America. Of the tropical genera, y6 have reached Southern Florida, and 89 southeastern China. It is concluded that the number of species of trees and shrubs is proba- bly nearly equal in the two regions. The first volume is largely an account of the various journeys, Other Current Literature. 455 with special reference to the manners and customs of the non- Chinese races inhabiting the China-Thibet region explored, but much botanical information accompanies the narrative. The bulk of the material of botanical interest, however, is to be found in the second volume. The nature of this is indicated by the following headings : the flora of western China ; the prin- cipal timber trees ; fruits, wild and cultivated ; Chinese materia medica ; gardens and gardening ; flowers cultivated ; principal food-stuff crops ; trees, shrubs and herbs of economic importance ; tea and tea-yielding plants, and the tea industry.

Of the 368,000 acres of forest on the Forests island over half is commercial, less than of a fifth private forest, and 30 per cent is Corsica. State Forest (French) and under good ad- ministration, accessible by excellent road systems constructed during the last 50 years. Neger enthuses particularly over the coniferous mountain forest. From the sea- shore to about 3000 feet the characteristic Mediterranean tree flora, called macchia, prevails, composed of a variety of broadleaf trees and shrubs of little economic value. This is followed by a narrow belt of open chestnut forest, Castanca vesca — the chest- nut and olive being the most important food trees of the island, hence this region having the densest population — sometimes up to 4000 feet, old veterans of over 1000 years old being not rare. Above the chestnut zone, up to 4500 feet, the conifer forest ex- tends, while strange to say the timberline is formed by a broadleaf forest, in which the beech (up to 100 feet high) is the dominant species and Abies pectinata its concomitant with Betula verrncosa, Alnus cordata, Ilex aquifolium. Neger explains this peculiar, un- expected distribution by the absence on the island of the northern timberline conifers, the coniferous forest below being made up of the Mediterranean species Pinus pinaster and P. corsicana with Abies pectinata. The pines show a magnificent development, diameters going sometimes up to 5 feet and heights to over 150 feet. The two pines are not easy to dififerentiate without cones except by habitus, the Corsican pine remaining pyramided to old age and presenting a clear bole, the Pinaster pine assuming a rounded crown and remaining branchy. Seed production is very plentiful hence natural regeneration easy. Although the stands appear a picture of health, fungi are not absent, and mistletoe is sometimes unusually developed.

The Venetians and Romans once drew supplies of timber from that region, but now there is little left. In many places bare mountains of stone occupy regions of former forests ; but the people are planting trees and trying to make them grow. One of the common methods is to blast holes for the trees with dynamite and carry soil to fill the pit. Some places have be- come covered with green vegetation in two years. No grazing is permitted at first on newly planted mountain slopes. Sheep are the first animals to be admitted to these new pastures, the year following cattle are admitted, and finally goats when the shrubbery is high enough to care for itself. Parallel plots of these reserves are laid out over the province, so that when one plot is entirely reserved, the next plot is open to sheep, the third has sheep and cattle, and in the fourth, sheep, cattle and goats graze together. Very strict forestry laws exist and violations are subject to imprisonment. Instead of jailing the men, however, they are used for forest work. Hardwood Record.

It requires, however, experimentation to find out how far the ef- fect of the parasite goes, to determine whether this biological method of fighting the disease may become practical.

Russian investigators are active in try- Forest ing to establish the truth of the influences Influences. of forestcover. The forestal significance of the retention of precipitation of crowns is under discussion in the Journal of the St. Petersburg Foresters Society. Five year observations show that in a pine forest of .6 to .7 density 23% of the precipitation was retained by the crowns; of snow 12 to 15% was so retained. In the majority of cases (50% of the rainy days) from 26 to 50^ remained in the crowns ; the lighter rainfalls, which are more frequent, na- turally are retained to a greater extent. With regard to snow the wind plays a role ; the severer winds benefiting the soil by larger masses being deposited, while rain is more rapidly evaporated and lost to the vegetation. A technical expertise regarding the devastating floods in Trans- caucasia, especially on the southern slopes, which annually de- stroy millions of property with loss of life, states the affected water basins as 13 142 square werst and estimates the needed preliminary expenses for reboisement work at over $8oo,ocxD.

Natural In a thoughtful article, Forstmeister Regeneration. Lieber develops his ideas on natural re- generation, which he summarizes in the following rational prescriptions : 1. Preparation of stands for natural regeneration must be be- gun in early youth by means of thinnings in such a manner that a special preparatory felling is not required and so that richer or poorer seed years find a larger part of the stands ready for the reception of seed. 2. The decision whether regeneration is to be begun depends on whether sufficient desirable volunteer growth is at hand; and its' development dictates the progress of fellings. 3. The fellings are to be conducted not only with reference to the needs of the young growth but with regard to the best utili- zation of the old growth. Both considerations have equal rights ; the "ripeness"' of the trees to be removed must be determined. 4. Keeping foremost in mind the object of the management to secure highest yield the desire to form a certain stand in form and kind must be kept in the background. Change in species and form one must not fear because of a preconceived plan. 5. It is equally justifiable to finish the regeneration in a short time as to extend it over a long time as considerations sub 3 in- dicate. The transition to a selection form or to the real selection forest may in some places satisfy the needs. 6. Consideration of yield regulation must not deter the choice of a method of silviculture which is difficult to regulate if better yields can thereby be secured. Yield regulation is a servant of 470 Forestry Quarterly. the management, it must not become the master and demand forms, because they are easier to obtain or to judge. Ueber naturliche Verjungung.

On poorer sites, natural regeneration remains poor, so that, if no thinning is done (which is expensive) in 50 years only bean and hop poles are found, and at 30 years stands are hardly over man- height, while 10 year old plantations side by side have reached that height. He recites the disadvantages of natural re- generation on poor and medium sites ; enormous loss in incre- ment ; loss through poorer values of the wood product ; great cost of cultural measures to remedy these defects ; more punky wood due to injuries received in gradual removal of timber and reduction of workwood per cent; execssive cost in moving ma- terial from seeding area which alone would pay for planting.

The final measurements were made in 1912 when the stand was 70 years old, by the method of sample trees, due attention having been paid to stem classifica- tion. The results agree with what other investigators have found. Severe thinnings are most effective ; they do not curtail the height growth, but on the contrary stimulate it more than the other two degrees. In total production the c-grade furnished 22.7% more than the a-area, and 15.6% more than the &-grade. It appears, however that the three areas were not equally stocked at the be- ginning, which vitiates the value of the figures. The severe thin- ning did not lengthen the crown but on the contrary shoved the crown up in proportion to the great height growth; the crown diameters also show great regularity in gradation, as appears from a comparison of branchwood to bole wood, the boles being also more cylindrical.

Details of the methods followed are described. The firing is usually done during the winter months, the object being "to keep the fire line moving regularly and evenly down hill." The article concludes with an account of the damage to a tree crop, under- growth and soil cover, and the writer summarizes the experiments as showing "most conclusively that, except in regeneration areas, woods can be fired on a larger scale without doing appreciable damage to the Chir." It is recommended, however, that the selec- tion system be abandoned for these areas, and that a uniform system be adopted as being more suitable, since the regeneration could then be protected more systematically. It is argued that there is no reason why forests where trees are tapped for resin should not be similarly burned provided the bases of the tapped trees are first cleared of needles and grasses, as is now the practice on the Florida National Forest in the United States.

The comparison is most flattering to the estimator, for while the ten positions figured on actual returns show on the average an increment of 58 cu ft. p. acre (varying from 49 to 71), the estimate averages 55 (varying from 50 to 64) cubic feet per acre. 4/6 Forestry Quarterly.

Professor Dr. Wimmenauer reports in Financial great detail and with ample tabulations Aspects results of experimental thinning in the of dominated stand at the station of Hesse, Thinnings carried on within the last 25 years, some 17 areas for pine and beech on plots of two-thirds to two and a half acres being reported. The inquiry was directed not merely to volume but to value production. For the latter to overcome the difficulty of dividing into assortments a value meter (Wertmeter) calculation was introduced. For beech, where at the age of 79 years workwood is as yet not developed, the value meter was determined by assuming brushwood to be Jialf in value of timberwood, hence if there were 60 fm of the latter and 40 fm of the former, this would give 80 zvm, value- meter. For pine the calculation was made differently. Since the relation of assortments in a stand is primarily dependent on the mean diameter of the stand, the assortments corresponding to each such diameter were ascertained and their values in the local market ascertained (since only relative values are to be deter- mined), and then a quantity of wood of the value of 10 Mark was accepted as valuemeter. For illustration : to a 40 cm diam- eter corresponds 40% of sawtimber at 22.6 mk, 40% of building timber at 17.1 mk 10% fuel wood over 3 inch at 5.3 mk and 10% brushwood at 0.6 mk; this makes the average value 16.5 mk. Such a tree would then contain 1.65 value meters. The results are somewhat unexpected and disappointing. The beech areas show that total volumes as well as increment per cents under a, h, and c, i. e. light, moderate, and severe thinnings in Periodical Literature. 477 the understand (par le has) vary irregularly and differ very little, while in d and e, i. e. thinnings in dominant and selection thin- nings which were made in a few cases did not show much better. The total average showed Thinning degree a b c d e Valuemeters 100 98 102 106 92 Increment per cent 4. 4.1 4.5 4.5 4.9 The thinnings in the subordinate stand of pine showed also no tangible result, the increment per cent for a, h, and c thinnings being 4., 4.1, 4 respectively, the volumes 96, 100, 96. A much more satisfactory experiment with different methods of calculation was carried on by the author independently in beech. The procedure started with the thought that a thinning produces two effects: an increase of increment on the remaining stand which is expressed by the difference of the increment per cent of the thinned stand {s) and that of the unthinned main stand (3') ; and on the other hand, an earlier money income which can earn interest (p) instead of the increment per cent (x) of the subdominant stand of the unthinned stand, so that, if the original dominant stand was H, the thinned stand D, a precise financial expression of a thinning would be: ^^=H(c — y) -{-D (p — x). In practice, recognizing five stem classes, the per- formance of each of them would have to be ascertained and the sum found. The three experimental areas were thinned every 5 years, alto- gether 5 times (original ages 6y, 67, 63), the first one, with thin- nings in the subdominant, tree classes I-III ; the second, by selec- tion thinning, tree classes III-V; the third one by thinning in the dominant, tree classes II-IV. A fourth area lightly thinned was used to determine increment per cents 3; and x of the form- ula, while the increment per cent s of the thinned stands was for each stem class in each area calculated from the 20 year period. The following results appear. Stem class I II III IV V X or y 3 2.2 3.3 3.6 3.8 2: in area 1 1.2 2.1 3.6 4.3 3.9 z in area 2 2.4 ^.6 3.8 3.5 3.1 z in area 3 1.5 3.6 4.6 3.9 4.1 4/8 Forestry Quarterly. The different kinds of thinning exhibit characteristic results. After moderate thinning in the subordinate stand the stouter stem classes benefit generally more. In the selection thinning ir- regularity is striking. In the thinning par le haut the maximum increment comes to the middle class III. Nevertheless, the in- crement per cents of total volume are little different, as in the previous case, varying only as 3:3.7:3.4:3.6. Applying now the ascertained data to the formula and choosing p=3, the final result makes the three different kinds of thinning as 152. i : 75.2: 147.8. That is to say the selection thinning is financially only half as effective as the other two kinds, which are pretty nearly alike in their results. The second object of thinnings, the money interest instead of wood increment, is particularly advantageous in the thinning in the subdominant, not so in the thinning par le haut, and least in the selection thinning. The increase in increment on the main stand appears as 86: 113 : 129 for the three kinds of thinning. The author believes to have proved that in the statistics of thinning practice only exact calculations yield reliable results. Diirchforstungsversuche in Buchcn-und Kiefernbestanden.

Kiinkele in a very elaborate article of Determining 50 pages develops a method of evaluating Value the value increment per cent of standing Increment trees, as well as stands, which should be sufficiently accurate and at the same time simple. The article is divided into five parts : Influences deter- mining wood prices ; mathematics of price curves ; value incre- ment of single trees ; value increment of stands ; helps and ex- amples of the use of the new formulae. In the first part some interesting data are brought showing, that length of log influences the price only of small sized sticks essentially [masts? Ed.] ; quality of wood influences price more than length, especially in pine and that increasingly with size ; but by all odds the greatest influence on price is exercised by diameter, increasing up to a cer- tain size which varies with species. A table giving prices for 24 species paid in the Baden State forests exhibits the precise variations. An idea of the relative value of species may be Periodical Literature. 479 gained from the diameter which in different species command a price of 20 cents per cubic foot (cut logs) : black locust 6 inch; ash, 10 inch; walnut, 11 inch; oak, 13 inch; basswood and maple, 15 inch; pine and larch, 16 inch; elm, 17 inch; beech, 24 inch. Translating the price per cubic meter into approximate values per M ft B. M. for 12-16 inch logs, cut in the woods the following prices are found : ash and walnut, $44 ; oak, $27 ; basswood and maple, $25; pine and larch, $22; elm, $20; poplar, $21; birch, $18; chestnut, $17; spruce and fir and beech, $16. Different species show then, different price movement per unit. In oak, while length does not vary the price more than 15% at most, the diameter may vary it by 1700% over the smallest diameter (6 inch). Here fame plays a role, oak of the Spessart commands three times the price of logs in other forests. In beech the influence of diameter may increase price by 300% ; in other broad leaf species by 400%, the rise beginning only with medium diameters. Spruce and fir show price increases for length in different size classes varying from 3 to 35%, for quality from 10 to 21%, but for size up to 200%. In pine the price rises with the diameter up to 500%, so that while the smallest logs bring 8 cents per cubic foot, the largest may bring 40 cents. It is also interesting to note that the cost per cubic foot of making logs averages for all kinds and sizes just about i cent (about $1.25 per M ft. B. M..) which means i to 10% on the final value ; and transportation from the woods to the woodyard averages for all German forest product 4 cents per cubic foot. This influences the prices in the forest by from 2 to 20%, and that all assortments alike. Market price increments in the last decade for beech pro- gressed regularly 1% annually, but oak 3 times as much and in some places over 4 per cent annually for medium sized logs (16-20 inch middle diameter). Oak has experienced such con- stant price increase in the last decade, especially in the Spessart mountains so that "the sum of all increments in spruce cannot measure up to the mere price increment of oak; in other words, the oak in the woodyard unused brings better interest than the spruce in the forest. The mathematics of the price curve is then developed in great detail with the use of calculus, and after critical reference 480 Forestry Qtuirterly. to other formulae (Schumacher's rule) the author's own formula is constructed, not quite so simply as the author promised. The upshot of it is that Schumacher's rule, "the values per unit rise with the diameters in arithmetic progression," is only partly true, the curve being represented by a number of straight line parts; which by shifting of the abscissae zero axis to a determinable degree can be made straight : the prices then are in direct propor- tion to the clianged diameters. The amount of shifting {s) for different diameter classes {D to d) is capable of mathematical D—d expression ; being for straight lines s=^P — 5 D when P and p are the prices for the two diameters ; and for curved parts, Ax To determine the price increment per cent, Pressler's well known diameter increment per cent formula, somewhat modified, 200b namely Pcfr=r-=— — z—, in which «= number of vears for which D-^-nb the investigation is made, and &=average periodic ring width, 200b during n years, is modified to -^fir-, — r— . This holds if the mea- * -^ D-\-nb-\-s surement is made in the middle of the log length, for measure- ment at other places, the coefficient 200 must be varied; if breast high, to 240 or 300 for .8 and .9 density (change of form factor!), and if measured at Pressler's "increment middle" to 160 and 130 respectively for the two densities. Going into the discussion of the value increment of a tree, the author reviews the various methods hitherto employed, and then develops his own formula starting from the conception that this increment is composed of the increment i. of the log volume (^'^) times unit price (g^), 2. of volume of other wood (z/^) times its unit price {q^), 3. of the participation of the log volume in the total volume {x) or in the total value (^r) in hundreds of the unit.

These are summarized as follows : On "gres vosgien" soil, with a rotation of 135 to 144 years, the average production during the past ten years was 80 cubic meters per hectare (1145 cubic feet per acre) or a growth per cent of 25; in stands partly on "gres vosgien" and partly on "gres bigarre" soil the production was also 80 cubic meters per hectare for 10 years, or 27 per cent. In the second case, the rotation was 144 to 150 years. On granite soil with a rotation of 144 years the production was 70 cubic meters for 10 years, (1000 cubic feet per acre) making 21 per cent. T.

Two well guyed trees or gin poles, one Log-Loading on each side of the track and 200 to 400 Device feet from it, have a li inch cable stretched tight between them 40 to 60 feet above ground. A special carriage that can be racked in either direction at the speed of about 800 feet per minute, rides this line. The lifting line and this carriage are operated by a 3-drum, 4-cylinder loader. The lifting line, handled by the lower drum, is fastened as a tail-hold to one of the guyed trees and then passes through the two lower sheaves of the carriage, looping down to a special block in the bite of this line. This gives the engine a block purchase on the log. The lifting and racking lines are handled independently. The advantages of this system are : ( i ) no roll- way or landing place is needed; (2) the landing is never blocked up, for the logs can be delivered by the yarder anywhere between the track and the guyed tree 400 feet away; (3) any log can be picked up to make up a load; (4) timbers 160 feet long are handled; (5) it is a safer system than any of the old ways; (6) Periodical Literature. 483 a greater choice of settings for the yarding engine is afforded; (7) the machine can also be used to spot cars. American Lumberman, January, 1913. The village of Liverpool, N. Y., with its Basket Willow 1400 inhabitants, was the first place in Business this country to start the manufacture of in willow baskets. About 50 years ago the Nezv York State. Germans there made baskets from willow for their own use around the home, and from this the demand grew to some 350,000 baskets annually at the present time, with shipments all over the country in car-load lots. Almost every family is now engaged in either raising the willow or cleaning it, or making the baskets. Raising willows was formerly restricted to the back yards, and almost every German had a small patch, but now some farm- ers make it a business and have 40 to 60 acres of them. Cuttings are set about a foot apart and from each a cluster of 40 to 60 rods will grow annually after the third year. Considerable care is required to keep up good yields: the ground must be kept free of weeds ; when cutting, the rods are clipped close to the ground ; moist soil, although not necessarily swampy soil, is needed. When full grown, an average yield is about 3 tons of rods per acre each year; and they are worth about $18 per ton, green. The rods are 3 to 5 feet long usually, although some reach 8 or 9 feet ; the latter are not much in demand. After the willows are cut, they are steamed and the bark peeled off by hand, and the rods sorted into 4 or 5 sizes. It is dirty work to strip willows of their bark for they are slimy and wet. The peelings are "thrown into the back yards, and when they will hold no more they have to pay to have them carted away. No use has been found for the bark. No machine has ever been invented to strip willows successfully. There are 150 basket factories in Liverpool, all doing hand- work. Almost every basket-maker has a shop in his house. One man can make 5 hampers a day or a dozen waste-paper baskets, and all of the work is done by the piece. Formerly 15 hours constituted a day, but now the hands work "only twelve hours." 484 Forestry Quarterly. The average wage for the basket-maker is $1.75 to $2.00 a day. Labor conditions are peculiar in that "no one is learning the trade," and as a result hands are scarce and they do about as they please, although many work all their lives in one factory. There are four sizes of hampers made; clothes, market, office baskets, and cat and dog baskets. Some years as high as 35,000 clothes baskets alone were made. The Barrel and Box. 1912. As a rough estimate there are about History 1000 veneer establishments in the United of the States, using approximately one-half bil- Veneer lion feet of lumber yearly. There is an Industry. annual production of veneer in 34 States ; the leading States are Michigan, Indiana, Illinois, Arkansas, Missouri and Wisconsin. Practically every kind of wood is used ; the leading ones in the order of prominence are gum, yellow pine, maple, poplar, cottonwood, oak, birch, elm, basswood and beech, besides foreign woods in less amounts. There is evidence of veneer cutting in one form or another back as far as history goes ; but those early efforts were hand- work and have little connection with modern veneer making. The use of fine face veneer in cabinet work seems to have started with Sir Ishambard Brunei in 1799 at the Chatham dock yards'. Here he had the first steam saw-mill in England. He equipped a shop at Battersea about 1805, and developed the practice of sawing veneer from mahogany and rosewood. About this time he invented the veneer-saw, pretty much as we know it today, and cut veneer as thin as 1/16 inch with great precision. Since that time there have been many veneer cutting machines invented,all of which may be classed under three heads : sawing, slicing and rotary cutting or peeling. The rotary veneer cut- ting industry was just attaining importance in the woodworking world 15 to 16 years ago. About that time there were some pre- tentious experiments tried at making built-up lumber, which proved unprofitable. The origin of the rotary cutting is obscured a little, but some of the old writers claim, without clear references however, that it originated in Russia. The best data seems to give Gen. Bentham in England credit ; for the rotary method Periodical Literature. 485 might logically develop from a power planer that he built. This machine had some resemblance to a huge hand plane mounted on slides, power driven, which in operation sliced thin pieces from a block of wood. The pieces were used at first for making light packages (hat-boxes). From these machines the modern basket factories developed, and since they had a greater capacity than was needed to supply the basket demand, the natural step for some outlet was the development of the plain veneer and the built-up lumber industry. St. Louis Lumberman, December, 1912. Australian hardwoods such as karri and Block Paving iarrah, also the so-called Canadian red- in wood and Baltic redwood, are used for England paving-blocks in England.

The standard wood for cigar boxes is Cigarhox Spanish Cedar. It is supposed that this Wood. cedar has a beneficial effect on the flavor of high grade cigars, although nothing definite can be said of the effect a box made of balsam fir, for example, would have on the cigars packed in it. The increased cost of the cedar has brought many substitutes into the market; where a solid cedar box formerly cost 7c now it is iic. The 486 I'oicstiy Quaitoiy. substitutes, other than veneers of the cedar, make a cheaper looking package, and the dealer knows that the cigar will be judged to a considerable extent by the box in which it is packed. The principal substitutes are veneers of the cedar or basswood or gum, basswood stained without veneering, or covered with paper printed to resemble the grain of cedar. Many combina- tions are used. One box may have a solid Spanish cedar top ; the sides of gum stained on the inside and veneered with cedar on the outside ; the ends unstained gum but veneered with cedar on the outside; the bottom of soft elm stained a cedar color. Most of the material is re-sawed to ^ or 3/16 inch thickness. The cedar veneer is cut i/ioo to 1/40 inch thick. American Lumberman, November, 1912.

The results of four experiments carried Douglas out on a commercial scale to determine the Fir value of distillates from Douglas fir Distillation. stumps, along with other supplementary investigations, show that distillation as an aid for clearing land is entirely out of the question, according to G. M. Hunt of the Forest Service. The processes employed were steam distillation with and without subsequent extraction, destructive distillation, and combined steam and destructive dis- tillation. The experiments are described in detail in a 3,000 word article, and the summary brings out a comparison of the yields of Douglas fir to those of Norway pine and Longleaf pine, although not an exact comparison. Turpentine Other Oils Tar Rosin Douglas fir 1-4 gal. 3- 8 gal. 15 gal. 75-150 tbs. Norway pine 8-18 " 10-20 " 300 " Longleaf pine 10-20 " 7-16 " 25-45 " The yield of charcoal is about the same for each. While the yields of acid and alcohol cannot be compared, those from Doug- las fir are so low that it is doubtful if they could be profitably saved. Besides' the small amount of product, other things stand in the way of profit. The products are different from those of Norway and Longleaf, and are not favored on the market. The large stumps make expensive handling, and, besides, the mill-waste is more easily handled and is much more than sufficient to supply the Pacific Coast demands, even if the market would take kindly to the products and all of the eastern materials were driven out of competition. Timberman, April, 1914. 488 Forestry Quarterly. By far the greater quantity of excelsior Excelsior. is made from small, second-growth bass- wood and poplar, although considerable is made from cottonwood, balsam, spruce, and willow. The wood is usually cut in 4-foot lengths, and peeled in early spring. The peeled wood produces cleaner excelsior and dries quicker. Poplar (probably Aspen) requires a year to become thoroughly seasoned. Green or damp wood is unsatisfactory because it clogs the ma- chinery and is apt to become mouldy when pressed in bales. After the wood is seasoned it is cut square ended into 16-inch lengths. Open air seasoned wood is preferred to kiln dried. There are two classes of machines : an upright double-head machine and an 8-block horizontal machine. Both are adjustable for different grades of excelsior. Excelsior is usually cut from 1/32 inch to 1/8 inch wide and about i/ioo inch thick; these machines can however, be adjusted to cut from 1/64 to 1/2 inch wide and from 1/500 to 1/50 inch thick. The double upright machines require about 5 horse-power each and have a capacity of I ton per day, that is approximately i cord of 4-foot wood. The horizontal machine cuts about 5 tons per day. Excelsior is selling at $18 to $22 per ton and the finer wood- wool at $30 to $35. The cost of production varies for $3 to $5 per ton. Many of the large consumers have plants of their own. The best grades of excelsior are made from basswood. That not more of this is used is due probably to its scarcity and to the high price of the stumpage. Cottonwood is the favorite excelsior wood, contributing 43.3 per cent of the total amount consumed. It was used by manufacturers in 18 States. — U. S. Bureau of Census Report for 191 1.

It Budget. is marked by increased receipts and ex- penditures along most lines, as for many years. For the state forests, an area of 7,518,159 acres, (or 6.7 million productive) receipts and expenses are estimated as follows: — Periodical Literature. 489 Regular receipts, $36,660,000.00 Regular expenses, 16,160,000.00 Net income, $20,500,000.00, or just about $3 per acre ; the expenditures being 44% of the gross in- come. Besides, there is an account of extraordinary expenses and incomes, largely made up of sales and purchases of forest land; the excess of expenditures over receipts, being $1,013,000.00; $700,000 alone are to be spent on adjusting rights of user. Of the receipts, wood sales are predicted to yield 387,176,134 cubic feet (57 cu. ft. per acre) at a value of $34,200,000.00 (about 9 cents per cu. ft.). Special Uses are estimated to bring in $1,740,- 000.00 ; the chase $190,000.00. The income for wood has in the decade increased by 43%, but the expenditure by 66% in steady rises. Among the expenses there are the interesting items of $60,000 for telephones and $310,000 for road building. The personnel for the current year comprises : — I Oberlandforstmeister ; 5 Landforstmeister ; ^^ Oberforst- meister; 88 Regierungs — and Forstrate; 822 Oberforster and Forstmeister ; 5167 Revierforster and Forster (Ranger); 49 Waldwarter (Forest Guards) ; altogether 6165 persons. The annual forestry conferences among 18 groups of higher forest officers, described in Forestry Quarterly, Vol. VI, p. 444- 445 are to be continued and $4,500 are set aside for additional travel costs arising therefrom.

(In the United States 395,- 000,000 acres, 72fo of the total 550,000,000 acres of forest, are privately or corporately owned.) The author favors complete freedom of management (except in protection forests) encouraged by instruction and co-opera- tion on the part of the government. This is already the case in Prussia and Saxony; in southern Germany restrictive laws are still in effect, dating from a time when the value of the forest was small. As means of improving the condition of privately owned forests are cited : — Extension lectures ; advice on the ground by neighbor- ing state foresters, especially at the time of planting and of cut- ting; forming of associations; and the creation of a division of forestry in the agricultural council (Landwirtschaftskammer) as has been done successfully in eight provinces of Prussia and lately also in Baden. In Saxony, prizes are offered for the best managed private forest. The author urges the need of a most careful census of all privately owned forests in Germany in order to get a clearer picture of existing conditions. A. B. R.

This is particularly significant when taken in con- nection with the recent purchase in France of the Forest of Eu belonging to the Duke of Orleans, who was forbidden by the State to make a sale to a private company, on account of the doubt which had been cast on the conservatism of future man- agement. This forest was located in the Districts of Dieppe and Neufchatel. A total of 2,301,258 acres was purchased for a total of $2,100,000 or in round figures at 91 cents per acre. This forest was chiefly hardwood, coppice, high forest and coppice under standards. T. S. W. Jr. Revue des Eaux et Forets, April 15, 1914, pp. 267, 268 and 272.

New instructions for the preparatory Forestry Training training in Bavaria and Wurttemberg wil in be of especial interest to those readers Bavaria of the "Quarterly" and of the "Proceed- and ings" who are familiar with the require- Wiirtteniberg. ments in Prussiaf and Austria* and in our own countries of Canada and America. In Bavaria, after the four year course at the University of Munich and passing of the theoretical examination at the close thereof, the government takes on a certain number of candidates for the administrative service — called Forstpraktikanten — who must serve a 3 years' apprenticeship ; 19 months on National Forests, 17 months in a District Office. The first year is spent on a designated forest where the supervisor introduces the candidate into all the various lines of work granting him opportunity to actually carry on some of the work. Emphasis is laid on instruc- tion in the technical and business procedure. Details to neighbor- ing forests where work of special interest is in progress, are ar- ranged. At the end of the first year, the apprenticeship is continued on another forest, selected, this time, by the applicant himself. The object of this second year is to broaden the training of the first year ; the applicant may be assigned the regular work of an Assessor (equivalent to our Forest Examiner) or of a Ranger. Next comes the office experience where the applicant is de- tailed first of all to the Working Plan Section : from May to Octo- ber in actual field work. Besides assisting in the making of work- ing plans, he must independently prepare the plan for a certain unit — that is, do all the work necessary thereto. He gets his expenses for this work and a stipend of $1.20 a day! The following 11 months (November-September) are spent in learning the District Office procedure. This ends the time of preparation; the final or state examina- *See "The Prussian Forest Service/' Forestry Quarterly, Vol. XI, No. I, pp. 42-50. fSee "A Glimpse of Austrian Forestry," T. S.

This examination is a written one but reference books — such as Lorey, "Handbuch der Forstwissen- schaft" are allowed. Eighteen problems, covering the various phases of forestry, are assigned, three hours allowed for each : a total of 54 hours. The papers are marked independently by three higher officials of the Bavarian Service. The Wiirttemberg instructions provide for three examinations, similar to the Prussian schedule, i ) Preliminary examination in the basic sciences, 2) Referendar-examination at the close of the University course and 3) Assessor-examination after 2^ years of practical apprenticeship.* The number of candidates chosen for the government service from among those who passed the pre- liminary examination may be limited and those not chosen given certificates. Three months of practical experience in the woods must precede the Referendar-examination. The 2^ years of practical apprenticeship are without pay, they are to be spent as the ministry decides. However, two semesters of advanced work at a university may be counted in with this. At the end thereof, comes the final or Assessor examination — a very 'stiflf' one. The time of training in Wiirttemberg amounts therefore to 12 years of school (through the Gymnasium or about the equivalent of our sophomore year) plus 8 semesters of technical study, plus one year of military service, plus 2^ years of apprenticeship : a total of 19I years. In Bavaria it is an even 20 years (with us the 10 years of school, 4 of college and one or two of postgradu- ate work for the Master's degree, makes a total of only 15 or 16 years). A. B. R.

Sponsler and E. C. Luebben. A mechanical model designed to demonstrate the growth of a "clean-cut and planted" forest, under regulation, was built and used as a part of the annual exhibit given jointly by the students of the Engineering Department and of the Forestry Department of the University of Michigan. The incentive for making this model was a desire to impress, at a glance, the idea that a forest can have a crop of timber to harA^est at regular intervals and that all of the different sizes are gradually becoming larger. We wanted to show a series of 10 areas, each with a different age class ranging from 1 to 10; and we wanted the stand on each area to slowly grow taller, while the people were looking on, until the end of its rotation, when it would disappear and a new crop start on the denuded area. We did not intend to show an ideal area arrangement of the age classes of a forest, and the model does not do that; but rather we wanted to visualize a growing forest and convey the idea of crops harvested at regu- lar intervals. At least 10,000 people saw the exhibit and the majority of those who were interested in this model, which in- cidentally formed quite a center of attraction, readily saw the points we wanted it to demonstrate. We mention this to show that the model is worth while and worth more thought. Our first model, the one described and illustrated, is a very crude affair in construction and had to be built in a hurry, so simplicity was a necessity. The single cam idea on a main shaft for raising each compartment, was adopted as the simplest and most easily made, after quite thoroughly considering various arrangements of two cams for each compartment, individual and main shafts, racks and pinions, and sprockets and chains com- bined in many different ways. 511 512 Forestry Quarterly The general construction is shown in the accompanying photo- graphs, and a few of the details which may not be clearly evident are described here for the benefit of anyone wishing to build a similar machine. The model is 7 feet long by 18 inches wide and 40 inches high. Each of its 10 compartments consists of a piston with the "trees" fastened to the rectangular piston-head. This piston-head is 7x17 inches, of 1 inch soft pine and the "trees" are arranged in 7 rows, 10 "trees" in 4 rows and 9 in 3 rows, making 67 "trees" in all for each compartment. The "trees" are centrifuge brushes, 9 inches long over all, the brush part is 3 inches long, 1 inch di- ameter at the bottom and ^ inch diameter at the top. The bristles were stained green with Eastman's transparent photo colors. The ring at the end of the handle was bent at right angles and fastened to the piston-head by two staples. The piston rod is 2 inches square by 12 inches long. The lower end bears directly on the cam. In order to reduce friction here, the bearing parts were smeared with soap and then oiled. The cams are made of % inch hard maple. The a:'nensions are given in the sketch. The shaft \s oi Yz inch gas pipe and has holes drilled at regular intervals to receive the pins which fasten the collars in place. The collars are of J4, inch ha^-d maple 1% inch diameter. Each cam is nailed to its collars in such a position that its straight side is 36 degrees in advance of its neighbor on the left. Thus each compartment is raised one- tenth of its full height, higher than its neighbor on the right. We have demonstrated that the model will work nicely and that it is worth developing into a neater and more finished form, and are now planning a few improvements which are suggested here. The wooden collars are to be replaced with metal and keyed to a solid steel shaft. Instead of a direct crank attach- ment to the shaft, a bicycle sprocket and chain will be used in order to gear down the shaft revolutions, and bring the crank to a more convenient height. The top of the model will be made a few inches wider and instead of 3^ inch stuff, % inch cypress will be used and the holes through which the "trees" appear made \]4, inch instead of 1 inch. Underneath the piston-head a coil spring will be used to reduce the jar when the compartment falls after reaching maturity. The piston-rods will be made round instead of square. Model of a Regulated Forest 513 All of the mechanism is, of course, hidden from view when operating and an attempt will be made to make the "forest" more realistic by dipping the stems of the "trees" into a thick brown paint, and by making a brown forest fioor and a green meadow surrounding the compartments. The principal part of the cost of material is in the brushes, which amounted to about $15.00. The rest of the material cost less than $5.00, and the labor was donated. [It may be of interest to add that many years ago, the well- known Dr. Robert Hartig, of Munich, had constructed a model of a regulated forest with age-class distribution, which, while omitting the moving picture show idea of the above model, was designed true to nature in relative dimensions and number of trees per unit area, in each age class, in which respect the above fails. A duplicate of Hartig's "Waldspiel" was exhibited at the World's Fair by the United States Forestry Division and after- wards found its way back to the Museum of the Department of Agriculture at Washington. — [Editor.] THE CREATION OF AN IDEAL. By James B. Berry. While the correlation of theory and practice in American forest schools is usually very good, it is, one must admit, far from per- fect, since the student is not brought into actual contact with practical problems until after his period of training is over and he is on a salaried basis. In other words, his possibilities, whether great or small, remain dormant during his period of training, and it remains for his employer to bear the expense of his further development, to see whether he possesses the "making" of a forester. Certainly this is unjust to the employer, for he must shoulder the responsibility of the student's training with- out any guarantee that the time and expense will be repaid. As conditions become intensive and competition stronger the dis- crepancies of the present system will become more api,-arent and will, undoubtedly, be righted in the process of economic evolution, which will in all probability be somewhat similar to that wMch has taken place in Germany. The German forestry student must have completed four years of work of University grade before he may come up for the State examination, the successful comple- tion of which entitles him to further training and a position in the Government Service. Up to this time he may or may not have had "field work" — if he is the son of a forest ofificial, his training has been very good indeed ; otherwise the chances are that he has had little training outside of his University or Forest School courses.* That is to say, to the son who expects to follow his father in the profession, come greater opportunities than come to the man whose father is in another profession. Before completing the four-year course of study it is possible for the student to have obtained considerable practical experience, either through inspection of operations on various forests or by secur- ing actual employment in a survey or estimating crew ; although *The writer overlooks that in most German State forest services, the young men entering the forestry career are required to spend one-half to one year on a forest under guidance of the manager, doing practical work and becoming acquainted with the business. — Editor. 514 Creation of an Ideal 515 the latter opportunity is open usually to the sons of forestry of- ficials only — for favoritism exists even under the German system. In addition to this work, occurring during vacation periods, the school year offers many excursions, of from one day to a v^eek's duration, besides some practical training in the use of instru- ments, particularly in connection with the courses in Mensuration and Surveying. The excursion inspection work is very good, al- though it is not possible always to arrange for the inspection work to follow closely the class-room work. As a rule the entire teaching force of the forest school takes part in the excursion, each professor drawing attention to illustrations of his own par- ticular course or courses. Thus, the German forest student, up to the time of taking the State examination, has had a high grade of training in theoretical forestry, very good inspection work of practical operations and sufficient training in the use of instru- ments to make him entirely conversant with their care and opera- tion. It is entirely safe to state that, if the student has had the advantage of "position," at the time of examination he has had a correlation of theory and practice unequalled in America ; yet he is not considered as being fully equipped for his profession. Up to this time his training has been ''memory work" very large- ly ; in the future it is to be of a nature to develop his executive ability — in other words, a preparation to shoulder responsibility. Successful competition in his State examination carries with it the designation "Practicant" (in Bavaria), and he enters on a train- ing period extending over three or four years, varying somewhat in the different States. The first year of this period, during which he receives no salary, the practicant has further opportunity for the formation of ideals. He is, in reality, an advanced student in forestry — a graduate student, if you please. He has been as- signed to some forest where he is directly under the supervision of some forest officer — Supervisor (Oberforster), Forest Assis- tant (Forstassessor), Office Assistant (Adjunkt), Ranger (For- ster). He is "under the supervision" of these men, yet his rela- tion is rather that of a student to his teachers — they do not have the right to place him at manual labor — he is there to be devel- oped and purely manual labor is not a means to this end. Much of his time he is in the forest with some one of these men, asking and answering questions. A sample day with the Supervisor 516 Forestry Qua/rterly might be as follows : The Officer keeps up a rapid-fire series of questions: "What species of tree is that? This? What species is that log ? How do you know it is that species ? What habitat does it prefer? What grade of lumber does it make? What's the matter with this tree? What species is this fruiting body? Is there any method of control? What insect did this work? Which of these trees would you fell in making a "light" cutting under the shelterwood system? How would you fell that tree? Is it sound? What would you estimate the volume of this tree to be? See how the stump analysis compares with your volume table. What quality of site is this? How would you regulate cutting on this slope? How would you secure reproduction of oak? Estimate the material, labor and cost of this stream regu- lation," and so forth. There may be no particular order, yet the questions are pertinent and of a character to bring out the best in a man. The forest officer gives explanations and makes correc- tions and suggestions, stating the results of his experiences. One not accustomed to this work is much surprised at the earnest enthusiasm which is present; the personal relation is invariably good, yet the practicant shows every respect for his b!iperior in rank. Various work is planned and the practicant makes studies of practical forestry problems. In the office he becomes conver- sant with the 'working plan and the system of account-keeping. No one who has not been through such a "graduate" school can appreciate the wonderful correlation of theory and practice which is achieved, nor understand the rapid development in manly quali- ties. It is more like a year of private tutorage, and the practicant's ability to think and plan for himself is developed to a high degree. After the first year, the practicant receives a small salary and is given opportunity for further development. Perhaps he is given charge of some line of experimental work, gathering data for volume tables, or working up some problem in connection with regeneration. Whatever is the character of this work, he carries it to its completion and feels the entire responsibility of the enter- prise. The last year, if his work has been very good, he is placed in charge of a small area of forest over which he has full super- vision. In this way there is a gradual development of ability dur- ing the entire period and the result is a man of high efficiency — a professional man worthy of a good position. If his work has Creation of an Ideal 517 been entirely satisfactory, he is given the promotion standing of Forest Assistant (Forstassessor), although some of the States require a further examination for this promotion. Seldom is the entire period, as practicant, spent on one forest ; usually he goes from forest to forest and from district to district so that he may see the best in each branch of work. In this way his training re- mains broad, and he retains his power to think independently. The countries of Europe have never failed to recognize the value of the German educational system, especially in its appli- cation to forestry, and practically all of the educational Institu- tions now have regulations limiting the number of foreign regis- trations to a certain per cent of the total. Foreign students pursue the same courses as the German, take the State examinations and, usually, spend at least one year as practicant. Most of these men must take a further examination upon their return home, for few of the countries recognize the standard of State examination of the others. A few of the countries require that their students in forestry spend at least a portion of their period of preparation in Germany. England requires aspirants for the Indian Service to spend one year following the university course in practical work in Germany, and, in order that these men experience no financial difficulty, makes them an allowance of $1,500 for the year. Under a special arrangement with the Government these men receive the training of practicants, although they are given greater latitude in the choice of work. Semi-monthly they sub- mit reports, in German, to the Home Office, describing the work performed and giving the data collected. Italy, Greece, Rou- mania all require that their students in forestry spend at least a portion of the time in Germany, although they offer no financial inducements. Occasionally, German governments arrange foreign tours for members of her Forest Service and it is expected that this feature of the work will grow rapidly in the future. There should, in fact, be an exchange of forest officials between the different countries, for such an exchange of ideas would be most helpful to all concerned. Of especial value, however, is an inspection of German forest conditions to representatives of those countries whose forestry is in the embr}'onic stage. It is all very well for students to study methods of managment from books, but there 518 Forestry Quarterly can be no real conception, no ideal, without a visual impression of such a method in operation. Photographs and models may serve upon which to hang theory, but practical forestry demands practical demonstration. Germany is very fortunate in the ex- tent of this demonstration work. Here the systems of management have been localized and, as one travels from one locality to another, he meets with demonstrations of each of the principal systems : clear-cutting, shelterwood, group, selection, advance growth. Many of these systems are already in the second rota- tion and the visual impression becomes an ideal for that particu- lar system. Later on, as one attempts the application of a system of managment, he has a very real image toward which to work — something very dififerent from photograph or a model. In this way, the man who is to become thoroughly efficient goes on gathering ideals so that whatever branch of work he takes up he has a clear and definite idea of what he is trying to achieve. Without this ideal, his work must be largely -'f an experimental nature. The forester will not find all of his ideals in Germany, or even in Europe — many of these, particularly in utilization and trans- portation, he will find in America — yet in Germany he will find the best demonstration of system of management, and this is admittedly the foundation of the science of forestry. With these statements as a basis, there are several suggestions which I would like to make for the consideration of American foresters. 1. Lengthening the period of training for students in forestry, so that the man who has completed his training may be a thor- oughly efficient man in his profession. Perhaps this could be best achieved through the introduction of a practicant period extend- ing over one or two years — placing the graduates of forest schools under the supervision of thoroughly efficient technically trained men and making the period one of practical advanced study. In this connection it should be borne in mind that "practical" does not imply "improvement work," but rather the "practical appli- cation" of the theories of the science of forestry. When the forester becomes a "common laborer" he does not merit the re- spect afforded a "workman." This period of training should not be spent on one forest but the practicant should be given opportu- Creation of an Ideal 519 nity to visit the different forests of the several Districts, thus becoming conversant with the best work along each of the several Hnes of forestry. In this way he fomis his ideals — the prerequi- sites of future efficiency. 2. Arranging for a few practicants, or forest officers of higher grade, to spend a few months in European forests under inten- sive treatment. This wori< could be planned so that ten or a dozen men each year would have the opportunity. Detailed plans as to routes, features of forestry to be studied, character of reports would, of course, be necessary. Perhaps it would be pos- sible for these men to receive the courtesies afforded the English forest students. At any rate the entire work should be planned to build ideals. 3. The bringing about of a closer relation between America and those countries in which the practice of forestry is intensive ; best achieved, perhaps, through an exchange of forestry officials. This would, of necessity, be limited to a few men each year or every other year, and the exchange period would extend over one or two years. These men would be given every opportunity they are offered at home for development and, during this period, they would be able to determine how much of the work could be put into practice on their own State forests. Such an arrange- ment would prevent much of the duplication of work which is going on at the present time — not that the several countries desire to duplicate work, but that they do not know, and often cannot learn, what other countries are doing. In addition, each man would receive a stimulus which would result in a fresh impetus of enthusiasm and greater efficiency. THE SIZE OF STATE FORESTS. By J. S. Illick. Thirteen of the United States own forest land aggregating about 3,250,000 acres. New York ranks first with 1,645,000 acres and Pennsylvania second with 1,000,000 acres and 130 perches. The area of State-owned forest land in these two States comprises three-fourths of the total State-owned forest land in the United States. The first requirement of every kind of soil management is the division of the aggregate area into suitable parts, i. e., into ad- ministrative units and managerial units. This is true in forestry as well as in agriculture, horticulture, and gardening. A systematic organization of a forest, which presuppose;": a subdivision of it, is a prerequisite to orderly procedure. It facilitates the directive, inspective, executive and protective function of the personnel. This article will consider the division of State-owned forest land into administrative units. Special reference will be made to the forests owned by the State of Pennsylvania, because in them organized forest management has been in operation for some time. Pennsylvania owns at the present time 1,000,000 acres of forest land located in 26 counties and purchased at a total cost of $2,277,962.31 or an average of $2.27 per acre. The area owned in the 26 counties varies from 1,176 acres in Wyoming and 3,538 acres in Lackawanna to 126,155 acres in Potter and 126,777 acres in Clinton. The total acreage of State-owned forest land in the last two named counties comprises more than one-fourth of the total owned by the State. The major part of the State-owned forest land is located in the rough or mountainous part of the State, and usually found in rather large contiguous areas. Most of it is located in the northeastern, north-central, central, and south-central part of the State. In order to facilitate the direction and inspection of the various forestal activities, a grouping into districts has been proposed and in part inaugurated. The dis- tricting will be worked out primarily on a geographical basis. A district may simply embrace the forest of a single county or it 520 Size of State Forests 521 may include those of a number of counties. A proposed scheme of districting the State-owned forest land is as follows: District 1. To comprise all State-owned forest land located in the northeastern part of the State. District 2. To comprise all State-owned forest land located in the north-central part of the State. District 3. To comprise all State-owned forest land located in the central part of the State. District -i. To comprise all State-owned forest land located in the southern part of the State. Some have suggested a division of District 2 into two separate districts on account of the large acreage of State-owned forest land in it, and a division of District 3 into an eastern and western part on account of its elongated form and its large acreage. A few, rather small, and isolated areas, such as those located in Dauphin and Westmoreland counties, may not be embraced by the proposed districting. They must be treated independently or included in the most convenient district. Future purchases by the State may modify the proposed districting. Each District will be in charge of a forest officer known as a District Forester. The duties of a District Forester may be limit- ed to the forest land owned by the State, in which case he could oversee 10 to 20 State forests with a total area of 200,000 to 400,000 acres, or they may embrace also other functions, namely, the supervision of all Fire Wardens within the District, as well as the giving of technical advice to private owners and co-operating with the officers of Forest Protective Associations which are be- coming numerous throughout the State. In the latter case he would not be able to oversee nearly so large an area of State- owned land. Each District will usually comprise a number of executive charges formerly known as State Forest Reserves but now known as State Forests. A State Forest then is an area in charge of one executive officer known as a Forester. At the pres- ent time the State-owned forest land of Pennsylvania is divided into 49 State Forests with a technically trained Forester in charge of each one. Each Forester is assisted by 1 to 6 Forest Rangers and usually a permanent labor force. In some in- stances the Forester is assisted by a recent graduate from the Forest Academy who is serving a period of apprenticeship, usually 522 Forestry Quarterly of one or two years' duration, prior to being given charge of a State Forest. A State Forest may be isolated, as the Buchanan State Forest, or it may be a part of a large contiguous area, as the Pine Grove, Caledonia, and Mont Alto State Forests. The last three are collectively known as the South Mountain State Forests. The eight contiguous State Forests which comprise all the State-owned forest land located in the Seven Mountains in the central part of the State are collectively known as the Seven Mountain State Forests. The area in charge of one executive officer varies considerably in size. This is true in the National Forests of the United States, the State Forests of Pennsylvania, and the State Forests in the different States of Germany, where forestry has been practised for almost two centuries. The State Forests of Pennsylvania vary from 4,145 acres (Nittany State Forest) to 60,000 acres ( Sinnamahoning State Forest). 'r:.<"ir average area is about 20,000 acres. A large number of factor: influence the size of a State Forest, i. e., the area placed in charge of a Forester. The following are the most important factors. 1 . Intensity and Kind of Management. The more intensive the management the smaller should be the area under one Forester or in one executive charge. The kind of operations which the annual budget contains and the amount of money allotted for them indicate in part the intensity of manage- ment. State Forests which are very productive and yield high returns should be smaller than those which yield little and are practically unproductive. It is quite evident that a Forester can handle a much larger area under extensive management which consists mainly of informing the public concerning the importance of forestry, protecting the area from organic and inorganic agen- cies, regulating the cutting operations, planting unproductive areas, and waiting watchfully for the economic time and the de- velopment of public sentiment, than he could handle under inten- sive management, which considers in addition to the above enumerated fundamentals also such technical subjects as incre- ment, the determination and regulation of the yield, the subdivi- sion of the forest, age-class and growing stock conditions, etc. The development of a Demonstration Forest is contemplated in Sice of State Forests 523 Dauphin county where the State owns 3,358 acres. This acre- age is small in comparison with the other State Forests, but is of ample size for a forester in view of the intense and detailed activities required in a demonstration forest. Under extensive management as one finds on the National Forests, a Forest Super- visor often has more than 1,000,000 acres under his charge ; under conservative management as one finds in the State Forests of Pennsylvania, a forester has charge of about 20,000 acres on an average, while under intensive management as one finds in the forests of the State of Saxony, Germany, a Forstmeistcr, or Oberforster as he is called when first appointed, has charge of about 4,130 acres on an average. 2. Species, Forest Structure, and Means of Regeneration. Hardwood species are more difficult to handle than coniferous species, and mixed stands more difficult than pure stands. The natural forests of Pennsylvania are mixed, with the hardwoods species far in the majority, hence a forester will not be able to handle as large an area as if they were pure and coniferous in structure. On account of the recent artificial establishment of large areas the forest structure is changing. The transition is gradual and cumulative in favor of the conifers. Natural seed re- generattion is a more extensive method of reproduction than arti- ficial regeneration, hence wherever natural seed regeneration is the prescribed method of reproduction a forester can handle a larger area than where artificial regeneration is in practice. 3. Degree, Kind, and Amount of Utilization. The total amount of material that is utilized annually has an in- fluence upon the size of a forest. The greater the productivity, which manifests itself in the annual or periodic yield, the smaller the area of a forest should be. Under extensive management the total yield consists of the final yield but as the management becomes more intense the intermediate yield becomes more im- portant and may amount to as much as 50 per cent of the total yield. At present the thinnings in the State Forests amount to little, but in the future they will amount to more. If history will repeat itself we may be able to anticipate the growing importance of 524 Forestry Quarterly thinnings by a study of the development of thinnings in the Municipal Forest of Heidelberg, Germany.

Thinnings per Acre {Cubic Feet). 1837-1846 4.2 1847-1850 0. 35 1851-1860 8. 82 1861-1870 6. 86 1871-1880 7. 28 1881-1890 13. 16 1891-1898 24. 36 1898-1900 34. 72 1901-1909 44.94 A forester who is required to make extensive thinnings, clean- ings, damage cutting, cannot handle as large an area as he could if such operations were absent. In regions with a dense popula- tion one finds greater demands for small material, especially fuel- wood, which is absent in sparsely settled regions. The sale of small material and of small lots as well as the filling of special and small orders complicates the work of a forester. The satis- fying of a local market tends to reduce the area of a forest. The degree or extent to which a forester refines his production before he sells them will help determine the area which he can handle properly. He may sell the material upon the stump, or he may fell it and cut it into logs, poles, posts, ties, cords, etc., and then sell it, or he may refine it still further by running it through the sawmill, and then dispose of it. 4. Number of Trained Men Available. During the formative period of any art or business the number of technically trained men able to handle it is usually very small. Forestry was no exception to this. In response to a constant de- mand for trained foresters many forestry schools have sprung up. In 1898 the first forest school in the United States was es- tablished at Biltmore, North Carolina. In the same year a second one was established at Cornell University. To-day 24 forest schools prepare men for the practice of forestry as a profession and 50 more given general or special instruction in forestry. On January 1, 1908, the State of Pennsylvania owned 752,492 acres of forest land. At that time only 10 men, trained especially for the position of forester upon the area, were available with an Sice of State Forests 525 average of more than t."),000 acres per man. Three years later, January 1, 1911, the total acreage had increased to 933,115 acres. By this time 40 foresters were available with an average of 23,328 acres. At the present time the State owns 1,000,000 acres which is in charge of 49 foresters or an average of a little over 20,000 acres per forester. In time the average acreage per forester will be reduced to about 10,000 acres. The training, which the executive managers of forests in America have, varies widely. In Germany it also varies, but less widely, because each State has some prescribed qualifications which a man must be able to meet before he can be promoted, and the prescribed qualifications in the several states approximate each other. The German Oberforster is about 40 years of age when he is appointed to this position. He holds subordinate positions up to that time. It has, however, been recommended that the limit be lowered so a man could attain this position not later than at the age of 36 years. In America only a few executive mana- gers have as yet attained this age. The salaries which these trained executive managers receive bear comparison and are given below : State. A nnual Salary. Wurttemberg $725-$1125 Hesse 700- 1500 Prussia 750- 1800 Saxony 975- 1875 Bavaria 1200- 1800 Pennsylvania 720- 1500 5. Number and Kind of Assistants. The larger the number, and the better the training of the assis- tants to a forester are, other things being equal, the larger the area that he can handle. A forester who has another subordinate forester assisting him, and in addition has a large number of permanent and emergency rangers, a large permanent labor force, and a satisfactory office force and office equipment, certainly can handle a larger area than a forester who has very little and poorly trained assistance. The number and kind of subordinate officers should be determined by the area of the State Forest and the intensity of management. 526 Forestry Quarterly 6. The Time a Forester Necessarily Devotes to Office Work. The ordinary duties of foresters are alike in kind but differ in degree. All have office work and forest work, but the amount of office work some have far exceeds that of others. The apportion- ment of time for forest work and office work helps to determine the area which one forester can handle. The office work of a forester is diversified, consisting of such items as correspondence, reports, bookkeeping, making of working plans, utilization plans, and planting plans, preparing cost reports of prospective operations, advertising and reporting wood sales, etc. A certain amount of office work for a forester is natural, but too much means that his work in the forest is managed poorly or given into the hands of a subordinate, in which case the forester plays simply the role of an inspector, which is very unsatisfactory. In cases of excessive office work a clerk, either permanent or temporary, depending upon the amount of office work, should be supplied. Up-to-date equipment should be found in the office of every forester to facilitate office work. The office work upon some of the State Forests of Pennsylvania is starting to become burdensome. It will become more burden- some as the management becomes more intense. Conditions are not different in Germany. An accurate diary kept by a conscien- tious Forstmeister shows that he spent during the year only 133 days of 9.4 hours each in the forest and 128 days at office work. A forester who must spend one-half of his time in the office cer- tainly cannot manage as large an area as one who spends only one-fourth of his time there. A forester should spend at least 4 whole days per week or their equivalent supervising in person his forest activities. 7. Auxiliary Duties of the Forester. A forester who has no duties aside from those on the State Forest upon or near which he is located, can manage a larger area than if he has many or extensive outside duties. A forester may devote little or much time to informing the public concerning the importance of forestry, to assisting private owners in developing their woodlands, in cooperating with the numerous Fire Pro- tective Associations which have sprung up in recent years. In some forests considerable time may be devoted to the location and supervision of camp sites, while in others little time may be re- Sise of State Forests 527 quired. Five large and eleven small forest-tree nurseries are operated in connection with State Forests in Pennsylvania. The amount of nursery work which a forester must attend to will in- fluence very decidedly the amount of forest land which he can handle in connection with the nursery. The number and kind of his assistants is a very potent factor. One forester, without trained assistance, cannot manage a nursery with an annual yield of one million seedlings and at the same time handle properly a State Forest of 25,000 acres. The area under the charge of a forester should have such a size that his entire time will be com- pletely used up without being overburdened either by ofifice duties or by technical forestal activities. In addition to his official duties he must have time for personal development as well as scientific and managerial investigations. Last, but by no means least, he needs some time for his family. His isolated location brings many family tasks to him which men with homes in more popu- lous regions are not required to fulfill. 8. The Situation, Form and Coherence of the Forest. A certain amount of State-owned forest land may be so sit- uated with regard to other State-owned forest land that it will become necessary to include the former in a State Forest even though its acreage may be somewhat excessive or somewhat be- low that which a forester could carefully and conveniently handle. For example the Stuart State Forest, named after ex-Governor Stuart, contains only 8,749 acres. It is located in eastern West- moreland and western Somerset counties. It is so distant from other State-owned forest land that the acreage cannot be in- creased. Contemplated purchases may increase the acreage. Hence its isolated situation primarily determines the area of this State Forest. The form of the area also influences the total acreage which a single executive officer can handle. If the area is in a compact block approaching a square or regular in outline one can handle a larger area, other things being equal, than if the area is decided- ly elongated and very irregular in outline. The Poe State Forest is on an average two miles wide and 14 miles long. The distance around this area is about 45 miles, while it contains only 14,000 acres. The same area could be in a block with a perimeter of less 528 Forestry Quarterly than 30 miles. If such were the case, it undoubtedly could be managed more easily. Coherence is also a factor which influences the size of an executive charge or State Forest. If the total area is in one compact mass, the area allotted to one forester can be larger than if his forest consists of scattered patches, blocks, and ranges. The Buchanan State Forest, named after ex-President Buchanan, consists of two parts separated by a distance of six miles. The total acreage is 10,973 acres, 6,760 acres in one part and 4,213 acres in the other part. With the same efifort, the forester could manage a larger area if it were in a coherent block. Interior holdings also make management more difificult. In case of scattered tracts too much time is spent on the road. 9. Topographic and Climatic Factors, Location of Forester's Headquarters, and Means of Locomotion and Communica- tion. In a rough and mountainous country one man cannot handle as large an area as in a level or rolling country. In regions with intense and prolonged winters and in regions with heavy and extended rainfall a forester can spend less time at activities in the forest than in regions with less rainfall and with a longer open season. The location of the headquarters is a factor in determining the size of the areas over which a forester can take charge. The most favorable location from the viewpoint of accessibility is usually within the area or at the side of it. In some cases this is impossible and the forester may be compelled to live at a short distance and sometimes at considerable distance from his forest. The means of locomotion is closely interrelated with his headquarters. He may be able to look after his forest better with headquarters on the outside of it than by having them within if he has good means of locomotion in the former case and poor in the latter. Good railroad and trolley service may aid him considerably. Good roads will enable him to drive, or ride on horseback or a motorcycle. A few foresters have automo- biles, which are very helpful to them where good roads are abundant and ramify through the major part of their forest. Telephone communication with subordinate, coordinate and su- perior forest officers will enable a forester to take charge of a Sice of State Forests 529 larger area than the absence of it. The more important State Forests are now well equipped with telephone communication. From the above classification one can see that the number of factors which influence the size of the area under one execu- tive officer are many. It is impossible to classify the factors in order of their importance. Their importance varies with the general environment of the area. In some cases it is the conjoint influence of a number of factors, rather than the influence of a single factor. These factors have their influence under intensive as well as under conservative and extensive management. On account of these numerous factors and their influence under all kinds of management, one can never expect to have State Forests of equal size. We have been and are still learning much from German ex- periences and experimentations in forestry. The executive man- ager of a forest in Germany is known as a Forstmeister or Ober- forster, in the National Forests of the United States as a Forest Supervisor, and in the State Forests of Pennsylvania as a For- ester. The average acreage under the charge of one of these executive managers in several states of Germany is given below : Stale. Area in Acres. Saxony 4,130 Hesse 5,000 Wurttemberg 6,175 Braunschweig 6,250 Oldenburg 8,000 Bavaria 8,250 Baden 9,000 Prussia 11,500 Alsace Lorraine 14,000 The average area under one executive manager or in one executive charge varies from State to State and changes from year to year in the same State. In 1908 it was 7,700 acres in the State of Bavaria, and in 1911 is was increased to 8,250 acres. These average figures for various States are interesting and in- structive, but they do not give one any idea of the variation in size of forests in charge of one executive officer within one 530 Forestry Quarterly and the same State. The subjoined data will show the variation within the State of Wiirttemberg : 1 Executive charge with less than 2,500 acres 7 charges ( 5%) with 2,500- 3,750 " 22 (14%) " 3,750- 5,000 " 50 " {ii%) " 5,000- 6,250 " 43 (29%) " 6,250- 7,000 " 20 (13%) " 7,000- 8,750 " 7 ( 5%) " 8,750-11,250 " 150 Executive charges with- a total area of 925,000 acres or an average of 6,175 acres to each executive charge. From the above outline one can see that there are in Wiirttem- berg 30 executive charges, i. e., one-fifth of the total number, that have less than 5,000 acres, and 80 or over one-half of the total number, that have less than 6,250 acres. These figures are of a comparative value and will act as a guide for those who are concerned with the allotment of areas to forests. In Ger- many a single executive charge may comprise State, Municipal and Communal forests which make the forester's work more difficult. The subjoined data of 10 of the 49 State Forests of Penn- sylvania will show their wide variation in size : State Forest. Area in Acres. Nittany 4,145 McClure 6,093 Stuart 8,749 Buchanan 10,973 Coburn 15,000 Hull 23,290 Caledonia 26,700 Blackwell 29,000 Cross Fork. 59,592 Sinnamahoning 60,000 One cannot help but realize that the factors which influence the size of the area under the charge of one executive officer are operative in all countries. The degree of their importance varies, however, within the same country, the same State, and often the same local region. That the size of State Forests varies at the present time can be seen in the above tabulation of the State Forests of Pennsylvania and that they will ever continue to vary can be inferred from the tabulation given above of the forests of Wiirttemberg, where forestry has been in practice for more Sice of State Forests 531 than a century. We can never hope to have all our State Forests the same size. It is, however, desirable that an attempt should be made to equalize them as far as the results of the equalization prove to be practical. The truism that "history repeats itself" stands out clearly when we see how the development of forestry in Pennsylvania recapitulates the development of forestry in Germany. No doubt we will pass through exactly the same course of development, only at a greater speed, on account of our present economic condition and the many theoretical and practical lessons which we have and can still learn from the experiences of the countries and States of Continental Europe. If we cannot adopt their results, we may at least adapt them, and if we cannot adapt them, they will at least suggest problems to us and indicate the best means of avoiding circuitous methods of procedure in solving them. NOTES ON GERMINATION AND REPRODUCTION OF LONGLEAF PINE IN SOUTHERN MISSISSIPPI. By p. L. Buttrick. In the spring of 1914 the final term of the senior class of the Yale Forest School was held on the holdings of the Great South- ern Lumber Company in Marion County, Mississippi. Marion County adjoins the Louisiana State line on the south and is drained by the Pearl River. The following data were partly collected by the students in assigned work and later tabulated by the writer, who added ob- servations of his own.^ They do not make a complete account of Longleaf pine reproduction, but present some data which may be of some value to others studying the problem. The region lies within the Longleaf pine belt in what is known locally as the pine ridges. The surface of the country is quite undulating and rather more hilly than most of this pine land. The forest is pure Longleaf pine and practically all virgin. The section has been settled for nearly a century, but save for small agricultural clearings the forest has not been disturbed by the ax. Since the first settlement forest fires have been an annual occurrence. Early every spring the woods are burned over, exposing the mineral soil, and, as a result, undergrowth is the exception rather than the rule. While individual fires do little damage to the mature timber, their cumulative efi^ect, by killing the old trees and preventing the growth of others to take their place, will probably be the gradual elimination of the forest. Comparatively few trees under 100 or over 300 years are found. The average age is about 220 years. What little reproduction is found is in scattered groups and is totally insignificant in area compared with the forest as a whole. It is evident that, if con- ditions continue as they are, in another century the forest will ^Acknowledgments are due to the Yale Forest School for permission to use the data, and to Professor H. H. Chapman, of the School, for sug- gestions as to field studv and criticisms of this paper. 532 Germination of Longleaf Pine 533 be reduced to widely scattered groups of trees, and later will disappear entirely. The assigned work for the class consisted in individual studies to determine the following points : 1. Number of seeds deposited from seed trees at different dis- tances from their bases. 2. Per cent of seeds germinating on different types of ground cover- : pine needles, grass, hardwood litter, litter of varying ages and depths. 3. Effect on reproduction of fire and other agencies. The study was made by taking small-sized sample plots (gen- erally one foot square) under various conditions, but on sites unburned that season, and counting the seeds and seedlings on them, and noting the distance from the seed trees. Since but one crop of seedlings was present, there was no danger of includ- ing those of more than one age-class. The year 1913 was a seed year for Longleaf pine in this region. The seed fell during the fall and winter and began to germinate in February.^ By the time this study was made, in late March, the germination period was practically over. The seedlings bore cotyledons fully expanded and the root system was often two or three inches long. During or shortly after germination much of the ground was burned over, destroying most of the seedlings. A few escaped and some showed signs of at least a temporary recovery from the effects of the fire. According to the best evi- dence, seed years in the region occur about every seven years. Seed Dissemination: The greatest distance given for the fall of seed from the base of a seed tree was 150 feet^ (from a tree on the edge of a field). The average maximum distance was 140 feet. Several observations were made to the effect that the radius of seed dissemination seldom exceeded the height of the seed tree. The dominant trees of the stands in the region average about 120 feet high. The amount of seed falling on about sixty plots one foot ^ This percentage is of course smaller than would be obtained from seed tests in a nursery, and should not be compared with them. ^ U. S. Forest Service reports that by early December, most of the seed had germinated, little seedlings of 2 or .3 inches high being found growing in great numbers, and that at that time groups of seedlings were found by the Conservation Commission of Louisiana as far distant as 300 feet from the nearest seed tree. — Ed. 534 Forestry Quarterly square at different distances from the bases of seed trees has been plotted on cross section paper and a curve drawn which curve shows the relation between distance and distribution. From this curve a table was read, which shows that the maximum amount of seed falls between 20 and 30 feet from the base of tree. This table might be of use in connection with other data in fixing the number of trees to be left per acre under some systems of forest management.

The average maximum was about 60%. The average minimum was about 25%. The percentages seldom ran over 65 or under 25%. Classifying the plots according to their ground cover, we get the following germination percentages : On one-year crop of pine needles 50%* On grass 53% On hardwood litter 28% The difference between the results from pine needles and grass are too small to leave room for generalizations. Individual * These figures average 44 instead of 48%, the difference being due to the necessity of excluding certain plots for which no site data were given. Germination of Longlcaf Pine 535 opinions, as expressed by the students, vary as to which affords the better germination site. Both, although different in appear- ance, generally offered much the same conditions for germina- tion, the ground having been burned over immediately before, so that seeds could easily reach the mineral soil. As to hardwood litter, the results seem conclusive ; not only was germination much lower, but it frequently did not occur on well-seeded areas where there was an excess of litter. Plots were taken on pine litter of upwards of four years' accumulation, but not in suffi- cient numbers to afford reliable averages. It was evident, how- ever, that the germination per cent decreased in proportion to the depth of the litter, and seemed to disappear altogether when a litter of four or five years' accumulation was reached. It seems that the chief requisite for germination is that the seed be in contact with the mineral soil. Although occasionally seeds germinate on rotten stumps and logs (but grow only a few weeks), none germinate on litter so deep as to prevent instant contact with the mineral soil. The study shows an average of 2.6 seedlings per square foot for all sites, or 113,256 per acre (counts on 543 square feet). If 25,000 seedlings per acre be regarded as full stocking, such a crop as fell in the fall of 1913 should be ample to provide for reproduction. Judging from statements of the local inhabitants, this was about an average crop for a seed year. Destruction of Seedlings: Since there is actually no new forest growing up, the question immediately arises : What becomes of these seedlings? As has been intimated, fire kills the major portion of them before they are fairly started. Late summer and fall fires account for the loss of many more. Summer drought and the shade of the old trees, light as it is, cause many more to succumb. Under the combined effect of these factors, only an infinitesimal portion of the seedlings survive the first year. To discover the fate of those seedlings which did escape and get beyond the first year, the writer made a study in the next older seedling age class. A sample plot was taken on a site where conditions were such that part of the crop of the seed year of seven years ago had survived. The results from the study of this plot give much information on the stocking. 536 Forestry Quarterly rate of growth, and fire resistance of the seedlings. Following is a copy of the notes taken on this plot : Date: April, 1914:. Size of Plot: One-quarter acre, square. Site: Crest of a lateral ridge between two water courses one- half mile from their sources. About 25 feet above stream bot- tom. Plot represents conditions prevailing for three-quarter mile along summit and upper slopes of ridge. It is in an old turpentine orchard. Soil and Moisture: Soil a sandy loam, locally considered fit for agriculture. Moisture conditions slightly better than average for the section. Seed Trees: None on the plot. Nearest, 100 feet distant. At that distance plot is well surrounded with them. Average height, 80 to 100 feet. Overhead Cover: Four pine saplings, 4 to 20 feet high, about 15 Spanish, Willow and Black Jack Oaks from 3 to 7 feet high, and from 1 to 3 inches in diameter. Ground Cover: Grass 2-3 density, 2 inches high, a little oak brush 1 foot high, but not interfering with the pine seedlings. Many down trunks of old turpentined trees. Seedlings: Age, all, T years; size, range from 1 to 12 inches high; tap root, 1 to 2 feet long. Number, total, 759; under 3 inches, 3S1 ; between 3 and 6 inches, 330 ; over 6 inches, 48. One Shortleaf pine seedling. Fire, etc.: Plot shows evidence of having been burned annually ever since the seedlings started, but unfortunately it is impossible to tell whether it was burned the first year or not. The last fire, about six weeks previous to the making of the study, had killed but two seedlings, although it destroyed the needles on all save a few of those under 6 inches high. Extended to acre terms there would be slightly more than 3,000 seven-^ ear seedlings on this area after it had been burned annually for at least six years. Even this number should be enough to provide for full stocking at maturity if only normal losses occurred. The chief thing which the plot shows, is what may be expected in the way of stocking and growth, in spite of annual fires, when overhead and ground cover conditions are favorable. Figure 1. Seven-year-old Longleaf pine seedlings in the foreground. They have been burned annually for at least six years. Compare with growth of unburned seedlings shown below. Figurh; 2.

Thus everywhere the same trend of height curves furnishes the possibility to make uniform site classifications by the index height — a purely objective classification found in the stand itself inde- pendent of the estimator. Next, it is found that the development of form factors is in all regions the same: One can therefore everywhere determine the volume for the same age and height and same treatment of stands Periodical Literature 631 by using the same form factor. The influence of chmate, to be sure, is expressed in the stand height, and on this height the form factor depends, hence the stands grown slowly in the far North at the same age have a higher form factor, they are more cylindrical, but two stands in different climate which at the same age have the same height, have approximately the same form factor or taper. An investigation into the cross-section area progress reveals the same condition. The whole investigation permits the claim that the same yield table based on height relation may be used in all climatic conditions. A comparison of spruce yield tables has given the same result. Especially for site classification the author believes this procedure of using the index heights will prove most welcome. Etnheitliche Schdlzungstafel fiir Kiefer. Zeitschrift fur Forst- u.

Honlinger explains, in replying to a criti- Practical cism on his book of this title, the difference Forest of his way of calculating from that of the Valuation soil rent theory'-, which lies mainly in the manner of charging expenses; the soil rent theory charging expenses only against soil, and hence coming occasionally to a negative soil rent, while Honlinger distributes expenses against soil and stock. The fundamental formulae of the two theories compare as follows, for forest- soil- and stock value of the ideal management class : Soil rent theorv^ : F = — ; Sr = :; r^ ; St = — -— .op ' \.op''—l' .op l.op"—!

Glaser points out that values are, in Approximating general, always compromises or averages of Soil subjective opinions. The average of these Values opinions may be considered as the average value of the object, or the general basis on which the price is fixed by the exchangers. Hence, to find simple 632 Forestry Quarterly. approximation formulae to be used in figuring values should be the aim of forest finance. The mathematically correct formula for soil rent values is mainly influenced by the chosen interest rate p, which is most uncertain in its determination and which is usually based on some supposition of soil value, which makes the formula to be a chain in a vicious circle. Glaser proposes to obviate the difficulty by asstiming that the interest on the incomes before the year r compensate the interest on the expenditiu-es up to the year r, and hence the approximation can be made Sr= Yr-\-'^Tr — c—ra. This looks like the forest rent, but as soil rent it expresses the rettirn every r years from the area unit, while as forest rent it is the annual income from r units. The assumption of the equality of interest charges is left without basis, but the author considers it as well justified as the other assumptions of the formula, namely, of eternally equal yields, continuously equal rotations and interest rate. Setting this approximate soil value as 5;., the true soil value formula would be Sr = sr.f{r), when/(r) signifies the average values c of — , figures for f = 40 to 120 and the different species and site Sr classes. The author then compares the results of this and other approx- imation formulae with the theoretically "actual soil value" figured \\dth 3% for various species, site classes and rotations, and finds his method furnishing best results. Having ascertained the soil values of site I and setting them as 1, the following fractions were found to approximate satisfactorily values for other sites.

Dr. Wimmenauer looks back upon twenty- More About seven years of teaching at the University Soil Rent of Giessen (in Hesse) and reviews the stand he took on the question of soil rent at the beginning of his teaching activity (March, 1888). At that time he had defined the object of soil rent as a "satisfactory interest rate on all forms of capital entering into forest production." Periodical Literature 633 He added: "The fight about the theory, it is to be hoped, will soon be a thing of the past; its practice in the forest belongs to the future." Unfortunately the fight about the theory is not yet over. Opponents of the soil rent theory are still active as witness the periodical literature on this subject. However, Wimmenauer, after carefiilly reviewing the matter, sees no reason to change the stand he took twenty-seven years ago (in common with Pressler, G. Heyer, Judeich and Martin) that it is the task of forest manage- ment to strive for the highest interest return on the forest capital possible with the species and the silvicultural system. When it is remembered that Dr. Wimmenauer preceded his academic activity with twenty years of practical experience, this result of forty-seven years of well-balanced thinking will not be weighed lightly.

UTILIZATION, MARKET AND TECHNOLOGY Last year a peculiar association was Railroad Ties formed in Germany, the Beech Industries in Germany Association, excluding from it the firms which handle railroad ties, who make imdesirable competition to the other industries, stimulated by increase in prices of the latter. With the reduction in the offerings of oak ties, the use of beech ties is increasing. Yet in the contracts for ties made last fall, for this year's delivery, prices have somewhat decHned. To cover the requirement of the Prussian railways of 840,000 pine ties and 314,000 hardwood ties, over 3,900,000 pine ties and 1,210,000 hardwood ties were offered, but of these only 143,800 foreign oak ties. On pine ties an increase up to 11 cents (price varying much with locality) was experienced, but beech ties, while as a rule from one-half to 10 cents dearer, in some places show slight declines. Prices for pine ties ran as a rule between $1.10 and $1.20 and for foreign ties a little lower; creosoted ties are from 25 to 50 cents 634 Forestry Quarterly higher; oak ties run up to $2.00, while treated beech ties run somewhat lower and up to $1.66 at most. An interesting discussion — made more interesting on account of the war — was published in 1912 by General von Liebert, comparing metal ties and wooden ties from the standpoint of military value. He points out that the requirements of metal ties as regards road-bed, fastenings, and tamping are such as to make them tmdesirable in war time, while the wooden tie fits into any situation and can be fastened to the rail much more simply. He advises, therefore, on the frontiers to use only wooden ties, also because restoration of destroyed tracks would be more easily effected. (Half of Germany's mileage is on metal.) Considering that in 1910 about 5 billion cubic feet of wood for tie purposes had to be imported, it would appear that there is no need from the forestry point of view to advocate the wooden tie.

STATISTICS AND HISTORY The Development and Road Improvement Forestry in Act of 1909 provided for the creation of a United Development Fund and a Development Kingdom Commission, and with the end in view of promoting the economic development of the United Kingdom. The fund now aggregates $14,500,000, and may be applied for agriculture and rural industries, forestry, reclamation and drainage, harbors, inland navigation, fisheries, etc. As defined in the Act, forestry includes the conducting of inquiries, experiments and research for the promoting of forestry and teach- ing methods of afforestation, and the purchase and planting of smtable areas. Money from the Development Fund may either be granted or loaned, and applications for advances are received only from public bodies, not from individuals. The Commissioners have no executive powers, do not make grants or loans, or carry out any schemes, but merely act in an advisory capacity to the Treasury. From this report we find that through the recommendations of the Commissioners the Board was granted $32,500 for 1913-14 for Periodical Literature 635 forestry research, technical advice, etc. Of this, $12,500 went to support advisory officers at Oxford, Cambridge, Cirencester, Bangor and Newcastle. Steps were taken to enable the utilization of the Forest of Dean for a forest demonstration area. An equipment grant of $68,500 provides for a foresters' school, woodmen's school, museum, library, laboratory and arboretum. The maintenance grant for the ensuing year is $8,500, which seems low. It is expected that the Dean Forest will thus develop into a national centre for forestry studies and experiments. The Corporation of the City of Liverpool was recommended for a loan of $125,000 for afforestation purposes. J. H. W. Fourth Report of the Development Commissioners.

"The first annual joint report of the Statistics Forestry Branches of the Board of Agricul- Great Britain ture and the Crown Office of Woods gives, besides a review of the year's work, a brief survey of the attitude of the State towards forestry from early times to the present, an outline of the history and present position of the Crown forests, together with descriptions of the woodman's school and the distillation works on the Forest of Dean. An account is also given of the timber trade of the United Kingdom from the eighteenth century onwards. A map showing the extent of woodlands and uncultivated land in England and Wales accompanies the report." From the report we learn that the total woodland in England and Wales is about 1,884,000 acres, 3.4% of which belongs to the Crown. The annual production for Great Britain is arotmd 20 million cubic feet, or about 4% of the raw material used in the Kingdom. The imports of wood (manufactured and unmanu- factured) into the United Kingdom averaged $160 million annually for the decade 1903-1912. The imports of the principal kinds of unmanufactured timber had risen 23.5% per capita in 1911 over that of 1891. J. H.W Forestry Report for 1912-13.

The Statistics figures are arranged as far as possible in conformity with the 1910 instructions for forest organization in Bavaria.^ Area: The present forest area of Bavaria is 6,473,408 acres, of which 2,300,975 acres are state forests (of which, in turn, 1,981,259 acres are listed as better suited to growing timber crops than for any other piirpose.) Cut: The annual cut per acre in 1912 was 80.51 cubic feet per acre as against 64.49 cubic feet per acre in 1908, a total annual increase of 28,440,642 cubic feet due to the change from the former ultra-conservative policy.^ What this means in increased income may be judged by the fact that in 1908 the annual net in- come per acre was $5.12 per acre and in 1912 $6.49 per acre, an increase of 26.6%. The quantity of material increased 18% in these four years; the gross income 24.5%. Other Uses: From other sources than wood sales the income in- creased 78% in these four years. The income from the chase alone was in 1912 $96,692. This is the highest money retiun from the chase of any state excepting Wurttemberg, as the following comparison shows: Wurttemberg $ . 065 per acre of forest. Bavaria 046 " " " " Prussia 025 " " " " Saxony 025 " " " " Receipts and Expenses: To show the volume of business it is interesting to note that during 1912, the total receipts were $15,510,371, the total expenses were $7,116,610, making a total net income of $8,393,761, or $1,737,502 more than in 1912. Planting: The total cost of planting amoimted to $25.15 per acre restocked; per acre of forest land $.37. Road Building: This cost $.36 per acre of forest land. Forest Fires: Amounted to only one acre out of 24,754. 1 See "Management of Alpine Forests in Bavaria," Forestry Quarterly, Vol. XI, No. 3, pp. 347, 348. 2 See Practice of Working Plans in Bavaria, pp. 147-159, Theory and Prac- tice of Working Plans, John Wiley & Sons, N. Y., 1913. Periodical Literature 637 Wages: Pay for workers in the woods rose from average of $.715 per day in 1908 to $.833 in 1912. In Baden the statistics for 1912 are as follows: — Area: On January 1, 1913, the total forest area was 1,451,315 acres, of which 246,163 acres are state forests (of which, in tiim, 237,160 acres are listed as better suited to growing timber crops than for any other purpose.) Cut: The annual cut per acre in 1912 was 101.82 cubic feet as against 61.35 cubic feet in 1878. The price of each cubic foot sold averaged |.14. Products other than wood netted $.30 per acre. The total net income was $5.64 per acre in 1912. Species: Of the total growing stock on state forests oak equals 5.3%, beech 19.6%, other hardwoods 7.6% and conifers 67.5%. Planting: The following figures show an interesting decrease in the area artificially restocked due to the propaganda for natural regeneration. Years. Area sown Area Planted Total Acres Acres Acres 1878-1890 336 1,685 2,021 1891-1903 257 1,556 1,813 1904-1912 215 1,304 1,519 In 1912 the cost for sowing averaged $7.03 per acre sown; for planting $28.40 per acre planted. Road building: During 1912 $.48 per acre of forest was spent for road construction. A. B. R.

Swiss importations in 1912-13 of non- Swiss Imports manufactured wood products averaged and Exports 240,000 tons against an export of 35,000 tons. The values of these imports and exports were $6,900,000 and $1,260,000 respectively ($28 against $36 per ton) . The imports of 1913 were by over $1,200,000 less than the preceding year; the export on the other hand increased by over $200,000, the situation showing greatly reduced domestic con- 638 Forestry Quarterly sumption, which was met by the public forest administrations by- reducing the cut by 7 million cubic feet.

MISCELLANEOUS Acorns, Acorns, horse chestnuts and beech mast, Horse Chestnuts if not moiildy or fermented, and if given in and small quantities together with other food. Beech Mast may be used with good results as food for as Food stock, but care must be exercised. Large quantities of acorns, without adequate supply of other foods and of water, are liable to cause acorn poisoning, especially in the case of young cattle under three years. Care should also be exercised in feeding these nuts to pregnant sows and dairy cattle. Their food value consists in the digestible carbohydrates they contain; they are therefore suitable to give with green fodder and food rich in protein. Horse chestnuts also contain carbohydrates. They do not appear to have any poisonous effects, but if taken in large quanti- ties, not supplemented by green fodder or watery foods, have a tendency to bring on digestive disturbances, especially stoppage. Oil cakes (protein) , hay, straw are foods to be used in conjunction with horse chestnuts. Beech mast (the kernel only should be used, the husk containing too much crude fibre to be suitable as food) contains albuminoids, and so would be a supplementary food to those poor in protein but rich in carbohydrates. It can be fed to cattle and pigs freely; poultry, especially turkeys, fatten quickly on it. It, however, contains a constituent injurious to horses, and sheep will eat it only under compulsion. All these nuts, acorns, horse chestnuts and beech mast make better food if crushed and ground into meal. One poimd of horse chestnut meal contains starch equal to that found in 1 lb. 1 oz. feeding barley, 1 lb. 4 oz. oats, 1 lb. 8 oz. bran, or 2 lb, 5 oz. meadow hay. Fresh and unprepared nuts have been fed daily in the following quantities; sheep 3^ to 1 lb., or up to 2 lbs. to fattening sheep; dairy cattle 4 to 10 lbs.; working oxen /^ lb.; horses 6 lb. Pigs prefer the meal, and have shown good results from 1/^ lb. daily.

NEWS AND NOTES It is the aim of the Quarterly to pubHsh interesting news as to the activities and whereabouts of men in the profession. It is hoped to do this more fully than heretofore by the appoint- ment of one of the editorial staff to look after this field. To this end all readers having news of interest are requested to write Mr. A. B. Recknagel, Department of Forestry, Cornell University, Ithaca, N. Y. In running this Department it is the intention to do for the whole profession what is now covered by such local publications at the Yale Forest School News, the Field Program and the monthly news letters of certain Districts in the Forest Service. It is to be understood that in a Quarterly only news that can lay over two months may be printed. The President of the Society of American Foresters during the summer sent out a letter to the members inviting them to co- operate in making the Society more effective, suggesting some methods of doing so, and asking for suggestions. Out of a membership of around 250, only 9 replies were received. Mem- bers who read this and feel guilty are asked to re-read the "round robbin" and mend their ways ! Pursuant to the expressed desire of the Society of American Foresters (see page 300 of present volume), the President ap- pointed a Committee of 21 members to revise and standardize the terminology of forestry terms. The membership of the committee comprises ten schoolmen, six members of the U. S. Forest Service, two State Foresters and three Canadians. The members of the committee are : Messrs. H. P. Baker, W. B. Barrows, R. C. Bryant, W. M. Drake, E. H. Frothingham, A. Gaskill, J. M. Cries, A. F. Hawes, C. D. Howe, B. P. Kirkland, Clyde Leavitt, P. S. Lovejoy, W. N. Millar, A. B. Recknagel, S. N. Spring, J. H. White, W. W. White, Ellwood Wilson, K. W. Woodward, T. S. Woolsey, Jr., and A. E. Ziegler, and the President. The committee was subdivided into five sub-committees, each having under advisement the terms referring to certain groups of subjects. Following is the list of the subcommittees : Silvi- 642 News and Notes 643 culture, Silvics, and Forest Description; Organization, Mensu- ration, and Management; Utilization and Protection; Valuation, Administration, and General Terms; Collating Committee. The following letter of instructions was all that was sent to the members of the committee, leaving otherwise each subcom- mittee to devise its own way of procedure. "It is proposed to revise and explain the forest terminology, with a view to securing as far as possible uniformity of usage; selecting the terms in use which are preferable, and establishing a synonomy. "This revision may be based upon Bulletin Gl of the U. S. Forest Service, keeping in mind that this first attempt at a termi- nology is neither exhaustive nor in some respects acceptable. "To make the work of a large committee practicable, it would appear desirable to classify by subjects, each subject or class of subjects to be assigned to a small subcommittee for first con- sideration, its findings to be submitted to a collating committee. The report of this committee is then to be submitted to the whole committee, and the final findings, with appropriate argu- mentation, to be printed for discussion by the profession at large before final acceptance. "First, attention should be paid to those terms the use of which is doubtful or not uniform and to those lacking in term value, leaving out of consideration those which appear generally accepted. "The first duty of each subcommittee should be to assemble the terms in use referring to its particular subject or subjects, and report same to collating committee without fear of overlapping, the collating committee acting as reviser. "The Committee is to consist of 19 members from the Society, with three assessors from the Canadian Society of Forest En- gineers, thereby giving the decisions an international character. "It is expected that the chairmen of the subcommittees will do the work, securing from the other members of each subcommittee their criticisms." The work of the committees can naturally proceed only slowly, and so far only progress reports can be made. The following statements have been made by the chairmen. Subsection on Silviculture, Silvics and Forest Description: "The members of this subsection met in May at Ithaca at the time of the opening of the Forestry Building. It was decided to take the terms in Bulletin 61 of the Forest Service relating to the subjects assigned and modify, reject or add to these. Each member was 644 Forestry Quarterly to prepare a separate list. Such list of terms and definitions have been prepared by four of the five members. Compilation and review of these, together with a study of their present usage in forestry literature, has been delayed but is now under way. The compiled results will shortly be resubmitted to the members of the sub-section and to others for criticism and suggestion." Subsection on Organization, Mensuration and Management: "This committee was organized for work on April 16, under the following plan of campaign : Based on Bulletin 61 and other avail- able sources, a list of the terms in use referring to our par- ticular subjects was compiled by the chairman and submitted to each one of the subcommittee for criticisms and suggestions. These criticisms and suggestions were compiled and sent to each member of the subcommittee for a final vote ; terms favored by the majority of the subcommittee to be referred to the collating committee for further action. "In accordance with this plan the nomenclature for Forest Organization was sent out to the members of the subcommittee under date of 29 May, criticisms and suggestions being asked for by June 15. Owing to inevitable delays all the critcisms and suggestions were not received and sent out to all the members of the subcommittee for final vote until August 21. As yet only two members of the subcommittee have responded with their decisions on the Organization terminology ; however, the others should be received before long. "Upon the suggestion of Mr. T. S. Woolsey, Jr., the draft of May 29, together with the compiled criticisms of August 21, were sent to the Forester on August 21. Under date of Septem- ber 24, the acting chief of forest investigations writes, 'Your terminology for Forest Organizaion is now being gone over by various members of the Washington office. As you know, it takes some time to secure comments on anything of this sort from a number of difiFerent men, and I am afraid that it will be hardly possible to return the material to you by October 1. I hope, however, that the suggestions may be secured and compiled so as to reach you not later than October 15.' "The same plan was followed in the terminology for Forest Alensuration. The first draft was sent out to members of the subcommittee under date of July 23, and replies were asked by News and Notes 645 August 15. Up to the present all but one member of the sub- committee have replied with criticisms and corrections. Reply from this member should be received shortly, whereupon the compiled comments will be issued to the entire subcommittee for a vote. "Owing to the geographical position of the members of this subcommittee, everything has had to be done by correspondence, which, of course, involved delay. It has also been difficult to get action during the field season. The tentative draft of the terminology for Forest Organization includes 73 terms ; the one for Forest Mensuration comprises 76 terms." One of the University members of this committee reports: "Since receipt of draft with committee comments, our faculty has held five two-hour (-f-) sessions, bringing out a tentative defi- nition of 19 terms only — about an hour per term for the five of us. We found that we did not know very much about our own usages, that we differed among ourselves as to exact mean- ing and practice, that it was necessary to re-define terms we had thought finally done with, etc." Then, after elaborating on the difficulties and the necessity of much work to come to any conclusions, he continues: ''Our faculty has found the work so interesting and profitable that we propose to go on through the lists as rapidly as practicable — for our own benefits alone." Sub-section on Valuation, Administration and General Terms: "It will be at once evident that the Valuation terms, or better the Forest Finance terms are engrossing the bulk of the com- mittee's effort, since the need for concise scientific definition is greatest in finance. Exactly here is one of the weakest spots in English forestry literature, so that this committee's task is not one of the easiest. "This method of procedure is to construct a tentative alpha- betical list of the terms needing definition, erring on the side of too many terms rather than too few. A hasty review of the English literature on the subject is made in doing this and the terms admitting of ambiguous or conflicting use are specially marked. This list is then used as a guide to the detailed work. "The committee endeavored to divide the work alphabetically, and when the chairman has assembled the manuscripts, it is to be submitted entire to each member of the committee for sug- 046 Forestry Quarterly gestion on terms submitted by other members. The final draft is then made for the central collating committee." The subcommittee on Utilization and Protection has divided the field geographically among the three members, the Rocky ^lountains and Pacific Coast being one assignment, the North, East and Lake States being another, and the Appalachian and Southern region a third. Each member of the Committee is to make not only a revision of the logging terms contained in Bulletin Gl, but also to prepare a list covering the terms used in lumber maunfacture. Results are placed on "three by five" library cards, in order that they may be readily classified. One member has already defined some 250 terms, and hopes to greatly increase these during the next month. "I have found it somewhat difficult to properly define some of the terms in a brief and concise manner, but I think that we will be able to work that out satisfactorily before long. It has seemed both to Kirkland and myself that it was very desir- able that special stress should be laid on the terms used in manu- facture, since at the present time there is no glossary of such terms available, and personally, I have devoted more attention to this part of the work than I have to the logging terms." The Grand Trunk Pacific Railway has announced that con- tracts have been let and other arrangements made for the in- stallation of crude oil as locomotive fuel on their passenger engines to be operated between Prince Rupert, B. C, and Jasper, Alta., a distance of 718 miles. It is expected that this instal- lation will be complete by next June. The announcement does not cover the use of oil-burners on freight engines, it being under- stood that these will continue to use coal, at least for the present. The entrance of the Grand Trunk Pacific into the list of oil- burning railways will nearly double the oil-burning mileage of Canada, the total of which is 726 miles at the present time, all in British Columbia. This is made up of 477 miles of Canadian Pacific lines, 134 miles of the Esquimalt and Nanaimo, and 115 miles of the Great Northern. A most successful and enjoyable meeting of the Society of North-Eastern Foresters was held from July 18 to 20 in the News and Notes 647 timber holdings and mills of the Berlin Mills Co., in New Hamp- shire, the members and their friends to the number of some 25 being the guests of the Company under the excellent personal guidance of Mr. W. R. Brown. A special feature was a visit to the areas logged under Mr. Cary's advice some ten years ago. Without anybody familiar with the ground and the detail of previous condition and treatment this visit was, however, not as instructive as it might have been. In the selection forest the influence of any operation can be studied only by carefully ascer- tained detail descriptions before and after. This meeting was followed by the meeting of the SDC-iety for the Protection of New Hampshire Forests at Gorham, N. H., which as usually was full of meat. The new taxation laws of Massachusetts, Vermont, and Connecticut were explained and "forestry investments" discussed. The most important feature, however, was an arraignment of the procedures of the commis- sion having in charge the purchase of forest reservations in the White Mountains, for having neglected to acquire virgin timber before logging where scenic beauty and protection require it. Owing to war conditions the Forestry Convention, which had been arranged by the Canadian Forestry Association in Halifax, September 1 to 4, was indefinitely postponed. A bill appropriating $1,000,000 for the purpose of enlarging the Florida National Forest has been introduced in Congress, showing that the idea of federal ownership of forests is accept- able even to the Democratic states. The Kaibab Forest in Northern Arizona is a very heavily wooded region, containing two billion feet of timber, more than half of which is mature and ready for the axe. The government has decided to sell the m,ature timber to the highest bidder, under fixed terms. An investment of large sums of money, possible only where returns can be spread over many years, will be needed. The necessary railroad extending the length of the tract will open the region to tourists and campers, who will find here much beauty; the sawmills will give employment to many and other uses of National Forests will also induce settlement. 648 Forestry Quarterly The Philippine Bureau of Forestry was to make their first shipment of material for exhibition at the Panama-Pacific Inter- national Exposition to be held at San Francisco by October 15. Their building at the Exposition is to be finished entirely in Philippine woods. Species so foreign to Americans will arouse interest. Representatives of the Bureau, competent to give information on all branches of forestry and lumbering, will be in charge, and the hope has been expressed that the result, for the Islands, will be an increased export trade in the commer- cial woods. Primitive and modern logging, by means of moving pictures, will also be a feature of the exhibition. Distribution of seed of native trees has been begun in the Philippine Islands by the Bureau of Forestry. The Bureau of Education is co-operating and the Bureau of Public Works will utilize all trees that can be spared for planting along roads. The species found by experiment to thrive under adverse conditions and at the same time to be valuable for market are : Teak, Molave, Narra, Lumbang, Lanutan and Tuai. Guijo, a Philippine wood, is being investigated by the Forest Service to determine its possible use in decking boats and ships. Hitherto the navy department has used mostly of the domestic woods, Longleaf pine, Sugar maple and beech. This brings to mind the fact that the first known forest reser- vations in this country were made for naval material. Mr. Ngan Han, Chief of the Forestry Division of China, visited the Phihppine Islands for several months for the purpose of studying Bureau methods, investigating both field and office work thoroughly. Mr. Ngan Han is a graduate in forestry from the University of Michigan. Settlers in Western Kansas are cutting and marketing soap weed, or Spanish bayonet {Yucca hacata), to supply the demands of soap manufacturers, the tops and roots being the parts of value. Though its qualities have long been known, the harvesting of soap weed is just now becoming commercially important. Nezvs and Notes 649 This weed has been a nuisance, its nature being to spread over extensive areas and kill off other vegetation. For the sake of range improvement, the government desires to rid the forage areas of all such injurious plants, and so Forest Service officers hope that the commercial demand for soap weed will reach such proportions as to not only take an otherwise useless product but also eradicate it from areas utilized to supply forage to cattle and sheep. From the Indian reservations of New Mexico and Arizona, Juniper is furnished as material for pencil wood. One of the uses for blight-killed chestnut that should not be continued is that of crating stone. Quarry owners have found that this wood leaves an indelible stain on marble or granite. The Powell National Forest, Utah, has passed 10 successive years without a forest fire. Sixty little Lodgepole pine trees to the square foot were counted in Southern Idaho in the spring, from seed sown broad- cast on the snow. The dry summer following, however, killed all plants not sheltered. The barking of Lodgepole pine trees, at various periods before cutting them for use as telephone poles, in order that the effect of the exuded resin as a preservative may be secured, is being tried in the Beaverhead National Forest. Lodgepole pine, when given preservative treatment, compares well with red cedar as a pole timber, the latter untreated and outside its own region being dearer than the former. Fire-killed Lodgepole pine showed a strength, under test, equal to 80 per cent of that of live red cedar. The increased price of creosote since 1912 of from 7.35 to 10.04 cents per gallon led to an investigation relative to the compara- tive economy of treating piles. Taking as basis the price of 10 cents per foot for untreated and 30 cents for treated Douglas fir piles, the length of life of untreated piles as eight years, and 650 Forestry Quarterly the investigative result that an increased cost of one cent per gallon raised the cost of treated piles one cent per linear foot, it v^^as found that the treating of piles would be economical up to 22 cents per linear foot, a creosote cost of the same amount per gallon. Port Orford cedar, though sufficiently light, has been found to be too coarse and brittle for the manufacture of artificial limbs. It was tried as a substitute for English willow. The United States Department of Agriculture is to inaugurate a tree distribution system in the Western States. Mr. W. A. Peterson, superintendent of the newly established Field Station at Mandan, N. D., which is to be the distributing center, recently visited the nursery station at Indian Head, Sask., with a view to collecting informaton as to the method of handling the work in Canada. The State Board of Forestry of Indiana appointed two arbor days for this year, one in the spring, the other in October, and requested that the many hands of the people of the State make light the labor of planting 1,000,000 trees. The Forestry Board outlined its share of the work by offering to assist people to a knowledge of what species are suited to certain localities, and what care is needful to these trees. A railroad company and two individuals have been fined recently for shipping lumber from an area quarantined on account of the gipsy and brown-tail moths. The existence of this quar- antine, under the Plant Quarantine Act of Agust 20, 1912, was given general publicity throughout the quarantined area by send- ing copies of the order to all transportation companies and to individuals, as well as by extensive newspaper advertising. On November 9, 1914, an Order-in-Council was promulgated at Ottawa, Canada, viz. : Plant Disease Regulation II, under the Destructive Insect and Pest Act (9-10 Edward VII, Chap. 31), reading : "The importation into Canada of the following species of the News and Notes 651 genus Pinus and their horticultural varieties, viz. : White pine (Pinus Strohus L.) ; Western White pine {Pinus monticola Dougl.) ; Sugar pine (Pinus cembra L,.), and all other five-leaved species of the genus Pinus is prohibited." In the last issue of Forestry Quarterly reference was made to the use of wireless telegraphy for the purpose of speedy trans- mission of news of forest fires. Our statement that practical application of this science was first put in use for this purpose, and that but recently, by the Dominion Forestry Branch has been corrected by the information that wireless telegraphy has been a regular part of the forest protection service of British Columbia for the past three seasons, the Dominion wireless stations on the coast weekly reporting fires visible from the stations, and, also, when conditions are especially dangerous, giving the location, weather, direction and velocity of wind, enabling guards to reach the danger zone possibly in time to check incipient fires. The St. Maurice Forest Protective Association of Quebec patrolled last year somewhat over 11,000 square miles, a little over 16 per cent of the provincial lands under license, with only 11 men. Of the 306 fires, 115 were started by settlers, 17 by river drivers, 8 by sportsmen and 17 by railways. The Govern- ment contributes $1 per day per man. There were 8 lookout stations and 15 miles of telephone wire constructed and 200 miles trail cut. The patrols traveled 60,800 miles, the total expendi- tures were $23,000. It is calculated that fire losses had been kept down to 1-1,00 of 1 per cent of the timber values involved. As a result of the work done by the St. Maurice Forest Pro- tective Association, there has been incorporated this year another association under the name of the Lower Ottawa Forest Pro- tective Association, for the purpose of protecting against forest fires the districts in which are the Nation, Lievre, Rouge and Gatineau Rivers. The area of timber limits protected by this Association has grown during the summer from about 9,000 square miles to 11,812 or 7,500,000 acres. Forty-nine rangers under a manager and four inspectors are permanently employed and these in turn employ temporary help when needed. Forty convictions of settlers for starting fires without a permit have 652 Forestry Quarterly been secured, and it is expected this class of timber fires will be more rare from now on. The provincial revenue for Quebec from forests last year was $1,760,466, with an expenditure of $327,383, $90,000 for forest service and inspecting, only $18,000 for fire protection, and $5,000 for forestry education. The Laurentide Company, having completed, under the forestry division, a survey of its limits of 2,350 square miles of land, mostly timbered, and a map, showing drainage, roads, portages and trails, lookout stations, telephone lines and timber condi- tions, proposes now to enlarge its forest nurseries as a provision for replanting large areas of non-agricultural and cut-over lands. Another step toward forest management ! This progressive company is also experimenting with reindeer to take the place of dogs. The timber revenue of the Dominion amounted to only $434,- 196, the result of the cut of 375,000 M feet and some 500,000 railroad ties, lumber sale prices ranging from $13.80 to $18.30 at various mills. There are 7,371 square miles under license and 970 square miles under permit. The sales of lumber in the West ern Prairie Provinces are reported as 1,434,000,000 feet B. M., but it appears that only about 25% comes from home sources, the bulk coming from British Columbia, and nearly 20% from the United States. The crown timberlands of New Brunswick in 1913 furnished 270 million feet B. M., yielding stumpage dues of around $300,- 000. About 65% was spruce and pine; fir somewhat over 20%, cedar and hemlock about 10% and hardwoods a little over 1%. Other products added some $14,000 to the revenue. Douglas fir makes up 68% of the cut of British Columbia, and the cut has increased 38% during the last two years, all other kinds showing decreases. Poplar (Aspen) is coming more and more into use. Latest News and Notes 653 statistics show that 5,000 cords are used in Canada for the manufacture of excelsior, employed largely in packing furniture. Dominion government forest reserves and parks in the Western provinces total 28,027,424 acres. Two prizes of $100 each are offered for two photographs of the largest tree of a nut-bearing variety in the United States — chestnut, oak, walnut, butternut, pecan, etc. — and of the largest broadleaf tree which does not bear edible seeds — elm, maple, tulip, poplar, etc. Photos of cone-bearing trees will not be included. These prizes are offered by two members of the American Genetic Association, Messrs. Charles Deering, of Chicago, and W. A. Wadsworth, of Genesco, N. Y. The contest closes July 1, 1915. It is hoped in this way to find out in what situations and under what conditions trees attain their best growth, and later, perhaps, to secure seeds, cuttings, grafting wood, etc., from the regions where such trees thrive, for purposes of propagation in less favored districts. The University of Montana has now a Forest School, a new department opened this session, with Dr. Dorr Skeels, an expert logging engineer of the Forest Service, as Dean. Missoula, in which city both the University and the Federal Forest Service are located, is the center of an important forest region and of a rapidly growing section of the country. Mr. W. X. Millar, for the past two years with the Dominion Forestry Branch as Inspector of Forest Reserves in Alberta, has been appointed to an assistant professorship in the Faculty of Forestry, University of Toronto. Previous to his leaving the United States Forest Service, to take charge of the work in Alberta, Mr. Millar was in charge of the Kaniksu National Forest. Professor James B. Berry, formerly of Pennsylvania State College, is in charge of the newly established Forest School, of the State College of Agriculture at the University of Georgia, 654 Forestry Quarterly at Athens. This forest school is the only one in the Southern states offering a four-year course leading to the degree of Bache- lor of Science. Mr. James B. Berry, who has spent some time in Germany, wrote interestingly this summer, under date of July 1st, as follows : "I have just completed my first year in Germany and am very well satisfied with the results. I must confess that the University courses are not markedly stronger than ours at home ; yet because of the "post-graduate" work, the correlation of theory and prac- tice is better. I have been able to visit many of the forests of Germany, and everywhere I have found much that is interesting. The localization of theories, which has taken place in the past, makes each locality a new study. . . . "Forstmeister Meister of the Sihlwald, Zurich, is just complet- ing 40 years of service on one forest and is to be retired this fall. I think his forest is in better condition than any I have visited thus far. "While in Zurich I met Dr. Engler and his staff of assistants. My inquiries as to the card index of international forestry de- veloped the fact that the man who inaugurated the idea had left Zurich, and that the present force had not had an opportunity to take it up. I think the real difficulty lies in the fact that no one had any conception of the enormity of the task, and that it was not until after the collection of data had really started that any idea was had of the amount of work necessary to carry it to a successful completion. One of the assistants told me that the work might be taken up again at almost any time, provided suffi- cient support were forthcoming." On September 13, Dr. Wm. Saunders died at London, Ont., ending a most useful life in his eightieth year. The older generation of foresters and forest reformers remem- ber him as one of the early pioneers, not only in making propa- danga but instituting practical measures in the direction of for- estry work. In 1882, he was one of the three commissioners sent by the Canadian Government to the Forestry Congress at Cincinnati, who invited the Congress to meet in Montreal that same year. Neivs and Notes 655 As organizer and director for more than 25 years of the re- markable string of agricuhural experiment stations of Canada, as early as 1886 he planted demonstration areas to test the be- havior of different species and in different spacings under forest conditions at the Central Experiment Farm at Ottawa and at all stations. It was he who inaugurated the growing and distribution of plant material in the prairie section, which now under the Forestry Branch has reached such large dimensions. One of the most interesting and, for a northern climate, most complete arboreta owes him its conception and close personal attention. In the remarkably sane development of the agricultural experi- mental work of Canada Dr. Saunders, with rare versatility, kept his hand on every detail, and unquestionably was in all matters of agriculture the best informed man of Canada, and that not in an amateurish but more or less specialist manner. With all the characteristics of efficiency, he combined a kindly and gentle disposition, which made him friends wherever he appeared. We need not recite the ephemeral honors by which the con- temporaneous generation tried to distinguish him — his work will live forever, and be his greatest distinction ! Dr. Bernard Borggreve, known by his literary activity and especially by his selection method of thinning, even to American foresters, died in his seventy-eigth year in April of this year. He was retired as Oberforstmeister. For many years he was director of the forest academy at Miinden, a highly suggestive teacher, but pugnacious to the extreme in literary warfare. Mr. R. H. Campbell, the Director of the Forestry Branch of the Dominion of Canada, who attended the diamond jubilee con- ference of the Royal Scottish Arboricultural Society at Edin- burgh in July last, was made a Colonial Honorary Member of that body. COMMENT. The great war, as everybody by this time must have realized, extends its bHghting influences to the remotest corners of the earth and into the smallest concern of the single individual, of combatant and neutral nations alike. Even the Forestry Quar- terly is no exception, for an important part of its raw material, the European forestry literature, is to a large extent, cut ofT. The German and Austrian magazines have ceased to arrive since August, and the probability is that they have ceased to be issued. We still receive, albeit belated, Swiss and Scandinavian publi- cations, but the French have been discontinued or have at least not reached us. That most serious consequences must appear in time may be inferred from the contemplation that in this war from 12 to 15 million men are withdrawn from useful productive occupations — and that the most efficient portion of population — while the less efficient portion has to feed these millions ; that daily not less than 30 million dollars are wasted in destruction of materials, leaving out of consideration the destruction of capital values in the war zones; that five billion dollars' worth of trade (Germany's export and import trade) is practically entirely stopped, and that half the world's trade (that of the warring nations) to the extent of some 25 billion, is jeopardized ; and the neutral nations see their trade injured proportionately. At this juncture we are naturally inclined to speculate as to what the influence of the war on forest administrations may be. In our neutral nation, the financial depression which is in part here, in part still to be accentuated, will bring naturally in its train industrial depression, discourage enterprise, reduce not only exports, but home consumption, and hence curtail logging and mill operations. Such setback may also be inimical to forestry work, wherever such had been begun by private forest owners, for retrenchment is the word, and this can be most easily applied by pruning off^ unnecessary innovations. The same feeling of the necessity of retrenchment may also be reflected in the public services. At least expansion is not likely to be permitted; the forestry movement will be at a standstill while more urgent 656 Comment 657 interests demand attention. In Canada, the same conditions prevail and in addition the call for men and for public expendi- tures for the war, as well as reduction in industrial enterprise, will also at least prevent extension of forestry work, if not cur- tailment. In the European, especially the warring nations, the questions of personnel and labor supplies are probably of greater impor- tance than the market question in the practical field of forest ad- ministration, although the problem of securing forest supplies may also influence the latter, and that sometimes in unexpected places. The first definite views of this latter influence comes from Switzerland. Strangely enough it is the supply of fuelwood that is mainly deranged and in its turn is deranging silvicultural operations, as we think possibly in part favorably. The usual import of 80,000 cords, which figure in the total wood import of some 35 million dollars, as well as the supply of coal is in difii- culty. The federal government advises, therefore, the cantonal governments to take measures to meet the difficulty. The result will be a considerable increase in thinning practice besides in- crease of fellings in fuel forests. Great Britain, which relies practically for all its forest supplies to the extent of around 160 million dollars on importations, has her imports to some extent curtailed, and in some respects has already suffered lack. The Forestry Association points out that mine props and similar material could be supplied from native woodlands but for the excessive railroad freight charges which forbid traffic except by water. A petition to the Royal Railway Commission to se- cure the reduction of freight rates is supported by the Royal English Arboricutural Society and the English Forestry Asso- ciation. The grievances have been aired for many years, but the war conditions have revived the agitation. As regards importations, France can probably secure as much as its wood industries may at this stage of reduced activity need. Most of the French forest area is in coppice (75%), which can readily be neglected for years without much damage. The government forest area is relatively small (3 million acres), and will probably suffer little. But in Belgium and northeastern France, the scenes of the greatest devastation in modern times, forest areas have naturally 658 Forestry Quarterly suffered severe damage and sometimes utter destruction, and in the occupied country all forest administration has, of course, prac- tically ceased to exist. It will take many years to recover the lost ground. From all reports, it is evident that the forests in the war zone have played no subordinate role in the warfare, being used for cover of movements, for barricades and breastworks, and, on the other hand, having been razed to prevent such use by the other party. Artillery tire has destroyed or devastated many an old stand, and common fire many a coppice growth or young age-class. Recovery, as in all forestry work, will be slow — slower than that of the ruined towns and cities. In the end, the worst hit, as in every other respect, will be Germany. While this country comes next to Great Britain in the size of its wood imports with 150 million dollars, it exports manufactured wood materials to the extent of 35 or 40 millions of dollars, so that we may assume that the wood industries re- duced in their activity to strictly home needs can probably be supplied by the home product, with such additions as can be secured from Sweden and Austria. But the fine machinery of forest administrations will probably be very considerably damaged through the disturbance of its administrative personnel and woods labor. When we hear that Oberforstmeister Fricke, Director of the Forest Academy of ]\Iiinden, fell in battle, we can assume that the majority of administrative officers will have taken the field. Indeed, such is the conception of duty to defend the fatherland that probably the whole service is dismantled and left in the hands of those Oberforster and Forster whose age prevents their joining the army. The universities are closed, and there is little doubt, the forest schools are in the same con- dition. In Germany, different from France, the Forest Service is not directly related to the military organization, except that aspirants for the lower service fulfil their regular military duties in special battalions — Jaegerbattalione, where they receive instruction in forestry matters and are developed as sharpshooters. In the higher service there is only a group limited to 75 officers who, while pursuing their regular forestry education are under military organization as despatch bearers, an institution dating from the time of Frederick the Great — the reitende Feldjdger Korps. Comment 659 Woodchoppers are probably also scarce, and felling budgets will probably fall behind as well as planting operations if the war lasts beyond spring. If the Germans succeed in keeping their enemies out of the country, the efifect of the disturbance of regular administration will be negligible, but if the country has to suffer an invasion, especially on the Russian frontier, where extensive areas of coniferous forest are located, the loss by fire will undoubtedly be heavy, and it will require a long time to bring back the equilib- rium of age classes, which it has taken a century to establish. The same causes of forest destruction which have been active in France and Belgium may repeat themselves on German soil. Of course, all scientific and experimental work is for the time abandoned, and after the war for some time there will be, no doubt, curtailment necessary in this direction for financial reasons. The question may be raised whether financial difficulties after the war may not influence the forest policy of the German states, should Germany lose and be mulcted by her enemies. In our opinion, there is no danger in that direction, the management under sustained yield in the state forests has proven too well as the best financial policy to be easily abandoned. The time for sale of state forest property as a financial need is passed. After the war of liberation 100 years ago, it was Hartig's merit that he prevented the sale of state forests ; they were mortgaged instead, and it is only within a few years that the mortgage on the Prussian forests had been entirely paid off. At that time the forests were not one-tenth as valuable a property to loan on as now when their regular income could be capitalized at 600 million dollars for the Prussian forests, and for that of the whole of German forests at two billion dollars. The communal forests will not either be allowed to be disturbed in their administration more than necessary. In Austria, conditions are more variable than in Germany, the far eastern forest areas being still exploited, and there as well as in the western part of the bulk of the properties is in private hands. Financial necessity is much more likely here to disturb the man- agement for sustained yield, or urge less conservative exploitation. Whatever happens, whoever the victor, such a dislocation of financial and industrial activity as this world war necessarily brings about can only be detrimental to all peaceful enterprises, such as forestry. Engineering Instruments owe their success to the policy of the makers for 69 years to furnish only instruments of best quaUty at reasonable prices. They are designed and made to fill the practical require- ments of the man in the field. Illustrated Catalogue on Request W. & L. E. GURLEY, TROY, N. Y.
