Part 5 (2/2)

All this forms the basis for the preparation of working plans for the utilization of forests under American economic and silvicultural conditions, not only without injury, but with benefit, to their continued productiveness.

The subjects of forest surveying and working plans are intimately related. Maps are indispensable in the practical work of making a forest working plan. Topographic mapping, timber estimating, forest description, and the location of logging roads, trails, and fire lines, together with Silvics and a knowledge of growth and yield--these and many other subjects enter into the making of a practical working plan to harvest a forest crop and secure a second growth of timber. The student should get all the practice he can in marking timber for cutting under such a plan.

The young Forester must make himself familiar with the administration of the National Forests. He must know how the business of the forest is handled, how it is protected against fire, how the timber is sold, how claims and entries are dealt with under the public land laws, how land in the National Forests is used to make homes, how trespa.s.s is controlled, how the livestock industry on the National Forests is fostered and regulated, and how the extremely valuable watersheds they contain are safeguarded and improved.

THE PRACTICE OF FORESTRY:

The practice of forestry is necessarily different in different kinds of forests and under different economic conditions. All that the Forester knows must here be applied, and applied in workable fas.h.i.+on, not only to the forest, but to the men who use the forest. This is peculiarly true of the practice of forestry in National and State Forests everywhere.

FOREST PRODUCTS:

Under this general subject, the forest student must acquaint himself, through the microscope, with the minute anatomy of the woody stem of coniferous and broadleaf trees, and the occurrence, form, structure, and variability of the elements which make it up. He should become familiar with the methods of cla.s.sifying the economic woods of the United States, both under the microscope and with the una.s.sisted eye, and for this purpose should know something of their color, gloss, grain, density, odor, and resonance both as aids to identification and as to their importance in giving value to the wood; the defects of timber; its moisture content, density, shrinking, checking, warping; and the effect of all these upon its uses.

The chemical composition of wood and of minor forest products, such as tannins and dye stuffs, is important; the properties governing the fuel value and the other values of wood must be studied, as well as the methods of using these properties in the making of charcoal and wood pulp, in wood distillation, the turpentine industry, in tanning and dyeing, and in other industries.

A field of great importance is the relation between the physical structure and the mechanical properties of wood. A student should inform himself concerning the standard methods of testing the properties of structural timber, by bending, compression, shearing, torsion, impact, and the hardness and tension tests, with their relation to heat and moisture, and the methods of seasoning, the use of preservatives, and the effect of the rate of application of the load.

Woods vary as to their durability. It is important, therefore, to know about the causes of decay, the decay-resisting power of various woods, the relation of moisture content to durability, why the seasoning of wood is effective, the theory and the commercial methods of wood preservation, and its relation to the timber supply.

LUMBERING:

Lumbering the Forester should know more than a little about, as how to organize lumber operations, the equipment and management of logging and milling in various forest regions, the manufacture, seasoning, and grading of the rough and finished lumber, cost keeping in a lumber business, methods of sale, market requirements at home and abroad, prices, the relation of the lumber tariff to forestry, lumber a.s.sociations, timber bonds, and insurance. The practical construction of logging equipment, such as aerial tramways, log slides, dams, and flumes, is of peculiar importance, and so are the conditions and changes of the lumber market.

Experience on the land of some operating lumber company is of great value. It should include a study of logging methods, log scaling, waste in logging, the equipment and handling of the mill, the sawing and care of rough and finished lumber, its grading, and so far as possible an acquaintance with wood working plants of various kinds, and with the operations of turpentine orcharding. Studies along these lines may with advantage be almost indefinitely extended to include, for example the utilization of steam machinery for logging, the improvement of streams for driving logs, and other similar questions.

FOREST LAW:

The Forester must have at least a slight acquaintance with forest law, both State and National. It is important to know something of the general principles of cla.s.sifying the public lands, of State laws for fire protection, the development of forest policies in the various States as legally expressed, and the important laws which govern the creation and management of State forest reserves.

Forest taxation, State and local, which has, when excessive, so much to do with hastening forest destruction, is one of the most important questions which can engage the attention of the Forester.

Under the subject of Federal Forest Law, it is not sufficient for the student to acquaint himself with those laws alone which govern the forests. He must also have some knowledge of the creation of a forest policy out of the public land policy of the United States, some acquaintance with the public land laws. A good working knowledge of the laws and regulations governing the National Forests is indispensable, and the student should at least know where to find the more important court decisions by which they are interpreted.

FOREST HISTORY:

The history of forestry in Europe has a certain importance in throwing light on our own forest history and its probable development, and this is especially true of the history of the administration of Government forest lands and of education in forestry.

The history of forestry in the United States, however, is far more important. The Forester must know the story of the growth and change of National Forest organizations, the Forest Officers and their duties, the cost, size, and effectiveness of the Government Forest Service at different times, the Civil Service regulations under which it is recruited, and other similar matters. It is important likewise for him to become thoroughly saturated with an intimate knowledge of the development of forestry in public opinion in the United States, its extension to the other natural resources through the conservation policy, and the relation of the Forester's point of view thus expressed to the present welfare and future success of the Nation.

It is not always possible for the forest student to become a woodsman before entering his profession, but it is most desirable. A Forester must be able to travel the forest alone by day and by night, he should be a good fisherman and a good hunter (which is far more important than to be a good shot), and deeply interested in both fish and game. The better horseman he is the better Forester he will be, and especially if he can pack and handle pack horses in the woods. So that whether the young Forester begins with a practical knowledge of woodcraft or not, he must not fail to acquire or improve it, for without it he will endanger the whole success of his career.

Some knowledge of first aid to the injured is likely to be of great and sudden value to a man so much of whose life must be spent in the woods, at a distance from medical aid. The time spent in getting information on this subject will be anything but wasted.
