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 trespass 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 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 fashion, 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.
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 classifying the economic woods of the United States, both under the microscope and with the unassisted 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.
