Many ot the principles set forth, al- though applicable to this portion of the opment, and on account of crowding is likely to assume a long, lanky shape, which is very easily damaged by w ind and snow. It is this state of affairs that the owner should strive to obviate by thinning his trees. Thinning is the cutting out of such tree-growths as interfere with the healthy development, and hence the future value, of the crop. This form of thin- ning is termed the "weeding" out of the unde-. ig. 1.—A Well-Managed Forest; Large Trees Ready for Market; growth Sufficiently Dense to Protect the Soil. Under- country, will have to be slightly modified to suit conditions elsewhere. As the supply of white pine decreases and the stumpage value increases proportionately, the aim of nearly every farmer who owns a woodlot is likely to be the production of the greatest quantity of valuable timber in the shortest possible time. To do this, his first object should be to stock the area with a suf- ficient number of trees to form a complete cover overhead. This is not only beneficial to the soil, but al*o for the proper development of the trees. In the natural woods this state of affairs very often exists. Natural forests are likely to be more valu- able than artificial plantations, for most natur- al forests grow only in such situations as are congenial to the life of trees, the seeds of which will not germinate readily in unfavor- able soil-;. Nature seldom errs in the choice of conditions favorable to tree-growth, a judg- ment in which man is
