MANAGEMENT OF FOREST

Professor R. T. Fisher, of the Division of Forestry, spoke on. "The Management of the Harvard Forest" last evening. In demonstrating the principles of technical forestry, the aim of study at the Forest is a sustained yield of a given amount of timber from a given area. The two problems encountered in effecting this regularity of yield are, first, how to replace trees cut and, second, how to improve the immature stand. Various methods are used to replace cut trees, including the group, strip, and thinning systems of cutting and also artificial planting. Care in lumbering, and thinning out of undesirable stock, such as grey birch and oak are the chief means of preserving and improving the stand.

The students at the school not only make observations of these methods but also do a great deal of topographic work, estimating, and analyzing. The annual yield of the 2000 acres gives them plenty to do during the lumbering season, and the rest of their time is employed in theoretical work at the School.
