The following paper gives the results of the oldest thinning experiment in the Southwest, established 10 years ago. When the C.C.C. and other relief programs made man power available for timher cultural operations on a large scale, thinning plots established by the experiment station furnished the only background for development of methods. Applied to the Southwest, timber stand improvement is a much more appropriate term than thinning, because thinning is only part, and often a small part, of the operation. Yet the old thinning plots are yielding much information applicable to the present stand improvement practice. Lines along which further studies should be made are pointed out. "Crop tree" thinning, touched on in this paper and widely used in C.C.C. operations in the Southwest, is discussed more fully in the next article, by E. M. Hornibrook.
