E. T. Allen
Protecting Existing Forests and Growing New Ones, from the Standpoint of the Public and That of the Lumberman, with an Outline of Technical Methods
.....
To insure a second crop the lumberman has to lose more or less money when he cuts the first. His methods must be more expensive and he must forego present profits on trees he leaves. If he plants, the outlay is considerable. But let us suppose he is willing to do all this, not because he is a philanthropist but because he wants more trees to run his mill some day.
It is a comparatively simple matter to get his second crop started. American forestry has solved this problem fairly well. It is also easy to calculate in most cases, beginning with the sale value of cut-over land, using safe estimate of the next yield and the time required to mature it, and setting a conservative future stumpage value, that growing timber ought to be a profitable investment. If that were all, we could leave the lumberman alone and count on him to perpetuate our forests because it will pay him to do so.
