Excerpt from book: n PRESENT CONDITION OF THE FORESTS No proof should be demanded to show that the products of the forests are absolutely essential to modern civilization. Neither should it be questioned that a civilized people must have such products in abundance in order to strengthen and maintain that civilization. That the supply should be ample in quantity and acceptable in quality and character is undeniable; and, furthermore, it needs little proof to demonstrate that the presence of forests assures an equable flow of springs and streams, and that in the absence of that equable flow there are destructive floods followed by dry stream-beds and disastrous erosion of the soil. Argument to show all this would be superfluous; but there are other features of the forest problem which are not so apparent or so well understood. In former times the lumberman took only that which would make merchantable sawed lumber, and small stuff was allowed to grow; but now, between the lumberman, the tie, pole, pulp, and acid man, practically everything is taken and the ground is cleared of all timber growth that can ever amount to anything. No seed trees are left, and if fire follows, as it usually does, the ground becomes a barren waste. Land once denuded of trees and other vegetable growth is subject to inevitable erosion of the soil, and such erosion destroys not only the hillside and mountain slopes on which it occurs, but fills the water courses, and in time, through the deposition of earth brought from above by the water, may ruin the valleys also.
