Preservation of Forests. - Forests are of great value from their effect upon the climate, making it more equable. They tend to cause abundant and needed rainfall and to preserve the moisture when fallen, releasing it to the rivers gradually, and thus preventing abnormal freshets and extreme droughts. By absorbing and parting with heat slowly they cause the changes of temperature to be less sudden than in the open country. They temper the heat, and they serve as a protection, or " windbreak," to adjacent land. Trees, with other vegetation, are essential to the purification of the air. All this is in addition to the obvious uses of supplying fuel and wood for an almost endless variety of purposes, not to speak of the value of trees for shade and as features of the landscape. The reckless rate at which the forests of the United States are being destroyed is becoming a serious matter, not merely because of depriving woodworkers of the materials with which to work, but because of the influence of the forests upon the climate, the soil, etc., upon which so much of the welfare of mankind depends. At the present rate of destruction many generations cannot pass before the supply of wood will be practically exhausted. It is every year becoming more difficult to obtain native lumber of the best quality and large size. One of the most serious aspects of the matter, however, is in regard to the washing away of the soil, which owes not merely its origin but its preservation to the forest and other vegetable growths. Professor Shaler tells us that "it is in this action of the rain upon the bared surface of the ground that we find the principal danger which menaces man in his use of the earth." The individual woodworker may not have control of any forest or wood-lot, but he can at least use his influence indirectly, when opportunity offers, toward needed legislation to restrict, or at least regulate, the improvident waste now going on, and he can in many cases take advantage...
