FIRE—THE GREATEST ENEMY OF OUR FORESTS More than axe or saw, and probably more than insects or disease, fire has been the greatest enemy of our forests. In Pennsylvania there are vast areas that can produce only one sort of crop, and that is a crop of trees. Forest fires, more than any other single agency, prevent the production of these necessary crops. Not all fires are equally destructive. Some hres do great damage; others do relatively little But one thing is certain: every forest fire does some damage. Usually the fire damage is greater than is apparent, for fires do far more than merely kill the trees. In many cases they put an end to practically all forest life within large areas. They may even burn the lifp out ^f +h- lorest soil. Forests, irrespective of their ownership, can- not flourish as long as forest fires burn. We need to plant trees on devastated mountain sides. We need more study plots within our 44 Z o i id 7 CO ^ CQ Z O U. ^ s TWhvV'^ 19 Z o u z o -•v y u { z \ \ i .J Xz- •^ a.
