"Any fool can destroy trees. They cannot run away; and even if they could they would still be destroyed, chased and hunted down as long as fun or a dollar could be got out of their bark hides, branching horns, or magnificent bole backbones. Few who fell trees plant them; nor would planting avail much toward getting back anything like the noble primeval forests. During a man's life only saplings can be grown, in the place of the old trees, tens of centuries old, that have been destroyed."
"It took more than three thousand years to make some of the trees in these Western woods, trees that are still standing in perfect strength and beauty, waving and singing in the mighty forests of the Sierra. Through all the wonderful, eventful centuries since Christ's time, and long before that, God has cared for these trees saved them from drought, diseases, avalanches, and a thousand straining, leveling tempests and floods, but he cannot save them from fools, only Uncle Sam can do that." (Our National Parks, 1901)
