"It is good and right that we should conserve these mountain heights of the old frontier for the benefit of the American people."
"Our vital task of conservation is to preserve the freedom that our forefathers won in this land."
"In this Park, we shall conserve these trees, the pine, the red-bud, the dogwood, the azalea, the rhododendron, the trout and the thrush for the happiness of the American people."
"We must prepare in a thousand ways."
