An excerpt from the book “Adirondack Timber Cruising”
That a greater appreciation of the forest has developed has been evident since about 1919. In earlier times when lumber and pulpwood were abundant, few thought about the future supply. As forest resources became somewhat exhausted, men began to think in these terms, and to plan perpetual lumbering programs. By using selective cutting methods, better fire protection, better pest control, and a more effective program of reforestation, foresters sought to provide an inexhaustible supply of lumber—a renewable resource adequate to supply the needs of coming generations.
