region as snow vanishes under the warm rays of a spring day. Lumbering even to-day is merely the removal of every vestige of timber that has any sale value. But forestry, which is practiced on the National Forests, removes only the mature trees, leaving the young growth to be cut at some future time. Lumbering has been and is to-day forest destruction; forestry is forest conservation under a system of wise use. Lumbering is followed usually by fire, and often by an entire impoverishment of the region in which it is carried on because it destroys both the mature tree and the young growth; under a system of forestry, cutting is followed by young, green forests which are protected from fire for the benefit of future generations. Such a system leaves the region and the industry in a permanent, good condition. The county under the old system receives no more taxes after its wealth is gone; but each county will receive taxes or money in lieu of taxes every year as long as the National Forests shall endure.
