Abstract One third of the total area of the United States, or 614,000,000 acres, is useful only for forest purposes, with the likelihood of an additional area of 80,000,000 acres being added for reforestation by 1950 because of the abandonment of worn-out farmland. Forestry is being practiced on 12,000,000 acres of the private commercial forest land, and on 93,000,000 acres of that owned by the public! Soil changes made in the process of exploiting wild lands are almost wholly in the direction of deterioration. More effort must be devoted to creating rather than merely harvesting crops of timber, forage and water.
