Until very recent years definite knowledge of the amounts and condition of our timber resources and the demands upon them has been so limited that a reliable estimate of our timber requirements and supplies at any future period has been impossible. It is now common knowledge that the present forests of the United States contain an estimated total of 481,800 million cubic feet of standing timber; that the annual drain of 25,000 million cubic feet is partially offset by a growth of 6,039 million cubic feet; and that the virgin forests will carry us another twenty-five years, after which we shall probably be wholly dependent upon growth from cut-over lands. By utilizing the entire 470 million acres of forest land, at prevailing rates of growth these cut-over lands can supply us with an estimated annual yield of 14,000 million cubic feet - a little more than half our present requirements.
