Abstract

(1)DR. BOERKER'S book is a popular account of the administration and protection of the national forests of the United States, which now constitute about a third of the timber lands in that country. The original forest area was enormous, being estimated at 850,000,000 acres. Nearly half of this has been cleared away, as the land was needed for farms by settlers; but forest fires, felling for timber, and grazing have shared largely in the destruction. To-day the land under timber trees is about 500,000,000 acres. Private ownership entailed disappearance of the forests, as no steps were ever taken to provide for the growth of a second crop of trees upon the ground. State intervention became necessary, and nothing in the political history of the United States is more creditable than the legislation of late years enforce ing measures to preserve from fire and to manage on scientific principles as much of the primeval woodlands as could be rescued from private ownership. Dr. Boerker sketches the history of this great movement.
