The practice of forestry in the United states is mainly on National forests where all timber is cut under methods ]ilanned with reference to the pre duction of a new crop on the same land. National forest administration aims also at utilisation of the forage crop and protection of the water supplies ot the West. Grazing on the National forests is permitted under regulation to prevent injury to young forest growth, streamflow, and permanence of the forage crop. A moderate fee is charged for the grazing privilege.

The total cut of timber for the year was 554,725,000 feet, of which 123,233,000 feet were cut under free-use privileges. The timber cut under sales brought an average price of 2 dollars per thousand.
