This report provides background and discusses the inventory and disposal of public lands and other Federal property. For many years the Federal Government has operated under a statutory policy of retaining public domain lands and has disposed of the proceeds from the sale of surplus property other than by the reduction of the national debt. Under the present system, the Government disposes of some types of land when it is determined to be surplus to Government needs, or, in the case of public lands, when it is determined that the national interest would best be served by the sale or exchange of particular tracts of land.
