The 'General Land Office', a former agency of the United States government, was created in
1812 to take over functions previously conducted by the
United States Department of the Treasury relating to the
public domain. It surveyed and sold the
public domain in the West and administered the
Homestead Act and the
Preemption Act. It later became part of the
Department of the Interior. From
1900, it focused on conservation. On
July 16,
1946, it was merged with the
Grazing Service, established in
1934, to become the
Bureau of Land Management, an agency of the Interior Department. An early commissioner was
John McLean, later associate justice of the
United States Supreme Court.
