U.S. Geological Survey

In 1879, the office of director of the U.S. Geological Survey was authorized by Congress (20 Stat. L. 394), which made appropriations "for sundry civil expenses of the government." Clarence King, the first director, was nominated on 21 Mar 1879 and started work on 24 May 1879.

The first geological survey financed by Congress was authorized by act of Congress on 28 Jun 1834 (4 Stat.
