United States General Land Office

The General Land Office (GLO) was an independent agency of the United States government responsible for public domain lands in the United States. It was created in 1812 to take over functions previously conducted by the United States Department of the Treasury. Starting with the enactment of the Land Ordinance of 1785, which created the Public Land Survey System, the Treasury Department had already overseen the survey of the Northwest Territory, including what is now the state of Ohio.

Placed under the Department of the Interior when that department was formed in 1849, it was merged with the United States Grazing Service (established in 1934) to become the Bureau of Land Management on July 16, 1946. Provided by Wikipedia
