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. History The GLO oversaw the surveying, platting, and sale of the public lands in the Western United States and administered the Homestead Act and the Preemption Act in disposal of public lands. The frantic pace of public land sales in the 19th century American West led to the idiomatic expression "land-office business", meaning a thriving or high-volume trade. For most of the active period of public land settlement, district land offices were the basic operating units that conducted the business of transferring title. All transactions relative to the disposal of public land within a declared land district were handled through its land office by officials designated as registers, who recorded land applications, and receivers, who accepted payments for land and issued receipts. The position of receiver was abolished, July 1, 1925, and the functions devolved upon the register, whose title was changed to "manager" in 1946. The first of 362 district land offices was opened at Steubenville, Ohio, on July 2, 1800; the last at Newcastle, Wyoming, on March 1, 1920. The peak year for land offices was 1890, with 123 in operation. The subsequent closing of the public domain gradually reduced the number of land offices, until, in 1933, only 25 offices remained. The GLO was placed under the Secretary of the Interior when the Department of the Interior was formed in 1849. Reacting to public concerns about forest conservation, Congress in 1891 authorized the President to withdraw timber lands from disposal. Grover Cleveland then created 17 forest reserves of nearly , which were initially managed by the GLO. In 1905, Congress transferred responsibility for these reserves to the newly created Forest Service, under the Department of Agriculture. Beginning in the early 20th
