The General Land-Office was established as a branch of the Treasury Department by act of Congress, approved April 25, 1812, which authorized the appointment of a Commissioner, at a salary of $3,000 per annum, and the employment of a Chief Clerk, and such other clerks as might be necessary to perform the work, at an annual compensation not to exceed, in the whole, $7,000.

By the act of July 4, 1836, the office was reorganized and the force increased. The number of clerks now employed is one hundred and fifty-four; and even this force is not sufficient to meet the requirements of a constantly growing business. Upon the creation of the Interior Department, in 1849, the Land-Office was placed under its jurisdiction.

The Commissioner of the General Land-Office is charged with the duty of supervising the surveys of private land claims, and also the survey and sale of the public lands of the United States. At present this supervision extends to seventeen surveying districts and ninety-two local land-offices.
