It is a part of the Department of the Interior, and has offices in the National Museum. It has a director, a chief clerk, an executive officer, surveyors, and other employees. It is charged with the examination and classification of the mineral lands belonging to the United States, and performs an important work. Within a few years the Survey has made extensive examinations of the regions in the Western States and Territories which produce the precious metals, and also 0f those regions which contain valuable fields of anthracite and bituminous coal and iron ore, and the reports and maps issued have been of great service not only to the government, but to all persons interested in mineral lands. Be-fore long the entire Rocky Mountain region will be carefully examined and accurately reported upon, and the vast mineral wealth of this as yet but partially explored country thoroughly revealed. The Survey has in course of preparation a geological map of the United States which is intended to be very complete. The country will be divided into seven districts, and the geological features of each district will be fully portrayed. The map will be published in atlas sheets, each being composed of one degree of longitude by one of latitude in area, bounded by parallels and meridians.
THE office of the Commissioner of Railroads is attached to the Department of the Interior. It occupies a building on G Street, opposite the Patent Office. All the railroad companies to which the government has granted any loan or credit are required to report to this office their earnings and expenses, and general financial condition, and at certain times officials are detailed to examine the property and accounts of the subsidized roads. These roads are the Central Pacific, the Western Pacific, the Union Pacific, the Kansas Pacific, the Central Branch of the Union Pacific, and the Sioux City and Pacific. The amount of their indebtedness to the government, principal and interest, is over one hundred million dollars. The Commissioner of Railroads is required to enforce the laws relating to the railroads, and to give assistance in various ways to the government directors of the roads.
