ADVERTISEMENT. The publications of the United States Geological Survey are issued in accordance with the statute, approved March 3, 1879, which declares that "The publications of the Geological Survey shall consist of the annual report of operations, geological and economic maps illustrating the resources and classifications of the lands, and reports upon general and economic geology and paleontology. The annual report of operations of the Geological Survey shall accompany the annual report of the Secretary of the Interior. All special memoirs and reports of said Survey shall be issued in uniform quarto series if deemed necessary by the Director, but otherwise in ordinary octavos. Three thousand copies of each shall be published for scientific exchanges and for sale at the price of publication; and all literary and cartographic materials received in exchange shall be the property of the United States and form a part of the library of the organization. And the money resulting from the sale of such publications shall be covered into the Treasury of the United States." ANNUAL REPORTS. From the above it will be seen that only the Annual Reports, which form parts of the reports of the Secretary of the Interior and are printed as executive documents, are available for gratuitous distribution. A number of these are furnished the Survey for its exchange list, but the bulk of them are supplied directly, through the document rooms of Congress, to members of the Senate and House. Except, therefore, in those cases in which an extra number is supplied to this Office by special resolution, application must be made to members of Congress for the Annual Reports, as for all other executive documents. Of these annuals there have been already published: I. First Annual Report to the Hon. Carl Schurz, by Clarence King, 80, Washington, 1880, 79 pp., 1 map.-A preliminary report describing plan of organization and publications. II.

The Monographs of the Survey are printed for the Survey alone, and can be distributed by it only through a fair exchange for books needed in its library, or through the sale of those copies over and above the number needed for such exchange. They are not for gratuitous distribution. So far as already determined upon, the list of these monographs is as follows: I. The Precious Metals, by Clarence King. In preparation. II. Tertiary History of the Grand Cañon District, with atlas, by Capt. C. E. Dutton. Published. I II UNITED STATES GEOLOGICAL SURVEY. III. Geology of the Comstock Lode and Washoe District, with atlas, by George F. Becker. lished. IV. Comstock Mining and Miners, by Eliot Lord. In press. V.

Pub Geology and Mining Industry of Leadville, with atlas, by S. F. Emmons. In preparation. Iron of the United States, by Prof. R. Pumpelly. In preparation. Dinocerata.

The others, to which numbers are not assigned, are in preparation. BULLETINS. The Bulletins of the Survey will contain such papers relating to the general purpose of its work as do not come properly under the heads of ANNUAL REPORTS or MONOGRAPHS. Each of these Bulletins will contain but one paper, and be complete in itself. They will, however, be numbered in a continuous series, and will in time be united into volumes of convenient size. To facilitate this, each Bulletin will have two paginations, one proper to itself and another which belongs to it as part of the volume. Of this series of Bulletins Nos. 1 and 2 are already published, viz: 1. On Hypersthene-Andesite and on Triclinic Pyroxene in Augitic Rocks, by Whitman Cross, with a Geological Sketch of Buffalo Peaks, Colorado, by S. F. Emmons. 1883, 8°, 40 pp. Price ten cents. 2. Gold and silver conversion tables, giving the coining value of Troy ounces of fine metal, &c., by Albert Williams, jr. 8°. Washington, 1883. ii, 8 pp. Price five cents. STATISTICAL PAPERS. A fourth series of publications having special reference to the mineral resources of the United States is contemplated; of that series the first is this volume: Mineral Resources of the United States, by Albert Williams, jr. 8°. Washington, 1883. xvii, 813 pp. Price 50 cents. Correspondence relating to the publications of the Survey, and all remittances, should be addressed DIRECTOR OF THE UNITED STATES GEOLOGICAL SURVEY, to the WASHINGTON, D. C., October 1, 1883.
