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 bo 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 famished 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 Keports, as for all other executive documents.

Of these annuals there have been already published: '

BULLETINS.

In its Bulletins the Survey will print such papers relating to the general purpose of its work as do 

not properly come under the heads of ANNUAL REPORTS or MONOGRAPHS.

The Bulletins will each 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 at the top, and at the 

bottom, one which belongs to it in the volume.

Of this series of Bulletins there has already been published:

1. On Hypersthene-Andesite and on Triclinic Pyroxene in Augitic Eocks, by Whitman Cross, with 

a Geological Sketch of Buffalo Peaks, Colorado, by S. F. Emmons, Washington, 1883, pp. 1-42, 2 

plates, 8°. Price ten cents.

The following paper forms No. 2. Its price is five cents. '

Correspondence relating to the publications of the Survey, and all remittances, should be addressed
