The statute approved March 3, 1879, establishing the United States Geological Survey, contains 
the following provisions: 
“The publications of the Geological Survey shall consist of the annual report of operations, geo- 
logical and economic maps illustrating the resources and classification 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.” 
Except in those cases in which an extra number of any special memoir or report has been sup- 
plied to the Survey by special resolution of Congress or has been ordered by the Secretary of the 
Interior, this office has no copies for gratuitous distribution.
