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 G eological Survey shall consist of the annual report of operations, geological 

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 bo 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."

On July 7,1882, the following joint resolution, referring to all Government publications, was passed 

by Congress:

"That whenever any document or report shall be ordered printed by Congress, there shall be printed, 

in addition to the number in each case stated, the 'usual number' (1,900) of copies for binding and 

distribution among those entitled to receive them."

Except in those cases in which an extra number of any publication has been supplied 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.

RECORD OF NORTH AMERICAN GEOLOGY FOR 1891.

BY NELSON HORATIO DARTON.

INTRODUCTORY.

This work is the continuation of the record for 1890,' and comprises publications received during the year 1891.

The literary scope of this record includes geologic publications 

printed in North America, and publications on North American 

geology wherever printed. Purely paleontologic or mineralogic 

papers are omitted.

The entries are comprised in the two following classes, all arranged 

in a single alphabetic sequence:

I. Principal entries. Consisting of full titles of separate contributions classified by authors, together with an abbreviated reference 

to the containing publication and a short note descriptive of the 

geologic contents. Imprint dates are given only when other than 

1891, and size of page when other than octavo. The extent of papers 

less than a page in length is indicated thus: ^ p., % col., 3 lines.

II. Subject references. Each consisting of a condensed title of 

paper, and the author's name for cross-reference to a principal entry. 

These are essentially index references, but they are entered under 

a limited number of headings, of which a classified key is given on 

the next page.
