LETTER OF TRANSMITTAL

DEPARTMENT OF THE INTERIOR,

UNITED STATES GEOLOGICAL SURVEY,

Washington, D. 0. , June 7, 1904..

SIR: I have the honor to transmit herewith the manuscript of a 

bibliography and index of North American geology, paleontology, 

petrology, and mineralogy for the year 1903, and to request that it 

be published as a bulletin of the Survey. 

Very respectfully,

F. B. WEEKS,

Director United States Geological Survey.

BIBLIOGRAPHY AND INDEX OF NORTH AMERICAN 

GEOLOGY,- PALEONTOLOGY, PETROLOGY, AND 

MINERALOGY FOR THE YEAR 1903.

By FRED BOUGHTON WEEKS.

INTRODUCTION,

The arrangement of the material of the Bibliography and Index f Or 

1903 is similar to that adopted for the preceding annual bibliographies, 

Bulletins Nos. 130, 135, 146, 149, 156, 162, 172 (combined in Bulletins 

188 and 189), 203, and 221.

Bibliography. The bibliography consists of full titles of separate 

papers, arranged alphabetically by authors' names, an abbreviated 

reference to the publication in Avhich the paper is printed, and a brief 

description of the contents, each paper being numbered for-index 

reference.

Index. The subject headings, their subdivisions and arrangement, 

are shown in the classified key to the index, w.hich immediately precedes the index. Reference is made in each "entry by author's name 

and number of article in the bibliography.

The series of annual bibliographies has been prepared solely from 

publications received by the library of the United States Geological 

Survey. On January 1, 1903, the writer was placed in charge of the 

library of this organization, and an effort has since been made to procure the publications which were not noticed in the bibliographies of 

previous years, it being known that there were a considerable number 

of omissions of geological papers. Many of these are noted in this 

bulletin. ' . Mr. John M. Mckles has again assisted in the compilation of this 

work, and credit is due him for its careful preparation and completeness.
