BIBLIOaRAPHY AND INDEX OF NORTH AMERICAN 

GEOLOGY, PALEONTOLOGY, PETROLOGY, AND 

MINERALOGY FOR THE YEAR 1902.

By FRED BOUGHTON WEEKS.

INTRODUCTION.

The arrangement of the material of the Bibliography and Index for 

1902 is similar to that adopted for the previous publications (Bulletins 

Nos. 130, 135, 146, 149, 156, 162, 172, 188, 189, and 203). Several 

papers that should have been entered in the previous bulletins are 

here recorded, and the date of publication is given with each entry.

Bibliography. The bibliography consists of full titles of separate 

papers, arranged alphabetically by authors' names, an abbreviated 

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

description of the contents, each r>aper being numbered for index 

reference. .

Index. The subject headings, their subdivisions and arrangement, 

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

and number of article in the bibliography.

Mr. John M. Nickles has assisted in the compilation of this work, 

and credit is due him for its careful preparation and completeness

.PUBLICATIONS OF UNITED STATES GEOLOGICAL SURVEY.

[Bulletin No. 221.]

The serial publications of the United States Geological Survey consist of (1) Annual 

Reports, (2) Monographs, (3) Professional Papers, (4) Bulletins, (5).Mineral-Resources, (6) Water-Supply and Irrigation Papers, (7) Topographic Atlas of United 

States folios and separate sheets thereof, (8) Geologic Atlas of United States 

folios thereof. The classes numbered 2, 7, and 8 are sold at cost of publication; the 

others are distributed free. A circular giving complete lists may be had on application.

The Bulletins, Professional Papers, and Water-Supply Papers treat of a variety of 

subjects, and the total number issued is large. They have therefore been classified 

into the following series: A, Economic geology; B, Descriptive geology; C, Systematic 

geology and paleontology; D, Petrography and mineralogy; E, Chemistry and physics; F, Geography; G, Miscellaneous; H, Forestry; I, Irrigation; J, Water storage; 

K, Pumping water; L, Quality of water; M, General hydrographic investigations; 

N, Water power; 0, Underground waters; P, Hydrographic progress reports. This 

bulletin is the twenty-fifth in Series G, the complete list of which follows (all are 

bulletins thus far): .
