CLASSIFICATION OF THE PUBLICATIONS OF THE UNITED STATES GEOLOGICAL 
SURVEY. 
[Bulletin No. 272.] 
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 the United 
States — folios thereof. The classes numbered 2, 7, and 8 are sold at cost of publica- 
tion; the others are distributed free. A circular giving complete lists may be had on 
application. 
Most of the above publications may be obtained or consulted in the following ways: 
1. A limited number are delivered to the Director of the Survey, from whom they 
may be obtained, free of charge (except classes 2, 7, and 8), on application. 
2. A certain number are delivered to Senators and Representatives in Congress, for 
distribution. 
3. Other copies are deposited with the Superintendent of Documents, Washington, 
D. G, from whom they may be had at prices slightly above cost. 
4. Copies of all Government publications are furnished to the principal public 
libraries in the large cities throughout the United States, where they may be con- 
sulted by those interested. 
The Professional Papers, Bulletins, 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, System- 
atic geology and paleontology; D, Petrography and mineralogy; E, Chemistry and 
physics; F, Geography; G, Miscellaneous; H, Forestry; I, Irrigation; J, Water stor- 
age; K, Pumping water; L, Quality of water; M, General hydrographic investiga- 
tions; N, Water power; 0, Underground waters; P, Hydrographic progress reports. 
This paper is the seventy-fourth in Series B, the complete list of which follows 
(PP= Professional Paper; B=Bulletin; WS= Water-Supply Paper):
