CLASSIFICATION OF THE PUBLICATIONS OF THE UNITE!) STATES GEOLOGICAL 
SURVEY. 
[Bulletin No. 323.1 
The 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 can be had on application. 
Most of the above publications can be obtained or consulted in the following ways: 
1. A limited number are delivered to the Director of the Survey, from whom they 
can 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. C, from whom they can 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 can be consulted 
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; O, Underground waters; P, Hydrographic progress reports, 
Q, Fuels; R, Structural materials. This paper is the fifty-second in Series E, and 
the fourth in Series Q, the complete lists of which follow (PP= Professional Paper; 
B=Bulletin):
