[Bulletin No. 262.] 
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 the 
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. Every member of Congress is allotted a certain number, from whom they may 
be obtained, free of charge, on application. 
3. Other copies are deposited with the Superintendent of Documents, Washington, 
D. C, from whom they may be had at practically 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, 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 investi- 
gations; N, Water power; 0, Underground waters; P, Hydrographic progress reports. 
This paper is the thirty-second in Series D and the forty-sixth in Series E, the com- 
plete lists of which follow. (PP= Professional Paper; B=Bulletin. )
