PUBLICATIONS OF UNITED STATES GEOLOGICAL SURVEY. 
[Bulletin No. 228.] 
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 publication; the others are distributed free. A circular giving complete 
lists may be had on application. 
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 classi- 
fied into the following series: A, Economic geology; B, Descriptive geology; C, 
Systematic geology and paleontology; D, Petrography and mineralogy; E, Chem- 
istry and physics; F, Geography; G, Miscellaneous; IT, Forestry; I, Irrigation; 
J, Water storage; K, Pumping water; L, Quality of water; M, General hydro- 
graphic investigations; N, Water power; O, Underground waters; P, Hydrographic 
progress reports. This paper is the twenty-sixth in Series I) and the fortieth in Series 
E, the complete lists of which follow. (PP=Professional Paper, B=Bulletin.)
