sources, (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

Most of the above publications may be obtained or consulted in the following ways:

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 phys- 
ics; 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 
paper is the seventy-third in Series C, the complete list of which follows. (PP= 
Professional Paper; B= Bulletin; WS= Water-Supply Paper.)
