[Professional Paper No. 54.] 
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 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:

whom they can be had at practically cost. 
4. Copies of all Government publications are furnished to the principal public libraries in the 
large cities thruout 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, Systematic geology and paleontology; D, Petrography 
and mineralogy; E, Chemistry and physics; F, Geography; G, Miscellaneous; H, Forestry; I, Irriga¬ 
tion; J, Water storage; K, Pumping water; L, Quality of water; M, General hydrographic investiga¬ 
tions; N, Water power; O, Underground waters; P, Hydrographic progress reports. This paper 
is the seventy-sixth in Series A and the ninety-fifth in Series B, the complete lists of which follow 
(PP=Professional Paper; B=Bulletin, WS=Water-Supply Paper):
