 Geologic Atlas of the United States— folios thereof. The classes numbered 2, 7, and 8 are sold at cost 

 of iiublication: the others are distributed free. A circular giving complete lists may be had on

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, Eco- 

 nomic geology; B, Descriptive geology; 0, Systematic geology and paleontology; D, Petrography and 

 mineralogy; E, Chemistry and physics; F, Geography; G, Miscellaneous; H, Forestry; I, Irrigation; 

 ,T, Water storage; K, Pumping water; L, tjuality of water; M, General hydrographic investigations; 

 N, Water power; O, Underground waters; P, Hydrographic progress reports. This paper is the
