in the following series: A, Economic geology; B, Descriptive geology; C, System- 
atic geology and paleontology; D, Petrography and mineralogy; E, Chemistry and 
physics; F, Geography; G, Miscellaneous; H, Forestry; I, Irrigation; J, Water stor- 
age; K, Pumping water; L, Quality of water; M, General hydrographic investiga- 
tions; N, Water power; O, Underground waters; P, Hydrographic progress reports. 
This bulletin is the forty-third in Series A and the fifty-fourth in Series B, the 
complete lists of which follow. (PP= Professional Paper; B=Bulletin; WS=Water- 
Supplv Paper.)
