A method of determining storm-water run-off, C. B. Buerger {Trans. Amer. 

 Boc. Civ. Engin., 78 (1915), pp. 1139-1205, pis. 2, figs. 9).— The author develops 

 a formula for storm-water run-off of the form q+Nq%=P, in which q is the 

 run-off in cubic feet per second per acre and N and P are functions of the 

 variable elements of topography, rainfall, etc Diagrams are given which afford 

 a ready means of obtaining results from the formula. 



Daily river stages at river gauge stations on the principal rivers of the 

 United States, 1915 and 1916, A. J. Henry {U. S. Dept. Agr., Weather Bur., 

 Daily River Stages, IS {1915), pp. 176; U (1916), pp. 27S).— These are the 

 thirteenth and fourteenth parts of the series of river gauge readings main- 

 tained by the Weather Bureau. 



Surface water supply of St. Lawrence River Basin, 1916 {U. S. Geol. Sur- 

 vey, Water-supply Paper ^34 {1911), pp. 130-{-XXXII, pis. 3).— This report, 

 prepared in cooperation with the States of Minnesota, Wisconsin, New York, 

 and Vermont, presents the results of measurements of flow made on streams 

 tributary to Lakes Michigan, Huron, Erie, Ontario, and Superior, and to the St. 

 Lawrence River, during 1916, together with the usual list of gauging stations 

 and publications relating to water resources. 



Surface water supply of Hawaii, July 1, 1913, to June 30, 1915, G. K. 

 Larkison {V. S. Ocol. Survey, Water-Supply Paper 430 {1917), pp. 329).— This 

 report presents the results of measurements of flow made on certain streams
