tion and water-right law, and to make it, by way of comparison, world wide 

 in its application. It is pi^sented in four volumes and consists of 14 distinct 

 divisions, which are as follows: Economic questions relating to irrigation and 

 waters ; ancient and modern irrigation ; classification, definitions, and the na- 

 ture of waters ; rights of the public in waters and water courses ; acquisition 

 and disposal of lands and waters by the United States; the common law gov- 

 erning waters; the civil law governing waters; the appropriation of water for 

 beneficial uses ; the nature, extent, and character of rights acquired to water 

 by appropriation, rights of way, and the pollution of waters : subterranean 

 waters and rights acquired thereto; international, interstate, federal, state, 

 district, and municipal control ; control by private water companies ; adjudica- 

 tion and protection of rights — injuries to rights and remedies therefor; and 

 special features and statutory laws of the arid and semiarid States. 



Elements of western water law, A.- E. Chandler {San Francisco, 1913, pp. 

 150). — This book, intended for advanced students in agricultural or civil engi- 

 neering, contains chapters on the following topics : Early development of the 

 doctrine of appropriation, riparian rights in the Western States, the law of 

 underground waters, the doctrine of appropriation, loss of water rights, water 

 right legislation, water rights on interstate streams, rights of way over public 

 lands for ditches and reservoirs, commercial irrigation enterprises, the desert 

 land act and the Carey act, the reclamation act, irrigation ditches, and the 

 desideratum in legislation regarding the public waters. 



Water laws of the State of Oregon (Salem, Oreg., 1913, pp. 195). — The text 

 of the state laws pertaining to irrigation, drainage, water-power development, 

 and water supplies is given. 



Hydraulics, E. H. Sprague (London. 19lJf, pp. 18Jf, figs. 89; rev. in Engin. 

 Rec, 69 (1914), No. 18, p. 514). — This is a text-book for students and engineers 

 containing chapters on the principles of fluid pressure ; liquids in motion ; dis- 

 charge through orifices, weirs, etc. ; flow in pipes and channels ; and the pressure 

 of water and its application to motors and pumps. 



Station of rural engineering and agricultural hydraulics: [Report of 

 tests], R. Gagey (Bui. Dir. G^. Agr. Com. et Colon. Tunis, 17 (1913), No. 71, 

 Sup., pp. 53-S7).— Tests at the station extending from 189S to 1912 on a large 

 number of agricultural machines and motors, including animal power, and ex- 

 periments in soils and agricultural hydraulics are briefly reported. 



Report of state engineer, Colorado, 1911—12, C. W. Comstock (Bien. Rpt. 

 State Engin. Colo., 16 (1911-12), pp. 363, pis. 10). — This report gives informa- 

 tion on water appropriation and distribution and includes hydrographic and 

 flood data and data on pumping for irrigation, particularly from wells. 



Drainage and irrigation: The duty of water, L. Schmeer (Engin. and 

 Contract., J,l (1914), No. 16, pp. 478~481, fig. i).— The author defines the duty 

 of water, and discusses it under the heads of net duty, influence of methods of 

 irrigation on net duty, methods of estimating net duty, percolation, gross duty, 

 and method of estimating gross duty. Tables and formulas are included. 



Measurement of flowing streams, R. R. Lyman (Utah Engin. Expt. Sta. 

 Bui. 5 (1912), pp. 18, pis. 2, figs. 3). — This bulletin presents in popular lan- 

 guage a simple method for using the weir, and is designed for the use of irri- 

 gators and others concerned in the measurement of flowing water. Tables of 

 discharges in second-feet per foot of weir and of weir dimensions and discharge 

 diagrams are appended. 



An investigation of the use and rating of the current meter, C. P. Rumpf 

 (Engin. News, 71 (1914), No. 20, pp. 1083, 1084. figs. /,).— Rating curves from 

 tests of screw and cup current meters under ordinary conditions of movement
