Neighborhood irrigating systems, J. W. Swaeen {Toton and Country Jour,, 

 28 (1912), No. 19, pp. //, 5, figs. 3). — This article discusses the relative advan- 

 tages and disadvantages of the corporation canal systeru, the individual pump-

 cooperative pumping is the cheapest and most advantageous. 



Savage irrigation in Luzon, H. Wright (Sci. Amer., 106. {1912), No. 5, p. lOS, 

 figs. Ji). — This ai-ticle describes the irrigation of rice terraces as practiced by 

 the Ifugaos of Luzon. These are works of considerable magnitude, and some 

 of the terraces show reijiarkable engineering. The works show progress in the 

 art of irrigation as they irrigate and fertilize in one operation. 



The Laramie-Poudre tunnel, B. G. Coy {Proc. Amer. Soc. Civ. Engin., 38 

 {1912), No. 3, pp. 217-230, pJs. 6, figs. 2). — This paper discusses the location, 

 construction, cost, and method of operation of an irrigation tunnel in Colorado, 

 v/hich diverts a part of the waters of the Laramie River and tributaries into 

 the Cache la Poudre River, thereby reenforcing the supply of the latter river 

 for irrigation purposes in case of shortage. This tunnel is of nearly rectangular 

 cross-section, 7 A ft. high by 9* ft. wide, has a grade of 1.7 per cent and a 

 capacity of 800 cu. ft. per second, and is 11,306 ft. long. 



Report of the State Board of Irrigation of Nebraska, 1909-10, E. C. Sim- 

 mons {Bien. Rpt. Bd. Irrig. Nehr., 8 (1909-10), iW- 201, fig. i).— This report 

 covers the irrigation administration in Nebraska in 1909-10, reporting action 

 on claims and applications for water and a large amount of data from measure- 

 ments of the principal streams of the State. Accompanying this report are a 

 list of recommendations by the irrigation board for the revision of the state 

 irrigation laws, and a list of miscellaneous water measui'emeuts with con- 

 venient equivalents. 



Second biennial report of the territorial engineer of New Mexico, 1909—10, 

 V. L. Sullivan (Bien. Rpt. Ter. Engin. N. Mcx., 2 (1909-10), pp. 188+67, figs. 

 61). — This report covers the operation of the Carey Act in New Mexico, the 

 district irrigation laws, proposed irrigation and power projects, the scope of 

 irrigation and power development work, and reports on the Hondo and Rayado 

 hydrographic surveys, the methods and cost of road construction, and water 

 supply records of the principal streams of the State. 



Fourth biennial report of the state engineer of North Dakota, 1909—10, 

 T. R. Atkinson (Bien. Rpt. State Engin. N. Dak., // (1909-10), pp. 110).— 

 This report gives the scope of irrigation and drainage in North Dakota in 

 1909-10, including data from the hydrographic investigations of the principal 

 streams. 



Irrigation and drainage, L. A. B. Wade (Rpt. Dept. Puhlic Works N. S. 

 Wales, 1909, pp. 56-67 ; 1910, pp. 55-83).— This portion of the reports deals with 

 the progress of irrigation and drainage improvements in New South Wales in 

 3909-10, gives the details of the construction of works on different streams and 

 .drainage areas, and discusses the methods of preliminary investigations, sur- 

 veys, and estimates for proposed undertakings. 



Methods of tile draining gumbo, hardpan, and seepy land in Kansas 

 (Engin. and Contract., 37 (1912), No. 13, pp. 555-357).— This is an abstract 

 from a paper read before the Kansas Engineering Society, by H. B. Walker of 

 the Kansas State Agricultural College. It discusses the methods by which the 

 soils in Kansas may be tile drained, and gives general directions for making
