Profile surveys along Henrys Fork, Idaho, and Logan River and Black- 

 smith Fork, Utah (C7. S. Geol. Survey, Water-Supply Paper 420 (1916), pp. 

 5-8, pis. 10). — This report, prepared under the direction of W. H. Herron, de- 

 scribes the general features of the Snake River basin and the Logan River 

 basin and gives plans and profiles of Henrys Fork above St. Anthony, of the 

 outlet of Henrys Lake, Idaho, of Logan River above Logan, and of Black- 

 smith Fork, above Hyrum, Utah. 



Profile surveys in 1915 along the Rio Grande, Pecos River, and Mora 

 River, in New Mexico {U. S. Geol. Survey, Water-Supply Paper 421 (1916), pp. 

 5-11, pis. 11 ) . — This report, prepared under the direction of W. H. Herron, con- 

 tains plans and profiles from surveys made in 1915 of the Rio Grande in 

 the vicinity of Buckman, N. Mex., and from Embudo, N. Mex., to the Colorado 

 state line, of the Pecos River above Alexander Valle Grant, N. Mex., and of 

 the Mora River from its mouth to the east boundary of Mora Grant, N. Mex. 



Irrigation field laboratory at Denver, Colorado, R. B. Sleight (Engin. News, 

 76 (1916), No. 23, pp. 1080-1082, figs. 5).— Tliis laboratory, which is part of the 

 equipment of the Irrigation Investigations Division of the Office of Public Roads 

 and Rural Engineering of the U. S. Department of Agriculture, is described 

 and some of the important features illustrated. 



Concrete pipe irrigation systems (Jour. Electricity, 57 (1916), No. 12, pp. 

 219-221, figs. 6). — The manufacture of concrete pipe for use in irrigation dis- 

 tribution systems is discussed, and diagrams are given showing the carrying 

 capacity in cubic feet per second, miners' inches, and gallons per minute of 

 concrete pipe varying in diameter from 6 to 24 in. and with a slope varying 

 from 0.5 to 30 ft. per 1,000 ft. The value of n in Kutter's formula used is 

 0.0135. 



[Competitive tests of (commercial) overhead irrigation systems in 1914], 

 E. Krugek and A. Nachtweh (Arb. Deut. Landw. Gesell., No. 276 (1915), pp. 

 87, figs. 55). — This paper includes a general discussion of irrigation and irriga- 

 tion systems and a description of overhead irrigation systems with prices. It 

 also reports tests of four commercial types of overhead irrigation systems. 



Malheur and Owyhee projects, irrigation and drainage, J. T. Whistler and 

 J. H. Lewis (Oreg. Cooper. Work, Dept. Int. U. S. Reclamation Serv., 1916, Feb., 

 pp. XII+13-201, pis. 52, fig. 1). — This report, prepared in cooperation with the 

 State of Oregon, gives the results of investigations for the irrigation from the 

 Malheur River of Malheur Valley lands in the vicinity of Vale and Ontario, 

 Oreg., and of lands in the vicinity of Nyssa from the Owyhee River. 



"The Malheur project includes approximately 39,150 acres of irrigable land, 

 of which approximately 31,600 acres are the first development and 7,550 acres 

 a later extension of the first development. . . . The present plans are to use 

 the river as the main distributary. . . . 



" An agricultural and soil survey of the lands under the proposed project 

 shows the fertility of the lands and at the same time the necessity for drain- 

 age. The long seasons and fertility of the soil make it capable of fairly in- 

 tensive development. . . . The duty adopted for the gravity lands is 2.6 ft. in 

 depth during the irrigating season ; for the pump lands 2.1 ft. in depth for 

 the season. The distribution losses are estimated at 20 per cent of the water 

 taken out at the heads of the laterals. The seepage loss for earth sections is 

 estimated at 1 ft. in depth per day over the wetted area of canals and for con- 

 crete lined canals 1 in. in depth. . . . The yearly diversion use for the develop- 

 ment of the full project or 39,150 acres Is 161,400 acre feet. . . . The reservoir 

 capacity required is 159,000 acre-feet. . . . The total cost of the entire project, 

 including drainage, is $1,438,458, an average cost of approximately $37 per 

 acre. . . .
