486 EXPERIMENT STATION RECORD. 



It is concluded that by the use of tube wells worked with properly selected 

 pumps and oil engines lift irrigation can be effected at a rate considerably 

 cheaper than by any other method in use in India. 



Cost of water per acre (West. Engin., 2 {1913). No. 5, pp. 57.9-385 ) .—Tables 

 of data are given comparing the cost of water per acre as supplied by a large 

 number of recently constructed private, Carey Act, and United States Recla- 

 mation Service irrigation projects. This cost averages nearly $53 on the pi'ivate 

 and Carey Act projects, as against $41 on the Reclamation Service projects. 

 Summing up the advantages of lower first cost, absence of interest, more de- 

 pendable water supply, and more complete works for the Reclamation Service 

 projects, it is concluded that water is obtained from these projects at from 

 one-half to two-thirds the cost of that from the private and Carey Act projects 

 listed. 



Water resources (Rpt. Oreg. Conserv. Com., 1912, pp. 34-52, figs. 4). — It is 

 stated that the average precipitation in eastern Oregon ranges from 8 to 15 

 or 20 in. and that there are only 3 general localities where there is a large 

 excess of water which can not be utilized, viz, the lower Klamath, lower 

 Deschutes, and lower Grande Ronde rivers, on account of low elevation. In 

 practically all the rest of eastern Oregon there is an excess of land that can 

 be canaled over the amount of available irrigation water. In western Oregon 

 there is a heavy run-off which is insufficiently distributed throughout the year 

 to be of the highest utility for irrigation. 



Records of river discharge and a brief summary of the storage and irriga- 

 tion possibilities of the most important streams of the State indicate that there 

 is a sufficent water supply to irrigate 4,000,000 acres of land. An inventory 

 of the available irrigation waters of the State is given in tabular form, as is 

 also a classification of the irrigated areas by the character of each enterprise. 

 The latter shows that only 7 per cent of the total has been watered through 

 the United States Reclamation Service, the State under the Carey Act, and irri- 

 gation disti'icts, whereas 11.3 per cent has been watered by commercial projects 

 and S1.7 per cent by individual or cooperative enterprises. 



A suggested remedy for these conditions embodies a constitutional amend- 

 ment providing for a bond issue for irrigation and water power development 

 by the State, the money expended to be secured by a lien on the land developed 

 or works constructed, and the woi-k to be carried on in cooperation with the 

 Reclamation Service. 



A preliminary report on the Quincy Valley irrig'ation project (Wash. Geol. 

 Survey Bid. IJ/, 1912, pp. 49, P^^- 7). — This report includes papers on the soils 

 of the valley, by A. W. Mangum ; chemical analyses of the soils, by H. K. Ben- 

 son ; climate, by E. J. Saunders ; and irrigation problems, by J. Jacobs. Maps 

 and illustrations of the project accompany the report. 



Annual irrigation revenue report of the Government of Bengal for the 

 year 1911-12 {Ann. Irrig. Rev. Rpt. Bengal, 1911-12, pp. 6+17+33. pi. 1).— 

 This report states that the capital outlay on major irrigation works up to the 

 end of March, 1912, amounted to $3,603,176, the works comstructed for this out- 

 lay comprising 2 weirs, 9S.75 miles of main and branch canals, and 254.5 miles 

 of distributaries. The total receipts from these works for the year amounted to 

 about $90,000 and the working expenses to about $95,600. The area irrigated 

 was 80,975 acres, an increase of 7,035 acres over the preceding year, due to 

 insufficient rainfall at the beginning of the irrigation season. 



The capital outlay on minor irrigation and navigation works was about 

 $128,000 during the year and aggregated $3,720,000. The receipts for the year 

 amounted to about $204,000 and the working expenses to about $141,500,
