KUEAL ENGINEERING. 785 



To relieve the situation a system of local, state, and federal aid is favored 

 by the author, the general features of which are suggested as follows: "(1) 

 Provision for the segregation for reclamation of tracts of public laud as is now 

 done iinder the Carey Act; (2) provision for the reclamation of similar tracts 

 of state or private lands, or of tracts partly public and partly private; (3) 

 provision for the ci*eation of districts composed of such lands, in general like 

 the present irrigation districts; (4) provisions for the submission of pro- 

 posals for the creation of such districts and the construction of works to 

 .supply the lands with water in somewhat the same manner as Carey Act pro- 

 posals are now submitted; (5) provision for the ajiproval of such proposals by 

 all the contributing agencies and for the pledging of these agencies to con- 

 tribute the amounts agreed upon; (G) provision for the issue of bonds which 

 shall be made in lien on the lands of the districts to be enforced by taxation 

 as is now done in irrigation districts; (7) provision for the disposal of lands to 

 settlers subject to the bonds issued to secure funds for construction; and (8) 

 provision for the enforcement of the lien on the land in case there is default in 

 the payment of interest or principal." 



Irrigation possibilities in Kansas, H. B. WxIlkep. {Bien. Rpt. Kans. Bd. Ayr., 

 19 (lOlS-l-i), pp. 307-S16, figs. 5). — The author emphasizes the importance of 

 first developing the areas of Kansas in which water may be obtained for irriga- 

 tion by pumping from relatively small depths, and is of the opinion that farm- 

 ing methods, to utilize the available water supplies most economically, should be 

 intensive.

 gation, B. P. Walker (Bien. Rpt. Kam. Bd. Agr., 19 (1913-14), PP- 301-306,

[Alfalfa irrigation experiments] {Neto Mexico St a. Rpt. 1915, pp. 45-49, 

 fig. 1). — The amounts of water applied in irrigation experiments on 46 plats of 

 alfalfa, conducted in cooperation with the Irrigation Investigations of this 

 Department, are reported in tabular form. The plats varied in area from 

 1,980 to 14,040 sq. ft. An average of 0.38 acre-feet per acre per irrigation was 

 applied to the lirst 28 plats and of 0.304 acre-feet per acre per irrigation to the 

 remainder. Five irrigations were made. From the irrigation standpoint the 

 results were deemed unsatisfactory, ' 



Tests of a proportional weir (Engin. News, 74 (1915), No. 22, pp. 1018, 1019, 

 figs. 3). — ^Tests of two proportional-flow weirs of the Rettger type (E. S. R., 

 31, p. 784) are reported, both being 3i ft. long on the crest, but dilfering in 

 height from the crest to the curve of the side. 



The results as graphically reported indicate the approximate proportionality 

 of discharge to head. For the higher heads (above 1 ft.), the coeflicients of the 

 smaller weir are about 2.4 per cent higher than for the larger weir. The 

 gi-adual increase in coefficient as the head increased was found to be not due to 

 velocity of approach. 



Report of the acting commissioner for water conservation and irrigation 

 for the year ended June 30, 1915, H. H. Daee (Rpt. Act. Comr. Water Conserv. 

 and I nig. [N. S. Wales], 1914~15, pp. 109, pis. 16).— This report covers the 

 physical and financial status of established and projected irrigation schemes 

 and the extent of artesian and shallow boring during the year from July 1, 

 1914, to June 30, 1915. Private works for the conservation and distribution of 

 water for irrigation and stock watering purposes ai-e also reported upon.
