THE IRRIGATION AGE. 



One well, however, with very salty water occurred 

 in the Rilito valley near Tucson in a district of gen- 

 erally good waters. Recently this well has been 

 pumped freely and is now quite as good as other 

 waters in the neighborhood. In parts of the Casa 

 Grande valley and the Buckeye-Arlington district 

 the first stratum waters are very saline, while those 

 found at greater depth are very much less so. A 

 deep well was put down adjoining the University 

 grounds at Tucson and samples were analyzed from 

 different depths. The water at 700 or 800 feet in 



this case did not differ materially from that found 

 at 100 feet illustrating the uncertainty of applying 

 conditions in one neighborhood to another. 



Water for irrigating cannot be judged solely by 

 the taste, since an injurious amount of black alkali 

 does not reveal itself in this way. Black alkali 

 waters usually make very satisfactory domestic 

 waters, since they are soft and work well with soap. 

 They are not more harmful to the health than other 

 waters with a little, pinch of baking soda added ; in 

 fact, in some cases they may be decidedly beneficial. 



IRRIGATION CONGRESS MEETS IN CANADA 



AS this issue of the IRRIGATION AGE goes to press, 

 the twenty-first annual meeting of the Inter- 

 national Irrigation Congress is being held at Cal- 

 gary, Alberta. 



A program covering four days has been ar- 

 ranged by the officers. A. A. Jones, first assistant 

 secretary of the interior, is the most prominent 

 American scheduled to appear. Among other 

 Americans on the program are : J. M. Kennedy, 

 Montana Commissioner of Agriculture; J. B. Case, 

 of Kansas; D. W. Ross, of California; John Fair- 

 weather, of California ; George A. Snow, of Utah ; 

 J. T. twinkle, of Oregon ; F. H. Newell, Kurt Grun- 

 wald, of Colorado; H. B. Walker, state irrigation 

 engineer of Kansas ; J. C. Nagle, chairman of the 

 board of water engineers of Texas ; John Widstoe, 



president of the Utah Agricultural college ; L. 

 Newman, of Montana ; F. C. Finkle, of California ; 

 John Barrett, of Washington, D. C., and E. F. Ben- 

 son, of Washington. 



The balance of the program is filled by Ca- 

 nadian speakers, provincial officers and employes of 

 the Canadian Pacific Railway and its land com- 

 panies. 



The European war has had a depressing effect 

 on the preparations for the congress, and almost 

 resulted in its complete abandonment. As it is, 

 there will be no distinguished visitors from abroad, 

 such as characterized the meetings of the congress 

 in the days when it was an honored institution of 

 the United States and working heart and soul in 

 behalf of the irrigated West.
