rainfall is from 5 to 20 inches greater and the evaporation loss pro- 

 portionately less, the case is quite different. 



I am, of course, not referring to the sub-surface water, the under- 

 flow of the large rivers, and that of the Loup Fork Tertiary, the 

 unshaded area on the map. These waters are already stored and only 

 need to be brought to the surface. They are the hope of western 

 Kansas, and yet not the only hope, for we believe that much of the 

 surface water now unused, will in the future, when the demand for it 

 is sufficiently great, be stored and used for irrigation.
