THE IRRIGATION AGE.

Making Farming a Science Instead of a 

 Game of Chance in the Great Plains 



In many regions of the Great Plains they 

 are learning that with the limited rainfall 

 and the great variation in the frequency of 

 rains farming is only a gamble or a game of 

 chance. 



But they are beginning to understand that 

 by installing deep well irrigation pumping 

 plants to furnish supplementary irrigation 

 when the droughts come the production of the 

 land can be not only doubled but they may 

 be certain of a full crop every year. 



One of the leaders in this development 

 work is Mr. D. L. McDonald, Hereford, 

 Texas, who has installed over 50 irrigation 

 pumping plants in that vicinity. 



The above illustrations show the develop- 

 ment of one of Mr. McDonald's irrigation 

 wells. Left, at top, drilling the 30-inch well 

 with an "American" rotary drilling machine; 



bottom, installing the "American" deep well 

 turbine centrifugal pump; right, at top, de- 

 veloping the well and producing the under- 

 ground reservoir by pumping out the sand; 

 in center, installing the permanent oil en- 

 gine; at bottom, the installation housed com- 

 plete. 



By learning how to drill and develop these 

 wells and installing in them the most mod- 

 ern pumping machinery many of Mr. Mc- 

 Donald's wells deliver as much as 2,000 gal- 

 lons of water per minute. 



We have prepared a bulletin which de- 

 scribes the most successful methods of de- 

 veloping large capacity deep wells for irri- 

 gation supply in the Great Plains area. This 

 is Bulletin 14i, "Methods of Constructing 

 Large Capacity Deep Wells for Irrigation 

 Pumping in the Great Plains." A copy will 

 be mailed you upon request. 



"American" deep well turbine centrifugal pumps 

 are described in catalog 132. Write for it.
