THE IRKIGATION AGE. 



A View of the First Pumping Plant on the Ranch of Tarr & Sellers, Platteville, Colo. A tee is placed in the 

 pipe line 100 feet from the pump. The elevation of the tee above the pump at this point is 12 feet. A Dempster 12 

 H. P. Horizontal Four Cycle Gasoline Engine and a No. 5 Gould Submerged Vertical Centrifugal Pump are lifting 

 120 inches of water per minute. At this rate one acre would be covered one inch deep in about 20 minutes. One 

 acre of water a foot in depth would be pumped in about four hours. 



RESULTS OF IRRIGATING WITH A SUCCESSFUL 

 PUMPING PLANT. 



The 12 horsepower horizontal gasoline engine and a 

 No. 5 centrifugal pump sold by the Dempster Mill Manu- 

 facturing Company, Beatrice, Neb., to Tarr & Sellers, was 

 installed late in 1908 and in the season of 1909 was used 

 to irrigate 60 acres of wheat and 12 acres of potatoes. 



gasoline and lubicating oil was 91 cents per acre for 

 pumping water to the wheat through 600 feet and 800 

 feet of 10-inch pipe at elevations of 18 feet and 25 feet 

 respectively. For the 12 acres of potatoes the cost was 

 slightly under $1 per acre. The cost for repairs was 

 nothing. The crop of wheat averaged over 35 bushels 

 per acre, but no report on the potato crop was received. 

 With the engine and pump and plenty of available 

 water the operation has all the advantages of the ditch.
