THE IRRIGATION AGE. 



"MOGUL" WINDMILL. 

 Pumping into a Reservoir at Garden City, Kansas. 



The Mogul is less reliable than the 

 tower mill. The direction of the wind is 

 not controlled by the irrigator and the 

 wind is not as strong at the surface of the 

 ground as it is 30 or 40 feet in the air. 



From seventy to a hundred tower 

 mills can be counted from the train as one 

 passes Garden City. The windmill is the 

 popular pumping machine; that is to say

 many windmills on towers as there are of 

 all other kinds of pumping powers com- 

 bined because wind per se is cheap. Con- 



trary to popular opinion, however, cheap 

 wind does not necessarily furnish the 

 cheapest power. 



OTHEE FORMS OF POWER. 



Following in order of power, after the 

 Mogul and tower windmills come the 

 gasoline engines, driving centrifugal or 

 auger pumps for low lifts from creeks or 

 open wells; rotary pumps (positive) for 

 higher lifts, or reciprocal (cylinder) pumps 

 for very high lifts, as at the Groodland state 

 pumping station. These plants, complete,
