able perfection and may be used economically where 

 the price of gasoline is reasonable. Engines using 

 crude oil may be most desirable in the localities where 

 oil wells have been found. As the manufacture of 

 alcohol from the waste products of the farms becomes 

 established, the alcohol-burning engine could become 

 a ver}^ important one. Over nearly the whole of the 

 dry-farm territory coal is found in large quantities, 

 and the steam engine fed by coal is an important 

 factor in the ])urn]:)ing of water for irrigation pur- 

 poses. Furtlier, in the mountainous j^art of the dry- 

 farm territory water jjower is very abundant. Only 

 the smallest fracti(jn of it has as yet been harnessed 

 f(jr the generation of the electric current. As electric 

 generation increases, it should be comparatively 

 cas}' for the farmer to secure sufficient electric power 

 to run the pump. This has already become an 

 estalilished j.)ractice in districts where electric power 

 is available. 



During the last h'W }'oars considerable work has 

 been done to determine the feasibility of raising water 

 for irrigation l)y pumjjing. Fortier reports that 

 successful results have been obtained in Colorado, 

 Wyoming, and Montana. He declares that a good 

 type of windmill located in a district where the 

 average wind movement is ten miles per hour can 

 lift enough water twenty feet to irrigate five acres 

 of land. Wherever the water is near the surface 

 this should be easy of accomplishment. Vernon,
