FORESTRY AND IRRIGATION 



March 





PUMPING WITH A THRESHING ENGINE. 



saves his property, either by running 

 one of his driven wells, disconnected 

 from the windmill, or perhaps pumps 

 water up from some stream to irrigate 

 his fields, as shown in the accompany- 

 ing cut of a California pumping outfit 

 in operation. 



In regions where streams are more 

 numerous it is frequently of great value 

 to the farmer or the owner of a country 

 residence to force water up from a brook 

 into his house and barn. The hydraulic 

 ram is then employed an old, well- 

 known device, by means of which the 

 momentum of water flowing through a 

 long sloping pipe is employed to force 

 a small part of the same water up to 

 almost any ordinary and reasonable 

 height. 



Only the other day we saw a descrip- 

 tion of the apparatus employed by a 



dairy farmer ten miles from Washing- 

 ton, D. C., who wished to force water 

 300 or 400 yards uphill ^nto a 30,000- 

 gallon tank. He tried rams. They 

 did not supply enough water. He tried 

 a gasoline engine. It was expensive, 

 needed watching, and sometimes went 

 on a strike. He tried a windmill, which 

 proved most unsatisfactory when most 

 needed. Finally he dammed a tiny 

 stream, led the water a hundred yards 

 in a trough, and allowed it to fall on a 

 1 2-foot overshot water-wheel. A triple- 

 cylinder pump was run from the axle 

 by a chain and sprocket. The result 

 was perfectly satisfactory. 



The pump forces 7,200 gallons daily 

 into the tank, which is over a quarter 

 of a mile away and at a considerable 

 elevation from the spring which is the 

 source of supply.
