pipe and carrying the water with its force. It also

 through the pipes in torrents. 

 It is suitable to be used in wells 

 of any depth, and any number 

 of wells at any distance apart 

 can be operated from one en- 

 gine. It is claimed that by this 

 system more water can be raised 

 than by any other, but to the 

 writer's mind this claim is not 

 wholly clear. Another scheme 

 is Merrill's pneumatic system, 

 by which water may be elevated 

 from as many sources as may 

 be desired. Fig. 91 represents 

 two sources, with wind and 

 gasoline engine power, arranged 

 to use separately or in combina- 

 tion. The plan is said to be

 the air-pipe leading to the well; 

 C, the injedlor in the bottom of 

 the well ; Z?, a similar arrange-

 the discharge pipe, and F\s the

 power can be utilized, by gear-

amount of work, such as churning, grinding, etc. 



One man can attend to the whole outfit, and if the
