THE HYDKAULIC KAM. 



The hydraulic ram is a machine for forcing a portion 

 of a brook or stream to any required elevation and distance, 

 when the requisite head or pressure can be obtained. 



Wherever a large spring or a limited but constant stream 

 is at hand, by which a fall of four or five feet may be pro- 

 duced, by building a dam or otherwise, a portion of the 

 water of such spring or stream may be raised to a perpen- 

 dicular height of more than 100 feet by its own power, 

 through the agency of the water-ram. Thus, a stream in 

 a deep valley, or a rivulet or brook situated some distance 

 below a point where it is desired to have a cistern or re- 

 servoir, may be made to raise a part of its water by one 

 of these machines. From such a cistern or reservoir the 

 water may afterwards be conveyed to any part of the pre- 

 mises below it, and applied for the purpose of irrigation, 

 watering of stock, manufactories, or domestic or ornamental 

 use. 



The power of the ram, and the height to which it will 

 raise the water, as also the quantity raised, are in propor- 

 tion to the volume of the stream and the head or fall ob- 

 tained. 



The ram is applicable where no more than 18 inches fall 

 can be obtained.
