Hydraulic Ram.

A hydraulic ram can only be operated by a running stream br fall of water. The ram is operated by a stream carried into it by a pipe ten or twelve feet long; this stream lifts a valve as soon as it lias gained sufficient 'velocity, and shuts the pipes. The flowing stream, being thus suddenly stopped, is changed in its course into an air chamber, in which is a valve that is opened by the diverted stream As soon as this stream exhausts its force this valve closes, and the pressure of the condensed air in the chamber forces the water which has entered from the feed pipe into the discharging pipe. Then the valve in the feed pipe, being no longer pressed by the stream, drops, and the stream begins to flow again, and the process is thus repeated several times every minute. In this way about onesfeventh of the water in the drive pipe is raised to any desired height, the quantity of water being in proportion to the height of the delivery, less as the height is greater.—[New York Times. >
