RAISING WATER.
Rotary machines have been employed for raising water during many years, but hitherto they generally consisted of an immovable cylinder, in which the water is circulated by rotating paddles until it acquires sufficient centrifugal force to elevate it through a pipe. The highest lift attained in this way has been 130 feet, but a recent invention by a young French engineer, M. de Romilly, enables water to be raised 500 feet or more. The new elevator consists of a flat horizontal cylinder or pan, fed with the water to be lifted, and rapidly rotated round a vertical axis by means of a pulley. The motion of the pan causes the water to circulate round its internal walls, and a tube reaching down from the height to which the water is to be raised is brought into the pan, and terminated in a curved nozzle turned towards the circulating liquid. The swirling water, by virtue of its momentum, rushes into the nozzle and ascends the tube.
