BARKER'S MILL Ger. Sryiiers ^Vasserad) . A water-wlieel in- vented by Dr. Barker toward the end of the Seventeenth Century. It is represented in its sim- plest or typical form in the cut. There is a metal pipe, terminating at its lower end in a steel spin- dle, which rests on a metal block, and is kept in a vertical position by another spindle, at its upper end, which passes through the frame of the machine, so that the pipe can easily revolve around its axis. Near its lower end. two smaller pijies or arms are inserted, which project horizontally from it, and these have eacli, at the outer extremity, a hole or fine nozzle open- ing toward opposite sides. The water is su])- jjlied from a reservoir which opens into the

upper part of the vertical tube, whence it issues from the lower orifices. The reaction caused by the water gushing from the arms forces them backward, and gives to the whole macliine a rotatory motion. This reaction is much the same as is seen in the recoil of a gun when fired, or in the pushing back of a small boat by the foot on stepping ashore.
