At the Cwmystwith lead mines in Wales I erected, in 1899, a Peltonwheel 5 ft. in diameter, for the purpose of driving the concentration mill,and also a pair of Schrams 12-in. x 24-in. air compressors. The generalarrangement of this plant is shown in Plate II. (fig. 18), which is areduction of the actual
