1 process print : halftone ; image 9.1 x 12.5 cm

Chinese farmers' ingenious method of irrigation. Where better mechanical appliances are not available a shallow vessel with ropes attached to each side is used to scoop up water from a running stream. Two men swing the pail so that it skims just under the surface of the stream, is brought up nearly full, and emptied with a jerking motion into the channel. This process is repeated with surprising rapidity and smoothness
