The axle turns upon two uprightpi(5ces of wood, kept steady by a pole stretched across them. The p»a-chlne being fixed, men treading upon the projecting arms, and supportingthemselves upon the l)eam across the uprights, communicate a rotary metion to the chain, the pallets attached to which draw up a constant anucopious stream of water. Another mode of working them, which observed only at Chu-san, was by yoking a buffalo, or other animal, toa large horizontal cog wheel, working into a vertical one fixed on the Chap, Paternoster Pumpa. \f^>\ Bame shaft with the wheel that imparts motion to the chain, as represent-ed in figures 49 and 54.
