A central has a circular sweep-pole, towhich a mule is attached. Cogs on the centralshaft engage others on a horizontal shaft, and oper-ate the wheel u)ion which traverses a continuousrope furnished at intervals with jars or woodenbuckets. The rope descends on one side with emjitybuckets and rises on the other side with full ones,which discharge into a chute leading to the wheels are kept going day and night by relaysof men and mules ; in some cases being the jointproperty and care of the inhabitants of a wholevillage. The great bucket-wheel (b, Fig. 3334) employedby Perronet at the construction of the Bridge of Fig. Bucket-Wheels. Neuilly, France, was 16J feet in diameter, 4i feetin width, and had 16 buckets and 118 cogs. Thewater-wheel by which the bucket-wheel was drivenwas 18 feet in diameter and had 128 cogs. The float-boards were 20 feet long, 3 feet wide, and were set atan angle of 15° with the radius. The lantern-wheelswhich acted as pinions to the large cog-wheels of thebucket-wheel and water-wheel were 4 feet in dianj-eter and had 30 trundles. The axle of the trundleswas 12 inches in diameter, and varied in length ac-cording to the relative proximity of the water-wheeland the bucket-wheel. The former was in the Seine, NOlllUM. 1534 NOYL. anil was rotated hy the ciiiTont of the river ; the lat-ter was in one of the cotier-(ianis which were con-structed for
