[Continued from pago 158.] The annexed engraving is a side elevation of a series of buckets for dipping and carrying up water from a stream. They are placed upon an endless chain, and run over pulleys as represented. The upper pulley, A, has cogs on its periphery to take into the links of the chain. This is the pulley, which is moved by a handle secured on the axle. The lowerpul-ley, B, is only a guide for the buckets, I H G, passing around it. The buckets dip up the water, carry itup to the upper pulley, and discharge in a horizontal line with the top of the working pulley, where it flows into and out of a box, F, as fast as it it is discharged. There seems to be strange opposition to railroads in cities; why this feeling ashould exist we cannot divine.
