one bar of the cuttingshears. The cylinder which carries the cutting-knives makes about 130 revolutions per minute, and the quantity of bark cut is about 1,600 pounds per hour. Bark-cutting machine. Bark′er's mill. （Hydraulic.) The Barker mill has attained celebrity rather as an interesting illustration of the principle of reaction or recoil than as a practically useful machine. It, however, has the essential features of the famous turbines and other reaction wheels. Barker's mill. It consists of a vertical tube having an open funnel at top, and branching at its lower end into two horizontal radial tubes. Each of these horizontal arms has a round hole on one side of it, the two holes being opposite to each other; and the vertical tube, being mounted on a spindle or axis, is kept full of water, flowing into the funnel at the top. The issue of water from the holes on opposite sides of the horizontal arms causes the machine to revolve rapidly on its axis with a

a softened steel roller placed in apposition to the said die. The soft roller has the design in cameo, is hardened, and forms a mill, which is capable of delivering an intaglio impression upon a plate or roller, as above stated. The process was invented by Jacob Perkins, and adapted to engraving cylinders for calico-printing by Locket of Manchester, England. See under the following heads: — Amalgamator.Oil-cake mill.

ginal steam-engine is the Aeolipile of Hero, exhibited in the Serapeum of Alexandria, 150 B. C. It is a true rotary steam-engine, and there are quite a number of late patents in which the same principle is maintained. Originally it was a philosopher's experiment, and late attempts to utilize it have not been successful from some cause. The principle is the same as that of the turbine or reaction water-wheel, which is a very effective mode of applying the power of a head of water. (See Barker's mill, page 231.) In the Aeolipile a pressure of steam is maintained internally, and the rotation is due to the recoil of the wheel in a direction opposite to that of the issuing steam. The same description will answer for the turbine, substituting water for steam in the description. The agencies differ in this respect; the steam is elastic, and the water otherwise. Whether that will account sufficiently for the success of the latter and the want of success of the former the writer is not a

otion a train of gearing which moves a series of indexes that point out on their appropriate dials the quantity of fluid delivered. See gas-meter; liquid-meter; spirit-meter. Class 1. Siemens and Adamson's meter acts on the principle of Barker's mill. The water is conveyed by a tube a to a horizontal drum d, rotating on a vertical shaft c, having at its upper end a worm which communicates motion to the registering gearing. The drum has three or more tangential apertures at its peripheryoke is 10 feet. The water for driving it is conducted by pipes from a reservoir on a neighboring hill, and ascends in the column of masonry shown to the left of the wheel. Water-wheels are of many kinds. See under the following heads:— Barker's mill.Overshot wheel. Bascule.Persian wheel. Bottom-discharge water-wheel.Pitch-back wheel. Breast-wheel.Radial-piston water-wheel. Bucket-wheel.Reaction water-wheel. Center-discharge wheel.Scoop water-wheel. Chapelet.Screw-elevator. Danaide
