Referring to the illustration, the gas enters the washer by the pipe, A, which terminates in the form of a [Symbol: inverted T]. One end (a) of this pipe is bolted to the center of one of the sides of the cylindrical portion of the case, in which there is a hole of similar diameter to the pipe; the other (a') being formed by the face-plate of a stuffing-box, B, through which passes the central shaft, C, supported by the plummer-block, D, as shown. This shaft has upon its opposite end a plate perforated with holes, E, which is fixed upon the flange of a horizontal pipe, F. This pipe is closed at the other end by means of a plate, E', furnished with a spindle, supported by a stuffing-box, B', and carrying a fly-wheel, G. The central pipe, F, is perforated with a number of small holes. The gas entering by the pipe, A, makes its way into the central pipe through the openings in the plate, E, and passes into the cylindrical case through the small holes in the central pipe, which carries the brooms, H. These are caused to rotate rapidly by means of the pulley, I; and thus a constant shower of water is projected into the cylindrical case. When the gas has been several times subjected to the washing process, it passes off by the pipe, K. Fresh cold water is supplied to the vessel by the pipe, L; and M is the outlet for the tar.--Journal of Gas Lighting.


THE WIND MILL.

[Footnote: A paper read before the Engineers' Club of St. Louis, 1884.]

By JAMES W. HILL.

In the history of the world the utilization of the wind as a motive power antedates the use of both water and steam for the same purpose.

The advent of steam caused a cessation in the progress of wind power, and it was comparatively neglected for many years. But more recently attention has been again drawn to it, with the result of developing improvements, so that it is now utilized in many ways.
