Bovill, in England, lessened the loss of flour dust by making a cloth par-tition in the dust room ; and Perigault saved considerable flour by leadingthe dusty current through a room having several partitions, which, rapidlychanging the direction of the current, causes a deposit of the flour. Tolessen the formation of paste, double walls were provided for the dust pipesand dust rooms, and even steam-heating pipes supplied. High-Pressure Aspiration.—The Behrns & Brehmer high-pressureaspiration device, illustrated herewith, is intended to afford perfect cooling, ven-tilation and freedom from dust.

In this instance, cc and ddrepresent the stones, the upper one being the runner, and bb the grinding^surfaces. A fan exhausts the air through the pipe, a, from the millstone hoop,while fresh air re-enters through the eye of the millstone and passes betweenthe grinding surfaces, as shown by the direction of the arrows in the engrav-ing. In order to make the supply current of fresh air as strong as possible,the hoop is made air-tight, and suitable connections and fittings are employedfor the inlet as well as the openings of the chop discharge. For the inlet thisis accomplished by means of two V-shaped cast-iron rings, well fitted lower ring, h, is fastened to the running stone, while the upper one, /, isriveted to a leather cylinder suspended from the top of the hoop. A smallchain fastened to the side of the upper ring prevents it from discharg
