The waste at the collieries in Schuykill and Luzerne counties, Pennsylvania, is believed to be over one million tons annually, worth LI,000,000. A small kind of coal called Burgie is used in this . country for burning in engines. Coal dust or slack ground in a mill is manufactured in the districts of ]\1 anchester, Wigan, Barnhill. <tc., and used by ironfounders exclusively for the mould. Burgie, the dust coal of the mines, and screenings from house coal, is in Wales and other parts pressed into cakes of artificial fuel. Wai'lich’s patent fuel consists of bricks made by compressing with an hydraulic press, dust of coal rendered coherent by bituminous matter, and partly charred. These bricks measure 9 by 6^ and 5 inches, are dense, and require breaking before using. They burn with but little smoke, and form an excellent fuel, particularly where economy of room is an object, as it can be stowed very compactly. In many collieries no important use has yet been made of the dust coal. By similar treatment every pound of it might be saved, with a good profit to the manufacturer. The ashes and small cinders sifted from the ash-pits and dust-holes are used for making bricks. Soot, again, is largely collected, and sold by the chimney-sweepers at 6c7. a bushel for transmission into the country as manure. Of argol, the sediment of wine vats and casks, we
