Howard, a pioneer of the Di.slrict, has been quietly at work on the most needed improvement in milling, the de.sulpburizing and chloridizing of silver ores, He claim.' for his furnace a saving of four fifths in the labor, and fully one-faaif in the fuel here- tofore required, besides eliecting the most thorough roasting pos.sible ; also, reipiiring le.ss time for a given quantity of pulp. For this reason his furnace is self-acting throughout, and perpetual in its operation, no time being lust in discharging or refil¬ ling. The pulp enters at the point of ex¬ panded heat, anil is carried gradually around and discharged at the most intense. The arrangement is such that, by shifting the angle of the hoes, any desired length of exposure is given to the pulp between its entrance and its discharge. There is no. thing destructible about the furnace that is exposed to the direct action of the heat, ex- cept the hoes, which may be replaced in a few minutes’ time, at a trifling cost, and in that respect the wear is no greater than in the old reverberatory furnace, on the same quantity of ore roasted. This invention should not be confounded or classed with the numerous rotary and other labor- SEWELL AND CAMEKON’S VLKliCAL STEAM PUMP. saving furnaces of late invention, some of which are proportion of five ounces per t^n.
