A plan of a stove designed for burning its own smoke, was communicated by Mrs. Rachel Smith to a periodical journal, which seems susceptible, by its simplicity of construction and soundness of principle, to be made effective for the object intended The stove is made exteriorly of the usual form, excepting that the fire part f is of greater length or height than is common, and the spaces under the hobs are made into reservoirs to receive the coals, as shown at c c, for supplying the fire. The hobs are upon hinges, and form lids, which shut down very closely, - if air tight, the better. The cheeks of the grate are open at the bottom, so that the coals lying upon the inclined planes of the reservoirs descend by their own weight, and occupy the lower part of the grate; and as the fuel is consumed, or raised by the poker, a fresh portion of coals enters from either or both of the reservoirs, and fills up the apace. In this manner the fuel is constantly supplied, occasioning little or no smoke.

The reservoirs should be of a capacity sufficient to bold enough coals for the day's consumption.
