A REMARKABLE FURNAGE.

A surprising account is givenof a $ arnaco constructed by an inventor to secure the perfect combustion of coal, and thus avoid the great loss of heat and waste of fuel resulting from the imperfection of the best ; methods hitherto employed. 'In a common cylinder stove, with afew kitchen shovels of coal' —so ran the. statement of an eye-witness of one of the exhibitions of this invention in Philadelphia—' a fire was lighted, which, in a few minutes, without ariifical draught, created a heat intense enough to inclfc east iron, Spiegel and manganese ore. These results are accomplished by so arranging the fire that two different currents of air of different temperatures pass, through separate paijts of the grate. A partial vaounm is created in the centre of feho grate, and a cyclone in the drum of tho stove, thus producing porfect combustion all over the surface of the coal. In fifteen seconds from the lighting of the.fire the drum is red hot. A few seconds more and a rapid vibration occurs in the drum, and is felt all over the room with startling effect. The cycjfmo in tho stove is raging in Ml force, the drum loses its heat, and it is discovered that the air ia down the chimney. Within four minutes from the time of lighting the materials above mentioned may be melted, and yet .the temperature of the room may be kept at a moderate heat. A 601b, charge of coal will last twenty-four hours so slew and complete is the combustion.
