The manner in whicli these metal plates are disposed of forms the general system. The grates, metal plates, or perforated funnels ought always to be so placed as to receive the greatest possible heat of the fire so as to become red hot; this is the essential point. 5 \ The smoke escaping from the fuel passes through a first metal plate or perforated funnel, and from thence is concentrated in a space which I call the smoke box; this is repeated between each grating. The smoke so concentrated coming in contact with these red hot metal plates burns of itself before arriving at the passage of the chimney, or does not 10 show itself at all, except as a'vapour; in this is all the system. In all cases a passage in the chimney is necessary; it is placed in the middle or at one end of the room, according to circumstances, and the exigencies of drawing the fire, sometimes, and particularly for sitting room chimneys, a current of air may be established to assist the fire drawing. 16 The metal plates and the smoke boxes are of different shapes and names, such for instance, as in certain cases the metal plates can be called '^chimney gratings,’Vchimney pipes, or funnels, and as regards their shape it is the same for long rooms when they can be called smoke tubes or strainers. This of course depends exclusively 20 on the form which they take, according to the situation or the sort of hearth where this system is to be used, and their size and number is determined by the same circumstances. The metal plates, gratings, funnels, and smoke boxes may be made of cast iron, steel, copper, or even cement. • 26 The result which proceeds from the disposition of the smoke boxes and the gratings is a concentration of immense heat around the hearth, which as it cannot escape directly by the chimney is followed by a real economy of fuel and a very great increase of heat. From what has been already said above, this system of utilising the 30 smoke has the advantage of not dirtying the chimney, so that it is impossible it can catch fire. This system can be adapted to chimneys actually in use. . .
