Many persons who burn anthracite coal in their chambers, have suffered great inconvenience from not knowing how to extinguish it before they go to bed. The process is very simple, and always successful. Lift off with the tongs any large coals that may lie on the top, and lay them on the iron hearth of the grate; they will make good cinders to bum next day in a close-stove or furnace. Then shut up the tongs, and with them make a hollow or deep cavity just in the centre of the fire, heaping up the coals like a hill on each side, and making the tongs go down to the bottom of the grate. If there are not many coals, you may do this with the poker. The fire will immediately begin to fade and deaden; and in less than ten minutes, it will be entirely out, without farther trouble; unless it has been very large, and then it may require a second stirring.
In the morning, let the grate be cleared entirely of all the cinders and ashes, and swept out clean with a brush. Cover the bottom of the grate with a sort of flooring of small fresh coal, before you put in the kindlings; otherwise, after the kindlings (wood or charcoal) are lighted, they will burn away immediately, and fall through the bottom bars of the grate, before they have had time to gnite the coal that has been laid above them; so that the grate will have to be again cleared out, fresh kindlings brought, and the fire built up anew, before it can possibly succeed.
The above way of extinguishing a coal-fire answers equally well for a close-stove or a furnace.
The heat of a grate may be considerably diminished by standing up the blower against it; the bottom of the blower resting on the hearth. To lessen the heat of a close-stove, leave open the large door of the stove. In the same manner diminish the heat of a furnace.
