It is not to be believed what the waste of fuel really is, in the various processes in which it is employed in the economy of human life; and in no case is this waste greater than in the domestic management of the Poor. Their fire-places are in general constructed upon the most wretched principles; and the fuel they consume in them, instead of heating their rooms, not unfrequently renders them really colder, and more uncomfortable, by causing strong currents of cold air to flow in from all the doors and windows to the chimney. This imperfection of their fire-places may be effectually remedied;--these currents of cold air prevented,--above half their fuel saved,--and their dwellings made infinitely more comfortable, merely by diminishing their fire-places, and the throats of their chimnies just above the mantle-piece; which may be done as a very every trifling expence, with a few bricks, or stones, and a little mortar, by the most ordinary bricklayer. And with regard to the expence of fuel for cooking, so simple a contrivance as an earthen pot, broad at top, for receiving a stew-pan, or kettle, and narrow at bottom, with holes through its sides near the bottom, for letting in air under a small circular iron grate, and other small holes near the top for letting out the smoke, may be introduced with great advantage. By making use of this little portable furnace, (which is equally well adapted to burn wood, or coals.)--one eighth part of the fuel will be sufficient for cooking, which would be required were the kettle to be boiled over an open fire.--To strengthen this portable furnace, it may be hooped with iron hoops, or bound round with strong iron wire:--but I forget that I am anticipating the subject of a future Essay. Much good may also be done to the Poor by teaching them how to prepare various kinds of cheap and wholesome food, and to render them savoury and palatable.--The art of cookery, notwithstanding its infinite importance to mankind, has hitherto been little studied; and among the more indigent classes of society, where it is most necessary to cultivate it, it seems to have been most neglected.--No present that could be made to a poor family could be of more essential service to them than a thin, light stew-pan, with its cover, made of wrought, or cast iron, and fitted to a portable furnace, or close fire-place, constructed to save fuel; with two or three approved receipts for making nourishing and savoury soups and broths at a small expence. Such a present might alone be sufficient to relieve a poor family from all their distresses, and make them permanently comfortable; for the expences of a poor family for food might, I am persuaded, in most cases be diminished ONE HALF by a proper attention to cookery, and to the economy of fuel; and the change in the circumstances of such a family, which would be produced by reducing their expenses for food to one half what it was before, is easier to be conceived than described.
