For those, who use _anthracite coal_, that which is broken or screened, is best for grates, and the nut-coal, for small stoves. Three tons are sufficient, in the Middle States, and four tons in the Northern, to keep one fire through the Winter. That which is bright, hard, and clean, is best; and that which is soft, porous, and covered with damp dust, is poor. It will be well to provide two barrels of charcoal, for kindling, to every ton of anthracite coal. Grates, for _bituminous_ coal, should have a flue nearly as deep as the grate; and the bars should be round, and not close together. The better draught there is, the less coal-dust is made. Every grate should be furnished with a poker, shovel, tongs, blower, coal-scuttle, and holder for the blower. The latter may be made of woollen, covered with old silk, and hung near the fire. Coal-stoves should be carefully put up, as cracks, in the pipe, especially in sleeping rooms, are dangerous. _On Lights._ Lamps are better than candles, as they give a steadier light, and do not scatter grease, like tallow candles. The best oil, is clear, and nearly colorless. Winter-strained oil should be used in cold weather. Lard is a good substitute for oil, for astral and other large lamps. It is cheaper, burns clearer, and has a less disagreeable smell. It will not burn so well in small lamps, as in large ones. Melt it every morning, in an old pitcher, kept for the purpose. Oil, long kept, grows thick, and does not burn well. It is therefore best not to buy it in large quantities. It should never be left standing in lamps, for several days, as this spoils it, and often injures the lamps. Camphine is a kind of oil manufactured in New York, which does not smell disagreeably, nor make grease-spots, and gives a brighter light than the best oil. Cleanse the insides of lamps and oil-cans, with pearlash-water. Be careful to drain them well, and not to let any gilding, or bronze, be injured by the pearlash-water coming in contact with it. Put one tablespoonful of pearlash to one quart of water. The care of lamps requires so much attention and discretion, that many ladies choose to do this work, themselves, rather than trust it with domestics. To do it properly, provide the following things:--An old waiter, to hold all the articles used; a lamp-filler, with a spout, small at the end, and turned up to prevent oil from dripping; a ball of wickyarn, and a basket to hold it; a lamp-trimmer, made for the purpose, or a pair of _sharp_ scissors; a small soap-cup and soap; some pearlash, in a broad-mouthed bottle; and several soft cloths, to wash the articles, and towels, to wipe them. If every thing, after being used, is cleansed from oil, and then kept neatly, it will not be so unpleasant a task, as it usually is, to take care of lamps.
