Use green wood for logs, and mix green and dry wood for the fire; and then the wood-pile will last much longer. Walnut, maple, hickory, and oak wood are best; chestnut or hemlock is bad, because it snaps. Do not buy a load in which there are many crooked sticks. Learn how to measure and calculate the solid contents of a load, so as not to be cheated. A cord of wood should be equivalent to a pile eight feet long, four feet wide and four feet high; that is, it contains (8 X 4 X 4 = 128) one hundred and twenty-eight cubic or solid feet. A city "load" is usually one third of a cord. Have all your wood split and piled under cover for winter. Have the green wood logs in one pile, dry wood in another, oven wood in another, kindlings and chips in another, and a supply of charcoal to use for broiling and ironing in another place. Have a brick bin for ashes, and never allow them to be put in wood. When quitting fires at night, never leave a burning stick across the andirons, nor on its end, without quenching it. See that no fire adheres to the broom or brush, remove all articles from the fire, and have two pails filled with water in the kitchen where they will not freeze. STOVES AND GRATES. Rooms heated by stoves should always have some opening for the admission of fresh air, or they will be injurious to health. The dryness of the air, which they occasion, should be remedied by placing a vessel filled with water on the stove, otherwise, the lungs or eyes will be injured. A large number of plants in a room prevents this dryness of the air. Where stove-pipes pass through fire-boards, the hole in the wood should be much larger than the pipe, so that there may be no danger of the wood taking fire. The unsightly opening thus occasioned should be covered with tin. When pipes are carried through floors or partitions, they should always pass either through earthen crocks, or what are known as tin stove-pipe thimbles, which may be found in any stove store or tinsmith's. Lengthening a pipe will increase its draught. 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 woolen, 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. LIGHTS
