The oven is heated by a circulation of hot air. This is accomplished by closing the oven-damper, which is situated near the oven. When this damper is left open, the hot air rushes up the chimney. The damper near the chimney is known as the chimney-damper. When open it gives a free outlet for the escape of smoke and gas. When partially closed, as is usually the case in most ranges, except when the fire is started, it serves as a saver of heat. There is also a check, which, when open, cools the fire and saves heat, but should always be closed except when used for this purpose.
Stoves are but seldom used, portable ranges having taken their places.
A portable range is a cooking-stove with one oven door; it often has an under oven, of use for warming dishes and keeping food hot.
A set range is built in a fireplace. It usually has two ovens, one on each side of the fire-box, or two above it at the back. Set ranges, as they consume so large an amount of fuel, are being replaced by portable ones.
HOW TO BUILD A FIRE
Before starting to build a fire, free the grate from ashes. To do this, put on covers, close front and back dampers, and open oven-damper; turn grate, and ashes will fall into the ash receiver. If these rules are not followed, ashes will fly over the room. Turn grate back into place, remove the covers over fire-box, and cover grate with pieces of paper (twisted in centre and left loose at the ends). Cover paper with small sticks, or pieces of pine wood, being sure that the wood reaches the ends of fire-box, and so arranged that it will admit air. Over pine wood arrange hard wood; then sprinkle with two shovelfuls of coal. Put on covers, open closed dampers, strike a match,—sufficient friction is formed to burn the phosphorus, this in turn lights the sulphur, and the sulphur the wood,—then apply the lighted match under the grate, and you have a fire.
Now blacken the stove. Begin at front of range, and
