When starting the fire leave the damper open. As soon as it is burning well, close it so that the oven will be heated. Your stove should also have a damper in the pipe, to save the heat which would otherwise run up the chimney. If there is none, have one put in. There are also dampers or slides in front of the stove to control the amount of air going in. The housekeeper must learn how to manage her stove; she must get acquainted with it, for every stove has its own way. Draw a picture or plan of the stove that you know best. See if you can tell plainly how to build a fire in your stove. If you use natural gas or a kerosene stove tell how that should be managed. _Gas and Oil Stoves._ Cooking may be done on an iron stove with either coal or wood as fuel, or the stove may be planned for burning gas or kerosene. The coal fire must be fed several times a day with coal and the ashes must be removed to keep the fire burning clearly. Wood burns out quickly and must be replaced often. Both wood and coal stoves mean almost constant care for the housekeeper. Gas gives less trouble. It comes in pipes from outside the house. This means that somebody else--the gas company--provides the supply. You turn on the gas when you want to use it and turn it off, if you are wise and thoughtful, the moment it is not needed. The gas company measures the amount of gas that you use by its meter, and you pay for every bit that you burn or waste. The important thing, then, is to use as little gas as possible in order to pay for as little as possible. You would rather pay twenty-five cents for a thrift stamp, than for gas that had burned simply because you had forgotten to turn it off. Be sure that gas is turned completely off at all places and never have a low light burning, as the flame may be blown out and the unburned gas escape. This would be dangerous and might even kill persons in the house. The kerosene stove may be used instead of a gas stove in houses which are not piped for a gas supply. If wicks are used they must be carefully trimmed, so that they will be clean and even. A kerosene stove needs frequent cleaning. It should be kept free from dust and from drippings of oil. The Fireless Cooker When a Girl Scout gets to thinking about all the work to be done in a kitchen she will ask some very important questions. How much work is to be done? How long does it take to do it? Can time be saved by doing it in a better way? How can I save labor? Save time? Save money? The Girl Scout will find the answers one at a time, if she does her own work. And if you do your own work you will at once call for a fireless cooker. The name sounds impossible, for you have always cooked with a stove, and, of course, a fire. How can you cook without a fire?
