The incinerators are made in various sizes, burn from one bushel of waste and upwards, depending on the whys and wherefores of its uses--whether it is the installed type, or the stove type, or for what home or institution it is designed. The stove types are purchasable in sizes ranging from 15 inches (wide) 15 inches deep and 30 inches high, to respectively 31 × 34 × 64 inches, and they range in price from about $70. and upward. (It isn’t safe, of course, to give prices to-day on anything as they change continually.) CASING They are usually built of very heavy serviceable castings, brass and sheet steel, well lined and insulated. Everything is well hinged and the grates, which are removable, are made so as to be easily taken out when it is necessary to remove the ashes or substances not burnable except in smelters. SUMMARY So almost in conclusion the incinerator is sanitary, destroys refuse, destroys it by burning not only the garbage but the products of the garbage combustion at a minimum expense, and it should sterilize itself and the flue in the process. And it does away forever with the back bending disposal of garbage into low cans for the openings into which the garbage is put are high and comforting. However, with all this we must not forget that garbage, if it can be expeditiously taken off the premises at once and easily, is an immense help as fertilizer and food for pigs. But it must have fine and careful care. The pits into which it is put must also have careful structure and care. To the surburbanite the incinerator will be a boon--no more fussing about garbage disposal and about who is going to collect it. And to apartment dwellers (and they are being put in apartments rapidly) no more elevator and dumbwaiter garbage and all the rest of the garbage nuisance. And to the new home builder, a sense of the disposal not only of garbage but of a vexing sanitary problem. Furthermore, because you have an incinerator, it doesn’t mean that you should burn up good left overs. Never burn up to-day what you can use on the morrow, and with this injunction we think you will enjoy looking into the subject of the disposal of waste. CHAPTER XIV AIR AND ITS ENTRANCE AND EXIT “Am I an _airess_?” not _heiress_, ought to be the question to ask yourself if you are really a responsible home manager. It seems strange that with all the air to be had for the asking you let it pass you by, content with whatever draughts and gusts filter through the cracks and crevices of your house. Now it so happens that although air is to be had for the asking, you have to woo it if you want it. But it pays. Keep the air about you in good condition and you and all those of your household will soon find yourselves approaching the 100% efficiency ideal.
