Books which are to be left in a closed house should be carefully dusted and shut in cases, or covered with sheets. A piece of gum camphor, or a few drops of oil of lavender put on the shelves will help to keep away insects, mould and mustiness.
Leather-bound books need special care about once a year whether the house is open or closed. Care which agrees well with them is this: First wipe them thoroughly and affectionately with a flannel cloth; then dip a small piece of flannel into a mixture of equal parts paraffine and castor oil, and with it wipe all the leather parts of the bindings.
In city houses green shades are usually put up in summer and light-coloured ones in winter. Any shade which is taken down should be tightly rolled to keep the spring from loosening.
When closing a house in a place where there is much dust, it is well to lay pieces of paper on the window sills, just far enough over the outer edge to be held by the window when it is shut. These keep the dust which sifts in from lying on and discolouring the sills. If stoves, lengths of pipe and wire screens are put away for a time, it is well to grease them, unless the place where they are put is absolutely dry. Melted lard or drippings are good for this purpose, and also kerosene, though in time this completely evaporates. The nickel parts of stoves keep in better condition if they are wrapped in paper after they are greased.
When a kitchen is to be closed for a season, the room and everything in it must be left clean and dry, otherwise there will be mould, rust and water-bugs to contend with when the house is opened. Some scouring and polishing will be saved if bright tin and brass utensils and fittings are wrapped in paper. The contents of cupboards and drawers should be grouped on tables and covered with paper or cloths, and no food kept except stores which are not injured by keeping.
Inflammable liquids such as alcohol, kerosene and turpentine should not be left in a closed house. Matches should be shut in a tin box or taken away altogether.
The last thing before a house is closed--gas, electricity and water must be turned off. After the water is turned off, empty the tanks of the closets as they may rust if water stands in them several months. Crude glycerine or some liquid which does not evaporate should be poured into all traps. In the course of months the water in traps evaporates and leaves the passageway for gases from the sewer to the house unobstructed.
