If paper is to be used, the wall must be washed with clean water, as above explained; and while wet, the old color must be scraped off with a knife, or a smooth-edged steel scraper of any sort. It will be best to wet a yard or two at a time, and then scrape. Next, wash the wall all over with size, made with an ounce of glue to a gallon of water; and when this is dry, the wall is ready for the paper. This must be cut into lengths according to the different parts of the room; one edge of the plain strip must be cut off close to the pattern, and the other left half an inch wide. If the paper is thick, it should lie a minute or two after it is pasted; but if thin, the sooner it is on the wall, the better. Begin by placing the close-cut edge of the paper at one side of the window, stick it securely to meet the ceiling, let it hang straight, and then press it down lightly and regularly with a clean cloth. The close-cut edge of the next length will cover the half-inch left on the first one, and so make a neat join; and in this way you may go all round the room, and finish at the other side of the window. 22. _Damp Walls._--Damp may be prevented from exuding from walls by first drying them thoroughly, and then covering them with the following mixture: In a quart of linseed oil, boil three ounces of litharge, and four ounces of resin. Apply this in successive coats, and it will form a hard varnish on the wall after the fifth coating. 23. _To clean Moreen Curtains._--Having removed the dust and clinging dirt as much as possible with a brush, lay the curtain on a large table, sprinkle on it a little bran, and rub it round with a piece of clean flannel; when the bran and flannel become soiled, use fresh, and continue rubbing till the moreen looks bright, which it will do in a short time. 24. _To clean Calico Furniture._--Shake off the loose dust; then lightly brush with a small, long-haired furniture-brush; after which wipe it closely with clean flannels, and rub it with dry bread. If properly done, the curtains will look nearly as well as at first; and, if the color be not light, they will not require washing for years. Fold in large parcels, and put carefully by. While the furniture remains up, it should be preserved from the sun and air as much as possible, which injure delicate colors; and the dust may be blown off with bellows. By the above mode curtains may be kept clean, even to use with the linings newly dipped. 25. _Making Beds._--Close or press bedsteads are ill adapted for young persons or invalids; when their use is unavoidable, the bed-clothes should be displaced every morning, and left for a short time before they are shut up. The windows of bed-rooms should be kept open for some hours every day, to carry off the effluvia from the bed-clothes; the bed should also be shaken up, and the clothes spread about, in which state the longer they remain, the better.
