RUST.—The preservation of iron and steel from rust is a very important consideration in domestic economy. The following plan of doing this is very little known, and is far superior to any other:—Add to a quart of cold water half a pound of quick-lime; let this stand until the top is perfectly clear; pour off the clear liquid, and stir up with it a quantity of olive oil, until the mixture becomes a thick cream, or rather assumes the consistence of butter which has been melted for the table, and has become cold. Rub the iron or steel which is to be put by with this mixture, and then wrap it up in paper. Knives and other steel articles treated in this way will not acquire the slightest rust. If the nature of the articles will not admit of their being wrapped up in paper, they will remain free from rust by covering them more thickly with the mixture. TO PRESERVE STEEL PENS FROM CORROSION.—Dip them for a few moments in ethereal solution of gold. This covers them with a film of pure metallic gold, which prevents the ink acting upon the steel. TO SOFTEN OLD PUTTY.—In removing old or broken panes from a window, it is generally very difficult to get off the hard dry putty that sticks round the glass and its frame. Dip a small brush in a little nitric or muriatic acid (to be obtained at the druggist’s), and go over the putty with it. Let it rest a while, and it will soon become so soft that you can remove it with ease. I have found this plan very successful.—H. B. TO REMOVE THE SMELL OF PAINT.—Take three or four broad tubs (such, for instance, as hold about eight gallons), fill them with cold water, and put into each an ounce of vitriolic acid, which you can obtain from a druggist. Place these tubs near the wainscot, in a newly painted room. This water will absorb and retain the effluvium of the paint. Next day fill the tubs with fresh water, and add to each another ounce of vitriolic acid. Repeat this a third day, and on the fourth the smell of the paint will not be perceptible. AN EXCELLENT PEN WIPER.—Procure two-pennyworth of small shot, (the smaller the better,) put them into a phial with the neck broken off; every time you wish to clean your pen, rub it up and down two or three times in the shot. This will clean it directly, and the shots will last a lifetime. The simple plan here suggested cleans steel pens ten times better than cloth wipers do: I have tested its utility very frequently.—C.
