A BRANDING INK.—A waterproof branding ink, good for marking sheep: Shellac two ounces, Borax two ounces, Water twenty-four ounces, Gum Arabic two ounces, Lamp Black sufficient. Boil the Borax and Shellac in the water till they are dissolved, and withdraw them from the fire. When the solution becomes cold, complete 25 ounces with water, and add Lamp Black enough to bring the preparation to a suitable consistency. When it is to be used with a stencil it must be made thicker than when it is used with a brush. The above gives black ink. For red ink substitute Venetian Red for Lamp Black; for blue Ultramarine; and for green a mixture of Ultramarine and Chrome Yellow.
FRENCH POLISH, or DRESSING FOR LEATHER.—Mix two pints best Vinegar with one pint soft water. Stir into it one-fourth pound Glue, broken up, one-half pound Logwood chips, one-fourth ounce finely powdered Indigo, one-fourth ounce best soft Soap, and one-fourth Isinglass. Put the mixture over the fire, and let it boil ten minutes or more; then strain, bottle and cork. When cold it is fit for use. Apply with a sponge.
NEW YORK BARBER'S STAR HAIR OIL.—Castor Oil six and one-half pints, Alcohol one and one-half pints, Citronella and Lavender Oil, each one-half ounce.
BARBER'S SHAMPOOING MIXTURE.—Soft Water one pint, Sal Soda one ounce, Cream Tartar one-fourth ounce. Apply thoroughly to the hair.
CRUCIBLES.—The best crucibles are made of a pure fire clay, mixed with finely ground cement of oil crucibles, and a portion of black lead or graphite; some pounded coke may be mixed with the plumbago. The clay should be prepared in a similar way as for making pottery ware. The vessels, after being formed, must be slowly dried, and then properly baked in a kiln.
Black Lead Crucibles are made of two parts of Graphite and one of Fire Clay, mixed with Water into a paste, pressed in moulds, and well dried, but not baked hard in the kiln. This compound forms excellent small or portable furnaces.
WHAT TO INVENT, AND HOW TO PROTECT YOUR INVENTION.
WHAT TO INVENT.—Cheap, useful articles that will sell at sight. Something that everyone needs, and the poorest can afford. Invent simple things for the benefit of the masses, and your fortune is made. Some years back a one-armed soldier amassed a fortune from a single toy—a wooden ball attached to a rubber string. They cost scarcely anything, yet millions were sold at a good price. A German became enormously rich by patenting a simple wooden plug for beer barrels. "What man has done, man may do."
HOW TO PROTECT YOUR INVENTION.—Patent it. If you do not, others will reap the benefits that rightfully belong to you.
