Cement For Glass And Metal.

An excellent cement for uniting glass to metal is made as follows: - Pure gum arabic is soaked in a small quantity of water for 12 hours and will then be of about the consistency of molasses. Calomell (mer-curous chloride or subchloride of mercury) is then added in sufficient quantity to make a sticky mass, stiring well to get a thorough mixture. It will harden, after applying, in a few hours so only enough should be made than is required for immediate use.

Harness Dressing

Myrtle wax, 2 lbs; beeswax, 2 lbs; tallow, 2 lbs; lamp black, 1 oz; castor oil, 2 pints; neatsfoot oil, 1 gal. Mix well by aid of gentle heat, and always mix thoroughly before using. The harness should be well cleaned before applying any kind of dressing. It is best to wash the leather with soap suds, and then dry with a cloth, before using the dressing.

Ammonia Soap

A soap made as follows as a cloth cleaner or grease eradicator is recommended: - Mix together 50 c. c. oleic acid; 25 c. c. ether; 25 c. c. chloroform; 250 c. c. benzine; and 50 c. c. spirit ammonia, in the order given, with occasional shaking. If a white emulsion is preferred, the same or double the quantity of ammonia water, may be substituted for the spirit, the excels of alkili in this case being rather an advantage.
