of a more even hardness throughout by warming it, as in tempering steel; but the heat must not be nearly so great. Brass, heated to the blue heat of steel, is almost soft again. To soften brass, heat it nearly to a dull red and allow it to cool, or, if time is an object, it may be cooled by plunging into water. Drawing Temper from Brass..— Brass is rendered hard by hammering or rolling, therefore when a brass object requires to be tempered the material must be prepared before the article is shaped. Temper may be drawn from brass by heating it to a cherry red and then simply plunging it into water, the same as though steel were to be tempered. BREWING BEER.— Beer is produced by the alcoholic fermentation of a mixture of malted barley and hops. Barley is steeped in water to soften the husk and to make the grain ready for the sprouting process. The moist grains are set aside for about eight days during which time sprouting takes place. The grains are then dried and ground to a coarse powder. The powder is placed in a mash tub and live steam is applied to it. This converts the starch into maltose and other sugars. This liquid which is called wort is heated, for several hours and during this time hops are added. The hops give the beer its bitter taste. The solution is drawn off from the solid matter and cooled. Yeast is now added and the fermentation which begins almost immediately is allowed to continue for about 10 to 12 days depending upon the temperature. The beer is then aged for several months and finally the clear product is drawn off from the sediment and bottled. Remedies for Fetid Breath..— Fetid breath may be due to the expelled air (i. e., to disease of the respirational tract), to gases thrown off from the digestive tract, or to a diseased mouth. In the first two cases medication must be directed to the causative diseases, with the last, antisepsis principally and the neutralization of the saliva, also the removal of all residual food of dental caries.

Use as a gargle and mouth wash. IV.—Mix and dissolve. Use as gargle and mouth wash. V.—Mix. Gargle and wash mouth well with 10 drops in a glass of water. VI.—Mix. Use as a dentifrice. VII.—Mix. Gargle the mouth twice daily with 2 tablespoonfuls of the mixture in a glass of water. VIII.—Mix a half-teaspoonful in a wineglassful of water. Wash mouth two or three times daily. BRICK STAIN.— To stain brick flat the color of brownstone, add black to Venetian red until the desired shade is obtained. If color ground in oil is used, thin with turpentine, using a little japan as a drier. If necessary to get the desired shade add yellow ocher to the mixture of red and black. If the work is part old and part new, rub the wall down, using a brick
