To Keep Milk from Turning Sour.—Add a little sub-carbonate of soda, or of potash. This by combining with, and neutralizing the acetic acid formed, has the desired effect, and keeps the milk from turning sooner than it otherwise would. The addition is perfectly harmless, and does not injure the taste.
Strawberry Vinegar.—Put four pounds of very ripe strawberries, nicely dressed, into three quarts of the best vinegar, and let them stand three or four days; then drain the vinegar through a jelly-bag, and pour it on the same quantity of fruit. Repeat the process in three days for a third time. Finally, to each pound of the liquor thus obtained, add one pound of fine sugar. Bottle, and let it stand covered, but not tightly corked, one week; then cork it tight, and set it in a cool, dry place, where it will not freeze. Raspberry vinegar is made the same way.
Cider Vinegar.—After cider has become too sour for use, set it in a warm place, put to it occasionally the rinsings of the sugar basin or molasses jug, and any remains of ale or cold tea; let it remain with the bung open, and you will soon have the best of vinegar.
To Give Luster to Silver.—Dissolve a quantity of alum in water, so as to make a pretty strong brine, and skim it carefully; then add some soap to it, and dip a linen rag in it, and rub over the silver.
To Make Water-Proof Porous Cloth.—Close water-proof cloth fabrics, such as glazed oil-cloth, India-rubber, and gutta-percha cloth are completely water-proof, but do not permit perspiration and the exhaled gases from the skin to pass through them, because they are air-tight as well as water-tight. Persons who wear air-tight garments soon become faint, if they are undergoing severe exercise, such as that to which soldiers are exposed when on march. A porous, water-proof cloth, therefore, is the best for outer garments during wet weather, for those whose duties or labor causes them to perspire freely. The best way for preparing such cloth is by the following process: Take 2¼ pounds of alum and dissolve this in 10 gallons of boiling water; then in a separate vessel dissolve the same quantity of sugar of lead in 10 gallons of water, and mix the two solutions. The cloth is now well handled in this liquid, until every part of it is penetrated; then it is squeezed and dried in the air, or in a warm apartment, then washed in cold water and dried again, when it is fit for use. If necessary, the cloth may be dipped in the liquid and dried twice before being washed. The liquor appears curdled, when the alum and lead solutions are mixed together. This is the result of double decomposition, the sulphate of lead, which is an insoluble salt, being formed. The sulphate of lead is taken up in the pores of the cloth, and it is unaffected by rains or moisture, and yet it does not render the cloth air-tight. Such cloth is also partially non-inflammable. A solution of alum itself will render cloth, prepared as described, partially water-proof, but it is not so good as the sulphate of lead. Such cloth—cotton or woolen—sheds rain like the feathers on the back of a duck.
To Cleanse Carpet.—1 teaspoonful liquid ammonia in one gallon warm water, will often restore the color of carpets, even if produced by acid or alkali. If a ceiling has been whitewashed with the carpet down, and a few drops are visible, this will remove it. Or, after the carpet is well beaten and brushed, scour with ox gall, which will not only extract grease but freshen the colors—1 pint of gall in 3 gallons of warm water, will do a large carpet. Table floor-cloths may be thus washed. The suds left from a wash where ammonia is used, even if almost cold, cleanses these floor-cloths well.
To Keep Hams.—After the meat has been well cured by pickle and smoke, take some clean ashes from bits of coal; moisten them with a little water so that they will form a paste, or else just wet the hams a little, and rub on the dry ashes. Rubbed in thoroughly they serve as a capital insect protector, and the hams can be hung up in the smoke-house or wood-chamber without any danger of molestation.
A Cold Cement for Mending Earthenware, says a recent English work, reckoned a great secret among workmen, is made by grating a pound of old cheese, with a bread grater, into a quart of milk, in which it must be left for a period of fourteen hours. It should be stirred quite often. A pound of unslaked lime, finely pulverized in a mortar, is then added, and the whole is thoroughly mixed by beating. This done, the whites of 25 eggs are incorporated with the rest, and the whole is ready for use. There is another cement for the same purpose which is used hot. It is made of resin, beeswax, brick-dust, and chalk boiled together. The substances to be cemented must be heated, and when the surfaces are coated with cement, they must be rubbed hard upon each other, as in making a glue-joint with wood.
How to Make Cucumber Vines Bear Five Crops.—When a cucumber is taken from the vine let it be cut with a knife, leaving about the eighth of an inch of the cucumber on the stem, then slit the stem with a knife from the end to the vine, leaving a small portion of the cucumber on each division, and on each separate slit there will be a new cucumber as large as the first.
White Cement.—Take white (fish) glue, 1 lb. 10 oz.; dry white lead, 6 oz.; soft water, 3 pts.; alcohol, 1 pt.
