(d) For the outside, a strongish solution of washing-soda, applied with piece of flannel. If you find the soda remove the varnish (as it does with some oil-varnishes), use soap-and-water, and then paraffin. When clean, rub with linseed-oil; spirits of wine removes the old resin at once, but sometimes takes the varnish with it. For the inside, get a handful of rice, steep in solution of sugar and water 5 minutes, strain off, and nearly dry the rice till just sticky. Put in at sound-holes and shake till tired. This will pick up all dirt, then turn out.
Violin Bows.—(a) Take a small piece of flannel, wet it (cold process), well rub it with best yellow soap, double it, holding the hair gently between the finger and thumb, rub gently till clean, using plenty of soap; rinse flannel, wipe off, then wipe dry with a piece of calico or linen; in an hour afterwards it will be ready for the resin. (b) A solution of borax-and-water.
Wall-papers.—To remove oil stains or marks where people have rested their heads, from wall-papers, mix pipeclay with water to the consistency of cream, lay it on the spot and allow it to remain till the following day, when it may be easily removed with a penknife or brush.
Watches.—A correspondent of the Watchmaker and Metal-worker tells how he cleans watches with benzine. The method may be useful for other fine work. He says: I immerse the parts in benzine and dry in boxwood sawdust. This gives the gilding a fresh, new look, which I have not been able to get by any other process. The movement must be entirely taken down. The dial screws may be screwed down tightly and left, but all parts united with screws must be separated, so that there will be no places where the benzine can remain and not be at once absorbed by the sawdust. I have a large alcohol cup, which I fill about half full of benzine, taking down my movement and putting the larger pieces in the fluid. The scape wheel, balance, and delicate parts I treat separately, that they may not be injured by contact with the heavier pieces. I then take the pieces one at a time, and tumble them into the sawdust. In a few seconds they will be dry, when I pick them out and lay in a tray, using brass tweezers, which do not scratch. I treat all the parts in this way except the mainspring, when a slight use of the brush and clean chamois will remove all dust. Of course, the holes must be cleaned with a pointed peg; and I wipe out the oil sinks with chamois over the end of a blunt peg, but it is not often necessary to clean the pinions with a peg; they will come out of the sawdust bright and clean. The mainspring must not be put in benzine unless you want it to break soon after. The fluid seems to remove the fine oily surface which a spring gets after working for a time, and which is very desirable to retain; so I clean my springs by wiping with soft tissue paper. If they are gummy, I put on a little fresh oil to soften, and wipe off, being careful not to straighten out the springs.
Vermin, Destroying
Vermin, Destroying.—Before proceeding to classify the various kinds of noxious creatures whose presence is objectionable to man, and giving hints for their destruction or removal, it will be well to put forward a word of caution against using any substance which will poison the vermin in situations where their bodies can putrefy unseen and produce unpleasant and injurious odours. Wherever poisons are mentioned in the following recipes their use is intended exclusively away from the dwelling, and there are many sound reasons why poisons should be avoided on all occasions.
Insects.—As this word is commonly used in the household it embraces a considerable number of small creatures outside the class known as insects to naturalists, and may be regarded as including all winged and creeping vermin.
Before descending to special remedies against different insects a few lines may be devoted to that universal insecticide the so-called “Persian insect powder.” This is of two kinds, one produced in the Transcaucasian region and another in Dalmatia. The first is the produce of Pyrethrum roseum and P. carneum, and the last of P. cinerariæfolium [Chrysanthemum turreanum], all common wild flowers in their special districts. The useful part of the plants is their flowers, which are gathered when half developed, in dry weather, dried in the shade under cover, ground to powder, and stored in air-tight vessels. The plants can be cultivated in warm climates. The Dalmatian gives the stronger powder, or perhaps the powder sold there is less adulterated. Experiments have conclusively proved that while these powders are perfectly harmless to human beings and domestic animals, they are distinctly poisonous to all insects having open mouth parts, such as bees, wasps, ants, mosquitoes, flies, fleas, bugs, dragon-flies, spiders, carpet-beetles, &c.
Ants.—(a) White ants will eat the whole timber work of a house without noise. They bore close to the surface of the wood, but without destroying it, so that there is no visible indication of what they are doing. They will even bore through the boards of a floor and up the legs of a table, leaving the latter a mere shell. The principal woods used in this country which are said to resist the white ant are cedar, greenheart, ebony, and lignum vitæ, and the heartwood of jarrah. Pitch pine is sometimes attacked. White ants will not attack new teak, but will bore through teak to get at yellow pine. Arsenic seems to prevent the attack of these insects, and is sometimes used for this purpose in the concrete, mortar, paint, and plaster of buildings. Arsenic is also mixed with aloes, soap, &c., to form a wash to exterminate these insects. Creosoting is an effectual preservative against white ants, but on account of its smell is only adapted for out-door work, and can hardly be applied to very dense tropical timbers. A cheap source of arsenic for this purpose is the lime arsenite residue from aniline dyeworks.
(b) Black Ants.—Scatter a few leaves of green wormwood about their haunts. (c) To clear them from pantries, chalk the shelves upon which the provisions are put, so that the ants cannot move about; or apply moistened fly-paper and lay about the pantry; or apply quassia tincture, and soak crumbs of bread with it, and lay it about the pantry. (d) Leave a vessel, such as a butter-crock, containing at the bottom a few stewed prunes, or a little water in which prunes have been stewed, uncovered in the places frequented by the ants; it will attract them, and thousands will drown in it. (e) Boil pieces of string in beer and sugar, and lay them in the ants’ way; collect once in 24 hours, when they will be found covered with ants, and drop into boiling water. (f) Pour benzoline down the holes. (g) Pour boiling water down the holes. (h) Rooms on a ground floor may be cleared by carefully pouring some strong oil of vitriol down each hole. This will be fatal to the living insects and all their eggs, but will destroy flooring, plaster, and bricks wherever it touches.
