(d) Take a piece of fresh lime, slake it by sprinkling it with water, then mix into a paste, which apply by means of a soft brush, brushing well into the interstices of the carving; next set by in a warm place till perfectly dry, after which take another soft brush and remove the lime. Should it still remain discoloured, repeat the process, but be careful neither to make it too wet nor too hot in drying off, or probably the article might come to pieces, being most likely glued or cemented together. If it would stand steeping in lime water for 24 hours, and afterwards boiling in strong alum water for about an hour and then dried, it would turn out white and clean. Rubbing with oxide of tin (putty powder) and a chamois leather, will restore a fine gloss afterwards.

(e) Well clean with spirits of wine, then mix some whiting with a little of the spirits, to form a paste, and well brush with it. It is best to use a rubber of soft leather where there are no delicate points; put a little soap on the leather, and dip into the paste and rub the ivory until you get a brilliant polish, finish off with a little dry whiting; the leather should be attached to flat wood surface, and rub briskly.

(f) When ivory ornaments get yellow or dusky-looking, wash them well in soap and water, with a small brush to clean the carvings, and place them while wet in full sunshine; wet them 2 or 3 times a day for several days, with soapy water, still keeping them in the sun; then wash them again, and they will be beautifully white.

(g) Rub with soda bicarbonate applied on a tooth-brush dipped in warm water.

Leather Goods.—(a) Carriage tops that have faded and become grey can be restored by washing with a solution composed of 4 oz. nut-galls, 1 oz. each of logwood, copperas, clean iron filings, and sumach berries; put all but the iron filings and copperas in 1 qt. best white wine vinegar, and heat nearly to boiling point; then add the copperas and iron filings; let stand for 24 hours, and strain off the liquid; apply with a sponge. This is equally good for restoring black cloths.

(b) Enamelled leather tops that have been soiled by dust and rain should be washed with soft water and Castile or crown soap. Apply the water with a sponge and then scrub with moderately stiff brush; cleanse with clean water and dry with a “shammy.” Never apply any kind of oil or top dressing without first cleaning the leather.

(c) Mouldy Leather.—Remove the surface mould with a dry cloth, and with another cloth apply pyroligneous acid.

(d) Russet Leather-covered Mountings.—Remove all stains and dirt by rubbing the leather with a cloth and a little oxalic acid, and restore the colour and finish by the use of salts of lemon (tartaric acid) applied with a woollen cloth. Rub the leather until a good polish is produced.

(e) Rubber-covered Mountings.—Rub the covered as well as the metallic parts with a “shammy” and a little tripoli, and finish with a clean woollen cloth.

(f) Chamois-leather.—Make a solution of weak soda and warm water, rub plenty of soft-soap into the leather, and allow it to remain in soak for 2 hours, then rub it well until it is quite clean. Afterwards rinse it well in a weak solution composed of warm water, soda, and yellow soap. If rinsed in water only, it becomes hard when dry, and unfit for use. The small quantity of soap left in the leather allows the finer particles of the leather to separate and become soft like silk. After rinsing, wring it well in a rough towel, and dry quickly; then pull it about and brush it well, and it will become softer and better than most new leathers.
