111. _To make Imitation Rosewood._--Brush the wood over with a strong decoction of logwood, while hot; repeat this process three or four times; put a quantity of iron-filings amongst vinegar; then with a flat open brush, made with a piece of cane, bruised at the end, or split with a knife, apply the solution of iron-filings and vinegar to the wood in such a manner as to produce the fibres of the wood required. After it is dry, the wood must be polished with turpentine and bees'-wax. 112. _Imitation of Ebony._--Pale-colored woods are stained in imitation of ebony by washing them with, or steeping them in a strong decoction of logwood or galls, allowing them to dry, and then washing them over with a solution of the sulphate or acetate of iron. When dry, they are washed with clean water, and the process repeated, if required. They are, lastly, polished or varnished. 113. _Cheap Coloring for Rooms._--Boil any quantity of potatoes, bruise them, and pour on them boiling water until a pretty thick mixture is obtained, which is to be passed through a sieve; then mix whiting with boiling water, and add it to the potato mixture. To color it, add either of the ochres, lampblack, &c. 114. _Cheap Paint._--Tar mixed with yellow ochre makes an excellent green paint, for coarse wood-work, iron fencing, &c. 115. _Weather-proof Composition._--Mix a quantity of sand with double the quantity of wood ashes, well sifted, and three times as much slaked lime; grind these with linseed oil, and use the composition as paint; the first coat thin, the second thick; and in a short time it will become so hard as to resist weather and time. Or, slake lime in tar, and into it dip sheets of the thickest brown paper, to be laid on in the manner of slating. 116. _Artificial Marble._--Soak in a solution of alum a quantity of plaster of Paris. Bake it in an oven, and grind it to a powder. When wanted, mix it with water to about the consistency of plaster. It sets into an exceedingly hard composition, and takes a high polish. It may be mixed with various colored minerals or ochres to represent the various marbles, and is a valuable receipt. 117. _To give Wooden Stairs the Appearance of Stone._--Paint the stairs, step, by step, with white paint, mixed with strong drying oil. Strew it thick with silver sand. It ought to be thoroughly dry next morning, when the loose sand is to be swept off. The painting and sanding is to be repeated, and when dry, the surface is to be done over with pipe-clay, whiting, and water; which may be boiled in an old saucepan, and laid on with a bit of flannel, not too thick, otherwise it will be apt to scale off. A penny cake of pipe-clay, which must be scraped, is the common proportion to half a lump of whiting. The pipe-clay and whiting is generally applied once a week, but that might be done only as occasion requires.
