Rosewood Stain. In 3 pints of water boil $1/2$ pound of logwood until the decoction is of a dark red color, then add $1/2$ ounce of salts of tartar. The wood is to receive three or four coats of this liquid, which must be used whilst boiling hot, each coat being allowed to dry' thoroughly before another is applied. Veins may be formed in this with the black stain, using grainers' combs or other implements, but if this is done, the work is removed from mere staining and becomes an imitation of graining. Immerse $1/4$ pound red sandalwood and $1/2$ pound of potash in 1 gallon of hot water. When the color of the wood is extracted, $2 1/2$ pounds of gum shellac are to be added, and dissolved over a quick fire. The mixture may then be used over the stain above described.

Red Sandalwood. This dye-wood is the produce of a large tree growing to the height of sixty or seventy feet on the mountains and other parts of India. It is usually imported in small billets two or three feet in length, of a fine deep red color, the concentric circles of the transverse section being divided by dark, almost black, lines, with different mordants it yields brownish red, scarlet red, deep crimson, and yellowish red. These colors are not, however, very permanent. Another dye-wood, also called red sandalwood, the native name of which is Rutka-chundun, is the production of the largest trees of India. Neither of these must be confounded with the sweet-scented sandalwoods which are furniture woods.

Black Stains. To 6 quarts of water add 1 pound of logwood and two or three handfuls of fresh walnut peelings. Let the whole boil well until reduced to about half the quantity of liquid, then strain and add a pint of best vinegar, boil again, and apply the stain whilst quite hot. Dissolve 1 ounce of green copperas in a quart of water, and apply this whilst quite hot over the previous stain, which
