By first giving the wood an application of some kind of dye, say a yellow, and before it is quite dry, an application of another kind of dye, say a blue, different colors, such as green orange, purple black, or brown stains can be produced. By such process of mixing the dye liquor, all sorts of color combinations can be secured and very beautiful results obtained.-"Hobbies, London."
