An orange upon a Prussian-blue ground

—The dye is first given by Pru ian blue in the ordinary way, and then the following discharge is printed-on :— A caustic lye being prepared, of 1·086 specific gravity, di olve in a gallon of it 2 pounds of an not to, and thicken with 3 pounds and a quarter of gum. Two days after the impre ion of this paste, pa the goods through steam, and wash them in running water. With these two designs, the logwood and gall black, formerly described, may be a ociated, to produce a rich effect. To the preceding practical instructions for printing calicoes, silks, woollens, and mixed fabrics, made of the two latter, a few annotations may be added. When an uniform colour is to be applied to both sides of the cloth, the padding proce is employed; but, when only one side is to be thus coloured, diagonal lines are cut very closely to each other upon the cylinder, which transfer so much colour from the trough to the cloth pa ed under it as to make the surface appear uniformly stained. This proce is called mattage by the French. Mordants or topical dyes, to be applied in this way, should not be much thickened. The doubler is the piece of felt or blanket stuff placed between the cloth to be printed, and the block printing table, or the cylinders. It should be kept very clean; because, were it soiled with acetate of iron, it would spoil all the light shades made with acetate of alumina. Filters for the colour shop of a print house are best made of wool, formed into a substantial conical cap by felting. A filter ought to be set apart for each different dye stuff. When the goods after dyeing are washed, by being held by the selvage, dipped, and shaken in a stream of water, the proce is called giving a list by the French ( donner une lis ière ). The piece is transferred alternately from one hand to another.
