In the manufacture of colored paper, the bouquet marble is mostly produced from two or three browns and one black, and is often used for lining end papers in fine books. After the colors have been thrown on, drawn by the stylus and combed in the ordinary way, a rake-like wooden instrument is moved through the colors right and left across the whole surface of the size so that in moving the rake the teeth of the second row trace those of the first row precisely, and so on until the rake has been moved over the whole surface from the right end of the trough to the left. A somewhat changed design is produced by treatment of the colors in the same way leaving out the marbling comb and spreading the drops of color thrown on only by the aid of the stylus into very narrow cross-lines and then using the aforementioned rake as already explained. The rake consists of a piece of board of hard wood, of about 1 inch less in length, than the width of the trough, 1-1/4 inches wide and 1/2 inch thick, into which are inserted two rows of sharply pointed wooden teeth about 1 inch distant from each other and leaving a space of about 1 inch between the two rows, in such a way that the teeth of the second row are situated precisely between the teeth of the first row. ENTWINED COMB MARBLE. THE ENTWINED COMB MARBLE. (SEE SPECIMEN PLATES.) This comb-marble, produced by drawing the comb back, is a great favorite on account of its beautiful designs, but is more adapted for thicker books as on those only can the pattern be seen to full advantage. The production is entirely the same as that of comb marbles, but the teeth of the comb must be about 1/2 inch distant from each other and the comb must be 1/2 inch less in width than the trough so that it can be moved right and left at will, when the marble is drawn by this comb the latter is drawn back in such a way that the teeth cross the centre of the scales. THE SNAIL MARBLE. THE SNAIL MARBLE. (SEE SPECIMEN PLATES.) The production of this marble is very simple. The colors are thrown on as for comb-marble and are drawn by the stylus into wavy lines and then, one by one, by the aid of the stylus, snail forms are produced. THE GRAY SNAIL MARBLE. The manner of production is the same as that of the plain gray marble, with the exception that so much green is added till a desired tone is obtained. After this ground-color has been thrown on, the marble is drawn by the aid of the stylus into snails and then taken off. THE COMMON GREENISH-GRAY SNAIL MARBLE.
