to dry. The remainder of the color on the size is skimmed, and the operation repeated as above described. The fore edges are marbled before the heads and tails are trimmed. After the books are rounded, proceed with the heads and tails in the same manner as with the fore edges. To avoid getting a portion of the color on the fore edges, dip a sponge into the size and apply it to the comer of the fore edges, which will be dipped in the size. If air bubbles should appear, dry the spot and redip immediately. The color will only bind to the dry spot.

Snail Marble. — The colors are thrown on as in comb edges, and drawn into wavy lines by the stylus, after which the snails are produced one at a time by dipping the stylus into the size at regular intervals, twisting it to the right and forming scrolls. The comb may also be drawn through the color and snails produced as above described.

American Marble. — This marble is made exactly as the comb, with the additional drawing of the comb the width of the trough.

Peacock Marble. — The method of preparation is the same as that for the comb, except that after the colors

have been drawn by the stylus into wavy lines, they are alternately drawn wide and narrow by the peacock comb. Draw the comb for about 1 inch, then close it, then draw for another inch, and open.

Bouquet Marble. — Proceed as for the comb marble. Draw a fine comb through the colors, and use the rake in such a way that the teeth of the second row will trace those of the first. Repeat this operation by moving the rake from right to left. The sliding or peacock comb may be substituted for the rake with equally good results.

SUN SPOTS.

The sun spot can be produced on any Turkish, snail, or wave marble by sprinkling the preparation after the ground colors have been thrown on. To prepare this, add a few drops of kreolin chalk water to a small quantity of color. Boil a little potash in one-half pint of water and add to the color and chalk water. To test the strength, try the color and chalk by sprinkling on the size. The chalk water will spread the color according to the strength, and this can be regulated as desired. Then add a little of the potash, which has been dissolved in water; this will draw the color together in the center of the spot. The reward for patiently trying out the different strengths of the preparation will be ample in the production of beautiful edges.

Sprinkle a few drops upon the size, and the sun rays will appear. These will spread out until the expansive force is expended; then diminish in size, and gradually vanish. If a second drop is put exactly upon the first, the rays will be more vivid. If two colors are prepared with this preparation and thrown one on the other, a still more beautiful effect is obtained.
