128 with gold leaf, take one of the tools heated to such a degree that when a drop of water is applied it does not hiss but dries instantly; work it exactly in the blind impressions. Repeat this to the whole of the impressions, and wipe the overplus of gold off with the gold rag. The impressions are now supposed to be worked properly in gold; but if there are any parts where the gold does not adhere, they must be re-glaired and worked in again. A saucer should be placed near at hand, with water and a piece of rag or a sponge in it, to cool any tool and reduce it to its proper heat before using. If the tool be used too hot, the gold impression will be dull; if too cold, the gold will not adhere. To use all tools of the exact degree of heat required is one of the experiences of the skilled workman. The back is now ready for the title. Set up the proper words in a type-case, of a type sufficiently large and suitable to the book. The chief word of the title should be in somewhat larger size than the rest, the others diminishing, so that a pleasant arrangement of form be attained. In order to adjust the length of the words, it may be necessary to space some of them—that is, to put between each letter a small piece of metal called a space. Square the type, or make the face of the letters perfectly level, by pressing the face of them against a flat surface before tightening the screw. They must be exactly level one with another, or in the working some of them will be invisible. Screw up the type-case, warm it over the finishing stove, and work the letters carefully in blind as a guide. Damp the whole of the lettering space with vinegar. When dry, pencil the impressions in twice with glaire. Then lay the gold on and work them in gold.

But with lead type and a spring type-case (a method more suitable for some binders on account of its relative cheapness and the convenience of the case fitting itself to the different sizes of the type, of which the binder will want
