dozen or more signatures, places each of these between smooth wooden boards, and puts the whole into an upright iron press, in which it is subjected to a great pressure, and where it ought to remain over night in order to make it entirely flat and solid. A better way of pressing a book at this stage of the operation is to pass it several times through a rolling machine, which is made for this special purpose with two heavy iron rollers, say twenty inches long and ten inches in diameter. These machines are seldom used in America, but are invariably found in the equipment of binders' workshops abroad, which is perhaps one reason why English books are so solidly bound. Following the pressing, or the rolling, the book is placed, back uppermost, in another press, something like a wooden vise. By means of a handsaw, several cuts, just deep enough to cut entirely through the fold of each signature, are made across the back of the book. Seven of these saw marks are usually made, the five in the middle being for the cords on which the book is sewed, and the two at the ends for threads which help to make the sewing more secure. If the book is to have a binding with raised bands across the back, no actual cuts are made, the back being simply scratched to guide the girl in sewing, so that the heavy twine on which she sews will stand out on the back, forcing the leather up in the five middle places and forming the raised bands. After it has been sawed, or scratched, the book goes to a girl who collates it--that is, examines it thoroughly, signature by signature, and makes sure that everything is in its right place. If the volume is old or especially valuable, it is gone over page by page. The first and last signatures are then whip-stitched, or sewed over and over along the back edges, and then put in their places. The book is then sewn on a "sewing frame." This is a small wooden table about twelve by eighteen inches, with legs only one inch high. At two corners there are upright wooden screws, some fifteen inches long with movable collars which support a crosspiece. To this crosspiece are fastened three stout cords, their other ends being attached to the table. The position of these cords are regulated to fit the saw marks on the back of the book, then they are tightened by means of the screw collars. The sections of the book are then placed against these cords, one by one, and the threads passed through the saw cuts and outs
