But all books are not glued up in the press; some workmen knock up a number of books, and, allowing them to project a little over their press, glue the lot up at once; others again, by holding the book in the left hand and drawing the brush up and down the back. These last methods are, however, only practised in cloth shops, where books are bound or cased at very low prices. The proper way, as I have explained, is to put the book in the lying press. The book is then laid on its side to dry, and if more than one, they should be laid alternately back and foredge, with the back projecting about half an inch, and allowed to dry spontanenusly, and on no account to be dried by the heat of a fire. All artificial heat in drying in any process of bookbinding is injurious to the work.

In rounding the back, the book is to be laid on the press before the workman with the foredge towards him; the book is then to be held with the left hand by placing the thumb on the foredge and fingers on the top of the book pointing towards the back, so that by drawing the fingers towards the thumb, or by pressing fingers and thumb together, the back is drawn towards the workman at an angle. In this position the back is struck with the face of the hammer, beginning in the centre, still drawing the back over with the left hand. The book is then to be turned over, and the other side treated in the same way, and continually
