Rounding.

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
