56 When boards are lined on one side only it is usual to turn half an inch of the paper over the square or cut edge, and the lined side must be placed next the book.

Many binders line the mill-board all over with paper before cutting; this may save time, but the edge of the board at the joint is liable to be abraised, and the resulting joint uneven.

The boards when lined should be laid about or stood up to dry, and when dry, cut to the proper and exact size for the book. As a fact, the black boards now sold are much too new or green to be used direct by the binder, they should be stocked for some months. The requisite width is obtained by extending the compass from the back of the book to the edge of the smallest bolt or fold in the foredge. It is advisable not to measure less than this point, but to leave a leaf or two in order to show that the book is not cut down. The compasses being fixed by means of the side screw, the boards are to be knocked up even, compassed up, and placed in the lying press, in which they are cut, using, as before, the "cut-against," and placing the runner exactly to the compass holes. When cut they are to be tested by turning one round and patting them together again; if they are the least out of truth it will be apparent at once. The head or top of the boards is next to be cut by placing a square against the back and marking the head or top with a bodkin or point of a knife. The boards being quite straight are again put into the press and cut, and when taken out should be again proved by reversing them as before, and if not true they must be recut. The length is now taken from the head of the book to the tail, and in this some judgment must be used. If the book has already been cut the measure must be somewhat larger than the book, allowing only such an amount of paper to be cut off as will make the edge smooth. If, however, the book is to
