piece of paper put close to the head-band to prevent any paste soiling the edge or head-band, and with the boards extended, the hollow is pulled a little away from the back and the leather neatly tucked in. The leather is next to be tightly brought over the boards and well rubbed down, both on the edge and inside, with a folding stick, but on no account must the outside be rubbed, or the grain will be taken away. The foredge is to be treated in like manner, by tucking the corners in for strength. The head-band is now to be set, by tying a piece of thread round the book between the back and the boards in the slots cut out from the corners of the boards; this thread must be tied in a knot. The book being held in the left hand, resting on its end, the leather is drawn with a pointed folding-stick, as it were, towards the foredge, and flattened on the top of the head-band. When this is done properly it should be exactly even with the boards, and yet cover the head-band, leaving that part of the head-band at right angles with the edge exposed. With a little practice the novice may be able to ascertain what amount of leather is to be left out from the turning-in, so that the head-band can be neatly covered. The perfection in covering a book depends upon the leather being worked sharp round the boards, but with the grain almost untouched.

Paste should be always used for morocco, calf, russia and vellum, in fact for all kinds of leather; but in my humble opinion, all leather with an artificial grain should be glued; the turning-in may be with paste. The glue gives more
