all unevenness of the leather is to be pared away. This style has gained its reputation very much on account of its economy; the amount of leather required is less, and the work is as strong and serviceable as in a whole-bound book. It will be better if the back be finished before the corners are put on, as there is great likelihood that the corners may get damaged to some extent during the process of finishing.

CHAPTER XXI.
Pasting Down.
This is to cover up the inside board by pasting down the end papers to the boards.
The white or waste leaf, that has till this process protected the end papers, must now be taken away or torn out. The joint of the board must be cleaned of any paste or glue that may have accumulated there during the course of either gluing up or covering, by passing the point of a sharp knife along it, so that when the end is pasted down, the joint will be quite straight and perfectly square.

This thickness must be carefully chosen, and one edge be cut off straight, and fastened to the inside of the board very slightly, in fact only touching it in the centre with a little glue or paste, just sufficient to hold it temporarily. It must be
