Calf books have generally a morocco lettering piece of a different colour to the calf on the back for the title. This is, however, optional, and may or may not be used, according to taste. Leather lettering pieces have a great tendency to peel off, especially if the book be exposed to a hot atmosphere, or if the paste has been badly made, so that it is perhaps better if the calf itself be lettered.

All such books should be lettered on their natural ground. For lettering pieces, take morocco of any colour, according to fancy, and having wetted it to facilitate the work, pare it down as thin and as evenly as possible. Cut it to size of the panel or space it is intended to fit. When cut truly, pare the edges all round, paste it well, put it on the place and rub well down.

A very good plan as a substitute for lettering pieces is to colour the calf either dark brown or black, thus saving the leather at the expense of a little more time. When the lettering
