Some also have so little idea of harmony of colour, that without strict supervision they would give every volume the coat of a harlequin. In a word, a first-rate bookbinder is nascitur non ƒit, and although the hints and instructions I have penned may not be sufficient to make a workman, I trust they will be found of some value to the skilled as well as to the less practised craftsman.

Blocking.—The growing demand for books that were at once cheap and pretty, became so strong, that mechanical appliances were invented to facilitate their ornamentation; and thus we have the introduction of the present blocking press.

I will not follow too closely the various improvements introduced at different periods, but roughly describe the blocking press, without which cheap bookbinding cannot be done at the present day.
