524 had no sticks. The peculiar workmanship of the unknown printer and of Albert Pfister shows that the types were taken direct from the case and wedged in the mortised blocks of wood which served for chases. Blades attributes the uneven spacing and irregular endings of lines in the early printed books of Caxton and of other printers, to their ignorance of the advantages of a composing rule, without which types could not be readily moved to and fro, and adjusted.

In the following illustration, the compositor has the copy before her in the shape of a book, but Conrad Zeltner, a learned printer of the seventeenth century, said that this was not the early usage; that it was customary to employ a reader to read aloud to the compositors, who set the types from dictation, not seeing the copy. He also says that the reader could dictate from as many different pages or copies to three or four compositors working together. When the compositors were educated, the method of dictation may have been practised with some success; when they were ignorant, it was sure to produce many errors. Zeltner said that he preferred the old method, but he admits that it had to be abandoned, on account of the increasing ignorance of the compositors.
