What sort of description does Penelope Fitzgerald provide of Tvyordov, the chief compositor?

The author affords a full description of Tvyordov, the chief compositor, and his work habits. The quality of his work at hand-setting type brings him much respect. Tvyordov's reputation likely is responsible for some part of the success Reid Press enjoys. Fellow workers are in awe of Tvyordov and the manner in which he meticulously accomplishes everything on a precise schedule. He arrives for work at the exact same time each day. Tvyordov determines how many seconds it takes to set his initial few lines. He then sets his daily goal from that point. Daily, at three minutes before ten he takes his break, and he winds the office clock each week.
