Here we see factors reflecting the growth of the company between 1855 and 1877.  Because all the typesetting was done manually the number of compositors seems to have grown in parallel with the number of printers. Only the lithography department seems to have maintained almost the same level of staffing over the 22 years.

Notably in the new building the firm upgraded its steam engine to 15 horsepower. They reduced the number of hand presses from 21 to 16, increased the number of steam-driven printing machines from 12 to 18. They also added to their very modest number of machines used in bookbinding.
