Babbage, Charles, 1792-1871

"On the Economy of Machinery and Manufactures"

This is by no means
easy to effect, particularly amongst that class whose daily
labour procures for them their daily food. The system which has
long been pursued in working the Cornish mines, although not
exactly fulfilling these conditions, yet possesses advantages
which make it worthy of attention, as having nearly approached
towards them, and as tending to render fully effective the
faculties of all who are engaged in it. I am the more strongly
induced to place before the reader a short sketch of this system,
because its similarity to that which I shall afterwards recommend
for trial, will perhaps remove some objections to the latter, and
may also furnish some valuable hints for conducting any
experiment which might be undertaken.
307. In the mines of Cornwall, almost the whole of the
operations, both above and below ground, are contracted for. The
manner of making the contract is nearly as follows. At the end of
every two months, the work which it is proposed to carry on
during the next period is marked out. It is of three kinds. 1.
Tutwork, which consists in sinking shafts, driving levels, and
making excavations: this is paid for by the fathom in depth, or
in length, or by the cubic fathom.
