The great expense of turning the wheel appears to have arisen
from the person so occupied being unemployed during half his
time, whilst the pointer went to another manufactory
338. It appears from the analysis we have given of the art of
pinmaking, that it occupies rather more than seven hours and a
half of time, for ten different individuals working in succession
on the same material, to convert it into a pound of pins; and
that the total expense of their labour, each being paid in the
joint ratio of his skill and of the time he is employed, amounts
very nearly to 1s.
