Charles Babbage,
On the Economy of Machinery and Manufactures
(1846)
“ If only a few pairs of cotton stockings should be required, it would be an absurd waste of time, and of capital, to construct a stocking-frame to weave them, when, for a few pence, four steel wires can be procured by which they may be knit. If, on the other hand, many thousand pairs were wanted, the time employed, and the expense incurred in constructing a stocking frame, would be more than repaid by the saving of time in making that large number of stockings. ”
