one, yet the process doubles the return for each acre of fifty. The
man who needs a little fuel for his own use, expends much labour in
opening the neighbouring vein of coal; but to enlarge this, so as to
double the product, is a work of comparatively small labour. To sink a
shaft to the first vein below the surface, and erect a steam-engine,
are expensive operations; but these once accomplished, every future
step becomes more productive, while less costly. To sink to the next
vein below, and to tunnel to another, are trifles in comparison with
the first, yet each furnishes a return equally large. The first line
of railroad runs by houses and towns occupied by two or three hundred
thousand persons. Half a dozen little branches, costing together far
less labour than the first, bring into connection with it half a
million, or perhaps a million. The trade increases, and a second
track, a third, or a fourth, may be required. The original one
facilitates the passage of the materials and the removal of the
obstructions, and three new ones may now be made with less labour than
was at first required for a single one.

All labour thus expended in fashioning the great machine is but the
prelude to the application of further labour, with still increased
returns. With each such application, wages rise, and hence it is that
portions of the machine, as it exists, invariably exchange, when
brought to market, for far less labour than they have cost. There is
thus a steady decline of the value of capital in labour, and a daily
increase in the power of labour over capital, and with each step in
this direction man becomes more free. The man who cultivated the thin
soils was happy to obtain a hundred bushels for his year's work. With
the progress of himself and his neighbour down the hill into the more
fertile soils, wages have risen, and two hundred bushels are now
required. His farm will yield a thousand bushels; but it requires the
