De Villefosse states, that in France bar-iron, made as it
usually is with charcoal, costs three times the price of the
cast-iron out of which it is made; whilst in England, where it is
usually made with coke, the cost is only twice the price of
cast-iron.

Chapter 19
On the Division of Labour
217. Perhaps the most important principle on which the
economy of a manufacture depends, is the division of labour
amongst the persons who perform the work. The first application
of this principle must have been made in a very early stage of
society, for it must soon have been apparent, that a larger
number of comforts and conveniences could be acquired by each
individual, if one man restricted his occupation to the art of
making bows, another to that of building houses, a third boats,
and so on.
