the importance of the division of the labor. He gave us an example of the
process by which pins were made in England. "One man draws out
the wire, another strengthens it, a third cuts it, a fourth points it, and a
fifth gives it a head. Just to make the head requires two or three different

operations, which in some factories are all performed by different people,
though in others the same man will sometimes perform two or three of
them. Ten men, Smith said, in this way, turned out twelve pounds
