regions. The case of the West Indies lies at one extreme in a number of
respects. As witnessed by the changing racial composition of the popula-
tion,
the growth of the island colonies depended entirely on the growth of
slavery. This was a direct consequence of the sugar revolution that began
in Barbados in the 1640s and later spread to the other islands. Sugar
production for export to Europe was immensely profitable, and the intro-
duction of sugar in the West Indies produced an explosive increase in the
demand for labor to plant and harvest the cane. Yet sugar cultivation also
required very heavy and arduous labor, most efficiently done by groups of
workers organized into gangs. West Indian sugar plantations more than
any other preindustrial agricultural enterprise became factories set in the
fields, and English indentured servants soon learned to avoid the punish-
ing work of sugar cultivation in the tropics. At the same time, the sugar
revolution reduced the attractiveness of the islands to English immigrants
of modest means for another reason. The technology of sugar cultivation,
with very high fixed capital requirements for the machinery and structures
needed to grind the cane, boil the juice, and cure and pack the sugar for
shipment, resulted in great economies of scale, and in consequence small
farms could not compete with the vast plantations that swallowed up the
islands' fertile land. The West Indies quickly became known as a region
that offered no real economic opportunity for former indentured servants
or poor free settlers. In addition, the mixture of Europeans and Africans
from a number of very different disease environments soon created
a
deadly
epidemiological environment that rapidly made the West Indies notorious
as a place of widespread disease and extraordinarily high mortality, and
most Englishmen were reluctant to risk premature death in the islands'
harsh demographic regime. With a rising demand for labor and a declin-
ing supply of both indentured and free English immigrants able to choose
their colonial destinations, West Indian planters readily turned to the use
of workers who did not share this ability, and African slaves quickly came
to dominate the labor forces of the sugar islands. Throughout the colonial
period the black population of
the
West Indies suffered a substantial excess
of deaths over births, and the islands' slave populations grew over time
only as a result of massive continuing importations of Africans in every
decade.
Among the mainland colonies, the Lower South, particularly South
Carolina, most resembled the West Indies in its heavy reliance on slave
labor. Also as in the islands, the increase in the black share of the labor
force in South Carolina, and later Georgia, coincided with the rise of a
