We have now certain data from which to argue, and I will first
investigate the alleged homogeneity of the South. Conceding that every
citizen of the two classes of Virginia, etc., and Delaware, etc., in
1790, was indisputably the descendant of an English cavalier, and that
the increase of population found an outlet into the new Slave States,
how would the case stand?

In 1860 these States contained 8,712,840; by Table II we calculated they
should contain 8,006,467; so that even in this case there are some
700,000 foreigners. But a little more research shows that the case is
much more unfavorable.

Up to 1840, the Southern States not only could have furnished all the
settlers in the Slave States, but must have sent out colonists. In 1840,
they had 4,604,873 inhabitants; add to this the natural increase, 25.1
per cent. (1,155,823), and we have 5,760,696 native born, and 423,781
foreigners required make their total of 6,184,477 inhabitants.

But in the next decade, add to the 5,760,696 native born, their
percentage of increase 23.9 (1,376,806), and we have 7,137,502,
requiring 1,575,338 foreigners, _more than one sixth_, for their total
of 8,712,840 white inhabitants.

By no conceivable chance can more than five sixths of the population of
the South be descended from the English cavaliers.

But if we concede to every Virginian, not only his inherent gentility,
but his unswerving purpose never to emigrate out of slave territory, and
an intuitive presentiment which pointed out which were to be the slave
portions of adjacent Territories, by these same percent
