cannot be doubted that a larger portion of the thousands then annually
exported would have been sent in this direction.

Under these circumstances, the only mode of arriving at the history of
slavery prior to the first census, in 1790, appears to be to commence
at that date and go forward, and afterwards employ the information so
obtained in endeavouring to elucidate the operations of the previous
period.

The number of negroes, free and enslaved, at
that date, was.................................... 757,263
And at the second census, in 1801, it was......... 1,001,436

showing an increase of almost thirty-three per cent.
How much of this, however, was due to importation,
we have now to inquire. The only two States that
then tolerated the import of slaves were South
Carolina and Georgia, the joint black population
of which, in 1790, was............................. 136,358
whereas, in 1800, it had risen to.................. 205,555

In the same period the white population increased
104,762, requiring an immigration from the Northern
slave States to the extent of not less than 45,000,

natural increase by births. Admitting, now, that for
