The mean ratio Of increase for the whole period OF

abomnable traffic among the earliest acts OF her

the natural increase Of the capital unaffected by
any extraneous causes. That authorizes, as a
safe assumption that the future increase will not
exceed three per cent. per annun. AS our popu-

The total number of the annual increase Of both
descriptions is SO 600. The total expense OF
transporting that number to Africa, (supposing no
reduction Of present prices) would be one million
and forty thousand dollars, and the requisite
amount of tonnoge would be only 10000 tons of
shipping, about one ninth part of the mercantile
marine CT the United States. Upon the SUPPOSE
ton Of vassel's making two voyages in the year,

quantity would be still further reduced, by en-
