e North, their total value would have been
$6,189,713,551, and, deducting the present price, the _additional_ cash
value would have been $3,619,346,616. Now the whole number of slaves in
all the States, in 1860, was 3,950,531, multiplying which by $300, as
their average value, would make all the slaves in the Union worth
$1,185,159,300. Deduct this from the enhanced value of the farm lands of
the South as above, and the result would be $2,434,087,316 as the gain
in the price of farms by emancipation. This is independent of the
increased value of their unoccupied lands, and of their town and city
property.

By census tables of 1860, 33 and 36, the total value of the products of
agriculture, mines, and fisheries in the Free States was $4,100,000,000,
and of the Slave States $1,150,000,000, making the products of the Free
States in 1860 nearly 4 to 1 of the Slave States, and $216 _per capita_
for the Free States, and for the Slave States $94 _per capita_. This is
exclusive of commerce, which would greatly increase the ratio in favor
of the North, that of New York alone being nearly equal to that of all
the Slave States. Now, multiply the population of the Slave States by
the value of the products _per capita_ of the Free States, and the
result is $2,641,631,032, making, by emancipation, the increased annual
product of the Slave States $1,491,631,032, and in ten years, exclusive
of the yearly accumulations, $14,916,310,320.

By the table 35, census of 1860, the total value of all the property,
real and personal, of the Free States, was $10,852,081,681, and of the
Slave States, $5,225,307,034. Now, the product, in 1860, of the Free
States, being $4,100,000,000, the annual yield on the capital was 38 per
cent.; and, the product of the Slave States being $1,150,000,000, the
yield on the capital was 22 per cent. This was the gross product in both
cases. I have worked out these amazing results from the census tables,
to illustrate the fact, that the same law, by which slavery retarded the
progress of wealth in Virginia, as compared with New York, and of
Maryland and South Carolina, as compared with Massachusetts, rules the
relative advance in wealth of all the Slave States, as compared with
that of all the Free States. I have stated that the statistics of
commerce, omitted in these tables, would vastly increase the difference
in favor of the Free States, as compared with the Slave States, and of
New York as contrasted with Virg
