emen are alarmed _lest the markets of other states be closed
against the introduction of our slaves_. Sir, the demand for slave
labor MUST INCREASE through the South and West. It has been heretofore
limited by the want of capital; but when emigrants shall be relieved
from their embarrassments, contracted by the purchase of their lands,
the annual profits of their estates, will constitute an accumulating
capital, which they will _seek to invest in labor_. That the demand
for labor must increase in proportion to the increase of capital, is
one of the demonstrations of political economists; and I confess, that
for the removal of slavery from Virginia, I look to the efficacy of
that principle; together with the circumstance that our southern
brethren are constrained to continue planters, by their position, soil
and climate."

Md. vol. 35, p. 4.

_"Dealing in slaves has become a large business_; establishments are
made in several places in Maryland and Virginia, at which they are
sold like cattle; these places of deposit are strongly built, and well
supplied with thumb-screws and gags, and ornamented with cow-skins and
other whips oftentimes bloody."

R.S. FINLEY, Esq., late General Agent of the American Colonization
Society, at a meeting in New York, 27th Feb. 1833, said:

"In Virginia and other grain-growing slave states, the blacks do not
support themselves, and the only profit their masters derive from them
is, repulsive as the idea may justly seem, in breeding them, like
other live stock for the more southern states."

Rev. Dr. GRAHAM, of Fayetteville, N.C. at a Colonization Meeting,
held in that place in the fall of 1837 said:

"He had resided for 15 years in one of the largest slaveholding
counties in the state, had long and anxiously considered the subject,
and still it was dark. There were nearly 7000 slaves offered in New
Orleans market last winter. From Virginia alone 6000 were annually
sent to the south; and from Virginia and N.C. there had gone, in the
same direction, in the last twenty years, 300,000 slaves. While not
4000 had gone to Africa. What it portended, he could not predict, but
he felt deeply, that _we must awake in these states and consider the
subject_."

Hon. PHILIP DODDRIDGE, of Virginia, in his speech in the Virginia
Convention, in 1829, [Debates p. 89.] said:--

"The acquisition of Texas will greatly _enhance th
