laid down by Judge Porter, (late United States Senator
from La.,) in his decision at the March term of the La. Supreme Court,
1830, Merry vs. Chexnaider, 20 Martin's Reps. 699.

That the ordinance abolished the slavery then existing there is also
shown by the fact, that persons holding slaves in the territory
petitioned for the repeal of the article abolishing slavery, assigning
_that_ as a reason. "The petition of the citizens of Randolph and St.
Clair counties in the Illinois country, stating that they were in
possession of slaves, and praying the repeal of that act (the 6th
article of the ordinance of '87) and the passage of a law legalizing
slavery there." [Am. State papers, Public Lands, v. 1. p. 69.] Congress
passed this ordinance before the United States' Constitution was
adopted, when it derived all its authority from the articles of
Confederation, which conferred powers of legislation far more restricted
than those committed to Congress over the District and Territories by
the United States' Constitution. Now, we ask, how does the Constitution
_abridge_ the powers which Congress possessed under the articles of
confederation?

The abolition of the slave trade by Congress, in 1808, is another
illustration of the competency of legislative power to abolish slavery.
The African slave trade has become such a mere _technic_, in common
parlance, that the fact of its being _proper slavery_ is overlooked. The
buying and selling, the transportation, and the horrors of the middle
passage, were mere _incidents_ of the slavery in which the victims were
held. Let things be called by their own names. When Congress abolished
the African slave trade, it abolished SLAVERY--supreme slavery--power
frantic with license, trampling a whole hemisphere scathed with its
fires, and running down with blood. True, Congress did not, in the
abolition of the slave trade, abolish all the slavery within its
jurisdiction, but it did abolish _all_ the slavery _in one_ part of its
jurisdiction. What has rifled it of power to abolish slavery in
_another_ part of its jurisdiction, especially in that part where it has
"exclusive legislation in all cases whatsoever?"

8. THE CONSTITUTION OF THE UNITED STATES RECOGNIZES THIS POWER BY THE
MOST CONCLUSIVE IMPLICATION. In Art. 1, sec. 3, clause 1, it prohibits
the abolition of the slave trade previous to 1808: thus implying the
power of Congress to do it at once, but for the restriction; and its
power t
