North Western territory, abolished the
slavery then existing there. The Supreme Court of Mississippi, in its
decision in the case of Harvey vs. Decker, Walker's Mi. Reps. 36,
declared that the ordinance emancipated the slaves then held there. In
this decision the question is argued ably and at great length. The
Supreme Court of La. made the same decision in the case of Forsyth vs.
Nash, 4 Martin's La. Reps. 395. The same doctrine was laid down by Judge
Porter, (late United States Senator from La.,) in his decision at the
March term of the La. Supreme Court, 1830, in the case of 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
conferred on 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 r
