The Constitution of the United States supplies the defect that existed in the articles of confederation, and has vested Congress, as has been stated, with ample powers on this important subject.  Accordingly, the ordinance of 1787, passed by the old Congress, was ratified and confirmed by an act of the new Congress during their first session under the Constitution.

The State of Virginia, which ceded to the United States her claims to this territory, consented by her delegates in the old Congress to this ordinance—­not only Virginia, but North Carolina, South Carolina, and Georgia, by the unanimous votes of their delegates in the old Congress, approved of the ordinance of 1787, by which slavery is forever abolished in the territory northwest of the river Ohio.

Without the votes of these States, the ordinance could not have passed; and there is no recollection of an opposition from any of these States to the act of confirmation, passed under the actual Constitution.  Slavery had long been established in these States—­the evil was felt in their institutions, laws, and habits, and could not easily or at once be abolished.  But these votes so honorable to these States, satisfactorily demonstrate their unwillingness to permit the extension of slavery into the new States which might be admitted by Congress into the Union.

The States of Ohio, Indiana, and Illinois, on the northwest of the river Ohio, have been admitted by Congress into the Union, on the condition and conformably to the article of compact, contained in the ordinance of 1787, and by which it is declared that there shall be neither slavery nor involuntary servitude in any of the said States.

Although Congress possess the power of making the exclusion of slavery a part or condition of the act admitting a new State into the Union, they may, in special cases, and for sufficient reasons, forbear to exercise this power.  Thus Kentucky and Vermont were admitted as new States into the Union, without making the abolition of slavery the condition of their admission.  In Vermont, slavery never existed; her laws excluding the same.  Kentucky was formed out of, and settled by, Virginia, and the inhabitants of Kentucky, equally with those of Virginia, by fair interpretation of the Constitution, were exempt from all such interference of Congress, as might disturb or impair the security of their property in slaves.  The western territory of North Carolina and Georgia, having been partially granted and settled under the authority of these States, before the cession thereof to the United States, and these States being original parties to the Constitution which recognizes the existence of slavery, no measure restraining slavery could be applied by Congress to this territory.  But to remove all doubt on this head, it was made a condition of the cession of this territory to the United States, that the ordinance of 1787, except the sixth article thereof, respecting slavery, should be applied to the
