The ordinance for the government of the territory northwest of the river Ohio had contained a provision which prohibited the use of servile labor therein, subject to the condition of the extraditions of fugitives from service due in any other part of the United States. Subsequently to the adoption of the Constitution this provision ceased to remain as a law, for its operation as such was absolutely superseded by the Constitution. But the recollection of the fact excited the zeal of social propagandism in some sections of the Confederation, and when a second State, that of Missouri, came to be formed in the territory of Louisiana proposition was made to extend to the latter territory the restriction originally applied to the country situated between the rivers Ohio and Mississippi. Most questionable as was this proposition in all its constitutional relations, nevertheless it received the sanction of Congress, with some slight modifications of line, to save the existing rights of the intended new State. It was reluctantly acquiesced in by Southern States as a sacrifice to the cause of peace and of the Union, not only of the rights stipulated by the treaty of Louisiana, but of the principle of equality among the States guaranteed by the Constitution. It was received by the Northern States with angry and resentful condemnation and complaint, because it did not concede all which they had exactingly demanded. Having passed through the forms of legislation, it took its place in the statute book, standing open to repeal, like any other act of doubtful constitutionality, subject to be pronounced null and void by the courts of law, and possessing no possible efficacy to control the rights of the States which might thereafter be organized out of any part of the original territory of Louisiana. In all this, if any aggression there were, any innovation upon preexisting rights, to which portion of the Union are they justly chargeable? This controversy passed away with the occasion, nothing surviving it save the dormant letter of the statute. But long afterwards, when by the proposed accession of the Republic of Texas the United States were to take their next step in territorial greatness, a similar contingency occurred and became the occasion for systematized attempts to intervene in the domestic affairs of one section of the Union, in defiance of their rights as States and of the stipulations of the Constitution. These attempts assumed a practical direction in the shape of persevering endeavors by some of the Representatives in both Houses of Congress to deprive the Southern States of the supposed benefit of the provisions of the act authorizing the organization of the State of Missouri.
