This agrees with Mr. MADISON. The idea he conveys could scarcely have been more identical with Mr. MADISON if he had used MADISON'S words. When the Southern members of Congress voted unanimously for the 6th Article, or anti-slavery clause in the ordinance, with the proviso in respect to slaves escaping into the Territory, it was with the understanding that the Convention would insert a similar provision in the Constitution respecting slaves escaping from one State to another; and this--its insertion in both--was the compromise upon which the prohibition was inserted in the ordinance. Such is the concurrent testimony of Mr. MADISON and Mr. CALHOUN. We will now turn to the ordinance of 1787, and see whether it applies, as the one proposed by Mr. JEFFERSON in 1784 did, to the new States as well as to the Territories, and is the basis of State as well as Territorial Governments, and was so intended. It declares as follows: "For extending the fundamental principles of civil and religions liberty, which form the basis whereon these republics, their laws and constitutions, are erected; to fix and establish these principles as the basis of all laws, constitutions, and governments, which forever hereafter shall be formed in the said Territory; to provide also for the establishment of States and permanent governments therein, and for their admission to a share in the Federal councils, on an equal footing with the original States, at as early periods as may be consistent with the general interest. "It is hereby ordained and declared by the authority aforesaid: That the following articles shall be considered as articles of compact between the original States and the people and States in the said Territory, and forever remain unalterable, unless by the common consent." Then follows six articles of compact. Part of the fifth and the sixth are in these words: "ART. 5.... Whenever any of the said States shall have sixty thousand free inhabitants therein, such State shall be admitted, by its delegates, into the Congress of the United States, on an equal footing with the original States, in all respects whatever; and shall be at liberty to form a permanent Constitution and State Government; _provided_ the Constitutional Government, so to be formed, shall be republican and in conformity to the principles contained in these articles." "ART. 6. There shall be neither slavery nor involuntary servitude in the said Territory, otherwise than in the punishment of crimes, whereof the party shall have been duly convicted; _Provided, always_, That any person escaping into the same from whom labor or service is lawfully claimed in any one of the original States, such fugitive may be lawfully reclaimed, and conveyed to the person claiming his or her labor or service as aforesaid."
