Several plausible reasons are assigned why the three slave States of Maryland, Virginia, and North Carolina voted for this prohibition. First, the West was competing with the Territory of Maine for settlers; second, the whole scheme was in the interest of the "Ohio Company," a newly formed Massachusetts emigrant aid society which immediately made a large purchase of lands; third, the unsettled regions south of the Ohio River had not yet been ceded to the general Government, and were therefore open to slavery from the contiguous Southern States; fourth, little was known of the extent or character of the great West; and, therefore, fifth, the Ohio River was doubtless thought to be a fair and equitable dividing line. The ordinance itself provided for the formation of not less than three nor more than five States, and under its shielding provisions Ohio, Indiana, Illinois, Michigan, and Wisconsin were added to the Union with free constitutions. [Sidenote: "Ellior's Debates," Vol. V., p. 395.] [Sidenote: Ibid., p. 392.] It does not appear that sectional motives operated for or against the foregoing enactment; they were probably held in abeyance by other considerations. But it must not be inferred therefrom that the slavery question was absent or dormant in the country. There was already a North and a South. At that very time the constitutional convention was in session in Philadelphia. George Washington and his fellow delegates were grappling with the novel problems of government which the happy issue of the Revolution and the lamentable failure of the Confederation forced upon the country. One of these problems was the presence of over half a million of slaves, nearly all in five Southern States. Should they be taxed? Should they be represented? Should the power to regulate commerce be allowed to control or terminate their importation? Vital questions these, which went not merely to the incidents but the fundamental powers of government. The slavery question seemed for months an element of irreconcilable discord in the convention. The slave-trade not only, but the domestic institution itself, was characterized in language which Southern politicians of later times would have denounced as "fanatical" and "incendiary." Pinckney wished the slaves to be represented equally with the whites, since they were the Southern peasantry. Gouverneur Morris declared that as they were only property they ought not to be represented at all. Both the present and the future balance of power in national legislation, as resulting from slaves already in, and hereafter to be imported into, old and new States, were debated under various possibilities and probabilities.
