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.

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.

Out of these divergent views grew the compromises of the Constitution. 1. The slaves were to be included in the enumeration for representation, five blacks to be counted as three whites. 2. Congress should have the right to prohibit the slave-trade, but not till the lapse of twenty years. 3. Fugitive slaves should be delivered to their owners. Each State, large or small, was allowed two senators; and the apportionment of representatives gave to the North thirty-five members and fourteen senators, to the South thirty members and twelve senators. But since the North was not yet free from slavery, but only in process of becoming so, and as Virginia was the leading State of the Union, the real balance of power remained in the hands of the South.

The newly formed Constitution went into successful operation. Under legal provisions already made and the strong current of abolition sentiment then existing, all the Eastern and Middle States down to Delaware became free. This gain, however, was perhaps more than numerically counterbalanced by the active importation of captured Africans, especially into South Carolina and Georgia, up to the time the traffic ceased by law in 1808. Jefferson had meanwhile purchased of France the immense country west of the Mississippi known as the Louisiana Territory. The free navigation of that great river was assured, and the importance of the West immeasurably increased. The old French colonies at New Orleans and Kaskaskia were already strong outposts of civilization and the nuclei of spreading settlements. Attracted by the superior fertility of the soil, by the limitless opportunities for speculation, by the enticing spirit of adventure, and pushed by the restless energy inherent in the Anglo-Saxon character, the older States now began to pour a rising stream of emigration into the West and the South-west.

In this race the free States, by reason of their greater population, wealth, and commercial enterprise, would have outstripped the South but for the introduction of a new and powerful influence which operated exclusively in favor of the latter. This was the discovery of the peculiar adaptation of the soil and climate of portions of the Southern States, combined with cheap slave-labor, to the cultivation of cotton. Half a century of experiment and invention in England had brought about the concurrent improvement of machinery for spinning and weaving, and of the high-pressure engine to furnish motive power. The Revolutionary war was scarcely ended when there came from the mother- country a demand for the raw fiber, which promised to be almost without limit. A few trials sufficed to show Southern planters that with their soil and their slaves they could supply this demand with a quality of cotton which would defy competition, and at a profit to themselves far exceeding that of any other product of agriculture. But an insurmountable obstacle yet seemed to interpose itself between them and their golden harvest. The tedious work of cleaning the fiber from the seed apparently made impossible its cheap preparation for export in large quantities. A negro woman working the whole day could clean only a single pound.

It so happened that at this juncture, November, 1792, an ingenious Yankee student from Massachusetts was boarding in the house of friends in Savannah, Georgia, occupying his leisure in reading law. A party of Georgia gentlemen from the interior, making a visit to this family, fell into conversation on the prospects and difficulties of cotton- culture and the imperative need of a rapidly working cleaning-machine. Their hostess, an intelligent and quick-witted woman, at once suggested an expedient. "Gentlemen," said Mrs. Greene, "apply to my young friend, Mr. Eli Whitney; he can make anything." The Yankee student was sought, introduced, and had the mechanical problem laid before him. He modestly disclaimed his hostess's extravagant praises, and told his visitors that he had never seen either cotton or cotton- seed in his life. Nevertheless, he went to work with such earnestness and success, that in a few months Mrs. Greene had the satisfaction of being able to invite a gathering of gentlemen from different parts of the State to behold with their own eyes the working of the newly invented cotton-gin, with which a negro man turning a crank could clean fifty pounds of cotton per day.
