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.
