Many of the States, on the adoption of the Constitution, or shortly afterward, took measures to abolish slavery within their respective jurisdictions; and it is a well-known fact that a belief was cherished by the leading men, South as well as North, that the institution of slavery would gradually decline, until it would become extinct. The increased value of slave labor, in the culture of cotton and sugar, prevented the realization of this expectation. Like all other communities and States, the South were influenced by what they considered to be their own interests. But if we are to turn our attention to the dark ages of the world, why confine our view to colored slavery? On the same principles, white men were made slaves. All slavery has its origin in power, and is against right. The power of Congress to establish Territorial Governments, and to prohibit the introduction of slavery therein, is the next point to be considered. After the cession of western territory by Virginia and other States, to the United States, the public attention was directed to the best mode of disposing of it for the general benefit. While in attendance on the Federal Convention, Mr. Madison, in a letter to Edmund Randolph, dated the 22d April, 1787, says: "Congress are deliberating on the plan most eligible for disposing of the western territory not yet surveyed. Some alteration will probably be made in the ordinance on that subject." And in the same letter he says: "The inhabitants of the Illinois complain of the land jobbers, &c., who are purchasing titles among them. Those of St. Vincent's complain of the defective criminal and civil justice among them, as well as of military protection." And on the next day he writes to Mr. Jefferson: "The government of the settlements on the Illinois and Wabash is a subject very perplexing in itself, and rendered more so by our ignorance of the many circumstances on which a right judgment depends. The inhabitants at those places claim protection against the savages, and some provision for both civil and criminal justice." In May, 1787, Mr. Edmund Randolph submitted to the Federal Convention certain propositions, as the basis of a Federal Government, among which was the following: "_Resolved_, That provision ought to be made for the admission of States lawfully arising within the limits of the United States, whether from a voluntary junction of government and territory or otherwise, with the consent of a number of voices in the National Legislature less than the whole." Afterward, Mr. Madison submitted to the Convention, in order to be referred to the committee of detail, the following powers, as proper to be added to those of general legislation: "To dispose of the unappropriated lands of the United States. To institute temporary Governments for new States arising therein. To regulate affairs with the Indians, as well within as without the limits of the United States."
