[Sidenote: Mr. McLane's argument against the amendment.]
Mr. McLane, of Delaware, a Commonwealth whose legislature had instructed the representatives from the Commonwealth in Congress to support all measures for preventing the spread of slavery in the Territories of the Union west of the Mississippi, presented the question with even greater clearness and conciseness. He simply analyzed the words of the Constitution which make up the clause conferring power on Congress "to admit new States into this Union." He said that the power to admit was not the power to create; that the very use of the word presupposed that the power to create the "State" resided elsewhere than in Congress; that Congress must admit a _"State,"_ not a Territory or a province or anything but a _"State;"_ that a "State," in the system of federal government of the United States, was an organization whose powers and duties had been determined by the Constitution of the United States itself, and could not be altered by Congressional definitions and limitations; that Congress must admit the "State" into _this Union_, not into some other union; and that _this Union_ was a system of federal government, in which the relations between the general Government { 82} and the "States" had been fixed by the Constitution of the United States, and could not be altered by a mere Congressional act. This was strong reasoning, and it had a powerful effect upon the minds of all who heard it and of all who read it.
[Sidenote: The independent Missouri bill of the Senate.]
Meanwhile events were occurring in the Senate which were to exercise a controlling influence over the fate of the bill in the House. On December 29th, 1819, a memorial from the Territorial legislature of Missouri, praying for the admission of that part of the Territory already described in the memorial to the House, had been presented in the Senate, and referred to the Judiciary committee. On January 3rd, 1820, the House bill admitting Maine was sent into the Senate. Mr. James Barbour, of Virginia, immediately gave notice of his intention to move the connection of the two subjects in the same bill, and on the same terms. As we have seen, Mr. Clay had already made this suggestion in the House, but had not formally proposed it.
