over boundless territories, the use of which cannot fail to react upon the political system of the States, to its subversion, was ever within the contemplation of the statesmen who conducted the counsels of the people in the formation of this Constitution? When the questions that came to the surface upon the acquisition of Louisiana were presented to the mind of Jefferson, he wrote: "I had rather ask an enlargement of power from the nation, where it is found necessary, than to assume it by a construction which would make our powers boundless. Our peculiar security is in the possession of a written Constitution. Let us not make it blank paper by construction. I say the same as to the opinion of those who consider the grant of the treaty-making power as boundless. If it is, then we have no Constitution. If it has bounds, they can be no others than the definitions of the powers which that instrument gives. It specifies and delineates the operations permitted to the Federal Government, and gives the powers necessary to carry them into execution." The publication of the journals of the Federal Convention in 1819, of the debates reported by Mr. Madison in 1840, and the mass of private correspondence of the early statesmen before and since, enable us to approach the discussion of the aims of those who made the Constitution, with some insight and confidence. I have endeavored, with the assistance of these, to find a solution for the grave and difficult question involved in this inquiry. My opinion is, that the claim for Congress of supreme power in the Territories, under the grant to "dispose of and make all needful rules and regulations respecting _territory_," is not supported by the historical evidence drawn from the Revolution, the Confederation, or the deliberations which preceded the ratification of the Federal Constitution. The ordinance of 1787 depended upon the action of the Congress of the Confederation, the assent of the State of Virginia, and the acquiescence of the people who recognised the validity of that plea of necessity which supported so many of the acts of the Governments of that time; and the Federal Government accepted the ordinance as a recognised and valid engagement of the Confederation. In referring to the precedents of 1798 and 1800, I find the Constitution was plainly violated by the invasion of the rights of a sovereign State, both of soil and jurisdiction; and in reference to that of 1804, the wisest statesmen protested against it, and the President more than doubted its policy and the power of the Government.
