The Constitution permits Congress to dispose of and to make all needful rules and regulations respecting the territory or other property belonging to the United States. This power applies as well to territory belonging to the United States within the States, as beyond them. It comprehends all the public domain, wherever it may be. The argument is, that the power to make "ALL needful rules and regulations" "is a power of legislation," "a full legislative power;" "that it includes all subjects of legislation in the territory," and is without any limitations, except the positive prohibitions which affect all the powers of Congress. Congress may then regulate or prohibit slavery upon the public domain within the new States, and such a prohibition would permanently affect the capacity of a slave, whose master might carry him to it. And why not? Because no power has been conferred on Congress. This is a conclusion universally admitted. But the power to "make rules and regulations respecting the territory" is not restrained by State lines, nor are there any constitutional prohibitions upon its exercise in the domain of the United States within the States; and whatever rules and regulations respecting territory Congress may constitutionally make are supreme, and are not dependent on the _situs_ of "the territory." The author of the Farmer's Letters, so famous in the ante-revolutionary history, thus states the argument made by the American loyalists in favor of the claim of the British Parliament to legislate in all cases whatever over the colonies: "It has been urged with great vehemence against us," he says, "and it seems to be thought their FORT by our adversaries, that a power of regulation is a power of legislation; and a power of legislation, if constitutional, must be universal and supreme, in the utmost sense of the word. It is therefore concluded that the colonies, by acknowledging the power of regulation, acknowledged every other power." This sophism imposed upon a portion of the patriots of that day. Chief Justice Marshall, in his life of Washington, says "that many of the best-informed men in Massachusetts had perhaps adopted the opinion of the parliamentary right of internal government over the colonies;" "that the English statute book furnishes many instances of its exercise;" "that in no case recollected, was their authority openly controverted;" and "that the General Court of Massachusetts, on a late occasion, openly recognised the principle." (Marsh. Wash., v. 2, p. 75, 76.)
