This brings us to examine by what provision of the Constitution the present Federal Government, under its delegated and restricted powers, is authorized to acquire territory outside of the original limits of the United States, and what powers it may exercise therein over the person or property of a citizen of the United States, while it remains a Territory, and until it shall be admitted as one of the States of the Union. There is certainly no power given by the Constitution to the Federal Government to establish or maintain colonies bordering on the United States or at a distance, to be ruled and governed at its own pleasure; nor to enlarge its territorial limits in any way, except by the admission of new States. That power is plainly given; and if a new State is admitted, it needs no further legislation by Congress, because the Constitution itself defines the relative rights and powers, and duties of the State, and the citizens of the State, and the Federal Government. But no power is given to acquire a Territory to be held and governed permanently in that character. And indeed the power exercised by Congress to acquire territory and establish a Government there, according to its own unlimited discretion, was viewed with great jealousy by the leading statesmen of the day. And in the Federalist, (No. 38,) written by Mr. Madison, he speaks of the acquisition of the Northwestern Territory by the confederated States, by the cession from Virginia, and the establishment of a Government there, as an exercise of power not warranted by the Articles of Confederation, and dangerous to the liberties of the people. And he urges the adoption of the Constitution as a security and safeguard against such an exercise of power.
