It is clear that the origin of the provision in that form was s. 8(17) of Art. 1 of the Constitution of the United States which provides:
The Congress shall have Power To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States, and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings.
The first part of cl. 17, relating to the seat of government, is said to have been prompted by occurrences which took place near the close of the Revolutionary War when Congress in session in Philadelphia was surrounded and insulted by a body of mutineers of the Continental Army and the State did little to assist [6] . The second part, dealing with places purchased with the consent of the State, was thought necessary so that the consent of the State would carry with it political dominion and legislative authority. This was before the right of eminent domain was recognized [7] , and the view was that, in the case of land acquired without consent, the possession of the United States would be simply that of an ordinary proprietor subject to the legislative authority and control of the State [8] .
