It is true that by subsequent explorations it was ascertained that the source of the Tugaloo river, upon which the title of South Carolina depended, was so far to the northward, that the transfer conveyed only a narrow slip of land, about twelve miles wide, lying on the top of the ridge of mountains, and extending from the northern boundary of Georgia to the southern boundary of North Carolina. But this was a discovery made long after the cession, and there can be no doubt that the State of South Carolina, in making the cession, and the Congress in accepting it, viewed it as a transfer to the United States of the soil and jurisdiction of an extensive and important part of the unsettled territory ceded by the Crown of Great Britain by the treaty of peace, though its quantity or extent then remained to be ascertained.[5] [Footnote 5: _Note by Mr. Justice Curtis._ This statement that _some_ territory did actually pass by this cession, is taken from the opinion of the court, delivered by Mr. Justice Wayne, in the case of Howard _v._ Ingersoll, reported in 13 How., 405. It is an obscure matter, and, on some examination of it, I have been led to doubt whether any territory actually passed by this cession. But as the fact is not important to the argument, I have not thought it necessary further to investigate it.] It must be remembered also, as has been already stated, that not only was there a confident expectation entertained by the other States, that North Carolina and Georgia would complete the plan already so far executed by New York, Virginia, Massachusetts, Connecticut, and South Carolina, but that the opinion was in no small degree prevalent, that the just title to this "back country," as it was termed, had vested in the United States by the treaty of peace, and could not rightfully be claimed by any individual State. There is another consideration applicable to this part of the subject, and entitled, in my judgment, to great weight. The Congress of the Confederation had assumed the power not only to dispose of the lands ceded, but to institute Governments and make laws for their inhabitants. In other words, they had proceeded to act under the cession, which, as we have seen, was as well of the jurisdiction as of the soil. This ordinance was passed on the 13th of July, 1787. The Convention for framing the Constitution was then in session at Philadelphia. The proof is direct and decisive, that it was known to the Convention.[6] It is equally clear that it was admitted and understood not to be within the legitimate powers of the Confederation to pass this ordinance.
