Territorial disputes have at all times been found one of the most fertile sources of hostility among nations. Perhaps the greatest proportion of wars that have desolated the earth have sprung from this origin. This cause would exist among us in full force. We have a vast tract of unsettled territory within the boundaries of the United States. There still are discordant and undecided claims between several of them, and the dissolution of the Union would lay a foundation for similar claims between them all. It is well known that they have heretofore had serious and animated discussion concerning the rights to the lands which were ungranted at the time of the Revolution, and which usually went under the name of crown lands. The States within the limits of whose colonial governments they were comprised have claimed them as their property, the others have contended that the rights of the crown in this article devolved upon the Union; especially as to all that part of the Western territory which, either by actual possession, or through the submission of the Indian proprietors, was subjected to the jurisdiction of the king of Great Britain, till it was relinquished in the treaty of peace. This, it has been said, was at all events an acquisition to the Confederacy by compact with a foreign power. It has been the prudent policy of Congress to appease this controversy, by prevailing upon the States to make cessions to the United States for the benefit of the whole. This has been so far accomplished as, under a continuation of the Union, to afford a decided prospect of an amicable termination of the dispute. A dismemberment of the Confederacy, however, would revive this dispute, and would create others on the same subject. At present, a large part of the vacant Western territory is, by cession at least, if not by any anterior right, the common property of the Union. If that were at an end, the States which made the cession, on a principle of federal compromise, would be apt when the motive of the grant had ceased, to reclaim the lands as a reversion. The other States would no doubt insist on a proportion, by right of representation. Their argument would be, that a grant, once made, could not be revoked; and that the justice of participating in territory acquired or secured by the joint efforts of the Confederacy, remained undiminished. If, contrary to probability, it should be admitted by all the States, that each had a right to a share of this common stock, there would still be a difficulty to be surmounted, as to a proper rule of apportionment. Different principles would be set up by different States for this purpose; and as they would affect the opposite interests of the parties, they might not easily be susceptible of a pacific adjustment.
