It appears that during the preparation of the Articles of Confederation an effort was made to include in them a grant of express power to the United States in Congress to ascertain and fix the western boundaries of the existing States, and to lay out the territory beyond the boundaries that were to be thus ascertained into new States. This effort totally failed. It was founded upon the idea that the land beyond the rightful boundaries of the old States was already, or would by the proposed grant of power to ascertain those boundaries become, the common property of the Union. But the States, which then claimed an uncertain extension westward from their actual settlements, were not prepared for such an admission, or such a grant; and accordingly the Articles of Confederation, which were issued in 1777 and took effect in 1781, contained no express power to deal with landed property of the United States, and no provision which could safely be construed into a power to form and admit new States out of then unoccupied lands anywhere upon the continent. Still, the Articles were successively ratified by some of the States, and finally became established, in the express contemplation that the United States should be made the proprietor of such lands, by the cession of the States which claimed to hold them. In order to procure such cessions, as the means of inducing a unanimous accession to the confederacy, the Congress in 1780 passed a resolve, in which they promised to dispose of the lands for the common benefit of the United States, to settle and form them into distinct republican States, and to admit such States into the Union on an equal footing with its present members.[272] The great cession by Virginia, made in 1784, was immediately followed by another resolve, for the regulation of the territory thus acquired.[273]
