But it was in the provisions of the Ordinance relative to the admission into the Union of the new States to be formed upon this territory, that the relation between the existing government of the United States and its great dependency was afterwards found to involve serious difficulties. The Union was at that time a confederacy of thirteen States, originally formed mainly with reference to the exigencies of the war; and, although the Articles of Confederation had been ratified under circumstances which gave to the United States the authority to acquire this property, they had vested in Congress no power to enlarge the Confederacy by the admission of new States. Yet the Ordinance undertook to declare that new States should be admitted into the Congress of the United States on an equal footing with the existing States in all respects whatever, without proposing to submit that question to the original parties to the Confederacy. It does not appear from contemporary evidence that this difficulty attracted public attention, at the time of the passage of the Ordinance. In the year 1787, the Confederation was laboring under far more pressing and alarming defects than the want of strict constitutional power to create new States. Public attention was consequently more engaged with the consideration of evils which affected the prosperity of the original States themselves, than with the destiny of the new communities, or the method by which they were to be brought into the Union. It was not immediately perceived, also, that a property, capable at no distant day of becoming a vast mine of wealth to the United States, as a great and independent revenue, had come under the management of a single body of men, constituted originally without reference to such a trust, and with no declared constitutional provisions for its administration. When, however, the Constitution was in the process of formation, the necessity for provisions under which Congress could dispose of the public lands, and by which new States could be admitted into the Union, was at once felt and conceded on all sides.[322]
