But while this dangerous subject was pending, the affairs of the country had taken a new turn. The Convention at Annapolis had been held, in the autumn of 1786, and the Convention called to revise the system of the federal government was to meet in May, 1787. It had become sure and plain, that a large increase of the powers of the national government was absolutely essential to the continuance of the Union and the prosperity of the States. Every day the situation of the country was becoming more and more critical. No money came into the federal treasury; no respect was paid to the federal authority; and all men saw and admitted that the Confederation was tottering to its fall. Some prominent persons in the Eastern States were suspected of leaning towards monarchy; others openly predicted a partition of the States into two or more confederacies; and the distrust which had been created by the project for closing the Mississippi rendered it extremely probable, that the Western country at least would be severed from the Union.
The advocates of that project recoiled, therefore, from the dangers which they had unwittingly created. They saw, that the crisis required that harmony and confidence should be studiously cherished, now that the great enterprise of remodelling the government upon a firmer basis was to be attempted. They saw that no new powers could be obtained for the Federal Constitution, if the government then existing were to burden itself with an act so certain to be the source of dissension, and so likely to cause a dismemberment of the Confederacy, as the closing of the Mississippi. Like wise and prudent men, therefore, they availed themselves of the expected and probable formation of a new government, as a fit occasion for disposing of this question; and after an effort to quiet the apprehensions that had been aroused, the whole matter was postponed, by general consent, to await the action of the great Convention of May, 1787.[349] After the Constitution had been formed and adopted, the negotiation was formally referred to the new federal government which was about to be organized, in March, 1789, with a declaration of the opinion of Congress that the free navigation of the river Mississippi was a clear and essential right of the United States, and ought to be so considered and supported.[350]
