The convention had been slow in assembling. Ample notice had been given that it would convene on May 13, 1787, but when that day arrived a mere handful of the delegates, less than a quorum, had assembled. The Virginia delegation, six in number, and forming probably the ablest delegation from any State, arriving in time, and failing to find a quorum then assembled, employed the period of waiting in submitting to the Pennsylvania delegation the outlines of a plan for the new Constitution. The plan was largely the work of James Madison, and how long it had been in preparation cannot be definitely stated. It is clear that four years before a Philadelphia merchant, one Peletiah Webster, had published a brochure proposing a scheme of dual sovereignty, under which the citizens would owe a double allegiance--one to the constituent States within the sphere of their reserved powers, and one to a federated government within the sphere of its delegated powers. Leagues of States had often existed, but a league which, within a prescribed sphere, would have direct authority over the citizens of the constituent States, without, however, abolishing the authority of such States as to their reserved sphere of power, was a novel theory. How far the Virginia project had been influenced by Webster's suggestion is not clear, but it is certain that before the convention met Pennsylvania and Virginia, two of the most powerful States, were committed to it. The suggestion was a radical one, for the States, with few exceptions, were chiefly insistent upon the preservation of their sovereignty, and while they were willing to amend the Articles of Confederation by giving fuller authority to the central government, such as it was, the suggestion of subordinating the States to a new sovereign power, whose authority within circumscribed limits was to be supreme, was opposed to all their conventions and traditions. Washington, however, had warmly welcomed the creation of a strong central government, and his correspondence with the leading men of the colonies for some years previously had been burdened with arguments to convince them that a mere league of States would not suffice to create a stable nation. To George Washington, soldier and statesman, is due above all men the ideal of a federated union, for without his influence--that of a noble and unselfish leader--the great result would probably never have been secured. While still waiting for the convention, to meet, and while discussing what was expedient and practicable when they did meet, Washington one day said to a group of delegates, who were considering the acute nature of the crisis:
