(p. 328) If we are to credit Jefferson’s story, the dinner held at his lodgings on Maiden Lane on June 20, 1790, fixed the future site of the capital. It is perhaps the most celebrated meal in American history, the guests including Jefferson, Madison, Hamilton, and perhaps one or two others. For more than a month, Jefferson had been bedeviled by a migraine headache, yet he presided with commendable civility. Despite his dislike of assumption, he knew that the stalemate over the funding scheme could shatter the union, and, as secretary of state, he also feared the repercussions for American credit abroad.
Madison restated his familiar argument that assumption punished Virginia and other states that had duly settled their debts. But he agreed to support assumption–or at least not oppose it–if something was granted in exchange. Jefferson recalled, “It was observed… that as the pill would be a bitter one to the southern states, something should be done to soothe them.” The sedative measure was that Philadelphia would be the temporary capital for ten years, followed by a permanent move to a Potomac site. In a lucrative concession for his home state, Madison also seems to have extracted favorable treatment for Virginia in a final debt settlement with the central government. In return, Hamilton agreed to exert his utmost efforts (p. 329) to get the Pennsylvania congressional delegation to accept Philadelphia as the provisional capital and a Potomac site as its permanent successor.
The dinner consecrated a deal that was probably already close to achievement. The sad irony was that Hamilton, the quintessential New Yorker, bargained away the city’s chance to be another London or Paris, the political as well as financial and cultural capital of the country. His difficult compromise testified to the transcendent value he placed on assumption. The decision did not sit well with many New Yorkers. Senator Rufus King was enraged when Hamilton told him that he “had made up his mind” to jettison the capital to save his funding system. For King, Hamilton’s move had been high-handed and secretive, and he ranted privately that “great and good schemes ought to succeed not by intrigue or the establishment of bad measures.”
