Moustier and Madame de Bréhan originally planned to make a more extensive tour of Virginia including stops at Richmond, the Natural Bridge, and Monticello, home of their friend Thomas Jefferson. They cut short their visit to the state because, in their opinion, “the season was too far advanced” and they already “had so much suffer’d from the cold” on their travels. Nevertheless, they were greatly pleased with GW and Mount Vernon. “Every thing there,” they wrote Jefferson, “is enchanting” (29 Dec. 1788, JEFFERSON  description begins Julian P. Boyd et al., eds. The Papers of Thomas Jefferson. 40 vols. to date. Princeton, N.J., 1950—. description ends , 14:399–400).
