When we returned ... a Province man was betraying his greenness to the Yankees by his questions. Why Province money won't pass here at par, when States' money is good at Fredericton,—though this, perhaps, was sensible enough. From what I saw then, it appears that the Province man was now the only real Jonathan, or raw country bumpkin, left so far behind by his enterprising neighbors that he didn't know enough to put a question to them. No people can long continue provincial in character who have the propensity for politics and whittling, and rapid traveling, which the Yankees have, and who are leaving the mother country behind in the variety of their notions and inventions. The possession and exercise of practical talent merely are a sure and rapid means of intellectual culture and independence.
Henry David Thoreau (1817–1862), U.S. philosopher, author, naturalist. "Ktaadn" (1848) in The Maine Woods (1864), in The Writings of Henry David Thoreau, vol. 3, p. 16, Houghton Mifflin (1906).
Thoreau's use of "Jonathan" is double edged here, as it was under this name, meaning "son of John" (i.e., "John Bull"MEngland), that the United States was then personified.
