Summer on the Lakes, in 1843
“With what gusto does Father Hennepin describe "this great downfall of water," "this vast and prodigious cadence of water, which falls down after a surprising and astonishing manner, insomuch that the universe does not afford its parallel.”
Fuller, Margaret. Summer on the Lakes, in 1843. Boston: Little, Brown & Co., 1844.
Inferred Fuller names Father Hennepin explicitly and quotes him at length. The passage matches the 1698 English-language edition of A New Discovery of a Vast Country in America, which reads (with early modern spelling): 'Betwixt the Lake Ontario and Erie, there is a vast and prodigious Cadence of Water which falls down after a surprizing and astonishing manner, insomuch that the Universe does not afford it's parallel.
