Note I-45 — Chapter I · ITINERARY: ST. LOUIS TO ST. PAUL, AUGUST 9TH-SEPTEMBER 21ST, 1805.
Reading edition
Billon's Ann. St. Louis, 1804-21, pub. 1888, p. 382, is obviously in error in stating that Pierre Rousseau embarked with Pike at St. Louis; for here we have him first hired at P. du C. I know nothing further of the man; but he is doubtless the one from whom Rousseau channel of the Miss. r., which runs past P. du C. on the Wis. side, as distinguished from the main steamboat channel past McGregor on the Iowan side, derived its name.
