Meriwether Lewis: September 18, 1803

18th September The morning was clear and having had every thing in readiness the over night we set out before sunrise and at nine in the morning passed Letart’s falls; being nine miles distant from our encampment of the last evening — this rappid is the most considerable in the whole course of the Ohio, except the rappids as they ar called opposite to Louisville in Kentuckey — the descent at Letart’s falls is a litte more than 4 four feet in two hundred fifty yards.
