JOURNAL. CHAP. I. ON Monday the 14th of May 1804, we lett our establishment at the mouth of the river du Bois or Wood rivet·, a small river which falls into the Mississippi, on the east side, a mile below the Mis­souri, and having crossed the Mississippi proceeded up the Missouri on our intended voyage of discovery, under the command of Captain Clarke. Captain Lewis was to join us in two or three days on our passage.* • The confluence of the Missouri and Mississippi rivers is in latitude about 38 degrees and forty minutes north, and in longitnde 92 degrees and an half west of London, or 17 and a third west of Philadelphia. The town of St. Louis is ·14 miles below the mouth of the Missouri on the west side of the Mississippi; ancl Cahokia about 4 or 5 miles lower down on the east side. The longitude of these places is • nearly the same with that of the mouth of the river St. Louis at the west end of lake Superior in 46 degrees 45 minutes north latitude; about 2 degrees west of New Or .. leans itt latitude 30 degrees north, and the same number ?f def?rees east of the most western point of Hudson's Bay, m latttude about 59 degrees north : So that a line drawn ft·om New Orleans to Fol't Churchhill, at the mouth of Churchhi1l river on the west side of Hudson's Bay, would pass very near the m~J uth of the Missouri and the west end of lake Superior. ·
