While parsing through the Day By Day pages I came across a note about
Clemens and Bixby on board the RUFUS J. LACKLAND from 11 July to 3
August 1857, going up the Missouri River. Fears notes mention of this
on twainquotes ( http://www.twainquotes.com/Steamboats/CubPilot.html) .
I'm curious about any confirmations about this and possible schedules.
