footholds with their knives in the sides of the banks. In this way they travelled through the rain, mud, and water, and having made only eighteen miles during the whole day, camped in an old Indian lodge of sticks, which afforded them a dry shelter. Here they cooked part of six deer they had killed in the course of their walk, and having eaten the only morsel they had tasted during the whole day, slept comfortably on some willow-boughs.” Chapter X -- To the Great Falls of the Missouri Next day, June 8, the Lewis party returned to the main body of the expedition.

After pondering all the evidence that could be collected to bear on the important question, the two captains agreed that the southern stream was the true Missouri, and the northern stream was an important branch.
