derous designs. From the three forks we went easterly, crossing by an easy pass the mountain chain which separates the headwaters of the Missouri from the Yellowstone river,
a distance of about forty miles. We followed in the track of the Flathead camp for several days, when I sent Gabriel, my interpreter, with a Pend d'Oreille Indian in advance to discover what direction the camp had taken, and to bring back speedy news regarding their movements; and also to learn the dispositions of the Crows, whom I designed to
visit. Four days later I was met by a few Flatheads on their way to find me, when I was apprised of the treachery of the Crows, and the severe chastisement they had so deservedly received. I traveled the whole of that night, and arrived next day in the allied camp, as I have already in
formed you. Having failed to obtain the desired interview with the Crows, our attention will be now turned toward the Blackfeet, with whose favorable disposition to receive the
gospel you are already acquainted. The result of this determination will form the subject of my next letter.
