in the elk. About 10 o’clock Captain Lewis and Captain
Clarke with the party accompanying them came to camp; but
had not been able to discover any of those small people. The

some timber land on the south side: and black and white
bluffs on the same side, we encamped on the north side oppo-
site a creek called Pettit-Ark, or Little-bow.
