“This morning early, before our departure, we saw a large herd of the big-horned animals, which were bounding among the rocks on the opposite cliff with great agility. These inaccessible spots secure them from all their enemies, and their only danger is in wandering among these precipices, where we would suppose it scarcely possible for any animal to stand; a single false step would precipitate them at least five hundred feet into the water. “At one and one fourth miles we passed another single cliff on the left; at the same distance beyond which is the mouth of a large river emptying from the north. It is a handsome, bold, and clear stream, eighty yards wide--that is, nearly as broad as the Missouri--with a rapid current, over a bed of small smooth stones of various figures. The water is extremely transparent; the low grounds are narrow, but possess as much wood as those of the Missouri. The river has every appearance of being navigable, though to what distance we cannot ascertain, as the country which it waters is broken and mountainous. In honor of the Secretary of War we called it Dearborn’s River.” General Henry Dearborn, who was then Secretary of War, in Jefferson’s administration, gave his name, a few years later, to a collection of camps and log-cabins on Lake Michigan; and in due time Fort Dearborn became the great city of Chicago. Continuing, the journal says: “Being now very anxious to meet with the Shoshonees or Snake Indians, for the purpose of obtaining the necessary information of our route, as well as to procure horses, it was thought best for one of us to go forward with a small party and endeavor to discover them, before the daily discharge of our guns, which is necessary for our subsistence, should give them notice of our approach. If by an accident they hear us, they will most probably retreat to the mountains, mistaking us for their enemies, who usually attack them on this side.” . . . . . . . . . Captain Clark was now in the lead with a small party, and he came upon the remains of several Indian camps formed of willow-brush, Traces of Indians became more plentiful. The journal adds:--
