"So far as I can learn, that Indian girl is the only human being here who has ever seen the Stony Mountains. The girl says that she was taken captive years ago somewhere near the summit of the Stony Mountains. Above here a great river comes in, which they call the Yellow Rock River--the 'Ro'jaune,' Jussaume calls it. Very well. Many days' or weeks' journey toward the west, this river comes again within a half-day's march of the Missouri. That is near the summit of the mountains; and this girl's people live there."
"By the Lord, Merne, you're a genius for getting over new country!"
"Wait. I find the child very bright--very clear of mind. And listen, Will--the mind of a woman is better for small things than that of a man. They pick up trifles and hang on to them. I'd as soon trust that girl for a guide out yonder as any horse-stealing warrior in a hurry to get into a country and in a hurry to get out of it again. Raiding parties cling to the river-courses, which they know; but she and her people must have been far to the west of any place these adventurers of the Minnetarees ever saw. Sacajawea she calls herself--the 'Bird Woman.' I swear I look upon that name itself as a good omen! She has come back like a dove to the ark, this Bird Woman. William Clark, we shall reach the sea--or, at least, you will do so, Will," he concluded.
