What do you bring, oh, mighty river--and what tidings do you carry from the great mountains yonder in the unknown lands? In what region grew this great pine which swims with you to the sea? What fat lands reared this heavy trunk, which sinks at last, to be buried in the sands?
What jewels lie under your flood? What rich minerals float impalpably in your tawny waters? Across what wide prairies did you come--among what hills--through what vast forests? How long, great river, was your journey, sufficient to afford so tremendous a gathering of the waters?
A hundred years ago the great Missouri made no answer to these questions. It was open highway only for those who dared. The man who asked its secrets must read them for himself. What a time and place for adventure! What a time and place for men!
From sea to sea, across an unknown, fabled mountain range, lay our wilderness, now swiftly trebled by a miracle in statecraft. The flag which floated over the last stockade of Spain, the furthest outpost of France, now was advancing step by step, inch by inch, up the giant flood of the Missouri, borne on the flagship of a flotilla consisting of one flatboat and two skiffs, carrying an army whose guns were one swivel piece and thirty rifles.
Not without toil and danger was this enterprise to advance. When at length the last smoke of a settler's cabin had died away over the lowland forest, the great river began in earnest to exact its toll.
