Any one who has seen an outward-bound clipper ship getting under way and heard the "shanty-songs" sung by the sailors as they toiled at capstan and halliards, will probably remember that rhymeless but melodious refrain-- "I'm bound to see its muddy waters Yeo ho! that rolling river; Bound to see its muddy waters Yeo ho! the wild Missouri." Only a happy inspiration could have impelled Jack to apply the adjective "wild" to that ill-behaved and disreputable river, which, tipsily bearing its enormous burden of mud from the far North-west, totters, reels, runs its tortuous course for hundreds on hundreds of miles; and which, encountering the lordly and thus far well-behaved Mississippi at Alton, and forcing its company upon this splendid river (as if some drunken fellow should lock arms with a dignified pedestrian), contaminates it all the way to the Gulf of Mexico. At a certain point on the banks of this river, or rather--as it has the habit of abandoning and destroying said banks--at a safe distance therefrom, there is a town from which a railroad takes its departure for its long climb up the natural incline of the Great Plains, to the base of the mountains; hence the importance to this town of the large but somewhat shabby building serving as terminal station. In its smoky interior, late in the evening and not very long ago, a train was nearly ready to start. It was a train possessing a certain consideration. For the benefit of a public easily gulled and enamored of grandiloquent terms, it was advertised as the "Denver Fast Express;" sometimes, with strange unfitness, as the "Lightning Express"; "elegant" and "palatial" cars were declared to be included therein; and its departure was one of the great events of the twenty-four hours, in the country round about. A local poet described it in the "live" paper of the town, cribbing from an old Eastern magazine and passing off as original, the lines-- "Again we stepped into the street, A train came thundering by, Drawn by the snorting iron steed Swifter than eagles fly. Rumbled the wheels, the whistle shrieked, Far rolled the smoky cloud, Echoed the hills, the valleys shook, The flying forests bowed." The trainmen, on the other hand, used no fine phrases. They called it simply "Number Seventeen"; and, when it started, said it had "pulled out."
