somethin' less than a foot to th' mile; but if it warn't for th' big bottoms, that let some of th' water wander around awhile instid of crowdin' along all at once, we'd have a current that'd surprise you. Jest now I figger she's steppin' along about seven miles an hour. Durin' low water it's some'rs around two; but I've seen it nearer ten on some rises. There are places where steamboats can't beat th' current an' have to kedge up or wait for lower water. About gittin' to Independ[Pg 29]ence Landin', or what's left of it, I'll tell you that when we pass Liberty Landin'. Miles through th' water ain't miles over th' bottom, an' it's th' last that counts. Besides, th' weather has got a lot to say about our business. I hope you ain't gittin' chilled, Miss Cooper, this spring air cuts in amazin' after sundown." [Pg 29] "I am beginning to feel it," she replied, arising, "I'll say good night, I believe, and 'turn in.'" Tom escorted her to the lower deck and watched her cross the cabin and enter her room, for he had no illusions about some of the men on board. As her door closed he wheeled and went to look at the engines, which were connected directly to the huge paddle wheel. The engineer was getting ready to climb into his bunk, but he smoked a pipe with his visitor and chatted for a few minutes. Tom knew what it meant to be an engineer on a Missouri river packet and he did not stay long. He knew that his host scarcely took his hand from the throttle for a moment while the boat was moving, for he had to be ready to check her instantly and send her full speed astern. The over-worked system of communication between the pilot house and the engine room had received its share of his attention during his runs on the river. He next went forward along the main deck and looked at the boilers, the heat from them distinctly pleasing. As he turned away he heard and felt the impact from another great, trimmed log slipping along the faint, gray highway. Some careless woodcutter upstream had worked in vain. He stopped against the rail and looked at the scurrying water only a few feet below him, listening to its swishing, burbling complaints as it eddied along the hull, seeming in the darkness to have a speed incredi[Pg 30]ble. A huge cottonwood with its upflung branches and sunken roots paused momentarily as it struck a shallow spot, shivered, lost a snapping dead limb, collected a surprising amount of débris as it swung slowly around and tore free from the clutching mud of the bottom and, once more acquiring momentum, shot out of sight into the night, its slowly rising branches
