The next day was Sunday, but the flat kept on her way. I cooked my meals upon the rusty stove, and we floated side by side, conversing hour after hour. The low banks of the river showed the presence of levees, or artificial dikes, built to keep out the freshets. Upon these dikes the grass was putting forth its tender blades, and the willows were bursting into leaf. We passed White River and the Arkansas, both of which pour their waters out of the great wilderness of the state of Arkansas. Below the mouth of the last-named river was the town of Napoleon, with its deserted houses, the most forlorn aspect that had yet met my eye. The banks were caving into the river day by day. Houses had fallen into the current, which was undermining the town. Here and there chimneys were standing in solitude, the buildings having been torn down and removed to other localities to save them from the insatiable maw of the river. These pointed upward like so many warning cenotaphs of the river's treachery, and contrasted strongly in the mind's eye with the many happy family circles which had once gathered at their bases around the cheerful hearths. About ten o'clock in the forenoon the proprietor of the flatboat decided, as it was Sunday, to run into a bend of the river and tie up for the day. That night the banks caved in so frequently that I was in danger of being entombed in my sneak-box; and I rejoiced when morning came and the dangerous quarters were left behind. My flatboat companions made known to me a curious feature of river physics well known to the great floating population of the western streams. If you start with a flat-boat or raft of timber from any point on the Ohio or Mississippi rivers at the moment a rise in the water takes place, and continue floating night and day without interruption, you will in a few days overrun the effects of the rise, or freshet, and get below it. A little later you will discover, at some point a few hundred miles down-stream, that the river is just commencing to swell, as the result of the freshet upon which you originally started. During Tuesday and Wednesday of January 11 and 12, I was at times with the flat, and at times miles away from it. Near Skipwith Landing, Mississippi, we passed large and well-cultivated cotton-plantations, but the river country in its vicinity was almost a wilderness.
