So, in two seconds, away we went, a sliding down the river, and it did seem so good to be free again and all by ourselves on the big river and nobody to bother us. I had to skip around a bit, and jump and crack my heels a few times, I couldn’t help it; but about the third crack, I noticed a sound that I knowed mighty well – and held my breath and listened and waited – and sure enough, when the next flash busted out over the water, here they come! – and just a laying to their oars and making their skiff hum! It was the king and the duke.

– Mark Twain

The Adventures of Huckleberry Finn, Chapter 29. Huck after helping expose the swindlers the Duke and King and escaping from them on the raft with Jim. But this time the Mississippi no longer symbolizes freedom for Huck and Jim, as the con duo catch up with them in a small boat.
