WE judged that three nights more would fetch us to Cairo, at the bottom of Illinois, where the Ohio River comes in, and that was what we was after. We would sell the raft and get on a steamboat and go way up the Ohio amongst the free States, and then be out of trouble.

Well, the second night a fog begun to come on, and we made for a towhead to tie to, for it wouldn't do to try to run in a fog; but when I paddled ahead in the canoe, with the line to make fast, there warn't anything but little saplings to tie to. I passed the line around one of them right on the edge of the cut bank, but there was a stiff current, and the raft come booming down so lively she tore it out by the roots and away she went. I see the fog closing down, and it made me so sick and scared I couldn't budge¹ for most a half a minute it seemed to me -- and then there warn't no raft in sight; you couldn't see twenty yards. I jumped into the canoe and run back to the stern, and grabbed the paddle and set her back a stroke. But she didn't come. I was in such a hurry I hadn't untied² her. I got up and tried to untie³ her, but I was so excited my hands shook so I couldn't hardly do anything with them.

As soon as I got started I took out after the raft, hot and heavy, right down the towhead. That was all right as far as it went, but the towhead warn't sixty yards long, and the minute I flew by the foot of it I shot out into the solid white fog, and hadn't no more idea which way I was going than a dead man.

Thinks I, it won't do to paddle; first I know I'll run into the bank or a towhead or something; I got to set still and float, and yet it's mighty⁴ fidgety business to have to hold your hands still at such a time. I whooped⁵ and listened. Away down there somewheres I hears a small whoop⁶, and up comes my spirits. I went tearing after it, listening sharp to hear it again. The next time it come I see I warn't heading for it, but heading away to the right of it. And the next time I was heading away to the left of it -- and not gaining on it much either, for I was flying around, this way and that and t'other, but it was going straight ahead all the time.
