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 budge 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 untied her. I got up and tried to untie 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 mighty fidgety business to have to hold your hands still at such a time. I whooped and listened. Away down there somewheres I hears a small whoop, 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.

I did wish the fool would think to beat a tin pan, and beat it all the time, but he never did, and it was the still places between the whoops that was making the trouble for me. Well, I fought along, and directly I hears the whoop BEHIND me. I was tangled good now. That was somebody else's whoop, or else I was turned around.

I throwed the paddle down. I heard the whoop again; it was behind me yet, but in a different place; it kept coming, and kept changing its place, and I kept answering, till by and by it was in front of me again, and I knowed the current had swung the canoe's head down-stream, and I was all right if that was Jim and not some other raftsman hollering. I couldn't tell nothing about voices in a fog, for nothing don't look natural nor sound natural in a fog.

The whooping went on, and in about a minute I come a-booming down on a cut bank with smoky ghosts of big trees on it, and the current throwed me off to the left and shot by, amongst a lot of snags that fairly roared, the currrent was tearing by them so swift.

In another second or two it was solid white and still again. I set perfectly still then, listening to my heart thump, and I reckon I didn't draw a breath while it thumped a hundred.

I just give up then. I knowed what the matter was. That cut bank was an island, and Jim had gone down t'other side of it. It warn't no towhead that you could float by in ten minutes. It had the big timber of a regular island; it might be five or six miles long and more than half a mile wide.

I kept quiet, with my ears cocked, about fifteen minutes, I reckon. I was floating along, of course, four or five miles an hour; but you don't ever think of that. No, you FEEL like you are laying dead still on the water; and if a little glimpse of a snag slips by you don't think to yourself how fast YOU'RE going, but you catch your breath and think, my! how that snag's tearing along. If you think it ain't dismal and lonesome out in a fog that way by yourself in the night, you try it once -- you'll see.

Next, for about a half an hour, I whoops now and then; at last I hears the answer a long ways off, and tries to follow it, but I couldn't do it, and directly I judged I'd got into a nest of towheads, for I had little dim glimpses of them on both sides of me -- sometimes just a narrow channel between, and some that I couldn't see I knowed was there because I'd hear the wash of the current against the old dead brush and trash that hung over the banks. Well, I warn't long loosing the whoops down amongst the towheads; and I only tried to chase them a little while, anyway, because it was worse than chasing a Jack-o'-lantern. You never knowed a sound dodge around so, and swap places so quick and so much.

I had to claw away from the bank pretty lively four or five times, to keep from knocking the islands out of the river; and so I judged the raft must be butting into the bank every now and then, or else it would get further ahead and clear out of hearing -- it was floating a little faster than what I was.

Well, I seemed to be in the open river again by and by, but I couldn't hear no sign of a whoop nowheres. I reckoned Jim had fetched up on a snag, maybe, and it was all up with him. I was good and tired, so I laid down in the canoe and said I wouldn't bother no more. I didn't want to go to sleep, of course; but I was so sleepy I couldn't help it; so I thought I would take jest one little cat-nap.

But I reckon it was more than a cat-nap, for when I waked up the stars was shining bright, the fog was all gone, and I was spinning down a big bend stern first. First I didn't know where I was; I thought I was dreaming; and when things began to come back to me they seemed to come up dim out of last week.

It was a monstrous big river here, with the tallest and the thickest kind of timber on both banks; just a solid wall, as well as I could see by the stars. I looked away down-stream, and seen a black speck on the water. I took............
