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
