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.

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 after it; but when I got to it it warn't nothing but a couple of sawlo
