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.
