CHAPTER XVI. WE slept most all day, and started out at night, a little ways behind a monstrous long raft that was as long going by as a procession.  She had four long sweeps at each end, so we judged she carried as many as thirty men, likely.  She had five big wigwams aboard, wide apart, and an open camp fire in the middle, and a tall flag-pole at each end.  There was a power of style about her.  It _amounted_ to something being a raftsman on such a craft as that. We went drifting down into a big bend, and the night clouded up and got hot.  The river was very wide, and was walled with solid timber on both sides; you couldn't see a break in it hardly ever, or a light.  We talked about Cairo, and wondered whether we would know it when we got to it.  I said likely we wouldn't, because I had heard say there warn't but about a dozen houses there, and if they didn't happen to have them lit up, how was we going to know we was passing a town?  Jim said if the two big rivers joined together there, that would show.  But I said maybe we might think we was passing the foot of an island and coming into the same old river again.
