“Git up and hump yourself, Jim!  There ain't a minute to lose.  They're after us!” Jim never asked no questions, he never said a word; but the way he worked for the next half an hour showed about how he was scared.  By that time everything we had in the world was on our raft, and she was ready to be shoved out from the willow cove where she was hid.  We put out the camp fire at the cavern the first thing, and didn't show a candle outside after that. I took the canoe out from the shore a little piece, and took a look; but if there was a boat around I couldn't see it, for stars and shadows ain't good to see by.  Then we got out the raft and slipped along down in the shade, past the foot of the island dead still--never saying a word. CHAPTER XII. IT must a been close on to one o'clock when we got below the island at last, and the raft did seem to go mighty slow.  If a boat was to come along we was going to take to the canoe and break for the Illinois shore; and it was well a boat didn't come, for we hadn't ever thought to put the gun in the canoe, or a fishing-line, or anything to eat.  We was in ruther too much of a sweat to think of so many things.  It warn't good judgment to put _everything_ on the raft. If the men went to the island I just expect they found the camp fire I built, and watched it all night for Jim to come.  Anyways, they stayed away from us, and if my building the fire never fooled them it warn't no fault of mine.  I played it as low down on them as I could.

We had mountains on the Missouri shore and heavy timber on the Illinois side, and the channel was down the Missouri shore at that place, so we warn't afraid o
