well, Tom said; he said he never see a thing work more satisfactory. He said it showed it was done right. So he said, now for the grand bulge!  So the very next morning at the streak of dawn we got another letter ready, and was wondering what we better do with it, because we heard them say at supper they was going to have a nigger on watch at both doors all night.  Tom he went down the lightning-rod to spy around; and the nigger at the back door was asleep, and he stuck it in the back of his neck and come back.  This letter said: Don't betray me, I wish to be your friend.  There is a desprate gang of cutthroats from over in the Indian Territory going to steal your runaway nigger to-night, and they have been trying to scare you so as you will stay in the house and not bother them.  I am one of the gang, but have got religgion and wish to quit it and lead an honest life again, and will betray the helish design. They will sneak down from northards, along the fence, at midnight exact, with a false key, and go in the nigger's cabin to get him. I am to be off a piece and blow a tin horn if I see any danger; but stead of that I will _baa_ like a sheep soon as they get in and not blow at all; then whilst they are getting his chains loose, you slip there and lock them in, and can kill them at your leasure.  Don't do anything but just the way I am telling you, if you do they will suspicion something and raise whoop-jamboreehoo. I do not wish any reward but to know I have done the right thing. _Unknown Friend._ CHAPTER XL. WE was feeling pretty good after breakfast, and took my canoe and went over the river a-fishing, with a lunch, and had a good time, and took a look at the raft and found her all right, and got home late to supper, and found them in such a sweat and worry they didn't know which end they was standing on, and made us go right off to bed the minute we was done supper, and wouldn't tell us what the trouble was, and never let on a word about the new letter
