What do Tom and huck do to confuse her completely?

As Tom, Huck and Jim start to move away from the hut, Tom gets caught on the fence and his britches rip quite loudly. All three start to run, and the farmers shoot after them. When they get to a dark area, Huck, Jim, and Tom hide behind a bush and let the whole pack of farmers and dogs run past them.Once safe, they proceed to where the raft is hidden and Tom tells Jim he is a free man again, and that he will always be a free man from now on. Jim thanks him and tells him it was a great escape plan. Tom then shows them where he got a bullet in the leg, but Jim is worried for Tom's health.
