Huck outsmarts Pap when he saws a hole in the wall and when he uses pig’s blood to fake his death.
Huck started planning his escape when he got tired of his father beating him. He developed an elaborate plan because they were alone in a cabin and there wasn’t even a window large enough for him to get out.
I got under the table and raised the blanket, and went to work to saw a section of the big bottom log out—big enough to let me through. … I got rid of the signs of my work, and dropped the blanket and hid my saw, and pretty soon pap come in. (Ch. 6)
When Pap returns, he is drunk and gets drunker. He wakes up with nightmares that there are snakes crawling over him and the chases Huck around with a knife calling him the Angel of Death. After he falls asleep, Huck takes the shotgun and sits up all night watching him.
Huck finds a drift-canoe in the river and hides it so that his father won’t find it. Huck then uses a pig to fake his death.
I took the axe and smashed in the door. I beat it and hacked it considerable a-doing it. I fetched the pig in, and took him back nearly to the table and hacked into his throat with the axe, and laid him down on the ground to bleed… (Ch. 7)
The trick works. Huck is able to get away, and heads down the river. He meets up with Jim, the escaped slave. Both Huck and Jim are running away from terrible situations. Huck is not sure at first whether he wants to be friendly with Jim, because it is against the law to assist a fugitive slave. However, after a while he comes to the conclusion that if helping Jim is wrong, then he doesn’t want to be right.
