In the book Huckleberry Fin, Mark Twain, tries to show the intolerance and injustice of the society of the South in the times of civil war through the eyes of a child. Among with other stereotypical southern behaviors, Huck is intolerant towards slaves. He sees black people as property belonging to the person who buys him or her without any feelings characteristic to humans. He constantly uses the term "nigger", and enjoys a laugh at a slave's expense. Huck spends most of his adventures down the rivers with a runaway salve Jim. Huck new Jim since he was a child in his old town. In fact, Huckleberry and his best friend Tom, play a rather crude joke on Jim. They tie Jim to a tree while he is sleeping, and allow him to believe that it was all witches. .
When Huck pretends to be dead to get away from his father, he encounters Jim, who has also renounced his master, at an abandoned island. Despite his prejudice towards Jim, Huck is very happy to see him. He decides to work together with Jim. Huck grows attached to his only companion, although he still shows signs of bigotry. He doesn't let Jim go out at daytime because he believes that "People will see [Jim] as a nigger from miles off." One day, when Huck went into the cave where he and Jim slept, Huck saw a snake lying in the corner. He killed it and left its skin inside Jim's bed as a joke. Unfortunately, Huck forgot that the snakes mate would sleep next to his dead wife. Jim got bit by the snake and developed a rather sever immune reaction. Huck nurses Jims wound, and feels responsible; however, he doesn't apologize to Jim.
When Huck and Jim have to flee, they grow closer and closer together. Jim sees Huck as the best friend he ever had; nonetheless, Huck only perceives Jim as runaway black man. Shortly before their arrival into the Free states, Huck and Jim are separated due to a very thick fog. They drift in two different vessels on the opposite sides of an island.
