In chapters 15 to 18 Jim and Huck are floating downriver, Jim searches the riverbank for the town of Cairo. Each time Jim mentions how soon he will be free, Huck feels even more guilty. Huck knows that helping Jim escape is breaking the law, but Jim is also his friend. Huck is having trouble deciding whether or not to help him. After a great deal of thinking and compromising, Huck realizes he will feel possibly even more guilty if he turned Jim into the authorities, and decides it would be best to just allow him escape. They float past the town of Cairo and keep heading south on the river. Then, their raft is rammed by a steamboat and Jim and Huck are seperated.
