What does huck learn?

I'm not sure what in particular you mean Huck does find out more about Jim's predicament. Huck inquires about the area, and the woman talks for over an hour about her problems. She finally gets to the news about Jim and Huck and tells him that there is a three hundred dollar bounty for capturing Jim. Apparently some of the townspeople believe that Jim killed Huck and ran away, while other people believe that Pap killed Huck. She tells Huck that she personally believes Jim is hiding out on Jackson's Island.
