These lines are the last in the novel. By the final chapter, most everything has been resolved: Jim is free, Tom is on his way to recovering from a bullet wound, and Aunt Sally has offered to adopt Huck. Although Huck has come to like Sally and Silas, he knows they are still a part of the society he has come to distrust and fear. Aunt Sally’s intentions for Huck center around the upbringing that society thinks every boy should have: religion, clean clothes, education, and an indoctrination in right and wrong. Huck, however, has come to realize that the first two are useless and that, in reference to the third, he can provide a much better version for himself than can society. The “territories,” the relatively unsettled western United States, will offer Huck an opportunity to be himself, in a world not yet “sivilized” and thus brimming with promise. Weary of his old life, Huck contemplates ways to continue living with the same freedom he felt on the raft. Huck’s break from society is complete, and before the dust from his adventures is fully settled, he is already scheming to detach himself again.
Twain mentions his childhood friend Tom Blankenship as the inspiration for creating Huckleberry Finn in his autobiography: "In Huckleberry Finn I have drawn Tom Blankenship exactly as he was. He was ignorant, unwashed, insufficiently fed; but he had as good a heart as ever any boy had. His liberties were totally unrestricted. He was the only really independent person—boy or man—in the community, and by consequence he was tranquilly and continuously happy and envied by the rest of us. And as his society was forbidden us by our parents the prohibition trebled and quadrupled its value, and therefore we sought and got more of his society than any other boy's." – Mark Twain's Autobiography .
