This notice at the beginning of the story gives you a warning to what you will, or will not, find in this book. After reading through the reader will find that there is indeed no central plot and no central theme or motive. It is just about Huckleberry Finn, his relationships, hardships, and quite literally his adventures. It is telling the reader to not get too invested in trying to find something that is basically open to interpretation. 

Page 3. " You don't know about me, without you have read a book by the name of "The Adventures of Tom Sawyer," but that ain't no matter. "

The Adventures of Tom Sawyer is a novel by Mark Twain. The book was written and published prior to Adventures of  Huckleberry Finn, and Huckleberry was one of the main characters in it. That story told a lot about not only Tom Sawyer, but his relationship and adventures with Huckleberry. This quote is the beginning of a paragraph that gives some information about the previous book. This is important to the plot of this novel because Huckleberry is talking about the six thousand dollars the two had found hidden in a cave. This is vital to the story because it effects his relationship with his father and how he acts towards him, which is the motivation for many later events.   

Page 4. " Her sister, Miss Watson, a tolerable slim old maid, with goggles on, had just come to live with her "

Miss Watson is not really a main character so to speak, but she is important to an important theme in the story. She is the woman who is teaching Huckleberry. He is learning how to read, write, and from her. She is the sister of "the widow" with whom he lives. Her lessons and the fact that Huckleberry is actually learning something upsets his father who more than once asks him to quit, and threatens him with beatings. 

Page 10. " Here's Huck Finn, he ain't got no family- what are you going to do about him? "

Tom Sawyer decided to start a gang that was going to go around and rob and murder people. Of course Huckleberry wanted to be a part of it and was at their meeting where they were talking about what the gang was and establishing their rules. The group wasn't going ot include Huck because he doesn't have any beside his father, and the rules were that if they did something to wrong the gang their family would be killed. This is important in establishing his father's character even before he is introduced in the story. The whole town knows that his dad is a mean drunk who is barely ever around.

Page 20. " Then I turned around, and there he was. I used to be scared of him all the time, he tanned me so much "

Even though at first it is not clearly stated, with the previous information given we know that this is about Huckleberry's father. He was Huck's only family and didn't ever act like it unless there was something in it for him. The father was known as the town drunk, and Huck knew him to always be that way. It is made clear to the reader that the father does not care about his son, and just wants the money he and Tom Sawyer had found. The realtionship the two have is one of control and fear, and an abuse of power and beatings. 

Page 22. " It's so. You can do it. I had my doubts when you told me. Now looky here; you stop that putting on frills. I won't have it. I'll lay for you, my smarty; and if I catch you about that school I'll tan you good. First you know you'll get religion, too. I never see such a son "

This is where we find out where Huckleberry got his religious views from. Clearly his father is, or tries to act, religious. He knows he can get Huck to do what he wants by threatening him with religion.

Page 25. " He kept me with him all the time, and I never got a chance to run off. We lived in that old cabin, and he always locked the door. "

The widow tried to adopt Huckleberry for a number of reasons, but the main was to get him away from his dangerous father. When she tried this, the new judge decided that it was a bad idea and they shouldn't knowingly seperate families so Huck should stay with his dad. When this happened his father "got really upset" and threw a fit about the woman trying to take his son from him, so he was trying to sue. Knowing his character though we know that this was a ploy for money. But during this uproar the father "kidnapped" Huck and took him to a cabin in the woods where no one would find them and where he couldn't find his way out. He would go out and get drunk and leave Huck in the cabin locked up, and then come back and beat him. This proved what the readers already knew about their relationship.
