I think that now, Mark Twain is building the plot up. Two key characters have been introduced: Huckleberry Finn and Becky Thatcher. I think that Tom Sawyer and his mischievous attitude, Huckleberry Finn with his lack of rules and restrictions, and Becky Thatcher, Tom's new love interest, will make up the main characters for the rest of the story.
Tom Sawyer has shown to be a static character so far. He continues to show the same reckless attitude throughout the story. His actions are humorous, but not surprising. Tom's character is revealed through his actions and his words. He tends to be lippy when it comes to what he says and does.
One artistic device I've noticed a lot in this novel, is diction. Diction is the style of writing according to the choice of words. Mark Twain has excellent diction in my opinion. The way he words things is impeccable. It makes the chapters easy and entertaining to read. It forces me to learn new words and expand my vocabulary.
In this chapter it mentions that Tom Sawyer uses a slate to write on in school. One website I found shows various 'Victorian writing tools'. One of these is a slate. http://www.ehow.com/list_6778502_victorian-writing-tools.html

ets, they receive a Bible. Tom always was neglecting to memorize his verses and had no chance of getting that Bible. But Tom, being the mischievous boy he was, traded different trinkets and tools with other boys and girls for their tickets. By the end of the Sunday School class, Tom had been presented with a Bible. He was soaking in pride as everyone watched in jealousy. But when he was asked a question about the verses he supposedly memorized, he completely embarrassed himself.
