     Many of the stories written by Mark Twain take place in Hannibal, Missouri. The

small wooden house where he lived as a boy still stands there. Next to the house is a

wooden fence. It is the kind described in Twain's book, "The Adventures of Tom

Sawyer, "published in1876.

     In that story, Tom has been told to paint the fence. He does not want to do it. But

he acts as if the job is great fun. He tricks other boys into believing this. His trick is so

successful that they agree to pay him money to let them finish his work. "The Adventures

slavery. They travel together on a raft made of wood down the Mississippi River. Huck

describes the trip: "It was lovely to live on the raft. Other places seem so cramped up

and smothery, but a raft don't. You feel mighty free and easy and comfortable on a raft...

Sometimes we'd have that whole river to ourselves for the longest time...We had the

sky up there, all speckled with stars, and we used to lay on our backs and look up at

them …"
