Tom wakes up to the beautiful sound and variety of nature.
He looks around and plays with a few bugs before rousing his fellow pirates, and soon enough they've stripped down and started to play.
Once they've had their fill of play, they return to camp and make breakfast; Joe cooks up some bacon and some fish that Tom and Huck catch and they have themselves a good meal.
They spend the day lying around, exploring the island, swimming, and eating, but eventually homesickness gets the best of them.
Soon they notice the steam ferry, packed with people, off in the distance.
The boys realize someone's drowned, and watch the search party for a while until he realizes: they're the ones who've drowned.
Tom, Huck, and Joe take great pleasure in being thought dead – a strange fantasy if there ever was one – and they realize then just how sweet being a pirate can be.
When dusk comes and the search party gives up, the boys return to camp, cook supper, and then start talking about what the townspeople must be thinking.
This gets Tom and Joe to thinking that, you know, maybe, certain people wouldn't be so thrilled to hear that they had died. They feel guilty again.
When Joe proposes they return to civilization, however, Tom makes fun of him, and Huck joins in. Joe is convinced to give up the idea.
Once Joe and Huck fall asleep, however, Tom gets up, picks out two pieces of bark, and writes a message on each. He puts one in Joe's hat, along with a bunch of his various curiosities (marbles, a rubber ball), puts the other in his pocket, and makes his way toward the beach.
