This illustration is from Mark Twain's The Adventures of Tom Sawyer. It's from the part of the story where Tom and Joe Harper skip school and, with Huckleberry Finn, sneak away to Jackson's Island to spend a few days swimming, fishing, and generally goofing off. While on the island they see a bunch of boats take to the river, firing shots into the water and circling around. They know that this is how searchers attempt to get bodies to resurface and wonder with interest who has drowned. It gradually dawns on the boys that it is the three of them who are presumed dead. Further shenanigans ensue, including showing up at their own funeral.
