On Saturday morning, Aunt Polly sends Tom out to whitewash the fence. Jim passes by, and Tom tries to get him to do some of the whitewashing in return for a “white alley,” a kind of marble. Jim almost agrees, but Aunt Polly appears and chases him off, leaving Tom alone with his labor.
A little while later, Ben Rogers, another boy Tom’s age, walks by. Tom convinces Ben that whitewashing a fence is great pleasure, and after some bargaining, Ben agrees to give Tom his apple in exchange for the privilege of working on the fence. Over the course of the day, every boy who passes ends up staying to whitewash, and each one gives Tom something in exchange. By the time the fence has three coats, Tom has collected a hoard of miscellaneous treasures. Tom muses that all it takes to make someone want something is to make that thing hard to get.
