Pebbles in the Library Book Drop
Every morning for two weeks, Camille found something peculiar when she emptied the library's book drop. Mixed in with the returned novels were small gray pebbles, each one painted with a white number. The first pebble said 1, the second said 2, and by Friday she was holding number nine.
"Somebody is counting," she told the librarian, Mr. Ito. "But I cannot figure out what."
Camille arranged the pebbles in a row on the desk. She examined the date stamps in the returned books, hoping to find a connection, and she noticed that every book in that day's pile had been either a mystery or an adventure. That gave her an idea. If the numbers matched a series of books, then the person might be keeping a tally of everything he or she had finished reading.
On Monday she arrived early and waited behind the shelves. At seven forty, a boy of about eight crept up to the slot, dropped in a thick book, and then reached into his pocket for a stone marked 15.
"Hello," Camille said gently. He jumped, and then he stared down at his shoes. "I don't have a card yet," he admitted. "My mom says I might lose it, so I make my own."
Camille smiled and walked him to the front desk, where Mr. Ito stamped a library card with the boy's name, Wes. Wes held it in both hands as though it were made of glass. Then he added his pebble to the jar beside the window, which the library kept on display from that day forward.
