The Sundial That Ran an Hour Slow
In Fenwick Park stood a stone sundial with a brass pointer, and a sign beside it said that it had kept good time for a hundred years. So when Odette's watch said ten o'clock and the sundial said nine, she was sure that something had broken.
Her brother Cal checked his own watch, and it agreed with hers. "Maybe the pointer is bent," he said, but when they looked closely, it was perfectly straight. "Maybe the stone has sunk," said Odette. A pencil laid across the top showed that the stone was level.
They came back at noon and again at three, and each time the sundial was behind by about the same amount.
"If something were bent or tilted, the mistake would change during the day," Odette said. "This one stays the same, because it is always an hour behind."
Cal frowned, and then his face lit up. "Last spring, the whole town moved its clocks ahead one hour so that we would get more light in the evening. Our watches changed, but the sun did not."
Mr. Ames, the gardener, had been listening while he raked. "That is the answer," he said. "A sundial follows the sun and not the clock, so in the autumn, when the clocks go back, the two will agree again."
Odette wrote the answer on a card and tucked it under the sign.
