Everyone voted the show a great success, and the children planned to have another one before they left Meadow Brook farm. But the Bobbsey twins did not know all that was in store for them before they went back to the city.
One day, when they were all seated at dinner in the pleasant Bobbsey farmhouse, Uncle Daniel paused, with a piece of pie half raised on his fork, and said:
"Hark!"
"What's the matter?" asked Aunt Sarah. "Did you think you heard the old ram coming again?"
"No, but it sounded like thunder," replied her husband, "and if it's going to rain I must hurry, and get those tomatoes picked."
"I heard something, too," said Mr. Bobbsey.
"So did I," spoke up Freddie. "Maybe it's the old black bull down in the pasture."
"No. There it goes again!" said Uncle Daniel. "It must be thunder!"
There sounded a dull distant booming noise, that was repeated several times.
Uncle Daniel got up hastily from the table and went to the door.
