“I’m going to call her,” she said, and gave the familiar yodel on which Cora herself had relied in vain.
But no answer came back, and the girls looked at each other with unrest in their eyes.
“Do you think she’s teasing us by pretending not to hear?” asked Belle.
“No,” replied her sister, “that wouldn’t be like Cora. She knows how that would worry us.”
“Let’s try both together,” suggested Belle, and they gave out a call in unison.
Again there was no response, and thoroughly frightened now, the girls ran back to their companions.
“Oh, Jack,” exclaimed Belle, “we can’t find Cora!”
“What!” cried the boys, leaping to their feet.
“It’s true,” confirmed Bess. “We’ve called her again and again, and we can’t get any answer.”
Jack grew pale beneath his coat of tan.
