“Oh, dear me!” cried Tess suddenly, “I hear it, too. I guess it’s no game. It’s somebody calling.”

“Calling the cows, maybe,” said Agnes carelessly.

“Calling the sheep,” joined in Neale O’Neil.

“No,” said Dot soberly, “It’s calling humans. It said ‘Help!’ and they don’t call cows or sheep that way.”

“Right for you, Dotums!” agreed Agnes.

“Wait,” advised Neale. “All keep still and listen. Of course it isn’t Ruth and Luke? They wouldn’t get so far away——”

“Listen!” broke in Agnes warningly.

They all heard it that time—a cry of faint voices, and certainly the only word distinguishable was “help.”

“What can it be?” demanded Agnes.

“Like to know what they want us to help ’em about,” said Sammy. “Maybe it’s some fun.”
