“Never. I don’t see how a bird could sound so like a human being.”

“That’s what it is just the same,” said Grant, and he was almost doubled up with laughter now. “I think I’d better wake up Pop and Fred and tell them about your friend that’s calling for help.”

“Are you positive it’s a loon?”

“Absolutely.”

“Then don’t ever tell a soul,” begged John eagerly. “I’d never hear the last of it as long as I lived. It would be awful if George ever knew.”

“You’re not the first one who’s ever been fooled,” laughed Grant. “You probably won’t be the last, either.”

“Please don’t tell on me, though, Grant. Promise me you won’t.”

“We’ll see,” said Grant evasively. “I can’t make any promises though.”

“How should I know that it was a loon?” demanded John. “I never heard one before and you yourself say that other people have been fooled the same way.”

“That’s true. Still it’s almost too good a joke on you to keep.”
