Slowly, Jack pulled himself to an upright position, discovering that he could stand without stooping. It was then that he made an exciting discovery.

The ceiling overhead had a distinct curve!

“This looks like part of an old tunnel!” he thought in elation.

Before Jack could investigate further, he heard a shout from above.

Mr. Livingston peered down through the narrow opening, calling anxiously:

“Jack, are you hurt?”

“Hardly a scratch,” the Scout replied with a chuckle. “This is a deep hole though, and I can’t get out by myself.”

“Stay where you are,” Mr. Livingston directed. “We’ll get a rope and haul you up.”

“Don’t be in too big a hurry, Hap. I want to look around a bit while I’m here. It appears to me that I’ve fallen into a tunnel.”

“A tunnel, Jack? What makes you think so?” The tone of Mr. Livingston’s voice plainly disclosed that the information had startled him.
