of their companion. But Tad did not mind it at all. Throwing them
off with a prodigious effort he scrambled to his feet, dust-covered,
hatless and with hair in a sad state of disorder.

Professor Zepplin had thrust the other boys aside and was gripping
Tad's hands.

"It's the last time you ever get me to consent to your taking such a
chance," he said. "How did you get out? You certainly did not climb
up the side of the mountain."

"Oh, no," laughed Tad. "I knew there must be some way out, for I
found a moccasin track down there in the sand before I turned in last
night."

"You must have pretty good eyes to find a moccasin track in the dark,"
laughed Ned.

"I did not say it was dark. I made the discovery before that."

"Tell us about it," urged Walter.

"You didn't find any of Eagle-eye's evil spirits down there, did you?"
asked Ned.

"No. I wish I had. I should have been glad of company of any kind."

"We want to hear how you got out," spoke up Chunky. "I--I came pretty
near falling in after you, too."
