“We’d go with you anyway,” Bob told him, “only Karl says there isn’t another landing place near.”
Without loss of time the three continued toward the level spot on which the aviator had landed, at length coming in sight of the monoplane.
Karl rushed out to meet them, his face bright at finding that all were alive and well.
“You old rascal!” cried Joe, shaking the young man’s hand warmly.
“How’d you know we were here?” asked Bob, who was also very glad to see the aviator.
“I saw you,” Karl Sutman explained. “I thought I’d take a short flight over this section to see if I could locate you.”
“You did, all right.” Joe was delighted. “Found us away out here in the wilds.” He hesitated a moment and glanced at Dr. Rander. But the latter had already been introduced to Karl Sutman, and needed no introduction by the youths.
There was one question in the aviator’s mind that he could wait no longer to ask.
“The treasure you were searching for—did you find any?” he inquired. “And the Inca secrets, too. How about them?”
Bob smiled happily.
