"Too late! Bless my soul, too late for what?" gasped Mr. Damon, somewhat alarmed by Tom's manner.

"Father has just sent me a message," he said. "It's a warning flashed through space! He's been trying to get it to me since yesterday!"
"What is it?" asked Mr. Jenks, rising from his seat.
"The mysterious man is aboard the airship—hidden away!" cried Tom. "That's what Eradicate was trying to call to our attention as we started off. Eradicate saw his face at a rear window, and tried to warn us! The mysterious man is a stowaway on board!"
