"I don't think so," replied Tom. "The store-room is far enough off so that he couldn't hear us. Besides, the motor makes such a racket that he couldn't distinguish what we were talking about, even if he heard our voices. So, unless he heard the wireless working, and suspects something from that, he probably doesn't know that we are aware of his presence aboard."
"But why do you think he has remained quiet all this while, Tom?" asked Mr. Damon.
"Probably he wants to wait until the ship is farther out west," suggested Mr. Jenks. "Then he will be nearer his friends, and can get help, if he needs it."
"And do you really believe he would destroy the Red Cloud?" asked Mr. Parker.
"I think that all he is waiting for is a favorable chance," declared the diamond seeker. "He would destroy the craft, and us too, if he could prevent us from discovering the secret of Phantom Mountain, I believe."
"Then we must get ahead of him," decided Tom, quietly. "I have just flashed to dad a message, telling him that we will heed his warning. Now to capture the stowaway!"
"And while we're about it, give him a good scare when we do get him," suggested Mr. Jenks.
