promising to be on hand at the time set to start for Phantom Mountain.
Tom was up waiting for Mr. Jenks at twelve o'clock that night. Shortly after the hour he saw a dark figure steal into the orchard. At first he feared lest it might be one of the spies who were, he was now convinced, on the trail of the man who was seeking to discover the secret of the diamond makers. But a whistle, which came to the lad's ear a moment later (that being a signal Mr. Jenks had agreed to sound), told Tom that it was none other than the visitor he expected.
"All right, Mr. Jenks, I'm here," called Tom, cautiously. "Come over this way," and he went out from the shadow of the house, where he had been waiting, and met the men. "We'll go into my private work-shop," the youth added, leading the way.
"Have you decided to go with me?" asked Mr. Jenks, in an anxious whisper. "Did you find the diamonds to be real ones?"
"I did; and I'm going," spoke Tom.
"Good! That relieves my mind. But we are still in danger. I was followed by my shadower to-day, and only succeeded in shaking him off just before coming here. I don't believe he knows what I am about to do."
