Tom described the fellow, and Mr. Jenks stated that this tallied with the appearance of the person who had been shadowing him.

“But we'll fool them yet!” cried Tom, who had now fully entered into the spirit of the affair. “If they can follow us in the Red Cloud they're welcome to. I think we'll get ahead of them.”

He then told of Mr. Damon and Mr. Parker, and Mr. Jenks agreed that it would add to the strength of the party to take these two gentlemen along.

“Though I can't say I care so much for Mr. Parker,” he added. “But now as to ways and means. When can we start?”

Thereupon he and Tom talked over details in the seclusion of the little office, and arranged to leave Shopton in about a week. In the meanwhile the airship would be overhauled, stocked with supplies and provisions, and be made ready for a swift dash to the mountains.

“And now I must be going,” said Mr. Jenks. “I have a great deal to do before I can start on this trip, and I hope I am not prevented by any of those men who seem to be trailing me.”

“How could they prevent you?” Tom wanted to know.

“Oh, there are any number of ways,” was the answer. “But I'm glad you found that my diamonds were real. We'll soon have plenty, if all goes well.”

As Mr. Jenks left the shop, he started back, in some alarm.

“What's the matter?” asked Tom.
