There was some little time to wait after all their preparations were made, for the Express was late, as usual, and in the interim the boys and the professor struck up quite an acquaintance with Mr. Harrison and his daughter. Bob even insisted on buying a lot of sandwiches to take along on the train, for he said he might get hungry in the night journey to Denver.

“Well, it’s better than staying in town all night,” remarked Jerry, when the agent informed him that their train would soon pull in. “But I wish we had caught the Limited.”

“Well, maybe we’ll get ahead of Noddy yet,” suggested Ned.

The Express pulled in, and a score of hungry passengers besieged pretty Miss Harrison. She waved good-bye to the boys and the professor, and then began handing out food. Our friends got aboard, and settled themselves comfortably for the trip to Denver. At last they were underway again.

Through the night rushed the Express. Jerry and his friends had taken sleeping berths, and they stretched out for a long rest, as they were tired. There was some regret that Noddy was ahead of them, but this could not be helped.

“What do you think Noddy will do when he gets to Denver; if he arrives ahead of us?” asked Ned of Jerry, who had the berth below him.

“I don’t know. I hope he doesn’t find out where our airship is, and try to damage that.”

“He wouldn’t dare!”

“Oh, Noddy would do anything. Still, there’s no use in worrying until we have to.”
