"Why, Dave, when I was shut in with the machine in that basin, I took it apart. You know it was made to do that, so it could be shipped readily. Well, I'll bet you I hid those parts in places in that basin where nobody can locate them but myself."

"Good for you!" commended Dave heartily.

"I think the Interstate people will have something pleasant to say to you when they know all the wonders you've done in chasing their stolen airship."

It was the brightest day in the year, it seemed to the two young aviators, as they reached Columbus by train, and started at once for Mr. King's hangar.

Old Grimshaw had met them at the depot. He was full of friendly chatter, seemed to be chuckling over some secret surprise he had in store for them, and rushed them towards the headquarters of the Aegis.

"Yes, Mr. King is back," he advised the boys.

"Did he find Mr. Dale?" inquired Dave anxiously.

"He'll tell you."

Dave and Hiram had much to relate. Two boys probably never received a more pleasant welcome than they, when with the Drifter they reported to the manager of the Interstate Aeroplane Company.

Mr. Randolph had the president and two directors of the concern on hand to meet them. Their stirring story was taken in by the august business men with an attention and appreciation that of itself paid the lads well for all the duty done.
