"That settles it!" exclaimed the young inventor.

"Settles what?" asked Ned.

"The manner of Mr. Damon's disappearance. He was taken away—or went away—in my airship—the airship that was stolen from my shed last night!"

Mrs. Damon stared at Tom in amazement.

"Why—why—how could that be?" she asked.
