“Who took it?” demanded Bob, clenching his fists, as if he wanted to attack some one.

“Don’t know!” gasped Andy. “But—it’s gone. First—I thought—you fellows—had it out, but when—I came up here—and saw you sitting down—I knew it—wasn’t you. But it’s gone!”

“Come on, fellows!” commanded Jerry quickly. “Let’s see what’s up.”

Followed by Andy they hurried off toward the shed where the Comet was kept. This structure was some distance away from Jerry’s house. It had been specially built to house the airship, and was located in the midst of a large field, owned by Mrs. Hopkins, which field gave ample room for manœuvring the craft. It was some distance from a road, and in an unfrequented locality.

It did not take long to arrive at the place. Before they reached the shed they could see that the big doors were opened. So far Andy’s tale had been confirmed. A few minutes later the motor boys were staring into the empty shed. The big air craft was gone!

“It’s been stolen, boys!” exclaimed Jerry, as he stepped into the shed. “Our airship has been stolen!”

“And I’ll wager Noddy Nixon had a hand in it!” added Bob. “Let’s get right after him!”
