“Was I—did I dream it?” he asked, passing his hand over his head. “Is the airship all right? Was Noddy Nixon here? Did he hit me?” and he felt of the back of his head.

“The airship is gone,” replied Jerry. “What happened, Sud? Were you attacked? Was Noddy Nixon here in the night?”

“He was, or else I dreamed it,” declared the watchman. “He struck me, too, and then I don’t remember what happened, except I smelled something funny. Then it got dark, and I heard noises—but you say the airship’s gone?”

“Completely,” broke in Bob.

“Then we must get right after Noddy Nixon, and the old man, and Jack Pender, who were with him!” declared Sud excitedly, trying to rise, but falling weakly back.

“Easy now, take it easy,” advised Jerry soothingly. “We’ll get after him, all right. But you must first tell us what happened. Do you feel strong enough?”

“Oh, yes, I’m all right now,” replied the watchman. “I’m getting better every minute. I’ll tell you as much as I know.”

“Take a little of this medicine and you’ll feel stronger,” advised Jerry, holding a glass to the man’s lips. When Sud had partaken of it, he resumed:

“It must have been about eleven o’clock last night, when I was just getting ready to turn in, that I heard some persons coming to the shed. By the way they walked I knew there was more than one, and I was wondering if you boys had decided to make a night trip, without speaking to me about it. Well, I went to the door, when there came a knock on it—the small back door, you know,” he said, and the boys nodded comprehendingly. “You can imagine my surprise when I saw Noddy Nixon, and two persons with him. Noddy walked right in, as if he owned the place, and told the others to come in, too.”
