"What for?" Blake wanted to know.

"It might be loaded—go off, you know!"

"Nonsense!" exclaimed Blake. "It's probably only some sort of foreign alarm clock, and he stuffed it in there so the ticking wouldn't keep him awake. I've done the same thing when I didn't want to get up. I used to chuck mine under the bed, or stuff it in an old shoe. What's the matter with you, anyhow?

"But we heard a curious ticking noise when we came down here, and we traced it to your bunk. We didn't know what it might be, and thought perhaps you had put your watch in the bed, and might have forgotten to take it out. We looked, and found this—"

"Ah, my new alarm clock!" exclaimed Mr. Alcando, and what seemed to be a look of relief passed over his face. He reached in among the bed clothes and picked up the curious brass-bound ticking box, with its many little metallic projections.
