Even as he asked himself this important question he heard a sudden sharp "click!" that could only be made by the trigger of his dead-fall trap; then came a heavy, sodden, crunching sound, that told better than words what had happened. Frank jumped to his feet, shouting:

"Wake up! wake up! we've caught something, fellows. Wake up everybody!"

"Another fake alarm, I bet!" grumbled Larry.

"It's that miserable Elephant again," said Andy in disgust. "He ought to be taken down to the lake and ducked, that's what!"

"Me ducked? I'd like to see you do it!" shrilled a voice close beside
Andy, and which he recognized as belonging to the runt.

"Hey! Frank, what is it?" demanded Larry.

"Light up! we want to see something!" called Andy, now beginning to experience a strange sensation in the region of his heart, as the possibility of its being the genuine article of alarm struck home.
