The puppy, meanwhile, sat down and industriously scratched his neck.

But after that a spirit of adventure seized him, and he cast an inquiring glance over the breathless assembly. Then he moved forward and sniffed tentatively at the damp boots of Todd, who stood in the middle of the front line. Todd held his breath and turned pale. But Muggins evidently didn’t fancy wet leather, for he moved off down the line, sniffing here and there, but without enthusiasm. Once he paused and cocked an interrogatory brown eye up at Williams. And it was Williams’s turn to wish himself away. He frowned darkly, threateningly, and Muggins, scenting animosity, turned tail. Williams heaved a sigh of relief.

Muggins now crawled laboriously between the feet of the next youth, and found himself confronted by a second rank of motionless, silent, and unsympathetic persons. He began to feel nervous. He stopped and, pointing his blunt nose toward heaven, howled long and dismally. Some one laughed, and the spell of terror was broken. Even Professor Wheeler smiled, while Muggins, delighted at the evidence of companionship, wagged his tail and began his search anew. Dick and Trevor stood, backs to the wall, in the last of the three lines. Trevor watched the puppy, scowling ferociously. The suspense was awful. He never for an instant doubted that sooner or later Nemesis in the shape of Muggins would find him out. Meanwhile he frowned, clenched his fists, and waited for his doom. His doom when it came came speedily.

Muggins had apparently lost interest in the proceedings, and had begun to whine softly, when suddenly he stopped dead short, and putting his head aloft, twitched the wrinkled end of his pink nose and sniffed suspiciously. One ear went up at an animated angle, and he put his little bullet-shaped head on one side. Professor Wheeler moved softly forward to a point where he could better watch events, and Trevor, after one annihilating glance at the puppy, stared straight before him. Muggins squirmed through the second rank, showing signs of strong excitement. And then—

Then there was a yelp of triumph, of delight, and Muggins was leaping deliriously at Trevor, giving vent to his joy in short explosive barks and gurgling yelps.

“I won’t keep you any longer,” said the principal. “If any of you are late at recitations, you may explain that it was my fault. I will ask Nesbitt to remain for a few minutes.”

And with grins of relief and amusement the forty-one boys crowded forth, leaving Trevor standing there alone, very red in the face, and with the puppy clasped close in his arms. Then the principal and Trevor and Muggins adjourned to the inner room. And there, while Muggins lay curled contentedly against the boy’s breast—simply because he couldn’t be induced to stay anywhere else—Trevor, rather haltingly, explained.

“And you had the dog in your study ever since Saturday?”

“Yes, sir.”

“But how—I can’t understand why no one discovered it. Didn’t the ‘goody’ see it there?”
