With anxious eyes the bully watched the first assistant disappear into the office with the compositions. Then, looking to make sure that he was not observed, he stole up to the door and applied his ear to the keyhole. What he heard filled him with increased alarm.

"It is Sobber's handwriting beyond a doubt," said Captain Putnam, after comparing the compositions with the address on the box cover. "I wonder if he knew that the snake was a poisonous one?"

"Perhaps Nick Pell can tell that—after he gets over his trouble," returned Dick.

"Provided he does get over it, Richard."

"Don't you think he'll recover?" cried Dick, in consternation.

"He may not. It is a very serious case, so Doctor Fremley informs me."

"What does Mr. Pell say about it?"

"He wants me to investigate. He says he may have somebody arrested for this—and I can hardly blame him. It was a vile thing to do—bring a poisonous snake into the school."

At the mention of arrest Tad Sobber shut his teeth hard.

"I guess it's about time I made myself scarce," he muttered. "Perhaps I had better leave and join Uncle Sid." And he walked away silently and up to his room. He remained there about ten minutes, then stole forth and down a back way, a fair-sized bundle under his arm.
