Some of the boys laughed. One of them, however, murmured, in an undertone, “What a great shame!”

Reginald’s color rose. He walked straight up to Thompson:

“Will you please to give me my knife again?”

Thompson looked surprised:

“I lent it to you to cut the string.”

“You did not say so.”

“I do not think it just of you to take my knife in that way,” said Reginald, thoroughly aroused; “and if you do not return it at once, I shall speak to Dr. Field about it.”

“Oh!” said Thompson, coolly; “you’re a sneak, are you?”
