A moment the girl looked at him: “I’m not in the least tired, Mr. Watson!” she exclaimed; “and I don’t mind what those two boys are saying, if you don’t.”

“But I do,” returned Harry, “on your account. For that reason I think it’s best that you join your friends.”

“But you’re my friend, aren’t you?”

“I hope so, that is, I should like to be.”

“Well, I certainly consider you so,” returned the girl, and again taking hold of hands, they skated away, laughing and chatting merrily; and continued to skate together till it was time for them to go to their homes to supper.

Light of heart to think he had been cleared of the charges of depredations in the physical laboratory, and successful in defeating the skaters from Springtown, Harry was in a happy frame of mind as he mounted the steps of his aunt’s house, and went in to supper. But one sight of his aunt’s face drove all his joy away.

“What is it, Aunt Mary? Have you heard about the trouble at the school? Don’t worry, because there’s nothing in it.”

The thought that her nephew had been concerned in some difficulty of which she was ignorant struck still further grievance to the woman.

“No, I haven’t heard about it. What is it, tell me?”

“Oh, it doesn’t amount to much. Merely that some apparatus was broken in the physical laboratory and they thought that I did it.”
