"Yes, sir. I never saw that picture before."

"But I have the proof against you!" fairly shouted Abner Sharp. "It is
useless for you to deny your guilt."

"I say I am not guilty."

"Isn't this your box, Rover?"

As Professor Sharp uttered these words he brought to light a German
silver case which Tom had picked up in a curiosity shop in New York.
The case had his name engraved on it, and contained pencils, crayons,
and other things for drawing.

"Where did you get that?" demanded the youth.

"Never mind where I got it. Isn't it yours?"

"Yes."

"Ha! Do you hear that, Doctor Wallington?" cried Abner Sharp in
triumph. "He admits the outfit is his!"

"So I see," said the president of Brill, and if anything his face
grew a trifle more stern. "Then you admit your guilt, Rover?" he
questioned.

"What! That I defaced the photograph?"

"Yes."
