"Then," said the professor, "I will see if it is proof against fire."

He deliberately unfolded it, crushed it in his hand, and then held it in the flame of a candle.

Rose uttered a low ejaculation.

"That's the last of your handkerchief, Rose," said Ben.

"You made me give it to him. You must buy me another," said the young lady.

"So I will, if you don't get it back safe."

"How can I?"

"I don't know. Perhaps the professor does," answered Ben.

"Really," said the professor, contemplating the handkerchief regretfully. "I am afraid I have destroyed the handkerchief; I hope the young lady will pardon me."

He looked at Rose, but she made no sign. She felt a little disturbed, for it was a fine handkerchief, given her by her aunt.
