"Well, at any rate remember that you are living in the United States. Shake hands and go back to your work, and I hope you will have no further trouble."

Frank somewhat reluctantly shook hands with Bob and they walked out of the principal's office together. At the door of the study room Frank turned to Bob. "I shook hands with you then because I had to," he snapped. "I warn you though, I'll never do it again, and you'll be sorry for what you did to me this morning. Yes, you and your whole family!"

Bob was completely taken aback by this sudden outburst but before he could make any reply Frank was gone. Bob walked slowly to his desk, carefully avoiding the glances of the many boys in the room who looked curiously at him and his black, swollen eye.

When school closed that afternoon he hurried away as quickly as he could, for he had no desire to discuss the matter with his schoolmates. Around the corner he waited for Hugh and together the two boys started homeward.

"What did Mr. Hewitt say?" asked Hugh.

Bob told him.

"Good for him," exclaimed Hugh. "What did Frank think of that?"

"He was mad," said Bob, and he told his friend of the threat Frank had made. Hugh was silent for some time.

"We must watch him pretty closely," he said at length.

"Yes," Bob agreed, "and his father too."
