"Come here," said Roswell, in a tone of authority.

Mark walked up to the desk.

"So you are the new boy?" said Roswell, after a close scrutiny.

"Yes."

"It would be a little more polite to say 'Yes sir.'"

"Yes, sir."

"What is your age?"

"Ten years."

"Humph! You are rather young. If I had been consulted I should have said 'Get a boy of twelve years old.'"

"I hope I shall suit," said Mark.
