Tommy looked at what Bobsey called the "badge," and saw that several buttons were missing.

"They'll have to buy you a new one," said Bobsey, consolingly. "Vell, vot did the old duffer want?"

"His chimney smokes, and they want me to stop it."

Bobsey's eyes twinkled with a delight he could not conceal.
