"So the Old Man hasn't chawed you up?" remarked Preston, with a broad grin. "He's not a bad old lad when you know him. What's your name?"

Peter enlightened him.

"Dash it all!" exclaimed the Acting Chief. "I've heard of you, young fellah-me-lad! Weren't you in that Donibristle stunt? We've shipped a pukka hero this trip."

"Don't know about that," protested Peter. "The Old Man has just told me I'm a Jonah."

The erection was of solid construction, lighted by six brass-rimmed scuttles.
