"You leave all that to me, Mr. Stoodles," said Bob. "I'll guarantee a perfect job."

"It's all for Dave's sake, lad, so I know you will," declared Stoodles.

The eccentric but loyal Irishman now went to the stateroom occupied by Doctor Barrell.

"Docther," he said, entering the presence of the old scientist, "I'd be telling you something."

Doctor Barrell was very busy examining some seaweed specimens he had fished up in the cove, but he graciously received the visitor, who was quite a favorite with him.

"Speak right out, Mr. Stoodles," he said.

Pat narrated his plans in behalf of Dave Fearless. Doctor Barrell was interested.

"And how can I help you?" he inquired, when Stoodles had finished talking.

"Docther dear, it's the loan of your phonnygraph I'd be wanting."

Doctor Barrell looked serious. He had a remarkably fine phonograph outfit, receiver and transmitter attachments, and all up to date.
