But Frank’s word was law; the Dart was anchored.

“Barney,” he said, “you and the captain may go. Look out for the captain.”

“All right, sor.”

Captain Bell was elated.

He had a queer sort of mania for treasure hunting, and he forgot all about the perils lately threatening in this desire.

Barney was not loth to go.

The Celt was inordinately fond of adventure, and here was a chance to distinguish himself.

So he put on his diving suit, and with Captain Bell left the Dart.

They soon reached the wreck and clambered aboard.

She was evidently some sort of a trading vessel, and had not been many months under the water.
