All hearts beat loudly.

"There is a boat!" whispered Carl. "Come on."

He dropped into the sea, and the others did the same.

Not far away floated a log, and to this they clung.

They paddled with their hands, and were soon some distance away from the submarine monster.

Then they cried for help.

The boat they had seen came in their direction.

They were seen, and the natives from the island let out a shout.

Then suddenly Captain Vindex appeared on the deck of the Searcher.

He shook his fist at the party.
