The instant that he saw Dan scrambling up he brought the oar down. Dan dodged the blow cleverly, the blade of the oar landing on the side of Black's head, thus finishing the work that the Battleship Boy had begun.

The two men sprang at each other at the same instant. This time the boy found that in White he had a far different antagonist. White met him with a swift blow which barely grazed Dan's head. Dan countered as best he could, planting a blow on the Hawaiian's chest, staggering the fellow and at the same time well-nigh upsetting the boat.

Blow after blow was struck in the rocking boat, now and then each of the contestants landing a staggering punch on his adversary's head. All at once Dan lost his footing and fell. As he did so, he stretched forth a hand, and by desperate effort succeeded in fastening his hold upon the Hawaiian's arm.

White lost his balance and pitched forward.

Both men fell half over the side of the dinghy with heads and shoulders in the sea. For the next few seconds a desperate struggle followed. Dan held to his man, knowing full well that, were his adversary to get the upper hand now, it would go hard with Dan Davis. Using their free hands, the men managed to pull themselves back into the boat.

By this time both were well-nigh exhausted. Their efforts were attended with little success compared with what they had done earlier in the battle. White was struggling to get his adversary overboard, while Dan was seeking to overcome the Hawaiian without doing him serious injury.

All at once the men stumbled over a seat. Dan fell prone upon the prostrate Black, with White on top of him. And there the gladiators lay, breathing hard, gasping for breath, half suffocated with the salt water that was dashing into their faces.

Everything about him seemed to Dan suddenly to grow blacker than before. He felt his head swimming.

"I'm going to faint," he gasped.

With one final supreme effort he threw the weight of White's body from him, and, rolling over, wrapped his arms about the Hawaiian, crushing the fellow down with all his strength.
