“Oh, I shouldn’t mind,” said the American, laughing. “Come on.”

Tom made a feint of climbing up, but there was another fierce blow at him, and all the while quite a battle was raging somewhere on deck, the sounds of blows and firing, with yells, oaths, and shrieks of agony reaching their ears in a confused murmur.

“Come on, Tom,” cried Mark, who was completely carried away by the excitement, and half maddened by the knowledge that if they could make a diversion, the schooner and its cargo might yet be saved.

“Right, sir,” cried Tom.

“Forward, then!”

Mark reached up, caught at the ornamental work of the stern, and in another moment would have drawn himself on deck, but the man struck a savage blow at him, and, as Mark threw himself sidewise to avoid the bar, one hand gave way, and in his efforts to save himself, the other followed, his feet seemed to be dragged from the ledge of the window upon which he stood, and he fell headlong. But he was checked, and the next moment found himself hanging head downwards, with his face pretty close to the murky water, in which he fancied he could see the broad shovel nose of a shark.

He fell no farther, for, quick as light, Tom had made a dash at him as he slipped, and managed to grasp one leg, which glided through his great, strong hand till he gripped it fast by the ankle.

“Hold on tight to me,” cried Tom, excitedly; and two men grasped him firmly as he hung over the window-ledge, supporting Mark suspended there, face downward, and just above the level of the sea.
