The man with whom Professor Maxon had grappled had no opportunity to use his weapons for the crazed man held him close with one encircling arm while he tore and struck at him with his free hand. The fourth Dyak danced around the two with raised parang watching for an opening that he might deliver a silencing blow upon the white man’s skull. The great odds against the two men—their bravery in the face of death, their grave danger—and last and greatest, the fact that one was the father of the beautiful creature he worshipped, wrought a sudden change in Number Thirteen. In an instant he forgot that he had come here to kill the white-haired man, and with a bound stood in the center of the room—an unarmed giant towering above the battling four. The parang of the Dyak who sought Professor Maxon’s life was already falling as a mighty hand grasped the wrist of the head hunter; but even then it was too late to more than lessen the weight of the blow, and the sharp edge of the blade bit deep into the forehead of the white man. As he sank to his knees his other antagonist freed an arm from the embrace which had pinioned it to his side, but before he could deal the professor a blow with the short knife that up to now he had been unable to use, Number Thirteen had hurled his man across the room and was upon him who menaced the scientist. Tearing him loose from his prey, he raised him far above his head and threw him heavily against the opposite wall, then he turned his attention toward Sing’s assailants. All that had so far saved the Chinaman from death was the fact that the two savages were each so anxious to secure his head for the verandah rafters of his own particular long-house that they interfered with one another in the consummation of their common desire. Although battling for his life, Sing had not failed to note the advent of the strange young giant, nor the part he had played in succoring the professor, so that it was with a feeling of relief that he saw the newcomer turn his attention toward those who were rapidly reducing the citadel of his own existence. The two Dyaks who sought the trophy which nature had set upon the Chinaman’s shoulders were so busily engaged with their victim that they knew nothing of the presence of Number Thirteen until a mighty hand seized each by the neck and they were raised bodily from the floor, shaken viciously for an instant, and then hurled to the opposite end of the room upon the bodies of the two who had preceded them.
