No vocal sound came from the votaries, but hissing intake of breath sucked through thick lips, and the rows of black bodies swayed like reeds in the wind. The great ape leaped up, his face a slavering devil's mask; he howled with frightful eagerness, gnashing his great fangs, that yearned to sink into that soft white flesh, and the hot blood beneath. He surged against his chain, and the stout post quivered. McGrath, in the bushes, stood frozen, paralyzed by the imminence of horror. And then John De Albor stepped behind the unresisting girl and gave her a powerful push that sent her reeling forward to pitch headlong on the ground under the monster's talons. And simultaneously McGrath moved. His move was instinctive rather than conscious. His .44 jumped into his hand and spoke, and the great ape screamed like a man death-stricken and reeled, clapping misshapen hands to its head. An instant the throng crouched frozen, white eyes bulging, jaws hanging slack. Then before any could move, the ape, blood gushing from his head, wheeled, seized the chain in both hands and snapped it with a wrench that twisted the heavy links apart as if they had been paper. John De Albor stood directly before the mad brute, paralyzed in his tracks. Zemba roared and leaped, and the African went down under him, disemboweled by the razor-like talons, his head crushed to a crimson pulp by a sweep of the great paw. Ravening, the monster charged among the votaries, clawing and ripping and smiting, screaming intolerably. Zambebwei spoke, and death was in his bellowing. Screaming, howling, fighting, the black people scrambled over one another in their mad flight. Men and women went down under those shearing talons, were dismembered by those gnashing fangs. It was a red drama of the primitive--destruction amuck and ariot, the primordial embodied in fangs and talons, gone mad and plunging in slaughter. Blood and brains deluged the earth, black bodies and limbs and fragments of bodies littered the moonlighted glade in ghastly heaps before the last of the howling wretches found refuge among the trees. The sounds of their blundering, panic-stricken flight drifted back. * * * * * McGrath had leaped from his covert almost as soon as he had fired. Unnoticed by the terrified negroes, and himself scarcely cognizant of the slaughter raging around him, he raced across the glade toward the pitiful white figure that lay limply beside the iron-bound stake. "Constance!" he cried, gathering her to his breast. Languidly she opened her cloudy eyes. He held her close, heedless of the screams and devastation surging about them. Slowly recognition grew in those lovely eyes. "Bristol!" she murmured, incoherently. Then she screamed, clung to him, sobbing hysterically. "Bristol! They told me you were dead! The blacks! The horrible blacks! They're going to kill me! They were going to kill De Albor too, but he promised to sacrifice----"
