Once or twice the girl glimpsed another such monster as her captor. Evidently they had gone far beyond the vaguely defined boundaries of her race. The other Neandertal men avoided them. It was evident that they lived as do beasts, uniting only against some common enemy and not often then. Therein had lain the reason for the success of the Cro-Magnons' warfare against them.
Into a ravine he carried the girl, and into a cave, small and vaguely illumined by the light from without. He threw her roughly to the floor of the cave, where she lay, too terrified to rise.
The monster watched her, like some demon of the forest. He did not even jabber at her, as an ape would have done. The Neandertalers had no form of speech whatever.
He offered her meat of some kind—uncooked, of course. Her mind reeling with horror, she saw that it was the arm of a Cro-Magnon child. When he saw she would not eat, he devoured it himself, tearing the flesh with great fangs.
He took her between his great hands, bruising her soft flesh. He ran rough fingers through her hair, and when he saw that he hurt her he seemed filled with a fiendish glee. He tore out handfuls of her hair, seeming to enjoy devilishly the torturing of his fair captive. A-aea set her teeth and would not scream as she had done at first, and presently he desisted.
The leopard-skin garment she wore seemed to enrage him. The leopard was his hereditary foe. He plucked it from her and tore it to pieces.
And meanwhile Ga-nor was hurrying through the forest. He was racing now, and his face was a devil's mask, for he had come upon the bloody glade and found the monster's tracks, leading away from it.
And in the cave in the ravine the Neandertaler reached for A-aea.
She sprang back and he plunged toward her. He had her in a corner but she slipped under his arm and sprang away. He was still between her and the outside of the cave.
Unless she could get past him, he would corner her and seize her. So she pretended to spring to one side. The Neandertaler lumbered in that direction, and quick as a cat she sprang the other way and darted past him, out into the ravine.
With a bellow he charged after her. A stone rolled beneath her foot, flinging her headlong; before she could rise, his hand seized her shoulder. As he dragged her into the cave, she screamed, wildly, frenziedly, with no hope of rescue, just the scream of a woman in the grasp of a beast.
Ga-nor heard that scream as he bounded down into the ravine. He approached the cave swiftly but cautiously. As he looked in, he saw red rage. In the vague light of the cave, the great Neandertaler stood, his piggish eyes on his foe, hideous, hairy, blood-smeared, while at his feet, her soft white body contrasting with the shaggy monster, her long hair gripped in his blood-stained hand, lay A-aea.
The Neandertaler bellowed, dropped his captive and charged. And Ga-nor met him, not matching brute strength with his lesser might, but leaping back and out of the cave. His spear leaped and the monster bellowed as it tore through his arm. Leaping back again, the warrior jerked his spear and crouched. Again the Neandertaler rushed, and again the warrior leaped away and thrust, this time for the great hairy chest. And so they battled, speed and intelligence against brute strength and savagery.
Once the great, lashing arm of the monster caught Ga-nor upon the shoulder and hurled him a dozen feet away, rendering that arm nearly useless for a time. The Neandertaler bounded after him, but Ga-nor flung himself to one side and leaped to his feet. Again and again his spear drew blood, but apparently it seemed only to enrage the monster.
Then before the warrior knew it, the wall of the ravine was at his back and he heard A-aea shriek as the monster rushed in. The spear was torn from his hand and he was in the grasp of his foe. The great arms encircled his neck and shoulders, the great fangs sought his throat. He thrust his elbow under the retreating chin of his antagonist, and with his free hand struck the hideous face again and again; blows that would have felled an ordinary man but which the Neandertal beast did not even notice.
Ga-nor felt consciousness going from him. The terrific arms were crushing him, threatening to break his neck. Over the shoulder of his foe he saw the girl approaching with a great stone, and he tried to motion her back.
With a great effort he reached down over the monster's arm and found his ax. But so close were they clinched together that he could not draw it. The Neandertal man set himself to break his foe to pieces as one breaks a stick. But Ga-nor's elbow was thrust under his chin, and the more the Neandertal man tugged, the deeper drove the elbow into this hairy throat. Presently he realized that fact and flung Ga-nor away from him. As he did so, the warrior drew his ax, and striking with the fury of desperation, clove the monster's head.
