Wolf entered the glade, and noted where the footsteps of the girl and those of a man came together. For a moment or two he appeared troubled and suspicious; then his face cleared. He saw that the tracks had diverged again. He had recognized the man's tracks as those of Yellow Hair.
"Yellow Hair is afraid of my strong arm," he thought. "He dare not stay with Red Lips. I shall catch her soon and beat her and take her with me."
The two crouching upon the precipice watched his every movement. They had rolled to the edge of the declivity a rock as huge as they could control, and now together held it poised over the pathway. Wolf came hurrying along, his head bent down like that of a hound on the scent of game. He reached a spot just beneath the two, and then with a sudden united effort they shoved over the rock. It thundered down upon the unfortunate Wolf with an accuracy which spoke well for the eyes and hands of the lovers. The man was crushed horribly. The two above scrambled down, laughing, and Yellow Hair took from the dead Wolf a necklace of claws and fastened it proudly upon his own person.
"Now we will go to my cave," said he.
"No," said Red Lips; "my father will look for Wolf to-morrow, and will find him. Then he will come and kill us. We must go and kill him to-night."
"Yes," said Yellow Hair.
Hand in hand the two started for the cave of Fangs. The side hill in which it was situated was very steep, and the lovers thought they could duplicate the affair with Wolf. "We must cripple him, anyway," said Yellow Hair, "for I am not strong enough to fight him alone. His club is heavy."
They reached the vicinity of the cave and crept above it. Having, with great difficulty, secured a rock in position to be rolled down, they waited for Fangs to appear. He came out about dusk, and stretched out his arms lazily, when the two above released the rock. It rolled down swiftly and with great force, but there was no such sheer drop afforded as when Wolf was killed, and Fangs heard the stone coming and almost eluded it. It caught one of his legs, as he tried to leap aside, and broke it. Fangs fell to the ground.
With a yell of triumph Yellow Hair bounded to where the crippled man lay and began pounding him upon the head with his club. Fangs had a very thick head. He struggled vigorously, and succeeded in catching Yellow Hair by the wrist. Then he drew the younger man to him and began to throttle him. The case of Yellow Hair was desperate. Fangs's great strength was too much for him. His stifled yells told of his agony.
It was at this juncture that Red Lips demonstrated her quality as a girl of decision and of action. A sharp fragment of slate, several pounds in weight, lay at her feet. She seized it and bounded forward to where the struggle was going on. The back of Fangs's head was fairly exposed. The girl brought down the sharp stone upon it just where the head and spinal column joined, and the crashing thud told of the force of the blow. Delivered with such strength upon such a spot there could be but one result. The man could not have been killed more quickly. Yellow Hair released himself from the dead giant's embrace and rose to his feet. Then, after a short breathing time, to make assurance sure, he picked up his club and battered the head of Fangs until there could be no chance of his resuscitation. The performance was unnecessary, but neither Yellow Hair nor Red Lips was aware of the fact. Their knowledge of anatomy was limited. Neither knew the effect of such a blow delivered properly at the base of the brain.
