Upon the flat surface of the ledge, which comprised some two acres, were congregated fully a hundred men, women and children. All eyes were turned in their direction as they came into view and on sight of Tarzan the warriors sprang to their feet, seizing spears and knives. The women called their children to them and moved quickly toward the entrance to the cavern. "Do not fear," cried the boy. "It is only Ovan and his friend, Tarzan." "We kill," growled some of the warriors. "Where is Avan the chief?" demanded the boy. "Here is Avan the chief," announced a deep gruff voice, and Tarzan shifted his gaze to the figure of a stalwart, brawny savage emerging from the mouth of the cavern. "What have you there, Ovan?" demanded the chief. "If you have brought a prisoner of war, you should have disarmed him first." "He is no prisoner," replied Ovan. "He is a stranger in Pellucidar and he comes as a friend and not as an enemy." "He is a stranger," replied Avan, "and you should have killed him. He has learned the way to the caverns of Clovi and if we do not kill him he will return to his people and lead them against us." "He has no people and he does not know how to return to his own country," said the boy. "Then he does not speak true words, for that is not possible," said Avan. "There can be no man who does not know the way to his own country. Come! Stand aside, Ovan, while I destroy him." The lad drew himself stiffly erect in front of Tarzan. "Who would kill the friend of Ovan," he said, "must first kill Ovan." A tall warrior, standing near the chief, laid his hand upon Avan's arm. "Ovan has always been a good boy," he said. "There is none in Clovi near his age whose words are as full of wisdom as his. If he says that this stranger is his friend and if he does not wish us to kill him, he must have a reason and we should listen to him before we decide to destroy the stranger." "Very well," said the chief; "perhaps you are right, Ulan. We shall see. Speak, boy, and tell us why we should not kill the stranger." "Because at the risk of his life he saved mine. Hand to hand he fought with a great ryth from which I could not have escaped had it not been for him; nor did he offer to harm me, and what enemy of the Clovi is there, even among the people of Zoram or Daroz who are of our own blood, that would not slay a Clovi youth who was so soon to become a warrior? Not only is he very brave, but he is a great hunter. It would be well for the tribe of Clovi if he came to live with us as a friend." Avan bowed his head in thought. "When Carb returns we shall call a council and decide what to do," he said. "In the meantime the stranger must remain here as a prisoner." "I shall not remain as a prisoner," said Tarzan. "I came as a friend and I shall remain as a friend, or I shall not remain at all."
