Na met him at the entrance. She was returning from a clump of trees a short distance away. Her arms were loaded with Manno, the fruit of Mars, and clusters of wild berries and grapes. "You see," she said, "I will make you a good mate. Our table will be well provided for." "You will make no mate at all," Ro said sternly, "and there will be no table if you wander off. Your next meeting with the Oan may not be so fortunate." He glared at her for a moment, then smiled and helped her with her burden. The others in the cave awakened. Ro noticed that Charlotte had slept beside Carlson, but moved away shyly now that it was daylight. He noticed, too, that Grimm was seeing the same thing and seemed annoyed. Ro smiled. These young white men were no different than Martians where a girl was concerned. When they had finished breakfast, they sat around the floor of the cave and spoke. It was Carlson who asked, "How do you expect the six of us to attack the rat men?" "The Oan are cowards," Ro answered. "They are brave only because they have your weapons. But now that you are free, you can make more of these sticks that shoot fire." Grimm laughed. "It takes intricate machinery to construct a ray gun," he said. "Here in this wilderness we have sticks and stones to work with." Ro sprang to his feet to tower above the man. His handsome face was twisted in anger. "You're lying," he shouted aloud, forgetting that the white man couldn't understand his words. "You're lying because you are afraid. You refuse to help me avenge my people because you are more of a coward than the Oan." Grimm climbed to his feet and backed away. Ro advanced on him, his fists clenched. The old man also rose. He placed a restraining hand on Ro's arm. "He's lying," said Ro with his thoughts. "Tell him I'm speaking the truth, professor," said Grimm aloud. The professor repeated Grimm's words with his thoughts. "It would be impossible to make new guns here," he said. "But there is another way. I have thought about it all night." Ro turned quickly. "What is it?" he demanded. "The space sphere. There are weapons on our ship that are greater than ray guns. With those we could defeat the rat men." The professor shrugged, turned away. "But how could we get into the ship? It is too well guarded." Ro fell silent. He walked to the mouth of the cave and stared out. When he turned back to the others, his attention was centered on Na. "Perhaps the attraction you seem to hold for the Oan can be put to good use," he said aloud. "The sphere is a distance away from the Oan camp. All of the rat men cannot be guarding it. Perhaps, by revealing yourself, you can lure the guards away from their post." He repeated his plan to the others. "But they'll kill her," gasped Charlotte. "She will be a woman alone," said Ro. "The Oan prefer to capture women when they can." "Then she'll be captured," the professor said. "It's much too risky." Ro laughed.
