Joe shrugged. It hurt. "Powder metallurgy? Yes, I've seen it used, at my father's plant. They've made small precision parts with it. Why?" "D'you know if anybody ever made a weld with it?" asked Mike. Joe chewed. Then he said: "I think so. Yes. At the plant they did. They had trouble getting the surfaces properly cleaned for welding. But they managed it. Why?" "One more question," said Mike tensely. "How much Portland cement is used to make a cubic yard of concrete?" "I wouldn't know," admitted Joe. "Why? What's all this about?" "Haney and the Chief. Those two big apes have been kidding me--as long as they could stay awake--for what happened to me when I landed. Those infernal savages--" Mike seethed. "They got my clothes off and they had me smeared all over with butter and forty-'leven necklaces around my neck and flowers in my hair! They thought I was some kind of heathen god! Hanuman, somebody told me. The Hindu monkey-god!" He raged. "And those two big apes think it's funny! Joe, I never knew I _knew_ all the words for the cussings I gave those heathen before our fellas found me! And Haney and the Chief will drive me crazy if I can't slap 'em down! Powder metallurgy does the trick, from what you told me. That's okay, then." He stood up and stalked toward the front of the plane. Joe roused himself with an effort. He turned to look about him. Haney lay slumped in a reclining chair, on the other side of the plane cabin. His eyes were closed. The Chief lay limply in another chair. He smiled faintly at Joe, but he didn't try to talk. He was too tired. The return to normal gravity bothered him, as it did Joe. Joe looked out the window. In neat, geometric spacing on either side of the transport there were fighter jets. There was another flight above and farther away. Joe saw, suddenly, a peeling-off of planes from the farther formation. They dived down through the clouds. He never knew what they went to look for or what they found. He went groggily back to his bunk in a strange and embarrassing weakness. He woke when the plane landed. He didn't know where it might be. It was, he knew, an island. He could see the wide, sun-baked white of the runways. He could see sea-birds in clouds over at the edge. The plane trundled and lurched slowly to a stop. A service-truck came growling up, and somebody led cables from it up into the engines. Somebody watched dials, and waved a hand. There was silence. There was stillness. Joe heard voices and footsteps. Presently he heard the dull booming of surf. The plane seemed to wait for a very long time. Then there was a faint, faint distant whine of jets, and a plane came from the east. It was first a dot and then a vague shape, and then an infinitely graceful dark object which swooped down and landed at the other end of the strip. It came taxiing up alongside the transport ship and stopped.
