goals of today were as incomprehensible as the ancient quest for the Holy Grail! Despite his sudden irrational anger toward her, Maitland tried to stick There was a thump. Maitland stirred, came half awake, and opened his the open window fell on the foot of his bed. Outside, the residential section of the Reservation slept silently under the pale illumination of the full Moon. He guessed sleepily that it was about three o'clock. What had he heard? He had a definite impression that the sound had come from within the room. It had sounded like someone stumbling into a chair, or— Something moved in the darkness on the other side of the room. Maitland started to sit up and it was as though a thousand volts had shorted his brain.... This time, he awoke more normally. He opened his eyes, looked through the window at a section of azure sky, listened to the singing of birds somewhere outside. A beautiful day. In the middle of the process of stretching his rested muscles, arms extended back, legs tensed, he froze, looking up—for the first time really seeing the ceiling. He turned his head, then rolled off the bed, wide awake. This wasn't his room! plant ought to have been, a river wound across the scene, almost hidden beneath its leafy roof of huge ancient trees. Shock contracted Maitland's diaphragm and spread through his body. His breathing quickened. Now he remembered what had happened during the night, the sound in the darkness, the dimly seen figure, and then—what? Blackout.... Where was he? Who had brought him here? For what purpose? He thought he knew the answer to the last of those questions. As He pivoted to inspect the room. Even before his eyes could take in the details, he had the impression that there was something wrong eyes. The room was dark except where a broad shaft of moonlight from the door slid aside and disappeared. Maitland glanced in at Maitland stared at her, his face blank. His mind had just manufactured Maitland looked up at the girl, who was regarding him silently with He looked out at the peaceful vista of river and prairie. The character of the sunlight seemed to indicate that it was afternoon. He became aware that he was hungry. Where the devil could this place be? And—muscles tightened about his empty stomach—what was in store for him here? He stood trembling, acutely conscious that he was afraid and helpless, As they came closer, he saw that both of them had dark uniform suntans and showed striking muscular development, like persons who had trained for years with weights. They vanished below his field of view, presumably into the building. He sat down on the edge of the cot and glared helplessly at the floor. About half an hour later, the door he couldn't open slid aside into the wall. The man Maitland had seen outside, now clad in gray trunks and The fellow looked about forty-five. The first details Maitland noticed were the forehead, which was quite broad, and the calm, clear eyes. The dark hair, white at the temples, was combed back, still damp from "What's the idea?" Maitland asked. "What is all this?" Maitland stood there for a moment, deliberately relaxing his tensed Maitland shook his head stubbornly. the cot. When he was able to breathe again, there were straps across his chest, hips, knees, ankles, and arms, and Swarts was tightening a clamp that held his head immovable. Something eager leaped in Maitland's breast at the abrupt question, and expectancy. Maitland sighed and said, "Hello," then glanced down Later, when he had finished the steak and corn on the cob and shredded carrots, and a feeling of warm well-being was diffusing from his stomach to his extremities, he sat down on the bed to watch the sunset and to think. There were three questions for which he required answers before he Something icy settled on the back of his neck, ran down his spine, and diffused into his body. He stared at the planet unbelievingly, fists clenched, forgetting to breathe. He realized the truth in that moment. Later, when that jewel of a planet had set and the stars were out, he lay on the bed, still warm with excitement and relief. He didn't have to worry any more about military secrets, or who Swarts was. Those questions were irrelevant now. And now he could accept the Only one question of importance remained: What year was this? He grimaced in the darkness, an involuntary muscular expression of jubilation and excitement. The future "I'm adaptable," he told himself gleefully. "I can learn fast. There'll be a job for me out there...." If— Suddenly sobered, he rolled over and put his feet on the floor, sat in the darkness thinking. Tomorrow. Tomorrow he would have to find a way of breaking down Swarts' reticence. He would have to make the man but— After a while Maitland smiled to himself and went back to bed. He woke in the morning with someone gently shaking his shoulder. He rolled over and looked up at the girl who had brought him his meal the evening before. There was a tray on the table and he sniffed the smell that she had discarded the white cloak. As he swung his legs to the floor, she started toward the door, "Come on," Swarts said patiently, "let's get going. We have a lot to get through this morning." "I 3 x dx" in his head. It was a calculation which required great concentration and frequent tracing back of steps. After several minutes, he noticed that Swarts had stopped calling words. He opened his eyes to find the other man standing over him, looking somewhat exasperated and a little baffled. powder—then blackness. With a deliberate effort, Maitland unclenched his fists and tried to slow his breathing. Some kind of emotional reaction test—what was the countermove? He closed his eyes, but shortly the muscles around them declared excruciatingly that they couldn't keep that up. Maitland gritted his teeth and fought to use his brain then he had it. He thought of a fat slob of a bully who had beaten him up one day Swarts in standing by his silly rules and not telling him about this new world. Within a minute, he was in an ungovernable rage. His muscles tightened against the restraining straps. He panted, sweat came out on his forehead, and he began to curse. Swarts! How he hated.... There was blood hammering in Maitland's temples. His face felt hot and swollen and he writhed against the restraint of the straps. him for a few seconds, then relaxed and smiled weakly. His head was starting to ache from the effort of blinking. "What year is this?" he asked. Maitland's smile became a grin. That evening, he could hardly wait for her to come. Too excited to sit and watch the sunset, he paced interminably about the room, sometimes whistling nervously, snapping his fingers, sitting down and jittering one leg. After a while he noticed that he was whistling the same theme over and over: a minute's thought identified it as that exuberant mounting phrase which recurs in the finale of Beethoven's Ninth Symphony. He forgot about it and went on whistling. He was picturing himself irritated as he was this noon." Maitland urged her into the chair and sat down on the edge of the bed. that right?" She nodded apprehensively. "I have never heard of it being done." He sank down on the bed and put his face in his hands. After a while he his life to get to Mars. I thought I would in my time. I was positive I would when I knew I was in your time. And now I know I never will." The cot creaked beside him and he felt a soft arm about his shoulders and fingers delicately stroking his brow. Presently he opened his eyes and looked at her. "I just don't understand," he said. "It seemed
