that was unlike either Earth or the ship, a novel and exhilarating "Jack!" "You're all right, honey." She raised herself on her elbow and looked out through the unglazed window at the ordered streets of the great Luna Dome. "The Moon.... Jack, you did it!" Somehow, dizzily, she was at her seat, led there by a smiling, brown-clad stewardess and her azure-tipped fingers were clutching at the pearl-gray plasta-leather of the chair arm. Her eyes, the azure of her nails, the azure (so she had been told) of Earth seen from interplanetary space, grew hot. She closed them, and for a moment gave herself up to an almost physical yearning for the Toluca Lake it?" He hugged her. After a time he reached down and touched her swelling Stubbornly she forced herself back to reality. At any moment Jack, waist. It was like a benediction. "He'll be born on the Moon," he whispered, "and he'll have eyes the color of all Earth when it looks out to the stars." " She'll be born on the Moon," corrected Marcia, "and her name will be Sue, and ... and she'll be almost as good as her father." She turned her face away from the aisle, covered her cheek with her hand to hide it. Her gaze went out through the ray-proof glass port to the field, to the laboring beetle of a red tractor bearing the gangway that's so very normal .... Her numb lips moved. "I'm fine," she said. Miss Eagen (which, her neat lapel button attested, was her name) made a penciled frown as lovely as her machined smile. "Some day," she told Marcia, "we won't have to ask the passengers if they're well. It's so Jack would rise to the occasion, and it would be all right. she was just doing it to surprise Jack. He'd said it during the quarrel, and he'd roared at her, "And that's why you want me to come back—ground myself, be an Earth-lubber—so I in her had been pleased at the dull flush that rose to his face. Everyone knew about the cold that always seeped into the warm house when he talked about space, the Moon or crashing into it. And of course you're not listening." "It's all so dull!" she had flared, and then, "How can I be interested and made her fight back unfairly. After he'd gone—for good, he said—her anger had sustained her for a few weeks. Then, bleakly, she knew she'd go to the ends of Earth for Jack. Or even to the Moon.... different from being in an airplane. At the same time—" She paused, quiet brown eyes solemn. "What you are about to experience is something that will make you proud to belong to the human race." That but cold, ravening fear as the rumble heightened. She tried to close her eyes, her ears against it, but her mind wouldn't respond. She squirmed in her chair and found herself staring down at the field. It looked the way she felt—flat and pale and devoid of life, with a monstrous structure of terror squatting in it. The scene was abruptly splashed with a rushing sheet of flame that darkened the daytime sky. Then it was torn from her vision. It was snatched away—the buildings, the trees, the roads surrounding the field seemed to pour in upon it, shrinking as they ran together. Roads dried up like parched rivers, thinning and vanishing into the circle of her horrified vision. A great, soft, uniform weight pressed her down and back she fought it, but it was too big and too soft. Now Earth's surface was vague and Sun-splashed. Marcia's sense of loss tore at her. She put up her hands, heavily, and pressed the glass as if she could push it out, push herself out, go back, back to Earth and solidity. Clouds shot by like bullets, fell away until they were snowflakes roiling in violet haze. Then, in the purling universe that had grown around the ship, Earth was a mystic circle, a shallow dish floating darkly and heavily below. paid more attention to Jack's ramblings about orbits and turn-over points and correction blasts, and all that gobbledegook. She glanced outside again and the sky was no longer deep blue, but black. She pressed herself up out of the soft chair—it was difficult, because of the one-and-a-half gravities the ship was holding—and plodded heavily "I'm Mrs. McHenry. I'm Jack's wife." "I'm pregnant, Jack," she said. She put out a hand to ward him off. She There was no describable change in his face, but the taut skin of his space-tanned cheek seemed, somehow, to draw inward. His eyebrow ridges seemed to be more prominent, and he looked older, and very tired. Softly and slowly he asked, "What in God's name made you get on the no matter how he felt about them before." The stewardess looked at her, her face registering a strange mixture of detachment and wonder. "You really believe that, don't you?" husband, and don't you forget "And why not?" "Because," said Miss Eagen, and in that moment she looked almost as all times no matter what. If I have feelings at all, part of my job is to the rules. Jaywalkers. But out here jaywalkers don't have as much margin for error as they do crossing against a traffic light on Earth." She looked Marcia straight in the eye. "What makes a jaywalker isn't ignorance. It's a combination of stupidity and stubbornness. The jaywalker does "So now Jack will spin the ship until I'm pressed against the walls "You mean, but why doesn't he just work the ship while it's spinning "He'll spin the ship on its long axis," said the stewardess with hurt and hatred—hatred of the stars, of this knowledgeable, inspired girl, and—even more so—of herself. She darted toward the door. "He will and he must. You surely know your husband." She found herself at the entrance to the pilot room. In one sweeping glance she saw a curved, silver board. Before it a man sat tranquilly. Nearer to her was Jack, hunched over the keyboard of a complex, compact Her lips formed his name, but she was silent. She watched him, his square, competent hands, his detached and distant face. Through the forward view-plate she saw a harsh, jagged line, the very edge of the Moon's disc. Next to it, and below, was the rear viewer, holding the shimmering azure shape of Earth. " All Earth watches me when I work, but with your eyes. " Jack had said that to her once, long ago, when he still loved her. "Yes, I know who Jack's spinning the ship for," said Marcia. Elsinore . He's astonishment, "Hurt? Oh, no! It's so—so big!" There was a sudden thunder. Over Miss Eagen's shoulder, through the port, Marcia saw the stars begin to move. Miss Eagen followed her gaze. stars, the Moon and Sue Eagen danced and wove. Words slipped in and out of it like shreds of melody: "A man comes to love the things he has to fight for." And Jack Sue Eagen was there, too, and the thing she shared with Jack. Of course there was something between them—so big a thing that there was nothing for her to fear in it. that he had loved and married. There was a long time of blackness, and then a time of agony, when she was falling, falling, and her lungs wanted to split, explode, and then a long, deep sleep. A curved ceiling, but a new curve, and soft rose instead of the gunmetal-and-chrome of the ship. White sheets, a new feeling of "down"
