<passage>:
STRANGER FROM SPACE She prayed that a God would come from the skies and carry her away to bright adventures. But It was twilight on Venus—the rusty red that the eyes notice when gigantic child. There was no sign of clear sky and stars—the heavens Venusian speech, "How I envy you, Koroby! I wish I were being married She left them, moving gracefully to the door. Venus-girls were had to strain forward to hear her. "I wish that there were other worlds than this—and that someone would drop out of the skies and claim "Well—heigh-ho! There don't seem to be any other worlds, and nobody is going to steal me away from Yasak, so I might as well get on with my preparations. The men with the litter will be here soon to carry me to He would come ... the man of my dreams!" Then she turned and stepped out into the night. "This way," the litter-carrier announced, touching the girl's arm. They stumbled over the rutted clearing toward the twinkling sparks that were the lights of the other litter-bearers, colored sparks as befitted like a cloak of light. At times a breeze would shake the ceiling of the litter seemed to float along—none of the bearers even stumbled. They came to a cleared space of waist-high grass. It was like a canyon steeply walled by cliffs of verdure. The litter jerked as it glided along, and Koroby heard one of the bearers exclaim gruffly, "Listen!" Then the litter resumed its dream-like floating on the backs of the men. "Thought I heard something," the other replied. "Shrill and high—like something screaming—" certainly not thunder—unlike any sound that Koroby had ever heard. There was a babble of voices as the musicians crowded together, asking what had it been, and where—just exactly—could one suppose it had happened, that thunder—was it going to storm! They waited, but nothing further happened—there were no more stabs of His face swung up to hers. "But—there's no path that way—" "I don't care," she said. "Take me there." Her order had reached the others' ears, and they slowed their pace. "Lady—believe me—it's impossible. There's nothing but matted jungle in that direction—we'd have to hack our way as we go along. And who knows how far away that light is? Besides, you're on your way to be married." "Take me to that light!" she persisted. They set the litter down. "We can't do that," one man said to another. "You'd better," she said ominously. "Otherwise, I'll make a complaint to Yasak—" "You can't do that!" a carrier cried. "Well, then, you take me," she said over her shoulder. Grumbling, they bent to the conveyance's poles, and Koroby lithely slipped to the cushions. They turned off the path, plodded through the deep grass toward the light. The litter lurched violently as their feet caught in the tangled grass, and clouds of fine dust arose from the disturbed blades. By the time they reached the source of the light, they were quite demoralized. The musicians had not accompanied them, preferring to carry the message to Yasak in the Stone City that his prospective they had abandoned the litter finally. Her blue drapery was ripped and rumpled her carefully-arranged braids had fallen loose dust on her face had hid its youthful color, aging her. The expedition emerged from the jungle on a sandy stretch of barren land. A thousand feet away a gigantic metal object lay on the sand, crumpled as though it had dropped from a great distance. It had been globular before the crash, and was pierced with holes like windows. sky— Koroby hastily grasped a corner of her gown, moistened it with saliva, Even his feet were covered. Perhaps it was armor—though the Venus-men And maybe more And though we'll neither speak, We'll know the score—" Venus!" he said slowly. "No name? But who are you? Where are you from? And what is that?" She "The vehicle by which I came here from a land beyond the sky," he said. She had no concept of stars or space, and he could not fully explain. "From a world known as Terra." asked, "Is it far? Have you come to take me there?" Here the similarity between her dream and actual experience ended. What was he thinking as he eyed her for a long moment? She had no way of guessing. He said, "No, I am not going to take you back there." Her month gaped in surprise, and he continued, "As for the distance to Terra—it is incredibly far away." said, "But if it is so far away, how could you speak my language? There We are concerned with more weighty things than our own selves. But I have a personal problem now," he said, making a peculiar sound that was not quite a sigh. "Here I am stranded on Venus, my ship utterly wrecked, and I'm due at the Reisezek Convention in two weeks. You"—he gripped Koroby's shoulder, and his strength made her wince—"tell me, by now had died to a fitful glimmer. Then the stranger and the girl started toward the jungle, where the litter-bearers awaited them. As the party was struggling through the prairie's tall grass, the man "Call me Robert. It is an ancient name on Terra." because she wanted to impress this indifferent man that she was not as inferior as he might think—but now she could not go on. With a little cry almost of relief, she sank to the ground and lay semi-conscious, so weary that the very pain of it seemed on the point of pleasure. Robert dipped down, scooped her up, and carried her. Lights glimmered ahead shouts reached them. It was a searching party, "Yasak's out somewhere. The stranger man is in the room at the end of "Thank you for carrying me, Robert." He did not reply. "Robert—I dreamed of you last night. I dreamed you built another round house and that we both flew away in it. Yasak had to stay behind, and he was furious. Robert! Aren't you listening?" "I hear you." sprang at him. "You'll hurt yourself," he admonished kindly, and after she had pummeled his chest, bruising her fingers on his armor, she turned away. "And now if you're through playing your incomprehensible little scene," emotions—I was never allowed them. But it is an esthetic regret.... I must go back to my wrecked ship now and arrange the signals there." He —a firestone. Then she slipped outside and down the street. The City's wall was not far behind. Robert was visible in the distance, striding toward his sky-ship, a widening cloud of dust rising behind him like the spreading wake of a boat. Koroby stood on tip-toe, waving and calling after him, "Robert! Robert! Come back!" but he did not seem to hear. crowd. Someone grasped her roughly—she was too breathless to do more than gasp for air—and shook her violently. "You fool, you utter difficult to breathe, and ashes were drifting lightly down like dove-colored snow. Yasak, watery eyed, a cloth pressed to his nose, was walking with several others over the smoking earth and still warm ashes up to his knees. In one hand he held a stick. He stopped and pointed. "He fell about here," he said, and began to probe the ashes with the stick. He struck something. "Here he is!" he cried. The others hurried to the spot and scooped ashes away, dog-fashion, until Robert's remains were laid clear. There were exclamations of amazement and perplexity from the people.
