One of the voices mourned, in the twittering Venusian speech, "How I envy you, Koroby! I wish I were being married Koroby stared defiantly at the laughing faces of her bridesmaids. She shrugged hopelessly. "I don't care," she said slowly. "It will be nice to have Yasak for a husband—yes. And perhaps I do love him. I don't know." She tightened her lips as she reflected on it. She left them, moving gracefully to the door. Venus-girls were seemed incapable of the slightest exertion. But Koroby's body She rested against the door-frame, watching the red of the afterglow deepen to purple. "I want romance," she said, so softly that the girls 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 the head of the kneeling one. She eyed herself in the mirror. "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.

Her lips moved in the barest murmur: "If only—!" and again, "Oh, if only—!" But the music trickled on, and nothing along, and Koroby heard one of the bearers exclaim gruffly, "Listen!" Koroby peered out. "A Koroby lifted a hand. "Stop the litter," she said. The conveyance halted.

"Shall we go on?" one of them asked Koroby. shining steadily, green as the flashes had been. Noticing it, Koroby Suddenly Koroby reached out, tapped the shoulder of the closet bearer. knows how far away that light is? Besides, you're on your way to be married." Koroby stepped out to the path, straightened up, her eyes on the glow. "You'd better," she said ominously. "Otherwise, I'll make a complaint to Yasak—" The men eyed each other, mentally shrugging. "Well—" one yielded. The girl whirled impatiently on the others. "Hurry!" she cried. "If you won't take me, I'll go by myself. I must get to that fire, whatever it is!" She put a hand to her heart. "I must! I must!" Then she faced the green glare again, smiling to herself. Grumbling, they bent to the conveyance's poles, and Koroby lithely 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 were exhausted and panting.

The But Koroby, with supreme confidence, walked toward the stranger, her to the man's side and gently touched him again. He turned, and her heart faltered: she swayed with bliss.

Here was a face so finely-chiseled, so perfectly proportioned, that it was The stranger did not speak, merely gazed deeply into Koroby's eyes. And she, returning the gaze, wondered if he was peering into her very soul. The words of a folk-ballad came to her: Koroby watched him, forgot her fear, and went eagerly to him, took his whisper. They watched the melting globe sag on the sand. Then Koroby Koroby cut him short. "What's your name?" gripped Koroby's shoulder, and his strength made her wince—"tell me, He handed the stick to Koroby, but she was afraid to touch it. This was But at last she could go no farther. She had forced herself along 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 had happened. "A green light—loud sounds—fire—this man there—" and "It makes no difference," Robert said. "You will stay with me while you are in the City, of course," Yasak "Yasak's out somewhere. The stranger man is in the room at the end of the hall." "Fetch me something to wear—that's good enough," the girl accepted the mantle offered by the slave. "Quick, some water—I must wash." furious. Robert! Aren't you listening?" afraid I haven't any use for it. Where I come from there is no love, and there shouldn't be here, either. It's a waste of time." She stepped back from him, clenching her hands. "Oh, I hate you—hate you! You don't care the least bit about me—and I've shamed myself in front of you—I, supposed to be Yasak's wife by now!" She began to cry, hid her face in suddenly lax fingers. She looked up fiercely. "I could kill you!" Robert stood immobile, no trace of feeling marring the sprang at him.

The flames rose in a monstrous Koroby reached the City wall, panted through the gate into a shrieking than gasp for air—and shook her violently. "You fool, you utter fool! What did you think you were doing?" Others clamored around her, reaching for her. Then she heard Yasak's voice. Face stern, he pushed through the crowd, pressed her to him. "Let her alone—Let her alone, I say!" They watched the conflagration, Yasak and Koroby, from a higher part of now and then. He was running, trying to outrace the flames. Then they difficult to breathe, and ashes were drifting lightly down like dove-colored snow. Yasak, watery eyed, a cloth pressed to his nose, was "Magic!" someone cried, and backed away.
