Its nose was buried in the turf, folded back like an accordion. It had burst open like a ripe watermelon. He was surprised that he had survived at all. He scratched his head. "I was running from Mars to Jupiter with a load of seed for the colonists." He shook his head. "No," he reassured her. "I left him on Mars. He had an attack of space sickness. I was all by myself that was the that pretty women didn't upset him so. He said nervously, "Where am I? I couldn't have slept all the way to Jupiter." The girl shrugged her shoulders. "I don't know." "You don't know!" He almost forgot his self-consciousness in his surprise. His pale blue eyes returned to the landscape. A mile across foremost over the edge. Jonathan tumbled after her. He hit the bottom, winced, scrambled to his feet. The girl started at a trot for the hills. Jonathan, groaning at each step, hobbled beside her. "Why won't the Centaurs follow us into the hills?" he panted. "Hold on," he said. He felt in his pockets, withdrew an empty cigarette package, crumpled it and hurled it to the ground. Jonathan turned around, started back for the space ship. "Where are you going?" cried Ann in alarm. "No!" She clutched his arm. He was surprised at the strength of her grip. "They'd kill you," she said. "I can sneak back," he insisted stubbornly. "They might loot the ship. I don't want to lose those cigarettes. I was hauling some good burley tobacco seed too. The colonists were going to experiment with it on "We are going to the camp," she said. Jonathan threw himself down backwards, kicked the girl's feet out from under her. Like a cat he scrambled up and wrenched the spear away. warily. Ann Clotilde cried in anguish: "Don't let him get away!" Jonathan chose the centaurs. He wheeled around, dashed back the way he had come. Someone tackled him. He rolled on the rocky floor of the Jonathan was game, but the nine husky amazons pinned him down by sheer " He recognized it as a popular song of three years ago. Jonathan had never been so humiliated in his life. He was known in the He said, "Put me down. I'll walk." "You won't try to get away?" said Ann. "No," he replied with as much dignity as he could summon while being held aloft by four barbarous young women. "Let him down," said Ann. "We can catch him, anyway, if he makes a break." with which they had carried him. He was six feet three and no light weight. He thought enviously of the centaurs, free to gallop across the plains. He wished he was a centaur. The trail left the canyon, struggled up the precipitate walls. Jonathan picked his way gingerly, hugged the rock. "Don't be afraid," advised one of his captors. "Just don't look down." "I'm not afraid," said Jonathan hotly. To prove it he trod the narrow ledge with scorn. His foot struck a pebble. Both feet went out from under him. He slithered halfway over the edge. For one sickening moment Jonathan mistook them for horses. Then he saw that from the withers up resumed their march. Jonathan scrambled up hills, skidded down slopes. ordeal. He would have sat down and refused to budge except that he knew the girls would hoist him on their shoulders and bear him into the camp reappeared. He imagined that it had crashed into the mountain, skidded and rolled down its side until it lodged beside the stream. It reminded looked away hastily. Someone hailed them from the space ship. "We've caught a man," shrieked one of his captors. A flock of girls streamed out of the wrecked space ship. a captive princess. All the confidence engendered by the familiar settings of the space ship went out of him like wind. He, Jonathan Fawkes, was a castaway on an asteroid inhabited by twenty-seven wild bone. "Heaven forbid," he said. "How about coming with me to gather fruit?" cried the green-eyed blonde "you great big handsome man." rest." She turned to Jonathan who had shrunk down in his chair. "How "Is there any chance of patching it up?" He considered the question. More than anything else, he decided, he wanted to sleep. "What?" he said. movement pulled his muscles like a rack. Furthermore, an overpowering lassitude was threatening to pop him off to sleep before their eyes. Jonathan dragged himself back from the edge of sleep. "Just tired," he it was only by the most painful effort that he kept awake at all. His eyelids drooped lower and lower. At these words, Jonathan raised upright as if someone had pulled a rope. "and I'll make me another pair out of your hides. They set me back a week's salary." Having delivered himself of this ultimatum, he went back to sleep. The next day found Jonathan Fawkes hobbling around by the aid of a cane. At the portal of the space ship, he stuck out his head, glanced all around warily. None of the girls were in sight. They had, he presumed, gone about their chores: hunting, fishing, gathering fruits and berries. He emerged all the way and set out for the creek. He walked with an exaggerated limp just in case any of them should be hanging around. As long as he was an invalid he was safe, he hoped. off in cavalier fashion. He hobbled to the creek, sat down beneath the shade of a tree. He just wasn't the type, he supposed. And it might be years before they were rescued. As a last resort, he supposed, he could hide out in the hills or join the centaurs. He rather fancied himself galloping across the plains Jonathan put his arm around her gingerly. "Ouch!" He winced. He had forgotten his sore muscles. Jonathan leaped to his feet, dumping Ann to the ground. He jerked step toward him. Jonathan edged away in consternation. "He's going to run!" Olga shouted. Jonathan never stopped until he was back in the canyon leading to the plain. His nerves were jumping like fleas. He craved the soothing relaxation of a smoke. There was, he remembered, a carton of cigarettes at the wreck. He resumed his flight, but at a more sober pace. At the spot where he and Ann had first crawled away from the centaurs, he scrambled out of the gulley, glanced in the direction of his space ship. He blinked his eyes, stared. Then he waved his arms, shouted and Two men crawled out of Jonathan's wrecked freighter, glanced in surprise at Jonathan. A third man ran from the cruiser, a Dixon Ray They glanced at each other in perplexity. "I like it here," continued Jonathan. "I'm not going back." "What?" cried the three explorers in one breath. "I'm going to stay," he repeated. "I only came back here after the cigarettes." "Odd." Doctor Boynton shook his head, turned to the others. "Though if I remember correctly, there was quite an epidemic of hermits during the medieval period. It was an esthetic movement. They fled to the wilderness to escape the temptation of ." Jonathan laughed outright. "You are sure you won't return, young man?" He shook his head. They argued, they cajoled, but Jonathan was adamant. Inside the ship, Doctor Boynton moved over to a round transparent port hole. "What a strange fellow," he murmured. He was just in time to see the castaway, loaded like a pack mule, disappear in the direction from which he had come. Robinson Crusoe was going back to his man (?) Friday—all twenty-seven
