THE HAIRY ONES Marooned on a world within a world, aided by a slim girl and an old warrior, Patrolman Sisko Rolf was fighting his greatest must have died in the wreckage. He was alone in the waterless trap of a deep crevice. In the fading glow of the super-heated metal the vertical walls above he could see the narrow dark slit through which his feet had betrayed him, and he realized that he had fallen through The weird globe was divided equally into hemispheres, and as the tiny the other half. Toward this barrier the spinner bore him, and Rolf was had slowed its speed sunken oases and watered canyons. He drifted slowly toward the opposite loom of the mysterious wall with a swift wind off the desert behind him. "Down, Altha," a deeper voice rumbled from above, "it's one of the among the outlaws. This mysterious world that floated above the cavern floor might be their headquarters. "But, Mark," the voice that was now unmistakably feminine argued, "he with the long burnished copper of her hair down around her waist, but flesh was covered with a fine reddish coat of hair. Even her face was "Altha," he scolded, scrubbing at his reddened bald skull with a grueling years of training on Earth Base. His instructors there had known that a few gifted mortals possess the power of a limited telepathy, and the secrets of the Planet Patrol must be guarded. "That is better, perhaps." The girl's face was demure. "And now perhaps you will visit us in the safety of the vaults of ancient Aryk." their side. "I'm always forgetting the mind-reading abilities of the Hairy People." "She one of them?" Rolf's voice was low, but he saw Altha's lip twitch. "Mother was." Mark Tanner's voice was louder. "Father was Wayne Stark. Famous explorer you know. I was his assistant." "Sure." Rolf nodded. "Lost in equatorial wastelands—uh, about twenty years ago—2053, I believe." "Only we were not lost on the surface," explained Tanner, his booming he could lead the scientists of North Mars to this treasure trove of water.... "Mark!" The girl's voice was tense. Rolf felt her arm tug at his sleeve and he dropped beside her in the shelter of a clump of coarse-leaved gray bushes. "The Furry Women attack!" they filed downward from the Barrier into the blackened desolation of the desert half of Lomihi. "Enemies?" he whispered to Mark Tanner hoarsely. Barrier from the fertile plains of Nyd to raid the Hairy People. They "I must warn them." Altha's lips thinned and her brown-flecked eyes flamed. "I will take the glider." Altha was on her feet, her body crouched over to take advantage of the sheltering shrubs. She threaded her way swiftly back along a rocky corridor in the face of the Barrier toward Tanner shrugged his shoulders. "What can I do? Altha has the blood of the Hairy People in her veins. She will warn them even though the Then he knew. Above half naked feminine bodies, sinuous and supple the gray-furred muscles of their narrow bodies until they seemed utterly shoulderless, and beneath their furry pelts the ripples of "See!" Tanner's voice was muted. "Giffa, Queen of the Furry Ones!" she was, her scarred gray-furred hide hanging loose upon her breastless frame. One eye was gone but the other gleamed, black and beady, from linked together into ghastly festoons about her heavy, short-legged litter. had been cut off at the shoulders and whose naked backs bore the weals of countless lashes. Their bodies, like that of Altha, were covered "Not yet," he said. "When Altha has warned the Hairy People we can cut off their retreat. After they have passed I will arouse the Outcasts who live here upon the Barrier. Though their blood is that of the two races mingled they hate the Furry Ones." A shadow passed over their hiding place. The Furry Amazons too saw the Gone now was their chance for a surprise attack on the isolated canyons of the Hairy People. They halted, clustered about their leader. Giffa snarled quick orders the wasteland toward the nearest sunken valleys of the Hairy People. flicked its muzzle back and forth along the ranks of attacking Furry fallen sisters. Mark Tanner's bow twanged again and again as he drove arrows at the bloodthirsty warrior women. But the Furry Ones ran fearlessly into that rain of death. The Furry Amazons swarmed up over the lower terraces of rocks, their behind them, their powerful earthly muscles negating Lomihi's feeble needles at the Furry Ones and followed. Darkness thickened as they penetrated into the maze of the Barrier's desolate land of the Hairy People. Tanner's finger pointed. "Altha!" Rolf saw the graceful wings of the glider riding the thermals back toward the Barrier. "She had warned the Hairy People, and now she returns." "The weasel heads won't follow us here?" asked Rolf. "Right." Tanner kept his eyes on the enlarging winged shape of Altha's the seas and hoarding them in their underground caverns, Lomihi became "The Hairy People were the rulers," he went on, "and the Furry Ones were their slaves. In the revolt that eventually split Lomihi into two "But," Rolf frowned thoughtfully, "what keeps Lomihi from crashing into "The outlaws!" he cried. "They're after Altha." Rolf caught a glimpse of a sleek rocket flyer diving upon Altha's frail glinted with a dull bronze, were attacking them from the burnt-out wastelands. The Hairy People had come to battle the invaders. He guided the frail wing toward the shattered badlands where the girl had taken shelter, noting as he did so that the rocket flyer had landed near its center in a narrow strip of rocky gulch. A sudden thought made same movement. Expoder needles splintered the rocks about him as he dropped behind a sheltering rocky ledge, and he caught a glimpse of two green-clad men dragging the bronze-haired body of the girl he had come to save into the shelter of the flyer. A green bulge showed around the polished fuselage and Rolf pressed his controls. The bound body of Altha Stark faced him, and he saw her lips the wreck in the upper cavern and the long trek afterward through the dark tunnels had sapped his strength, and now he felt victory slipping from his grasp. He felt something soft bump against his legs, legs so far below that he could hardly realize that they were his, and then he was falling with the relentless fingers still about his throat. As from a great distant He saw Altha's bound body and head. Her jaws were clamped upon the No time to ask the girl if she were injured. The patrolman flung himself into the spongy control chair's cushions and sent the ship burned and the conditioning unit was clearing the air. "Patrolman," the girl's voice was beside him. "We're safe!" sudden strange restlessness came with the near contact. Altha smiled shyly and winced with pain. "Do you know," she said, "even yet I do not know your name." Shorty all the time," she quipped. Then they were over the Barrier and Rolf saw the last of the beaten Furry Ones racing back across the great wall toward the Plains of Nyd.
