They know these caverns better than.... We'll down some of them, though." their invisible preliminary jets of gas, and three times an enemy craft flared up into an intolerable torch of flame before they realized the patrol ship had fired upon them. Then a barrage of enemy rocket shells Rolf swung the lax controls over hard as the bursts of fire revealed a The ship struck split open like a rotten squash, and Rolf felt himself being flung far outward through thick blackness. For an eternity it seemed he hung in the darkness before something smashed the breath and feeling from his nerveless body. With a last glimmer of sanity he knew that he lay crushed against a rocky wall. Much later Rolf groaned with the pain of bruised muscles and tried to he could see the narrow dark slit through which his feet had betrayed him, and he realized that he had fallen through the other half. Toward this barrier the spinner bore him, and Rolf was it seemed to Rolf that he must be falling free through black dust, and he came to a stop. Deftly Rolf nested the Rolf found himself staring, open-mouthed, at the sleek-limbed vision Rolf threw up the mental block that was the inheritance from his "Sorry," said the tall man as Rolf sprang easily from the ground to "She one of them?" Rolf's voice was low, but he saw Altha's lip twitch. paused to look nervously out across the blasted wasteland. "We ran out of fuel here on Lomihi," he finished, "with the vanished Rolf followed the direction of the other's pale blue eyes. Overhead now gray bushes. "The Furry Women attack!" A hundred paces away Rolf made the dark shapes of armed warriors as they filed downward from the Barrier into the blackened desolation of the desert half of Lomihi. "Enemies?" he whispered to Mark Tanner hoarsely. "Right." The older man was slipping the stout bowstring into its notched recess on the upper end of his long bow. "They cross the take them for slaves." "I must warn them." Altha's lips thinned and her brown-flecked eyes flamed. "The outlaws may capture," warned Tanner. "They have taken over the Rolf watched the column of barbarically clad warriors file out upon the Spear tips and bared swords glinted dully. "They will pass within a few feet!" he hissed. not shift, their nostrils are sensitive as those of the weasels they calling them weasels, wondered until they came closer. the gray-furred muscles of their narrow bodies until they seemed utterly shoulderless, and beneath their furry pelts the ripples of smooth-flowing muscles played rhythmically. There was a stench, a musky "See!" Tanner's voice was muted. "Giffa, Queen of the Furry Ones!" had been cut off at the shoulders and whose naked backs bore the weals Rolf raised his expoder, red anger clouding his eyes as he saw these 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 Rolf and Mark Tanner came to their feet. bearing the scent of their bodies out to the sensitive nostrils of the beast-women. Again the column turned. They glimpsed the two men and a hideous scrawling battle-cry burst from their throats. Rolf's expoder rattled briefly like a high-speed sewing machine as he flicked its muzzle back and forth along the ranks of attacking Furry arrows at the bloodthirsty warrior women. But the Furry Ones ran fearlessly into that rain of death. The expoder hammered in Rolf's heavy fist. Tanner smashed an elbow into Rolf's side. "Retreat!" he gasped. The Furry Amazons swarmed up over the lower terraces of rocks, their "Now where?" Rolf snapped another burst of expoder needles at the furry needles at the Furry Ones and followed. shattered heart. An unseen furry shape sprang upon Rolf's shoulders Tanner's finger pointed. "Altha!" Rolf saw the graceful wings of the glider riding the thermals back toward the Barrier. "She had warned the "The weasel heads won't follow us here?" asked Rolf. Rolf laughed. "Like the pleasure globes of the wealthy on Earth." "The Hairy People were the rulers," he went on, "and the Furry Ones "The outlaws!" he cried. "They're after Altha." Rolf caught a glimpse of a sleek rocket flyer diving upon Altha's frail The older man's eyes were hot. He jerked at Rolf's hands and then suddenly thought better of it. "You're right," he agreed. "Help her if you can. Your weapon is our only hope now." Rolf pushed up and outward with all the strength of his weary muscles. over the Barrier. The Furry Ones were struggling insect shapes below him, and he saw with a thrill that larger bodied warriors, whose bodies glinted with a dull bronze, were attacking them from the burnt-out A man stood on guard just outside the flyer's oval door. Rolf lined up comrades. But if the outlaw saw him Rolf knew that he would be the momentarily. In that instant Rolf launched himself from the open A green bulge showed around the polished fuselage and Rolf pressed his captured weapon's firing button. A roar of pain came from the wounded man, and he saw an outflung arm upon the rocky ground that clenched Rolf heard voices from a distance and the answering triumphant bawling "Fire!" There was panic in the outlaw's voice. Rolf came to his knees in the blanketing fog and looked forward. One of the men flung himself out the door, but the other reached for the extinguisher close at hand. His thoughts were on the oily smoke not on the prisoners, and so the impact of Rolf's horizontally propelled body drove the breath from his lungs before his hand could drop to his belted expoder. jolted upward toward the patrolman's vulnerable middle. But Rolf bored in, his own knotted hands pumping, and his trained body weaving instinctively aside from the crippling blows aimed at his body. For a moment they fought, coughing and choking from the thickening pall of The patrolman was weary 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.
