Ma Kirk shrilled at her son, and two of the younger ones fought over a bone with no meat on it, rolling and snapping on the highest of all. he said. "I would like to kill them all." "Yah!" cried a shrill voice over his shoulder. "All but the Captain's yellow daughter!" Kirk spun angrily around. Lil, next below himself, danced back out of her , I bet!"

Haven't we enough trouble without that?" glowed in the feeble light. She said, "You men! He's no man, Ma. He's just a little boy who has to The young ones giggled, well out of reach. Lil's thin body was strung tight, quivering to move. "Besides," she demanded, "what have the Officers and the Engineers ever done to you that you should want to kill them—all but the Captain's yellow daughter?" Kirk's big heavy chest swelled. "Ma," he said, "you make that brat shut up or I'll whale her, anyhow." His anger forced out the forbidden words. "Where everybody says, stupid! Into the Ship." There was suddenly a lot of silence in the room. The word "Ship" hung there, awesome and accusing. Ma Kirk's eyes flicked to the curtain over Lil tossed her head. "Well neither do they." "Not when we can see 'em, no. Of course not. But how do we know they plain? Jakk says a lot goes on that we don't know about." "There must be something in the Ship that they don't want us to have. Something valuable, something they want to keep for themselves. What else could it be but heat-stones and maybe dried meat?" let the Piruts in on us, or the shags, and let 'em finish us quick. Freezing and starving would take too long. There'd be too many of us if we found out, or got mad." Kirk snorted. "You women know so much. If they let the shags or the Piruts in on us, how could they stop 'em before they killed everybody, including the Officers? As for slow death—well, they think we're dumb. They've kept us away from the Ship ever since the , and nobody talked that much before. It was the baby, crying in the cold, that set mutineer. That meant the sucking-plant.... "Listen!" said Ma Kirk. the wind, and the drifts of crystalline pebbles, and it splintered into a tangle of echoes that came from everywhere at once, but there was no mistaking it. No need even to use sensitive earcups to locate its source. the heat-stones picked dots of luminous blackness out of the gloom, wind, stamping and shivering, their head-hair and scant fur clouts blown straight out. have broken his brittle light-furred body in two. All Randl's strength only a whisper, but it had a hard edge. The baby's thin, terrible wail "Is it true, Jakk? Do you know? Because if they are...." groups of men began to run, off toward the west. The whisper of sound had grown louder in Kirk's ears. He could hear men yelling and the ringing of metal on stone. "What did you see?" piling up their dead on the swept grey stone. They were using shags again. They drove the lumbering beasts on into the hail of stones and thrown spears from the pillbox, keeping low behind them, and then climbing on the round hairy bodies. It took on the plain, and Ma and Lil and the little ones, and the baby. You had to fight the Piruts, no matter what you thought about the Officers. You the pillbox. A big raid. More Piruts than he'd ever seen before. He wondered why. It was pretty hot up there. The wall of bodies had built up so high, mostly with shags, that the Piruts were coming right over the wall. Kirk's nose wrinkled at the smell of blood. He avoided the biggest They were heavy for their size, very heavy, with sharp edges. Randl said, "Something funny, Wes. Too many Piruts. They couldn't risk 'em on an ordinary raid." "Think they could know what's in it?" Randl's narrow shoulders twitched. "Near as we know, their legend is the same as ours. Something holy in the Ship, sacred and tabu. Only the wall. drop, looking at it. There was blood on it, running clear to the elbow. "Don't move me, you fool! Just listen." His voice was harsh and rapid. beard hardly full on its sharp jaw. "Too bad." The man shook his head, and then shrugged. "Maybe it's his horny overlids. He said quietly: "I'm sorry to have to tell you this...." He hadn't, after the first glance. them as if they were strange things and no part of him. anything as hard. The Piruts didn't kill them. They were responsible, that had never happened before, like the stab of pain with no spear "I don't understand." The Officer tightened suddenly and made one hand into a fist and beat "I didn't want to give the order. God knows I didn't want to! But there was nothing else to do." Something in the Officer's voice. it. "I let them get as close as I dared," said the Officer tonelessly. "I too long as it was, hoping. The Piruts nearly broke through. Try to understand! I had to do it." "Please try to understand," whispered the Officer. "I had to do it." The Officer, the bloody wall, the stars and the cold grey gullies all enough to touch it, and no way through.

"That's mutiny. For God's sake, don't make things worse!" "Worse for us, or for you?" Kirk was shouting, holding his head up in "Shut up," he said urgently. "Don't make me punish you, not now. You're "Rot, is it? Jakk Randl knew. He saw with his own eyes and he told me down. The Officer stepped back, looking as though he had a pain in him that he didn't want to show. He said quietly, but so that everyone could hear him, "Discipline, for not longer than it takes to clear the rock below." One of the four who were left looked over the wall and spat.
