The river made another bend. The trail lay across the bend, clear of the trees. It was a wide bend, perhaps two miles across the neck. Ahead, where the trail joined the river again, there was a rocky hill. Something about the outlines of the hill seemed wrong to Kieran, but it was too far away to be sure of anything. Overhead the cluster burned gloriously. The people set out across the sand. Webber looked back. "You see?" he said. "Nothing." They went on. Kieran was beginning to feel very tired now, all the artificial strength that had been pumped into him before his awakening was running out. Webber and Paula walked with their heads down, striding determinedly but without joy. "What do you think now?" she asked Kieran. "Is this any way for humans to live?" The ragged line of women and children moved ahead of them, with the men in the lead. It was not natural, Kieran thought, for children to be able to travel so far, and then he remembered that the young of non-predacious species have to be strong and fleet at an early age. Suddenly one of the women made a harsh, shrill cry. Kieran looked where she was looking, off to the left, to the river and the curving line of trees. A large black shadow slipped across the sand. He looked behind him. There were other shadows, coming with long easy bounds out of the trees, fanning out in a shallow crescent. They reminded Kieran of some animal he had once seen in a zoo, a partly catlike, partly doglike beast, a cheetah he thought it had been called, only the cheetah was spotted like a leopard and these creatures were black, with stiff, upstanding ears. They bayed, and the coursing began. "Nothing," said Kieran bitterly. "I count seven." Webber said, "My God, I--" * * * * * The people ran. They tried to break back to the river and the trees that could be climbed to safety, but the hunters turned them. Then they fled blindly forward, toward the hill. They ran with all their strength, making no sound. Kieran and Webber ran with them, with Paula between them. Webber seemed absolutely appalled. "Where's that gun you had?" Kieran panted. "It's not a gun, only a short-range shocker," he said. "It wouldn't stop these things. Look at them!" They bounded, sporting around them, howling with a sound like laughter. They were as large as leopards and their eyes glowed in the cluster-light. They seemed to be enjoying themselves, as though hunting was the most delightful game in the world. One of them ran up to within two feet of Kieran and snapped at him with its great jaws, dodging agilely when he raised his arm. They drove the people, faster and faster. At first the men had formed around the women and children. But the formation began to disintegrate as the weaker ones dropped behind, and no attempt was made to keep it. Panic was stronger than instinct now. Kieran looked ahead. "If we can make it to that hill--" [Illustration]
