But no Utopia is perfect, and this one had two blemishes. The first was the marauding leopard, whose passion for man-apes seemed to have grown even stronger now that they were better nourished. The second was the tribe across the river; for somehow the Others had survived, and had stubbornly refused to die of starvation.
The leopard problem was resolved partly by chance, partly owing to a serious indeed almost fatal error on Moon-Watcher's part. Yet at the time his idea had seemed such a brilliant one that he had danced with joy, and perhaps he could hardly be blamed for overlooking the consequences.
The tribe still experienced occasional bad days, though these no longer threatened its very survival. Toward dusk, it had failed to make a kill; the home caves were already in sight as Moon-Watcher led his tired and disgruntled companions back to shelter. And there, on their very threshold, they found one of nature's rare bonanzas. A full-grown antelope was lying by the trail. Its foreleg was broken, but it still had plenty of fight in it, and the circling jackals gave its daggerlike horns a respectful berth. They could afford to wait; they knew that they had only to bide their time. But they had forgotten about the competition, and retreated with angry snarls when the man-apes arrived.
They too circled warily, keeping beyond the range of those dangerous horns; then they moved to the attack with clubs and stones.
It was not a very effective or coordinated attack; by the time the wretched beast had been given its quietus the light had almost gone and the jackals were regaining their courage. Moon-Watcher, torn between fear and hunger, slowly realized that all this effort might have been in vain. It was too dangerous to stay here any longer.
Then, not for the first or the last time, he proved himself a genius. With an immense effort of imagination, he visualized the dead antelope in the safety of his own cave. He began to drag it toward the cliff face; presently, the others understood his intentions, and began to help him.
If he had known how difficult the task would be, he would never have attempted it. Only his great strength, and the agility inherited from his arboreal ancestors allowed him to haul the carcass up the steep slope. Several times, weeping with frustration, he almost abandoned his prize, but a stubbornness as deep-seated as his hunger drove him on. Sometimes the others helped him, sometimes they hindered; more often, they merely got in the way. But finally it was done; the battered antelope was dragged over the lip of the cave, as the last hues of sunlight faded from the sky; and the feasting began.
Hours later, gorged to repletion, Moon-Watcher awoke. Not knowing why, he sat up in the darkness among the sprawled bodies of his equally satiated companions, and strained his ears into the night.
There was no sound except the heavy breathing around him; the whole world seemed asleep. The rocks beyond the mouth of the cave were pale as bone in the brilliant light from the moon, now high overhead. Any thought of danger seemed infinitely remote.
Then, from a long way off, came the sound of a falling pebble. Fearful, yet inquisitive, Moon-Watcher crawled out onto the ledge of the cave and peered down the face of the cliff.
What he saw left him so paralyzed with fright that for long seconds he was unable to move. Only twenty feet below, two gleaming golden eyes were staring straight up at him; they held him so hypnotized with fear that he was scarcely aware of the lithe, streaked body behind them, flowing smoothly and silently from rock to rock. Never before had the leopard climbed so high. It had ignored the lower caves, though it must have been well aware of their inhabitants. Now it was after other game; it was following the spoor of blood, up the moon-washed face of the cliff.
Seconds later, the night was made hideous by the shrieks of alarm from the man-apes in the cave above. The leopard gave a snarl of fury as it realized that it had lost the element of surprise. But it did not check its advance, for it knew that it had nothing to fear.
It reached the ledge, and rested for a moment on the narrow open space. The scent of blood was all around, filling its fierce and tiny mind with one overwhelming desire. Without hesitation, it padded silently into the cave.
And here it made its first error, for as it moved out of the moonlight even its superbly night-adapted eyes were at a momentary disadvantage. The man-apes could see it, partly silhouetted against the opening of the cave, more clearly than it could see them. They were terrified, but they were no longer utterly helpless.
Snarling and lashing its tail in arrogant confidence, the leopard advanced in search of the tender food that it craved. Had it met its prey in the open, it would have had no problems; but now that the man-apes were trapped, desperation had given them the courage to attempt the impossible. And for the first time they had the means to achieve it.
The leopard knew that something was wrong when it felt a stunning blow on its head. It lashed out with its forepaw, and heard a shriek of agony as its claws slashed through soft flesh. Then there was a piercing pain as something sharp drove into its flanks once, twice, and yet a third time. It whirled around to strike at the shadows screaming and dancing on all sides.
Again there was a violent blow as something caught it across the snout. Its teeth snapped on a white, moving blur only to grate uselesssly upon dead bone. And now in a final, unbelievable indignity its tail was being dragged out by the roots.
It whirled around, throwing its insanely daring tormentor against the wall of the cave. Yet whatever it did, it could not escape the rain of blows, inflicted on it by crude weapons wielded by clumsy but powerful hands. Its snarls ran the gamut from pain to alarm, from alarm to outright terror. The implacable hunter was now the victim, and was desperately trying to retreat.
And then it made its second mistake, for in its surprise and fright it had forgotten where it was. Or perhaps it had been dazed or blinded by the blows rained on its head; whatever the case, it bolted abruptly from the cave. There was a horrible screech as it went toppling out into space. Ages later, it seemed, there came a thud as it crashed into an outcropping halfway down the cliff; thereafter, the only sound was the sliding of loose stones, which quickly died away into the night.
For a long time, intoxicated by victory, Moon-Watcher stood dancing and gibbering at the entrance of the cave. He rightly sensed that his whole world had changed and that he was no longer a powerless victim of the forces around him.
Then he went back into the cave and, for the first time in his life, had an unbroken night's sleep.
In the morning, they I found the body of the leopard at the foot of the cliff. Even in death, it was some time before anyone dared to approach the vanquished monster, but presently they closed in upon it, with their bone knives and saws.
It was very hard work, and they did no hunting that day.
5 Encounter in the Dawn
As he led the tribe down to the river in the dim light of dawn, Moon-Watcher paused uncertainly at a familiar spot. Something, he knew, was missing; but what it was, he could not remember. He wasted no mental effort on the problem, for this morning he had more important matters on his mind.
Like thunder and lightning and clouds and eclipses, the great block of crystal had departed as mysteriously as it had come. Having vanished into the nonexistent past, it never troubled Moon-Watcher's thoughts again.
He would never know what it had done to him; and none of his companions wondered, as they gathered round him in the morning mist, why he had paused for a moment here on the way to the river.
