Burl told his tribesmen. They listened, eyes large with fright but not quite afraid. The thing had not yet happened. When Burl insistently commanded that they follow him on a new journey, they nodded uneasily but slipped away. He could not gather the tribe together. Always there were members who hid from him—and when he went in search of them, the ones he had gathered vanished before he could return.

There were days of bright light and murder, and nights of slow rain and death in the valley. The great creatures under the cloud-bank committed atrocities upon each other and blandly dined upon their victims. Unthinkingly solicitous parents paralyzed creatures to be left living and helpless for their young to feed on. There were enormities of cruelty done in the matter-of-fact fashion of the insect world. To these things the humans were indifferent. They were uneasy, but like other humans everywhere they would not believe the worst until the worst arrived.

Two weeks after their coming to the valley, the worst was there. When that day came the first gray light of dawn found the humans in a shivering, terrified group in a completely suicidal position. They were out in the open—not hidden but in plain view. They dared not hide any more. The furry gray monster's brood had hatched. The valley seemed to swarm with small gray demons which killed and killed, even when they could not devour. When they encountered each other they fought in slavering fury and the victors in such duels dined upon their brethren. But always they hunted for more things to kill. They were literally maniacs—and they were too small and too quick to fight with spears or clubs.

So now, at daybreak, the humans looked about despairingly for death to come to them. They had spent the night in the open lest they be trapped in the very thickets that had formerly been their protection. They were in clear sight of the large gray murderer, if it should pass that way. And they did not dare hide because of that ogreish creature's brood.

The monster appeared. A young girl saw it and cried out chokingly. It had not seen them. They watched it leap upon and murder a vividly-colored caterpillar near the limit of vision in the morning-mist. It was in the tribe's part of the valley. Its young swarmed everywhere. The valley could have been a paradise, but it was doomed to become a charnel-house.

And then Burl shook himself. He had been angry when he left his tribe. He had been more angry when he returned and they would not obey him. He had remained with them, petulantly silent, displaying the offended dignity he felt and elaborately refusing to acknowledge any overtures, even from Saya. Burl had acted rather childishly. But his tribesmen were like children. It was the best way for him to act.

They shivered, too hopeless even to run away while the shaggy monster feasted a half-mile away. There were six men and seven women besides himself, and the rest were children, from gangling adolescents to one babe in arms. They whimpered a little. Then Saya looked imploringly at Burl—coquetry forgotten now. The other whimpered more loudly. They had reached that stage of despair, now, when they could draw the monster to them by blubbering in terror.

This was the psychological moment. Burl said dourly:

"Come!"

He took Saya's hand and started away. There was but one direction in which any human being could think to move in this valley, at this moment. It was the direction away from the grisly mother of horrors. It happened to be the way up the valley wall. Burl started up that slope. Saya went with him.
