A small ball, fashioned maybe of clay, was all he saw. But why were the small thorn points sticking out of its surface all the way around? If it was meant to wound, why shoot it while the Beast Things were all well away from the spot? Fors still puzzled over that as the victors came back swinging limp bodies and proud of their killing.

In spite of his revulsion Fors could not subdue the hunger pangs when the smell of the roasting meat was heavy on the air. He could only faintly remember his last meal—his stomach was one vast empty hollow. But neither did he want to attract the attention of those who were now wolfing down the half-cooked flesh.

One of the Beast Things, while reaching for another broiled lizard, gave a sudden exclamation and plucked something from its arm, hurling it away with the force of annoyance. It had been pricked by one of the lizard - balls. But Fors could not see how that caused the victim any more than momentary discomfort. He watched closely and witnessed two of the creatures treading upon the thorn-studded globes. One of them did so when it went for a fresh supply of the water plants. And when it returned it walked slowly, stopping now and again to shake its narrow head and once to brush vigorously before its eyes as if to clear some obstruction hanging there.

They drank from the dying plants, sucked the last slender lizard bone clean, and got to their feet. Then they turned their attention to the captives. This was it. Fors grimaced. He had seen them impale and roast a screaming brokenlegged lizard—

The Beast Things circled around the captives. There was a period of rough humor during which Fors was both kicked and slapped. But they were apparently not going to kill him now. Instead the leader stooped to slit the bonds about his ankles, the mountaineer’s own knife in its paw.

That steel never bit into the hide. One of the brutes in the circle gave voice to a deep roar and bit at its own arm. Flecks of white foam showed in the corners of its jaws. It tore savagely at its. own flesh and then started on an unsteady run down the valley. With grunts of astonishment the others remained where they were, watching their companion double up with a scream of anguish and fall into the fire.

Poison! Fors knew now the cleverness of the lizards, the reason for the sacrifice of the gleaners. The thorn balls were poisoned! And there had to be time for the poison to work But—were they all infected?

In the end it was the leader who lived long enough to almost reach the other end of the valley, its paws scrabbling on the rock as it tried to drag its tortured body out of that place of death. But it crashed back, moaned twice, and then was as still as the rest.

Fors could hear the patter of lizard feet before he noticed that the hillsides were alive with them, moving in a red-brown cloud down toward the slain. He licked raw lips. Could he communicate with them, get them to use that knife lying there to saw through his bonds? His hands were numb and dead and so were his feet.

For a long time he hesitated as the lizards crowded about the dead, their thin whistling echoing up and down among the rocks. Then he ventured to make a croaking sound which was all his dry throat and dryer mouth could shape.
