Hume made sense, much as Rynch disliked admitting it. And the Hunter must have read something of his agreement in his face for now he nodded and added briskly:
"Best place now is the safari camp. We'll head back at once."
Only time had run out. A noise sounded with a metallic ring. Rynch whirled, needler cocked. A glittering ball about the size of his fist rolled away from contact with a boulder, came to rest in the deep depression of one of Hume's boot tracks. Then another flash through the air, a clatter as a second ball spun across a patch of gravel.
The balls seemed to appear out of the air. Displaying rainbow glints they rolled in a semicircle about the two men. Rynch stooped, then Hume's fingers latched about his wrist, dragging his hand away from the globe. It was only then that he realized that sharp action had detached his attention from that ball he had wanted to take up.
"Don't touch!" Hume barked. "And don't look at that too closely! Come along!" He pulled Rynch forward through the yet unclosed arc of the globe circle.
Hume detoured around the feasting scavengers and brought Rynch with him at a trot. They could hear behind them the plop and tinkle of more globes. Glancing back Rynch saw one fall close to the bodies of the water-cats.
"Wait a minute!" He pulled back against Hume's hold. Here was a chance to see what effect that crystal had on the clawed carrion eater.
There was a change in the crystal: Yellow now, then red--red as the few scraps of fur remaining on the rapidly disappearing body.
The pulsating carpet which had covered the dead feline ceased to move. But towards that spot rolled two more of the globes, approaching the scavengers. Now the clawed things were stirring, dropping away from their prey. They spread out in a patch, moved purposefully forward. Behind them, as guardians might head a flock, rolled three globes, flushing scarlet, then more.
Hume's hand came up. From the cone tip of the ray tube spat a lance of fire, to strike the middle crystal. The beam was reflected into the block of scavengers. Scaled bodies, twisted, crisped, were ash. But the crystal continued to roll at the same pace.
"Move!" Hume's other hand hit Rynch's shoulder, knocked him forward in an impetuous shove which nearly took him off his feet. Both men began to run.
