It was black, a dull leathery black. Its thick, hairless hide hung in creases and folds on a gaunt frame. Shorter than the tree-eater, it was still a thing of mammoth ugliness. Its hind legs were powerful and armed with claws that curved deep into the earth; its front legs displayed the same fearful weapons. A thick, heavy tail slashed forward and back over the ground. And from this to the grinning, heavy-toothed jaws and beady eyes where the long neck ended in a warty head, it was an incarnation of pitiless ferocity.
Was the scent of the hidden, shuddering men in its red nostrils? It forgot them at the sight of the beast in the clearing. The snarling cry echoed hideously in the thin air as the frightful body came erect with neck extended, jaws open and dripping. It hurled itself through the air in one terrific leap.
Had there been any lingering hope in the minds of the men that they had no carnivores to deal with, the ensuing struggle ended it. The attacker tore great masses of living flesh from the struggling, screaming body. The first cumbersome brute was helpless before its destroyer.
erry was trembling and sick at the sight, but he grasped his companion's arm and drew him after as he slipped quietly away.
"To the high ground," he whispered. "It's our only hope. Perhaps we can fight them off there—find some steep rock we can climb." They worked their way desperately through the rubbery, obstructing growth.
At the foot of the hill there was better going; the bare rock gave winding and twisting passage to the heights. They could have leaped over the stunted growths here, could have raced frantically for the high ground, but they dared not. To leap up into view of those fierce, searching eyes! It was unthinkable. They crouched low as they darted from their concealment to new shelter, and crawled behind rocks when open ground must be crossed.
They had dared regain hope when again the paralyzing scream ripped through the silence. It was answered by another and another from distant points. The valley of the caves was spewing out its loathsome dwellers from their winter's sleep.
The men raced openly now for the heights. As he leaped, Jerry turned to see over one shoulder a pursuer appear. It was one of the flesh-eaters, head to the ground on their trail. At sight of them its cry rang out again. It bounded forward in pursuit. And again there were answering screams from the jungle growth.
