Winslow nodded. He was plainly bewildered, lost in the new jungle. He followed Jerry, who bounded across a crevice in the earth. The ground was rotten with the honeycomb of caves and cracks. Jerry forced his way through and over a rock heap, where the thick trunks of nightmare trees were spaced farther apart. There was an opening ahead; he started forward, then stopped abruptly and motioned the other to silence. * * * * * From beyond there came sounds. There was rending of soft, pliant tissue. The sound came through the thin air from a grove up ahead, where big plants were waving, though the wind had long since ceased. To their ears came a snoring, blubbering snuffle. A stone was dislodged, to come bounding toward them from the hillside; the soft plants were flattened before it. The men cowered in the shelter of a giant fungus. Beyond the rocks, above the mottled reds and yellows of the grotesque trees, a head appeared. It waved at the end of a long, leathery neck. All mouth, it seemed to the watchers, as they saw a pair of short forelegs pull the succulent tops of the giant growth into a capacious maw. Below, there was visible a part of a gigantic, grayish body. It was crashing down toward them, eating greedily as it came. "Back," said Jerry softly. "Go back to that cave. We will hide there in some crack in the ground." They picked their way noiselessly over the rocks. The cave they had crossed offered a refuge from the beast. It went slantingly down into the ground, a great tunnel, deep in the rock. They dropped into the opening and started forward, only to recoil at the fetid stench that assailed their nostrils. "A bear pit," gasped Jerry. "Great Heavens! What a smell!" They stopped, dismayed. Far below them in the bowels of some subterranean passage was the crashing of loose stone; a scrambling and scratching of great claws came echoing to them. They leaped madly for the outer air. "Over here," Jerry directed, and led the way, crouching, to the concealment of great stalks and vine-covered rocks. He pointed toward the open ground where they had been a few moments before. The tree-eater was out in full view. Its flabby, barrel-like body was squatted like that of some unearthly, giant toad, on massive hind legs. It sat erect, its forelegs hung in air, as a hoarse, snarling cry came from the cave. The great head, perched on the long leathery neck, waved from side to side. * * * * * The noise from the cave ceased. The rift in the earth was in plain sight from where they cowered, and the eyes of the men were upon it. One instant it was empty; the next, in uncanny silence, it was filled with huge hideousness--an enormous, crouching beast.
