"It was," said Joyce grimly. "Look at the pool. That'll tell you where it went." The black, secretive surface was bubbling and waving as though, down in its depths, a terrific fight were taking place. "Something came up and dragged our ten-legged lizard down to its den. Then that something's brothers got onto the fact that a feast was being held, and rushed in. That pool would be no place for a before-breakfast dip!" * * * * * Wichter started to say something in reply, then gazed, hypnotized, at the opposite wall of the jungle. From the dense screen of lavender foliage stretched a glistening, scale-armored neck, as thick as a man's body at its thinnest point, which was just behind a tremendous-jawed crocodilian head. It tapered back for a distance of at least thirty feet, to merge into a body as big as that of a terrestial whale, that was supported by four squat, ponderous legs. Moving with surprising rapidity, the enormous thing slid into the mud and began ploughing a way, belly deep, toward the pool. Shapeless, slow-writhing forms were cast up in its wake, to quiver for a moment in the sunlight and then melt below the mud again. One of the bloated, formless mud-crawlers was snapped up in the huge jaws with an abrupt plunge of the long neck, and the monster began to feed, hog-like, slobbering over the loathsome carcass. Wichter shook his head, half in fanatical eagerness, half in despair. "I'd like to stay and see more," he said with a sigh, "but if that's the kind of creatures we're apt to encounter in the Zeudian jungle, we'd better be going at once--" "Sh-h!" snapped Joyce. Then, in a barely audible whisper: "I think the thing heard your voice!" The monster had abruptly ceased its feeding. Its head, thrust high in the air, was waving inquisitively from side to side. Suddenly it expelled the air from its vast lungs in a roaring cough--and started directly for their tree. "Shoot!" cried Wichter, raising his gun. * * * * * Moving with the speed of an express train, the monster had almost got to their overhanging branch before they could pull the triggers. Both shells imbedded themselves in the enormous chest, just as the long neck reached up for them. And at once things began to happen with cataclysmic rapidity. Almost with their impact the shells exploded. The monster stopped, with a great hole torn in its body. Then, dying on its feet, it thrust its great head up and its huge jaws crunched over the branch to which its two puny destroyers were clinging. With all its dozens of tons of weight, it jerked in a gargantuan death agony. The tree, enormous as it was, shook with it, and the branch itself was tossed as though in a hurricane.
