It was in a wide savannah among the jungles that he first caught sight of the monsters. At first he thought it was the rising dawn mist; then he began to distinguish a certain horrible resemblance to human forms, and swooped down, banking round and round the opening in the jungle until he could see clearly. There were perhaps a score of them, an advance guard that had pushed forward from one of the main divisions. Men? Anthropoids, rather, for their sex was indistinguishable! Human forms ranging from a few feet to a hundred, composed apparently of a grayish jelly, propelling themselves clumsily on two feet, but floating rather than walking. Translucent, semi-transparent. Most horrible of all, these shadowy, spheroid creatures exhibited here and there buds of various sizes, which were taking on the similitude of fresh forms. And among them were the young, the buds that had fallen from the parent stems, fully formed humans of perhaps five or six feet, bouncing with a horrible playfulness among their sires. As Kay soared some three hundred feet overhead, a young tapir came leaping out of the jungle and ran, apparently unconscious of their presence, right toward the monsters. Suddenly it stopped, and Kay saw that it was already encircled by coils of protoplasm, resembling arms, which had shot forth from the bodies of the devils. * * * * * Swiftly, despite its struggles and bleatings, the tapir was drawn into the substance of the monsters, which seemed to fuse together and form a solid wall of protoplasm in all respects like the agglutination of bacteria under certain conditions. Then the beast vanished in the wall, whose agitated churnings alone gave proof of its existence. For perhaps ten minutes longer Kay remained hovering above the clearing. Then the bodies divided, resuming their separate shapes. And the white bones of the tapir lay in a huddled mass in the open. Kay went mad. Deliberately he set down his plane, and, hatchet in hand, advanced upon the sluggish monsters. Shouting wildly, he leaped into their midst. The fight that followed was like a nightmare fight. He lopped off the slow tentacles that sought to envelop him, he slashed the devils into long ribbons of writhing jelly, slashed until the substance blunted the ax; wiped it clean and leaped into their midst again, hewing until he could no longer raise his arm. Then he drew back and surveyed the scene before him. It was dreadful enough to drive the last remnants of sanity from his brain. For every piece that he had cut from the monsters, every protoplasmic ribbon was reorganizing before his eyes into the semblance of a new creature. Where there had been a score, there were now five hundred! Kay ran back to his plane, leaped in, and soared southward. His face was a grotesque mask of madness, and his cries rang out through the ether. * * * * *
