strange country with no bold chief to guide them. He was the first man to whom the tribe had ever offered allegiance, but their submission had been all the more complete for that fact, and his loss was the more appalling. Burl had mistaken their lack of timidity. He had thought it independence, and indifference to him. As a matter of fact, it was security because the tribe felt safe under his tutelage. Now that he had vanished, and in a fashion that seemed to mean his death, their old fears returned to them reenforced by the strangeness of their surroundings. They huddled together and whispered their fright to one another, listening the while in panic-stricken apprehension for signs of danger. The tribesmen visualized Burl caught in fiercely toothed limbs, being rent and torn in mid air by horny, insatiable jaws, his blood falling in great spurts toward the earth below. They caught a faint, reedy cry, and shuddered, pressing closer together. And so through the long night they waited in trembling silence. Had a hunting spider appeared among them they would not have lifted a hand to defend themselves, but would have fled despairingly, would probably have scattered and lost touch with one another, and spent the remainder of their lives as solitary fugitives, snatching fear-ridden rest in strange hiding-places.

But slowly, as the morning wore on, some of the moisture that had kept the skin soft and flaccid during the night evaporated. The skin had a strong tendency to contract, like green leather when drying. The spores within it strove to expand. The opposing forces produced a tension that grew greater and greater as
