An intolerably bright light that seemed to sear his eyeballs was the first thing of which Jim was conscious. Then he became aware of his aching head, of a sense of utter lassitude, as if he had been bruised all over in some machine that had caught him up and held him in its grip for endless aeons. At last, despite the pain in his eyes, he managed to get his eyelids open. He tried to struggle to his feet, only to discover that he was firmly bound with what appeared to be tough creepers, pliant as ropes. After the lapse of a few minutes, during which he struggled with the receding waves of unconsciousness, he came to a realization of his surroundings. That light that had so distressed him--though the effects were now beginning to pass off--was a pillar of smoke and flame, shooting out of the crater of a volcano about a mile away, across a valley. He was lying in the entrance to a cave, pegged out on his back, and bound by the tough creepers to the stakes driven into the ground. Up to the mouth of the cave grew huge tree-ferns, cattails, cycads, and such growths as existed in earlier ages in the warm, moist regions of the world. Beneath the level of the cave a heavy white fog completely shrouded the valley, extending up to within a short distance of the volcano opposite. But on the upper slopes of the volcano the sunlight played, making its crater a sheen of glassy lava, intolerably bright. Beyond the volcano Jim could see what looked like an expanse of ocean. * * * * * He groaned, and at the sound a creature came shambling forward, carrying what looked like a huge melon in either hand. Jim recognized the Drilgo, Cain. Chattering and mumbling, Cain placed one of the fruits to Jim's mouth. It was a sort of bread-fruit, but he was too nauseated to eat, and rejected it with disgust. Cain offered him the second fruit. It was a hollow gourd, the interior filled with a clear fluid. Jim drank greedily as the Drilgo put it to his lips. The contents were like water, but slightly acid. Jim felt refreshed. He looked about him. The Drilgo uttered a chattering call, and immediately a host of the savages swarmed into the cave. Men--undoubtedly men, in spite of the brow ridges and the receding foreheads, carrying long spears, consisting of chipped and pointed heads of stone, with holes bored in them, through which long bands of creepers passed, fastening them firmly to the shaft. Chattering and gesticulating, the Drilgoes surrounded Jim as he lay helpless on the ground. Their savage faces, their rolling eyes, the threatening gestures that they made with their spears, convinced Jim that his end was a foregone conclusion.
