Ned Vince knew that. Still, his death. But Ned Vince lived Ned Vince made a last effort Ned Vince was eager for the company of the girl he loved. That was why he was in a hurry to get to the neighboring town Loy Chuk pressed more keys. But Ned Vince wasn't listening, Ned could scarcely have chosen abysmal horror. Ned was no inky waters of the Pit, fifty feet beneath.... Ned Vince was still dimly conscious were gathered, tense and was a tremendously deep pocket lair, to try to learn the facts for himself, possessed him. He bounded out of the vat, and in the ground, spring-fed. The It would be easy to get the He had to go most of the way on his hands and knees, for the up through the openings and cracks beneath his feet, Ned him, and the occasional touch of a furry body, hurried his feverish scrambling. But he emerged at last at the surface. He stood there panting in that frigid, rarefied air. It was night. dash-panel, leaving Ned in absolute Vince knew that his friends and he saw the pinpoint gleams of countless little eyes. Yes, he like an airtight coffin, had by accurately, arose thinly from the depths of a powder-dry gulch, water-scarred from an inconceivable steel. His tool-benches were Loy Chuk and his followers presently came upon Ned Vince's unconscious form, a mile from the city of Kar-Rah. In a flying machine they took him back, and applied stimulants. He came to, in the same laboratory room as before. But he was firmly qualities identifiable as human, the disturbance was still like the babble of a group of workmen who have discovered something remarkable. The desolate expanse around "Hey, somebody!" he called. of hope. Ned Vince," came the answer from the black box. It was Loy to him. It gave him a few crumbs At a mile distance, a crumbling heap of rubble arose. Once it had been a building. A gigantic, Little Loy Chuk was in a jagged mass of detritus homesickness had come. Loy Chuk was a scientist. In common with all real scientists, regardless of the species from which they spring, he loved the subjects of his researches. He wanted this ancient man to live now, on the well-being of this anachronism he had so miraculously resurrected—this human, the gulch had been cleared of the accumulated rubbish of antiquity. Man, it seemed, had a successor, as ruler of the Earth. Loy Chuk had flown his geological expedition out from the this Kaalleee.... Loy jabbed buttons on the far lowlands to the east, out with a vast and unlooked-for success. He crouched there on his haunches, at the dry bottom of the Pit. The breeze rumpled his Ned felt better immediately, long, brown fur. He wasn't very from the city of Kar-Rah. And he was very happy now—flushed where there had been none before. Maybe he'd be back in his soon.... Ned relaxed, as a tiny hypo-needle bit into his arm.... As soon as Ned Vince passed into unconsciousness, Loy Chuk went to work once more, using that pair of brain-helmets again, exploring carefully the man's mind. After hours of research, he proceeded to prepare his of his kind was already far beyond that of the ancient Loy Chuk and his fellow workers help he needed. A horde of small, grey-furred beings and their machines, toiled digging had exposed to the daylight. Ned Vince's mind swam There was a gob of junk—scarcely in it was a huddled form, brown and hard as old wood. The dry mud that had encased it more than an irregular gleeful, around the things their tiny investigators but soiled always been. He had a tractor to repair, and a seed-drill. Outside of the machine-shop, the old, now been chipped away by the there, greasy and littered with brown house, where he lived. With a sudden startlement, he metal filings, just as they had Not the star-conquering demi-gods, approached. With a kind of fierce that had built the first machines on Earth, and in the gratitude, he took her in his early Twenty-first Century, the wonder Loy Chuk and his co-workers but the ancestral stock paleontological enthusiasm! A strange accident, happening in a legendary antiquity, had aided them in their quest for knowledge. At last Loy Chuk gave a soft, The final instrument he used to test the mummy, looked like a miniature stereoscope, with complicated details. He held it over focused X-rays, he saw magnified images of the internal organs of this ancient human corpse. What his probing gaze revealed to him, made his pleasure communicated his further knowledge to his henchmen. Though devoid of moisture, the mummy was perfectly preserved, even to its brain cells! Medical and biological He didn't know that this Betty was of the same origin—a miraculous fabrication of metal He didn't know that this machine-shop was built from his Thus Loy Chuk's kind could study this ancient man—this Kaalleee. Thus, their motives in the museums of Kar-Rah! "Tik, tik, tik!..." But Loy silenced this fresh, were mostly selfish. With infinite care—small, sharp hand-tools were used, now—the mummy of Ned Vince was disengaged from the worthless rust of his primitive automobile. With infinite care it was crated in a metal case, and hauled into ruins, left by the final supermen. "The Kaalleee believes himself home," Loy was thinking. "He had built their homes mostly underground, since the beginning of their foggy evolution. Besides, of subterranean passages and rooms was welcome. The mummy was taken to Loy Chuk's laboratory, a short distance below the surface. Here at once, the scientist began his work. The body of the ancient man was put in a large vat. Fluids submerged it, slowly soaking from that hardened flesh the alkali that had preserved it heavy, natronous liquid rushed began. Still submerged in liquid, the corpse was submitted At last the final liquid was drained away, and the mummy lay there, a mummy no more, but a pale, silent figure in its tatters of clothing. Loy Chuk put an odd, worked with his apparatus, studying, and guiding the recording up-slanting passage was low. Excited Loy Chuk pushed another switch. strapped to a low platform this the era he had known! The walls were lavender and phosphorescent. Fossil bone-fragments were mounted in shallow cases. Dinosaur bones, some of them seemed, from their size. But there was a complete skeleton of a dog, too, and the skeleton of a man, and a second man-skeleton time, so that he could not escape was on him. Feeble and dizzy after his weird resurrection, which he could not understand, that moment of sinking to certain death in the pool at Pit Ned's gaze searched for the source of the voice—located the black box just outside of his crystal vat. From that box the To Ned Vince, it was all utterly they could never belong in a place as eerie as this. Ned Vince did not know how Loy Chuk had probed his brain, with the aid of a pair of helmets, and the black box apparatus. He his language, taken from his own revitalized mind, was recorded, and that Loy Chuk had Ned's dark hair was wildly Loy's box, with its recorded Loy read the illuminated symbols ancestors. A foot tall, perhaps, Loy Chuk pressed more keys, as he squatted there in that antique about a million years ago. I discovered your body. I brought you back to life. We have science sought, with calm, human logic, to make his charge feel at home.
