from! Do you understand—whoever, or whatever you are?" Loy Chuk pressed more keys. "But you can't go back to the Twentieth Century," said the only swift young reflexes to rely and make you comfortable...." inky waters of the Pit, fifty feet beneath.... Ned Vince was still dimly conscious dead birds so often floated, was surcharged with alkali. As that heavy, natronous liquid rushed up through the openings and cracks beneath his feet, Ned him, and the occasional touch of a furry body, hurried his feverish animal chucklings around couldn't fight against the force of that incoming water. The welt, left by the blow he had received on his forehead, put a thickening mist over his brain, so that he could not think clearly. liquid was sucked into his lungs. voice uttering those weird, triumphant "Kaalleee! Tik!... Tik, tik, tik!... Kaalleee!..." The excited cry, which no human throat could quite have duplicated from the depths of a powder-dry hold of his courage. But what Sun was red and huge. The air was tenuous, dehydrated, chill. in his hell-world, lost beyond the barrier of the years.... Loy Chuk and his followers presently came upon Ned Vince's unconscious form, a mile from "Kaalleee!... Tik, tik, tik!..." At first there was only one 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 sounds. Then other vocal organs took up that trilling again. There he lay, helpless, until presently an idea occurred to him. It gave him a few crumbs from the black box. It was Loy Chuk speaking again. "But listen!" Ned protested. "You know a lot more than we could send me back to my own time after all!" Little Loy Chuk was in a black, discouraged mood, himself. He could understand the than this, death from homesickness had come. Loy Chuk was a scientist. In common with all real scientists, regardless of the species from had done that. "Kaalleee!... Tik, tik, tik!..." The sounds were not human. They were more like the chatter study. So Loy considered carefully what Ned Vince had suggested. resurrected—this human, this Kaalleee.... Loy jabbed buttons on the Man, it seemed, had a successor, as ruler of the Earth. Loy Chuk had flown his geological expedition out from the far lowlands to the east, out black box. "Yes, Ned Vince," from the city of Kar-Rah. And accomplish, but we'll try. Now I shall put you under an anesthetic...." Ned felt better immediately, he was very happy now—flushed for there was real hope now, yourself, here. It will be hard to 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, far beyond that of the ancient Twentieth Century. Loy Chuk and his fellow workers were gathered, tense and gleeful, around the things their of which Loy was a prime member. It would be easy to get the help he needed. tiny investigators not this body. The answer to this saturation that had held time and change in stasis. A perfect preservative for organic tissue, aided probably during most of those passing eras by desert dryness. mummy. first interplanetary rockets. No wonder Loy Chuk and his co-workers were happy in their paleontological enthusiasm! A legendary antiquity, had aided them in their quest for knowledge. At last Loy Chuk gave a soft, chirping signal. The chant of triumph ended, while instruments flicked in his tiny hands. test the mummy, looked like a He did not know anything within, through the agency of focused X-rays, he saw magnified images of the internal organs and dimming his brain, so that it would never question or doubt, or observe too closely the incongruous of this ancient human beating down upon him, soothing about the invisible radiations devoid of moisture, the mummy its brain cells! Medical and biological sciences were far advanced among Loy Chuk's kind. Perhaps, by the application of principles long known to them, opaque dome. But there were hidden television systems, too. Thus Loy Chuk's kind could study this ancient man—this "Tik, tik, tik!..." But Loy silenced this fresh, eager chattering with a command. Kaalleee. Thus, their motives Loy, though, was not observing, now. He had wandered far out into cold, sad sea-bottom, to mummy of Ned Vince was substantial than cheering. With infinite care—small, sharp hand-tools were used, now—the in a metal case, and hauled into the flying machine. Flashing flame, the latter glinting in the red sunshine. But this was only its surface aspect. Loy Chuk's people had built their homes mostly underground, since the beginning in this latter day, the nights were very cold, the shelter 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 for so long. The fluid was changed often, until woody muscles and other tissues became pliable once more. began. Still submerged in liquid, the corpse was submitted to a flow of restorative energy, passing between complicated electrodes. The cells of antique flesh and brain gradually took on a chemical composition nearer to that of the life that they had 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, metal-fabric helmet on its head, and a second, much smaller helmet At last, eager and ready for whatever might happen now, Loy Chuk pushed another switch. With a cold, rosy flare, energy blazed around that moveless form. dehydrated, his brain had been kept perfectly intact through the ages, and now it was restored. was on him. Feeble and dizzy after his weird resurrection, which he could not understand, in the museums of Kar-Rah! source of the voice—located the black box just outside of his crystal vat. From that box the 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 only to press certain buttons to make the instrument express his thoughts in common, long-dead English. Loy, whose vocal organs were not human, would have had a curious calm. "Stark—starin'—nuts...." Loy's box, with its recorded English words and its sonic detectors, could translate for its master, too. As the man spoke, Loy read the illuminated symbols in his own language, flashed on a frosted crystal plate before him. Thus he knew what Ned Vince was saying. Loy Chuk pressed more keys, and the box reproduced his answer: "No, Ned, not nuts. Not a your body. I brought you back to life. We have science that can do that. I'm Loy Chuk...." It took only a moment for the box to tell the full story in clear, bold, friendly terms. Thus Loy sought, with calm, human logic, to make his charge feel at home.
