Their faces, unlike the bleached-blood horrors he had seen, were aglow with the flush of health. They were tall, slenderly built, graceful in their quick motions as they worked to revive the unconscious man. One stopped, as he passed, to lay a cool hand on McGuire's forehead, and the eyes that looked down seemed filled with the blessed quality of kindness. They were human--his own kind!--and McGuire was unable to take in at first the full wonder of it. Did the tall man speak? His lips did not move, yet McGuire heard the words as in some inner ear. "We were awaiting you, friend Mack Guire." The voice was musical, thrilling, and yet the listening man could not have sworn that he heard a voice at all. It was as if a thought were placed within his mind by the one beside him. The one who had paused hurried on to aid the others, and McGuire let his gaze wander. * * * * * The porthole beside him showed dimly a pale green light; they were submerged, and the hissing rush of water told him that they were travelling fast. There was a door in the farther wall; beyond was a room of gleaming lights that reflected from myriads of shining levers and dials. A control room. A figure moved as McGuire watched, to press on a lever where a red light was steadily increasing in brightness. He consulted strange instruments before him, touched a metal button here and there, then opened a switch, and the rippling hiss of waters outside their craft softened to a gentler note. The tall one was beside him again. "Your friend will live," he told him in that wordless tongue, "and we are almost arrived. The invisible arms of our anchorage have us now and will draw us safely to rest." The kindly tone was music in McGuire's ears, and he smiled in reply. "Friends!" he thought. "We are among friends." "You are most welcome," the other assured him, "and, yes, you are truly among friends." But the lieutenant glanced upward in wonder, for he knew that he had uttered no spoken word. Their ship turned and changed its course beneath them, then came finally to rest with a slight rocking motion as if cushioned on powerful springs. Sykes was being assisted to his feet as the tall man reached for McGuire's hand and helped him to rise. The two men of Earth stood for a long minute while they stared unbelievingly into each other's eyes. Their wonder and amazement found no words for expression but must have been apparent to the one beside them. "You will understand," he told them. "Do not question this reality even to yourselves. You are safe!... Come." And he led the way through an opening doorway to a wet deck outside. Beyond this was a wharf of carved stone, and the men followed where steps were inset to allow them to ascend.
