Closer to his work he bent, watching lovingly, fearful least all might not be quite right. Then his eyes took on a brighter light as he began to see the reaction. He knew the messages that he had sent out were being received and coordinated into a unit that would stir and grow into intellect. Suddenly the machine flashed its little warning red light and automatically snapped off. Kiron twisted quickly in his seat and threw home the final switch. This, he knew, was the ultimate test. On the results of the flood of energy impulses that he had set in motion rested the fulfillment of his success--_or failure_. He watched with slight misgivings. This had never been accomplished before. How could it possibly be a success now? Even The Masters had never quite succeeded at this final test, how could he, only a servant? Yet it must work for he had no desire in life but to make it work. Then, suddenly, he was on his feet, eyes wide. From the two long, coffin-like liquid baths, there arose two perfect specimens of the _Homo sapiens_. Man and woman, they were, and they blinked their eyes in the light of the noonday sun, raised themselves dripping from the baths of their creation and stepped to the floor before Kiron. The man spoke, the woman remained silent. "I am Adam Two," he said. "Created, by you Kiron from a formula they left, in their image. I was created to be a Master and she whom you also have created is to be my wife. We shall mate and the race of Man shall be reborn through us and others whom I shall help you create." The Man halted at the last declaration he intoned and walked smilingly toward the woman who stepped into his open arms returning his smile. Kiron smiled too within his pumping heart. The words the Man had intoned had been placed in his still pregnable mind by the tele-teach phones and record that the last Master had prepared before death had halted his experiments. The actions of the Man toward the Woman, Kiron knew, was caused by the natural constituents that went to form his chemical body and govern his humanness. He, Kiron, had created a living man and woman. The Masters lived again because of him. They would sing and play and again people the magnificent crysolite city because he loved them and had kept on until success had been his. But then why not such a turnabout? Hadn't they, The Masters, created him a superb, thinking _robot_? Transcriber's Note: This etext was produced from _Comet_ July 1941.
