Later that night he returned to the space-ship. As he approached the gleaming ovoid a circular door opened. Crossing its threshold, he passed into the interior, distorted by intricate mechanisms, and the aperture closed behind him.
Slowly Tau walked to the center of the room, his body reflected in gleaming surfaces of berylite stanchions and sheathings. In the center of the whorled contrivances a row of ingenious troughs lay exposed. Each of these troughs was centered by a molding that had the perfect outline of a man, empty in the crystalline interior.
All that night iridescent gleamings crawled along the monstrous glassite tubes, illuminating the busy robot with an eerie splendor. Miniature lightning shot and sparkled from insulated spheres high in the nose of the craft. Pulsating, sluggish liquids gave off radiant colors and seeped through tortuous channels along the tubes of glassite. The central troughs became opaque, and formed a webwork now into which the throbbing aqueous masses were assembling. A chill current of the outer atmosphere was forced by rotating blades along a channel that whirled in a maelstrom around the central apparatus.
Tau worked swiftly, but days fled by as he watched the quiescent gauges and indicators, lengthened into months. Blinding storms raged unheeded on the exterior of the ovoid craft. Winter came and fled.
At last David and his tribe came to life, all molded from a magnificent scale. During those long months of creation, Tau had imprinted knowledge and learning upon the brains of the dormant bodies. Each awoke with a full knowledge of what had transpired on the dying planet of earth, and each knew that a strange new-born world awaited them. The largest and most magnificent man was named David. The Master had been careful in instructing Tau about that. Kendall Smith had never had a son. And this synthetic offspring in a distant life-line of the cosmos would be almost like a son for him.
All of Tau's knowledges were conveyed to David and his followers, and he led them into the unknown dangers of the pristine jungled planet, guarding them from the ferocious animals while they learned the edible fruits from the poisonous ones. Gradually David's men came to recognize the dangers and constructed weapons for their own defense.
Another winter descended upon the new world. Food had been stored in the big compartment of the space vessel. Furs of slain animals had been cured to provide clothing and warmth.
Spring thaws came and Tau led them again into the jungle, but now David was big and strong and wary, quite able to defend himself against the dangers of the forest, and Tau's presence was hardly needed, though he always hovered near.
Five men and five women had been given life by Tau's instruments, and it was inevitable that a gradual pairing off would take place. Myri, a model of womanly perfection, had grown to adore the handsome leader of the tribe, and Tau was one of the first to notice signs of fecundity.
