"But could stored sunshine alone give enough warmth for the luxuriant growth of those jungles?" "An overabundance of the Life Ray is responsible for the miraculous growth of all life in New Eden. The Life Ray is Nature's most powerful force. Yet Nature is often niggardly and paradoxical in her use of her powers. In New Eden, we have forced the powers of creation to take ascendency over the powers of destruction." At Northwood's sudden start, the scientist laughed and continued: "Is it not a pity that Nature, left alone, requires twenty years to make a man who begins to die in another ten years? Such waste is not tolerated in New Eden, where supermen are younger than babes and--" "Come, worms; let's land." It was Adam's voice. Suddenly he materialized, a blond god, whose eyes and flesh were too new. * * * * * They were in a world of golden skylight, warmth and tropical vegetation. The field on which they had landed was covered with a velvety green growth of very soft, fine-bladed grass, sprinkled with tiny, star-shaped blue flowers. A balmy, sweet-scented wind, downy as the breeze of a dream, blew gently along the grass and tingled against Northwood's skin refreshingly. Almost instantly he had the sensation of perfect well being, and this feeling of physical perfection was part of the ecstasy that seemed to pervade the entire valley. Grass and breeze and golden skylight were saturated with a strange ether of joyousness. At one end of the field was a dense jungle, cut through by a road that led to the towering building from which, while above in the sun-ship, they had seen the golden light issue. From the jungle road came a man and a woman, large, handsome people, whose flesh and eyes had the sinister newness of Adam's. Even before they came close enough to speak, Northwood was aware that while they seemed of Adam's breed, they were yet unlike him. The difference was psychical rather than physical; they lacked the aura of hate and horror that surrounded Adam. The woman drew Adam's head down and kissed him affectionately on both cheeks. Adam, from his towering height, patted her shoulder impatiently and said: "Run on back to the laboratory, grandmother. We're following soon. You have some new human embryos, I believe you told me this morning." "Four fine specimens, two of them being your sister's twins." "Splendid! I was sure that creation had stopped with my generation. I must see them." He turned to the scientist and Northwood. "You needn't try to leave this spot. Of course I shall know instantly and deal with you in my own way. Wait here." He strode over the emerald grass on the heels of the woman. Northwood asked: "Why does he call that girl grandmother?" "Because she is his ancestress." He stirred uneasily. "She is of the first generation brought forth in the laboratory, and is no different from you or I, except that, at the age of five years, she is the ancestress of twenty generations."
