<passage>:
still there is a grandeur in the very stones that transcends their human sculptors, and it is no wonder to me that many cling tenaciously, and ignorantly, to the old religion. Cling to the gods of old, who drew man upward from wherever he began. In whose names Man killed and plundered, while struggling up. In whose names Man finally left this earth, to seek his cousins among the stars. But of course there were no cousins. There was nothing. And Man returned, and settled down to live. Saddened, but resigned and content to live in peace with his knowledge and his power. Gone now are all the ancient evils, wars, emergencies. "Sias! Sias—" And they were upon me. That is, Xeon was upon me. But I knew that where Xeon is, Melia must soon appear. And indeed it was but a moment before Melia slipped through the high grass to stand at his side. Their youthful voices were babbling in excitement. Melia was a She, with the swelling breasts that were, so tradition many jokes and, I fear, would have had a lonely life of it had it not been for the friendship of Xeon. Melia interrupted him quietly. "Xeon, will you lose all respect for often wonder why—but Xeon and Melia ran all the way down to the city. They are of an age to enter manhood, and have all the energy such young men do. indeed, an emergency. For a machine had failed! Not in the memory of the eldest among us has a machine failed. They were created so long ago, indeed, that the ignorant believe them to have been constructed by the gods themselves. And never, so far as I know, has one failed. Small wonder that the watcher had been negligent. Indeed, the watcher is more a tradition than a necessity. for me to bring them to order. Xeon and Melia stopped as I mounted the impelled to make speeches, and one must not be disrespectful. Prayers and supplications were offered to the gods, priests were sent to sacrifice, and finally, as the light of the sun was falling between the the crux of the matter and the Conclave finally heard the facts it had assembled to hear. By this time, unfortunately, many of the Conclave had departed for home and supper. Yet perhaps it is for the best, for those left were the most earnest and intelligent. "I would not bore you," he said, "with details of which only the gods are sure. Know, then, that once granted a few cells of Prelife, it is an easy matter for the Maternite Machine to add more and more thus assuring us, as has always been, a continuous source of Prelife to be born by the Generating Machine as children. The machines bear the exact number of children each year to balance the number of us whom the gods claim. Such it has always been from time immemorial." A murmur of assent and approval of these virtuous words whispered around the Hall. actually failed." Cries of "Treason" sprang up, and I fear it might have gone hard for has been dried up. It will not function. There is no more. And there will be no more children!" At this I feared the Conclave was about to riot. It is at such times irritating dumber-than-thou attitude of his. "Must there not, long ago, have been a source of Prelife: a source now forgotten? And may it not even now—should we discover it—be available to us? I am reminded of the story of the animals of old—" "I fear your mind is wandering, Rocsates," I was forced to interrupt. "I know well the legend of the animals, but what does it have to do—" The heads of the Conclave were turning to me, quizzically. I hastened to explain the legend of the animals. "It is said that many thousands of years ago, time without reckoning, there existed on the earth creatures who were alive like us, and yet not like us. It is said to such creatures. And indeed, if they had Maternite Machines, why then we would yet have these animals among us." "And how, then, did these animals reproduce?" I asked. "How, indeed? And is there not a legend—admitted only a legend—that says there was a time before the machines, and before the Maternite Machine, and that at such a time both the animals and Men reproduced from within their own bodies?" At this two members of the Conclave fell immediately into a faint, and I would gladly have joined them. I hoped that the youngsters, Xeon went on: "I should like to ask the Conclave for permission to search the ancient records, in the hope of finding some such knowledge that would prove or "Not the films, Sias, but the books." Gods, this Rocsates! The books, as well he knows, are so ancient, and so delicate, that they are kept in an air-tight tomb lest, being handled, they be destroyed and all knowledge within them lost. Therefore, they have not been read in the known history of our race. And Rocsates has been anxious for an excuse— "Sias," he went on, "if there exists such knowledge as I seek, is it not indeed lost to the memory of Man? And if so, are not the books the and your features more often handsomer than ours. To the disadvantage, your excretory system is not so mechanically dextrous as ours. And, you should all be identical. Perforce you have the advantage, perforce we were created in that time, for not one of them mentions the machines. Then reproduction was carried on by individuals, without help of the then nonexistent machines. The She's are not wanderers from another land, but they have lived with us for all time they are not another race, but we are all types of one race. And the fact of reproduction is somehow intimately related to the physical distinctions of the She's!" These last sentences were shouted to be heard above the roar of the seems to have been so simple that there was once a problem of over-population." Order was lost among the Conclave as each man turned to speak to his Rocsates seemed perplexed by this problem, whereupon Xeon, who together power to restrain them from placing Xeon under arrest. Privately, they cannot do until they meet again. I needed a sufficient excuse to call a meeting of the Conclave, formalities were over. I intended to speak for Xeon, but Rocsates was "Shall not these organs which you mention have atrophied by now? With no use throughout all these generations, will they not have evolved into nothingness?" "I do not think so," Rocsates replied after a while. "What to us is an eon, to evolution is but an instant. And then the swelling of the breasts, I believe, proves that there is still reproductive activity in some, at least, of the She's." breasts. Melia has volunteered, on condition that Xeon be released from "In all honor, could Xeon allow Melia to surpass him in courage? It the gods may help us?" His glance reached into my soul, and I was proud of Xeon. A true was indeed hard, and from Rocsates' description it seemed that Melia's It was nearly dark when we walked home, Rocsates and I, arm in arm. It had been a horrible day. The inhuman indignity, the cries— We tarried before my home, leaned on the stone, stared at the first stars. Melia cast her eyes down, and would not raise them. Xeon held his arm "Sias, we come to tell.... We will...." He raised his eyes to mine and said manfully, "We shall try again." I am afraid that tears came to my eyes. Such sacrifice— "We beg one favor," Xeon went on. "We are agreed that—Well, we should relief and gratitude must have showed, for Xeon took a deep breath and sort of enjoy it." I watched them turn and wander off together under the stars. My heart has a warmth in it, and I no longer fear for the future of our race when our young people can show such nobility and sacrifice.
