The Birds and the Bees BY DAVE E. FISHER Which goes to prove that, in some magnificent Melopolis, encradling the Oracle of Delni. I do not, of course, believe in the gods per se 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 returned, and settled down to live. Saddened, but resigned and content 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 seldom seen today. Indeed, Melia was on this account made the butt of been for the friendship of Xeon. Melia interrupted him quietly. "Xeon, will you lose all respect for "There is nothing left," Melia insisted. "Can more be made? And if not, 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. consternation. And can the simple people be blamed? They were aware that they stood in the midst of an unprecedented happening indeed, an Besides, had he been sober, he would not have known what to do. For who knows the mysterious workings of the machines? for me to bring them to order. Xeon and Melia stopped as I mounted the sacrifice, and finally, as the light of the sun was falling between the 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 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. "But now," he continued, however, with less assurance and indeed with machines may produce more children for us? "As I have said," he replied, "give the machines but a bit of Prelife and they will produce more. But take away that least bit, and they are helpless." 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 not doubt your word, Rocsates, for all know you are the wisest of men—if it were so, then, what of it?" we would yet have these animals among us." "And how, then, did these animals reproduce?" I asked. 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 and Melia, had not heard, but as I turned they were listening most attentively to Rocsates, who, amid cries of "Heresy" and "Treason", 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 disprove my words." "You wish to search the films—" I began. "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 only place where it may be found?" "Some of those among you are She's," he began. "And you know you are different from the rest of us. To the advantage, your skin is fairer should all be identical. Perforce you have the advantage, perforce we discovered: "That there was indeed a time before the machines, in fact the books they are not another somehow intimately related to the physical distinctions of the She's!" amazed at his words were they. And I confess, myself also. "In fact," Rocsates added, sitting down, "this process of reproduction no harm done. "For if people reproduced too often, why then this reproduction must have been a pleasant thing to do otherwise they would not have done so to excess. And if it was a pleasant thing to do, where is the necessity for the machines, and why were they created?" Rocsates seemed perplexed by this problem, whereupon Xeon, who together the process of reproduction was of such a pleasure that the Conclave At this impudence the Conclave dissolved in an uproar, and I was beyond power to restrain them from placing Xeon under arrest. Privately, Now indeed I was sorely worried concerning Xeon, for he must languish they cannot do until they meet again. formalities were over. I intended to speak for Xeon, but Rocsates was but it seems to mean...." His words trailed off. He was obviously unsure of how to continue. "I had better start at the beginning, I It is the mark of honor that a leader shall carry on when others fear to move. I cleared my throat. "Shall not these organs which you mention have atrophied by now? With no use throughout all these generations, will they not have evolved breasts. Melia has volunteered, on condition that Xeon be released from There were none, of course. Who would refuse a boon to one who would "In all honor, could Xeon allow Melia to surpass him in courage?

"My lords," he said, "would not better results be obtained were we to conduct the experiment in the fields before the Oracle of Delni, that His glance reached into my soul, and I was proud of Xeon. A true I voiced my assent, and the entire Conclave adjourned to the fields. "They seemed finally to accomplish all the book described," I muttered. "They may indeed have succeeded," Rocsates replied. "There is mentioned "It doesn't matter," I said disconsolately. "Who could ask them to go through such an ordeal again?" Melia cast her eyes down, and would not raise them. Xeon held his arm "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 "We do not deserve praise, Sias," he said. "The truth is, we ... we 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.
