Which goes to prove that, in some instances, being heroic is easy! 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 states, quite prevalent among members of the race long ago, and are seldom seen today. Indeed, Melia was on this account made the butt of many jokes and, I fear, would have had a lonely life of it had it not been for the friendship of Xeon. "Sias," they were saying, "the Maternite's gone." Melia interrupted him quietly. "Xeon, will you lose all respect for "All of it?" I asked. "There is nothing left," Melia insisted. "Can more be made? And if not, what will happen with no more children?" emergency, it is wise to speak with caution. That is, I suppose so. I have never before been in a real emergency. nenglishmin go out in the midday sun, as the ancients say, although I 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 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 Besides, had he been sober, he would not have known what to do. For who knows the mysterious workings of the machines? 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. thus assuring us, as has always been, a continuous source of Prelife to be 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. 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 helpless." Such heresy could have brought a sad end to the priest had not the 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 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 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 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— the answer beforehand. And so I acquiesced, and agreed, and granted permission. And with much misgiving and foreboding of evil, the "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 exist no reason for this? Was there not, perhaps in ancient times, a cause for this? Do you not wonder, She's, whence you come and for what reason?" 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 over-population." Order was lost among the Conclave as each man turned to speak to his neighbor, and for some time I could not restore order. I realized that something had to be done to save Rocsates before the outrage of the assembled overwhelmed him. 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, with Melia were at the Conclave without permission, shouted, "Perhaps power to restrain them from placing Xeon under arrest. Privately, however, I had to admit that his supposition was a possibility, and they cannot do until they meet again. I needed a sufficient excuse to call a meeting of the Conclave, an eon, to evolution is but an instant. And then the swelling of the some, at least, of the She's." We sat shaking our heads, bowed under terrible reality. "Then we must experiment," I said. "But whom could we ask to submit to such horror?" "I have already taken the liberty of asking for volunteers," Rocsates replied. "The She, of course, must be one with the swelling of the breasts. Melia has volunteered, on condition that Xeon be released from dungeon. Are there any objections?" There were none, of course. Who would refuse a boon to one who would undergo such an ordeal for the City? "And who will be the partner?" I asked. "In all honor, could Xeon allow Melia to surpass him in courage? It and stood, noble and naked. Rocsates gestured to the table, and Melia started to climb upon it, the gods may help us?" His glance reached into my soul, and I was proud of Xeon. A true friend, he thought even now of the comfort of Melia. The marble table 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— "They may indeed have succeeded," Rocsates replied. "There is mentioned a time lapse which is necessary. The child does not appear immediately." "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 about her shoulders, as if to protect her, but I know not from whom. "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 like to be left alone, in private, to try." "Of course," I replied. Anything they might want they could have. My relief and gratitude must have showed, for Xeon took a deep breath and spoke again. 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.
