"But who . - . what-" Bill choked a little on his own amazement and fell silent, marveling at the strange warm tenderness that was flooding up in him as he watched this familiar face he had never seen before. A tenderness more melting and protective and pa.s.sionately selfless than he had ever imagined a man could feel. Dizzy with complete bewilderment, too confused to wonder if he dreamed, he tried again. "Who are you? What are you doing here? How did-"

"But I'm not there-not really." The sweet face smiled again, and Bill's heart swelled until his throat almost closed with a warmth of pride and tenderness he was too dizzy to a.n.a.lyze now. "I'm here- here at home in Eden, talking to you across the millennium! Look-"

Somehow, until then he had not seen beyond her. Sallie's face had smiled out of a mist of tulle, beyond which the cube had been crystal-clear. But behind the face which was no longer wholly Salli~'s, a green hillside filled the cube. And, very strangely, it had no look of smallness. Though the cube's dimensions confined it, here was no miniature scene he gazed upon. He looked through the cube as through a window, out into a forest glade where upon a bank of green myrtle at the foot of a white garden wall a little group of tanned men and women reclined in a circle with closed eyes, lying almost like corpses on the dark, glossy leaves. But there was no relaxation in them. Tensity more of the spirit than the body knit the group into a whole, focused somehow upon the woman in the circle's center-this fair-haired woman who leaned forward with her elbows on her knees, chin in hand, staring brown-eyed and tensely into s.p.a.ce-into Bill Cory's eyes. Dimly he realized that his perception had expanded as he stared.

Awareness now of a whole countryside beyond her, just over the garden wall, made this cube that had housed Sallie's careless smile a window indeed, opening upon distance in s.p.a.ce and time far outside his imagining.

He knew he was dreaming. He was sure of it, though the memory of what Ashley had been saying hovered uneasily in the back of his mind, too elusive now to be brought consciously into view. But in this impossible dream he clenched his hands hard in his pockets, taking a firm hold upon reality."Just who are you, and what do you want? And how did you-"

She chose to answer the last question first, breaking into it as if she could read his thoughts as she knelt staring on the myrtle leaves.

"I speak to you along an unbroken cord between us-father. Thousands of times removed, but-father.

A cord that runs back through the lives that have parted us, yet which unite us. With the help of these people around me, their full mental strength supple-menting mine, we've established contact at last, after so many fail-ures, so much groping in mysteries which even I understand only partly, though my family for generations has been trained in the secrets of heredity and telepathy."

"But why-"

"Isn't the fact of achievement an end in itself? Success in es-tablishing a two-way contact with the past, in talking to one's own ancestors-do I need more reason for attempting that than the pure joy of achieving it? You wonder why you were chosen. Is that it? Because you are the last man in a direct line of males to be born into my family before the blessed accident that saved the world from itself.

"Don't look so bewildered!" Laughter bubbled from the cube-or was it a sound in his own brain? "You aren't dreaming! Is it so incred-ible that along the unbroken cord of memories which links your mind to mine the current might run backward against the time flow?"

"But who are you? Your face-it's like-"

"My face is the face of the daughter that Sallie Cory bore you, thousands of years ago. That resemblance is a miracle and a mystery beyond all understanding-the mystery of heredity which is a stranger thing than the fact of our communication. We have wondered among ourselves if immortality itself-but no, I'll have mercy on you!"

This bewilderingly beloved face that had darkened with mystical brooding, flashed suddenly alive again with swift laughter, and hear-ing it, catching a lift of the brows that was his and a quirk of the soft lips that was Sallie's own, Bill made no effort to stem the tide of warm affection rising higher and higher in him. It was himself looking out of this cube through Sallie's brown eyes-himself exultant in achieve-ment for the simple sake of achieving. She had called him father. Was this a father's love, selfless, unfathomable, for a lovely and beloved daughter?

"Don't wonder any more," laughed the voice in his ears. "Look- here's the past that lies between us. I want you to understand what parts your world from mine."

Softly the myrtle glade and the lovely smiling face that blended Sallie and Bill melted into the depths of a cloud forming inside the three dimensions of the cube. For a moment-nothing. Then motion was lifting behind the mist, shouldering the veils aside. Three-dimen-sional s.p.a.ce seemed to open up all around him- He saw a wedding procession coming down a church aisle toward him, Sallie smiling mistily through a cloud of silver tulle. And he knew at the sight of her that though it was only chance which had chosen her instead of dark Marta Mayhew, he could come to love Sallie Carlisle Cory with an intensity almost frightening.

He saw time go by with a swiftness like thought itself, events tele-scoping together with no sense of confusion, moving like memories through his mind, clear, yet condensed into split seconds. He was watching his own future, seeing a life that revolved around Sallie as the center of existence. He saw her flashing in and out of his labora-tory as he worked, and whenever she entered, the whole room seemed to light up; whenever she left, he could scarcely work for the longing to follow.

He saw their first quarrel. Sallie, spinning in a shimmer of bright gla.s.s-silk as soft as gossamer, dimpled at the self which in this waking dream was more vividly Bill Cory than the Bill who watched. "See, darling, aren't I heavenly?" And he heard himself answering, "Edible, darling! But isn't that stuff expensive?"

Sallie's laughter was light. "Only fifteen hundred credits. That's dirt-cheap for a Skiparelle model."

He gasped. "Why Sallie, that's more than we're allowed for living expenses! I can't-"

"Oh, daddy'll pay for it if you're going to be stingy. I only wanted-"

"I'll buy my wife's clothes." Bill was grim. "But I can't afford Paris fashions, darling."

Sallie's pretty underlip pouted alarmingly. Tears sparkled in the soft brown eyes she lifted to his, and his heart melted almost painfully in one hopeless rush.

"Don't cry, sweetheart! You can keep it, just this once. But we'll have to make it up next month. Neveragain, Sallie, understand?"

Her nod was bright and oblivious as a child's.

But they didn't make it up. Sallie loved partying, and Bill loved Sallie, and nowadays there was much more hilarity than work going on behind the door in Biology House marked "Dr. William Vincent Cory."

The television's panels were tuned to orchestras playing strong rhythm now, not to lectures and laboratory demonstrations as of old.

No man can do two jobs well. The work on s.e.x determination began to strike snags in the path that had seemed almost clear to suc-cess, and Bill had so little time any more to smooth them out. Always Sallie was in the back of his mind, sweet, smiling, adorable.

Sallie wanted the baby to be born in her father's home. It was a lovely place, white-walled on low green hills above the Pacific. Sallie loved it. Even when little Sue was big enough to travel she hated to think of leaving. And the climate was so wonderful for the baby there- Anyhow, by then the Council had begun to frown over Bill Cory's work. After all, perhaps he wasn't really cut out to be a scientist- Sallie's happiness was more important than any man's job, and Sallie could never be really happy in Science City.

The second baby was a girl, too. There were a lot of girls being born nowadays. The telenews broadcasters joked about it. A good sign, they said. When a preponderance of boys was born, it had always meant war. Girls should bring peace and plenty for the new genera-tion.

Peace and plenty-that was what mattered most to Bill and Sallie Cory now. That and their two exquisite daughters and their home on the green Pacific hills. Young Susan was growing up into a girlhood so enchanting that Bill suffused with pride and tenderness every time he thought of her. She had Sallie's beauty and blondeness, but there was a resolution in her that had been Bill's once, long ago. He liked to think of her, in daydreams, carrying on the work that he would never finish now.

Time ran on, years telescoping pleasantly into uneventful years. Presently the Cory girls were growing up.

. . were married. . . were mothers. The grandchildren were girls, too. When Grandfather Cory joined his wife in the little graveyard on the sea-turned hill beyond the house, the Cory name died with him, though there was in his daughter's level eyes and in her daughter's look of serene resolution something more intrinsically Bill Cory than his name. The name might die, but something of the man who had borne it lived on in his descendants.

Girls continued to outnumber boys in the birth records as the gen-erations pa.s.sed. It was happening all over the world, for no reason that anyone could understand. It didn't matter much, really. Women in public offices were proving very efficient; certainly they governed more peacefully than men. The first woman president won her office on a platform that promised no war so long as a woman dwelt in the White House.

Of course, some things suffered under the matriarchy. Women as a s.e.x are not scientists, not inventors, not mechanics or engineers or architects. There were men enough to keep these essentially masculine arts alive-that is, as much of them as the new world needed. There were many changes. Science City, for instance. Impor-tant, of course, but not to the extent of draining the country dry to maintain it. Life went on very nicely without too much machinery.

The tendency was away from centralized living in these new days. Cities spread out instead of up.

Skysc.r.a.pers were hopelessly old-fashioned. Now parklands and gardens stretched between low-roofed houses where the children played all day. And war was a barbarous memory from those nightmare years when men still ruled the world.

Old Dr. Phillips, head of the dwindling and outmoded Science City, provoked President Wiliston into a really inspiring fury when he criticized the modem tendency toward a non-mechanized rural civili-zation. It happened on the telenews, so that half the world heard it.

"But Madam President," he said, "don't you realize where we're heading? The world's going backward!

It's no longer worth-while for our best minds to attempt bettering living conditions. We're throw-ing genius away! Do you realize that your cabinet yesterday flatly rejected the brilliant work of one of ourmost promising young men?"

"I do!" Alice Wiliston's voice rang with sudden violence over half the world. "That 'brilliant work,' as you call it, was a device that might have led to war! Do you think we want that? Remember the promise that the first woman president made the world, Dr. Phillips! So long as we sit in the White House there will be no need for war!"

And Elizabeth of England nodded in London; Julianna VII smiled into her Amsterdam telenews screen.

While women ruled, war was outlawed. Peace and ease, and plenty would dominate civilizatiou, leisure for cultivation of the arts, humankind coming into its own at last, after so many ages of pain and blood and heartbreak.

Years telescoped into centuries of peace and plenty in a garden world. Science had turned its genius to the stabilization of the climate so that nowhere was shelter necessary from cold or storms; food was freely abundant for all. The Garden that Adam and Eve forfeited in the world's beginning had returned again to their remotest descend- -ants, and the whole earth was Eden.

And in this world that no longer demanded the slightest physical effort, mankind was turning to the cultivation of the mind. In these white, low-roofed houses set among garden parks~, men and women in- creasingly adventured into the realms beyond the flesh, exploring the mysteries of the mind.

Bill Gory, leaning forward in his chair, had lost all ident.i.ty with himself. He was simply a consciousness watching time unfold before him. The gravestone that bore his name on the California hillside had long since sunk into the sod, but if there is immortality at all, Bill Cory watched himself move forward through the centuries, down the long, expanding line of his descendants. Now and again, startlingly, his own face looked briefly at him from some faraway child of his remote grandchildren. His face, and Sallie's.

He saw pretty Sue come and go like reflections in a mirror. Not always Sue unmistakably and completely-sometimes only her brown eyes lighted the face of a many-times-great-granddaughter; sometimes the lift of her smile or the tilt of her pretty nose alone was familiar to him in a strange face. But sometimes Sue herself, perfect to the last detail, moved through the remote future. And every time he saw those familiar features, his heart contracted with an ache of tenderness for the daughter he yet might nevet have.

It was for these beloved Susatis that he was becoming uneasy as he watched time go by in this lazy paradise world. People were slowing mentally and physically. What need any more for haste or trouble?

Why worry because certain unimportant knowledge was being lost as time went on? The weather machines, the food machines were eter-nal; what else really mattered? Let the birth rate decline, let the dwindling race of the inventive and the ambitious fade like the anachronism it was. The body had taken mankind as far as it could; the mind was the vehicle for the future. In the vast reaches of infinity were fields aplenty for the adventurous spirit. Or one could simply drowse the days away- Clouds thickened softly across the dreamy vistas of Eden. Bill Cory leaned back in his chair and rubbed his eyes with both hands. The hands were shaking, and he stared at them a little stupidly, still half lost in the wonder of what he had seen, in the strange welter of emo-tions that still warred in him-the memory of Sallie and his strong love for her, the memory of Sue's sweetness, the memory of pride in them both. And in the queer feeling that it had been himself in those many daughters of his through the ages, striving so hard for world peace to the ultimate end that mankind might achieve-ruin.

For it was wrong-it was bad. The whole world. The race of man was too splendid, too capable of working miracles, to end on a myrtle bank dreaming about abstractions.

He had just seen a decadent, indolent, civilization going down the last incline into oblivion as a result-yes, as a direct result-of his own action. He'd seen himself sinking into a fat, idle old age, without honor of achievement.

Suddenly and desperately he hoped that Ashley had been right- that this was not the inevitable and changeless future. If he tore up the letter lying on his desk now, if he never married Sallie, would not his work be finished successfully some day, and the catastrophe of un-balanced births avoided? Or could a man change his ordained future?Almost fearfully he reached for the letter lying beside that clouded cube in which the years had mirrored themselves. Would he be able to take the letter up and rip it across-like this? The sound of tearing paper rea.s.sured him. So far, at least, he was still a free agent.

And knowing that, suddenly he was sorry. Not to marry Sallie, with her bubbling laugh. Never to see young Sue growing into beauty and courage and sweetness. Old age without achievement, had he said to himself a moment ago? Sue herself was achievement enough for any man. Sue and those other Susans down the long line of his descend-ants, incarnating again and again all that was finest in him, eternal as life itself through millenniums.

He did not want to meet again the brown eyes of this latest Susan who had come to him in the depths of the cube. While he laoked, his reason was lost in his love for her, and not even against reason could he believe the world which had produced her to be anything but per-fect, simply because this beloved daughter moved and breathed in it.

But the letter was torn. He would never marry Sallie if he could help himself. The cost was too high, even for such a reward as Sue. And an almost tremulous awe broke over him in a sudden tide as he realized what he was doing. This was what Ashley had dreamed of- opening a window into the Plane of Probability and learning enough to force the Cosmic Mind out of its course. Changing the shape of his own future and that of all mankind. Greater than G.o.ds-but he was no G.o.d. And Ashley had warned him that it might be dangerous to usurp a G.o.d's prerogative. Suddenly he was afraid.

He looked away from that cube which held his future, and across from it on his desk the violet eyes of Marta Mayhew caught his, fixed in their changeless smile. She was a girl, he thought, he remembered from half a lifetime ago, so much had happened since he glanced last into her face. Dark and lovely she was, her eyes meeting his almost as if there were vision behind their deep, long stare. Almost as if- Light flared out in one white, blinding sheet that blotted out the cube and the violet-eyed face and the room around him. Involuntarily Bill clapped his hands to his eyes, seeing behind the darkness of his lids a dazzle of blurring colors. It had happened too quickly for wonder-he was not even thinking as he opened his eyes and looked into the cube where Marta's gaze had met him a moment before.

And then a great tide of awe and wonder came washing up into his consciousness, and he knew that Ashley had been right. There was an alternative future. There comes a point beyond which bewilderment and shock no longer affect the human brain, and Bill was outside wondering now, or groping for logical explanations. He only knew that he stood here staring into the cube from which Marta's eyes had smiled at him so short an instant ago- They were still Marta's eyes, deep-colored in a boy face almost Bill's own, feature for feature, under a cap of blue steel. Somehow that other future had come to him, too. He was aware of a sudden urgent wonder why they had come so nearly together, though neither could be conscious of the other- But things were moving in the depths of the cube.

Behind the boy's face, three-dimensional perspective had started vividly back from the crystal surfaces, as if the cube were a wide win-dow flung suddenly open upon a new world. In that world, a place of gla.s.s and shining chromium, faces crowded as if indeed at an open window, peering into his room.

Steel-helmed faces with staring eyes. And foremost among them, leaning almost through the opened win-dow into his own past, the steel-capped boy whose features were Bill's looked eagerly out, the sound of quickened breath through his lips a soft, clear sound in the room. They were Bill's lips, Bill's features- but Marta's gentle courage had somehow grown masculine in the lines of the boy's face, and her eyes met Bill's in his.

In the instant before those parted lips spoke, Bill knew him, and his throat closed on an unuttered cry of recognition-recognition of this face he had never seen before, yet could not mistake. The deep welling of love and pride in his heart would have told him the boy's ident.i.ty, he thought, had he not known at sight who he was-would be-might one day be- He heard his own voice saying doubtfully, "Son-?"

But if the boy heard he must not have understood. He was hand-icapped by no such emotion as stirred Bill. His clipped, metallic voice spoke as clearly as if indeed through an opened window: "Greetings from the United World, William Vincent Cory! Greet-ings from the Fifteenth Leader in the Fifth New Century, A. C."

Behind the disciplined, stern-featured young face others crowded, men with steel-hard features understeel caps. As the boy's voice paused, a dozen right arms slanted high, a dozen open palms turned forward in a salute that was old when Caesar took it in ancient Rome. A dozen voices rolled out in clipped accents, "Greetings, William Vincent Cory!"

Bill's bewildered stammer was incoherent, and the boy's face relaxed a little into a smile. He said: "MTe must explain, of course. For generations our scientists have been groping in the past, Dr. Cory. This is our first successful two-way contact, and for its demonstration to our Council, connection with you was selected as the most appro-priate and fitting contact possible. Because your name is holy among Us; we know all there is to know of your life and work, but we have wished to look upon your face and speak to you of our grat.i.tude for molding mankind into the patterns of the United World.

"As a matter of record, I have been instructed to ask first at what point we have intersected the past.

What date is it in your calendar?"

"Why, it's July 7, 2240," Bill heard his own voice stammer a little as he answered, and he was conscious of a broad and rather foolish grin overspreading his face. He couldn't help it. This was his boy-the child who wouldn't be born for years yet, who might, really, never be born. Yet he knew him, and he couldn't help smiling with pride, and warm, delighted amus.e.m.e.nt. So stern-faced, so conscious of his own responsibility! Marta's son and his-only of course it couldn't be, ex-actly. This scene he looked into must be far ahead in time- "Twenty.two forty!" exclaimed the boy who was not his son.

"Why, the Great Work isn't even finished yet then! We're earlier than we knew!"

"Who are you, son?" Bill couldn't keep the question back any longer.

"I~m John Williams Gory IV, sir," said the boy proudly. "Your direct descendant through the Williams line, and-First in the Can-didates Cla.s.s." He said it proudly, a look of almost worshiping awe lighting his resolute young face. "That means, of course, that I shall be the Sixteenth Leader when the great Dunn retires, and the sixth Cory-the sixth, sir!-to be called to that highest of all human sta-tions, the Leadership!" The violet eyes so incongruous in that dis-ciplined young face blazed with almost fanatic exaltation.

Behind him, a heavy-faced man moved forward, lifting the Roman salute, smiling wintrily beneath his steel helmet.

"I am Dunn, sir," he said in a voice as heavy as his features. "We've let Candidate Cory contact you because of the relationship, but it's my turn now to extend greetings from the System you made possible. I want to show it to you, but first let me thank you for founding the greatest family the United World has ever known. No other name has appeared more than twice on the great role of Leaders, but we have had five Corys-and the finest of them all is yet to come!"

Bill saw a wave of clear red mount his boy's proud, exalted face, and his own heart quickened with love and pride. For this was his son, by whatever name he went here. The memory of his lovely daughter had been drowned out momentarily in the deep uprushing of pride in this tall, blue-eyed boy with his disciplined face and his look of leashed eagerness. There was drive and strength and power of will in that young face now.

He scarcely heard Dunn's heavy voice from the room beyond the cube, so eagerly was he scanning the face of this son he yet might never have, learning almost hungrily the already familiar features, at once hard and eager and exultant. That mouth was his, tight and straight, and the cheeks that creased with deep hollows when he smiled, but the violet eyes were his mother's eyes, and the gentle inflexibility of Marta's courage at once strengthened and softened the features that were Bill's own. The best of them both was here, shining now with something more than either had ever known-an almost fa-natic devotion to some stem purpose as exalting as worship, as inflexi-ble as duty- "Your own future, sir,"

Dunn was saying. "But our past, of course.

Would you like to see it, Dr. Cory, so that you may understand just how directly we owe to you all that our world is today?"

"Yes-v-very much." Bill grinned at his own stammer, suddenly light-hearted and incredulous. All this was a dream. He knew that, of course. Why, the very coincidences in it proved that. Or-were they coincidences? Desperately he tried to clarify the thought taking form in his own mind, a terrifyingly vastthought, terrifyingly without ex-planation. And yet it must be a dream- If it were real, then there was more than chance here. It could be no accident that these two children of his, groping blindly in the dark for contact with him, had succeeded at so nearly the same moment. There would be reason behind it, reason too vast for comprehension. He parted his lips to speak, but Dunn was already speaking.

"Look then, William Vincent Gory! Watch your own greatness un-folding in the years that lie ahead."

Hazily the scene in the cube blurred. The beloved, blue-eyed face of the boy he might never have, faded as a dream fades-a dream fading in a dream, he thought dimly- This time it was Marta coming down the church aisle toward him, looking like a violet-eyed madonna coifed and veiled in white lace. He knew that he did not love her, now. His heart was still sore with the memory of Sallie. But love would come; with a woman like this it could not but come. There was tenderness and humor and pa.s.sion on that raptly lifted face, and a strength that would call out the strength in him, not a weakness such as dimpled in Sallie's face to evoke an un-derlying weakness in himself. For weakness was in him. He knew it. It would depend upon the woman who shared his life which quality overcame the other.

Life would be good with Marta. He saw it unfolding before him in a long succession of days, work and play and companionship that brought out the best in both. And the memory of the strange vision in which he thought he loved Sallie faded. This was the woman he loved. Her courage and humor, her violet eyes bright with pride of him- Life went by-clear, condensed, swift. He saw his own work moving steadily toward success, Marta's eager encouragement tiding him over the low ebbs when difficulties threatened. She was so full of pride in her brilliant young husband that her enthusiasm almost ran away with her. It was she who insisted upon making the discovery public.

"I want to flaunt you before the world!" she urged. "Let's report to the Council now, darling. Aw, please, Bill!"

"MTe're not ready yet," he protested feebly. "Let's wait-"

"What for? Look." She shook a record sheet under his nose. "A hundred per cent success in the last dozen experiments! What more do you want? It's time to make an official report-announce what you're doing to the world! You've been all the way from fruit flies to monkeys. You'll have to make a report to the Council anyhow before you can take the next step. And remember, darling, when you come to that, I'm first in line as a candidate."

He seized her shoulders in a heavy grip, frowning down into the eagerness of her lifted face. "There'll be no guinea pigs in this family! When Junior Cory comes into the world he-or she-will do it without benefit of X-rays. Understand?"

"But darling, I thought the whole idea was to give parents their choice of boys or girls in the family."

"The thing's not perfected yet to the point where I'd want to risk my own wife. And anyhow . . .

anyhow, I've got a funny notion I'd rather just take what comes. Don't know why, exactly, but-"

"Bill, I do believe you're superst.i.tious! Well, we'll fight that out later. But right now, you're going to make a full report of your success to the Council, and I'm going to be the proudest wife in the City. And that's final!"

So the report was made public. It created a tremendous furor; the world clamored for the magical stuff that would put the molding of the future into their hands. Bill Cory blushed and grinned for a delighted public in the telenews screens, promising the great gift soon, and Marta glowed with vicarious pride.

By the time he had made his first experiment with a human subject, the puppies which were the result of his first successful mammalian experiment were beginning to worry him a little. Miss Brown was the first to notice it. She came in from the kennels one day with a frown behind her steel-rimmed spectacles.

"Dr. Cory, has someone been training those dogs?"

"Training them?" Bill looked up, puzzled. "Of course not. Why?"

"Well, they've got the makings of the finest trained dogs on Earth. Either the whole lot of them is exceptionally intelligent or . . . or something. They just fall over each other obeying every com-mand you can make clear to them."

Bill straightened from his microscope. "Urn-rn-rn - . . funny. Usually one or two dogs in a litter are more intelligent and obedient than the rest. But to have every one in six litters a canine genius is somethingpretty queer. What do you make of it?"

"I wouldn't call it genius, exactly. As I say, I'm not sure if it's un-usual intelligence or. . . well, maybe a strong strain of obedience, or lack of initiative, or. . . it's too soon to say. But they're not normal dogs, Dr. Cory."

It was too soon to say. Tests simply showed the pups to be extraor-dinarily amenable to training, but what quality in them made this so was difficult to determine. Bill was not sure just what it implied, but an 'uneasiness in him woke and would not be quieted.

The first "X-ray" babies began to be born. Without exception they were fine, strong, healthy infants, and without exception of the prede-termined s.e.x. The Council was delighted; the parents were delighted; everyone was delighted except Bill. The memory of those oddly obedient pups haunted him- Within three years the Cory System was available to the public.

The experimental babies had made such an excellent showing that, in the end, Bill gave in to the insistent world, though something in the recesses of his mind urged delay. Yet he couldn't explain it. The babies were all healthy, normal, intelligent children. Unusually amenable to authority, yes, but that was an a.s.set, not a liability.

Presently all over the world the first crops of Cory System babies began to appear, and gradually Bill's misgivings faded. By then Bill Junior had arrived to take his mind off other people's childr~nr but even now he was obscurely glad that little Bill was a boy on his own initiative, not because his parents had forced masculinity upon him. There was no rhyme or reason to Bill's queer obsession that his own child should not be a product of the X-ray system, but he had been firm about it.

And in later years he had reason to be glad. Bill Jr. grew up fast. He had Marta's violet eyes and his father's darkly blond hair, and a laughing resolution all his own. He was going to be an architect, and neither his mother's shocked protest at this treason to the family pro-fession, nor Bill's not wholly concealed disappointment could swerve him. But he was a good lad. Between school terms he and his father had entirely marvelous vacations together, and for Bill the world revolved about this beloved, talented, headstrong youngster whose presence upon Earth seemed reason enough for Bill's whole existence.

He was glad, even, that the boy was stubborn. For there could be no question now about a weakness in the children of the Cory System births. In all ways but one they were quite normal, it was true, but ini-tiative seemed to have been left out of them. It was as if the act of predetermining~'their s.e.x had robbed them of all ability to make any decisions of their own. Excellent followers they were-but no leaders sprang up among them.
