"Everything's simplifying," Bill went on, as if he had not heard. "Even his bones. Even his ribs. They give like a child's ribs, half cartilage. I got to thinking, you know, after I saw that. I gave him a basal, just on a hunch, and he's plus forty. His thyroid is burning him up. But Pete, it doesn't seem to hurt him! No loss of weight, no increased appetite, sleeps like a baby—why, my nerves are twice as jumpy as his."
"But—that's impossible."
"I know."
Silence. Then, "Anything else wrong?"
Bill shrugged helplessly. "I don't know. I was afraid to run any more tests on him after that. It's the truth, Pete—I was afraid to."
Morgan put the last plate down very gently, and turned his back on the table. For the first time there was uncertainty in his motions. He was no longer a man supremely sure of himself. He said, in an indecisive voice, "Yeah. Well, we'll start tomorrow and give him a thorough going over. I ... I think maybe we can find what's—"
"It's no use, Pete. You see that. We've started something we can't stop. He's gone too far along the river, and the current's got him. All the basic life processes that move so fast in youth are moving in him now faster than we can move. God knows where he's going—not back along any path a man ever heard of before—but he's into the current and we can't do a thing about it."
And after a moment Morgan nodded. "You were right," he said. "You've been right all along, and I've been wrong. Now what?"
Bill made a gesture of futility. "I can't tell you. This is still your party, Pete. I'm just along for the ride. I saw the dangers first because ... well, maybe because Rufus is my own kin and the pull was ... tangible ... between us. When he went off beam I could feel it psychically. Could that explain anything?"
Morgan sat down with a sudden limpness, like a man whose muscles have abruptly gone weak. But his voice, after a moment's bewilderment, began to grow firm again.
"It's up to us to find out. Let's see." He shut his eyes and rubbed the closed lids with unsteady fingers. There was another silence. Presently he looked up again and said, "He's been changing from the very first. I suppose I've been assuming that something in our treatment had shuffled his chromosomes and genes around into a new pattern of heredity, and he was beginning to throwback to some ancestor we never knew about. But now I wonder if—" He paused, and a startled look crossed his face. He stared at Bill with eyes that widened enormously. "Now I wonder—" he echoed tonelessly, as if his lips repeated something meaningless, while his mind raced ahead too fast for utterance.
After that he got up with a sudden, abrupt motion and began to pace the floor, his steps rapid. "No," he murmured, "that's crazy. But—"
Bill watched him for a moment or two longer. Then he said in a quiet voice, "I had the same idea quite awhile ago. I was afraid to say anything, though."
Morgan's head jerked up and he stared. Their eyes held in a long look, awe in Morgan's. "That they were shuffled—too much? The chromosomes could have fallen into a pattern—too different?"
"You saw the X-rays," Bill said gently.
"Let's have a drink," was all Morgan answered to that.
-
When they were settled again, and there was something very soothing and matter-of-fact about the tinkle of ice in their glasses, Morgan began in a voice that strained a little for the prosaic.
"There may be a race that looks like Rufus. Or there may once have been. No use jumping at the impossible before we exhaust normal possibilities. I've been trying to think of any race at all with just his facial characteristics, and there isn't one on earth today, but that's not saying there never has been. No race sprang full-blown into the world, you know. You and I must have had remote ancestors who lived on Atlantis, or were contemporaries of the Atlanteans anyhow. And who knows what they looked like?"
"You keep forgetting," Bill reminded him, still gently. The X-rays. And this may be only the beginning. He'll move faster and faster now. Physiological time is fast—terribly fast—as it nears the source. Do you think there was ever a race like Rufus—inside?"
Morgan looked at him over the glass rim. He caught his breath to say something forcefully, then let it out in a sigh. "No. I don't think there ever was. Not here."
"All right," Bill said. "You take it from there."
"How can I?"
"Try. I'm afraid to. My ideas are too ... too credulous. I'm curious to see if your mind follows the same track. Go on—take over."
"He's a ... a changeling," Morgan began, groping. "There've been stories about changelings for a long time. Older than the Faustus legend. I wonder, was Faust a changeling too? Did he have the same potential trace of heredity that a time-reversal could make dominant? Changeling ... fairy's child ... fairies? Fragile people, invisible at will, built to another scale than ours—another dimension? Other dimensions, Bill?"
Bill shrugged. "He can't eat what we eat. If these changes go on, there won't be a food on earth he can digest. Maybe, somewhere, there is—"
Morgan said abruptly, "Maybe the changes won't go on, either. We don't know they will. Are we making fools of ourselves, groping around in fairy stories for an answer we may not need?"
"I think we'll need it, Pete. Anyhow, let's go on and see what we get. Another dimension, you were saying—"
"O.K., suppose there were changelings," Morgan said violently. "Suppose there are goblins and things that go bump in the night—"
" 'Good Lord, deliver us,' " Bill finished the quotation with a grin. "Use a little logic, Pete. I don't expect you to believe the pumpkin turned into a coach. But if we apply the alchemist's formula to the changeling idea, or the Faust legend, do we get anything at all?"
"Oh, that isn't so new. It's been suggested before that the supernatural beings of legend might be distorted memories of some other-dimensional visitors. But Rufus—"
"All right, Pete, say it."
With an air of deliberate sacrifice, Morgan lifted his black-mustached lip in a snarl and said, "Rufus may be—he appears to be—an hereditary throwback to some inhabitant of another world. Is that what you want?"
"It'll do."
"It explains—" Morgan suddenly glowed with an idea that justified his sacrifice. "It explains his reaction to the picture of his mother. It explains why things look wrong to him here. It even explains his impossible memories, in part."
Bill looked doubtful. "Yes—in part. There's something more, Pete. I'm not sure what—I just know this isn't all. It's not quite so easy. The clock, and the calendar, if that's what the chessboard is—yes, you could say he senses a different time-scheme from ours and he's groping to recapture something familiar from some other life-experience he can't quite remember yet. But there's something more. We'll know it before we're through, Pete. He's on his way back now. I'm scared. I don't want to know about it. My mind panics when I think of it. It's too close to me. But we'll know. We'll find out. We haven't got to the root of the thing yet, but when we do we'll see it isn't as easy as all this."
"The root? I wonder. There's one thing, Bill. Rufus wasn't like this during his normal growth-period. You remember what we were discussing once about the possibility of aberrations at birth that smoothed out in adolescence? He could be experiencing now the results of disturbing that adjustment. But you can't mutate backward. It simply isn't remotely conceivable, by any application of logic, on this or any other world. You can say he's inherited a potentiality of Martian or other-dimensional chromosomes, but that still won't explain it. Mutation is a ... a spreading out, a flowering, not a drawing in. And that must hold good anywhere in this—" He stopped, his heavy brows drawing together. After a while, he began again, gropingly.
"I'm wrong on that. It ... let's see. It holds good only as long as there's the same temporal constant. And that's just what doesn't apply to Rufus."
Bill scowled. "He's going back in time, but it's all subjective, isn't it?"
"It started out that way. Could be the subjective's affecting the objective."
"That Rufus is warping time?"
Morgan was not listening. He had found pencil and paper in his pocket and was absorbing himself in meaningless squiggles. The heavy moments moved past. The pencil point stopped.
Morgan looked up, his eyes still puzzled. "Maybe I've got it," he said. "Maybe. Listen, Bill—"

In a railroad yard there are many tracks. Each track carries a train, moving forward relentlessly in space—and parallel.
According to the theory of parallel time, each train is a spatial universe, and the tracks are laid on the dark roadbed of time itself. Far, far back, in the black beginning, there may have been one track only, before it branched.
As it branched and branched again, the parallel roads spread out, forming in little groups—the New York Central, the Pennsylvania, the Southern Pacific and the Santa Fe. The trains—the universes—of each are roughly similar. The Penn has many cars rushing headlong through the dim mistiness of time, but they all contain recognizable variations of homo sapiens. The tracks branched, but the system is still a unit.
There are other units.
One thing they have in common—no, two things. They are parallel in time, and originally they came from the same unthinkable source, hidden in the mind-staggering, vast mysteries of the womb of space and time. In the beginning—
But you can't go back to the beginning. You can't even go back along your timetrack. Because the train is moving on, it isn't where it was twenty, fifty, eighty years before, and if you try to retrace your steps, you're walking along a strange road. It isn't quite spatial or temporal, really. It may involve—well, call it a dimension—that's so remarkably alien to us that we can't even conceive of it except as a—difference.
But it may be a bridge, a shortcut, this strange road the traveler finds when he tries to retrace time. It may be a tightrope stretched precariously between parallel timetracks. The letter n expresses it. The vertical lines are the timetracks where the trains go by. The angled line is the shortcut—from the Penn to the New York Central.
Different companies. Different lines. Different—groups.
So you can't recapture your youth; you can't go home again; that home isn't there any more. It's away back along the track, lost in the dusk where the dead ashes of Tyre and Gomorrah have smoldered out.
And it isn't just a matter of chromosomes. Not merely subjective. But going back, at an angle, into one of the parallel times where a certain equivalent of Rufus Westerfield existed.
Parallels do not imply similarity—not when the cosmic equations are involved. The basic matrix may not vary, but only a god can recognize such an ultimate basic. The mammal matrix, for example. Whales and guinea pigs are each mammalian.
So there were, perhaps, many equivalents of Rufus Westerfield, in the infinity of trains along the infinity of tracks—but he was not retracing his course along the Pennsylvania line.
The New York Central line was—parallel—but only on the Penn road were tickets sold to homo sapiens.
-
Rufus Westerfield was twenty-five. He lay at full length in the porch swing, somnolent in the hot July afternoon. One arm was behind his head and he tugged at the support-chain now and then to keep himself in lazy motion.
Laziness, indeed, was his keynote at this stage. Which seemed odd in contrast with the keen, humorous face so subtly unlike his face of forty-odd years ago, when he had once before been twenty-five. You would still have known at a glance that Rufus and Bill were closely related; the change was too subtle to alter that. But there was a sharpening of all the features now, a more than physical sharpening. And the contradictory indolence of him made Rufus look arrogant.
It was, given this outrageous set-up, a normal indolence, but it went curiously with the youth of the man. At twenty-five a mind as keen and a face and body as forceful as Rufus' should have had no indolence about them. But at twenty-five the normal man is just entering upon the most productive period of his life. All through adolescence he has been building impatiently toward this fulfillment of his maturity.
But there had been nothing immature about Rufus Westerfield's immediate past. And life was not before him. The swift temporal current flowed away past him and out of sight. He moved toward the helplessness of infancy, not to the activity of his prime. And each day that went by was longer and more pellucid to him than the last. As the physical processes of his body moved faster and faster, so the temporal processes of his mind went slower. The thoughts of youth, wrote Longfellow, are long, long thoughts.
Rufus put out his free hand and deftly took up a glass from the porch floor as the swing lifted him toward it. Ice tinkled pleasantly; it was a rum collins, his fifth today. He watched the flicker of leaf-shadows on the porch roof and smiled comfortably as he sipped the sweet, strong liquid, rolling it upon his tongue. Taste was developing more and more keenly in him as the years retrogressed. The infant's whole mouth is lined with taste buds, and in Rufus' mouth, little by little, those taste buds were returning.
He had drunk a good deal in the past two months. Partly because he liked to drink, partly because alcohol was one of the few things his changing digestion would tolerate. And it helped to blur that nagging sense in him which he could not put a name to, the feeling that much he saw about him was indescribably wrong.
Rufus was an intelligent young man. Also he was tolerant. He saw no point in letting the sense of wrongness color his life unduly. He dismissed it when he could. In part this was simply an admirable adjustment to environment. It was a great pity that the man through whose changing phases Rufus moved so rapidly must remain only half known. He would have been a fascinating man, with his memories and mature wisdom accumulated over seventy years, his vigorous mind and body, and the sardonic keenness, the warmth and humor developing in him now. And with all these the enthralling subtleties of change from no source a man ever drew upon before. He was a blend, perhaps, of human and extra-human, and perhaps the best of each, but no one would ever know him wholly. The man he might have been was moving too swiftly for more than a glimpse at the life he might have lived. The stream that bore him along could not run slowly.
In part, then, it was a tolerant adjustment to life that let him accept what was happening so calmly. But it was also a form of precociousness in reverse. Because he was keenly intelligent, he would normally—at twenty-five going on twenty-six—have been in advance of his years. His brain would have fitted him to cope successfully with men many years his senior. And now, at twenty-five going on twenty-four he was still in advance of his age. But in reverse. In Rufus, it was efficiency that his mind was slowing leisurely toward the long thoughts of youth. It spared him a great deal.
The pleasant blur of drunkenness had another effect, too. It released the surface tension of his mind and let strange flotsam drift upward. Memories and fragments which he knew had no place in the past he had already lived. Knowing it, he made no effort to reconcile the paradox. More and more as time went by he approached that period when the individual questions only the superficial aspects of his world. Basically, he accepts it, turning trustfully to the protection of those around him. And in Rufus, his very intelligence forced him backward prematurely into that state of mind which belongs to childhood, because it was in that state that he could find the greatest protection from a peril his subconscious must have sensed and would not let the surface of his mind suspect.
On the surface, memories from two pasts floated and merged and sank away again, lazily, evoked by alcohol. In the beginning, memories of that other past had been thin as smokewreaths drifting transparently across the face of his clearer remembrance, indistinguishable from realities. It was a long time before he became consciously aware that two sets of memories, many of them mutually exclusive, were moving at once through his mind. By the time he was sure, he had passed beyond the stage of caring. Things beyond his control were happening with inexorable rhythms that carried him smoothly toward a goal he did not try to glimpse yet; it woul
d come in good time, he could not miss it, he was ready.
Now the memories from that other past were superimposed over nearly all his Westerfield memories. He looked back upon Westerfield years more dimly, through a haze of obscuring events that did not seem in the least strange to him, and no more alien than his remembrances of Bill's youth, and of his long-dead wife. He could no longer distinguish at a mental glance which memory belonged to the Westerfield period and which to the other. But they had been different. Very different indeed. Individuals moved past and through his memories of Bill and Lydia, individuals whose names he knew but could not yet pronounce, beings who had played tremendous roles, perhaps, in that other past, in that other place.
But they too were veiled in this all-encompassing indifference which was his protection and his precociousness. Like the Westerfields, they belonged to an era that was moving too fast to be savored much. He had not time to spare for leisurely evocations of the past.
So he remembered, pleasantly, not questioning anything, letting the liquor release the double stream of memories and letting the memories glide by and go. Faces, colors, sensations he did not try name, songs—like the song he was singing under his breath, now, to the slow rhythm of the swing.
-
Bill, coming up the steps, heard the song and tightened his lips. It was no tune at all. It was one of the nagging, impossible harmonies Rufus hummed so constantly, not really knowing that he did it. The words were not English, when he sang them in absent-minded snatches, and the melody was more alien than the cacophonies of oriental music. Bill had given up trying to understand. He had given up a great deal in the past month, since it became obvious that Rufus was going on beyond the thirty-five which was to have been his stopping point. Bill had met failure halfway and acknowledged the meeting with what equanimity he could summon. There was nothing to salvage now but sufficient grace to confess defeat.
Rufus in the swing seemed half asleep. The lids were lowered above the tilted black eyes, and the face had no expression beyond indolence. It worried Bill that although this was not a Westerfield face any more, it remained akin to his own. Again and again of late he felt with unreasoning discomfort that as Rufus changed in feature, he pulled Bill's own features awry to conform. It was not true, of course, the change was indescribably outside the mere matter of facial angles, but the effect remained disconcertingly the same.
