Then Uncle Andy said, "I think we'd better try it."

Valerie grasped his hand and Martia's. "Let's all go through together,"

she suggested, quietly.

They drew close to each other, held hands, and formed a straight

line of five as they walked through the mirror together--just as the

corridor behind them filled with light again and a pair of bloodshot

eyes noted their departure....

* * * * *

This was definitely a tremendous, subterranean city, or the beginning

of one. But its only inhabitants, other than the alien, seemed to

be the survivors of MATS flight 702. They were still in a state of

hypnosis, standing there on the pillared mezzanine that overlooked the

vast room below and beyond them. Other mezzanines were visible on the

far side of that tremendous chamber, and beneath them a dozen or so

tunnel entrances indicated that there was much to be seen further on.

Among the people who stood out there on the mezzanine were Pee Bee

and Scarface, also in a trance, as well as the Texas GIs, the missing

WAACs, Martia's governess, Emily, the two mothers, Mr. Langham, Sir

Rollins--and Lady Dewitt.

Martia might have cried out and run to her mother were it not for the

fact that the alien, himself, confronted them.

They stood in an alcove that was half filled with banks of controls and

instruments. The alien stood before these controls and glared at them

purposefully as they came through the teletransmitter. His neck was

dark with dried blood, and the three arrows still protruded from his

side. His stooping posture gave more evidence than before that he was

growing weaker.

As they came through and caught sight of him and the others, one of his

hands moved on the control panel, then paused.

_Don't do that!_--came a sharp command into his mind.

He straightened up suddenly, his single eye brightening in shocked

surprise as he looked first at Henry, then at Martia.

Valerie, Peggy and Uncle Andy watched the alien, white-faced,

uncomprehendingly, as he slowly turned to face them squarely, his

eye fairly glittering with inner lights of its own. Then--without

warning--he uttered a few unintelligible words, groaned, and fell on

his face.

"Quick!" said Uncle Andy. "The gun!" He ran, himself, to pluck it out

of Scarface's nerveless fingers.

"But what happened!" exclaimed Valerie. "Is he dead?" She and Peggy did

not follow Henry and Martia as they went over to look at the alien.

"Henry," whispered Martia. "What _are_ we? I know what you did!"

Henry paused to look at her. "Martia, Lady Dewitt is not really your

mother--_is_ she?"

Martia colored.

"You know there are no secrets between us," he insisted.

"No," she answered. "I am an orphan, like you."

"An orphan equipped with photographic memory and extra-sensory

perception," he said, rapidly. "Also, other things, like extended

perception in time. You have lately come to sense that your mind was

'fixed,' long ago, to keep you from using your full powers and to

prevent you from knowing who or _what_ you were, but these recent

experiences have started an awakening process--"

"Yes!" she agreed. "Henry, what--"

His eyes bored into hers, his nostrils flaring in his tense excitement.

"Shall I tell you where you were really born?" He turned his head and

looked down. "Wait! He's beginning to stir! _He_ can give us the final

answer!"

As the alien stirred, one of the tendrils on his wrist twirled a

control on the panel at his waist. Martia swayed, but Henry stood his

ground, blocking that telepathic signal and showing Martia how to do it

at the same time. But Valerie and Peggy and Uncle Andy dropped to the

floor, unconscious.

The alien rose slowly to his feet, and Henry turned, instinctively, to

get the gun that Uncle Andy had dropped. Then he and Martia, as well as

the alien, stiffened in surprise as Scarface smilingly picked up the

gun and leveled it.

"Everything is going to be all right," he said, confidently. "I think

I have all the answers now. It was not the impossible coincidence I

imagined it to be, his coming upon all three of us on board that plane.

I think that he--"

"Look out!" screamed Martia.

Out of the mirror had come an unexpected figure, hurling itself upon

Scarface's back. Scarface went down and the gun was torn from his

fingers, even as the alien reached for his controls on the instrument

panel behind him.

"No you don't!" yelled Tommy Weston.

He stood there, his clothes half torn off, supporting himself on one

good leg and painfully trying not to bring pressure to bear on the

other, which appeared to be sprained.

"I'm _still_ running the show!" he yelled, hysterically.

_Quick!_--came a thought from Scarface to the two adolescents. _Through

the teleporter!_

As they literally threw themselves into the silvery mirror in back of

them, they heard Weston firing shot after shot into the alien....

* * * * *

Back in the subterranean chamber where they had come upon their first

teleporter, Scarface reached behind the mirror and adjusted something,

whereupon the sheet of silvery substance took on a bluish sheen.

"You see, I knew all along what this was," he said. "But if I had told

you that it would probably lead you right into Mlargn's hands you would

not have dared follow. You needed one more shock to bring you out, and

I waited there for you, waiting for my final proof." He smiled. "In his

weakened condition, it was too _much_ of a shock to Mlargn. I didn't

quite expect him to pass out like that--the poor beast! Well, anyway,

Weston has taken care of him, and this adjustment will keep him from

following us."

"Wait, please!" interrupted Henry. "You're assuming too much knowledge

on our part. We--"

"Just one more detail," said Scarface, as he made a last adjustment

behind the mirror. By now it was a shimmering pink. "Follow me," he

directed. And without further explanation he stepped _back_ through the

teleporter.

Under ordinary circumstances, Henry and Martia would have reacted

emotionally to this new development, and fear would have restrained

them. But this was a very special circumstance because they had had an

awakening. A calm logic told them that Scarface would not have directed

them to follow him if it would do them any harm. One of the premises

of that logic was that they had "read" at least his attitude. He was

definitely an ally--and the ultimate answer to their mutual enigma.

So they followed him.

They found themselves in a great, domed citadel which covered the

entire top of a small island. Some miles away was a long stretch of

jungle-covered land and low hills easily recognizable as the country

where they had first camped. They could even make out the silvery

glitter of the wrecked plane.

They remembered having seen this island from the shore, but it had

looked like a flat-topped, barren rock protruding from the sea. Then it

came to them that the citadel on top was invisible from the land.

Scarface sat at the console of a tremendous instrument panel. On his

head was an elaborate headpiece equipped with silvery anodes that

clamped against his skull. His eyes were closed. His fingers made

delicate adjustments on the console while strange, almost ultra-sonic

tones emanated from a battery of glowing tubes on the wall.

Martia and Henry sensed that they were not to disturb him. So they

walked around inside the dome and looked at the sea, and the old, old

land. Their minds were awakening to new perspectives and powers, and

slowly they caught glimpses of a billion year pattern of destiny that

dazzled their thoughts. So they barred these perspectives, holding them

breathlessly at the threshold of soaring consciousness--waiting for

experienced guidance.

At length, Scarface finished his task and came over to them. "While I

am waiting for results," he said, "I will tell you what you want to

know...."

* * * * *

He told them that somewhere in the era of time in which they had been

raised, a cataclysm had occurred which had destroyed all life on Earth.

Oceans had come over the land and the whole, slow, geo-biological

process of regeneration had begun once more. Evolution through hundreds

of millions of years had at last arrived at a dominant, intelligent

species of which Mlargn, the "alien," was the last survivor.

He told them the story of Xlarn, of the cooling of the sun, of

the reaction sphere, and of the Chronotron. And he described the

developments which finally led to Mlargn's time journey in search of

life before the Beginning.

"Actually, Mlargn made two trips into Earth time. On his first trip

he must have arrived somewhere in an earlier century than the one you

knew--"

"The thirteenth century," interrupted Henry.

Scarface looked at him in wonderment. So both Henry and Martia told him

the legend of the Pied Piper of Hamelin.

For almost a minute, the other was silent. Then he said, "So that's

where the ancestors of Galactic Civilization came from...."

"Galactic Civilization!" Martia exclaimed.

Scarface grinned at them. "Yes," he said. "We call it that, because we

have inhabited at least a dozen solar systems and are still growing.

Let me continue the story...."

Mlargn had chosen a group of children because he knew they could be

trained and conditioned easier. When he returned through the Chronotron

to his own time, the Xlarnan immortals considered the human captives

to be unimaginable, short-lived, soft-skinned bipeds, but amazingly

advanced mammalia from the evolutionary viewpoint. And they could

think, in a primitive fashion. Moreover, they proved to be incredibly

fertile.

Only slightly encouraged, the Xlarnans threw them into a Chronotron

cycle of five hundred thousand years. The resultant race and alternate

time proved to be something for which they were totally unprepared.

Since the continuum between Cause and Effect was a simultaneous

structure in time, there it was, complete from beginning to end--a

superman civilization that encompassed great stretches of the

galaxy. An alien brand of intelligence. Virile resourcefulness and

aggressiveness, far outstripping the sterile civilization of Xlarn.

Astounded and frightened, the Xlarnans sought to trace the beginnings

of this alternate time, through the Chronotron, and throttle the

totally unexpected development at its source. However, this was

foreseen by the civilization which had sprung from the Chronotron--and

there was war. The Xlarnans were eliminated, except for one, who swore

vengeance.

This unsuspected immortal was he who had brought back the ancestors of

the star men from beyond Beginning, from the world where the moon was

young. This was Mlargn, himself.

* * * * *

Although the star men had abandoned the dying solar system of their

origin, it was inevitable that a few of their number should be left

behind--castaways who finally organized themselves, built a citadel of

their own, and sought to build a small star ship in which to escape the

threat of the reaction sphere. But the specialized science that had

developed the hyper-space drive eluded them and they struggled in vain,

while Mlargn besieged them, jealously endeavoring to discover what they

were accomplishing. He applied his warfare so vigorously that one day

only Kimnar was left, with two youngsters. In fact, they were babes.

In desperation, Kimnar gained access to the Chronotron. Hoping to

create another alternate time, he hurled himself and the two children

into further depths of time than he intended.

And Mlargn followed him. Aware of his own immortality and equipped

with controls that could reverse his course in time because they were

interlocked with the Chronotron, he was determined to spend centuries,

if necessary, to find those two advanced children and use them to his

own advantage....

* * * * *

Henry shook his head to clear it. "Just a moment," he said. "I might

extrapolate from all this that you are Kimnar."

"I am," smiled Scarface. "I arrived with you two in the human era, in

Earth's calendar year nineteen hundred forty-four A.D., on June 6th,

to be exact. The country was France. The place--Caen...."

There was a stunned moment of silence. Then Martia's eyes widened. "But

that was--!"

"Yes," said Kimnar, smiling grimly. "The Allied invasion of Normandie.

I landed right in the middle of D-Day."

"What happened?" asked Henry. "I mean--to you?"

"I was injured by shrapnel. That's how I acquired the scar on my face.

I woke up later in a hospital and have been looking for you two ever

since."

"Kimnar," said Henry, "are Martia and I sister and brother?"

Martia's mind leaped out to find the answer in Kimnar's thoughts before

he could speak. "No!" she cried, happily. "We're not!" Henry suddenly

found her in his arms.

"She's right," Kimnar confirmed.

"You two were survivors of Mlargn's attack in those days when Jirahn

was alive--but you were not of the same family."

"Who was Jirahn?"

Kimnar waved a hand toward the great instrument panel. "It was he who

invented that hyper-space transceiver. Or rather, he re-invented it,

remembering much of the science of our kin, the star men. Just before

Mlargn's powerful attack, in which he utilized a deadly radiation

that killed everybody in the citadel, I believe Jirahn succeeded in

contacting the star men. But I could not be certain, as I had been

away from the citadel when the attack came. Upon my return, I found

my friends dead, and Jirahn sat slumped over those controls with the

head gear attached to him. Certain lights were signalling to me from

the board, but I could not decipher them. Moreover, I feared that

Mlargn would find the right teleporter frequency to tie his system in

with ours, and that he might surprise me at any time. So I removed the

bodies, dumping them into the sea, and prepared, generally, to 'abandon

ship.' Just as I was about to leave, I found you two halfway down the

cliffs on a covered terrace that your parents had been in the habit

of using. They had left you there for your naps. It was then that I

conceived the idea of finding the Chronotron and trying to create a new

alternate time based on your descendants."

"But Kimnar," persisted Henry. "What about that transceiver? You worked

it when we first arrived here, and I remember you mentioned something

about 'waiting for results.'"

Kimnar shrugged. "I tried the thing, and to the best of my knowledge I

was transmitting through hyper-space at full power. So far, there has

been no response. I have the receiver wide open."

"Do you mean--it is conceivable that some of the star people might

return for us?"

Kimnar smiled in a puzzling sort of way. "I tossed them the bait," he

said. "I think they'll consider the risk worth while--if they received

my message."

"What risk is there now? I'm quite sure Weston finished Mlargn off."

* * * * *

Kimnar raised his eyes heavenward. "Remember? The reaction sphere could

go any time. Fortunately, most of the harder radiations are expending

themselves convexly, into outer space, and what is shooting towards us

still has many miles to travel. But it's getting very unhealthy around

here. When the sphere blows, it will take the Great Ring with it--the

ring that used to be the moon."

Simultaneously, Henry and Martia thought of something else. The other

passengers, their original companions. What of them--and Weston, with

his gun?

"We can't leave them here to die," said Henry. "What about the

Chronotron? Can't we send them all back?"

Kimnar shook his head. "The Chronotron is not that accurate at such

long range. Only a few people at a time can go through, and they

might land anywhere, from Earth's prehistoric ages to Xlarn's eras of

development ante-dating the generation of an oxygen content atmosphere.

Moreover, Mlargn changed the location of the Chronotron. I have not

been able to find it. That was what I originally went back to look for

when I left you on the beach after that fight with Weston."

"Wait a minute!" cried Martia. "But my moth--I mean, Lady Dewitt and

those others found it!"

Kimnar looked at both of them wonderingly. Briefly, they told him about

the alternate time episode involving New Bretania and Texania, which

Mlargn successfully nipped in the bud.

"I must have been underground somewhere at the time," said Kimnar,

"traveling through various teleporters. Otherwise, had I been on the

surface, I have enough temporal perspective, myself, to have been able

to remember that alternate time experience." He frowned. "If Weston

ever finds the Chronotron--"

"Well, why not?" asked Martia. "You couldn't blame them for going

back--or trying to!"

"I see what he means," said Henry. "If any of them should go back

to the approximate time from which we started and do anything to

circumvent that moon experiment--"

"_What_ moon experiment?" asked Martia.

"I forgot to tell you, I guess. Kimnar knew because he read it in

Uncle Andy's mind. Uncle Andy as Andrew Dearden, is one of the world's

greatest rocket specialists. He was just returning from Africa on that

plane after having supervised all preparations for firing a rocket at

the moon."

"That _is_ amazing," said Martia, "but--oh!" She read the rest in

Henry's mind. The rocket carried the world's first D-C bomb, which

letters represented the word, "de-cohesion." In detonation, the bomb

was supposed to liberate the cohesive forces of the proton. They were

going to observe its effects on the moon.

"I believe," said Henry, "that it produced a sustained reaction in

stable matter, and the moon blew to fragments, thus creating the Great

Ring. The thermal effects plus orbital perturbations of the Earth

destroyed all life on the planet. And I deduce that the free oxygen and

hydrogen in our atmosphere made some kind of critical mixture and went

_foom_! The result was H_{2}O, oceans of it. And so time began again,

biologically speaking, anyway."

"If Andrew Dearden or any of his kind get back there and manage to

abolish the 'D-C' bomb," said Kimnar, "then Xlarn will never have

been, and neither you nor I nor Galactic Civilization, with its myriad

worlds and metropoli and billions of star people and all their science

and culture, shall have ever evolved. And there you have a difficult

question. Is it better for us to relinquish our existence for the sake

of a civilization that might have continued, or to preserve a greater

one that actually exists _now_?"

* * * * *

Before they could bring much concentration to bear upon this weighty

problem, a new situation diverted their attention. Inasmuch as the

three of them were standing by the transparent wall of the citadel and

facing shoreward, they could not help seeing the small industrial city

that suddenly sprang into being there. Again, up on the hill, was a

great black rocket, its nose pointing toward the threatening sky.

But this was not New Bretania. Nor was it Texania. Nor was there the

slightest evidence of any type of conflict or preparations for defense,

except in the design of the rocket, itself.

"That's a different alternate!" said Henry, instantly. "The city is

different--more heavily industrialized. See the steel mills? It's even

futuristic. Those insulator towers and antenna, for some kind of power

transmission--"

"And that rocket is different--more efficient looking," observed

Martia. "It seems to carry armament. You can see the firing cupolas."

"You're both very calm about it," said Kimnar. "Somebody has found the

Chronotron. Come on!"

A moment after they had stepped through the teleporter, leaving the

island citadel deserted, the hyper-space receiver began to react to

signals. Lights flickered rapidly for several minutes. Then a human

voice boomed into the empty dome. It spoke in a strange language,

rapidly, urgently. But there was no operator there to reply....

When Kimnar, Henry and Martia stepped through the teleporter, they

arrived in the circular room they had first visited in the subterranean

world of Xlarn.

"There's somebody down here," said Henry.

"They're in that room with the vision screens," added Martia.

Kimnar frowned. "You're right, and I sense that one of them is Weston.

Let's have a closer look!"

But already, it seemed, detectors had discovered their presence. In

three seconds they heard running footsteps and they saw the tell-tale

progression of light advancing toward them along the curved passageway.

Two men came into view, to be followed by a man on crutches who

shouldered his way in between them.

"Weston!" exclaimed Martia.

"Dr. Edwards!" Henry cried out. Edwards was the man with the gun--the

same gun that Kimnar had used against Mlargn.

The other member of the trio was the Indian Prince, his precious turban

now much disheveled and awry.

"Aha!" cried Weston, grinning and leaning on his crutches with a

derisive air. "So the wanderers have returned!"

* * * * *

The Indian Prince ran forward and kneeled before Henry, wringing his

hands in supplication. In his fat, brown face and his wide, brown eyes

was registered an expression of terror and desperation.

"Henry!" he exclaimed. "Only you can give me the answer--it is all so

mixed up that I cannot understand. Only you can tell me if it's true!"

"If _what_ is true?" asked Kimnar.

"Shut up, Mohammed!" yelled Weston. "Edwards knows what he's doing!

Tell them, Edwards!--before you plug 'em!"

Since Edwards held the gun, he took time to explain. In his eyes was a

wild sort of triumph.

"I don't know where you three have been," he said, "but in your

absence a great deal has happened. Since young Henry, here, has always

exhibited his great intelligence so willingly, perhaps he would

corroborate my own deductions--by doing some fast extrapolating!" He

said this last word through his teeth. There was a smile on his lips,

but not in his dark and wearied eyes.

As he went on rapidly with his story, his three listeners were scanning

his mind for the rest of it, putting the whole picture together even

before he had finished.

When Weston killed Mlargn, he managed to manipulate controls that

finally released all the others from their mental paralysis. He made

Lady Dewitt and the Texans show him the location of the Chronotron, and

under directions from the various scientists at his command a series

of experiments was conducted. Various power settings were utilized,

and test groups volunteered or were assigned to be sent back through

time. Some, they knew, might arrive in a place where conditions would

not be suitable for life. Others might perish in a world populated

by carnivorous monsters, or they might freeze, or drown in shoreless

oceans. But most of them seemed willing to risk it.

It was Uncle Andy's group that produced the alternate time that the

three had witnessed from the citadel. This group had consisted of Andy,

Dr. Bauml, Dr. Singer, Valerie Roagland, Peggy Hollenbeck, and several

other men and women. Pee Bee, it developed, had been in the first

"group," which had consisted only of himself--as he had apparently

been in a suicidal mood and was desirous of giving the dice a roll for

double or nothing.

Andy's group, it appeared, had only been thrown back about a thousand

years, because the "civilization" they founded was small and still

dedicated to the same goals which had been in the minds of the basic

group when they entered the Chronotron. These descendants remembered

their ancestors and carried some of their theories to the point of

physical application.

* * * * *

In the meantime, only Weston, Edwards and the Prince remained below.

The alternate time civilization, which referred to itself as "Little

America," had appropriated the Xlarnan underworld facilities for

itself, and the three observers had found it necessary to conceal

themselves. To their dismay, the "Little Americans" had destroyed the

Chronotron in order to make certain that none of their group would ever

be tempted to snuff them out with a superimposed alternate.

Far from abandoning the idea of returning to the world and time of

their ancestors' origin they had concentrated on time-travel theories

of their own, with the intention of evolving a more accurate method so

that they could be sure of where they were going.

"You said something to me and your Uncle Andy on board the plane before

all this happened," Edwards remarked to Henry. "Something about novae

and super fast light rays being thrown along the Fourth Coordinate.

That must have started them on the road to their present discoveries

and development, because there's a ship out there now that only uses

rockets for take-off and navigational purposes. Once out in deep space

it is supposed to operate on Cosmic energy, or so we have heard. It

will go out faster than light. The idea is that when that happens it

will be rotated out of three dimensional space and be forced to expend

its extra velocity along the Fourth Coordinate, emerging in another

time when it again slows down to the speed of light. But this isn't

all. These scientists have worked out some new kind of mathematics

and seem convinced they have been able to determine the direction and

the rates of acceleration and deceleration necessary to deliver them

into any given era of time, past or future. And their flight equation

calls for the time we came from. Of course, they'll not hit it in the

first attempt, but all subsequent time-jumps will be like vernier

adjustments, focussing them down into the twentieth century--even that

specific part of it they're aiming for."

"You can't let them do it!" exclaimed Kimnar. Weston, Edwards and the

Prince stared at him in mild astonishment.

"I don't know what your objections may be, Scarface," said Edwards,

"but as a matter of fact we _don't_ intend to let them get away with

it!"

Weston grinned sadistically, his gold-capped teeth glistening. "You

see--_we_ are going instead! Of course we'll cop their pilot, and he'll

do what we tell him. And here's another little point. I'm not so sharp

with the science, so Edwards will tell you that, too. Tell them about

Africa, Doc!"

* * * * *

The three listeners tensed. They saw it coming. The "Little Americans"

were well aware of Andy's connection with the D-C bomb. Andy, too, had

been able to deduce, largely from the lack of ocean tides in this world

of Xlarn, that it could have been the bomb that had brought the world

of Xlarn into being by the destruction of the moon. The most sacred

admonishment to his descendants in alternate time had been to find

a way of getting back to the twentieth century and prevent the bomb

from being launched. That single act would enable the original Earth

civilization to continue, and Xlarn would cease to exist.

"It's all a nice, neat package," said Weston, "because don't forget I

worked that French Morocco project, too, and I know how to sabotage

that damned rocket! Then to make the whole story turn out real pretty

with a happy ending, we have Mohammed here to pay off like he said, for

getting him back home!"

The Prince still looked at Henry, his turban almost down over his eyes.

"You have heard!" he cried out. "Tell me, Henry! Can it be done?"

"There's just one little technicality," said Henry. "How do you propose

to capture that Cosmic drive rocket outside?"

Weston grinned again, and Dr. Edwards explained. "Our friends upstairs

never suspected our existence. They probably assumed we got lost

somewhere in the Chronotron. Having had no one to defend themselves

against, they have produced no weapons of any description, with the

exception of those they have installed on the rocket, for use when they

get back to the twentieth century, if necessary, to force the issue

concerning the D-C bomb. So they are quite vulnerable to a surprise

attack. This gun should do the trick easily enough. It is fully loaded."

"What of their superior numbers?" asked Kimnar. But he read the answer

before it was voiced.

"The poor devils were quite aware of the reaction sphere," Edwards

answered. "There isn't much time left, you know. They chose their

pilgrims, and the rest--"

Martia paled. "All dead!" she exclaimed.

Edwards shrugged. "Euthanasia. Tragic, perhaps, but very convenient.

We only have six men to contend with."

"I don't want to appear too forward about all this," said Kimnar,

slipping back into the sarcastic dialect of Scarface, "but we'd like to

ride in that star buggy, ourselves. Maybe you can use another hand in

your surprise attack?"

Henry and Martia looked at him quizzically, then their brows furrowed

in deeper puzzlement as they read the weighty thing that was in his

mind.

"To hell with you," yelled Weston. "I owe you something for that lousy

deal you gave me on the rock. On second thought, maybe a bullet would

be too easy. Maybe you should wait and see the sky blow up. You and the

kids wouldn't want to miss all the pretty fireworks, now would you?"

The Prince sprang into action. Swiftly, he took up a position in front

of Henry, Martia and Kimnar. Trembling, and with arms outspread,

he cried out, "If you leave them, you can leave me, too! Shoot

me--anything! But Henry and his friends are sacred! They go, or I stay!"

Dr. Edwards grimaced, looked at his gun, then at Weston. The latter

glowered at the Prince, menacingly.

Finally, he muttered an oath that made Martia's face turn crimson. And

he added, "What's the difference! We'll take you as excess baggage, but

on condition you'll follow orders. Edwards here is going to be awful

nervous on that trigger, so don't try anything."

* * * * *

The surface world was very warm and the sky was sickeningly bright.

Vegetation drooped, dried up, dead or dying, and the plant stench of

rot was in the degenerating air. In the mind of every sweating human

left on Xlarn was one thought:

_It can happen any second now...._

Driven by the deadly threat of the sky, Weston and Edwards did not

waste time on strategy. They approached the rocket base directly, out

in the open, in the glaring light. The pilot and one other man was

inside. Four others met them, in mild astonishment, but there was very

little time for conversation.

When Weston let them know his intention, and when they looked at Dr.

Edwards' gun, they smiled, resignedly.

"What is life or death to us now?" said the spokesman, a somewhat older

man than the others. "The main consideration is our common purpose.

You, too, want to stop the _bomb_. And if Doctor Edwards here is, as

you say, a prominent authority known to that time, his influence would

be greater than ours. As long as you intend to take Kennedy, the pilot,

our efforts and sacrifices shall not have been in vain. Go--before it

is too late!"

Once at the ladder Weston threw the crutches away and practically

pulled himself up to the airlock with his powerful arms. Edwards

followed close behind with his gun, and then came Martia, Henry and

Kimnar, who gave the Prince a helping hand as he climbed.

The four on the ground watched silently for five minutes.

Then they saw their colleague, Mark Thixton, climb down out of the

rocket. That left Kennedy alone--with those others.

Thixton walked over to his waiting friends. "Seven of them," he said.

"The two youngsters will have to share an acceleration sling together."

After a long moment he added, "Pray God they make it in time!"

The others said nothing. They only hoped Kennedy would take off fast

enough to get through that raving pile in the sky. The radiation

insulation was excellent in that ship, but they still wondered if

escape would be possible.

_It can happen any second now...._

* * * * *

When Martia pulled out of the blackness that she had fallen into during

acceleration, she began to cry. Henry could read the thought in her

mind. Those brave, kind men back there--left to die.

Then came a disturbing thought from Kimnar who lay in the sling above

them: _You realize that we are through the reaction sphere. If they

succeed in their purpose, you and I cease to exist. But what really

matters is Galactic Civilization! That, too, will evaporate and be

non-existent!_

Henry and Martia were too weak to think back at him. But they thought

to themselves. Earth, as they had known it, with its teeming billions

of people and its cities and sciences and cultures.

_And its wars and nationalisms and ideologies and greed and

corruption!_--interposed Kimnar's thought, vehemently.

But its beaches under the blue skies and a real, normal sun, with the

children bathing and laughing, and its theatres and arts, its churches

and universities and--Paris! Think of Paris! If they could stop the

bomb, all that would continue to be--

_I can show you six thousand cities greater than Paris! And if you

consider Earth, then think of solar systems--dozens of worlds greater

than Earth--more advanced, benevolent, civilized, where men cannot lie

and cheat because they know each other's hearts and minds! Weigh all

that against one world!_

_No_--thought Henry, at last. _Consider Earth's own future expansion,

if saved from cataclysm. Think of its own possibilities of reaching for

the stars and also establishing a Galactic Civilization!_

Kimnar did not respond.

Suddenly, Kennedy came out of his straps and yelled. He was looking out

the great vision port, from which the radiation shielding had been

removed. Everybody sat up and stared into outer space.

In the lower part of their field vision was the Great Ring that had

once been the moon, and below it was the glowing reaction sphere that

covered Xlarn. It looked like an incandescent Saturn, with the mighty

star-walls of Infinity rising behind it. But even this tremendous

spectacle was insignificant in its effect when compared with ten other

prominent objects out there.

"Space ships!" shouted Weston. "Where the hell--"

Ten great spheres, with rods at top and bottom and thick rings around

their "equators," as though they were space-flying gyroscopes. They

were converging slowly upon the rocket.

"Shall I tell you what they are?" asked Kimnar enthusiastically. "They

are in the hands of Fate!"

"If you know what they are, don't get corny, Scarface!" roared Weston,

climbing out of his sling and grabbing the gun from Edwards. "Spill it!"

Calmly but swiftly, Kimnar told the story, and he explained the issue

that hung in the balance--Earth's alternate future against this already

existing Galactic Civilization.

"Here and now," he concluded, "Fate can decide. Perhaps it is not in

our own hands, after all."

Dr. Edwards stared at him aghast, the whole explanation of Henry's and

Martia's precociousness striking him at last. Then he looked again at

the approaching spheres.

"Do they know what we represent?" he asked.

"Yes," smiled Kimnar. "I communicated the message to them some time

ago. I thought I was lying to them then, or doing some wishful

thinking, merely to make them come for us--but now it's no longer a

lie. You _can_ stop that moon bomb and strike a new alternate across a

billion years of space and time! But if you do, I and my friends and a

Galactic Civilization will cease to exist!"

All this time, the pilot, Kennedy, had been like a man coming out of

anesthesia. He was a tall, gaunt young fellow with heavy, forward

jutting brows and far seeing eyes. His long chin was way out as he

watched everything and listened, with his wiry right hand lying inertly

beside the simple bank of the ship's main controls.

"Kennedy!" yelled Weston. "What kind of guns are in those blisters?"

The pilot stared at him. "They fire one pound projectiles--nuclear

bombs."

"_That_ is for me! Come on, Edwards! To your station!" Before anyone

could stop him, he was swinging lightly away, from support to support,

under the gravity free condition of free fall.

"Better strap in tight!" called Kennedy, coming to life at last. "If

I'm going to maneuver out here, you're going to feel some Gs!"

"Let's go!" they heard Weston reply, from his blister. And Edwards was

already on his way to the other position.

Grimly, the pilot shifted into emergency flight position and strapped

himself in, while Kimnar and Henry and Martia watched him. They heard

the Indian Prince stuttering through his prayers again.

"Kennedy," said Kimnar, half rising in his sling. "Don't do it!"

"You better stay strapped," replied the other. Even as he spoke, a

great weight pressed upon them and the firmament outside began to

revolve, sweeping Xlarn and the star ships momentarily out of sight.

"Kennedy!" persisted Kimnar, doggedly, in spite of the mounting

pressure "Think this over! One world--Earth--cannot be worth twelve

civilized solar systems! Let me contact those star men for you! You

could continue to live--"

Everybody came close to blacking out as the rocket swept down over

the row of globular ships and shook with recoil from Weston's and

Edward's firing. A horrifying scene of exploding spheres swept by

the observation panels, and Martia screamed in her mixed despair.

Kimnar sweated profusely. Henry tensed his mind, preparing to paralyze

Kennedy. It was an irresistible impulse, not quite tied to logic.

_No!_--came Kimnar's thought to him. _I have decided against that kind

of coercion. There's something bigger out here than we. Call it Fate,

if you will. And that power alone will have to decide! We can only

propose!_

* * * * *

It was in that moment that Fate cut the cord. An eye-searing light

filled the cabin, and Kennedy shrieked--"The reaction sphere!"

The planet once known as Earth burst into a minor nova, blasting its

Great Ring into spiraling shreds and tatters of celestial tinsel. In

the face of that swiftly advancing flame, the star ships that had

survived the rocket's first onslaught flicked safely into hyper-space,

and Kennedy _tried_ to stand enough Gs of acceleration to keep ahead of

it. He barely made it.

But Weston and Edwards did not. At first they were blinded, utterly, by

the blast, unprotected as they were in the blisters. Then, as a very

small fraction of that searing wave licked out at the rocket, the hull

resisted but the blisters fused and exploded. An airlock sealed the gun

compartments off from the rocket's cabin, but the remains of the two

gunners drifted into the turbulent ether.

There was one other decisive effect of the holocaust. Certain delicate

apparatus connected with the collection and storing of Cosmic energy

was also fused and made useless, before it had hardly begun to store up

for the intended work ahead.

"That does it!" panted Kennedy. "We're licked!"

"No we're not," said Kimnar, nodding toward the observation panel.

His tear-flooded eyes were struggling out of the momentarily induced

blindness and he saw that the rocket had turned so that the glare of

the explosion was not visible.

Instead, there was the towering, eternal firmament, and in it had

suddenly materialized one of the star man spheres, glistening brightly

in the light that their eyes were now being spared. Kennedy watched it

helplessly as it approached.

Henry and Martia became aware of minds probing them gingerly and

communing with Kimnar--minds of the star men, who had not struck back

immediately because they had been hoping to rescue some of their own

kind and take them home....

_While a bewildered but grateful man named Kennedy and a wide-eyed

Indian Prince followed Kimnar, Henry and Martia into a scintillating

civilization in far off space and time, a secret rocket experiment was

being concluded in French Morocco. In the nose of the rocket was a D-C

bomb, which was to be detonated on the surface of the moon._

_No one who had entered the Chronotron, at Weston's insistence, had

succeeded in reaching the twentieth century and altering the future by

a hair. But Pee Bee had shot far behind the line, landing somewhere

in the 8th century B.C. No change in original Cause can ever fail to

precipitate an equal degree of change in final Effect. Yet the world

that existed between the 8th century B.C. and the twentieth century

A.D. was not greatly shaken by having a few lines of print changed here

and there in various histories, reference books and encyclopedias. It

seemed that there never had been such a word as billiards. There was an

ancient game known as pool (Egypt.--puul), the origin of which was not

England, but in the glorious imperial days of Ethiopia, when Egypt was

one of its provinces and a famous emperor referred to later by Roman

historians as Pibeus, invented it to amuse his harem of two hundred

wives...._
