Albin laughed. "That's just looking for trouble."

"Maybe it is, but that's my job. Hugo's the designer of the time

machine and you're the operator, but I'm the theoretical man in this

research team. It's my job to look for trouble. So, just in case, I

wrote a brief history of the world from the time the missile exploded

in the Pacific. It tells why ours is the worst possible of futures.

It's in that box."

"What do I do with it--hand it to the guy from the alternate 2089?"

The small fat man exasperatedly hit the side of the time machine with

a well-cushioned palm. "You know better. There won't be any alternate

2089 until you push that red switch on the green instrument panel. The

moment you do, our world, with all its slow slide to extinction, goes

out and its alternate goes on--just like two electric light bulbs on a

push-pull circuit. We and every single one of our artifacts, including

the time machine, disappear. The problem is how to keep that manuscript

from disappearing.

"Well, all you do, if I have this figured right, is shove the metal

box containing the manuscript out into the surrounding temporal medium

a moment before you materialize to do your job. That temporal medium

in which you'll be traveling is something that exists independent of

and autonomous to all possible futures. It's my hunch that something

that's immersed in it will not be altered by a new time sequence."

* * * * *

"Remind him to be careful, Bob," Honek rumbled. "He thinks he's Captain

Blood and this is his big chance to run away to sea and become a

swashbuckling pirate."

Albin grimaced in annoyance. "I _am_ excited by doing something

besides sitting in a safe little corner working out safe little

abstractions for the first time in my life. But I know that this is a

first experiment. Honestly, Hugo, I really have enough intelligence to

recognize that simple fact. I know that if anything unexpected pops up,

anything we didn't foresee, I'm supposed to come scuttling back and ask

for advice."

"I hope you do," Bob Skeat sighed. "I hope you do know that. A

twentieth century poet once wrote something to the effect that the

world will end not with a bang, but a whimper. Well, our world is

ending with a whimper. Try to see that it doesn't end with a bang,

either."

"That I'll promise you," Albin said a trifle disgustedly. "It'll end

with neither a bang _nor_ a whimper. So long, Hugo. So long, Bob."

He twisted around, reaching overhead for the lever which activated the

forces that drove the time machine.

It was strange, Max Alben reflected, that this time travel business,

which knocked unconscious everyone who tried it, only made him feel

slightly dizzy. That was because he was descended from Giovanni Albeni,

he had been told. There must be some complicated scientific explanation

for it, he decided--and that would make it none of his business. Better

forget about it.

All around the time machine, there was a heavy gray murk in which

objects were hinted at rather than stated definitely. It reminded him

of patrolling his beat at the North American Chicken Reservation in a

thick fog.

According to his gauges, he was now in 1976. He cut speed until he hit

the last day of April, then cut speed again, drifting slowly backward

to the eighteenth, the day of the infamous Guided Missile Experiment.

Carefully, carefully, like a man handling a strange bomb made on a

strange planet, he watched the center gauge until the needle came to

rest against the thin etched line that indicated the exactly crucial

moment. Then he pulled the brake and stopped the machine dead.

All he had to do now was materialize in the right spot, flash out and

pull the red switch toward him. Then his well-paid assignment would be

done.

But....

He stopped and scratched his dirt-matted hair. Wasn't there something

he was supposed to do a second before materialization? Yes, that

useless old windbag, Sadha, had given him a last instruction.

He picked up the sealed metal cylinder, walked to the entrance of the

time machine and tossed it into the gray murk. A solid object floating

near the entrance caught his eye. He put his arm out--whew, it was

cold!--and pulled it inside.

A small metal box. Funny. What was it doing out there? Curiously,

he opened it, hoping to find something valuable. Nothing but a few

sheets of paper, Alben noted disappointedly. He began to read them

slowly, very slowly, for the manuscript was full of a lot of long and

complicated words, like a letter from one bookworm scientist to another.

The problems all began with the Guided Missile Experiment of 1976,

he read. There had been a number of such experiments, but it was

the one of 1976 that finally did the damage the biologists had been

warning about. The missile with its deadly warhead exploded in the

Pacific Ocean as planned, the physicists and the military men went

home to study their notes, and the world shivered once more over the

approaching war and tried to forget about it.

But there was fallout, a radioactive rain several hundred miles to

the north, and a small fishing fleet got thoroughly soaked by it.

Fortunately, the radioactivity in the rain was sufficiently low to do

little obvious physical damage: All it did was cause a mutation in the

mumps virus that several of the men in the fleet were incubating at the

time, having caught it from the children of the fishing town, among

whom a minor epidemic was raging.

* * * * *

The fleet returned to its home town, which promptly came down with the

new kind of mumps. Dr. Llewellyn Shapiro, the only physician in town,

was the first man to note that, while the symptoms of this disease were

substantially milder than those of its unmutated parent, practically no

one was immune to it and its effects on human reproductivity were truly

terrible. Most people were completely sterilized by it. The rest were

rendered much less capable of fathering or bearing offspring.

Shapiro's Mumps spread over the entire planet in the next few decades.

It leaped across every quarantine erected; for a long time, it

successfully defied all the vaccines and serums attempted against

it. Then, when a vaccine was finally perfected, humanity discovered

to its dismay that its generative powers had been permanently and

fundamentally impaired.

Something had happened to the germ plasm. A large percentage of

individuals were born sterile, and, of those who were not, one child

was usually the most that could be expected, a two-child parent being

quite rare and a three-child parent almost unknown.

Strict eugenic control was instituted by the Security Council of the

United Nations so that fertile men and women would not be wasted upon

non-fertile mates. Fertility was the most important avenue to social

status, and right after it came successful genetic research.

Genetic research had the very best minds prodded into it; the lesser

ones went into the other sciences. Everyone on Earth was engaged in

some form of scientific research to some extent. Since the population

was now so limited in proportion to the great resources available, all

physical labor had long been done by robots. The government saw to it

that everybody had an ample supply of goods and, in return, asked only

that they experiment without any risk to their own lives--every human

being was now a much-prized, highly guarded rarity.

There were less than a hundred thousand of them, well below the danger

point, it had been estimated, where a species might be wiped out by a

new calamity. Not that another calamity would be needed. Since the end

of the Epidemic, the birth rate had been moving further and further

behind the death rate. In another century....

That was why a desperate and secret attempt to alter the past was being

made. This kind of world was evidently impossible.

Max Alben finished the manuscript and sighed. What a wonderful world!

What a comfortable place to live!

He walked to the rear dials and began the process of materializing at

the crucial moment on April 18, 1976.

_flick!_

* * * * *

It was odd, Mac Albin reflected, that these temporal journeys, which

induced coma in everyone who tried it, only made him feel slightly

dizzy. That was because he was descended from Giovanni Albeni, he

knew. Maybe there was some genetic relationship with his above-average

fertility--might be a good idea to mention the idea to a biologist or

two when he returned. _If_ he returned.

All around the time machine, there was a soupy gray murk in which

objects were hinted at rather than stated definitely. It reminded him

of the problems of landing a helicopter in a thick fog when the robot

butler had not been told to turn on the ground lights.

According to the insulated register, he was now in 1976. He lowered

speed until he registered April, then maneuvered slowly backward

through time to the eighteenth, the day of the infamous Guided Missile

Experiment. Carefully, carefully, like an obstetrician supervising

surgical robots at an unusually difficult birth, he watched the

register until it rolled to rest against the notch that indicated the

exactly crucial moment. Then he pushed a button and froze the machine

where it was.

All he had to do now was materialize in the right spot, flash out and

push the red switch from him. Then his exciting adventure would be over.

But....

He paused and tapped at his sleek chin. He was supposed to do something

a second before materialization. Yes, that nervous theoretician, Bob

Skeat, had given him a last suggestion.

He picked up the small metal box, twisted around to face the opening

of the time machine and dropped it into the gray murk. A solid object

floating near the opening attracted his attention. He shot his arm

out--it was _cold_, as cold as they had figured--and pulled the object

inside.

A sealed metal cylinder. Strange. What was it doing out there?

Anxiously, he opened it, not daring to believe he'd find a document

inside. Yes, that was exactly what it was, he saw excitedly. He began

to read it rapidly, very rapidly, as if it were a newly published paper

on neutrinos. Besides, the manuscript was written with almost painful

simplicity, like a textbook composed by a stuffy pedagogue for the use

of morons.

The problems all began with the Guided Missile Experiment of 1976, he

read. There had been a number of such experiments, but it was the one

of 1976 that finally did the damage the biologists had been warning

about. The missile with its deadly warhead exploded in the Brazilian

jungle through some absolutely unforgivable error in the remote-control

station, the officer in charge of the station was reprimanded and the

men under him court-martialed, and the Brazilian government was paid a

handsome compensation for the damage.

* * * * *

But there had been more damage than anyone knew at the time. A plant

virus, similar to the tobacco mosaic, had mutated under the impact

of radioactivity. Five years later, it burst out of the jungle and

completely wiped out every last rice plant on Earth. Japan and a large

part of Asia became semi-deserts inhabited by a few struggling nomads.

Then the virus adjusted to wheat and corn--and famine howled in every

street of the planet. All attempts by botanists to control the Blight

failed because of the swiftness of its onslaught. And after it had fed,

it hit again at a new plant and another and another.

Most of the world's non-human mammals had been slaughtered for food

long before they could starve to death. Many insects, too, before they

became extinct at the loss of their edible plants, served to assuage

hunger to some small extent.

But the nutritive potential of Earth was steadily diminishing in a

horrifying geometric progression. Recently, it had been observed,

plankton--the tiny organism on which most of the sea's ecology was

based--had started to disappear, and with its diminution, dead fish had

begun to pile up on the beaches.

Mankind had lunged out desperately in all directions in an effort to

survive, but nothing had worked for any length of time. Even the other

planets of the Solar System, which had been reached and explored

at a tremendous cost in remaining resources, had yielded no edible

vegetation. Synthetics had failed to fill the prodigious gap.

In the midst of the sharply increasing hunger, social controls had

pretty much dissolved. Pathetic attempts at rationing still continued,

but black markets became the only markets, and black marketeers the

barons of life. Starvation took the hindmost, and only the most agile

economically lived in comparative comfort. Law and order were had only

by those who could afford to pay for them and children of impoverished

families were sold on the open market for a bit of food.

But the Blight was still adjusting to new plants and the food supply

kept shrinking. In another century....

That was why the planet's powerful individuals had been persuaded to

pool their wealth in a desperate attempt to alter the past. This kind

of world was manifestly impossible.

Mac Albin finished the document and sighed. What a magnificent world!

What an exciting place to live!

He dropped his hand on the side levers and began the process of

materializing at the crucial moment on April 18, 1976.

_flick!_

* * * * *

As the equipment of the remote-control station began to take on a

blurred reality all around him, Max Alben felt a bit of fear at what

he was doing. The technicians, he remembered, the Secretary-General,

even the black market kings, had all warned him not to go ahead with

his instructions if anything unusual turned up. That was an awful lot

of power to disobey: he knew he should return with this new information

and let better minds work on it.

They with their easy lives, what did they know what existence had been

like for such as he? Hunger, always hunger, scrabbling, servility, and

more hunger. Every time things got really tight, you and your wife

looking sideways at your kids and wondering which of them would bring

the best price. Buying security for them, as he was now, at the risk of

his life.

But in this other world, this other 2089, there was a state that took

care of you and that treasured your children. A man like himself, with

_five_ children--why, he'd be a big man, maybe the biggest man on

Earth! And he'd have robots to work for him and lots of food. Above

all, lots and lots of food.

He'd even be a scientist--_everyone_ was a scientist there, weren't

they?--and he'd have a big laboratory all to himself. This other world

had its troubles, but it was a lot nicer place than where he'd come

from. He wouldn't return. He'd go through with it.

The fear left him and, for the first time in his life, Max Alben felt

the sensation of power.

He materialized the time machine around the green instrument panel,

sweating a bit at the sight of the roomful of military figures, despite

the technicians' reassurances that all this would be happening too fast

to be visible. He saw the single red switch pointing upward on the

instrument panel. The switch that controlled the course of the missile.

Now! Now to make a halfway decent world!

Max Alben pulled the little red switch toward him.

_flick!_

* * * * *

As the equipment of the remote-control station began to oscillate into

reality all around him, Mac Albin felt a bit of shame at what he was

doing. He'd promised Bob and Hugo to drop the experiment at any stage

if a new factor showed up. He knew he should go back with this new

information and have all three of them kick it around.

But what would they be able to tell him, they with their blissful

adjustment to their thoroughly blueprinted lives? They, at least, had

been ordered to marry women they could live with; he'd drawn a female

with whom he was completely incompatible in any but a genetic sense.

Genetics! He was tired of genetics and the sanctity of human life,

tired to the tip of his uncalloused fingers, tired to the recesses

of his unused muscles. He was tired of having to undertake a simple

adventure like a thief in the night.

But in this other world, this other 2089, someone like himself would

be a monarch of the black market, a suzerain of chaos, making his own

rules, taking his own women. So what if the weaklings, those unfit to

carry on the race, went to the wall? His kind wouldn't.

He'd formed a pretty good idea of the kind of men who ruled that other

world, from the document in the sealed metal cylinder. The black

marketeers had not even read it. Why, the fools had obviously been

duped by the technicians into permitting the experiment; they had not

grasped the idea that an alternate time track would mean their own

non-existence.

This other world had its troubles, but it was certainly a livelier

place than where he'd come from. It deserved a chance. Yes, that was

how he felt: his world was drowsily moribund; this alternate was

starving but managing to flail away at destiny. It _deserved_ a chance.

Albin decided that he was experiencing renunciation and felt proud.

He materialized the time machine around the green instrument panel,

disregarding the roomful of military figures since he knew they could

not see him. The single red switch pointed downward on the instrument

panel. That was the gimmick that controlled the course of the missile.

Now! Now to make a halfway interesting world!

Mac Albin pushed the little red switch from him.

_flick!_
