RESCUE PARTY 
Who was to blame? For three days Alveron's 
thoughts had come back to that question, and still he 
had found no answer. A creature of a less civilized or a 
less sensitive race would never have let it torture his 
mind, and would have satisfied himself with the assurance 
that no one could be responsible for the working 
of fate. But Alveron and his kind had been lords of the 
Universe since the dawn of history, since that far-distant 
age when the Time Barrier had been folded round 
the cosmos by the unknown powers that lay beyond the 
Beginning. To them had been given all knowledge -- 
and with infinite knowledge went infinite responsibility. 
If there were mistakes and errors in the administration 
of the galaxy, the fault lay on the heads of 
Alveron and his people. And this was no mere mistake: 
it was one of the greatest tragedies in history. 
The crew still knew nothing. Even Rugon, his 
closest friend and the ship's deputy captain, had been 
told only part of the truth. But now the doomed worlds 
lay less than a billion miles ahead. In a few hours, they 
would be landing on the third planet. 
Once again Alveron read the message from Base; 
then with a flick of a tentacle that no human eye 
could have followed, he pressed the 'General Attention' 
button. Throughout the mile-long cylinder that 
was the Galactic Survey Ship S9000, creatures of many 
races laid down their work to listen to the words of 
their captain. 
'I know you have all been wondering,' began Alveron, 
'why we were ordered to abandon our survey 
and to proceed at such an acceleration to this region 
of space. Some of you may realize what this acceleration means. 
Our ship is on its last voyage: the generators 
have already been running for sixty hours at Ultimate 
Overload. We will be very lucky if we return to 
Base under our own power. 
'We are approaching a sun which is about to become 
a Nova. Detonation will occur in seven hours, with an 
uncertainty of one hour, leaving us a maximum of 
only four hours for exploration. There are ten planets 
in the system about to be destroyed-and there is a 
civilization on the third. That fact was discovered only 
a few days ago. It is our tragic mission to contact 
that doomed race and if possible to save some of its 
members. I know that there is little we can do in so 
short a time with this single ship. No other machine 
can possibly reach the system before detonation occurs.' 
There was a long pause during which there could 
have been no sound or movement in the whole of the 
mighty ship as it sped silently toward the worlds ahead. 
Alveron knew what his companions were thinking and 
he tried to answer their unspoken question. 
'You will wonder how such a disaster, the greatest of 
which we have any record, has been allowed to occur. 
On one point I can reassure you. The fault does not 
lie with the Survey. 
'As you know, with our present fleet of under twelve 
thousand ships, it is possible to re-examine each of the 
eight thousand million solar systems in the Galaxy at 
intervals of about a million years. Most worlds change 
very little in so short a time as that. 
'Less than four hundred thousand years ago, the 
survey-ship S5o6o examined the planets of the system 
we are approaching. It found intelligence on none of 
them, though the third planet was teeming with animal 
life and two other worlds had once been inhabited. 
The usual report was submitted and the system is due 
for its next examination in six hundred thousand 
years. 
'It now appears that in the incredibly short period 
since the last survey, intelligent life has appeared in 
the system. The first intimation of this occurred when 
unknown radio signals were detected on the planet 
Kulath in the system X29.35, Y34.76, Z27.93. Bearings 
were taken on them; they were coming from the system 
ahead. 
'Kulath is two hundred light-years from here, so 
those radio waves had been on their way for two centuries. 
Thus for at least that period a civilization' has 
existed on one of these worlds-a civilization that can 
generate electromagnetic waves and all that that implies. 
'An immediate telescopic examination of the system 
was made and it was then found that the sun was in 
the unstable pre-nova stage. Detonation might occur 
at any moment, and indeed might have done so while 
the light waves were on their way to Kulath. 
'There was a slight delay while the supervelocity 
scanners on Kulath II were focused onto the system. 
They showed that the explosion had not yet occurred 
but was only a few hours away. If Kulath had been a 
fraction of a light-year further from this sun, we should 
never have known of its civilization until it had ceased 
to exist. 
'The Administrator of Kulath contacted Sector Base 
immediately, and I was ordered to proceed to the system 
at once. Our object is to save what members we 
can of the doomed race, if indeed there are any left. 
But we have assumed that a civilization possessing 
radio could have protected itself against any rise of 
temperature that may have already occurred. 
'This ship and the two tenders will each explore a 
section of the planet. Commander Torkalee will take 
Number One, Commander Orostron Number Two. 
They will have just under four hours in which to explore 
this world. At the end of that time, they must be 
back in the ship. It will be leaving then, with or without 
them. I will give the two commanders detailed instructions 
in the control room immediately. 
'That is all. We enter atmosphere in two hours.' 
 
On the world once known as Earth the fires were 
dying out: there was nothing left to burn. The great 
forests that had swept across the planet like a tidal 
wave with the passing of the cities were now no more 
than glowing charcoal and the smoke of their funeral 
pyres still stained the sky. But the last hours were still 
to come, for the surface rocks had not yet begun to 
flow. The continents were dimly visible through the 
haze, but their outlines meant nothing to the watchers 
in the approaching ship. The charts they possessed 
were out of date by a dozen Ice Ages and more deluges 
than one. 
The S9000 had driven past Jupiter and seen at once 
that no life could exist in those half-gaseous oceans of 
compressed hydrocarbons, now erupting furiously 
under the sun's abnormal heat. Mars and the outer 
planets they had missed, and Alveron realized that the 
worlds nearer the sun than Earth would be already 
melting. It was more than likely, he thought sadly, 
that the tragedy of this unknown race was already 
finished. Deep in his heart, he thought it might be 
better so. The ship could only have carried a few 
hundred survivors, and the problem of selection had 
been haunting his mind. 
Rugon, Chief of Communications and Deputy Captain, 
came into the control room. For the last hour he 
had been striving to detect radiation from Earth, but 
in vain. 
'We're too late,' he announced gloomily. 'I've monitored 
the whole spectrum and the ether's dead except 
for our own stations and some two-hundred-year-old 
programs from Kulath. Nothing in this system is radiating 
any more.' 
He moved toward the giant vision screen with a 
graceful flowing motion that no mere biped could ever 
hope to imitate. Alveron said nothing; he had been 
expecting this news. 
One entire wall of the control room was taken up 
by the screen, a great black rectangle that gave an impression 
of almost infinite depth. Three of Rugon's 
slender control tentacles, useless for heavy work but 
incredibly swift at all manipulation, flickered over the 
selector dials and the screen lit up with a thousand 
points of light. The star field flowed swiftly past as 
Rugon adjusted the controls, bringing the projector 
to bear upon the sun itself. 
No man of Earth would have recognized the monstrous 
shape that filled the screen. The sun's light was 
white no longer: great violet-blue clouds covered half 
of its surface and from them long streamers of flame 
were erupting into space. At one point an enormous 
prominence had reared itself out of the photosphere, 
far out even into the flickering veils of the corona. It 
was as though a tree of fire had taken root in the surface 
of the sun -- a tree that stood half a million miles 
high and whose branches were rivers of flame sweeping 
through space at hundreds of miles a second. 
'I suppose,' said Rugon presently, 'that you are quite 
satisfied about the astronomers' calculations. After 
all --' 
'Oh, we're perfectly safe,' said Alveron confidently. 
'I've spoken to Kulath Observatory and they have 
been making some additional checks through our own 
instruments. That uncertainty of an hour includes a 
private safety margin which they won't tell me in case 
I feel tempted to stay any longer.' 
He glanced at the instrument board. 
'The pilot should have brought us to the atmosphere 
now. Switch the screen back to the planet, please. Ah, 
there they go!' 
There was a sudden tremor underfoot and a raucous 
clanging of alarms, instantly stilled. Across the vision 
screen two slim projectiles dived toward the looming 
mass of Earth. For a few miles they traveled together, 
then they separated, one vanishing abruptly as it 
entered the shadow of the planet. 
Slowly the huge mother ship, with its thousand 
times greater mass, descended after them into the 
raging storms that already were tearing down the 
deserted cities of Man. 
 
It was night in the hemisphere over which Orostron 
drove his tiny command. Like Torkalee, his mission 
was to photograph and record, and to report progress 
to the mother ship. The little scout had no room for 
specimens or passengers. If contact was made with the 
inhabitants of this world, the S9000 would come at 
once. There would be no time for parleying. If there 
was any trouble the rescue would be by force and the 
explanations could come later. 
The ruined land beneath was bathed with an eerie, 
flickering light, for a great auroral display was raging 
over half the world. But the image on the vision screen 
was independent of external light, and it showed 
clearly a waste of barren rock that seemed never to 
have known any form of life. Presumably this desert 
land must come to an end somewhere. Orostron increased 
his speed to the highest value he dared risk in 
so dense an atmosphere. 
The machine fled on through the storm, and presently 
the desert of rock began to climb toward the sky. 
A great mountain range lay ahead, its peaks lost in the 
smoke-laden clouds. Orostron directed the scanners 
toward the horizon, and on the vision screen the line 
of mountains seemed suddenly very close and menacing. 
He started to climb rapidly. It was difficult to 
imagine a more unpromising land in which to find 
civilization and he wondered if it would be wise to 
change course. He decided against it. Five minutes 
later, he had his reward. 
Miles below lay a decapitated mountain, the whole 
of its summit sheered away by some tremendous feat 
of engineering. Rising out of the rock and straddling 
the artificial plateau was an intricate structure of metal 
girders, supporting masses of machinery. Orostron 
brought his ship to a halt and spiraled down toward 
the mountain. 
The slight Doppler blur had now vanished, and the 
picture on the screen was clear-cut. The latticework 
was supporting some scores of great metal mirrors, 
pointing skyward at an angle of forty-five degrees to 
the horizontal. They were slightly concave, and each 
had some complicated mechanism at its focus. There 
seemed something impressive and purposeful about 
the great array; every mirror was aimed at precisely the 
same spot in the sky -- or beyond. 
Orostron turned to his colleagues. 
'It looks like some kind of observatory to me,' he 
said. 'Have you ever seen anything like it before?' 
Klarten, a multitentacled, tripedal creature from a 
globular cluster at the edge of the Milky Way, had a 
different theory. 
'That's communication equipment. Those reflectors 
are for focusing electromagnetic beams. I've seen the 
same kind of installation on a hundred worlds before. 
It may even be the station that Kulath picked up -- 
though that's rather unlikely, for the beams would be 
very narrow from mirrors that size.' 
'That would explain why Rugon could detect no 
radiation before we landed,' added Hansur II, one of 
the twin beings from the planet Thargon. 
Orostron did not agree at all. 
'If that is a radio station, it must be built for interplanetary 
communication. Look at the way the mirrors 
are pointed. I don't believe that a race which has only 
had radio for two centuries can have crossed space. It 
took my people six thousand years to do it.' 
'We managed it in three, said Hansur II mildly, 
speaking a few seconds ahead of his twin. Before the 
inevitable argument could develop, Klarten began to 
wave his tentacles with excitement. While the others 
had been talking, he had started the automatic monitor. 
'Here it is! Listen!' 
He threw a switch, and the little room was filled 
with a raucous whining sound, continually changing 
in pitch but nevertheless retaining certain characteristics 
that were difficult to define. 
The four explorers listened intently for a minute; 
then Orostron said, 'Surely that can't be any form of 
speech! No creature could produce sounds as quickly 
as that!' 
Hansur I had come to the same conclusion. 'That's 
a television program. Don't you think so, Klarten?' 
The other agreed. 
'Yes, and each of those mirrors seems to be radiating 
a different program. I wonder where they're going? If 
I'm correct, one of the other planets in the system must 
lie along those beams. We can soon check that.' 
Orostron called the S9000 and reported the discovery. 
Both Rugon and Alveron were greatly excited, 
and made a quick check of the astronomical records. 
The result was surprising -- and disappointing. 
None of the other nine planets lay anywhere near the 
line of transmission. The great mirrors appeared to be 
pointing blindly into space. 
There seemed only one conclusion to be drawn, and 
Klarten was the first to voice it. 
'They had interplanetary communication,' he said. 
'But the station must be deserted now, and the transmitters 
no longer controlled. They haven't been 
switched off, and are just pointing where they were 
left.' 
'Well, we'll soon find out,' said Orostron. 'I'm going 
to land.' 
He brought the machine slowly down to the level of 
the great metal mirrors, and past them until it came 
to rest on the mountain rock. A hundred yards away, 
a white stone building crouched beneath the maze of 
steel girders. It was windowless, but there were several 
doors in the wall facing them. 
Orostron watched his companions climb into their 
protective suits and wished he could follow. But someone 
had to stay in the machine to keep in touch with 
the mother ship. Those were Alveron's instructions 
and they were very wise. One never knew what would 
happen on a world that was being explored for the 
first time, especially under conditions such as these. 
Very cautiously, the three explorers stepped out of 
the airlock and adjusted the antigravity field of their 
suits. Then, each with the mode of locomotion peculiar 
to his race, the little party went toward the building, 
the Hansur twins leading and Klarten following close 
behind. His gravity control was apparently giving 
trouble, for he suddenly fell to the ground, rather to 
the amusement of his colleagues. Orostron saw them 
pause for a moment at the nearest door -- then it 
opened slowly and they disappeared from sight. 
So Orostron waited, with what patience he could, 
while the storm rose around him and the light of the 
aurora grew even brighter in the sky. At the agreed 
times he called the mother ship and received brief 
acknowledgments from Rugon. He wondered how 
Torkalee was faring, halfway round the planet, but he 
could not contact him through the crash and thunder 
of solar interference. 
It did not take Klarten and the Hansurs long to discover 
that their theories were largely correct. The 
building was a radio station, and it was utterly deserted. 
It consisted of one tremendous room with a few 
small offices leading from it. In the main chamber, row 
after row of electrical equipment stretched into the 
distance; lights flickered and winked on hundreds of 
control panels, and a dull glow came from the elements 
in a great avenue of vacuum tubes. 
But Klarten was not impressed. The first radio set 
his race had built was now fossilized in strata a 
thousand million years old. Man, who had possessed 
electrical machines for only a few centuries, could not 
compete with those who had known them for half the 
lifetime of the Earth. 
Nevertheless, the party kept their recorders running 
as they explored the building. There was still one 
problem to be solved. The deserted station was broadcasting 
programs, but where were they coming from? 
The central switchboard had been quickly located. 
It was designed to handle scores of programs simultaneously, 
but the source of those programs was lost in 
a maze of cables that vanished underground. Back in 
the S9000, Rugon was trying to analyze the broadcasts 
and perhaps his researches would reveal their origin. 
It was impossible to trace cables that might lead across 
continents. 
The party wasted little time at the deserted station. 
There was nothing they could learn from it, and they 
were seeking life rather than scientific information. A 
few minutes later the little ship rose swiftly from the 
plateau and headed toward the plains that must lie 
beyond the mountains. Less than three hours were 
still left to them. 
As the array of enigmatic mirrors dropped out of 
sight, Orostron was struck by a sudden thought. Was it 
imagination, or had they all moved through a small 
angle while he had been waiting, as if they were still 
compensating for the rotation of the Earth? He could 
not be sure, and he dismissed the matter as unimportant. 
It would only mean that the directing mechanism 
was still working, after a fashion. 
They discovered the city fifteen minutes later. It was 
a great, sprawling metropolis, built around a river that 
had disappeared leaving an ugly scar winding its way 
among the great buildings and beneath bridges that 
looked very incongruous now. 
Even from the air, the city looked deserted. But 
only two and a half hours were left -- there was no time 
for further exploration. Orostron made his decision, 
and landed near the largest structure he could see. It 
seemed reasonable to suppose that some creatures 
would have sought shelter in the strongest buildings, 
where they would be safe until the very, end. 
The deepest caves -- the heart of the planet itself -- 
would give no protection when the final cataclysm 
came. Even if this race had reached the outer planets, 
its doom would only be delayed by the few hours it 
would take for the ravening wavefronts to cross the 
Solar System. 
Orostron could not know that the city had been 
deserted not for a few days or weeks, but for over a 
century. For the culture of cities, which had outlasted 
so many civilizations had been doomed at last when the 
helicopter brought universal transportation, Within a 
few generations the great masses of mankind, knowing 
that they could reach any part of the globe in a matter 
of hours, had gone back to the fields and forests for 
which they had always longed. The new civilization 
had machines and resources of which earlier ages had 
never dreamed, but it was essentially rural and no 
longer bound to the steel and concrete warrens that 
had dominated the centuries before. Such cities as still 
remained were specialized centers of research administration 
or entertainment; the others had been 
allowed to decay, where it was too much trouble to 
destroy them. The dozen or so greatest of all cities, and 
the ancient university towns, had scarcely changed 
and would have lasted for many generations to come. 
But the cities that had been founded on steam and 
iron and surface transportation had passed with the 
industries that had nourished them. 
And so while Orostron waited in the tender, his colleagues 
raced through endless empty corridors and 
deserted halls, taking innumerable photographs but 
learning nothing of the creatures who had used these 
buildings. There were libraries, meeting places, council 
rooms, thousands of offices -- all were empty and 
deep with dust. If they had not seen the radio station 
on its mountain eyrie, the explorers could well have 
believed that this world had known no life for centuries. 
 
Through the long minutes of waiting, Orostron 
tried to imagine where this race could have vanished. 
Perhaps they had killed themselves knowing that escape 
was impossible; perhaps they had built great 
shelters in the bowels of the planet, and even now 
were cowering in their millions beneath his feet, waiting 
for the end. He began to fear that he would never 
know. 
It was almost a relief when at last he had to give the 
order for the return. Soon he would know if Torkalee's 
party had been more fortunate. And he was anxious 
to get back to the mother ship, for as the minutes 
passed the suspense had become more and more acute. 
There had always been the thought in his mind: 
What if .the astronomers of Kulath had made a mistake? 
He would begin to feel happy when the walls 
of the S9000 were around him. He would be happier 
still when they were out in space and this ominous sun 
was shrinking far astern. 
As soon as his colleagues had entered the airlock, 
Orostron hurled his tiny machine into the sky and set 
the controls to home on the S9000. Then he turned 
to his friends. 
'Well, what have you found?' he asked. 
Klarten produced a large roll of canvas and spread 
it out on the floor. 
'This is what they were like,' he said quietly. 'Bipeds, 
with only two arms. They seem to have managed 
well, in spite of that handicap. Only two eyes as well, 
unless there are others in the back. We were lucky to 
find this; it's about the only thing they left behind.' 
The ancient oil painting stared stonily back at the 
three creatures regarding it so intently. By the irony 
of fate, its complete worthlessness had saved it from 
oblivion. When the city had been evacuated, no one 
had bothered to move Alderman John Richards, 19o9-1974. 
For a century and a half he had been gathering 
dust while far away from the old cities the new civilization 
had been rising to heights no earlier culture had 
ever known. 
'That was almost all we found,' said Klarten. 'The 
city must have been deserted for years. I'm afraid our 
expedition has been a failure. If there are any living 
beings on this world, they've hidden themselves too 
well for us to find them.' 
His commander was forced to agree. 
'It was an almost impossible task,' he said. 'If we'd 
had weeks instead of hours we might have succeeded. 
for all we know, they may even have built shelters 
under the sea. No one seems to have thought of that.' 
He glanced quickly at the indicators and corrected 
the course. 
'We'll be there in five minutes. Alveron seems to be 
moving rather quickly. I wonder if Torkalee has found 
anything.' 
The S9000 was hanging a few miles above the seaboard 
of a blazing continent when Orostron homed 
upon it. The danger line was thirty minutes away and 
there was no time to lose. Skilfully, he maneuvered the 
little ship into its launching tube and the party stepped 
out of the airlock. 
There was a small crowd waiting for them. That was 
to be expected, but Orostron could see at once that 
something more than curiosity had brought his friends 
here. Even before a word was spoken, he knew that 
something was wrong. 
'Torkalee hasn't returned. He's lost his party and 
we're going to the rescue. Come along to the control 
room at once.' 
 
From the beginning, Torkalee had been luckier 
than Orostron. He had followed the zone of twilight, 
keeping away from the intolerable glare of the sun, 
until he came to the shores of an inland sea. It was a 
very recent sea, one of the latest of Man's works, for the 
land it covered had been desert less than a century before. 
In a few hours it would be desert again, for the 
water was boiling and clouds of steam were rising to 
the skies. But they could not veil the loveliness of the 
great white city that overlooked the tideless sea. 
Flying machines were still parked neatly round the 
square in which Torkalee landed. They were disappointingly 
primitive, though beautifully finished, 
and depended on rotating airfoils for. support. Nowhere 
was there any sign of life, but the place gave the 
impression that its inhabitants were not very far away. 
Lights were still shining from some of the windows. 
Torkalee's three companions lost no time in leaving 
the machine. Leader of the party, by seniority of rank 
and race was T'sinadree, who like Alveron himself had 
been born on one of the ancient planets of the Central 
Suns. Next came Alarkane, from a race which was one 
of the youngest in the Universe and took a perverse 
pride in the fact. Last came one of the strange beings 
from the system of Palador. It was nameless, like all 
its kind, for it possessed no identity of its own, being 
merely a mobile but still dependent cell in the consciousness 
of its race. Though it and its fellows had 
long been scattered over the galaxy in the exploration 
of countless worlds, some unknown link still bound 
them together as inexorably as the living cells in a 
human body. 
When a creature of Palador spoke, the pronoun 
it used was always 'We.' There was not, nor could there 
ever be, any first person singular in the language of 
Palador. 
The great doors of the splendid building baffled 
the explorers, though any human child would have 
known their secret. T'sinadree wasted no time on them 
but called Torkalee on his personal transmitter. Then 
the three hurried aside while their commander 
maneuvered his machine into the best position. There 
was a brief burst of intolerable flame; the massive steelwork 
flickered once at the edge of the visible spectrum 
and was gone. The stones were still glowing when the 
eager party hurried into the building, the beams of 
their light projectors fanning before them. 
The torches were not needed. Before them lay a 
great hall, glowing with light from lines of tubes along 
the ceiling. On either side, the hall opened out into 
long corridors, while straight ahead a massive stairway 
swept majestically toward the upper floors. 
For a moment T'sinadree hesitated. Then, since one 
way was as good as another, he led his companions 
down the first corridor. 
The feeling that life was near had now become very 
strong. At any moment, it seemed, they might be confronted 
by the creatures of this world. If they showed 
hostility -- and they could scarcely be blamed if they 
did -- the paralyzers would be used at once. 
The tension was very great as the party entered the 
first room, and only relaxed when they saw that it held 
nothing but machines -- row after row of them, now 
stilled and silent. Lining the enormous room were 
thousands of metal filing cabinets, forming a continuous 
wall as far as the eye could reach. And that was all; 
there was no furniture, nothing but the cabinets and 
the mysterious machines. 
Alarkane, always the quickest of the three, was already 
examining the cabinets. Each held many 
thousand sheets of tough, thin material, perforated 
with innumerable holes and slots. The Paladorian appropriated 
one of the cards and Alarkane recorded the 
scene together with some close-ups of the machines. 
Then they left. The great room, which had been one 
of the marvels of the world, meant nothing to them. 
No living eye would ever again see that wonderful 
battery of almost human Hollerith analyzers and the 
five thousand million punched cards holding all that 
could be recorded of each man, woman and child on 
the planet. 
It was clear that this building had been used very 
recently: With growing excitement, the explorers 
hurried on to the next room. This they found to be 
an enormous library, for millions of books lay all 
around them on miles and miles of shelving. Here, 
though the explorers could not know it, were the 
records of all the laws that Man had ever passed, and 
all the speeches that had ever been made in his council 
chambers. 
T'sinadree was deciding his plan of action, when 
Alarkane drew his attention to one of the racks a 
hundred yards away. It was half empty, unlike all the 
others. Around it books lay in a tumbled heap on the 
floor, as if knocked down by someone in frantic haste. 
The signs were unmistakable. Not long ago, other 
creatures had been this way. Faint wheel marks were 
clearly visible on the floor to the acute sense of 
Alarkane, though the others could see nothing. 
Alarkane could even detect footprints, but knowing 
nothing of the creatures that had formed them he 
could not say which way they led. 
The sense of nearness was stronger than ever now, 
but it was nearness in time, not in space. Alarkane 
voiced the thoughts of the party. 
'Those books must have been valuable, and someone 
has come to rescue them -- rather as an afterthought, 
I should say. That means there must be a 
place of refuge, possibly not very far away. Perhaps we 
may be able to find some other clues that will lead us 
to it.' 
T'sinadree agreed; the Paladorian wasn't enthusiastic. 
'That may be so,' it said. 'but the refuge may be anywhere 
on the planet, and we have just two hours left. 
Let us waste no more time if we hope to rescue these 
people.' 
The party hurried forward once more, pausing only 
to collect a few books that might be useful to the 
scientists at Base -- though it was doubtful if they could 
ever be translated. They soon found that the great 
building was composed largely of small rooms, all 
showing signs of recent occupation. Most of them were 
in a neat and tidy condition, but one or two were very 
much the reverse. The explorers were particularly 
puzzled by one room -- clearly an office of some kind -- 
that appeared to have been completely wrecked. The 
floor was littered with papers, the furniture had been 
smashed, and smoke was pouring through the broken 
windows from the fires outside. 
T'sinadree was rather alarmed. 
'Surely no dangerous animal could have got into a 
place like this!' he exclaimed, fingering his paralyzer 
nervously. 
Alarkane did not answer. He began to make that 
annoying sound which his race called 'laughter.' It was 
several minutes before he would explain what had 
amused him. 
'I don't think any animal has done it,' he said. 'In 
fact, the explanation is very simple. Suppose you had 
been working all your life in this room, dealing with 
endless papers, year after year. And suddenly, you are 
told that you will never see it again, that your work is 
finished, and that you can leave it forever. More than 
that -- no one will come after you. Everything is 
finished. How would you make your exit, T'sinadree?' 
The other thought for a moment. 
'Well, I suppose I'd just tidy things up and leave. 
That's what seems to have happened in all the other 
rooms.' 
Alarkane laughed again. 
'I'm quite sure you would. But some individuals 
have a different psychology. I think I should have liked 
the creature that used this room.' 
He did not explain himself further, and his two colleagues 
puzzled over his words for quite a while before 
they gave it up. 
It came as something of a shock when Torkalee gave 
the order to return. They had gathered a great deal of 
information, but had found no clue that might lead 
them to the missing inhabitants of this world. That 
problem was as baffling as ever, and now it seemed 
that it would never be solved. There were only forty 
minutes left before the S9000 would be departing. 
They were halfway back to the tender when they 
saw the semicircular passage leading down into the 
depths of the building.. Its architectural style was quite 
different from that used elsewhere, and the gently 
sloping floor was an irresistible attraction to creatures 
whose many legs had grown weary of the marble staircases 
which only bipeds could have built in such profusion. 
T'sinadree had been the worst sufferer, for he 
normally employed twelve legs and could use twenty 
when he was in a hurry, though no one had ever seen 
him perform this feat. 
The party stopped dead and looked down the passageway 
with a single thought. A tunnel, leading 
down into the depths of Earth! At its end, they might 
yet find the people of this world and rescue some of 
them from their fate. For there was still time to call 
the mother ship if the need arose. 
T'sinadree signaled to his commander and Torkalee 
brought the little machine immediately overhead. 
There might not be time for the party to retrace its 
footsteps through the maze of passages, so meticulously 
recorded in the Paladorian mind that there was no 
possibility of going astray. If speed was necessary, 
Torkalee could blast his way through the dozen floors 
above their head. In any case, it should not take long 
to find what lay at the end of the passage. 
It took only thirty seconds. The tunnel ended quite 
abruptly in a very curious cylindrical room with 
magnificently padded seats along the walls. There was 
no way out save that by which they had come and it 
was several seconds before the purpose of the chamber 
dawned on Alarkane's mind. It was a pity, he thought, 
that they would never have time to use this. The 
thought was suddenly interrupted by a cry from 
T'sinadree. Alarkane wheeled around, and saw that 
the entrance had closed silently behind them. 
Even in that first moment of panic, Alarkane found 
himself thinking with some admiration: Whoever 
they were they knew how to build automatic 
machinery! 
The Paladorian was the first to speak. It waved one 
of its tentacles toward the seats. 
'We think it would be best to be seated,' it said. 
The multiplex mind of Palador had already analyzed 
the situation and knew what was coming. 
They did not have long to wait before a low-pitched 
hum came from a grill overhead, and for the very last 
time in history a human, even if lifeless, voice was 
heard on Earth. The words were meaningless, though 
the trapped explorers could guess their message clearly 
enough. 
'Choose your stations, please, and be seated.' 
Simultaneously, a wall panel at one end of the compartment 
glowed with light. On it was a simple map, 
consisting of a series of a dozen circles connected by a 
line. Each of the circles had writing alongside it, and 
beside the writing were two buttons of different colors. 
Alarkane looked questioningly at his leader. 
'Don't touch them,' said T'sinadree. 'If we leave the 
controls alone, the doors may open again.' 
He was wrong. The engineers who had designed the 
automatic subway had assumed that anyone who 
entered it would naturally wish to go somewhere. If 
they selected no intermediate station, their destination 
could only be the end of the line. 
There was another pause while the relays and thyratrons 
waited for their orders. In those thirty seconds, if 
they had known what to do, the party could have 
opened the doors and left the subway. But they did not 
know, and the machines geared to a human psychology 
acted for them. 
The surge of acceleration was not very great; the 
lavish upholstery was a luxury, not a necessity. Only an 
almost imperceptible vibration told of the speed at 
which they were travelling through the bowels of the 
earth, on a journey the duration of which they could 
not even guess. And in thirty minutes, the S9000 would 
be leaving the Solar System. 
There was a long silence in the speeding machine. 
T'sinadree and Alarkane were thinking rapidly. So 
was the Paladorian, though in a different fashion. The 
conception of personal death was meaningless to it, 
for the destruction of a single unit meant no more to 
the group mind than the loss of a nail-paring to a man. 
But it could, though with great difficulty, appreciate 
the plight of individual intelligences such as Alarkane 
and T'sinadree, and it was anxious to help them if it 
could. 
Alarkane had managed to contact Torkalee with his 
personal transmitter, though the signal was very weak 
and seemed to be fading quickly. Rapidly he explained 
the situation, and almost at once the signals became 
clearer. Torkalee was following the path of the 
machine, flying above the ground under which they 
were speeding to their unknown destination. That was 
the first indication they had of the fact that they were 
traveling at nearly a thousand miles an hour, and very 
soon after that Torkalee was able to give the still more 
disturbing news that they were rapidly approaching 
the sea. While they were beneath the land. there was a 
hope, though a slender one, that they might stop the 
machine and escape. But under the ocean -- not all the 
brains and the machinery in the great mother ship 
could save them. No one could have devised a more 
perfect trap. 
T'sinadree had been examining the wall map with 
great attention. Its meaning was obvious, and along the 
line connecting the circles a tiny spot of light was 
crawling. It was already halfway to the first of the 
stations marked. 
'I'm going to press one of those buttons,' said T'sinadree 
at last. 'It won't do any harm, and we may learn 
something.' 
'I agree. Which will you try first?' 
'There are only two kinds, and it won't matter if we 
try the wrong one first. I suppose one is to start the 
machine and the other is to stop it.' 
Alarkane was not very hopeful. 
'It started without any button pressing,' he said. 'I 
think it's completely automatic and we can't control 
it from here at all.' 
T'sinadree could not agree. 
'These buttons are clearly associated with the 
stations, and there's no point in having them unless you 
can use them to stop yourself. The only question is, 
which is the right one?' 
His analysis was perfectly correct. The machine 
could be stopped at any intermediate station. They 
had only been on their way ten minutes, and if they 
could leave now, no harm would have been done. It 
was just bad luck that T'sinadree's first choice was the 
wrong button. 
The little light on the map crawled slowly through 
the illuminated circle without checking its speed. And 
at the same time Torkalee called from the ship overhead. 
'You have just passed underneath a city and are 
heading out to sea. There cannot be another stop for 
nearly a thousand miles.' 
 
Alveron had given up all hope of finding life on this 
world. The S9000 had roamed over half the planet, 
never staying long in one place, descending ever and 
again in an effort to attract attention. There had been 
no response; Earth seemed utterly dead. If any of its 
inhabitants were still alive, thought Alveron, they must 
have hidden themselves in its depths where no help 
could reach them, though their doom would be nonetheless 
certain. 
Rugon brought news of the disaster. The great ship 
ceased its fruitless searching and fled back through the 
storm to the ocean above which Torkalee's little tender 
was still following the track of the buried machine. 
The scene was truly terrifying. Not since the days 
when Earth was born had there been such seas as this. 
Mountains of water were racing before the storm 
which had now reached velocities of many hundred 
miles an hour. Even at this distance from the mainland 
the air was full of flying debris - trees, fragments 
of houses, sheets of metal, anything that had not been 
anchored to the ground. No airborne machine could 
have lived for a moment in such a gale. And ever and 
again even the roar of the wind was drowned as the 
vast water-mountains met head-on with a crash that 
seemed to shake the sky. 
Fortunately, there had been no serious earthquakes 
yet. Far beneath the bed of the ocean the wonderful 
piece of engineering which had been the World President's 
private vacuum-subway was still working perfectly, 
unaffected by the tumult and destruction above. 
It would continue to work until the last minute of the 
Earth's existence, which, if the astronomers were right, 
was not much more than fifteen minutes away -- though 
precisely how much more Alveron would have given 
a great deal to know. It would be nearly an hour before 
the trapped party could reach land and even the 
slightest hope of rescue. 
Alveron's instructions had been precise, though 
even without them he would never have dreamed of 
taking any risks with the great machine that had been 
entrusted to his care. Had he been human, the decision 
to abandon the trapped members of his crew would 
have been desperately hard to make. But he came of a 
race far more sensitive than Man, a race that so loved 
the things of the spirit that long ago, and with infinite 
reluctance, it had taken over control of the Universe 
since only thus could it be sure that justice was being 
done. Alveron would need all his superhuman gifts to 
carry him through the next few hours. 
Meanwhile, a mile below the bed of the ocean, Alarkane 
and T'sinadree were very busy indeed with their 
private communicators. Fifteen minutes is not a long 
time in which to wind up the affairs of a lifetime. It 
is indeed, scarcely long enough to dictate more than a 
few of those farewell messages which at such moments 
are so much more important than all other matters. 
All the while the Paladorian had remained silent 
and motionless, saying not a word. The other two, resigned 
to their fate and engrossed in their personal 
affairs, had given it no thought. They were startled 
when suddenly it began to address them in its 
peculiarly passionless voice. 
'We perceive that you are making certain arrangements 
concerning your anticipated destruction. That 
will probably be unnecessary. Captain Alveron hopes 
to rescue us if we can stop this machine when we reach 
land again.' 
Both T'sinadree and Alarkane were too surprised 
to say anything for a moment. Then the latter gasped, 
'How do you know?' 
It was a foolish question, for he remembered at once 
that there were several Paladorians -- if one could use 
the phrase -- in the S9000, and consequently their companion 
knew everything that was happening in the 
mother ship. So he did not wait for an answer but continued, 
'Alveron can't do that! He daren't take such 
a risk!' 
'There will be no risk,' said the Paladorian. 'We 
have told him what to do. It is really very simple.' 
Alarkane and T'sinadree looked at their companion 
with something approaching awe, realizing now what 
must have happened. In moments of crisis, the single 
units comprising the Paladorian mind could link together 
in an organization no less close than that of any 
physical brain. At such moments they formed an 
intellect more powerful than any other in the Universe. 
All ordinary problems could be solved by a few 
hundred or thousand units. Very rarely, millions would 
be needed, and on two historic occasions the billions of 
cells of the entire Paladorian consciousness had been 
welded together to deal with emergencies that threatened 
the race. The mind of Palador was one of the 
greatest mental resources of the Universe; its .full 
force was seldom required, but the knowledge that 
it was available was supremely comforting to other 
races. Alarkane wondered how many cells had coordinated 
to deal with this particular emergency. He 
also wondered how so trivial an incident had ever come 
to its attention. 
To that question he was never to know the answer, 
though he might have guessed it had he known that the 
chillingly remote Paladorian mind possessed an almost 
human streak of vanity. Long ago, Alarkane had 
written a book trying to prove that eventually all intelligent 
races would sacrifice individual consciousness 
and that one day only group-minds would remain in 
the Universe. Palador, he had said, was the first of 
those ultimate intellects, and the vast, dispersed mind 
had not been displeased. 
They had no time to ask any further questions 
before Alveron himself began to speak through their 
communicators. 
'Alveron calling! We're staying on this planet until 
the detonation waves reach it, so we may be able to 
rescue you. You're heading toward a city on the coast 
which you'll reach in forty minutes at your present 
speed. If you cannot stop yourselves then, we're going 
to blast the tunnel behind and ahead of you to cut off 
your power. Then we'll sink a shaft to get you out -- the 
chief engineer says he can do it in five minutes with 
the main projectors. So you should be safe within an 
hour, unless the sun blows up before.' 
'And if that happens, you'll be destroyed as well! 
You mustn't take such a risk!' 
'Don't let that worry you; we're perfectly safe. When 
the sun detonates, the explosion wave will take several 
minutes to rise to its maximum. But apart from that, 
we're on the night side of the planet, behind an eightthousand-mile 
screen of rock. When the first warning 
of the explosion comes, we will accelerate out of the 
Solar System, keeping in the shadow of the planet. 
Under our maximum drive, we will reach the velocity 
of light before leaving the cone of shadow, and the sun 
cannot harm us then.' 
T'sinadree was still afraid to hope. Another objection 
came at once into his mind. 
'Yes, but how will you get any warning, here on the 
night side of the planet?' 
'Very easily,' replied Alveron. 'This world has a 
moon which is now visible from this hemisphere. We 
have telescopes trained on it. If it shows any sudden 
increase in brilliance, our main drive goes on automatically 
and we'll be thrown out of the system.' 
The logic was flawless. Alveron, cautious as ever, was 
taking no chances. It would be many minutes before 
the eight-thousand-mile shield of rock and metal could 
be destroyed by the fires of the exploding sun. In that 
time, the S9000 could have reached the safety of the 
velocity of light. 
Alarkane pressed the second button when they were 
still several miles from the coast. He did not expect 
anything to happen then, assuming that the machine 
could not stop between stations. It seemed too good to 
be true when, a few minutes later, the machine's slight 
vibration died away and they came to a halt. 
The doors slid silently apart. Even before they were 
fully open, the three had left the compartment. They 
were taking no more chances. Before them a long 
tunnel stretched into the distance, rising slowly out 
of sight. They were starting along it when suddenly 
Alveron's voice called from the communicators. 
'Stay where you are! We're going to blast!' 
The ground shuddered once, and far ahead there 
came the rumble of falling rock. Again the earth shook 
 -- and a hundred yards ahead the passageway vanished 
abruptly. A tremendous vertical shaft had been cut 
clean through it. 
The party hurried forward again until they came to 
the end of the corridor and stood waiting on its lip. 
The shaft in which it ended was a full thousand feet 
across and descended into the earth as far as the torches 
could throw their beams. Overhead, the storm clouds 
fled beneath a moon that no man would have recognized, 
so luridly brilliant was its disk. And, most 
glorious of all sights, the S9000 floated high above, the 
great projectors that had drilled this enormous pit 
still glowing cherry red. 
A dark shape detached itself from the mother ship 
and dropped swiftly toward the ground. Torkalee was 
returning to collect his friends. A little later, Alveron 
greeted them in the control room. He waved to the 
great vision screen and said quietly, 'See, we were 
barely in time.' 
The continent below them was slowly settling 
beneath the mile-high waves that were attacking its 
coasts. The last that anyone was ever to see of Earth 
was a great plain, bathed with the silver light of the 
abnormally brilliant moon. Across its face the waters 
were pouring in a glittering flood toward a distant 
range of mountains. The sea had won its final victory 
but its triumph would be short-lived for soon sea and 
land would be no more. Even as the silent party in the 
control room watched the destruction below, the infinitely 
greater catastrophe to which this was only the 
prelude came swiftly upon them. 
It was as though dawn had broken suddenly over 
this moonlit landscape. But it was not dawn: it was 
only the moon, shining with the brilliance of a second 
sun. For perhaps thirty seconds that awesome, unnatural 
light burnt fiercely on the doomed land 
beneath. Then there came a sudden flashing of indicator 
ights across the control board. The main drive 
was on. For a second Alveron glanced at the indicators 
and checked their information. When he looked again 
at the screen, Earth was gone. 
The magnificent, desperately overstrained generators 
quietly died when the S9000 was passing the orbit 
of Persephone. It did not matter, the sun could never 
harm them now, and although the ship was speeding 
helplessly out into the lonely night of interstellar space, 
it would only be a matter of days before rescue came. 
There was irony in that. A day ago, they had been 
the rescuers, going to the aid of a race that now no 
longer existed. Not for the first time Alveron wondered 
about the world that had just perished. He tried, in 
vain, to picture it as it had been in its glory, the streets 
of its cities thronged with life. Primitive though its 
people had been, they might have offered much to the 
Universe. If only they could have made contact! Regret 
was useless; long before their coming, the people 
of this world must have buried themselves in its iron 
heart. And now they and their civilization would remain 
a mystery for the rest of time. 
Alveron was glad when his thoughts were interrupted 
by Rugon's entrance. The chief of communications 
had been very busy ever since the take-off, 
trying to analyze the programs radiated by the transmitter 
Orostron had discovered. The problem was not 
a difficult one, but it demanded the construction of 
special equipment, and that had taken time. 
'Well, what have you found?' asked Alveron. 
'Quite a lot,' replied his friend. 'There's something 
mysterious here, and I don't understand it. 
'It didn't take long to find how the vision transmissions 
were built up, and we've been able to convert 
them to suit our own equipment. It seems that there 
were cameras all over the planet, surveying points of 
interest. Some of them were apparently in cities, on 
the tops of very high buildings. The cameras were 
rotating continuously to give panoramic views. In the 
programs we've recorded there are about twenty 
different scenes. 
'In addition, there are a number of transmissions of 
a different kind, neither sound nor vision. They seem 
to be purely scientific -- possibly instrument readings 
or something of that sort. All these programs were 
going out simultaneously on different frequency 
bands. 
'Now there must be a reason for all this. Orostron 
still thinks that the station simply wasn't switched off 
when it was deserted. But these aren't the sort of programs 
such a station would normally radiate at all. It 
was certainly used for interplanetary relaying -- Klarten was 
quite right there. So these people must have 
crossed space, since none of the other planets had any 
life at the time of the last survey. Don't you agree?' 
Alveron was following intently. 
'Yes, that seems reasonable enough. But it's also 
certain that the beam was pointing to none of the other 
planets. I checked that myself.' 
'I know,' said Rugon. 'What I want to discover is 
why a giant interplanetary relay station is busily transmitting 
pictures of a world about to be destroyed -- 
pictures that would be of immense interest to scientists 
and astronomers. Someone had gone to a lot of trouble 
to arrange all those panoramic cameras. I am convinced 
that those beams were going somewhere.' 
Alveron started up. 
'Do you imagine that there might be an outer 
planet that hasn't been reported?' he asked. 'If so, your 
theory's certainly wrong. The beam wasn't even pointing 
in the plane of the Solar System. And even if it 
were -- just look at this.' 
He switched on the vision screen and adjusted the 
controls. Against the velvet curtain of space was 
hanging a blue-white sphere, apparently composed of 
many concentric shells of incandescent gas. Even 
though its immense distance made all movement invisible, 
it was clearly expanding at an enormous rate. 
At its center was a blinding point of light -- the white 
dwarf star that the sun had now become. 
'You probably don't realize just how big that sphere 
is, 'said Alveron. 'Look at this.' 
He increased the magnification until the center portion 
of the nova was visible. Close to its heart were 
two minute condensations, one on either side of the 
nucleus. 
'Those are the two giant planets of the system. They 
have still managed to retain their existence -- after a 
fashion. And they were several hundred million miles 
from the sun. The nova is still expanding -- but it's 
already twice the size of the Solar System.' 
Rugon was silent for a moment. 
'Perhaps you're right,' he said, rather grudgingly. 
'You've disposed of my first theory. But you still 
haven't satisfied me.' 
He made several swift circuits of the room before 
speaking again. Alveron waited patiently. He knew 
the almost intuitive powers of his friend, who could 
often solve a problem when mere logic seemed insufficient. 
Then, rather slowly, Rugon began to speak again. 
'What do you think of this?' he said. 'Suppose we've 
completely underestimated this people? Orostron did 
it once-he thought they could never have crossed 
space, since they'd only known radio for two centuries. 
Hansur II told me that. Well, Orostron was quite 
wrong. Perhaps we're all wrong. I've had a look at the 
material that Klarten brought back from the transmitter. 
He wasn't impressed by what he found but 
it's a marvellous achievement for so short a time. There 
were devices in that station that belonged to civilizations 
thousands of years older. Alveron, can we follow 
that beam to see where it leads?' 
Alveron said nothing for a full minute. He had been 
more than half expecting the question, but it was not 
an easy one to answer. The main generators had gone 
completely. There was no point in trying to repair 
them. But there was still power available, and while 
there was power, anything could be done in time. It 
would mean a lot of improvisation, and some difficult 
maneuvers, for the ship still had its enormous initial 
velocity. Yes, it could be done, and the activity would 
keep the crew from becoming further depressed, now 
that the reaction caused by the mission's failure had 
started to set in. The news that the nearest heavy 
repair ship could not reach them for three weeks had 
also caused a slump in morale. 
The engineers, as usual, made a tremendous fuss. 
Again, as usual, they did the job in half the time they 
had dismissed as being absolutely impossible. Very 
slowly, over many hours, the great ship began to discard 
the speed its main drive had given it in as many 
minutes. In a tremendous curve, millions of miles in 
radius, the S9000 changed its course and the star fields 
shifted round it. 
The maneuver took three days, but at the end of that 
time the ship was limping along a course parallel to 
the beam that had once come from Earth. They were 
heading out into emptiness, the blazing sphere that 
had been the sun dwindling slowly behind them. By 
the standards of interstellar flight, they were almost 
stationary. 
For hours Rugon strained over his instruments, driving 
his detector beams far ahead into space. There were 
certainly no planets within many light-years; there was 
no doubt of that. From time to time Alveron came to 
see him and always he had to give the same reply: 
'Nothing to report.' About a fifth of the time Rugon's 
intuition let him down badly; he began to wonder if 
this was such an occasion. 
Not until a week later did the needles of the massdetectors 
quiver feebly at the ends of their scales. But 
Rugon said nothing, not even to his captain. He waited 
until he was sure, and he went on waiting until even 
the short-range scanners began to react, and to build up 
the first faint pictures on the vision screen. Still he 
waited patiently until he could interpret the images. 
Then, when he knew that his wildest fancy was even 
less than the truth, he called his colleagues into the 
control room. 
The picture on the vision screen was the familiar 
one of endless star fields, sun beyond sun to the very 
limits of the Universe. Near the center of the screen 
a distant nebula made a patch of haze that was difficult 
for the eye to grasp. 
Rugon increased the magnification. The stars flowed 
out of the field; the little nebula expanded until it 
filled the screen and then -- it was a nebula no longer. 
A simultaneous gasp of amazement came from all the 
company at the sight that lay before them. 
Lying across league after league of space, ranged in 
a vast three-dimensional array of rows and columns 
with the precision of a marching army, were thousands 
of tiny pencils of light. They were moving swiftly; 
the whole immense lattice holding its shape as a single 
unit. Even as Alveron and his comrades watched, the 
formation began to drift off the screen and Rugon had 
to recenter the controls. 
After a long pause, Rugon started to speak. 
'This is the race,' he said softly, 'that has known 
radio for only two centuries -- the race that we believed 
had crept to die in the heart of its planet. I have examined 
those images under the highest possible 
magnification. 
'That is the greatest fleet of which there has ever 
been a record. Each of those points of light represents 
a ship larger than our own. Of course, they are very 
primitive -- what you see on the screen are the jets of 
their rockets. Yes, they dared to use rockets to bridge 
interstellar space! You realize what that means. It 
would take them centuries to reach the nearest star. 
The whole race must have embarked on this journey 
in the hope that its descendants would complete it, 
generations later. 
'To measure the extent of their accomplishment, 
think of the ages it took us to conquer space, and the 
longer ages still before we attempted to reach the stars. 
Even if we were threatened with annihilation, could 
we have done so much in so short a time? Remember, 
this is the youngest civilization in the Universe. Four 
hundred thousand years ago it did not even exist. What 
will it be a million years from now?' 
An hour later, Orostron left the crippled mother 
ship to make contact with the great fleet ahead. As the 
little torpedo disappeared among the stars, Alveron 
turned to his friend and made a remark that Rugon 
was often to remember in the years ahead. 
'I wonder what they'll be like?' he mused. 'Will they 
be nothing but wonderful engineers, with no art or 
philosophy? They're going to have such a surprise 
when Orostron reaches them -- I expect it will be 
rather a blow to their pride. It's funny how all 
isolated races think they're the only people in the 
Universe. But they should be grateful to us; we're 
going to save them a good many hundred years of 
travel.' 
Alveron glanced at the Milky Way, lying like a veil 
of silver mist across the vision screen. He waved toward 
it with a sweep of a tentacle that embraced the 
whole circle of the galaxy, from the Central Planets to 
the lonely suns of the Rim. 
'You know,' he said to Rugon, 'I feel rather afraid of 
these people. Suppose they don't like our little Federation?' 
He waved once more toward the star-clouds that 
lay massed across the screen, glowing with the light of 
their countless suns. 
'Something tells me they'll be very determined 
people,' he added. 'We had better be polite to them. 
After all, we only outnumber them about a thousand 
million to one.' 
Rugon laughed at his captain's little joke. 
Twenty years afterward, the remark didn't seem 
funny.
