You will have seen my yearly reports to your respected father on this subject. There have been no developments of interest for the past fifteen years, but the following message has just been received from our base on the Moon:

Rocket projectile, apparently atomically propelled, left Earth’s atmosphere today from northern landmass, travelling into space for one-quarter diameter of planet before returning under control.

To: Chief of State

Your comments, please.

K.K. V.

From: Chief of State.

To: President.

This means the end of our traditional policy.

The only hope of security lies in preventing the Terrestrials from making further advances in this direction. From what we know of them, this will require some overwhelming threat.

Since its high gravity makes it impossible for us to land on the planet, our sphere of action is restricted. The problem was discussed nearly a century ago by Anvar, and I agree with his conclusions. We must act
immediately
along those lines.

F.K.S.

From: President.

To: Secretary of State.

Inform the Council that an emergency meeting is convened for noon tomorrow.

K.K. V.

From: President.

To: C.B.E.P.S.

Twenty battleships should be sufficient to put Anvar’s plan into operation. Fortunately there is no need to arm them – yet. Report progress of construction to me weekly.

K.K. V.

From: C.B.E.P.S.

To: President.

Nineteen ships are now completed. The twentieth is still delayed owing to hull failure and will not be ready for at least a month.

Ranthe

From: President.

To: C.B.E.P.S.

Nineteen will be sufficient. I will check the operational plan with you tomorrow. Is the draft of our broadcast ready yet?

K.K. V.

From: C.B.E.P.S.

To: President.

Draft herewith:

People of Earth!

We, the inhabitants of the planet you call Mars, have for many vears observed your experiments towards achieving interplanetary travel.
These experiments must cease
. Our study of your race has convinced us that you are not fitted to leave your planet in the present state of your civilisation. The ships you now see floating above your cities are capable of destroying them utterly, and will do so unless you discontinue your attempts to cross space.

We have set up an observatory on your Moon and can immediately detect any violation of these orders. If you obey them, we will not interfere with you again. Otherwise, one of your cities will be destroyed every time we observe a rocket leaving the Earth’s atmosphere.

By order of the President and Council of Mars.

Ranthe

From: President.

To: C.B.E.P.S.

I approve. The translation can go ahead.

I will not be sailing with the fleet, after all. Report to me in detail immediately on your return.

K.K. V.

From: C.B.E.P.S.

To: President.

I have the honour to report the successful completion of our mission. The voyage to Earth was uneventful: radio messages from the planet indicated that we were detected at a considerable distance and great excitement had been aroused before our arrival. The fleet was dispersed according to plan and I broadcast the ultimatum. We left immediately and no hostile weapons were brought to bear against us.

I will report in detail within two days.

Ranthe

From: Secretary, Council of Scientists.

To: President.

The psychologists have completed their report, which is attached herewith.

As might be expected, our demands at first infuriated this stubborn and high-spirited race. The shock to their pride must have been considerable, for they believed themselves to be the only intelligent beings in the Universe.

However, within a few weeks there was a rather unexpected change in the tone of their statements. They had begun to realise that we were intercepting all their radio transmissions, and some messages have been broadcast directly to us. They state that they have agreed to ban all rocket experiments, in accordance with our wishes. This is as unexpected as it is welcome. Even if they are trying to deceive us, we are perfectly safe now that we have established the second station just outside the atmosphere. They cannot possibly develop spaceships without our seeing them or detecting their tube radiation.

The watch on Earth will be continued rigorously, as instructed.

Trescon

From: C.B.E.P.S.

To: President.

Yes, it is quite true that there have been no further rocket experiments in the last ten years. We certainly did not expect Earth to capitulate so easily!

I agree that the existence of this race now constitutes a permanent threat to our civilisation and we are making experiments along the lines you suggest. The problem is a difficult one, owing to the great size of the planet. Explosives would be out of the question, and a radioactive poison of some kind appears to offer the greatest hope of success.

Fortunately, we now have an indefinite time in which to complete this research, and I will report regularly.

Route: Transender II (via Schenectady).

The above papers, with others, were found in the ruins of what is believed to be the capital Martian city. (Mars Grid KL302895.) The frequent use of the ideograph for ‘Earth’ suggests that they may be of special interest and it is hoped that they can be translated. Other papers will be following shortly.

H. Forbes, Lt/Cdr.

[Added in manuscript]

Dear Max,

Sorry I’ve had no time to contact you before. I’ll be seeing you as soon as I get back to Earth.

Gosh! Mars
is
in a mess! Our Co-ordinates were dead accurate and the bombs materialised right over their cities, just as the Mount Wilson boys predicted.

We’re sending a lot of stuff back through the two small machines, but until the big transmitter is materialised we’re rather restricted, and, of course, none of us can return. So hurry up with it!

I’m glad we can get to work on rockets again. I may be old-fashioned, but being squirted through space at the speed of light doesn’t appeal to me!

Yours in haste,
Henry

This story stems from a lost original which also inspired ‘History Lesson’ (1949), although it would be difficult to find two more contrasting endings.

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 civilised 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 realise 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 of exploration. There are ten planets in the system about to be destroyed – and there is a civilisation 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 assure 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 S5060 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 incredibily 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 of time a civilisation has existed on one of these worlds – a civilisation 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 on to 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 civilisation 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 civilisation possessing radio could have protected itself against any rise of temperature that may have already occurred.

‘This ship and two tenders will each explore a section of the planet. Commander Torkalee will take Number One, Comander 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.
