only half as long as we do-that was the period of man's real greatness!" Nisa jerked up her head as she usually did when she disagreed. "'And when new ways of overcoming space have been discovered and people don't just force their way through it like we do, they'll say the same about you-those were the heroes who conquered space with their primitive methods!" The commander smiled happily and held out his hand to the girl. "They'll say it about you, too, Nisa!" "I'm proud to be here with you!" she answered, blushing. "And I'm prepared to give up everything if I can only travel into the Cosmos again and again!" "I know that," said Erg Noor, thoughtfully, "but that's not the way everybody thinks!" Feminine intuition gave her an insight into the thoughts of her commander. In his cabin there were two stereopor-traits, splendidly done in violet-gold tones. Both were of her, Veda Kong, a woman of great beauty, a specialist in ancient history; eyes of that same transparent blue as the skies above Earth looked out from under long eyebrows. Tanned by the sun, smiling radiantly, she had raised her hands to her ash-blonde hair. In the other picture she was seated, laughing heartily, on a ship's bronze gun, a relic of ancient days.... Erg Noor lost some of his impetuosity-he sat down slowly in front of the astronavigator. "If you only knew, Nisa, how brutally fate dealt with my dreams, there on Zirda!" he said suddenly, in a dull voice, placing his fingers cautiously on the lever controlling the anameson motors as though he intended accelerating the spaceship to the limit. "If Zirda had not perished and we had got our supplies of fuel," he continued, in reply to her mute question, "I would have led the expedition farther. That is what I had arranged with the Council. Zirda would have made the necessary report to Earth and Tantra would have continued its journey with those who wanted to go. The others would have waited for Algrab, it could have gone on to Zirda after its tour of duty here." "Who would have wanted to stay on Zirda?" exclaimed the girl, indignantly. "Unless Pour Hyss would. He's a great scientist though, wouldn't he be interested in gaining further knowledge?" "And you, Nisa?" "I'd go, of course." "Where to?" asked Erg Noor suddenly, fixing his eyes on the girl. "Anywhere you like, even..." and she pointed to a patch of abysmal blackness between two arms of the starry spiral of the Galaxy; she returned Noor's fixed stare with one equally determined, her lips slightly parted. "Oh, no, not as far as that! You know, Nisa, my dear little astronavigator, about eighty-five years ago. Cosmic Expedition No. 34, the so-called 'Three-Stage Expedition' left Earth. It consisted of three spaceships carrying fuel for each other and left Earth for the Lyra Constellation. The two ships that were not carrying scientists passed their anameson on to the third and then came back to Earth. That is the way mountain-climbers reached the tops of the highest peaks. Then the third ship, Parus...." "That's the ship that never returned!" whispered Nisa excitedly. "That's right, Parus didn't return. It reached its objective and was lost on the return journey after sending a message. The goal was the big planetary system of Vega, or Alpha Lyrae, a bright blue star that countless generations of human eyes have admired in the northern sky. The distance to Vega is eight parsecs and people had never been so far away from our Sun. Anyway, Parus got there. We do not know the cause of its loss, whether it was a meteoroid or an irreparable break-down. It is even possible that the ship is still moving through space and the heroes whom we regard as dead are still alive." "That would be terrible!" "Such is the fate of any spaceship that cannot maintain a speed close to that of light. It is immediately separated from the home planet by thousands of years." "What message did Parus send?" asked the girl. "There wasn't much of it. It was interrupted several times and then broke off altogether. I remember every word of it: 'I am Parus. I am Parus, travelling twenty-six years from Vega ... enough ... shall wait... Vega's four planets ... nothing more beautiful... what happiness...." "But they were calling for help, they wanted to wait somewhere!" "Of course they were calling for help, otherwise the spaceship wouldn't have used up the tremendous energy needed for the transmission. But nothing could be done, not another word was received from Parus." "'They were twenty-six independent years on their way back and the journey from Vega to the Sun is thirty-one years. They must have been somewhere near us, or even nearer to Earth." "Hardly, unless, of course, they exceeded the normal speed and got close to the quantum limit.8 That would have been very dangerous!" Briefly Erg Noor explained the mathematical basis for the destructive change that takes place in matter when it approaches the speed of light, but he noticed that the girl was not paying any great attention to him. "I understand all that!" she exclaimed the moment the commander had finished his explanation. "I would have realized it at once if your story of the loss of the spaceship hadn't taken my mind off it. Such losses are always terrible and one cannot become reconciled to them!" "Now you realize the chief thing in the communication," said Erg Noor gloomily. "They discovered some particularly beautiful worlds. I have long been dreaming of following the route taken by Parus; with modern improvements we can do it with one ship now: I've been living with a dream of Vega, the blue sun with the beautiful planets, ever since early youth." "To see such worlds ..." breathed Nisa with a breaking voice, "but to see them and return would take sixty terrestrial or forty dependent years ... and that's ... half a lifetime." "Great achievements demand great sacrifices. For me, though, it would not be a sacrifice. My life on Earth has only been a few short intervals between journeys through space. I was born on a spaceship, you know!" "How could that have happened?" asked the girl in amazement. "Cosmic Expedition No. 35 consisted of four ships. My mother was astronomer on one of them. I was born halfway to the binary star MN19026 +, 7AL and managed to Contravene the law twice over. Twice-firstly by being born on a spaceship and secondly because I grew up and was educated by my parents and not in a children's school. What else could they have done? When the expedition returned to Earth I was eighteen years old. I had learnt the art of piloting a spaceship and had acted as astronavigator in place of one who was taken ill. I could also work as a mechanic at the planetary or the anameson motors and all this was accepted as the Labours of Hercules I had to perform on reaching maturity." "Still I don't understand ..." began Nisa. ''About my mother? You'll understand when you get a bit older! Although the doctors didn't know it then, the Anti-T serum wouldn't keep.... Well, never mind what the reason was I was brought to a control tower like this one to look at the screens with my uncomprehending baby eyes and watch the stars dancing up and down on them. We were flying towards the Lupus Constellation where there was a binary star close to the Sun. The two dwarfs, one blue and the other orange, were hidden by a dark cloud. The first tiling that impinged on my infant consciousness was the sky over a lifeless planet that I observed from under the glass dome of a temporary station. The planets of double stars are usually lifeless on account of the irregularity of their orbits. The expedition made a landing and for seven months engaged in mineral prospecting. As far as I remember there were enormous quantities of platinum; osmium and iridium there. My first toys were unbelievably heavy building blocks made of iridium. And that sky, my first sky, was black and dotted with the pure lights of unwinking stars, and there were two suns of indescribable beauty, one a deep blue and the other a bright orange. I remember how their rays sometimes crossed and at those times our planet was inundated with so much jolly green light that I shouted and sang for joy!" Erg Noor stopped. "That's enough, I got carried away by my reminiscences and you have to sleep." "Go on, please do, I've never heard anything so interesting," Nisa begged him, but the commander was implacable. He brought a pulsating hypnotizer and, either because of his impelling eyes or the sleep-producing apparatus, the girl was soon fast asleep and did not wake up until the day before they were to enter the sixth circle. By the cold look on the commander's face Nisa Greet realized that Algrab had not shown up. "You woke up just at the right time!" he said as soon as Nisa had taken her electric and wave baths and returned ready for work. "Switch on the animation music and light. For everybody!" Swiftly Nisa pressed a row of buttons sending intermittent bursts of light accompanied by a specific music of low, vibrant chords that gradually increased in intensity, to all the cabins where members of the Cosmic expedition were sleeping. This initiated the gradual awakening of the inhibited nervous system to bring it back to its normal active state. Five hours later all the members of the expedition gathered in the control tower; they had by then fully recovered from their sleep and had taken food and nerve stimulants. News of the loss of the auxiliary spaceship was received in different ways by different people. As Erg Noor expected, the expedition was equal to the occasion. Not a word of despair, not a glance of fear. Pour Hyss, who had not shown himself particularly brave on Zirda heard the news without a tremor. Louma Lasvy, the expedition's young physician, went slightly pale and secretly licked her dry lips. "To the memory of our lost comrades!" said the commander as he switched on the screen of a projector showing Algrab, a photograph that had been taken before Tantra took off. All rose to their feet. On the screen one after another came the photographs of the seven members of Algrab's crew, some serious, some smiling. Erg Noor named each of them in turn and the travellers gave him the farewell salute. Such was the custom of the astronauts. Spaceships that set off together always carried photographs of all the people of the expedition. When a ship disappeared it might keep travelling in Cosmic space for a long time with its crew still alive. But this made no difference, the ship would never return. There was no real possibility of searching for the ship and rendering it aid. Minor faults never, or seldom, occurred and were easily repaired, but a serious break-down in the machinery had never been successfully repaired in the Cosmos. Sometimes ships, like Parus, managed to send a last message, but in the majority of cases such messages did not reach their destination on account of the great difficulty of directing them. The Great Circle had, for thousands of years, been investigating exact routes for its transmissions and could vary them by directing them from planet to planet. The spaceships were usually in unexplored areas where the direction for a message could only be guessed. There was a conviction amongst astronauts that there existed in the Cosmos certain neutral fields or zero areas in which all radiation and all communications sank like stones in water. Astrophysicists, however, regarded the zero areas to be nothing more than the idle invention of Cosmic travellers who were, in general, inclined to monstrous fantasies. After that sad ceremony and a very short conference, Erg Noor turned Tantra in the direction of Earth and switched on the anameson motors. Forty-eight hours later they were switched off again and the spaceship began to approach its own planet at the rate of 21,000 million kilometres in every twenty-four hours. The journey back to the Sun would take about six terrestrial, or independent, years. Everybody was busy in the control tower and in the ship's combined library and laboratory where a new course was being computed and plotted on the charts. The task was to fly the whole six years and use anameson only for purposes of correcting the ship's course. In other words the spaceship had to be flown with as little loss of acceleration as possible. Everybody was worried about the unexplored area 344 +2U that lay between the Sun and Tantra. There was no way of avoiding it: on both sides of it, as far as the Sun, lay belts of free meteoroids and, apart from that, they would lose velocity in turning the ship. Two months later the computation of the line of flight had been completed. Tantra began to describe a long, flat curve. The wonderful ship was in excellent condition and her speed was kept within the computed limits. Now nothing but time, about four dependent years, separated the ship from its home. Erg Noor and Nisa Creet finished their watch and, dead tired, started their period of long sleep. Together with them two astronomers, the geologist, biologist, physician and four engineers departed into temporary forgetful-ness. The watch was taken over by an experienced astronavigator, Pel Lynn, who was on his second expedition, assisted by astronomer Ingrid Dietra and electronic engineer Kay Bear who had volunteered to join them. Ingrid, with Pel Lynn's consent, often went away to the library adjoining the control tower. She and her old friend, Kay Bear, were writing a monumental symphony. Death of a Planet, inspired by the tragedy of Zirda. Pel Lynn, whenever he grew tired of the hum of the instruments and his contemplation of the black void of the Cosmos, left Ingrid at the control desk and plunged into the thrilling task of deciphering puzzling inscriptions brought from a planet in the system of the nearest stars of the Centaur whose inhabitants had mysteriously quit it. He believed in the success of his impossible undertaking.... Twice again watches were changed, the spaceship had drawn ten billion kilometres nearer Earth and still the anameson motors had only been run for a few hours. One of Pel Lynn's watches, the fourth since Tantra had left the place where she was to have met Algrab, was coming to an end. Ingrid Dietra, the astronomer, had finished a calculation and turned to Pel Lynn who was watching, with melancholy mien, the constant flickering of the red arrows on the graded blue scales of the gravitation meters. The usual sluggishness of psychic reaction that not even the strongest people could avoid made itself felt during the second half of the watch. For months and years the spaceship had been automatically piloted along a given course. If anything untoward had happened, something that the electronic machines were incapable of dealing with, it would have meant the loss of the ship, for human intervention could not have saved it since the human brain, no matter how well trained it may be, cannot react with the necessary alacrity. "In my opinion we are already deep in the unknown area 344 - 2U. The commander wanted to take over the watch himself when we reached it," said Ingrid to the astronavigator. Pel Lynn glanced up at the counter that marked off the days. "Another two days and we change watches. So far there doesn't seem to be anything to worry about. Shall we see the watch through?" Ingrid nodded assent. Kay Bear came into the control tower from the stern of the ship and took his usual seat beside the equilibrium mechanism. Pel Lynn yawned and stood up. "I'll get some sleep for a couple of hours," he said to Ingrid. She got up obediently and went forward to the control desk. Tantra was travelling smoothly in an absolute vacuum. Not a single meteoroid, not even at a great distance, had been registered by the super-sensitive Voll Hoad detectors. The spaceship's course now lay somewhat to one side of the Sun, about one and a half flying years. The screens of the forward observation instruments were of an astounding blackness, it seemed as though the spaceship was diving into the very heart of universal darkness. The side telescopes still showed needles of light from countless stars. Ingrid's nerves tingled with a strange sensation of alarm. She returned to her machines and telescopes, again and again checked their readings as she mapped the unknown area. Everything was quiet but still Ingrid could not take her eyes off the malignant blackness ahead of the ship. Kay Bear noticed her anxiety and for a long time studied and listened to the instruments. "I don't see anything," he said at last, "aren't you imagining things?" "I don't know why, but that unusual blackness ahead of us bothers me. It seems to me that our ship is diving straight into a dark nebula." "There should be a dark cloud here," Kay Bear agreed, "but we shall only scratch the edge of it. That's what was calculated! The strength of the gravitational field is increasing slowly and regularly. On our way through this area we should pass close to some centre of gravity. What does it matter whether it's light or dark?" "That's true enough," admitted Ingrid, more calmly. "We've got the finest commander and officers there are. We're proceeding along a set course even faster than was computed. If there are no changes we'll be out of our trouble and we'll get safely to Triton despite our short supply of anameson." Even at the thought of the spaceship's station on Triton, Neptune's satellite on the fringe of the solar system, Ingrid felt much happier. To reach Triton would mean that they were home. "I was hoping we'd be able to work on the symphony together but Lynn's asleep. He'll sleep six or seven hours so I'll think over the orchestration of the coda of the second movement-you know, the place where we couldn't find a means of expressing the integrated accession of the menace. This piece...." Kay sang a few notes. "Tee-ee-e, tee-ee-e, ta-rara-ra," came the immediate response from the very walls of the control tower. Ingrid started and looked round, but a moment later realized what it was. There had been an increase in the force of gravity and the instruments had responded by changing the melody of the artificial gravitation apparatus. "What an amusing coincidence," laughed Ingrid, with an air of guilt. "There is stronger gravitation, as there should be in a black cloud. Now you can calm yourself altogether and let Lynn sleep." Kay Bear left the control tower and entered the brightly-lit library where he sat down at a tiny electronic violin-piano. He was soon deeply immersed in his work and, no doubt, several hours must have passed before the hermetically sealed door of the library flew open and Ingrid appeared. "Kay, please wake up Lynn." "What's wrong?" "The strength of the gravitation field is much more than was computed." "What is ahead of us?" "The same blackness!" Ingrid went out. Kay Bear woke the astronavigator, who jumped up and ran to the instruments in the control tower. "There's nothing especially dangerous. Only where does such a gravitational field come from in this area? It's too strong for a black cloud and there are no stars here." Lynn thought for a time and then pressed the knob to awaken the commander of the expedition and after another moment's thought pressed the knob of Nisa Creel's cabin as well. "If nothing extraordinary happens they can simply take over their watch," Lynn explained to the anxious Ingrid. "And if something does happen? Erg Noor won't return to normal for another five hours. What shall we do?" "Wait quietly," answered the astronavigator. "What can happen here in five hours when we are so far from all stellar systems?" The tone of the measuring instruments grew lower and lower telling of the constantly changing conditions of the flight. The tense waiting dragged out endlessly. Two hours dragged by so slowly that they seemed like a whole watch. Outwardly Pel Lynn was still calm but Ingrid's anxiety had already infected Kay Bear. He kept looking at the control-tower door expecting Erg Noor to appear with his usual rapid movements although he knew that the awakening from prolonged sleep is a lengthy process. The long ringing of a bell caused them all to start. Ingrid grasped hold of Kay Bear. Tantra was in danger! The gravitation was double the computed figure! The astronavigator turned pale. The unexpected bad happened and an immediate decision was essential. The fate of the spaceship was in his hands. The steadily increasing gravitational pull made a reduction in speed necessary, both because of increasing weight in the ship and an apparent accumulation of solid matter in the ship's path. But after reducing speed what would they use for further acceleration? Pel Lynn clenched his teeth and turned the lever that started the ion trigger motors used for braking. Gong-like sounds disturbed the melody of the measuring instruments and drowned the alarming ring of those recording the ratio of gravitational pull to velocity. The ringing ceased and the indicators showed that speed had been reduced to a safe level and was normal for the growing gravitation. But no sooner had Pel Lynn switched off the brake motors than the bells began ringing again. Obviously the spaceship was flying directly into a powerful gravitation centre which was slowing it down. The astronavigator did not dare change the course that had been plotted with such great difficulty and absolute precision. He used the planetary motors to brake the ship again although it was already clear that there had been an error in plotting the course and that it lay through an unknown mass of matter. "The gravitational field is very great," said Ingrid softly, "perhaps...." "We must slow down still more so as to be able h turn," exclaimed the navigator, "but what can we accelerate with after that?..." There was a note of fatal hesitancy in his words. "We have already passed the zone of outer vortices," Ingrid told him, "gravitation is increasing rapidly all the time.'' The frequent clatter of the planet motors resounded through the ship; the electronic ship's pilot switched them on automatically as it felt a huge accumulation of solid matter in front of them. Tantra began to pitch and toss. No matter how much the ship's speed was reduced the people in the control tower began to lose consciousness. Ingrid fell to her knees. Pel Lynn, sitting in his chair, tried to raise a head as heavy as lead. Kay Bear experienced a mixture of unreasoning brute fear and puerile hopelessness. The thuds of the motors increased in frequency until they merged into a continual roar-the electronic brain had taken up the struggle in place of its semi-conscious masters; it was a powerful brain but it had its limits, it could not foretell all possible complications and find a way out of unusual situations. The tossing abated. The indicators showed that the supply of ion charges for the motors was dropping with catastrophic rapidity. As Pel Lynn came to he realized that the strange increase of gravity was taking place so fast that urgent measures had to be taken to stop the ship and then make a complete change of course away from the black void. Pel Lynn turned the handle switching on the anameson motors. Four tall cylinders of boron nitride that could be seen through a slit in the control desk were lit up from inside. A bright green flame beat inside them with lightning speed, it flowed and whirled in four tight spirals. Up forward, in the nose of the spaceship, a strong magnetic field enveloped the motor jets, saving them from instantaneous destruction. The astronavigator moved the handle farther-through the whirling green wall of light a directing ray appeared, a greyish stream of K-particles." Another movement and the grey stream was cut by a blinding flash of violet lightning, a signal that the anameson had begun its tempestuous emission. The huge bulk of the spaceship responded with an almost inaudible, unbearable, high-frequency vibration.... Erg Noor had eaten the necessary amount of food and was lying half asleep enjoying the indescribably pleasurable sensation of an electric nerve massage. The veil of forgetfulness that still covered mind and body left him very slowly. The music of animation changed to a major key and to a rhythm that increased in rapidity.... Suddenly something evil coming from without interrupted the joy of awakening from a ninety-day sleep. Erg Noor realized that he was commander of the expedition and struggled desperately to get back to normal consciousness. At last he recognized the fact that the spaceship was being braked and that the anameson motors were switched on, all of which meant that something serious had occurred. He tried to get up. His body still would not obey his will, his legs doubled under him and he collapsed like a sack on the floor of his cabin. After some time he managed to crawl to the door and open it. Consciousness was breaking through the mist of sleep-in the corridor he rose on all fours and made his way into the control tower. The people staring at the screens and instrument dials looked round in alarm and then ran to their commander. He was not yet able to stand but he muttered: "The screens ... the forward screen ... switch over to infrared ... stop the motors!" The borason cylinders were extinguished at the same time as the vibration of the ship's hull ceased. A gigantic star, burning with a dull reddish-brown light, appeared on the forward starboard screen. For a moment they were all flabbergasted and could not take their eyes off the enormous disc that emerged from the darkness directly ahead of the spaceship. "Oh, what a fool!" exclaimed Pel Lynn bitterly, "I was sure we were in a dark nebula! And that's...." "An iron star!" exclaimed Ingrid Dietra in horror. Erg Noor, holding on to the back of a chair, stood up. His usually pale face had a bluish tinge to it but his eyes gleamed brightly with their usual fire. "Yes, that's an iron star," he said slowly and the eyes of all those in the room turned to him in fear and hope, "the terror of astronauts! Nobody suspected that there would be one in this area." "I only thought about a nebula," Pel Lyn said softly and guiltily. "A dark nebula with such a gravitational field would contain comparatively large solid particles and Tantra would have been destroyed already. It would be impossible to avoid a collision in such a swarm," said the commander in a calm firm voice. "But these sharp gravitational changes and these vortex things-aren't they a direct indication of a cloud?" "Or that the star has a planet, perhaps more than one...." The astronavigator bit his lip so badly that it began to bleed. The commander nodded his head encouragingly and himself pressed the buttons to awaken the others. "A report of observations as quickly as possible! We'll work out the gravitation contours." The spaceship began to rock again. Something flashed across the screen with colossal speed, something of terrific size that passed behind them and disappeared. "There's the answer, we've overtaken the planet. Hurry up, hurry up, get the work done!" The commander's glance fell on the fuel supply indicator. His hands gripped the back of the chair more tightly, he was going to say something but refrained. CHAPTER TWO. EPSILON TUCANAE The faint tinkle of glass that came from the table was accompanied by orange and blue lights. Varicoloured lights sparkled up and down the transparent partition. Darr Veter, Director of the Outer Stations of the Great Circle, was observing the lights on the Spiral Way. Its huge arc curved into the heights and scored a dull yellow line along the sea-coast. Keeping his eyes on the Way, Darr Veter stretched out his hand and turned a lever to point M, ensuring himself solitude for meditation. A great change had on that day come into his life. His successor Mven Mass, chosen by the Astronautical Council, had arrived that morning from the southern residential belt. They would carry out his last transmission round the Circle together and then ... it was precisely this "then" that had not yet been decided upon. For six years he had been doing a job that required superhuman effort, work for which the Council selected special people, those who were outstanding for their splendid memories and encyclopaedic knowledge. When attacks of complete indifference to work and to life began recurring with ominous frequency-and this is one of the most serious ailments in man-he had been examined by Evda Nahl, a noted psychiatrist. A tried remedy-sad strains of minor music in a room of blue dreams saturated with pacifying waves-did not help. The only thing left was to change his work and take a course of physical labour, any sort of work that required daily, hourly muscular effort. His best friend, Veda Kong, the historian, had offered him an opportunity to do archaeological work with her. Machines could not do all the excavation work, the last stages required human hands. There was no lack of volunteers but still Veda had promised him a long trip to the region of the ancient steppes where he would be close to nature. If only Veda Kong ... but of course, he knew the whole story. Veda was in love with Erg Noor, Member of the Astronautical Council and Commander of Cosmic Expedition No. 37. There should have been a message from Erg Noor -from the planet Zirda he should have reported and said whether he was going farther. But if no message had come -and all space nights were computed with the greatest precision-then ... but no, he must not think of winning Veda's love! The Vector of Friendship, that was all, that was the greatest tie that there could be between them. I Nevertheless he would go and work for her. Darr Veter moved a lever, pressed a button and the room was flooded with light. A crystal glass window formed I one of the walls of a room situated high above land and sea, giving a view over a great distance. With a turn of another lever Darr Veter caused the window to drop inwards leaving the room open to the starry sky; the metal frame of the window shut out from his view the lights of the Spiral Way and the buildings and lighthouses on the sea-coast. Veter's eyes were fixed on the hands of the galactic clock with three concentric rings marked in subdivisions. The transmission of information round the Great Circle followed galactic time, once in every hundred-thousandth of a galactic second, or once in eight days, 45 times a year according to terrestrial time. One revolution of the Galaxy around its axis was one day of galactic time. The next and, for him, the last transmission would be at 9 a.m. Tibetan Mean Time or at 2 a.m. at the Mediterranean Observatory of the Council. A little more than two hours still remained. The instrument on the table tinkled and flashed again. A man in light-coloured clothing made of some material with a silk-like sheen appeared from behind the partition. "We are ready to transmit and receive," he said briefly, showing no outward signs of respect although in his eyes one could read admiration for his Director. Darr Veter did not say a word, nor did his assistant who stood there in a proud, unrestrained pose. "In the Cubic Hall?" asked Veter, at last, and, getting an answer in the affirmative, asked where Mven Mass was. "He is in the Morning Freshness Room, getting tuned up after his journey and, apart from that, I think he's a bit excited." "I'd be excited myself if I were in his place!" said Darr Veter, thoughtfully. "That's how I felt six years ago." The assistant was flushed from his effort to preserve his outward calm. With all the fire of youth he was sorry for his chief, perhaps he even realized that some day he, too, would live through the joys and sorrows of great work and great responsibility. The Director of the Outer Stations did not in any way show his feelings for to do so at his age was not considered decent. "When Mven Mass appears, bring him straight to me." The assistant left the room. Darr Veter walked over to one corner where the transparent partition was blackened from floor to ceiling and with an easy movement opened two shutters in a panel of polished wood. A light appeared, coming from somewhere in the depths of a mirror-like screen. It did not, however, possess the gloss of a mirror -it gave the impression of a long corridor leading into the far distance. Using selected switches the Director of the Outer Stations switched on the Vector of Friendship, a system of direct communication between people linked by the ties of profound friendship that enabled them to contact each other at any moment. The Vector of Friendship was connected with a number of places where the person concerned was likely to be-his house, his place of work, his favourite recreation centre. The screen grew light and in the depths there appeared familiar panels with columns of coded titles of electronic films that had succeeded the ancient photocopies of books. When all mankind adopted a single alphabet-it was called the linear alphabet because there were no complicated signs in it-it became easy to film even the old books, so that eventually the process was fully mechanized. The blue, green and red stripes were the symbols of the central film libraries where scientific research works were stored, works that had for centuries been published only in a dozen copies. It was merely necessary to select the a code number and symbols and the film library would transmit, automatically, the full text of the book. This machine was Veda's private library. A snap of switches and the picture faded, it was followed by another room which was also empty. Another switch connected the screen with a hall in which stood a number of dimly lighted desks. The woman seated at the nearest desk raised her head and Darr Veter recognized the thick, widely separated eyebrows and the sweet, narrow face with its grey eyes. As she smiled, white teeth flashed in a big mouth with bold lines and her cheeks were chubbily rounded on either side of a slightly snub nose with a childish, round tip to it that made the face gentle and kindly. "Veda, there are two hours left. You have to change and I would like you to come to the observatory a little before time." The woman on the screen raised her hands to her thick, ash-blonde hair. "I obey, my Veter," she smiled. "I'm going home." Veter's ear was not deceived by the gayness of her tones. "Brave Veda, calm yourself. Everybody who speaks to the Great Circle had to make a first appearance." "Don't waste words consoling me," said Veda Kong, raising her head with a stubborn gesture. "I'll be there soon. The screen went dark. Darr Veter closed the shutters and turned to meet his successor. Mven Mass entered the room with long strides. The cast of his features and his smooth, dark-brown skin showed that he was descended from African ancestors. A white mantle fell from his powerful shoulders in heavy folds. Mven Mass took both Darr Veter's hands in his strong, thin ones. The two Directors of the Outer Stations, the new and the old, were both very tall. Veter, whose genealogy led back to the Russian people, seemed broader and more massive than the graceful African. "It seems to me that something important ought to happen today," began Mven Mass, with that trusting sincerity that was typical of the people who lived in the Era of the Great Circle. Darr Veter shrugged his shoulders. ''Important things will happen for three people. I am handing over my work, you are taking it from me and Veda Kong will speak to the Universe for the first time." "She is beautiful?" responded Mven Mass, half questioning, half affirming. "You'll see her. By the way, there's nothing special about today's transmission. Veda will give a lecture on our history for planet KRZ 664456 + BS 3252." Mven Mass made an astonishingly rapid mental calculation. "Constellation of the Unicorn, star Ross 614, its planetary system has been known from time immemorial but has never in any way distinguished itself. I love the old names and old words," he added with a scarcely detectable note of apology. "The Council knows how to select people," Darr Veter thought to himself. Aloud he said: "Then you'll get on well with Junius Antus, the Director of the Electronic Memory Machines. He calls himself the Director of the Memory Lamps. He is not thinking of the lamps they used for light in ancient days but of those first electronic devices in clumsy glass envelopes with the air pumped out of them; they looked just like the electric lamps of those days." Mven Mass laughed so heartily and frankly that Darr Veter could feel his liking for the man growing fast. "Memory lamps!
