Armstrong's mind was rapidly splitting into two distinct portions, each trying to convince the other and neither wholly succeeding. He did not realize how far his morale had gone until he found himself holding his breath lest it conceal any

  sound from the darkness about him. Angrily, he cleared his mind of the rubbish that had been gathering there and turned once more to the immediate problem.

  There was no doubt that the road was slowly rising, and the silhouette of the horizon seemed much higher in the sky. The road began to twist, and suddenly he was aware of great rocks on either side of him. Soon only a narrow ribbon of sky was still visible, and the darkness became, if possible, even more intense.

  Somehow, he felt safer with the rock walls surrounding him: it meant that he was protected except in two directions. Also, the road had been leveled more carefully and it was easy to keep it. Best of all, he knew now that the journey was more than half completed.

  For a moment his spirits began to rise. Then, with maddening perversity, his mind went back into the old grooves again. He remembered that it was on the far side of Carver's Pass that the old clerk's adventure had taken place—if it had ever happened at all.

  In half a mile, he would be out in the open again, out of the protection of these sheltering rocks. The thought seemed doubly horrible now and he already felt a sense of nakedness. He could be attacked from any direction, and he would be utterly helpless. . . .

  Until now, he had still retained some self-control. Very resolutely he had kept his mind away from the one fact that gave some color to the old man's tale—the single piece of evidence that had stopped the banter in the crowded room back at the camp and brought a sudden hush upon the company. Now, as Armstrong's will weakened, he recalled again the words that had struck a momentary chill even in the warm comfort of the Base building.

  The little clerk had been very insistent on one point. He had never heard any sound of pursuit from the dim shape sensed, rather than seen, at the limit of his light. There was no scuffling of claws or hoofs on rock, nor even the clatter of displaced stones. It was as if, so the old man had declared in

  that solemn manner of his, "as if the thing that was following could see perfectly in the darkness, and had many small legs or pads so that it could move swiftly and easily over the rocks —like a giant caterpillar or one of the carpet-things of Kralkor II."

  Yet, although there had been no noise of pursuit, there had been one sound that the old man had caught several times. It was so unusual that its very strangeness made it doubly ominous. It was a faint but horribly persistent clicking.

  The old fellow had been able to describe it very vividly— much too vividly for Armstrong's liking now.

  "Have you ever listened to a large insect crunching its prey?" he said. "Well, it was just like that. I imagine that a crab makes exactly the same noise with its claws when it clashes them together. It was a—what's the word?—a chitinous sound."

  At this point, Armstrong remembered laughing loudly. (Strange, how it was all coming back to him now.) But no one else had laughed, though they had been quick to do so earlier. Sensing the change of tone, he had sobered at once and asked the old man to continue his story. How he wished now that he had stifled his curiosity!

  It had been quickly told. The next day, a party of skeptical technicians had gone into the no man's land beyond Carver's Pass. They were not skeptical enough to leave their guns behind, but they had no cause to use them, for they found no trace of any living thing. There were the inevitable pits and tunnels, glistening holes down which the light of the torches rebounded endlessly until it was lost in the distance—but the planet was riddled with them.

  Though the party found no sign of life, it discovered one thing it did not like at all. Out in the barren and unexplored land beyond the Pass they had come upon an even larger tunnel than the rest. Near the mouth of that tunnel was a massive rock, half embedded in the ground. And the sides of that rock had been worn away as if it had been used as an enormous whetstone.

  No less than five of those present had seen this disturbing rock. None of them could explain it satisfactorily as a natural formation, but they still refused to accept the old man's story. Armstrong had asked them if they had ever put it to the test. There had been an uncomfortable silence. Then big Andrew Hargraves had said: "Hell, who'd walk out to the Pass at night just for fun!" and had left it at that. Indeed, there was no other record of anyone walking from Port Sanderson to the camp by night, or for that matter by day. During the hours of light, no unprotected human being could live in the open beneath the rays of the enormous, lurid sun that seemed to fill half the sky. And no one would walk six miles, wearing radiation armor, if the tractor was available.

  Armstrong felt that he was leaving the Pass. The rocks on either side were falling away, and the road was no longer as firm and well packed as it had been. He was coming out into the open plain once more, and somewhere not far away in the darkness was that enigmatic pillar that might have been used for sharpening monstrous fangs or claws. It was not a reassuring thought, but he could not get it out of his mind.

  Feeling distinctly worried now, Armstrong made a great effort to pull himself together. He would try to be rational again; he would think of business, the work he had done at the camp—anything but this infernal place. For a while, he succeeded quite well. But presently, with a maddening persistence, every train of thought came back to the same point. He could not get out of his mind the picture of that inexplicable rock and its appalling possibilities. Over and over again he found himself wondering how far away it was, whether he had already passed it, and whether it was on his right or his left....

  The ground was quite flat again, and the road drove on straight as an arrow. There was one gleam of consolation: Port Sanderson could not be much more than two miles away. Armstrong had no idea how long he had been on the road. Unfortunately his watch was not illuminated and he could only guess at the passage of time. With any luck, the Canopus

  should not take off for another two hours at least. But he could not,be sure, and now another fear began to enter his mind—the dread that he might see a vast constellation of lights rising swiftly into the sky ahead, and know that all this agony of mind had been in vain.

  He was not zigzagging so badly now, and seemed to be able to anticipate the edge of the road before stumbling off it. It was probable, he cheered himself by thinking, that he was traveling almost as fast as if he had a light. If all went well, he might be nearing Port Sanderson in thirty minutes—a ridiculously small space of time. How he would laugh at his fears when he strolled into his already reserved stateroom in the Canopus, and felt that peculiar quiver as the phantom drive hurled the great ship far out of this system, back to the clustered star-clouds near the center of the Galaxy—back toward Earth itself, which he had not seen for so many years. One day, he told himself, he really must visit Earth again. All his life he had been making the promise, but always there had been the same answer—lack of time. Strange, wasn't it, that such a tiny planet should have played so enormous a part in the development of the Universe, should even have come to dominate worlds far wiser and more intelligent than itself!

  Armstrong's thoughts were harmless again, and he felt calmer. The knowledge that he was nearing Port Sanderson was immensely reassuring, and he deliberately kept his mind on familiar, unimportant matters. Carver's Pass was already far behind, and with it that thing he no longer intended to recall. One day, if he ever returned to this world, he would visit the Pass in the daytime and laugh at his fears. In twenty minutes now, they would have joined the nightmares of his childhood.

  It was almost a shock, though one of the most pleasant he had ever known, when he saw the lights of Port Sanderson come up over the horizon. The curvature of this little world was very deceptive: it did not seem right that a planet with

  a gravity almost as great as Earth's should have a horizon so close at hand. One day, someone would have to discover what la
y at this world's core to give it so great a density. Perhaps the many tunnels would help—it was an unfortunate turn of thought, but the nearness of his goal had robbed it of terror now. Indeed, the thought that he might really be in danger seemed to give his adventure a certain piquancy and heightened interest. Nothing could happen to him now, with ten minutes to go and the lights of the Port already in sight.

  A few minutes later, his feelings changed abruptly when he came to the sudden bend in the road. He had forgotten the chasm that caused his detour, and added half a mile to the journey. Well, what of it? he thought stubbornly. An extra half-mile would make no difference now—another ten minutes, at the most.

  It was very disappointing when the lights of the city vanished. Armstrong had not remembered the hill which the road was skirting; perhaps it was only a low ridge, scarcely noticeable in the daytime. But by hiding the lights of the Port it had taken away his chief talisman and left him again at the mercy of his fears.

  Very unreasonably, his intelligence told him, he began to think how horrible it would be if anything happened now, so near the end of the journey. He kept the worst of his fears at bay for a while, hoping desperately that the lights of the city would soon reappear. But as the minutes dragged on, he realized that the ridge must be longer than he imagined. He tried to cheer himself by the thought that the city would be all the nearer when he saw it again, but somehow logic seemed to have failed him now. For presently he found himself doing something he had not stooped to, even out in the waste by Carver's Pass.

  He stopped, turned slowly round, and with bated breath listened until his lungs were nearly bursting.

  The silence was uncanny, considering how near he must be to the Port. There was certainly no sound from behind him.

  Of course there wouldn't be, he told himself angrily. But he was immensely relieved. The thought of that faint and insistent clicking had been haunting him for the last hour.

  So friendly and familiar was the noise that did reach him at last that the anticlimax almost made him laugh aloud. Drifting through the still air from a source clearly not more than a mile away came the sound of a landing-field tractor, perhaps one of the machines loading the Canopus itself. In a matter of seconds, thought Armstrong, he would be around this ridge with the Port only a few hundred yards ahead. The journey was nearly ended. In a few moments, this evil plain would be no more than a fading nightmare.

  It seemed terribly unfair: so little time, such a small fraction of a human life, was all he needed now. But the gods have always been unfair to man, and now they were enjoying their little jest. For there could be no mistaking the rattle of monstrous claws in the darkness ahead of him.

  The Call of the Stars

  Down there on Earth the twentieth century is dying. As I look across at the shadowed globe blocking the stars, I can see the lights of a hundred sleepless cities, and there are moments when I wish that I could be among the crowds now surging and singing in the streets of London, Capetown, Rome, Paris, Berlin, Madrid. . . . Yes, I can see them all at a single glance, burning like fireflies against the darkened planet. The line of midnight is now bisecting Europe: in the eastern Mediterranean a tiny, brilliant star is pulsing as some exuberant pleasure ship waves her searchlights to the sky. I think she is deliberately aiming at us; for the past few minutes the flashes have been quite regular and startlingly bright. Presently I'll call the communications center and find out who she is, so that I can radio back our own greetings.

  Passing into history now, receding forever down the stream of time, is the most incredible hundred years the world has ever seen. It opened with the conquest of the air, saw at its mid-point the unlocking of the atom—and now ends with the bridging of space.

  (For the past five minutes I've been wondering what's happening to Nairobi; now I realize that they are putting on a mammoth fireworks display. Chemically fueled rockets may be obsolete out here—but they're still using lots of them down on Earth tonight.)

  The end of a century—and the end of a millennium. What will the hundred years that begin with two and zero bring? The planets, of course; floating there in space, only a mile away, are the ships of the first Martian expedition. For two years I have watched them grow, assembled piece by piece, as the space station itself was built by the men I worked with a generation ago.

  Those ten ships are ready now, with all their crews aboard, waiting for the final instrument check and the signal for departure. Before the first day of the new century has passed its noon, they will be tearing free from the reins of Earth, to head out toward the strange world that may one day be man's second home.

  As I look at the brave little fleet that is now preparing to challenge infinity, my mind goes back forty years, to the days when the first satellites were launched and the Moon still seemed very far away. And I remember—indeed, I have never forgotten—my father's fight to keep me down on Earth.

  There were not many weapons he had failed to use. Ridicule had been the first: "Of course they can do it," he had sneered, "but what's the point? Who wants to go out into space while there's so much to be done here on Earth? There's not a single planet in the Solar System where men can live. The Moon's a burnt-out slag heap, and everywhere else is even worse. This is where we were meant to live."

  Even then (I must have been eighteen or so at the time) I could tangle him up in points of logic. I can remember answering, "How do you know where we were meant to live, Dad? After all, we were in the sea for about a billion years before we decided to tackle the land. Now we're making the next big jump: I don't know where it will lead—nor did that first fish when it crawled up on the beach, and started to sniff the air."

  So when he couldn't outargue me, he had tried subtler pressures. He was always talking about the dangers of space travel, and the short working life of anyone foolish enough to get involved in rocketry. At that time, people were still

  scared of meteors and cosmic rays; like the "Here Be Dragons" of the old map makers, they were the mythical monsters on the still-blank celestial charts. But they didn't worry me; if anything, they added the spice of danger to my dreams.

  While I was going through college, Father was comparatively quiet. My training would be valuable whatever profession I took up in later life, so he could not complain— though he occasionally grumbled about the money I wasted buying all the books and magazines on astronautics that I could find. My college record was good, which naturally pleased him; perhaps he did not realize that it would also help me to get my way.

  All through my final year I had avoided talking of my plans. I had even given the impression (though I am sorry for that now) that I had abandoned my dream of going into space. Without saying anything to him, I put in my application to Astrotech, and was accepted as soon as I had graduated.

  The storm broke when that long blue envelope with the embossed heading "Institute of Astronautical Technology" dropped into the mailbox. I was accused of deceit and ingratitude, and I do not think I ever forgave my father for destroying the pleasure I should have felt at being chosen for the most exclusive—and most glamorous—apprenticeship the world has ever known.

  The vacations were an ordeal; had it not been for Mother's sake, I do not think I would have gone home more than once a year, and I always left again as quickly as I could. I had hoped that Father would mellow as my training progressed and as he accepted the inevitable, but he never did.

  Then had come that stiff and awkward parting at the spaceport, with the rain streaming down from leaden skies and beating against the smooth walls of the ship that seemed so eagerly waiting to climb into the eternal sunlight beyond the reach of storms. I know now what it cost my father to watch the machine he hated swallow up his only son: for I understand many things today that were hidden from me then.

  He knew, even as we parted at the ship, that he would never

  see me again. Yet his old, stubborn pride kept him from saying the only words t
hat might have held me back. I knew that he was ill, but how ill, he had told no one. That was the only weapon he had not used against me, and I respect him for it.

  Would I have stayed had I known? It is even more futile to speculate about the unchangeable past than the unforeseeable future; all I can say now is that I am glad I never had to make the choice. At the end he let me go; he gave up his fight against my ambition, and a little while later his fight with Death.

  So I said good-by to Earth, and to the father who loved me but knew no way to say it. He lies down there on the planet I can cover with my hand; how strange it is to think that of the countless billion human beings whose blood runs in my veins, I was the very first to leave his native world. . . .

  The new day is breaking over Asia; a hairline of fire is rimming the eastern edge of Earth. Soon it will grow into a burning crescent as the sun comes up out of the Pacific—yet Europe is preparing for sleep, except for those revelers who will stay up to greet the dawn.

  And now, over there by the flagship, the ferry rocket is coming back for the last visitors from the station. Here comes the message I have been waiting for: captain stevens presents HIS COMPLIMENTS TO THE STATION COMMANDER. BLAST-OFF WILL BE IN NINETY MINUTES; HE WILL BE GLAD TO SEE YOU ABOARD NOW.

  Well, Father, now I know how you felt: time has gone full circle. Yet I hope that I have learned from the mistakes we both made, long ago. I shall remember you when I go over there to the flagship Starfire and say good-by to the grandson you never knew.

  The Reluctant Orchid

  Science fiction, it has often been pointed out, is sadly lacking in humor. But something is worthwhile only if one can make fun of it, and this I set out to do in Tales from the "White Hart." There is nothing fictitious about the White Hart, or most of its clientele.
