  “Cold had killed them. They had heating arrangements, devices intended to maintain forever the normal temperature despite the wildest variations of the weather. But in every electrical machine, resistances, balance resistances, and induction coils, balance condensers, and other inductances. And cold, stark, spatial cold, through ages, threw them off. Despite the heaters, cold crept in colder—cold that made their resistance balances and their induction coils superconductors! That destroyed the city, Superconduction—like the elimination of friction, on which all things must rest. It is a drag and a thing engineers fight forever. Resistance and friction must finally be the rest and the base of all things, the force that holds the great bed bolts firm and the brakes that stop the machines when needed.

  “Electrical resistance died in the cold and wonderful machines stopped for the replacement of defective parts. And when they were replaced, they, too, were defective. For what months must that constant stop—replacement—start—stop—replacement have gone on before, at last defeated forever, those vast machines must bow in surrender to the inevitable? Cold has defeated them by defeating and removing the greatest obstacle of the engineers that built them resistance.

  “They must have struggled forever—as we would say—through a hundred billion years against the encroaching harshness of nature, forever replacing worn, defective parts. At last, defeated forever, the great power plants, fed by dying atoms, had been forced into eternal idleness and cold. Cold conquered them at last.

  “They didn’t blow up. Nowhere did I see a wrecked machine; always they had stopped automatically when the defective resistances made it impossible to continue. The stored energy that was meant to re-start those machines after repairs had been made had long since leaked out. Never again could they move, I knew.

  “I wondered how long they had been, how long they had gone on and on, long after the human need of them had vanished. For that vast city contained only a very few humans at the end. What untold ages of Jonely functioning perfection had stretched behind those at-last-defeated mechanisms?

  “I wandered out, to see perhaps more, before the necessary end came to me, too. Through the city of death. Everywhere little self-contained machines, cleaning machines that had kept that perfect city orderly and neat stood helpless and crushed by eternity and cold. They must have continued functioning for years after the great central power stations failed, for each contained its own store of energy, needing only occasional recharge from the central stations.

  “I could see where breaks had occurred in the city, and, clustered about those breaks were motionless repair machines, their mechanisms in positions of work, the debris cleared away and carefully stacked on motionless trucks. The new beams and plates were partly attached, partly fixed and left, as the last dregs of their energy was fruitlessly expended in the last, dying attempts of that great body to repair itself. The death wounds lay unmended.

  “I started back up. Up to the top of the city. It was a long climb, an infinite, weary climb, up half a mile of winding ramps, past deserted, dead homes; past, here and there, shops and restaurants; past motionless little automotive passenger cars.

  “Up and up, to the crowning gardens that lay stiff and brittle and frozen. The breaking of the roof must have caused a sudden chill, for their leaves lay green in sheaths of white, frozen air. Brittle glass, green and perfect to the touch. Flowers, blooming in wonderful perfection showed still; they didn’t seem dead, but it didn’t seem they could be otherwise under the blanket of cold.

  “Did you ever sit up with a corpse?” Bob looked up at us—through us. “I had to once, in my little home town where they always did that. I sat with a few neighbors while the man died before my eyes. I knew he must die when I came there. He died—I sat there all night while the neighbors filed out, one by one, and the quiet settled. The quiet of the dead.

  “I had to again. I was sitting with a corpse then. The corpse of a dead world in a dead universe, and the quiet didn’t have to settle there; it had settled a billion years ago, and only my coming had stirred those feeble, protesting ghosts of eon-dead hopes of that planet to softly whining protest—protest the wind tried to sob to me, the dead wind of the dead gases. I’ll never be able to call them inert gases again. I know. I know they are dead gases, the dead gases of dead world.

  “And above, through the cracked crystal of the roof, the dying suns looked down on the dead city. I couldn’t stay there. I went down. Down under layer after layer of buildings, buildings of gleaming metal that reflected the dim, blood light of the Sun outside in carmine stains. I went down and down, down to the machines again. But even there hopelessness seemed more intense. Again I saw that agonizing struggle of the eternally faithful machines trying to repair themselves once more to serve the masters who were dead a million million years. I could see it again in the frozen exhausted postures of the repair machines, stilled forever in their hopeless endeavors, the last poor dregs of energy spilled in fruitless conflict with time.

  “It mattered little. Time itself was dying now, dying with the city and the planet and the universe he had killed.

  “But those machines had tried so hard to serve again—and failed. Now they could never try again. Even they—the deathless machines—were dead.

  “I went out again, away from those machines, out into the illimitable corridors, on the edge of the city. I could not penetrate far before the darkness became as absolute as the cold. I passed the shops where goods, untouched by time in this cold still beckoned those strange humans, but humans for all that; beckoned the masters of the machines that were no more. I vaguely entered one to see what manner of things they used in that time.

  “I nearly screamed at the motion of the thing in there, heard dimly through my suit the strangely softened sounds it made in the thin air. I watched it stagger twice—and topple. I cannot guess what manner of storage cells they had—save they were marvelous beyond imagination. That stored energy that somehow I had released by entering was some last dreg that had remained through a time as old as our planet now. Its voice was stilled forever. But it drove me out—on.

  “It had died while I watched. But somehow it made me more curious. I wondered again, less oppressed by utter death. Still, some untapped energy remained in this place, stored unimaginably. I looked more keenly, watched more closely. And when I saw a screen in one office, I wondered. It was a screen. I could see readily it was a television of some type. Exploratively, I touched a stud. Sound! A humming, soft sound!

  “To my mind leaped a picture of a system of these. There must be—interconnected—a vast central office somewhere with vaster accumulator cells, so huge, so tremendous in their power once, that even the little microfraction that remained was great. A storage system untouchable to the repair machines—the helpless, hopeless power machines.

  “In an instant I was alive again with hope. There was a strange series of studs and dials, unknown devices. I pulled back on the stud I had pressed, and stood trembling, wondering. Was there hope?

  “Then the thought died. What hope? The city was dead. Not merely that. It had been dead, dead for untold time. Then the whole planet was dead. With whom might I connect? There were none on the whole planet, so what mattered it that there was a communication system.

  “I looked at the thing more blankly. Had there been—how could I interpret its multitudinous devices? There was a thing on one side that made me think of a telephone dial for some reason.

  A pointer over a metal sheet engraved with nine symbols in a circle under the arrow of the pointer. Now the pointer was over what was either the first or the last of these.

  “Clumsily, in these gloves, I fingered one of the little symbol buttons inlaid in the metal. There was an unexpected click, a light glowed on the screen, a lighted image! It was a simple projection—but what a projection! A three-dimensional sphere floated, turned slowly before my eyes, turning majestically. And I nearly fell as understanding flooded me abruptly. The pointer was a select
or! The studs beneath the pointer I understood! Nine of them. One after the other I pressed, and nine spheres—each different—swam before me.

  “And right there I stopped and did some hard thinking. Nine spheres. Nine planets. Earth was shown first—a strange planet to me, but one I knew from the relative size and the position of the pointer must be Earth—then, in order, the other eight.

  “Now—might there be life? Yes. In those nine worlds there might be, somewhere.

  “Where? Mercury—nearest the Sun? No, the Sun was too dead, too cold, even for warmth there. And Mercury was too small. I knew, even as I thought, that I’d have one good chance because whatever means they had for communication wouldn’t work without tremendous power. If those incredible storage cells had the power for even one shot, they had no more. Somehow I guessed that this apparatus might incorporate no resistance whatever. Here would be only very high frequency alternating current, and only condensers and inductances would be used in it. Supercooling didn’t bother them any. It improved them. Not like the immense direct-current power machinery.

  “But where to try? Jupiter? That was big. And then I saw what the solution must be. Cold had ruined these machines, thrown them off by making them too-perfect conductors. Because they weren’t designed to defend themselves against spatial cold. But the machines—if there were any—on Pluto for instance, must originally have been designed for just such conditions! There it had always been cold. There it always would be cold.

  “I looked at that thing with an intensity that should have driven my bare eyesight to Pluto. It was a hope. My only hope. But—how to signal Pluto? They could not understand! If there were any ‘they.’

  “So I had to guess—and hope. Somehow, I knew, there must be some means of calling the intelligent attendant, that the user might get aid. There was a bank of little studs—twelve of them—with twelve symbols, each different, in the center of the panel, grouped in four rows of three. I guessed. Duodecimal system.

  “Talk of the problems of interplanetary communication! Was there ever such a one? The problem of an anachronism in the city of the dead on a dead planet, seeking life somewhere, somehow.

  “There were two studs, off by themselves, separate from the twelve—one green, one red. Again I guessed. Each of these had a complex series of symbols on it, so I turned the pointer on the right to Pluto, wavered, and turned it to Neptune. Pluto was further. Neptune had been cold enough; the machines would still be working there, and it would be, perhaps, less of a strain on the dregs of energy that might remain.

  “I depressed the green symbol hoping I had guessed truly, that red still meant danger, trouble and wrongness to men when that was built—that it meant release and cancellation for a wrongly pressed key. That left green to be an operative call signal.

  “Nothing happened. The green key alone was not enough. I looked again, pressed the green key and that stud I had first pressed.

  “The thing hummed again. But it was a deeper note, now, an entirely different sound, and there was a frenzied clicking inside. Then the green stud kicked back at me. The Neptune key under the pointer glowed softly; the screen began to shimmer with a grayish light. And, abruptly, the humming groaned as though at a terrific overload; the screen turned dull; the little signal light under Neptune’s key grew dim. The signal was being sent—hurled out.

  “Minute after minute I stood there, staring. The screen grew very slowly, very gently, duller, duller. The energy was fading. The last stored driblet was being hurled away—away into space. ‘Oh,’ I groaned. ‘It’s hopeless—hopeless to—’

  “I’d realized the thing would take hours to get to that distant planet, traveling at the speed of light, even if it had been correctly aligned. But the machinery that should have done that through the years probably had long since failed for lack of power.

  “But I stood there till the groaning motors ceased altogether, and the screen was as dark as I’d found it, the signal light black. I released the stud then, and backed away, dazed by the utter collapse of an insane hope. Experimentally, I pressed the Neptune symbol again. So little power was left now, that only the faintest wash of murky light projected the Neptune image, little energy as that would have consumed.

  “I went out. Bitter. Hopeless. Earth’s last picture was long, long since painted—and mine had been the hand that spent Earth’s last poor resource. To its utter exhaustion, the eternal city had strived to serve the race that created it, and I, from the dawn of time had, at the end of time, drained its last poor atom of life. The thing was a thing done.

  “Slowly I went back to the roof and the dying suns. Up the miles of winding ramp that climbed a half mile straight up. I went slowly—only life knows haste—and I was of the dead.

  “I found a bench up there—a carved bench of metal in the midst of a riot of colorful, frozen towers. I sat down, and looked out across the frozen city to the frozen world beyond, and the freezing red Sun.

  “I do not know how long I sat there. And then something whispered in my mind: ‘We sought you at the television machine.’ I leaped from the bench and stared wildly about me.

  “It was floating in the air—a shining dirigible of metal, ruby-red in that light, twenty feet long, perhaps ten in diameter, bright, warm orange light gleamed from its ports. I stared at it in amazement.

  “ ‘It—it worked!’ I gasped.

  “ ‘The beam carried barely enough energy to energize the amplifiers when it reached Neptune, however,’ replied the creature in the machine.

  “I couldn’t see him—I knew I wasn’t hearing him, but somehow that didn’t surprise me.

  “ ‘Your oxygen has almost entirely given out, and I believe your mind is suffering from lack of oxygen. I would suggest you enter the lock; there is air in here.’

  “I don’t know how he knew, but the gauges confirmed his statement. The oxygen was pretty nearly gone. I had perhaps another hour’s supply if I opened the valves wide—but it was a most uncomfortably near thing, even so.

  “I got in. I was beaming, joyous. There was life. This universe was not so dead as I had supposed. Not on Earth, perhaps, but only because they did not choose! They had space ships! Eagerly I climbed in, a strange thrill running through my body as I crossed the threshold of the lock. The door closed behind me with a soft shush on its soft gaskets, locked, and a pump whined somewhere for a moment; then the inner door opened. I stepped in—and instantly turned off my alcohol burners. There was heat—heat and light and air!

  “In a moment I had the outer lacings loose, and the inner zipper down. Thirty seconds later I stepped out of the suit, and took a deep breath. The air was clean and sweet and warm, invigorating, fresh-smelling, as though it had blown over miles of green, Sun-warmed fields. It smelled alive, and young.

  “Then I looked for the man who had come for me. There was none. In the nose of the ship, by the controls, floated a four-foot globe of metal, softly glowing with a warm, golden light. The light pulsed slowly or swiftly with the rhythm of his thoughts, and I knew that this was the one who had spoken to me.

  “ ‘You had expected a human?’ he thought to me. ‘There are no more. There have been none for a time I cannot express in your mind. Ah, yes, you have a mathematical means of expression, but no understanding of that time, so it is useless. But the last of humanity was allowed to end before the Sun changed from the original G-O stage—a very, very long time ago.’

  “I looked at him and wondered. Where was he from? Who—what—what manner of thing? Was it an armor encased living creature or another of the perfect machines?

  “I felt him watching my mind operate, pulsing softly in his golden light. And suddenly I thought to look out of the ports. The dim red suns were wheeling across those ports at an unbelievable rate. Earth was long since gone. As I looked, a dim, incredibly dim, red disk suddenly appeared, expanded—and I looked in awe at Neptune.

  “The planet was scarcely visible when we were already within a dozen millions of mile
s. It was a jeweled world. Cities—the great, perfect cities—still glowed. They glowed in soft, golden light above, and below, the harsher, brighter blue of mercury vapor lighted them.

  “He was speaking again. ‘We are machines—the ultimate development of man’s machines. Man was almost gone when we came.’

  “ ‘With what we have learned in the uncounted dusty megayears since, we might have been able to save him. We could not then. It was better, wiser, that man end than that he sink down so low as he must, eventually. Evolution is the rise under pressure. Devolution is the gradual sinking that comes when there is no pressure—and there is no end to it. Life vanished from this system—a dusty infinity I cannot sort in my memory—my type memory, truly, for I have complete all the memories of those that went before me that I replace. But my memory cannot stretch back to that time you think of—a time when the constellations—

  “ ‘It is useless to try. Those memories are buried under others, and those still buried under the weight of a billion centuries.

  “ ‘We enter’—he named a city; I cannot reproduce that name—‘now. You must return to Earth, though, in some seven and a quarter of your days, for the magnetic axis stretches back in collapsing field strains. I will be able to inject you into it, I believe.’

  “So I entered that city, the living city of machines, that had been when time and the universe were young.

  “I did not know then that, when all this universe had dissolved away, when the last sun was black and cold, scattered dust in a fragment of a scattered universe, this planet with its machine cities would go on—a last speck of warm light in a long-dead universe. I did not know then.

  “ ‘You still wonder that we let man die out?’ asked the machine. ‘It was best. In another brief million years he would have lost his high estate. It was best.’
