Racing forward as they were, the serpent-creatures rushing upon us could only loose their death-beams at chance upon us, and it was that alone that saved us, the deadly rays going wide except for one that struck and annihilated two of our party in its wild whirling. Then, before they could loose the beams again upon us, we had rushed forward to meet them and were among them; while at the same moment I shouted hoarsely over my shoulder to Jhul Din, who with his three followers had reached now the open door of our ship, behind us, and who now had hesitated for an instant as he saw our new foes rush down upon us.

"Go on, Jhul Din!" I cried. "Get away in the ship-we'll hold them till you get clear-"

Then we were meeting the serpent-creatures before us, and the next few moments we seemed surrounded, weighed down, by a solid mass of writhing bodies at which we struck crazily with the last of our strength. Even as we struggled wildly, though, I heard above the shouts and hissing cries about me the clang of the ship's space-doors, the swift humming of its generators; then as I staggered clear of my opponents for a moment I saw the great craft, with Jhul Din at the controls in its pilot room, lifting suddenly from the clearing, slanting steeply upward at immense speed, vanishing almost instantly in the crimson sunlight above. I yelled with exultation at the sight, and then was pulled down once more by my opponents, held tightly with Korus Kan and the others, as with wild hissing cries the greater part of the serpent-creatures rushed to their ships.

A moment more and two score of their craft were shooting sharply upward in hot pursuit of Jhul Din and his fleeing ship. Held tightly by our serpent-captors, we waited with them the return of the pursuing ships. Would they catch the big Spican? Slowly the minutes dragged past, while in the gulf of space above us, we knew, Jhul Din and his three followers were racing, twisting, fighting against that remorseless pursuit that would track him by the space-charts. Then at last, after a wait that seemed eternities in length, the dark, long shapes of the ships that had pursued him drove down from above and landed beside us, their serpent-crews emerging, but without trace of Jhul Din or his ship. Whether he had met his end beneath their death-beams, we could not say nor guess.

I knew, though, that they would hardly have given up the pursuit unsuccessfully so soon, and it was with doubt and fear in my heart that I rose now in response to the motioned commands of our captors. Guarding us now with a score or more of death-beam tubes they marched us across the circle toward the street that opened from it, and then down that street's length, between the mighty structures of blue force on either side. Half-transparent as were those buildings of pale blue light, we could see in them all the various floors and levels, as though in buildings of blue glass, and on those levels great ranks of half-glimpsed mechanisms tended by moving, writhing throngs of serpent-beings. Other throngs of them moved about us in the narrow street, from building to building, passing and repassing around us as we marched along.

To these, though, and to the buildings about us we paid but small attention; for at the end of the narrow street down which we were marching there loomed a great blue-shining structure of the same vibration as the others, but which dwarfed them by its tremendous size. Its vast, terraced sides slanted up for level upon mighty level, and as we neared it we saw that the street itself ended in it, passing through the high, great doorway before us into the shining structure's interior. In and out of it were pouring hordes of the serpent-creatures, and into it we were marched by our guards, through the great hall inside and on through a succession of other corridors in which writhed serpent-throngs. Through the open doors of the rooms along those corridors, as we passed by them, I could see serpent-creatures grouped about low, desk-like platforms, could see massed rows of great mechanisms that seemed tabulating or recording machines of some sort, saw other great rooms filled with flexible metal rolls like those we had captured with our oval ship, great collections of written records, and realized that this huge building must hold within itself the central controlling government of all the races of the serpent-creatures, on this great central world and on the worlds that revolved about the few living suns in the universe about us.

Our captors halted us, at last, before a door heavily guarded by serpent-creatures with ray-tubes, and while one of our own guards passed through the door into the great rooms we could glimpse inside, the remainder kept close watch upon us. I sensed that our own fate was being decided in those rooms beside us, and a few moments later saw that my guess had been right, for there came out the serpent-creature who had gone in, giving to our guards brief hissing orders. At once they marched us onward, emerging again into the great central hall that ran through the vast, blue-shimmering building, and progressing with us down that great, crowded corridor, until they turned us sharply to the right, through a big open door into a mighty hall or room, the nature and purpose of which we could not grasp for the moment.

It was filled with great, transparent cases, ranged in long, regular rows, extending from flickering blue-light wall to wall of the vast hall. In those cases there were shapes and figures, rigid and unmoving, that had apparently once been living things, and that were of a strangeness inconceivable. In hundreds, in thousands, they were grouped there in the protecting cases, beasts and beings all but indescribable in appearance, so strange were they even to our eyes, which had seen all the countless forms of life of our own galaxy. There was, in a case near us, a vast flat thing of white flesh, disk-like and scores of feet in diameter, with a single staring eye at its center. In another case was a great, many-legged cylinder of flesh without discernible features whatever. In still another, just before us, a black, powerful-looking insect-shape that was apparently double-headed, with two sets of black, beady eyes. All down the great hall's length stretched the rows of cases, filled with beings of which the sight of some alone was a creeping horror, and as we gazed at that incredible collection of alien forms in amazement, its significance rushed upon me.

"It's a museum," I exclaimed. "A great collection of the living forms that have existed in this dying universe-preserved here for countless ages, perhaps, out of the past."

As I spoke, though, there were coming down toward us from the far end of the great hall two serpent-creatures who seemed the custodians of this strange collection. Our guards addressed to them a few hissing commands, and the two turned, seemed to survey the cases about them, while we stared in perplexity. Then one turned toward a niche inset in the wall, in which rested two transparent containers or tubes of liquid, one of bright red and the other of green, and a long, slender metal needle that was apparently a hypodermic of some sort. Thrusting the needle into the red liquid, the serpent-creature holding it advanced to the case nearest us, which contained only the double-headed insect-creature. He swung the side of the case open, and then, with a swift jab, inserted the needle in the body of the thing inside.

There was a moment of silence, and then, to our amazement and horror, the insect-thing moved, its eyes roving from side to side, its limbs twitching. The thing was alive! The two serpent-creatures stepped toward the case, as it came to life, holding death-beam tubes toward it and addressing it in hissing tones. Apparently it was of some intelligence, for in response to those orders it stepped outside the case, down the hall toward another case which was all but filled by other strange shapes. Into this it stepped, at the command of the two, and then the one with the needle filled it with the green fluid, and inserted this in turn into the thing's body. At once that body stiffened, ceased to move, the thing becoming as rigid and unlife-like in appearance as before, its eyes staring stonily ahead in all the appearance of death.

Horror filled me at the sight, horror that sickened me, for I saw now that the things about us, the countless strange shapes in these rows of cases, were all as alive and conscious as ourselves, their life and intelligence unharmed but their bodies thrown into a state of rigid suspended animation by the insertion of the green fluid into them, a fluid that must be like the poisons with which some insects are able to keep their captured prey alive and unmoving indefinitely, a fluid that suspended all animation instantly and that could only be neutralized by the injection of the opposing red fluid, though always the victim remained conscious and alive. Alive! These myriad alien shapes about us-rigid and motionless, yet living and conscious, living perhaps for ages in that living death-my brain reeled at the thought. I turned to Korus Kan, sick with horror, but then stopped short, stiffened. For now the serpent-creature grasping the metal needle and the tube of green fluid was coming toward us.

All the horror of the fate intended for us burst across my brain in one flash of awful comprehension, then, and a strangled cry broke from me. "They're going to keep us here too." I cried, pointing with trembling hand. "Keep us here as strange beings-in living death in this museum of strange beings."

* * *

A moment we stood, in horror-stricken silence, and then as the full awfulness of the thing reserved for us penetrated the brains of my companions they uttered a medley of hoarse shouts of rage and horror and as one leapt forward upon the serpent-creatures with the fluid-tubes and upon our guards.

I think that we expected no better than death in that moment, for the death-beam tubes of the guards were full upon us, but I think too that we all preferred a swift, clean death to the horror of living death that awaited us in this museum of hell. But the very motive that made us desire death prevented the guards from loosing it upon us, preferring to follow their orders and place us in the collection about us rather than annihilate us. For instead of loosing the rays, as we sprang, they, leapt to meet us, at the same time giving utterance to loud, hissing cries of alarm.

Our guards outnumbered us, and though we leapt upon them with all the energy of horror and despair, striving to wrest the death-tubes from their grasp, they coiled about and held us, while into the great hall from the big corridor outside there rushed in answer to their alarm other scores of serpent-creatures, leaping likewise upon us. Wearied as we were and outnumbered by five to one, our struggle, though fierce, was of short duration, and then we were held completely by the creatures about us, while toward us again came the two serpent-creatures with the metal needle and two liquid-tubes. First toward me they came, dipping the needle into the green liquid and then stabbing it into my arm.

I shrank deeply as the sharp needle pierced my skin, but the next moment ceased to shrink, as through me there ran a wave of cold, a flood of utter iciness that held me motionless, unable to move. No muscle of mine, down to the smallest, could I control, lying there staring straight ahead, unmoving, unwinking, unbreathing even. My lungs, my heart, my blood, all had stopped moving in the instant that the poison flooded through me, yet my brain was as clear or clearer than ever, coldly clear, as though attached to it was no body whatever. My senses, though, still functioned, and though all power of motion had left me I could still see and hear as clearly as ever. It was as though my brain had been suddenly lifted from the mass of flesh that was my body, and endowed with a strange, lifeless life of its own.

Now the guards rose from me, leaving me lying motionless and rigid, and turned toward Korus Kan, who was being held down by others. His metal body seemed to puzzle them for an instant, and then they solved the problem by injecting the needle of green fluid into the nerve-tissues at the edge of his eyes, from which it would spread instantly to the other living organs cased by his metal body. Another moment and he too lay like me, rigid and powerless to move, our eyes meeting in an unchanging, stony stare. Within minutes more the green fluid had been injected into the last of our score of followers, and we had all become but rigid living statues, our consciousness and senses alone unaffected. Then by the serpent-creatures we were set into the transparent case from which the double-headed insect-thing had been moved to make way for us, were placed in a sitting position with backs against the case's sides, and then it was closed and the guards passed out of the big hall, leaving in it only the two serpent-creatures who were its custodians.

Rigid, unmoving, unbreathing, yet with consciousness, mind and senses as clear as ever, living brains cased in bodies that were helpless and motionless, I think that no position of any in all time could have been more terrible than ours. Had consciousness been suspended also, with the powers of our bodies, the captivity we suffered would have been but a dreamless sleep, at least; but to allow our consciousness and intelligence to remain, our bodies severed from our control-that was a torture that surely none other could ever equal. Statue-like we sat there, while hour followed hour, gazing always in the same direction with unmoving and unwinking eyes. Certainly no wonder would it have been had we gone mad in the first hours of that ghastly, terrible imprisonment. As the hours, the days, dragged past, though, I bent all my mental efforts toward the keeping of my sanity, and though at times my brain reeled beneath our terrible predicament, I desperately forced my thoughts into other channels. From where I sat I could gaze out into the great corridor outside the room, and that at least gave me something moving to contemplate, as through it swept the never-ceasing hordes of the serpent-people, a rush of activity that dwindled never until the rising of the darkest of the three suns marked the coming of the night, the sleep-period of the serpent-people. The light of that darker sun was so far dimmer than that of the other two that as this world turned between the three one-third of each day was spent in a dusky red darkness, a strange night in which all activity in the vast serpent-city about us seemed to cease, only our room's two serpent-guards and some others here and there outside remaining alert, our two room-guards being replaced at the beginning of each night by two others who alternated with them in their duties.

It was these things alone, though, the coming of night and the changing of our guards, the cessation and recommencement of the activity in the corridor outside, the waning and waxing of the crimson light that fell through the great building's flickering blue vibration-walls, that alone marked for us the passage of time. Day was following day while we sat on there in living death, unmoving as stones, and I knew that with each day the great fleet of the serpent-creatures I had glimpsed in the clearing would be approaching nearer to completion, as would the colossal death-beam cone with which they meant to wipe out all the races of all the galaxy's worlds. And we, on whom had rested the one chance of our universe, had failed-we were prisoners. I could not believe that Jhul Din, with his two or three followers, had managed to get through the great vibration-wall about this universe and speed to the Andromeda universe for help. Our last hope was gone, and the last hope of our galaxy with it, prisoned as we were in the helpless flesh of our own bodies, from which there could be no escape, lacking even the power to destroy ourselves and end our endless torture.

* * *

The passing days became blurred and confused in my mind, as we sat on there, and I felt that my brain was beginning to give at last beneath the awful strain. Time still I could roughly measure, though, by the waning of activity in the corridor outside, by the darkening of the crimson light that slanted through the pale blue walls. I think that it was on the tenth day of our imprisonment that I watched that light darkening, as always, wondering for how many times I was to see it thus, for how many days, years, ages, we were to lie in this living death, in the serpent-creatures' museum. As I watched, the passing throngs in the corridor outside were thinning, disappearing, with the coming of the dusky night, and soon there was almost complete silence about us, only the low hissing of the two serpent-guards, near the room's door, as they conversed there, breaking the stillness. Then suddenly my brooding thoughts were broken into by sharp surprise as I glimpsed a big, stealthy shape that showed itself for a moment in the corridor outside, and then dodged swiftly back.

With a sudden flame of excitement leaping in me for the first time since our imprisonment, I gazed toward the door, eyes unmoving as always. A moment more and the dark, erect shape that I had glimpsed outside came slowly into view once more, peering around the door's edge at the two serpent-guards, who for the moment were turned away from it. Seeing this, the lurking shape came slowly into the room, through the door from the shadows of the corridor, and as it did so I saw it clearly, and well it was for me that I could not speak or surely I would have shouted aloud. For it was Jhul Din.

A great wave of hope flooded through my brain as I saw the big Spican move stealthily inside, a thick metal bar in his grasp, his eyes roving about the dusky-lit great room. Then, as they fell upon our own case, upon us sitting motionless, I saw him gasp. A moment he surveyed us, my eyes staring stonily straight into his own as we sat still rigid and unmoving, and then he had turned, was moving silently toward the two unsuspecting guards. Closer he crept toward them, while I watched in an agony of suspense, and then as he reached them, raised his great bar above his head, the two creatures, warned by some slight sound, whirled suddenly around and confronted him.

Instantly the death-tubes they held came up, but in the moment that they did so Jhul Din's bar had smashed down upon them in a great, crushing blow that laid both lifeless on the blue force-floor. Then the Spican sprang to our case, opening its side and lifting us out, seeking with rough restorative measures to revive us. Yet we lay as silent and rigid as ever, and I saw despair creep into his eyes, could have shouted to him in my agony of mind had not my muscles been as far-severed from my brain's control as ever. Then the Spican raised from his fruitless efforts, gazed despairingly about, until his eyes fell upon the niche in the wall that held the tubes of red and green fluid. With a leap he was upon them, bringing them and the needle back toward us.

A moment he studied them, in doubt, then inserted the needle in the green fluid and pierced my forearm with it. I could have screamed to him his mistake had I had power of speech, for the green fluid injected into me had no effect upon me whatever, since I lay already beneath its force. Seeing this he swiftly made trial of the red fluid, injecting this in the same manner into my body, and then, as he gazed anxiously down upon my rigid figure, I felt a sudden warmth flooding through me, and for the first time in all those days became aware of my body, felt muscles and limbs moving in answer to my will's commands, felt heart and breathing starting after their long cessation. Then I was staggering up to my feet, the Spican's great arm about me, reeling upward with muscles utterly strange and cramped after those days of living death.

"Jhul Din!" I cried, my voice strange to my own ears after that time of speechlessness, and he gripped my arm reassuringly.

"Steady, Dur Nal," he said. "You're out of that now, and we'll win clear of this hellish city yet."

As he spoke he was dropping to the floor, injecting swiftly into the bodies of the rest the red fluid, beginning with Korus Kan, and as he did so he explained to me swiftly how he and his three followers had managed to elude the ships that had pursued him by fleeing from them into a near-by cluster of dead and dying suns, and pretending to have perished by crashing into a great dark star, landing his ship upon its barren, burned-out surface and escaping the scrutiny of the pursuing ships, who returned in the belief that he and his ship had met annihilation. In that hiding-place, upon that black and airless and lightless star, he had remained for days, not daring to venture forth amid the swarms of serpent-ships that filled the space-lanes about him, yet resolved to return and ascertain our fate. When at last, days later, he had been able to venture out, back to this vast world and down upon it through the dusky night, he had boldly landed the ship where it would excite no suspicion, in the landing-circle from which he had first escaped in it. Then, leaving his little crew of three in it and stealing through the shadows of the silent streets toward the great central building where he hoped against hope to find some trace of us, he had made his way through the darkened corridors of the huge structure until he had stumbled upon the strange museum of the serpent-people where we were prisoned.

While he swiftly explained this to me Korus Kan and our followers were staggering up beside me as the injections of red fluid revived them, one by one, and I turned toward the door, then uttered a horror-stricken exclamation. For in the corridor outside a single serpent-creature faced us, attracted perhaps by the sound of our voices, its glassy eyes full upon us. Even in the instant that I saw it, before ever I could leap upon it, it had turned with incredible quickness and was flashing back down the corridor, farther into the great building, uttering as it did so a high, hissing cry. And in an instant that cry was taken up and re-echoed in all the great structure about us, by the roused serpent-creatures who were rushing in answer to it.

"The alarm!" I cried. "Out of the building and to the ship."

With lightning swiftness now Jhul Din was injecting in the last of our followers the restorative red fluid, and then as those last ones stumbled up into consciousness beside us, we raced toward the door, out into the corridor. There, abruptly, we stopped short, our last wild hopes of escape in that instant blasted. For less than a thousand feet down the great corridor from us, pouring out into it from every quarter of the vast building's interior in answer to the hissing cries of alarm, there was racing down upon us a great mass of hundreds upon hundreds of the writhing serpent-creatures.
