Part 2

But my order had been unnecessary, for even as the half-dozen great cubes flashed away, our cruisers, still some eight hundred in number, had turned and were racing after them like unleashed hounds after their prey. Downward and backward we raced after them, low across the glowing surface of the great comet, over the deadly coma to where the faint, vast tail issued from it. Ahead we could see the six cubes fleeing onward, at a speed equal to our own, and the sight of them caused us to open to the last notch the power of our throbbing generators for that wild pursuit. Within moments, at that tremendous speed, there came into view ahead the rear rim of the coma's colossal glowing sphere, with the fainter glow that marked the currents of the great tail streaming back from the rim into the void of space.

Swift as were the great cubes ahead, though, our great cruisers of the Interstellar Patrol, speediest of all the galaxy's ships, were proving now to be swifter, since slowly, steadily, we had begun to overhaul those fleeing shapes. I heard Gor Han's deep voice, excited as always in battle, from the speech-instruments, heard Jurt Tul's calm comments as we drove nearer the flying cubes, heard Najus Nar's eager cries. The cubes were passing out now from over the great coma, on over the vast tail, to my puzzlement. I had thought they were striving to gain the interior of the comet, but instead they were racing away from it, while with every moment we were drawing nearer to them. Then, just when it seemed that another moment's flight would bring us upon them, they halted abruptly in space, hovering above the faint, vast-streaming tail, and then plunged straight down into the mighty currents of the tail, and were moving back, _inside_ that tail, toward the great coma behind us!

"The tail!" cried Najus Nar. "They're going up the tail itself and into the coma's heart!"

But I too had seen and had understood all in that moment, had understood what I had not dreamed before, that the only opening through the great coma to the hollow at its heart lay at the coma's rear, and could be reached only by struggling up to it through the awful currents of the tail! These mighty cubes, I saw, had been constructed in that shape especially to resist and endure those terrible, back-sweeping ether-currents set up by the comet's rush through the void, terrific currents glowing with the electrical energy shot backward and dissipated in driving the comet on. The cubes thus specially constructed could brave those colossal currents where weaker craft would be battered to fragments. All this I understood and weighed, in that tense moment, and then had made decision and was shouting back into the instrument before me.

"Down with our ships, too, then!" I cried. "_We're going up the tail after them!_"

I heard an exclamation from Gor Han, an answering shout from Najus Nar, and then my cruiser and all the cruisers behind us were dipping steeply downward, plunging into the vast and faint-glowing tail! The next moment was one of blind, utter confusion, for as we plunged into the terrific currents our cruisers were whirled up and backward as though by gigantic hands, thrown helplessly like leaves in a terrific wind, cruiser smashing against cruiser and destroying each other there by dozens in that wild moment. Then as the pilot beside me clung to the controls, bringing its bows around to face those mighty currents, heading toward the coma, our ship steadied, while those about it steadied likewise. We had lost half a hundred ships in that first terrific plunge, but neither my own nor those of the three Sub-Chiefs had been injured, and now we were moving slowly up the great currents of the tail toward the coma. The tail about us was to the eyes but a great region of faint light, but far ahead of us there glowed like a crimson wall of light across the heavens the mighty coma, and against it we could make out the dark square shapes of the cube-ships we pursued, likewise fighting their way toward the coma through those terrific currents.

* * * * *

I think now that the moments which followed, as we struggled in pursuit of those cubes, were almost the most terrible I ever experienced, moments in which it seemed impossible that our ships could breast such awful currents and live. About us the currents roared deafeningly, thrilling through every portion of our ships, sweeping against us with titanic power. On and on we struggled, veering to take advantage of weaker currents, blundering into great maelstroms, swaying, plunging, fighting on, with the coma's glowing wall looming ever closer ahead. I heard Gor Han's anxious comments from the instrument before me, glimpsed cruisers here and there behind my own collapsing and sweeping backward, knew that not for long could we fight against those currents and live.

The coma was very near, now, a giant wall of crimson light across the heavens, and now I made out a dark circle within that glowing wall, a circular opening rapidly largening to our eyes and toward which the flying cubes ahead were struggling.

"The opening!" Gor Han was shouting, his voice coming to me even above the awful din of the currents about us.

"Straight toward it after those cubes!" I cried. "Our ships can't stand this much longer!"

Now ahead I could see the cube-ships we pursued struggling toward that opening slower and slower, fighting the currents which were most powerful here where they issued from the mighty coma ahead. A moment more, though, and they had reached it, and vanished inside, while we in turn were fighting through the titanic sweep of those currents toward it. On--on--the currents that raged against us had become awful in strength, seeming to clutch at us with supreme power at this last moment. The opening loomed larger ahead, now, a dark circular passageway remaining miraculously open and unchanged through that electrical sea whose deadly crimson mass formed its walls. On--on--it seemed that never could we reach it, so terribly did the currents sweep about us. Yard by yard, foot by foot, we crept forward toward it, were on its brink, seemed to hesitate there for an instant before being swept backward and away, and then with a supreme last effort of our throbbing generators we crept forward out of the grip of those gigantic currents and into the open passageway!

Now all about us there raged the glowing electrical sea of the colossal coma, into the deadly mass of which the passage led, a straight passage which I knew could only be artificially made and maintained. Far ahead in that light-walled passage we could glimpse the dark shapes of the cubes, fleeing still before us, and now with humming generators our cruisers leapt forward, through that tunnel of the deadly coma! Above, below, on each side, there raged the coma's electrical sea, which it were annihilation to touch, and the circular passage down which we fled was hardly wide enough to admit three of our ships abreast, yet down it at reckless speed we sped, all thought leaving us now save the wild excitement of the pursuit.

Crimson light from the hell of glowing death that raged all about us beat blood-like upon us as we drove on, yet the cries of Gor Han and Najus Nar and even the cool Jurt Tul mingled with my own from the speech-instrument, as we shot forward in pursuit of the fleeing cubes. Never, surely, was pursuit stranger than that one, the galaxy's hundreds of cruisers, manned by every dissimilar shape to be found upon its myriad worlds, leaping forward in the narrow opening that led through a comet's deadly mass into its unglimpsed heart, after the strange cube-craft that fled on before us. A single slip of the controls for a fraction of an inch was enough to send any cruiser into the incandescent walls to death, and indeed I glimpsed cruisers among those that followed me blundering into those walls in our wild flight onward and vanishing in wild spurts of light!

Yet on and on we leapt, and shouted now as we saw the cubes ahead shooting out from the passageway into open space beyond. A moment more and we were on their tracks, were flashing out too from the encircling crimson walls of glowing death, that vanished suddenly from about us as we entered into a vast region of open space, the immense open space that lay at the giant comet's heart! Far, far away from us there stretched the walls of the gigantic coma that encompassed this open space, above and below, enclosing all that space within their deadly electrical sea. This, though, we had expected and it was not this that held our attention in that stunning moment. It was the comet's nucleus, hanging at the center of that space. For that nucleus was a mass of smoothly revolving worlds!

Worlds! Worlds there at the comet's heart, worlds that were disk-shaped instead of spherical, a dozen or more of which revolved in a great ring about a single world that was larger than any of the others, and that hung motionless! Over those revolving worlds, down toward that central disk-world the cube-ships ahead of us were fleeing, and as we shot down after them I saw that it and the rim of other disks, though not illuminated by the dusky crimson glow of the encompassing comet, were bathed in light, pure white light that seemed to emanate from themselves! And as we rushed down toward the surface of that central world I glimpsed upon it smooth dark ways and streets, on each side of which were what seemed great, smooth-sided shallow pits; glimpsed multitudes of dark, shapeless figures that moved to and fro along those streets and ways, tending great mechanisms set up in masses here and there along them; glimpsed a single great circular plaza or smooth-floored clearing set amid those streets and pits and massed mechanisms, at the center of which loomed a great, truncated dark pyramid upon whose flat summit rested some big disk-shaped mechanism. Then in that same flashing glimpse I saw that which drove all else from my mind, saw from the surface of all this mighty world a tremendous swarm of great cube-ships that was driving up toward the ships we pursued, and toward ourselves!

"Cube-ships!" Gor Han was crying. "Cube-ships in thousands, and they're attacking us!"

"Back!" I cried. "Back up and outward! We have no chance against these thousands!"

But before our cruisers could turn, before we could halt and slant back upward, the thousands of leaping cubes from beneath were upon us! Then about us for a wild moment was conflict indescribable, colossal cubes rushing by thousands upon our hundreds of gleaming cruisers, crimson electrical bolts and black force-beams whirling and stabbing in wild destruction. Cubes thronged thick about us as our cruiser leapt upward, and then the thrumming of the force-beams of our ship sounded as they drove paths of instant devastation through the ruck of battle about us. From the speech-instrument there came above the din of battle a wild cry from Gor Han, and I saw that a crimson bolt had grazed past his cruiser's stern, warping its whole side with its terrific power and sending his craft swirling helplessly down to the world below! I cried out at that sight, then saw Najus Nar's craft slant downward even as my own struggled wildly with the cubes about it, saw the insect-man's cruiser drive right and left with force-beams, as other cubes from beneath rushed up toward it. Then as it shot downward among them to reach Gor Han's falling ship it had crashed glancingly along the side of one of the uprushing cubes, and with its prow a twisted wreck of metal was whirling down also!

"Gor Han! Najus Nar!" I shouted, as I saw them fall; then a deadly bolt of blinding crimson fire flashed past our cruiser's walls, missing us only by inches; I yelled crazily as the cube above that had loosed it was driven smashingly into the battle whirl about us by our swift-leaping force-beam. But about us now our cruisers were swiftly vanishing, as the hordes of cube-ships rushed upon them! They were stabbing out with black beams to the bitter end, driving cubes down to death with those beams, yet they were fast disappearing beneath the withering hail of deadly crimson electrical bolts. But a score of cruisers remained beside me, now but a dozen, as the crimson bolts still flashed thick, Jurt Tul's ship fighting side by side with my own. Then, as but a scant five or six cruisers remained, the target of all the blasting bolts from the massed cubes about us, there penetrated through the deafening roar of battle from the speech-instrument Jurt Tul's great voice.

"Back out of the comet!" he yelled. "It's our only chance, Khel Ken--to get outside until the rest of the Patrol's cruisers arrive!"

I saw, even through my mad blood-lust at that moment, that he was right and that our only chance of further action lay in winning clear of the comet. "Back, then!" I cried.

With the words our half-dozen cruisers zoomed upward and outward at such tremendous velocity that the deadly bolts from the thousands of cubes beneath fell short of us in our wild upward rush. Up--up--upward from that great central world we shot, and outward. The cube-ships beneath, taken by surprize for the moment, then massed also and leapt up after us. And now, a scant six cruisers remaining of all the thousands that had been our force a few minutes before, we raced out from that central world, toward the darker circle in the distant coma's wall that was the one passage to outside space. Out over the ring of revolving disk-worlds we shot, out toward that opening, out----

But what was that? That swarm of tiny, square shapes, of gleaming little cube-shapes, which even at that distance we could see had darted suddenly from one side across the dark circle of the single opening? Close-massed in a compact swarm, they had shot out from the side to halt _across_ that opening, hanging motionless there. Cube-ships, hundreds in number, that had flashed toward that opening from one side, to hang motionless there across it, while behind us there raced after us in deadly pursuit the other cube-ship thousands! Cube-ships that hung motionless, ready, across that round opening through the great coma, and at sight of which I cried aloud once more.

"They've cut us off--they're ahead of us!" I cried. "_They've barred the one way to outside space and we're trapped here at the comet's heart!_"

The moment that followed, as our ships slowed and hung motionless, with doom ahead and doom behind, was one in which the death that we had dared a score of times since reaching the comet loomed full before us. The cube-ships that barred the way ahead, the thousands racing toward us from behind--these were like death's great jaws closing upon us, and for an instant I felt myself surrendering to utter despair. But then, as my eyes dropped downward, toward the ring of outer smaller disk-worlds over which we had been flashing and above which we now hung, a flicker of hope shot through me and I turned swiftly to the speech-instrument.

"Down to those worlds below!" I cried. "There's a chance that we can hide on one of them until we can get out of the comet!"

Instantly, spurred to greater swiftness by our desperate situation, our half-dozen cruisers were slanting sharply down toward one of those revolving disk-worlds. The surface of that world leapt up with terrific speed toward us as we shot recklessly downward, and I sighted cities of pits and streets and mechanisms like that of the central world upon it, cities though that did not cover all its surface as in the central world, but were scattered about it, the rest of the disk-world's surface being a tumbled mass of mighty mountains and chasmed valleys, all of barren dark rock. It was down toward one of these tremendous chasms, near the disk-world's outer edge, that we were heading, every feature of that world's surface lying plain beneath us in the strange white light that bathed all these revolving worlds. Downward into that awful chasm our cruisers shot, and as they did so I glimpsed, high above, a swarm of tiny dark cube-shapes that had halted their pursuit of us, were circling about and dropping lower as though to discover our whereabouts!

Our lives depended on finding some place of hiding in this tremendous-walled chasm, I knew, and as we arrowed down into its depths, white-lit by the same strange illumination, I gazed swiftly about for some place of concealment. A moment the search seemed hopeless, there being nothing but the chasm's narrow floor of barren rock, its towering jagged rock sides, and then as we shot along its length I sighted a great crack or crevice in one of them, a long, crack-like opening that was large enough to admit our cruisers, and behind which could be glimpsed the dark depths of some great cavernous hollow in the rock.

"Through that crack!" I ordered swiftly, saw Jurt Tul's cruiser move quickly toward it, scraping against the crack's jagged edges as it pushed through into the dark cavern behind. Another of our cruisers followed, and then the rest, one by one, until my own was scraping inside, just as I saw the cube-ships high above dropping toward us, splitting into divisions of a dozen ships each which were slanting down over all the surface of this world in search of us, one of them heading straight toward the great chasm!

As it slanted down toward us I gazed about me, saw that our six cruisers were hanging in a dark, cavernous abyss that seemed to extend far down into the depths of this disk-world. A rocky shelf just inside the crack-opening, though, seemed large enough for us to rest our ships upon; so instantly we brought them to rest there, cutting off the generators whose humming might betray us. Then, as our space-doors opened with a slight inward hiss from the higher-pressure air of the disk's atmosphere, I stepped quickly out, found Jurt Tul and the other cruiser captains beside me, and then we had all suddenly crouched down inside the great crack's edge as a score of the great cube-ships shot down into the white-lit chasm outside.

Peering out from the cavern's dark depths we saw those cubes hanging there, then moving slowly along the chasm's length as though in search of us. Down its length they disappeared and we breathed easier for a moment; then they reappeared, coming to rest on the chasm's floor directly beneath the opening in which we crouched, scarce a half-hundred feet below us. Tensely we watched, saw that doors were opening in those cubes' sides, creatures emerging, the comet-creatures of these strange worlds. And at sight of those creatures even our tense situation could not suppress our gasps. For they were--liquid-creatures! Creatures whose bodies were liquid instead of solid, creatures that were each but a pool of thick black liquid, flowing viscously about, in each of which pools floated two round, white blank disks, great white pupilless eyes.

We saw them flowing forth from out their cubes, saw some whose viscous bodies held what seemed tools or weapons, saw the floating eyes turned this way and that about the chasm, as though in search of us. Then a score of the strange creatures did an incomprehensible thing: they flowed together into a single liquid mass, a great black pool in which floated all their eyes, their liquid bodies mingling together! A moment they remained thus, then had separated, each from the others, and were returning to their cubes.

"Conversing!" whispered Jurt Tul beside me. "It's their method of conversing, of exchanging thoughts--to mingle their liquid bodies one with another!"

I knew the amphibian was right, and shuddered involuntarily at the thing we had seen. The cubes' doors had closed now, and the cubes were lifting upward from the chasm's floor. One, more suspicious apparently than the rest, hovered a moment outside the crack within which we crouched, and we shrank back, suddenly tense, but after a moment's inspection it too had driven up after the others, which passed from sight high above, searching slowly across the disk-world's surface in a strange formation as though following some discussed plan. We breathed easier, then, standing erect, and I turned quickly to Jurt Tul.

"Our only chance is to get out of the comet and wait for the five thousand Patrol cruisers that were to come after us," I told him. "But we can't leave the comet with Gor Han and Najus Nar prisoned in it!"

The great amphibian shook his head. "We could venture back to the comet-city on the central world to attempt to find them," he said, "but in this brilliant white light we'd be seen and destroyed at once."

I was silent, for I knew that it was so, and broodingly I considered that light, whose white illumination filled all the great chasm outside, beating faintly even into the cavern, yet seeming to have no visible source whatever. And then, even as I gazed upon it, that light died! It seemed to gray, to darken, and then had vanished altogether, within a moment, while at the same moment there beat faintly through the air from far away a great clanging note like that of a giant gong. The chasm outside, the world and worlds about us, lay now in dusk, their only illumination the lurid, dark crimson light of the comet's glowing coma, a red disk that gave to the barren rocky world about us an inconceivably weird appearance.

"That gong!" Jurt Tul was saying. "You heard it? It sounded when the light died--it means that these comet-creatures maintain and regulate their own day and night!"

"That white light," I said; "you mean that it's made by them, turned off for their night?"

He nodded quickly. "It must be. They can use the coma's great electrical energy to produce that light at will, just as they use that energy for their crimson bolts. They must turn it off and on at regular intervals, to produce their day and night, their activity-periods and rest-periods."

"But then we can venture back to the comet-city--back to the central world for Gor Han and Najus Nar!" I exclaimed, and he nodded.

"Yes, but we'd best wait longer, since now the cube-ships' search will be going on, even in this dusk, and we'd have small chance of escaping them."
