structure whose surface was covered with other models and with white sheets of stiff cloth or paper covered with drawings and designs, and behind this sat another of the globe-men, a little larger than any we had yet seen. As we halted before him he inspected us for a moment with his large, unwinking eyes, then spoke in deep, thrumming inflections to our two guards. The latter answered him at length, and again he considered us.
During the moments that we stood there I had noted that Sarto Sen, beside me, seemed intensely interested in the models and design-covered sheets which lay on the desk before us. Now, as the creature behind the desk seemed to pause, my friend moved forward and picked up one of the sheets, and a metal pencil which lay beside it. In a moment he was drawing on the sheet some design which I could not see, and this done he handed it to the monster behind the desk. The latter reached for it, inspected it closely, and then raised his eyes to Sarto Sen with something of surprise apparent even on his unhuman features. He uttered a short command, then, and instantly one of the two guards motioned Sarto Sen aside, while the other herded Hal Kur, Nar Lon and me again toward the door. As we passed out of the room I glanced back and saw Sarto Sen, still under the watchful eyes of his guard, bending over the desk, intensely interested, sketching another design.
Again we were in the anteroom, in which there lounged still the guard of armed globe-men. Instead of returning to the corridor through which we had come, though, we were conducted through a door on the room's opposite side, and passed down a similar long hall, halted at last by our guard before a low door in its side. This he flung open, motioning us to enter, and as the death-dealing disk in his grasp was trained full upon us we had no choice but to obey, and passed into a square, solid-walled little room which was but half-lit by a few loopholes in one of its sides. Behind us the door slammed shut, its strong bolts closing with a loud grating of metal. We were prisoners-prisoners on the planet of a distant star.
And now, looking back, it seems to me that the days of imprisonment which followed were the most terrible I have ever known. Action, no matter of what sort, gives surcease at least from mental agony, and it was agony which we suffered there in our little cell. For with the passing of every day, every hour, the crimson sun above was drawing nearer toward our own by millions of miles. And we, who alone had power to find the cause of the red sun's deflection- we lay imprisoned there in the city of the globe-men, watching doom creep upon our universe.
Hour followed hour and day followed day, remorselessly, while we lay there, hours and days which we could measure only by the steady circling of the sunlight that slanted through our tiny windows. With each night came cold, a bitter cold that penetrated to our bones, and for all the red splendor of the dying sun above, the days were far from warm. Twice each day the door opened and a guard cautiously thrust in our food, which consisted of a mushy mixture of cooked vegetables and a bottle of red-tinged, mineral-tasting water.
We spoke but little among ourselves, except to wonder as to the whereabouts of Sarto Sen. We had heard nothing of him since we had left him and could not know even whether our friend was alive or dead. What our own fate was to be we could not guess, nor, in fact, was even that of much interest to us. A few months longer and we would meet death with all on this planet, when Alto and our own sun crashed together. Whether or not we lived until then was hardly a great matter.
Then, ten days after our capture, there came the first break in the monotony of our imprisonment. There was a rattle of bolts at our door; it swung open, and Sarto Sen stepped inside. As the guards outside closed the door my friend sprang toward me, his face eager.
'You're all right, Jan Tor?' he exclaimed quickly. 'They told me you were unharmed, but I worried-'
A phrase in his speech struck me. 'They told you?' I repeated. 'They?'
He nodded, his eyes holding mine. 'The globe-men,' he said simply.
We stared at him, and he stepped swiftly to the door, tried it and found it fast, then came back and sat down beside us.
'The globe-men,' he repeated solemnly, 'those children of Alto, those creatures of hell, who have turned their parent sun from its course to send it crashing into our own, to wipe out our universe.'
At our exclamations of stunned surprise he was silent, musing, his eyes seeming to gaze out through somber vistas of horror invisible to us. When he spoke again it was slowly, broodingly, as though he had forgotten our presence.
'I have found what we came here to learn,' he was saying; 'have discovered the reason for the deflection of this star. Yet even before, I guessed… If a star had planets and those planets inhabitants-inhabitants of supreme science, supreme power-would they not use that science and that power to save themselves from death, even though it means death for another universe? And that is what they have done, and what I suspected before.
'It was that suspicion that stood me in good stead when we were examined there by the chief of the globe- men. I had glimpsed on his desk sheets with astronomical designs on them, and so I took a sheet myself and drew on it a simple design which he understood immediately, a design which represented two suns colliding. It convinced him of my knowledge, my intelligence, so that when he sent the rest of you to this cell he retained me for questioning. And for hours afterward I drew other sketches, other designs, while with gestures he interrogated me concerning them. It was slow, fumbling communication, but it was communication, and gradually we perfected a system of signs and drawings by which we were able to exchange ideas. And through the succeeding days our sign-communication continued.
'I informed him, in this way, that we were visitors from another star, but I was too cautious to let him know that we were children of the sun into which Alto was soon to crash. Instead I named Sirius as our native star, explaining that we had come from there in our vibration-cruiser for purposes of exploration. It was the cruiser which interested him most, evidently. The scientists of the globe-people had been examining it, he told me, and he now asked me innumerable questions concerning its design and operation. For though the globemen have gravity-screen ships, like our own old-fashioned ones, in which they can travel from planet to planet, they have no such star- cruisers as this one of ours. Hence his questions, which I evaded as well as I could, turning the subject to the coming collision of the two suns, which I stated had been foreseen by the astronomers of my own universe. And as I had expected, my news of the coming collision was no surprise to him. For, as he casually explained, that collision was being engineered in fact by his own people, the globe-men, for their own purposes.
'For ages, it seems these globe-men have dwelt on the planets of Alto. First they had inhabited the outermost planet, billions of miles from Alto itself, but which was yet warm enough for existence because of their sun's titanic size and immense heat. There they had risen to greatness, had built up their science and civilization to undreamed-of heights. But as the ages passed, that outermost world of theirs was growing colder and colder, since Alto, like all other suns, was slowly but steadily cooling, shrinking and dying, radiating less and less heat. At last there came a time when the planet of the globe-men was fast becoming too cold for existence there, and then their scientists stirred themselves to find a way out. Spurred on by necessity, they hit upon the invention of the gravity screen and with it constructed their first interplanetary space-ships. These they made in vast numbers, and in them the globe-people moved en masse to the next innermost planet, which still received enough heat from Alto to support life. There they settled, and there their civilization endured for further ages.
'But slowly, surely, their sun continued to cool and die, and with the terrible, machinelike inevitability of natural laws there came a day when again their world had grown too cold for their existence. This time, though, they had the remedy for their situation at hand, and again there took place a great migration from their cold planet to a warmer inner one. And so, as the ages passed, they escaped extinction by migrating from planet to planet, moving ever sunward as their sun waned in size and splendor, creeping closer and closer toward its dying fires.
'At last, though, after long ages, there drew down toward them the doom which they had averted for so long. Alto was still shrinking, cooling, and now they were settled upon its warmest, inmost planet, and had no warmer world to which to flee. But a short time longer, as they measured time, and their planet would become a frozen, lifeless world, for their sun would inevitably cool still further until it was one of the countless dark stars, dead and burned-out suns, which throng the heavens. It seemed, indeed, that this time there was to be no escape.
'But now there came forward a party among them which advanced a proposal of colossal proportions. They pointed out that Alto was moving steadily toward another sun, one much the same size as their own but flaming with heat and life, which it would pass closely within a short time. But if, instead of passing each other, the two suns should meet, should crash into each other, what then would be the result? It would be, of course, that the collision would form one new sun instead of the former two-one titanic, flaming sun whose heat would be sufficient to support life on any planet for countless ages. The inmost planets of Alto's system, and virtually all the planets of
