Ah, our Martian nights! A gorgeous spectacle that never ceases to enthrall the imagination of Barsoomians. How pale and bleak must seem the nights on earth, with a single satellite moving at a snail's pace through the sky at such a great distance from the planet that it must appear no larger than a platter. Even with the stress under which my mind was laboring, I still could thrill to the magnificent spectacle of this glorious night.

The distance that had required two days and nights of arduous efforts in coming from Morbus was spanned in a few hours by the swift malagor. It was with some difficulty that I forced the creature down upon the island from which we had set forth two days before, as it wished to land in its accustomed place before the gates of Morbus; but at last I succeeded, and it was with a sigh of relief that I slipped from the back of my unwilling mount.

It did not want to take off again; but I forced it to do so, as I could not afford to take the chance that it might be seen if it arose from the island after sunrise, and thus lead my enemies to my only sanctuary when their suspicions were aroused by the tale which I knew the returning searching party would have to tell.

After I had succeeded in chasing it away I went immediately to the mouth of the tunnel leading back to the laboratory building, where I removed enough debris to permit me to crawl through into the tunnel. Before doing so, I tore up a large bush and as I wormed myself backward through the aperture I drew the bush after me, in the hope that it would fill the hole and conceal the opening. Then I hurried through the long tunnel to 3-17.

It was with a feeling of great relief that I found my body still safe in its vault-like tomb. For a moment I stood looking down at it, and I think that with the exception of Janai I had never so longed to possess any other thing. My face and my body may have their faults, but by comparison with the grotesque monstrosity that my brain now directed, they were among the most beautiful things in the world; but there they lay, as lost to me as completely as though they had gone to the incinerator unless Ras Thavas should return.

Ras Thavas! John Carter! Where were they? Perhaps slain in Phundahl; perhaps long since killed by the Great Toonolian Marshes; perhaps the victims of some accident on their return journey to Helium, if they had succeeded in reaching John Carter's flier outside Phundahl. I had practically given up hope that they would return for me, because enough time had elapsed to permit John Carter to have made the trip to Helium and to have returned easily, long before this; yet hope would not die.

I realized that my plans from now on must depend upon the conditions which confronted me. My hope was that I might reach the palace of Ay-mad, undetected, and hide myself in the throne room until Janai was brought before him. I should then attempt to destroy Ay-mad, and if I succeeded, which I had no doubt but that I should, to fight my way with Janai toward liberty. That I should fail seemed quite probable; but at least I should have destroyed her worst enemy, and might even find sufficient following among the hormads, which were always discontented with their rulers, to promise some success in taking over the city and Island of Morbus. This was my dream; but it was doomed never to be realized.

I had been reckoning without consideration of Vat Room No. 4.

As I approached the door that opened into the corridor, I thought that I heard sounds beyond the heavy panels; so that it was with the utmost caution that I opened the doors gradually. As I did so, the sound came more plainly to my ears.

It was indescribable-a strange surging sound, unlike any other sound in the world, and blending with it were strange human voices mouthing unintelligibly.

Even before I looked out, I knew then what it was; and as I stepped into the corridor I saw at my right and not far from the door a billowing mass of slimy, human tissue creeping gradually toward me. Protruding from it were unrelated fragments of human anatomy-a hand, an entire leg, a foot, a lung, a heart, and here and there a horribly mouthing head. The heads screamed at me, and a hand tried to reach forth and clutch me; but I was well without their reach. Had I arrived an hour later, and opened that door, the whole horrid mass would have surged in upon me and the body of Vor Daj would have been lost forever.

The corridor to the left, leading to the ramp that led to the upper floors, was quite deserted. I realized that the mass in Vat Room No. 4 must have found entrance at the far end of the pits through some unguarded opening below the street level. Eventually it would fill every crevice and make its way up the ramp to the upper stories of the Laboratory Building.

What, I wondered, would be the end? Theoretically, it would never cease to grow and spread unless entirely destroyed. It would spread out of the City of Morbus and across the Great Toonolian Marshes. It would engulf cities; or failing to mount their walls, it would surround and isolate them, condemning their inhabitants to slow starvation. It would roll across the dead sea bottoms to the farmlands of Mars' great canals. Eventually it would cover the entire surface of the planet, destroying all other life. Conceivably, it might grow and grow through all eternity devouring and living upon itself. It was a hideous thing to contemplate, but it was not without probability. Ras Thavas himself had told me as much.

I hastened along the corridor toward the ramp, expecting that I would probably find no other abroad at this time of night, as the discipline and guarding of the laboratory building was extremely lax when left to the direction of the hormads, as it had been after I had been demoted; but to my chagrin and consternation I found the upper floors alive with warriors and officers. A veritable panic reigned, and to such an extent that no one paid any attention to me. The officers were trying to maintain some form of order and discipline; but they were failing signally in the face of the terror that was apparent everywhere. From snatches of conversation which I overheard, I learned that the mass from Vat Room No. 4 had entered the palace and that Ay-mad and his court were fleeing to another part of the island outside the city walls. I learned, too, that the mass was spreading through the avenues of the city, and the fear of the hormad warriors was that they would all be cut off from escape. Ay-mad had issued orders that they should remain and attempt to destroy the mass and prevent its further spread through the city. Some of the officers were halfheartedly attempting to enforce the order, but for the most part they were as anxious to flee as the common warriors themselves.

Suddenly one warrior raised his voice above the tumult and shouted to his fellows. "Why should we remain here to die, while Ay-mad escapes with his favorites? There is still one avenue open; come, follow me!"

That was enough. Like a huge wave, the hideous monsters swept the officers to one side, killing some and trampling others, as they bolted for the exit which led to the only avenue of escape left open to them. Nothing could withstand them, and I was carried along in the mad rush for safety.

It was just as well, for if Ay-mad was leaving the city, Janai would not be brought into it.

Once in the avenue, the congestion was relieved, and we moved along in a steady stream toward the outer gate; but the flight did not stop here, as the terrified hormads spread over the island in an attempt to get as far away from the city as possible; so I found myself standing almost alone in the open space before the city where the malagors landed and from which they took off in their flight. To this spot would the captors of Janai bring her; so here I would remain hoping that some fortunate circumstance might suggest a plan whereby I might rescue her from this city of horrors.
