metal. Finally even this splitting and chipping became impossible, and I had to cease my work with no lower edge of wall in reach.
The hour-long attempt was a wasteful as well as futile one, for it used up great stores of my energy and forced me both to take an extra food tablet, and to put an additional chlorate cube in the oxygen mask. It has also brought a pause in the day's gropings, for I am still much too exhausted to walk. After cleaning my hands and arms of the worst of the mud I sat down to write these notes – leaning against an invisible wall and facing away from the corpse.
That body is simply a writhing mass of vermin now – the odour has begun to draw some of the slimy akmans from the far-off jungle. I notice that many of the efjeh-weeds on the plain are reaching out necrophagous feelers toward the thing; but I doubt if any are long enough to reach it. I wish some really carnivorous organisms like the skorahs would appear, for then they might scent me and wriggle a course through the building toward me. Things like that have an odd sense of direction. I could watch them as they came, and jot down their approximate route if they failed to form a continuous line. Even that would be a great help. When I met any the pistol would make short work of them.
But I can hardly hope for as much as that. Now that these notes are made I shall rest a while longer, and later will do some more groping. As soon as I get back to the central chamber – which ought to be fairly easy – I shall try the extreme left-hand opening. Perhaps I can get outside by dusk after all.
NIGHT – VI, 13
New trouble. My escape will be tremendously difficult, for there are elements I had not suspected. Another night here in the mud, and a fight on my hands tomorrow. I cut my rest short and was up and groping again by four o'clock. After about fifteen minutes I reached the central chamber and moved my helmet to mark the last of the three possible doorways. Starting through this opening, I seemed to find the going more familiar, but was brought up short less than five minutes by a sight that jolted me more than I can describe.
It was a group of four or five of those detestable man-lizards emerging from the forest far off across the plain. I could not see them distinctly at that distance, but thought they paused and turned toward the trees to gesticulate, after which they were joined by fully a dozen more. The augmented party now began to advance directly toward the invisible building, and as they approached I studied them carefully. I had never before had a close view of the things outside the steamy shadows of the jungle.
The resemblance to reptiles was perceptible, though I knew it was only an apparent one, since these beings have no point of contact with terrestrial life. When they drew nearer they seemed less truly reptilian – only the flat head and the green, slimy, frog-like skin carrying out the idea. They walked erect on their odd, thick stumps, and their suction-discs made curious noises in the mud. These were average specimens, about seven feet in height, and with four long, ropy pectoral tentacles. The motions of those tentacles – if the theories of Fogg, Ekberg, and Janat are right, which I formerly doubted but am now more ready to believe – indicate that the things were in animated conversation.
I drew my flame pistol and was ready for a hard fight. The odds were bad, but the weapon gave me a certain advantage. If the things knew this building they would come through it after me, and in this way would form a key to getting out; just as carnivorous skorahs might have done. That they would attack me seemed certain; for even though they could not see the crystal in my pouch, they could divine its presence through that special sense of theirs.
Yet, surprisingly enough, they did not attack me. Instead they scattered and formed a vast circle around me – at a distance which indicated that they were pressing close to the unseen wall. Standing there in a ring, the beings stared silently and inquisitively at me, waving their tentacles and sometimes nodding their heads and gesturing with their upper limbs. After a while I saw others issue from the forest, and these advanced and joined the curious crowd. Those near the corpse looked briefly at it but made no move to disturb it. It was a horrible sight, yet the man-lizards seemed quite unconcerned. Now and then one of them would brush away the farnoth- flies with its limbs or tentacles, or crush a wriggling sificligh or akman, or an out-reaching efjeh-weed, with the suction discs on its stumps.
Staring back at these grotesque and unexpected intruders, and wondering uneasily why they did not attack me at once, I lost for the time being the will-power and nervous energy to continue my search for a way out. Instead I leaned limply against the invisible wall of the passage where I stood, letting my wonder merge gradually into a chain of the wildest speculations. A hundred mysteries which had previously baffled me seemed all at once to take on a new and sinister significance, and I trembled with an acute fear unlike anything I had experienced before.
I believed I knew why these repulsive beings were hovering expectantly around me. I believed, too, that I had the secret of the transparent structure at last. The alluring crystal which I had seized, the body of the man who had seized it before me – all these things began to acquire a dark and threatening meaning.
It was no common series of mischances which had made me lose my way in this roofless, unseen tangle of corridors. Far from it. Beyond doubt, the place was a genuine maze – a labyrinth deliberately built by these hellish things whose craft and mentality I had so badly underestimated. Might I not have suspected this before, knowing of their uncanny architectural skill? The purpose was all too plain. It was a trap – a trap set to catch human beings, and with the crystal spheroid as bait. These reptilian things, in their war on the takers of crystals, had turned to strategy and were using our own cupidity against us.
Dwight – if this rotting corpse were indeed he – was a victim. He must have been trapped some time ago, and had failed to find his way out. Lack of water had doubtless maddened him, and perhaps he had run out of chlorate cubes as well. Probably his mask had not slipped accidentally after all. Suicide was a likelier thing. Rather than face a lingering death he had solved the issue by removing the mask deliberately and letting the lethal atmosphere do its work at once. The horrible irony of his fate lay in his position – only a few feet from the saving exit he had failed to find. One minute more of searching and he would have been safe.
And now I was trapped as he had been. Trapped, and with this circling herd of curious starers to mock at my predicament. The thought was maddening, and as it sank in I was seized with a sudden flash of panic which set me running aimlessly through the unseen hallways. For several moments I was essentially a maniac – stumbling, tripping, bruising myself on the invisible walls, and finally collapsing in the mud as a panting, lacerated heap of mindless, bleeding flesh.
The fall sobered me a bit, so that when I slowly struggled to my feet I could notice things and exercise my reason. The circling watchers were swaying their tentacles in an odd, irregular way suggestive of sly, alien laughter, and I shook my fist savagely at them as I rose. My gesture seemed to increase their hideous mirth – a few of them clumsily imitating it with their greenish upper limbs. Shamed into sense, I tried to collect my faculties and take stock of the situation.
After all, I was not as badly off as Dwight has been. Unlike him, I knew what the situation was – and forewarned is forearmed. I had proof that the exit was attainable in the end, and would not repeat his tragic act of impatient despair. The body – or skeleton, as it would soon be – was constantly before me as a guide to the sought – for aperture, and dogged patience would certainly take me to it if I worked long and intelligently enough.
I had, however, the disadvantage of being surrounded by these reptilian devils. Now that I realized the nature of the trap – whose invisible material argued a science and technology beyond anything on earth – I could no longer discount the mentality and resources of my enemies. Even with my flame-pistol I would have a bad time getting away – though boldness and quickness would doubtless see me through in the long run.
But first I must reach the exterior – unless I could lure or provoke some of the creatures to advance toward me. As I prepared my pistol for action and counted over my generous supply of ammunition it occurred to me to try the effect of its blasts on the invisible walls. Had I overlooked a feasible means of escape? There was no clue to the chemical composition of the transparent barrier, and conceivably it might be something which a tongue of fire could cut like cheese. Choosing a section facing the corpse, I carefully discharged the pistol at close range and felt with my knife where the blast had been aimed. Nothing was changed. I had seen the flame spread when it struck the surface, and now I realized that my hope had been vain. Only a long, tedious search for the exit would ever bring me to the outside.
So, swallowing another food tablet and putting another cube in the elecrolyser of my mask, I recommenced the long quest; retracing my steps to the central chamber and starting out anew. I constantly consulted my notes and sketches, and made fresh ones – taking one false turn after another, but staggering on in desperation till the
