As I groped ahead a second time I felt quite confident of my correctness, and diverged to the left at a junction I was sure I remembered. The spiralling continued, and I was careful not to stray into any intersecting passages. Soon, however, I saw to my disgust that I was passing the body at a considerable distance; this passage evidently reached the outer wall at a point much beyond it. In the hope that another exit might exist in the half of the wall I had not yet explored, I pressed forward for several paces, but eventually came once more to a solid barrier. Clearly, the plan of the building was even more complicated than I had thought.
I now debated whether to return to the centre again or whether to try some of the lateral corridors extending toward the body. If I chose this second alternative, I would run the risk of breaking my mental pattern of where I was; hence I had better not attempt it unless I could think of some way of leaving a visible trail behind me. Just how to leave a trail would be quite a problem, and I ransacked my mind for a solution. There seemed to be nothing about my person which could leave a mark on anything, nor any material which I could scatter - or minutely subdivide and scatter.
My pen had no effect on the invisible wall, and I could not lay a trail of my precious food tablets. Even had I been willing to spare the latter, there would not have been even nearly enough - besides which the small pellets would have instantly sunk from sight in the thin mud. I searched my pockets for an old-fashioned note-book - often used unofficially on Venus despite the quick rotting-rate of paper in the planet's atmosphere - whose pages I could tear up and scatter, but could find none. It was obviously impossible to tear the tough, thin metal of this revolving decay-proof record scroll, nor did my clothing offer any possibilities. In Venus's peculiar atmosphere I could not safely spare my stout leather suit, and underwear had been eliminated because of the climate.
I tried to smear mud on the smooth, invisible walls after squeezing it as dry as possible, but found that it slipped from sight as quickly as did the height-testing handfuls I had previously thrown. Finally I drew out my knife and attempted to scratch a line on the glassy, phantom surface - something I could recognize with my hand, even though I would not have the advantage of seeing it from afar. It was useless, however, for the blade made not the slightest impression on the baffling, unknown material.
Frustrated in all attempts to blaze a trail, I again sought the round central chamber through memory. It seemed easier to act back to this room than to steer a definite, predetermined course away from it, and I had little difficulty in finding it anew. This time I listed on my record scroll every turn I made - drawing a crude hypothetical diagram of my route, and marking all diverging corridors. It was, of course, maddeningly slow work when everything had to be determined by touch, and the possibilities of error were infinite; but I believed it would pay in the long run. The long twilight of Venus was thick when I reached the central room, but I still had hopes of gaining the outside before dark. Comparing my fresh diagram with previous recollections, I believed I had located my original mistake, so once more set out confidently along the invisible hall-ways. I veered further to the left than during my previous attempts, and tried to keep track of my turnings on the records scroll in case I was still mistaken. In the gathering dusk I could see the dim line of the corpse, now the centre of a loathsome cloud of farnoth-flies. Before long, no doubt, the mud-dwelling sificlighs would be oozing in from the plain to complete the ghastly work. Approaching the body with some reluctance I was preparing to step past it when a sudden collision with a wall told me I was again astray. I now realized plainly that I was lost. The complications of this building were too much for offhand solution, and I would probably have to do some careful checking before I could hope to emerge. Still, I was eager to get to dry ground before total darkness set in; hence I returned once more to the centre and began a rather aimless series of trials and errors - making notes by the light of my electric lamp. When I used this device I noticed with interest that it produced no reflection - not even the faintest glistening - in the transparent walls around me. I was, however, prepared for this; since the sun had at no time formed a gleaming image in the strange material.
I was still groping about when the dusk became total. A heavy mist obscured most of the stars and planets, but the earth was plainly visible as a glowing, bluish-green point in the southeast. It was just past opposition, and would have been a glorious sight in a telescope. I could even make out the moon beside it whenever the vapours momentarily thinned. It was now impossible to see the corpse - my only landmark - so I blundered back to the central chamber after a few false turns. After all, I would have to give up hope of sleeping on dry ground. Nothing could be done till daylight, and I might as well make the best of it here. Lying down in the mud would not be pleasant, but in my leather suit it could be done. On former expeditions I had slept under even worse conditions, and now sheer exhaustion would help to conquer repugnance.
So here I am, squatting in the slime of the central room and making these notes on my record scroll by the light of the electric lamp. There is something almost humorous in my strange, unprecedented plight. Lost in a building without doors - a building which I cannot see! I shall doubtless get out early in the morning, and ought to be back at Terra Nova with the crystal by late afternoon. It certainly is a beauty - with surprising lustre even in the feeble light of this lamp. I have just had it out examining it. Despite my fatigue, sleep is slow in coming, so I find myself writing at great length. I must stop now. Not much danger of being bothered by those cursed natives in this place. The thing I like least is the corpse - but fortunately my oxygen mask saves me from the worst effects. I am using the chlorate cubes very sparingly. Will take a couple of food tablets now and turn in. More later.
LATER - AFTERNOON, VI, 13
There has been more trouble than I expected. I am still in the building, and will have to work quickly and wisely if I expect to rest on dry ground tonight. It took me a long time to get to sleep, and I did not wake till almost noon today. As it was, I would have slept longer but for the glare of the sun through the haze. The corpse was a rather bad sight - wriggling with sificlighs, and with a cloud of farnoth-flies around it. Something had pushed the helmet away from the face, and it was better not to look at it. I was doubly glad of my oxygen mask when I thought of the situation.
At length I shook and brushed myself dry, took a couple of food tablets, and put a new potassium chlorate cube in the electrolyser of the mask. I am using these cubes slowly, but wish I had a larger supply. I felt much better after my sleep, and expected to get out of the building very shortly. Consulting the notes and sketches I had jotted down, I was impressed by the complexity of the hallways, and by the possibility that I had made a fundamental error. Of the six openings leading out of the central space, I had chosen a certain one as that by which I had entered - using a sighting-arrangement as a guide. When I stood just within the opening, the corpse fifty yards away was exactly in line with a particular lepidodendron in the far-off forest. Now it occurred to me that this sighting might not have been of sufficient accuracy - the distance of the corpse making its difference of direction in relation to the horizon comparatively slight when viewed from the openings next to that of my first ingress. Moreover, the tree did not differ as distinctly as it might from other lepidodendra on the horizon. Putting the matter to a test, I found to my chagrin that I could not be sure which of three openings was the right one. Had I traversed a different set of windings at each attempted exit? This time I would be sure. It struck me that despite the impossibility of trail-blazing there was one marker I could leave. Though I could not spare my suit, I could - because of my thick head of hair - spare my helmet; and this was large and light enough to remain visible above the thin mud. Accordingly I removed the roughly hemi-spherical device and laid it at the entrance of one of the corridors - the right-hand one of the three I must try.
I would follow this corridor on the assumption that it was correct; repeati
ng what I seemed to recall as the proper turns, and constantly consulting and making notes. If I did not get out, I would systematically exhaust all possible variations; and if these failed, I would proceed to cover the avenues extending from the next opening in the same way - continuing to the third opening if necessary. Sooner or later I could not avoid hitting the right path to the exit, but I must use patience. Even at worst, I could scarcely fail to reach the open plain in time for a dry night's sleep.
Immediate results were rather discouraging, though they helped me eliminate the right-hand opening in little more than an hour. Only a succession of blind alleys, each ending at a great distance from the corpse, seemed to branch from this hallway; and I saw very soon that it had not figured at all in the previous afternoon's wanderings. As before, however, I always found it relatively easy to grope back to the central chamber.
About 1 P.M. I shifted my helmet marker to the next opening and began to explore the hallways beyond it. At first I thought I recognized the turnings, but soon found myself in a wholly unfamiliar set of corridors. I could not get near the corpse, and this time seemed cut off from the central chamber as well, even though I thought I had recorded every move I made. There seemed to be tricky twists and crossings too subtle for me to capture in my crude diagrams, and I began to develop a kind of mixed anger and discouragement. While patience would of course win in the end, I saw that my searching would have to be minute, tireless and long-continued.
Two o'clock found me still wandering vainly through strange corridors - constantly feeling my way, looking alternately at my helmet and at the corpse, and jotting data on my scroll with decreasing confidence. I cursed the stupidity and idle curiosity which had drawn me into this tangle of unseen walls - reflecting that if I had let the thing alone and headed back as soon as I had taken the crystal from the body, I would even now be safe at Terra Nova.
Suddenly it occurred to me that I might be able to tunnel under the invisible walls with my knife, and thus effect a short cut to the outside - or to some outward-leading corridor. I had no means of knowing how deep the building's foundations were, but the omnipresent mud argued the absence of any floor save the earth. Facing the distant and increasingly horrible corpse, I began a course of feverish digging with the broad, sharp blade.
There was about six inches of semi-liquid mud, below which the density of the soil increased sharply. This lower soil seemed to be of a different colour - a greyish clay rather like the formations near Venus's north pole. As I continued downward close to the unseen barrier I saw that the ground was getting harder and harder. Watery mud rushed into the excavation as fast as I removed the clay, but I reached through it and kept on working. If I could bore any kind of a passage beneath the wall, the mud would not stop my wriggling out.
About three feet down, however, the hardness of the soil halted my digging seriously. Its tenacity was beyond anything I had encountered before, even on this planet, and was linked with an anomalous heaviness. My knife had to split and chip the tightly packed clay, and the fragments I brought up were like solid stones or bits of 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.
