Tales of Terror and Mystery, Sir Arthur Conan Doyle [best ereader for manga txt] 📗

Could you strike it with some gigantic hammer it would boom like a drum, or possibly cave in altogether and expose some huge subterranean sea. A great sea there must surely be, for on all sides the streams run into the mountain itself, never to reappear. There are gaps everywhere amid the rocks, and when you pass through them you find yourself in great caverns, which wind down into the bowels of the earth. I have a small bicycle lamp, and it is a perpetual joy to me to carry it into these weird solitudes, and to see the wonderful silver and black effect when I throw its light upon the stalactites which drape the lofty roofs. Shut off the lamp, and you are in the blackest darkness. Turn it on, and it is a scene from the Arabian Nights.

But there is one of these strange openings in the earth which has a special interest, for it is the handiwork, not of nature, but of man. I had never heard of Blue John when I came to these parts. It is the name given to a peculiar mineral of a beautiful purple shade, which is only found at one or two places in the world. It is so rare that an ordinary vase of Blue John would be valued at a great price. The Romans, with that extraordinary instinct of theirs, discovered that it was to be found in this valley, and sank a horizontal shaft deep into the mountain side. The opening of their mine has been called Blue John Gap, a clean-cut arch in the rock, the mouth all overgrown with bushes. It is a goodly passage which the Roman miners have cut, and it intersects some of the great water-worn caves, so that if you enter Blue John Gap you would do well to mark your steps and to have a good store of candles, or you may never make your way back to the daylight again. I have not yet gone deeply into it, but this very day I stood at the mouth of the arched tunnel, and peering down into the black recesses beyond, I vowed that when my health returned I would devote some holiday to exploring those mysterious depths and finding out for myself how far the Roman had penetrated into the Derbyshire hills.

Strange how superstitious these countrymen are! I should have thought better of young Armitage, for he is a man of some education and character, and a very fine fellow for his station in life. I was standing at the Blue John Gap when he came across the field to me.

"Well, doctor," said he, "you're not afraid, anyhow."

"Afraid!" I answered. "Afraid of what?"

"Of it," said he, with a jerk of his thumb towards the black vault, "of the Terror that lives in the Blue John Cave."

How absurdly easy it is for a legend to arise in a lonely countryside! I examined him as to the reasons for his weird belief. It seems that from time to time sheep have been missing from the fields, carried bodily away, according to Armitage. That they could have wandered away of their own accord and disappeared among the mountains was an explanation to which he would not listen. On one occasion a pool of blood had been found, and some tufts of wool. That also, I pointed out, could be explained in a perfectly natural way. Further, the nights upon which sheep disappeared were invariably very dark, cloudy nights with no moon. This I met with the obvious retort that those were the nights which a commonplace sheep-stealer would naturally choose for his work. On one occasion a gap had been made in a wall, and some of the stones scattered for a considerable distance. Human agency again, in my opinion. Finally, Armitage clinched all his arguments by telling me that he had actually heard the Creature--indeed, that anyone could hear it who remained long enough at the Gap. It was a distant roaring of an immense volume. I could not but smile at this, knowing, as I do, the strange reverberations which come out of an underground water system running amid the chasms of a limestone formation. My incredulity annoyed Armitage so that he turned and left me with some abruptness.

And now comes the queer point about the whole business. I was still standing near the mouth of the cave turning over in my mind the various statements of Armitage, and reflecting how readily they could be explained away, when suddenly, from the depth of the tunnel beside me, there issued a most extraordinary sound. How shall I describe it? First of all, it seemed to be a great distance away, far down in the bowels of the earth. Secondly, in spite of this suggestion of distance, it was very loud. Lastly, it was not a boom, nor a crash, such as one would associate with falling water or tumbling rock, but it was a high whine, tremulous and vibrating, almost like the whinnying of a horse. It was certainly a most remarkable experience, and one which for a moment, I must admit, gave a new significance to Armitage's words. I waited by the Blue John Gap for half an hour or more, but there was no return of the sound, so at last I wandered back to the farmhouse, rather mystified by what had occurred. Decidedly I shall explore that cavern when my strength is restored. Of course, Armitage's explanation is too absurd for discussion, and yet that sound was certainly very strange. It still rings in my ears as I write.

April 20.--In the last three days I have made several expeditions to the Blue John Gap, and have even penetrated some short distance, but my bicycle lantern is so small and weak that I dare not trust myself very far. I shall do the thing more systematically. I have heard no sound at all, and could almost believe that I had been the victim of some hallucination suggested, perhaps, by Armitage's conversation. Of course, the whole idea is absurd, and yet I must confess that those bushes at the entrance of the cave do present an appearance as if some heavy creature had forced its way through them. I begin to be keenly interested. I have said nothing to the Miss Allertons, for they are quite superstitious enough already, but I have bought some candles, and mean to investigate for myself.

I observed this morning that among the numerous tufts of sheep's wool which lay among the bushes near the cavern there was one which was smeared with blood. Of course, my reason tells me that if sheep wander into such rocky places they are likely to injure themselves, and yet somehow that splash of crimson gave me a sudden shock, and for a moment I found myself shrinking back in horror from the old Roman arch. A fetid breath seemed to ooze from the black depths into which I peered. Could it indeed be possible that some nameless thing, some dreadful presence, was lurking down yonder? I should have been incapable of such feelings in the days of my strength, but one grows more nervous and fanciful when one's health is shaken.

For the moment I weakened in my resolution, and was ready to leave the secret of the old mine, if one exists, for ever unsolved. But tonight my interest has returned and my nerves grown more steady. Tomorrow I trust that I shall have gone more deeply into this matter.

April 22.--Let me try and set down as accurately as I can my extraordinary experience of yesterday. I started in the afternoon, and made my way to the Blue John Gap. I confess that my misgivings returned as I gazed into its depths, and I wished that I had brought a companion to share my exploration. Finally, with a return of resolution, I lit my candle, pushed my way through the briars, and descended into the rocky shaft.

It went down at an acute angle for some fifty feet, the floor being covered with broken stone. Thence there extended a long, straight passage cut in the solid rock. I am no geologist, but the lining of this corridor was certainly of some harder material than limestone, for there were points where I could actually see the tool-marks which the old miners had left in their excavation, as fresh as if they had been done yesterday. Down this strange, old-world corridor I stumbled, my feeble flame throwing a dim circle of light around me, which made the shadows beyond the more threatening and obscure. Finally, I came to a spot where the Roman tunnel opened into a water-worn cavern--a huge hall, hung with long white icicles of lime deposit. From this central chamber I could dimly perceive that a number of passages worn by the subterranean streams wound away into the depths of the earth. I was standing there wondering whether I had better return, or whether I dare venture farther into this dangerous labyrinth, when my eyes fell upon something at my feet which strongly arrested my attention.

The greater part of the floor of the cavern was covered with boulders of rock or with hard incrustations of lime, but at this particular point there had been a drip from the distant roof, which had left a patch of soft mud. In the very centre of this there was a huge mark--an ill-defined blotch, deep, broad and irregular, as if a great boulder had fallen upon it. No loose stone lay near, however, nor was there anything to account for the impression. It was far too large to be caused by any possible animal, and besides, there was only the one, and the patch of mud was of such a size that no reasonable stride could have covered it. As I rose from the examination of that singular mark and then looked round into the black shadows which hemmed me in, I must confess that I felt for a moment a most unpleasant sinking of my heart, and that, do what I could, the candle trembled in my outstretched hand.

I soon recovered my nerve, however, when I reflected how absurd it was to associate so huge and shapeless a mark with the track of any known animal. Even an elephant could not have produced it. I determined, therefore, that I would not be scared by vague and senseless fears from carrying out my exploration. Before proceeding, I took good note of a curious rock formation in the wall by which I could recognize the entrance of the Roman tunnel. The precaution was very necessary, for the great cave, so far as I could see it, was intersected by passages. Having made sure of my position, and reassured myself by examining my spare candles and my matches, I advanced slowly over the rocky and uneven surface of the cavern.

And now I come to the point where I met with such sudden and desperate disaster. A stream, some twenty feet broad, ran across my path, and I walked for some little distance along the bank to find a spot where I could cross dry-shod. Finally, I came to a place where a single flat boulder lay near the centre, which I could reach in a stride. As it chanced, however, the rock had been cut away and made top-heavy by the rush of the stream, so that
