As it may be supposed, I wrote immediately to my friend, thanking him for the copy of the inscription, and asking him in a casual manner the history of the incident he mentioned. To be brief, I heard that a woman named Cradock, who had lost her husband a day before, had set out to communicate the sad news to a cousin who lived some five miles away. She took a short cut which led by the Grey Hills. Mrs. Cradock, who was then quite a young woman, never arrived at her relative's house. Late that night a farmer, who had lost a couple of sheep, supposed to have wandered from the flock, was walking over the Grey Hills, with a lantern and his dog. His attention was attracted by a noise, which he described as a kind of wailing, mournful and pitiable to hear; and, guided by the sound, he found the unfortunate Mrs. Cradock crouched on the ground by the limestone rock, swaying her body to and fro, and lamenting and crying in so heart-rending a manner that the farmer was, as he says, at first obliged to stop his ears, or he would have run away. The woman allowed herself to be taken home, and a neighbour came to see to her necessities. All the night she never ceased her crying, mixing her lament with words of some unintelligible jargon, and when the doctor arrived he pronounced her insane. She lay on her bed for a week, now wailing, as people said, like one lost and damned for eternity, and now sunk in a heavy coma; it was thought that grief at the loss of her husband had unsettled her mind, and the medical man did not at one time expect her to live. I need not say that I was deeply interested in this story, and I made my friend write to me at intervals with all the particulars of the case. I heard then that in the course of six weeks the woman gradually recovered the use of her faculties, and some months later she gave birth to a son, christened Jervase, who unhappily proved to be of weak intellect. Such were the facts known to the village; but to me, while I whitened at the suggested thought of the hideous enormities that had doubtless been committed, all this was nothing short of conviction, and I incautiously hazarded a hint of something like the truth to some scientific friends. The moment the words had left my lips I bitterly regretted having spoken, and thus given away the great secret of my life, but with a good deal of relief mixed with indignation I found my fears altogether misplaced, for my friends ridiculed me to my face, and I was regarded as a madman; and beneath a natural anger I chuckled to myself, feeling as secure amidst these blockheads as if I had confided what I knew to the desert sands.
But now, knowing so much, I resolved I would know all, and I concentrated my efforts on the task of deciphering the inscription on the Black Seal. For many years I made this puzzle the sole object of my leisure moments, for the greater portion of my time was, of course, devoted to other duties, and it was only now and then that I could snatch a week of clear research. If I were to tell the full history of this curious investigation, this statement would be wearisome in the extreme, for it would contain simply the account of long and tedious failure. But what I knew already of ancient scripts I was well equipped for the chase, as I always termed it to myself. I had correspondents amongst all the scientific men in Europe, and, indeed, in the world, and I could not believe that in these days any character, however ancient and however perplexed, could long resist the search-light I should bring to bear upon it. Yet in point of fact, it was fully fourteen years before I succeeded. With every year my professional duties increased and my leisure became smaller. This no doubt retarded me a good deal; and yet, when I look back on those years, I am astonished at the vast scope of my investigation of the Black Seal. I made my bureau a centre, and from all the world and from all the ages I gathered transcripts of ancient writing.
Nothing, I resolved, should pass me unawares, and the faintest hint should be welcomed and followed up. But as one covert after another was tried and proved empty of result, I began in the course of years to despair, and to wonder whether the Black Seal were the sole relic of some race that had vanished from the world, and left no other trace of its existence--had perished, in fine, as Atlantis is said to have done, in some great cataclysm, its secrets perhaps drowned beneath the ocean or moulded into the heart of the hills. The thought chilled my warmth a little, and though I still persevered, it was no longer with the same certainty of faith. A chance came to the rescue. I was staying in a considerable town in the north of England, and took the opportunity of going over the very creditable museum that had for some time been established in the place. The curator was one of my correspondents; and, as we were looking through one of the mineral cases, my attention was struck by a specimen, a piece of black stone some four inches square, the appearance of which reminded me in a measure of the Black Seal. I took it up carelessly, and was turning it over in my hand, when I saw, to my astonishment, that the under side was inscribed. I said, quietly enough, to my friend the curator that the specimen interested me, and that I should be much obliged if he would allow me to take it with me to my hotel for a couple of days. He, of course, made no objection, and I hurried to my rooms and found that my first glance had not deceived me. There were two inscriptions; one in the regular cuneiform character, another in the character of the Black Seal, and I realized that my task was accomplished. I made an exact copy of the two inscriptions; and when I got to my London study, and had the seal before me, I was able seriously to grapple with the great problem. The interpreting inscription on the museum specimen, though in itself curious enough, did not bear on my quest, but the transliteration made me master of the secret of the Black Seal. Conjucture, of course, had to enter into my calculations; there was here and there uncertainty about a particular ideograph, and one sign recurring again and again on the seal baffled me for many successive nights. But at last the secret stood open before me in plain English, and I read the key of the awful transmutation of the hills. The last word was hardly written, when with fingers all trembling and unsteady I tore the scrap of paper into the minutest fragments, and saw them flame and blacken in the red hollow of the fire, and then I crushed the grey films that remained into finest powder. Never since then have I written those words; never will I write the phrases which tell how man can be reduced to the slime from which he came, and be forced to put on the flesh of the reptile and the snake.
