A somewhat extensive course of miscellaneous and obsolete reading had done a great deal to prepare the way, and, later, when I became somewhat of a specialist, and immersed myself in the studies known as ethnological, I was now and then startled by facts that would not square with orthodox scientific opinion, and by discoveries that seemed to hint at something still hidden for all our research. More particularly I became convinced that much of the folk-lore of the world is but an exaggerated account of events that really happened, and I was especially drawn to consider the stories of the fairies, the good folk of the Celtic races. Here, I thought I could detect the fringe of embroidery and exaggeration, the fantastic guise, the little people dressed in green and gold sporting in the flowers, and I thought I saw a distinct analogy between the name given to this race (supposed to be imaginary) and the description of their appearance and manners. Just as our remote ancestors called the dreaded beings 'fair' and 'good' precisely because they dreaded them, so they had dressed them up in charming forms, knowing the truth to be the very reverse. Literature, too, had gone early to work, and had lent a powerful hand in the transformation, so that the playful elves of Shakespere are already far removed from the true original, and the real horror is disguised in a form of prankish mischief. But in the older tales, the stories that used to make men cross themselves as they sat around the burning logs, we tread a different stage; I saw a widely opposed spirit in certain histories of children and of men and women who vanished strangely from the earth. They would be seen by a peasant in the fields walking towards some green and rounded hillock, and seen no more on earth; and there are stories of mothers who have left a child quietly sleeping, with the cottage door rudely barred with a piece of wood, and have returned, not to find the plump and rosy little Saxon, but a thin and wizened creature, with sallow skin and black, piercing eyes, the child of another race. Then, again, there were myths darker still; the dread of witch and wizard, the lurid evil of the Sabbath, and the hint of demons who mingled with the daughters of men. And just as we have turned the terrible 'fair folk' into a company of benignant, if freakish elves, so we have hidden from us the black foulness of the witch and her companions under a popular diablerie of old women and broomsticks, and a comic cat with tail on end. So the Greeks called the hideous furies benevolent ladies, and thus the northern nations have followed their example. I pursued my investigations, stealing odd hours from other and more imperative labours, and I asked myself the question: Supposing these traditions to be true, who were the demons who are reported to have attended the Sabbaths? I need not say that I laid aside what I may call the supernatural hypothesis of the Middle Ages, and came to the conclusion that fairies and devils were of one and the same race and origin; invention, no doubt, and the Gothic fancy of old days, had done much in the way of exaggeration and distortion; yet I firmly believe that beneath all this imagery there was a black background of truth. As for some of the alleged wonders, I hesitated. While I should be very loath to receive any one specific instance of modern spiritualism as containing even a grain of the genuine, yet I was not wholly prepared to deny that human flesh may now and then, once perhaps in ten millions cases, be the veil of powers which seem magical to us—powers which, so far from proceeding from the heights and leading men thither, are in reality survivals from the depths of being. The amoeba and the snail have powers which we do not possess; and I thought it possible that the theory of reversion might explain many things which seem wholly inexplicable. Thus stood my position; I saw good reason to believe that much of the tradition, a vast deal of the earliest and uncorrupted tradition of the so-called fairies, represented solid fact, and I thought that the purely supernatural element in these traditions was to be accounted for on the hypothesis that a race which had fallen out of the grand march of evolution might have retained, as a survival, certain powers which would be to us wholly miraculous. Such was my theory as it stood conceived in my mind; and working with this in view, I seemed to gather confirmation from every side, from the spoils of a tumulus or a barrow, from a local paper reporting an antiquarian meeting in the country, and from general literature of all kinds. Amongst other instances, I remember being struck by the phrase 'articulate-speaking men' in Homer, as if the writer knew or had heard of men whose speech was so rude that it could hardly be termed articulate; and on my hypothesis of a race who had lagged far behind the rest, I could easily conceive that such a folk would speak a jargon but little removed from the inarticulate noises of brute beasts.

Thus I stood, satisfied that my conjecture was at all events not far removed from fact, when a chance paragraph in a small country print one day arrested my attention. It was a short account of what was to all appearance the usual sordid tragedy of the village—a young girl unaccountably missing, and evil rumour blatant and busy with her reputation. Yet I could read between the lines that all this scandal was purely hypothetical, and in all probability invented to account for what was in any other manner unaccountable. A flight to London or Liverpool, or an undiscovered body lying with a weight about its neck in the foul depths of a woodland pool, or perhaps murder—such were the theories of the wretched girl's neighbours. But as I idly scanned the paragraph, a flash of thought passed through me with the violence of an electric shock: what if the obscure and horrible race of the hills still survived, still remained haunting wild places and barren hills, and now and then repeating the evil of Gothic legend, unchanged and unchangeable as the Turanian Shelta, or the Basques of Spain? I have said that the thought came with violence; and indeed I drew in my breath sharply, and clung with both hands to my elbow-chair, in a strange confusion of horror and elation. It was as if one of my confrères of physical science, roaming in a quiet English wood, had been suddenly stricken aghast by the presence of the slimy and loathsome terror of the ichthyosaurus, the original of the stories of the awful worms killed by valourous knights, or had seen the sun darkened by the pterodactyl, the dragon of tradition. Yet as a resolute explorer of knowledge, the thought of such a discovery threw me into a passion of joy, and I cut out the slip from the paper and put it in a drawer in my old bureau, resolved that it should be but the first piece in a collection of the strangest significance. I sat long that evening dreaming of the conclusions I should establish, nor did cooler reflection at first dash my confidence. Yet as I began to put the case fairly, I saw that I might be building on an unstable foundation; the facts might possibly be in accordance with local opinion, and I regarded the affair with a mood of some reserve. Yet I resolved to remain perched on the look-out, and I hugged to myself the thought that I alone was watching and wakeful, while the great crowd of thinkers and searchers stood heedless and indifferent, perhaps letting the most prerogative facts pass by unnoticed.

Several years elapsed before I was enabled to add to the contents of the drawer; and the second find was in reality not a valuable one, for it was a mere repetition of the first, with only the variation of another and distant locality. Yet I gained something; for in the second case, as in the first, the tragedy took place in a desolate and lonely country, and so far my theory seemed justified. But the third piece was to me far more decisive. Again, amongst outland hills, far even from a main road of traffic, an old man was found done to death, and the instrument of execution was left beside him. Here, indeed, there were rumour and conjecture, for the deadly tool was a primitive stone axe, bound by gut to the wooden handle, and surmises the most extravagant and improbable were indulged in.
