It was indeed to me a torturing and offensive problem that this man, who had so bounteously rescued me from the sharpness of death, and showed himself in all the relations of life full of benevolence, and pity, and kindly forethought, should so manifestly be for once on the side of the demons, and take a ghastly pleasure in the torments of an afflicted fellow creature. Apart, I struggled with the horned difficulty, and strove to find the solution; but without the hint of a clue, beset by mystery and contradiction. I saw nothing that might help me, and began to wonder whether, after all, I had not escaped from the white mist of the suburb at too dear a rate. I hinted something of my thought to the professor; I said enough to let him know that I was in the most acute perplexity, but the moment after regretted what I had done when I saw his face contort with a spasm of pain.

'My dear Miss Lally,' he said, 'you surely do not wish to leave us? No, no, you would not do it. You do not know how I rely on you; how confidently I go forward, assured that you are here to watch over my children. You, Miss Lally, are my rear-guard; for let me tell you the business in which I am engaged is not wholly devoid of peril. You have not forgotten what I said the first morning here; my lips are shut by an old and firm resolve till they can open to utter no ingenious hypothesis or vague surmise, but irrefragable fact, as certain as a demonstration in mathematics. Think over it, Miss Lally; not for a moment would I endeavour to keep you here against your own instincts, and yet I tell you frankly that I am persuaded it is here, here amidst the woods, that your duty lies.'

I was touched by the eloquence of his tone, and by the remembrance that the man, after all, had been my salvation, and I gave him my hand on a promise to serve him loyally and without question. A few days later the rector of our church—a little church, grey and severe and quaint, that hovered on the very banks of the river and watched the tides swim and return—came to see us, and Professor Gregg easily persuaded him to stay and share our dinner. Mr. Meyrick was a member of an antique family of squires, whose old manor-house stood amongst the hills some seven miles away, and thus rooted in the soil, the rector was a living store of all the old fading customs and lore of the country. His manner, genial, with a deal of retired oddity, won on Professor Gregg; and towards the cheese, when a curious Burgundy had begun its incantations, the two men glowed like the wine, and talked of philology with the enthusiasm of a burgess over the peerage. The parson was expounding the pronunciation of the Welsh ll, and producing sounds like the gurgle of his native brooks, when Professor Gregg struck in.

'By the way,' he said, 'that was a very odd word I met with the other day. You know my boy, poor Jervase Cradock? Well, he has got the bad habit of talking to himself, and the day before yesterday I was walking in the garden here and heard him; he was evidently quite unconscious of my presence. A lot of what he said I couldn't make out, but one word struck me distinctly. It was such an odd sound, half sibilant, half guttural, and as quaint as those double l's you have been demonstrating. I do not know whether I can give you an idea of the sound; 'Ishakshar' is perhaps as near as I can get. But the k ought to be a Greek chi or a Spanish j. Now what does it mean in Welsh?'

'In Welsh?' said the parson. 'There is no such word in Welsh, nor any word remotely resembling it. I know the book-Welsh, as they call it, and the colloquial dialects as well as any man, but there's no word like that from Anglesea to Usk. Besides, none of the Cradocks speak a word of Welsh; it's dying out about here.'

'Really. You interest me extremely, Mr. Meyrick. I confess the word didn't strike me as having the Welsh ring. But I thought it might be some local corruption.'

'No, I never heard such a word, or anything like it. Indeed,' he added, smiling whimsically, 'if it belongs to any language, I should say it must be that of the fairies—the Tylwydd Têg, as we call them.'

The talk went on to the discovery of a Roman villa in the neighbourhood; and soon after I left the room, and sat down apart to wonder at the drawing together of such strange clues of evidence. As the professor had spoken of the curious word, I had caught the glint in his eye upon me; and though the pronunciation he gave was grotesque in the extreme, I recognized the name of the stone of sixty characters mentioned by Solinus, the black seal shut up in some secret drawer of the study, stamped for ever by a vanished race with signs that no man could read, signs that might, for all I knew, be the veils of awful things done long ago, and forgotten before the hills were moulded into form.

When the next morning I came down, I found Professor Gregg pacing the terrace in his eternal walk.

'Look at that bridge,' he said, when he saw me; 'observe the quaint and Gothic design, the angles between the arches, and the silvery grey of the stone in the awe of the morning light. I confess it seems to me symbolic; it should illustrate a mystical allegory of the passage from one world to another.'

'Professor Gregg,' I said quietly, 'it is time that I knew something of what has happened, and of what is to happen.'

For the moment he put me off, but I returned again with the same question in the evening, and then Professor Gregg flamed with excitement. 'Don't you understand yet?' he cried.
