'He doesn't seem quite all there, I don't think, miss,' was her comment, and later in the day I saw him helping the old man who worked in the garden. He was a youth of about fourteen, with black hair and black eyes and an olive skin, and I saw at once from the curious vacancy of his expression that he was mentally weak. He touched his forehead awkwardly as I went by, and I heard him answering the gardener in a queer, harsh voice that caught my attention; it gave me the impression of some one speaking deep below under the earth, and there was a strange sibilance, like the hissing of the phonograph as the pointer travels over the cylinder. I heard that he seemed anxious to do what he could, and was quite docile and obedient, and Morgan the gardener, who knew his mother, assured me he was perfectly harmless. 'He's always been a bit queer,' he said, 'and no wonder, after what his mother went through before he was born. I did know his father, Thomas Cradock, well, and a very fine workman he was too, indeed. He got something wrong with his lungs owing to working in the wet woods, and never got over it, and went off quite sudden like. And they do say as how Mrs. Cradock was quite off her head: anyhow, she was found by Mr. Hillyer, Ty Coch, all crouched up on the Grey Hills, over there, crying and weeping like a lost soul. And Jervase, he was born about eight months afterwards, and, as I was saying, he was a bit queer always; and they do say when he could scarcely walk he would frighten the other children into fits with the noises he would make.'

A word in the story had stirred up some remembrance within me, and, vaguely curious, I asked the old man where the Grey Hills were.

'Up there,' he said, with the same gesture he had used before; 'you go past the "Fox and Hounds", and through the forest, by the old ruins. It's a good five mile from here, and a strange sort of a place. The poorest soil between this and Monmouth, they do say, though it's good feed for sheep. Yes, it was a sad thing for poor Mrs. Cradock.'

The old man turned to his work, and I strolled on down the path between the espaliers, gnarled and gouty with age, thinking of the story I had heard, and groping for the point in it that had some key to my memory. In an instant it came before me; I had seen the phrase 'Grey Hills' on the slip of yellowed paper that Professor Gregg had taken from the drawer in his cabinet. Again I was seized with pangs of mingled curiosity and fear; I remembered the strange characters copied from the limestone rock, and then again their identity with the inscription of the age-old seal, and the fantastic fables of the Latin geographer. I saw beyond doubt that, unless coincidence had set all the scene and disposed all these bizarre events with curious art, I was to be a spectator of things far removed from the usual and customary traffic and jostle of life. Professor Gregg I noted day by day; he was hot on his trail, growing lean with eagerness; and in the evenings, when the sun was swimming on the verge of the mountain, he would pace the terrace to and fro with his eyes on the ground, while the mist grew white in the valley, and the stillness of the evening brought far voices near, and the blue smoke rose a straight column from the diamond-shaped chimney of the grey farmhouse, just as I had seen it on the first morning. I have told you I was of sceptical habit; but though I understood little or nothing, I began to dread, vainly proposing to myself the iterated dogmas of science that all life is material, and that in the system of things there is no undiscovered land, even beyond the remotest stars, where the supernatural can find a footing. Yet there struck in on this the thought that matter is as really awful and unknown as spirit, that science itself but dallies on the threshold, scarcely gaining more than a glimpse of the wonders of the inner place.

There is one day that stands up from amidst the others as a grim red beacon, betokening evil to come. I was sitting on a bench in the garden, watching the boy Cradock weeding, when I was suddenly alarmed by a harsh and choking sound, like the cry of a wild beast in anguish, and I was unspeakably shocked to see the unfortunate lad standing in full view before me, his whole body quivering and shaking at short intervals as though shocks of electricity were passing through him, his teeth grinding, foam gathering on his lips, and his face all swollen and blackened to a hideous mask of humanity. I shrieked with terror, and Professor Gregg came running; and as I pointed to Cradock, the boy with one convulsive shudder fell face forward, and lay on the wet earth, his body writhing like a wounded blind-worm, and an inconceivable babble of sounds bursting and rattling and hissing from his lips. He seemed to pour forth an infamous jargon, with words, or what seemed words, that might have belonged to a tongue dead since untold ages and buried deep beneath Nilotic mud, or in the inmost recesses of the Mexican forest. For a moment the thought passed through my mind, as my ears were still revolted with that infernal clamour, 'Surely this is the very speech of hell,' and then I cried out again and again, and ran away shuddering to my inmost soul. I had seen Professor Gregg's face as he stooped over the wretched boy and raised him, and I was appalled by the glow of exultation that shone on every lineament and feature. As I sat in my room with drawn blinds, and my eyes hidden in my hands, I heard heavy steps beneath, and I was told afterwards that Professor Gregg had carried Cradock to his study, and had locked the door. I heard voices murmur indistinctly, and I trembled to think of what might be passing within a few feet of where I sat; I longed to escape to the woods and sunshine, and yet I dreaded the sights that might confront me on the way; and at last, as I held the handle of the door nervously, I heard Professor Gregg's voice calling to me with a cheerful ring. 'It's all right now, Miss Lally,' he said. 'The poor fellow has got over it, and I have been arranging for him to sleep here after tomorrow. Perhaps I may be able to do something for him.'

'Yes,' he said later, 'it was a very painful sight, and I don't wonder you were alarmed. We may hope that good food will build him up a little, but I am afraid he will never be really cured,' and he affected the dismal and conventional air with which one speaks of hopeless illness; and yet beneath it I detected the delight that leapt up rampant within him, and fought and struggled to find utterance. It was as if one glanced down on the even surface of the sea, clear and immobile, and saw beneath raging depths and a storm of contending billows.
