Once more I began my questions, and they answered them willingly. There and then I heard that secret for which many had died in old time, the secret of the heather ale. They told of the gold in the hills, of corries where the sand gleamed and abysses where the rocks were veined. All this they told me, freely, without a scruple. And then, like a clap, came the awful thought that this, too, spelled death. These were secrets which this race aforetime had guarded with their lives; they told them generously to me because there was no fear of betrayal. I should go no more out from this place. The thought put me into a new sweat of terror--not at death, mind you, but at the unknown horrors which might precede the final suffering. I lay silent, and after binding my hands they began to leave me and go off to other parts of the cave. I dozed in the horrible half-swoon of fear, conscious only of my shaking limbs, and the great dull glow of the fire in the centre. Then I became calmer. After all, they had treated me with tolerable kindness: I had spoken their language, which few of their victims could have done for many a century; it might be that I had found favour in their eyes. For a little I comforted myself with this delusion, till I caught sight of a wooden box in a corner. It was of modern make, one such as grocers use to pack provisions in. It had some address nailed on it, and an aimless curiosity compelled me to creep thither and read it. A torn and weather-stained scrap of paper, with the nails at the corner rusty with age; but something of the address might still be made out. Amid the stains my feverish eyes read, "To Mr M----, Carrickfey, by Allerfoot Station." The ruined cottage in the hollow of the waste with the single gnarled apple-tree was before me in a twinkling. I remembered the shepherd's shrinking from the place and the name, and his wild eyes when he told me of the thing that had happened there. I seemed to see the old man in his moorland cottage, thinking no evil; the sudden entry of the nameless things; and then the eyes glazed in unspeakable terror. I felt my lips dry and burning. Above me was the vault of rock; in the distance I saw the fire-glow and the shadows of shapes moving around it. My fright was too great for inaction, so I crept from the couch, and silently, stealthily, with tottering steps and bursting heart, I began to reconnoitre.
