It must have been past four o'clock in the afternoon, and I was for returning to tea at my aunt's, when underneath the stone on which I sat I heard a rumbling and crumbling, and on jumping off saw that the crack in the ground had still further widened, just where it came up to the tomb, and that the dry earth had so shrunk and settled that there was a hole in the ground a foot or more across. Now this hole reached under the big stone that formed one side of the tomb, and falling on my hands and knees and looking down it, I perceived that there was under the monument a larger cavity, into which the hole opened. I believe there never was boy yet who saw a hole in the ground, or a cave in a hill, or much more an underground passage, but longed incontinently to be into it and discover whither it led. So it was with me; and seeing that the earth had fallen enough into the hole to open a way under the stone, I slipped myself in feet foremost, dropped down on to a heap of fallen mould, and found that I could stand upright under the monument itself. Now this was what I had expected, for I thought that there had been below this grave a vault, the roof of which had given way and let the earth fall in. But as soon as my eyes were used to the dimmer light, I saw that it was no such thing, but that the hole into which I had crept was only the mouth of a passage, which sloped gently down in the direction of the church. My heart fell to thumping with eagerness and surprise, for I thought I had made a wonderful discovery, and that this hidden way would certainly lead to great things, perhaps even to Blackbeard's hoard; for ever since Mr. Glennie's tale I had constantly before my eyes a vision of the diamond and the wealth it was to bring me. The passage was two paces broad, as high as a tall man, and cut through the soil, without bricks or any other lining; and what surprised me most was that it did not seem deserted nor mouldy and cob-webbed, as one would expect such a place to be, but rather a well-used thoroughfare; for I could see the soft clay floor was trodden with the prints of many boots, and marked with a trail as if some heavy thing had been dragged over it. So I set out down the passage, reaching out my hand before me lest I should run against anything in the dark, and sliding my feet slowly to avoid pitfalls in the floor. But before I had gone half a dozen paces, the darkness grew so black that I was frightened, and so far from going on was glad to turn sharp about, and see the glimmer of light that came in through the hole under the tomb. Then a horror of the darkness seized me, and before I well knew what I was about I found myself wriggling my body up under the tombstone on to the churchyard grass, and was once more in the low evening sunlight and the soft sweet air.
