But there were two close by each other which seemed to continue on. There was not much choice between them, but, as both made in the same direction, as far as I could judge the direction in which I had so far progressed, I decided to take the larger one. It proved to be a passage much like the tunnel I had already traversed, only a little roomier, and therefore it was easier going, and it, too, brought me out, as had the other, on another cavern—but one considerably larger in extent.

Here, however, I speedily perceived that it was not a case of one cavern, but several—opening out, by natural archways one into another. I walked eagerly through them, scanning their ceilings for sign of some outlet into the upper air; but in vain. Still, after the strangling embrace of those tunnels, it was good to have so much space to breathe and walk about in. In fact, I had stumbled on something like a Monte Cristo suite of underground apartments. And here for a moment I released my imagination from her blinders, and allowed her to play around these strange halls. And in one of her suggestions there was some comfort. It was hardly likely that caverns of such extent had waited for me to discover them. They must surely have been known to Teach, or whatever buccaneer it was who had occupied the ruined mansion not so very far above-ground. What better place could be conceived for his business? It was even likely—more than likely, almost certain—that there was some secret passageway connecting this series of caves with the old house—if one could only find it. And so the dear creature prattled on to me, till I thought it was time to blindfold her again—and return to business.

Still, there was something in what she had said, and I set about the more carefully to examine every nook and corner. And, if I didn't find anything so splendid as she had dreamed, I did presently find evidence that, as she had said, I was not the first human being to stand where now I stood. Two iron staples imbedded in one of the walls, with rusting chains and manacles attached, were melancholy proof of one of the uses to which the place had once been put. Melancholy for certain unhappy souls long since free of all mortal chains, but for me—need I say it?—exceedingly joyous. For if there had been a way to bring prisoners here, it was none the less evident that there had been a way to take them out. But how and where? Again I searched every nook and cranny. There was no sign of entrance anywhere.

Then a thought occurred to me. What if the entrance were after the manner of a mediæval oubliette—through the ceiling! There was a thought indeed to send one's hopes soaring. I ran in my eagerness through one cavern after another, holding my lantern aloft. That must be the solution. There could be no other way. I sought and sought, but alas! it was a false hope, and I threw myself down in a corner in despair, deciding that the prisoners must have been forced to crawl in as I had—though it was hardly like jailers to put themselves to such inconvenience.

I leaned back against the wall and gazed listlessly upward. Next moment I had bounded to my feet again. Surely I had seen some short regular lines running up the face of the rock, like a ladder. I raised my lantern. Sure enough, they were iron rounds set in the face of the rock, and they mounted up till I lost them in the obscurity, for the cave here must have been forty feet high. Blessed heaven! I was saved!

But alas! they did not begin till some six feet above my head, and the wall was sheer. How was I to reach the lowest rung? The rock was too sheer for me to cut steps in, as I had done farther back. I looked about me. Again the luck was with me. In one of the caves I had noticed some broken pieces of fallen rock. They were terribly heavy, but despair lent me strength, and after an hour or two's work, I had managed to roll several of them to the foot of the ladder, and—with an effort of which I would not have believed myself capable—had been able to build them one on top of another against the wall. So, I found myself able to grasp the lowest rung with my hands. Then, fastening the lantern round my neck with my necktie, I prepared to mount.

The climb was not difficult, once I had managed to get my feet on the first rung of the ladder, but there was always the chance that one of the rungs might have rusted loose with time, in which case, of course, it would have given way in my grasp, and I should have been precipitated backward to certain death below.

However, the man who had mortised them had done an honest piece of work, and they proved as firm as on the day they were placed there. Up and up I went, till I must have been forty feet above the floor, and, then, as I neared the roof, instead of coming to a trap door, as I had conjectured, I found that the ladder came to an end at the edge of a narrow ledge, running along the ceiling much as a clerestory runs near the roof of some old churches. On to this I managed to climb. It was barely a yard wide, and the impending roof did not permit of one's standing erect. It was a dizzy situation, and it seemed safest to crawl along on all fours, holding the lantern in front of me. Presently it brought me up sharp in a narrow recess. It had come to an end.

Yes! but imagine my joy! it had come to an end at a low archway rudely cut in the rock. Deep set in the archway was a stout wooden door. My first thought was that I was trapped again, but, to my infinite surprise and gratitude, it proved to be slightly ajar, and a vigorous push sent it grinding back on its hinges. What next! I wondered. At all events, I was no longer lost in the bowels of the earth; step by step, I was coming nearer to the frontiers of humanity.

But I was certainly not prepared for what next met my eyes, as I pushed through the low doorway with my lantern, and looked around. Yes! indeed, man had certainly been here, man, too, very purposeful and businesslike. I was in a sort of low narrow gallery, some forty feet long, to which the arching rock made a crypt-like ceiling. At my first glance, I saw that there was another door at the far end similar to the one I had entered by; and on the left side of the gallery, built of rough stones from the low ceiling to the floor, was a series of compartments, each with locked wooden door. They were strong and grim looking, and might have been taken for prison cells, or family vaults, or possibly wine-bins. The massive locks were red with rust, and there was plainly no possibility of my opening them.
