For several hours I remained in one position, musing over my strange situation and wondering what the final outcome would be. At last, after the sun had gone down and darkness began to encircle me, I decided to look about and find a suitable place to lie down and sleep for the night. So I began to climb from rock to rock until I had reached the opposite side of the jagged plateau, when suddenly one of the great stones wobbled, I lost my balance and slid down an incline into a sort of a pit. Then my feet struck something which momentarily stopped my unexpected descent, but it proved to be a mere shell, and crashing through it I landed with a violent jolt about ten feet further below. Although somewhat stunned and a trifle confused by the suddenness of the fall, I quickly regained my equanimity and looking upward I saw a small hole which my body had passed through, the shaggy rocks above, the dark sky and a few stars, but the strangest thing of all was, that the grotto into which I had fallen was as light as day. CHAPTER V After all I had passed through during the preceding twenty-four hours, then to be suddenly cast from the outer darkness into a hole as light as if illuminated by the mid-day sun was a revelation that caused me to seriously doubt my own senses. But having spent a life of travel and adventure in which I had faced many unexpected dangers and inexplicable sights, I soon regained my normal presence of mind and began to look around with considerable interest. I was now fully convinced that the great pile of stone which I had so strangely reached had at one time formed a gigantic structure moulded together by human ingenuity. The enclosure I found myself within might have been a hallway of the edifice, but it was hard to positively distinguish it as such, for the building in falling had placed things in an almost unrecognizable condition. Some of the great stones from above had passed through the ceiling and floor, while others had become wedged together before reaching the surface, thus forming a very ragged and peculiar aperture. In places where there were no obstructions I noticed a beautiful white marble floor, while here and there a fragment of the walls showed that the art of decorating had at one time reached a degree of proficiency quite unapproachable by our modern artists. The space I found myself in was too irregular in its outlines to form an adequate idea of what it might have been used for. In some places I had to stoop to pass along, while in others I was forced to climb over great blocks of stone.
