The Great Pyramid, as all the world, knows, is composed of enormous blocks of granite, each about three feet high, and arranged after the fashion of enormous steps. The entrance to the passage which leads to the interior is on the thirteenth tier, and nearly fifty feet from the ground. With a feeling of awe which may be very well understood, when I reached it I paused before entering. I did not know on the threshold of what discovery I might be standing. And what was more, I reflected that if Pharos found me following him, my life would in all probability pay the forfeit. My curiosity, however, was greater than my judgment, and being determined, since I had come so far, not to go back without learning all there was to know, I hardened my heart, and, stooping down, entered the passage. When I say that it is less than four feet in height, and of but little more than the same width, and that for the first portion of the way the path slopes downward at an angle of twenty-six degrees, some vague idea may be obtained of the unpleasant place it is. But if I go on to add that the journey had to be undertaken in total darkness, without any sort of knowledge of what lay before me, or whether I should ever be able to find my way out again, the foolhardiness of the undertaking will be even more apparent. Step by step, and with a caution which I can scarcely exaggerate, I made my way down the incline, trying every inch before I put my weight upon it and feeling the walls carefully with either hand in order to make sure that no other passages branched off to right or left. After I had been advancing for what seemed an interminable period, but could not in reality have been more than five minutes. I found myself brought to a standstill by a solid wall of stone. For a moment I was at a loss how to proceed. Then I found that there was a turn in the passage, and the path, instead of continuing to descend, was beginning to work upward, whereupon, still feeling my way as before, I continued my journey of exploration. The heat was stifling, and more than once foul things, that only could have been bats, flapped against my face and hands and sent a cold shudder flying over me. Had I dared for a moment to think of the immense quantity of stone that towered above me, or what my fate would be had a stone fallen from its place and blocked the path behind me, I believe I should have been lost for good and all. But, frightened as I was, a greater terror was in store for me.
