The operation turned out a more dizzy one than I had anticipated. No guide was necessary, for we could see the track winding like a thread up the face of the precipice. For the first three hundred feet or so it was all plain sailing, but then the ledge became horribly narrow. Occasionally the path was so steep that it dwindled into rock-cut steps. A false step would have sent you thundering hundreds of feet down into the abyss. At one place the height was so dizzy, the foothold so slight, that my nerve, which for this sort of work is not what it once was, began to give way, and I ignominiously squatted down, with my face turned to the rock, and tried to steady myself by forgetting that six inches behind me was a yawning chasm, from which a pebble might have been dropped plumb to the bottom. Retreat was as bad as advance, and more humiliating. For the rest of the way I went on my hands and knees, to the amusement of my companion, whose brain was not similarly affected. I don't know anything more disagreeable than the irresistible impulse which overtakes one sometimes to pitch one's self headlong over a precipice of this kind. At last, to my inexpressible relief, I reached the mouth of a cave, into which I sprawled, panting, with thankfulness, but oppressed nevertheless with the horrible consciousness that I had the return voyage still to make. However, I dismissed this painful consideration for the moment, and applied myself to the examination of the curious grotto which we had reached. It was a sort of ante-chamber to a tunnel in the rock, passing through which we came upon some dreadful steps out on the face of the rock; but here there was a slight, rickety balustrade of wood, and at the top stood a greasy old monk, a sight which, under the circumstances, produced a more soothing effect upon my mind than such a sight usually does. This ecclesiastical worthy received us with gracious smiles, and led us through another tunnel into a sort of vestibule, which opened into a chapel which had been constructed at the mouth of a cave, so that the front facing the precipice was of masonry. Looking out of the window which had been constructed in this wall, a stone might have been dropped at least five hundred feet without touching anything till it reached the bottom. This chapel was gorgeously fitted up, thanks to the contributions of pilgrims whose heads must have been steadier than mine was. It had a handsomely decorated screen covered with sacred designs richly gilt. The apse was six feet in diameter, and the total length from the inside of the apse to the back of the cave about twenty-five feet, the breadth being about twenty. A door led out of this chapel into a narrow passage and up two or three steps into another cave, or niche, where there was a figure of a saint.
