Their leader advanced to Billali, saluted him by placing his ivory wand transversely across his forehead, and then asked some question which I could not catch, and Billali having answered him the whole regiment turned and marched along the side of the cliff, our cavalcade of litters following in their track.  After going thus for about half a mile we halted once more in front of the mouth of a tremendous cave, measuring about sixty feet in height by eighty wide, and here Billali descended finally, and requested Job and myself to do the same.  Leo, of course, was far too ill to do anything of the sort.  I did so, and we entered the great cave, into which the light of the setting sun penetrated for some distance, while beyond the reach of the daylight it was faintly illuminated with lamps which seemed to me to stretch away for an almost immeasurable distance, like the gas lights of an empty London street.  The first thing I noticed was that the walls were covered with sculptures in bas-relief, of a sort, pictorially speaking, similar to those that I have described upon the vases;—­love-scenes principally, then hunting pictures, pictures of executions, and the torture of criminals by the placing of a, presumably, red-hot pot upon the head, showing whence our hosts had derived this pleasant practice.  There were very few battle-pieces, though many of duels, and men running and wrestling, and from this fact I am led to believe that this people were not much subject to attack by exterior foes, either on account of the isolation of their position or because of their great strength.  Between the pictures were columns of stone characters of a formation absolutely new to me; at any rate, they were neither Greek nor Egyptian, nor Hebrew, nor Assyrian—­that I am sure of.  They looked more like Chinese writings than any other that I am acquainted with.  Near to the entrance of the cave both pictures and writings were worn away, but further in they were in many cases absolutely fresh and perfect as the day on which the sculptor had ceased work on them.

The regiment of guards did not come further than the entrance to the cave, where they formed up to let us pass through.  On entering the place itself we were, however, met by a man robed in white, who bowed humbly, but said nothing, which, as it afterwards appeared that he was a deaf mute, was not very wonderful.

Running at right angles to the great cave, at a distance of some twenty feet from the entrance, was a smaller cave or wide gallery, that was pierced into the rock both to the right and to the left of the main cavern.  In front of the gallery to our left stood two guards, from which circumstance I argued that it was the entrance to the apartments of She herself.  The mouth of the right-hand gallery was unguarded, and along it the mute indicated that we were to go.  Walking a few yards down this passage, which was lighted with lamps, we came to the entrance of a chamber having
