I knew it at once:  I had lain a special fuse-train in the great palace at the top of the terraces:  it was the royal palace, Yildiz.

Up and up we went through the grounds, a few unburned old bodies in rags of uniform still discernible here and there as the lantern swung past them, a musician in sky-blue, a fantassin and officer-of-the-guard in scarlet, forming a cross, with domestics of the palace in red-and-orange.

The palace itself was quite in ruins, together with all its surrounding barracks, mosque, and seraglio, and, as we reached the top of the grounds, presented a picture very like those which I have seen of the ruins of Persepolis, only that here the columns, both standing and fallen, were innumerable, and all more or less blackened; and through doorless doors we passed, down immensely-wide short flights of steps, and up them, and over strewed courtyards, by tottering fragments of arcades, all roofless, and tracts of charcoal between interrupted avenues of pillars, I following, expectant, and she very eager now.  Finally, down a flight of twelve or fourteen rather steep and narrow steps, very dislocated, we went to a level which, I thought, must be the floor of the palace vaults:  for at the bottom of the steps we stood on a large plain floor of plaster, which bore the marks of the flames; and over this the girl ran a few steps, pointed with excited recognition to a hole in it, ran further, and disappeared down the hole.

When I followed, and lowered the lantern a little, I saw that the drop down was about eight feet, made less than six feet by a heap of stone-rubbish below, the falling of which had caused the hole:  and it was by standing on this rubbish-heap, I knew at once, that she must have been enabled to climb out into the world.

I dropped down, and found myself in a low flat-roofed cellar, with a floor of black earth, very fusty and damp, but so very vast in extent that even in the day-time, I suppose, I could not have discerned its boundaries; I fancy, indeed, that it extends beneath the whole palace and its environs—­an enormous stretch of space:  with the lantern I could only see a very limited portion of its area.  She still led me eagerly on, and I presently came upon a whole region of flat boxes, each about two feet square, and nine inches high, made of very thin laths, packed to the roof; and about a-hundred-and-fifty feet from these I saw, where she pointed, another region of bottles, fat-bellied bottles in chemises of wicker-work, stretching away into gloom and total darkness.  The boxes, of which a great number lay broken open, as they can be by merely pulling with the fingers at a pliant crack, contain dates; and the bottles, of which many thousands lay empty, contain, I saw, old Ismidtwine.  Some fifty or sixty casks, covered with mildew, some old pieces of furniture, and a great cube of rotting, curling parchments, showed that this cellar had been more or less loosely used for the occasional storage of superfluous stores and knick-knacks.
