had seen and heard before at sunrise and sunset, and judged it was a normal thing. I decided it came from some rock fissure leading to a cave, and watched the troubled sand to trace it to its source; soon perceiving that it came from the black orifice of a temple a long distance south of me almost out of sight. Against the choking sand-cloud I plodded toward this temple, which, as I neared it, loomed larger than the rest, and showed a doorway far less clogged with caked sand. I would have entered had not the terrific force of the icy wind almost quenched my torch. It poured madly out of the dark door, sighing uncannily as it ruffled the sand and spread among the weird ruins. Soon it grew fainter and the sand grew more and more still, till finally all was at rest again; but a presence seemed stalking among the spectral stones of the city, and when I glanced at the moon it seemed to quiver as though mirrored in unquiet waters. I was more afraid than I could explain, but not enough to dull my thirst for wonder; so as soon as the wind was quite gone I crossed into the dark chamber from which it had come.
This temple, as I had fancied from the outside, was larger than either of those I had visited before; and was presumably a natural cavern since it bore winds from some region beyond. Here I could stand quite upright, but saw that the stones and altars were as low as those in the other temples. On the walls and roof I beheld for the first time some traces of the pictorial art of the ancient race, curious curling streaks of paint that had almost faded or crumbled away; and on two of the altars I saw with rising excitement a maze of well-fashioned curvilinear carvings. As I held my torch aloft it seemed to me that the shape of the roof was too regular to be natural, and I wondered what the prehistoric cutters of stone had first worked upon. Their engineering skill must have been vast.
Then a bright flare of the fantastic flame showed me that for which I had been seeking, the opening to those remoter abysses whence the sudden wind had blown; and I grew faint when I saw that it was a small and plainly artificial door chiselled in the solid rock. I thrust my torch within, beholding a black tunnel with the roof arching low over a rough flight of very small, numerous, and steeply descending steps. I shall always see those steps in my dreams, for I came to learn what they meant. At the time I hardly knew whether to call them steps or mere footholds in a precipitous descent. My mind was whirling with mad thoughts, and the words and warnings of Arab prophets seemed to float across the desert from the lands that men know to the nameless city that men dare not know. Yet I hesitated only a moment before advancing through the portal and commencing to climb cautiously down the steep passage, feet first, as though on a ladder.
It is only in the terrible phantasms of drugs or delirium that any other man can have such a descent as mine. The narrow passage led infinitely down like some hideous haunted well, and the torch I held above my head could not light the unknown depths toward which I was crawling. I lost track of the hours and forgot to consult my watch, though I was frightened when I thought of the distance I must be traversing. There were changes of direction and of steepness; and once I came to a long, low level passage
