The moon was gleaming vividly over the primitive ruins, lighting a dense cloud of sand that seemed blown by a strong but decreasing wind from some point along the cliff ahead of me. I knew it was this chilly, sandy wind which had disturbed the camel and was about to lead him to a place of better shelter when I chanced to glance up and saw that there was no wind atop the cliff. This astonished me and made me fearful again, but I immediately recalled the sudden local winds that I 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.
