Hatasu's Temple presents a lively enough scene in the daytime during the winter and early spring months, with the streams of tourists constantly passing from the white causeway to Cook's Rest House on the edge of the desert. There had been a goodly number of visitors that day to the temple below, and one or two of the more curious and venturesome had scrambled up the steep path to the little plateau which was the scene of my operations. None had penetrated beyond the notice boards, however, and now, with the evening sky passing through those innumerable shades which defy palette and brush, which can only be distinguished by the trained eye, but which, from palest blue melt into exquisite pink, and by some magical combination form that deep violet which does not exist to perfection elsewhere than in the skies of Egypt, I found myself in the silence and the solitude of "the Holy Valley." I stood at the edge of the plateau, looking out at the rosy belt which marked the course of the distant Nile, with the Arabian hills vaguely sketched beyond. The rocks stood up against that prospect as great black smudges, and what I could see of the causeway looked like a gray smear upon a drab canvas. Beneath me were the chambers of the Rock Temple, with those wall paintings depicting events in the reign of Hatasu which rank among the wonders of Egypt. Not a sound disturbed my reverie, save a faint clatter of cooking utensils from the camp behind me--a desecration of that sacred solitude. Then a dog began to howl in the neighboring village. The dog ceased, and faintly to my ears came the note of a reed pipe. The breeze died away, and with it the piping. I turned back to the camp, and, having partaken of a frugal supper, turned in upon my campaigner's bed, thoroughly enjoying my freedom from the routine of official life in Cairo, and looking forward to the morrow's work pleasurably. Under such circumstances a man sleeps well; and when, in an uncanny gray half-light, which probably heralded the dawn, I awoke with a start, I knew that something of an unusual nature alone could have disturbed my slumbers. Firstly, then, I identified this with a concerted howling of the village dogs. They seemed to have conspired to make night hideous; I have never heard such an eerie din in my life. Then it gradually began to die away, and I realized, secondly, that the howling of the dogs and my own awakening might be due to some common cause. This idea grew upon me, and as the howling subsided, a sort of disquiet possessed me, and, despite my efforts to shake it off, grew more urgent with the passing of every moment. In short, I fancied that the thing which had alarmed or enraged the dogs was passing from the village through the Holy Valley, upward to the Temple, upward to the plateau, and was approaching _me_.
