The Palace faced the Nile, which showed like a tortuous band of blue and silver a mile or so away. Nothing lay between but the brown sand, and here and there a handful of dark figures gliding towards the river, or a little train of camels making for the bare grey hills from the ghiassas which had given them their desert loads. The course of the Nile was marked by a wide fringe of palms showing blue and purple, friendly and ancient and solitary. Beyond the river and the palms lay the grey-brown desert, faintly touched with red. So clear was the sweet evening air that the irregular surface of the desert showed for a score of miles as plainly as though it were but a step away. Hummocks of sand--tombs and fallen monuments gave a feeling as of forgotten and buried peoples; and the two vast pyramids of Sakkarah stood up in the plaintive glow of the evening skies, majestic and solemn, faithful to the dissolved and absorbed races who had built them. Curtains of mauve and saffron-red were hung behind them, and through a break of cloud fringing the horizon a yellow glow poured, to touch the tips of the pyramids with poignant splendour. But farther over to the right, where Cairo lay, there hung a bluish mist, palpable and delicate, out of which emerged the vast pyramids of Cheops; and beside it the smiling inscrutable Sphinx faced the changeless centuries. Beyond the pyramids the mist deepened into a vast deep cloud of blue and purple, which seemed the end to some mystic highway untravelled by the sons of men. Suddenly there swept over David a wave of feeling such as had passed over Kaid, though of a different nature. Those who had built the pyramids were gone, Cheops and Thotmes and Amenhotep and Chefron and the rest. There had been reformers in those lost races; one age had sought to better the last, one man had toiled to save--yet there only remained offensive bundles of mummied flesh and bone and a handful of relics in tombs fifty centuries old. Was it all, then, futile? Did it matter, then, whether one man laboured or a race aspired? Only for a moment these thoughts passed through his mind; and then, as the glow through the broken cloud on the opposite horizon suddenly faded, and veils of melancholy fell over the desert and the river and the palms, there rose a call, sweetly shrill, undoubtingly insistent. Sunset had come, and, with it, the Muezzin's call to prayer from the minaret of a mosque hard by. David was conscious of a movement behind him--that Kaid was praying with hands uplifted; and out on the sands between the window and the river he saw kneeling figures here and there, saw the camel-drivers halt their trains, and face the East with hands uplifted. The call went on--"La ilaha illa-llah !"
