Well, my friends, I knew this well, for I was no stranger to the nomadic life, and accordingly, without fear of the fierce-eyed throng who came forth to meet us, I made my respects to the Sheikh Saïd Mohammed, and was reckoned by him as a friend and a brother. His tent was placed at my disposal and provisions were made for the suitable entertainment of those who were with me. You know how dusk falls in Egypt? At one moment the sky is a brilliant canvas, glorious with every color known to art, at the next the curtain--the wonderful veil of deepest violet--has fallen; the stars break through it like diamonds through the finest gauze; it is night, velvet, violet night. You see it here in this noisy modern Cairo. In the lonely desert it is ten thousand times grander, ten thousand times more impressive; it speaks to the soul with the voice of the silence. Ah, those desert nights! So was the night of which I speak; and having partaken of the fare which the Sheikh caused to be set before me--and Bedouin fare is not for the squeamish stomach--I sipped that delicious coffee which, though an acquired taste, is the true nectar, and looked out beyond the four or five palm trees of this little oasis to where the gray carpet of the desert grew black as ebony and met the violet sweep of the sky. Perhaps I was the first to see him; I cannot say; but certainly he was not perceived by the Bedouins, although one stood on guard at the entrance to the camp. How can I describe him? At the time, as he approached in the moonlight with a shambling, stooping gait, I felt that I had never seen his like before. Now I know the reason of my wonder, and the reason of my doubt. I know what it was about him which inspired a kind of horror and a revulsion--a dread. Elfin locks he had, gray and matted, falling about his angular face, shading his strange, yellow eyes. His was dressed in rags, in tatters; he was furtive, and he staggered as one who is very weak, slowly approaching out of the vastness. Then it appeared as though every dog in the camp knew of his coming. Out from the shadows of the tents they poured, those yapping mongrels. Never have I seen such a thing. In the midst of the yellowish, snarling things, at the very entrance to the camp, the wretched old man fell, uttering a low cry. But now, snatching up a heavy club which lay close to my hand, I rushed out of the tent. Others were thronging out too, but, first of them all, I burst in among the dogs, striking, kicking, and shouting. I stooped and raised the head of the stranger. Mutely he thanked me, with half-closed eyes. A choking sound issued from his throat, and he clutched with his hands and pointed to his mouth.
