"Visitors," he said, "are rare. You'll be very welcome. The railway will take you within a hundred miles; the last hundred miles will be accomplished on the back of a dromedary; I shall send you a fleet one and an escort." "Splendid," I answered. "I see myself arriving sitting high up on the hump gathering dates--I suppose there are date palms where you are? Yes?--and wearing a turban and a bournous." "Would you like to see my bournous?" he said, and opening his valise he showed me a splendid one which filled me with admiration, and only shame forbade me to ask him to allow me to try it on. Ideas haunt one. When I was a little child I insisted on wearing a turban and going out for a ride on the pony, flourishing a Damascus blade which my father had brought home from the East. Nothing else would have satisfied me; my father led the pony, and I have always thought this fantasy exceedingly characteristic; it must be so, for it awoke in me twenty years afterwards; and fanciful and absurd as it may appear, I certainly should have liked to have worn my travelling companion's bournous in the train if only for a few minutes. All this is twelve years ago, and I have not yet gone to visit him in his oasis, but how many times have I done so in my imagination, seeing myself arriving on the back of a dromedary crying out, "Allah! Allah! And Mohammed is his prophet!" But though one can go on thinking year after year about a bournous, one cannot talk for more than two or three hours about one; and though I looked forward to spending at least a fortnight with my friends, and making excursions in the desert, finding summer, as Fromentin says, _chez lui_, I was glad to say good-bye to my friends at Marseilles.
