The gateway of a caravanserai is lined within on either side by a narrow platform, on which you can sit enjoying rest and shelter, smoking your kalyan and drinking your cup of tea. At Kharzan a wood-fire was burning merrily upon the bricks of one of these platforms; various Persians who were cooking and warming themselves over it made room for us when they saw us approaching, and gave us steaming glasses of tea, which we drank gratefully. There was a good deal of coming and going through the archway: laden donkeys and men wrapped in coats of sheepskin over their blue cotton garments appeared suddenly out of the mist and disappeared as suddenly into it; the crackling sticks sent bright jets of firelight flickering over wild faces and the rough coats of men and animals. Leaving Kharzan, we turned down the pass between mountain sides bare now after the summer’s scorching, but where in the spring we had seen masses of scarlet tulips in full bloom. The lower slopes in spring and autumn are covered with the black tent roofs and yellow reed walls of nomads driving their flocks from lowland pastures up to mountain-tops when the snow melts, and back to the valleys when the winter returns. But the season was well advanced when we passed, and the mountains were already deserted. As we descended, slipping down steep places and stumbling over shelving rocks, the sun began to play that old game of his by which he loves to prove himself superior to wind and storms. We loosened and finally stripped off waterproofs, coats and cloaks, and fastened them behind our saddles; but nothing would satisfy him--he blazed more and more furiously upon the narrow, open path and upon the walls of rock and upon us, until we regretted the chill mist which still lay upon the Kharzan Pass behind us. At length we reached the bottom of the hill and crossed a stony river-bed, overgrown with tamarisk bushes, at the further side of which stood a post-house, with some fig-trees in front of it. The post-house of Paichenar is not an agreeable resting-place. It is a ‘murmurous haunt of flies’ even on late autumn afternoons: flies are served up with your roast chicken, flies flavour your pillau, flies swim in your wine, they buzz through the tiny rooms, and creep up the whitewashed walls, regardless of the caustic references to their presence which are written up in all languages by travellers whose patience they have tried beyond endurance. Flies are so illiterate; not one of those many tongues appeals to them.
