Marco Polo now entered the rocky mountainous kingdom of the Balkhs, whose kings claim descent from Alexander the Great; a cold country, producing good fast horses, excellent falcons, and all kinds of game. Here, too, are prolific ruby-mines worked by the king and which yield large quantities, but they are so strictly enclosed that no one on pain of death may set foot on the Sighinan mountain containing the mines. In other places silver is found, and many precious stones, of which he says "they make the finest azure in the world," meaning lapis-lazuli; his stay in this part of the country must have been a long one to have enabled him to observe so many of its characteristics. Ten days' journey from hence he entered a province which must be the Peshawur of the present day, whose dark-skinned inhabitants were idolaters; then after seven days' further march, about mid-day he came to the kingdom of Cashmere, where the temperature is cool, and towns and villages are very numerous. Had Marco Polo continued his route in the same direction he would soon have reached the territory of India, but instead of that he took a northerly course, and in twelve days was in Vaccan, a land watered by the Upper Oxus, which runs through splendid pastures, where feed immense flocks of wild sheep, called mufflons. Thence he went through a mountainous country, lying between the Altai and Himalayan ranges to Kashgar. Here Marco Polo's route is the same as that of his uncle and his father during their first voyage, when from Bokhara they were taken to the residence of the great khan. From Kashgar, Marco Polo diverged a little to the west, to Samarcand, a large town inhabited by Saracens and Christians, then to Yarkand, a city frequented by caravans trading between India and Northern Asia; passing by Khotan, the capital of the province of that name, and by Pein, a town whose situation is uncertain, but in a part of the country where chalcedony and jasper abound. He came to the kingdom of Kharachar, which extends along the borders of the desert of Jobe; then after five days' further travelling over sandy plains, where there was no water fit to drink, he rested for eight days in the city of Lob, a place now in ruins, while he prepared to cross the desert lying to the east, "so great a desert," he says, "that it would require a year to traverse its whole length, a haunted wilderness, where drums and other instruments are heard, though invisible."
