Andarab is fortunately a fixed position. The description given of it by Idrisi places it at the junction of the Kaisan (or Kasan) stream with the Andarab, both of which retain their ancient names. Andarab is a very old and a very important position in all itineraries, from Greek times till now, and it may be important again. But seeing that Khulm is separated from Talekan by four days, it is difficult to distinguish between Semenjan and Warwalin which is also two days from each of those places. This illustrates the problems which beset the unravelling of Arab itineraries. Seeing, however, that Talekan and Warwalin have already been confused once, it is, I think, justifiable to assume that the same mistake has occurred again. Such an assumption would place Semenjan about where Haibak is, and where some central town of importance must have always been, judging from its important geographical position. Haibak is rather more than a hundred miles from Andarab by the only practicable khafila route, which is a very fair five-days' journey. This would indicate that the route followed by the English Commission for the settlement of the Russo-Afghan frontier from Balkh to Kabul was one of those recognized as trade routes in the tenth and eleventh centuries. The location of one other town in Badakshan is of interest, and that is a town called by Idrisi "Badakshan," which gave its name to the province. The first assumption to make is that the modern capital Faizabad is on or near the site of the ancient one. Let us see how it fits Idrisi's itinerary. The information is most meagre. From Talekan to Badakshan, seven days. From Andarab to the same town (going east), four days. Badakshan is described as a town "not very large but possessing many dependencies and a most fertile soil. The vine and other trees grow freely, and the country is watered by running streams. The town is defended by strong walls, and it possesses markets, caravanserais, and baths. It is a commercial centre. It is built on the west bank of the Khariab, the largest river of those which flow to the Oxus." It is elsewhere stated that the Khariab is another name for the Oxus or Jihun. It is added that horses are bred there and mules; and rubies and lapis lazuli found in the neighbourhood and distributed through the world. Musk from Wakhan is brought to Badakshan. Also Badakshan adjoins Canouj, a dependency of India. The two provinces which are found immediately beyond the Oxus (under one government) are Djil and Waksh, which lie between the Khariab (? Oxus) and Wakshab rivers, of which the first bathes the eastern part of Djil and the other the country of Waksh. The Waksh joins the Oxus from the north near the junction of the latter with the Kunduz. Then follow the names of places dependent on Waksh, of which Helawerd and Menk seem to be the chief.
