It is reported that since the Russo-Afghan Commission surveyors passed that way, the late Amir has constructed a passable road for commercial purposes, which can be kept open by the employment of coolie labour in removing the snow, and that khafilas pass freely between Kabul and Badakshan all the year round. In the tenth century there is ample evidence that it was a well-trodden route, for we find it stated that from Andarab to Hariana (travelling southward) is three days' journey. "Hariana is a small town built at the foot of a mountain and on the banks of a river, which, taking its source near Panjshir (Banjohir) traverses that town without being utilized for irrigation until, reaching Karwan, it enters into the territory of India and joins its waters to the Nahrwara (Kabul) River. The inhabitants of Hariana possess neither trees nor orchards. They only cultivate vegetables, but they live by mining. It is impossible to see anything more perfect than the metal which is extracted from the mines of Panjshir, a small town built on a hill at one day's distance from Hariana and of which the inhabitants are remarkable for violence and wickedness (mechanceté) of their character. The river, which issues from Panjshir, runs to Hariana as we have said." ... "From there (? Hariana) to Karwan, southward, two days' journey." "The town of Karwan is small but pretty, its environs are agreeable, bazaars frequent, inhabitants well-off. The houses are built of mud and bricks. Situated on the banks of a river which comes from Panjshir, this town is one of the principal markets of India." From this account it is clear that the village of Panjshir must have been somewhere near the modern Khawak, and Hariana about 20 miles lower down the stream. But the site is not identified. Karwan was obviously near the site of the modern Charikar, and might possibly be Parwan, a very ancient site. It is worthy of note that in the tenth century all the Kabul province was "India." Of all the passes traversing the Hindu Kush we have mention only of this, the Khawak, and (indirectly) of the group which connect Kabul with Bamian; and it may be doubted whether in the Middle Ages any use was made of the Shibar, Chapdara, or others that lie between the Kaoshan and Irak for commercial purposes. There is, however, strong inference that the Greeks made use of the Kaoshan, or Parwan, which is also commanded from Andarab. The excellent military road constructed by the late Amir from Charikar, up the Ghorband valley and over the Chapdara Pass, is a modern development.
