Farther the road winds first amongst the broken ridges of the Koh-i-Mulla Khwaja, then over the intervening dasht into the southern spurs of the Paropamisus to the Ardewan pass.
In width, called the Dasht-i-Hamdamao, or Dasht-i-Ardewan, formed by the talus or drift of the higher mountains, which, washed down through centuries of denudation, now forms long sweeping spurs of gravel and sand, scantily clothed with wormwood scrub and almost destitute of water.
Through this stretch of dasht the drainage from the main water-divide breaks downwards to the plains of Herat, where it is arrested and utilized for irrigation purposes.
Persian Baluchistan forms an administrative division of the province of Kerman and is subdivided into the following twenty districts: - (1) Bampur; (2) Serhad; (3) Dizek; (4) Jalk; (5) Sib; (6) Irafshan; (7) Magas; (8) Serbaz; (9) Lashar; (io) Champ; (II) Fannuj; (12) Bazman; (13) Aptar; (14) Daman; (15) Aprandagan; (16) Asfehgeh; (17) Surmij; (18) Meskutan; (19) Pushteh; (20) Makran, the country of the Ichthyophagi, with the subdistricts Kasrkand, Geh, Bint, Dasht, Kucheh and Bahu.
It is on the whole a route across open plains and hard, stony " dasht" - a route which would offer no great difficulties to that railway extension from Chaman which has so long been contemplated.
The Hab river, which forms the boundary west of Karachi; the Purali (the ancient Arabus), which drains the low-lying flats of Las Bela; the Hingol (the ancient Tomerus) and the Dasht, which drain Makran, are all considerable streams, draining into the Arabian Sea and forming important arteries in the network of internal communication.
