T HE mountainous and relatively inaccessible country of Kuhgalu lies south-east of Bakhtiari Country and runs as a strip of highlands some 50 miles wide to the Bushire and Shiraz road. On the south-western side there is an expanse of broken foothills where red rocks and white gypsum build up a zone of low variegated difficult country, and on the north-eastern side the ragged irregular mountains of the watershed separate the several plains along the high edge of the inland plateau which constitutes the centre of Iran. Kuhgalu has an area of about 8000 square miles. The Khirsin, the largest tributary of the Karun river, the Marun, flowing not far from Behbehan, and the rivers Zuhreh and Shapur share the drainage with the Qara Aghach or Mund river except for a small part on the north-east edge which lies in the basin of the Rud Kur a river discharging into the salt lake of Niriz, which has no outlet. The giants amongst a welter of considerable mountain ranges are Kuh-i-Khami on the south-west, Kuh-i-Alvarz in the central part, and the spectacular range of Kuh-i-Dina near the northern margin. These mountain fortresses have long been the home of a group of restless tribes, the Boir Ahmadi, the Mamasani, the Taybi, the Bahmis, and the Dushtmanziari, who have now been brought to order by the present strong Government under the control of H.I.M. Riza Shah.
