surrounding valley. As the river approaches the Mirjawa plain, 

 terraces of recent gravel and of silt are largely developed. The Ladis 

 river is a tributary of the Mirjawa river, which under the name of 

 Tahlab river enters the Hamun-i-Mashkhel. The terraces seen here 

 just as those north of Dalbandin (page 61) and elsewhere are no 

 doubt connected with the former existence of a much higher water- 

 level in the Hamun-i-Mashkhel depression. 



When travelling from Ladis to visit the K6h-i-Tafdcin, I followed 

 the course of the Ladis river and of one of its tributaries towards the 

 village of Timi, which enabled me to examine the ancient strata ex- 

 posed along its bank as far as the point where they become concealed 

 beneath the recent volcanic deposits of the K6h-i-Tafd£n. The direc- 

 tion followed is roughly south-south west, which is practically at 

 right angles to the strike of the ranges. At first the strata are the 

 same tertiary slates and limestones as at Ladis. These are followed 

 by volcanic rocks with the flysch facies, then again by a syncline 

 of tertiary strata, and once more by the flysch which are the rocks 

 exposed at the point where they become concealed beneath the es- 

 carpment of the recent ash-beds from the volcano (see frontispiece). 

 An inlier of the same rocks rises amidst the ash-beds at Timi.
