The Bunnoo Valley is surrounded by hills on every side — on the 

 north by the hills of the Caubul Kheye Wuzeerees which are a conti- 

 nuation of the Sooliman range, on the south by the Batannee range : 

 on the east by the Khattuck hills ; and on the west by the Sooliman 

 range. I am not possessed of any geological information regarding 

 the Caubul Kheye hills. The Batannee hills strike off at an acute 

 angle from the Sooliman range on the west, proceed at first in a south- 

 easterly direction until they reach Peyzoo ; and then run eastwards 

 across the Murwut Valley ; and terminate by sloping off towards the 

 Indus at the junction of this river with the Koorum below Esan 

 Kheyl. The portion of the range next to the Sooliman hills is called 

 the Peyzoo hills, which terminate at Peyzoo. The next portion is 

 called Shaikh Boodeen, which is about 6 miles in length, and termi- 

 nates in sand [sandstone ?] hills (the highest of which is about 1200 

 feet above the plain below,) which form the termination of the whole 

 range. 



The Peyzoo hills are irregular, wavy, sand [sandstone ?] hills with 

 two passes through them— the first, next the Sooliman range, being 

 called the Baenderra ; the second the Peyzoo pass. I have not 

 obtained any fossils from these hills. Each pass is intersected by 

 numerous nullahs. 



Shaikh Boodeen is about 4,500 feet above the level of the sea ; and 

 the little hill station on its summit is the frontier Sanatorium. The 

 general dip of the strata is towards the north, and their strike from east 

 to west. The angle which the dip forms with the horizon is a good 

 deal more than a right angle. The upper portion of the hills is com- 

 posed chiefly of limestone, which very often is stained red and yellow 

 by peroxide and bisulphuret [?] of Iron. Lower down the hill, there is 

 more claystone mixed with blocks of limestone; and at the foot of the 

 hill, we meet with the low sand [sandstone ?] hills continued from the 

 Peyzoo range. This lowermost portion of the hill, is in many places 

 covered with the debris of the higher parts, in the form of broken rocks
