Both it and the Jurassics can be 

 followed mile after mile 

 along the hill-sides in a 

 perfectly continuous ex- 

 posure. 1 



As regards the Nummu- 

 litics of the ridge, sections 

 south-east of Naruh show 

 numbers of parallel scarps 

 and little valleys, the former 

 being uncultivated bare 

 rough limestone, and the 

 latter excavated along the 

 shaley layers and furnish- 

 ing a scanty soil for culti- 

 vation. These undulating 

 waves of hard and soft rock 



give way at the crest of the ridge to a steep rough descent over 

 tumbled blocks of limestone down to the Jura-Cretaceous horizon. 

 At Naruh, on the northern side of the Nummulitic zone, there is a 

 certain amount of grey limestone exposed, but generally along the 

 boundary fault between the Nummulitic and Slate zones the 

 opposition of uppermost .Nummulitics against slates is as complete 

 an indication of the magnitude of the dislocation as could be 

 wished. 



South-west of Suttoruh the sections across the ridge become 

 complicated by the Trias dividing into two bands with a long inlier 

 of Jura-Cretaceous and Nummulitic limestone wedged in between 

 them. The section north-west and south-east of Chinjah shews this 

 in ill-exposed forest-covered hill-sides. A better section is given 

 from near Jubriyan via Lussun to the main ridge south-west of 

 Balkooh ; but even here the working out of the structure of the higher 

 parts is rendered difficult by the dense small forest. 



1 It has always been a puzzle to me why on Wynne's map the Jura-Cretaceous band 

 along this line of country is omitted.
