DESCRIPTIVE GEOLOGY: SLATE ZONE. 143 



mountain-slope above are represented together. The variegated 

 sandstone, with smudged and wavy lines of carbonaceous material, in 

 addition to the bed of coal, is shewn dipping at 8o° W.N.W. along 

 with the neighbouring limestones. The section ascends towards the 

 west-north-west. 



On the east side of the second anticlinal there is also another ex- 

 posure of the coal-bearing bed, not so good apparently as the one to 

 the west. I could not examine it myself, but fragments of coal were 

 brought to me from it. At the point X in the above section there 

 are Nummulitic shales visible on the Bunyan ridge, but none lower 

 down the slope. I conclude that the shales have furnished a line of 

 weakness, along which the strata have yielded and slipped ; similar 

 movements having taken place along the line of the Jura-Cretaceous 

 at a a. The two broken anticlinals indicated by a a ) and exposed in 

 the gorge, continue north-north-east up the hill-sides for a long way, 

 their exposures being narrow strips only and following depression 

 on the slopes or the run of a stream-bed. The south-eastern one dies 

 out under Musta peak (8,435 feet), and the north-western one passes 

 across the main ridge to the other side by a small gap and joins up 

 with the prominent band exposed on the north-eastern scarps of the 

 main ridge. 



Continuing up the Hertoh river along its right bank by a some- 

 what precarious foot-path, which runs high above the final abyss, 

 until we reach the point where the gorge turns to the north- 

 east, we cross over a continuous section in the Nummulitic limestone, 

 dipping as before steeply to the north-west or west-north-west until 

 the strike of Gulee is reached, when the faulting and folding begin 

 which introduce the Jura-Cretaceous band ipreviously referred to as 

 passing by Bandee and Kuthwal. The Cretaceous and the brown 

 sandstones beneath display here a fair proportion of fossils, but want 

 of time prevented me from visting the locality again for the pur- 

 pose of collecting them. 



Following the right bank of the north-east reach of the 

 Hertoh along the road to Tandiani, but considerably above the bed
