of the steep slopes. It behoves the traveller, therefore, to arrange 

 his own roads, and even turn engineer on occasions. 



Sections south-east of Huveliyan and Rnjoeeuh. 



We must now turn back along the strike of the Slate zone to that 

 portion of it lying to the south-east of Huveliyan and Rujoeeuh on 

 the Dore river, from which, as a starting-point, I shall now describe a 

 set of strike areas forming the south-eastern portion of the Slate zone. 



About 2! miles due south of Huveliyan appears the thin end of a 



wedge of Trias limestone, let in among the slates 

 Sections near Sari- 



wali, Kotluh, and by a fault on its north-western side. It is a 



Oochar. , . , ., . . , . . ., 



mere strip, % mile wide, and about \ mile long. 



In the direction of its strike towards the north-east this band is in- 

 terrupted by a mile of alluvium, after which another exposure of the 

 same band appears as a short low ridge, \ mile long, followed almost 

 immediately by a much longer outcrop of the same band, which also 

 widens slightly, in the direction of Kotluh. In addition to the Trias 

 limestone exposed in the last outcrop, a representative of the Jura- 

 Cretaceous band, and a trace of the Grey limestone, strike diagonally 

 across the run of the faulted mass. A view and section of this band 

 is given below, fig. 16 : —
