SKETCH OF THE 



country, the western limits of the formation described at Bandi, and 

 exhibiting in their course different appearances. The granitic rocks found 

 in the neighbourhood of S/iapoora, fourteen miles east of jBan ? a, are pro- 

 bably a continuation of this series, while a continuation of the Bantra 

 rocks may probably be discovered in those to the west of Nasirahad. 



Proceeding east from Nasirabad, in the direction of Biana, we pass, in 

 the first instance, through the same bleak and desolate country — the rocks 

 every where appearing at the surface. We have still alternations of gra- 

 nitic rocks and hornblende rocks, with numerous low rounded swells, com- 

 posed of pure white quartz, large masses of which latter strew the line of 

 march. The granitic rocks lose, at a short distance to the east of Nasi- 

 rabad, their stratiform structure, and frequently appear at the surface in 

 the form of immense lenticular masses, often many yards in diameter, the 

 superior flattened surfaces of which only protrude ; and we also observe 

 the piled up heaps of globular masses above alluded to. This formation 

 is obviously a continuation of that observed at Bandi. Proceeding east as 

 far as Bamholi, about thirty miles distant from Nasirabad, we have a 

 continuation of a similar variety of rocks, but micaceous and chlorite schists 

 now occasionally make their appearance ; the granites, however, prepon- 

 derate, and in these the felspar is the most abundant ingredient. It is 

 frequently of a crumbling nature. Among other varieties of granite which 

 occur near BamboU, there was one of a very beautiful appearance com- 

 posed of quartz-hornblende, the last in very small proportion — flesh- 

 colored felspar, and green mica, and in this rock were imbedded portions 

 of a semi-transparent, nearly white, felspar of a rhomboidal form, giving 

 to the mass a porphyritic structure. Numerous detached hills occur in 

 this neighbourhood. They are all very low — some exhibiting the above 

 described appearance of globular heaps piled upon each other — others are 

 smooth and conical, while others are peaked.
