GEOLOGY OF THE COUNTRY. 91 



proportion of quartz, both as an ingredient in the compound rock and in 

 an unmixed form, is a very striking feature in the geology of this portion 

 of India, and one which ought not to be lost sight of. I shall take the 

 first opportunity of forwarding to the Asiatic Society specimens of the 

 rocks found in this district, which, I trust, will bear me out in the opinion 

 which I have stated. In Captain Stewart's account of the strata be- 

 tween Sarocla and Mhow, no mention is made of any overlying rocks on 

 the west side of the great formation, neither does the succession of rocks 

 laid down by Captain Dangerfield, appear to have been observed by 

 him. 



By the above remarks, I do not wish to detract from the well earn- 

 ed merit of Captain Dangerfield. We are indebted to him for much 

 very valuable information, but to make a perfectly correct geological map 

 of this part of the country would require years of minute investigation, 

 and in a climate like this could scarcely be effected by one individual — 

 too much praise cannot be given him for what he has done. 



Proceeding in the usual direction, we reach the village of Pit, in 

 the Diingerpur district, which stands eight miles distant from the last. 

 Immediately on leaving camp, the country became exceedingly broken 

 and uneven, and numerous small rounded hills were seen exhibiting at their 

 surface the vertical strata — quartz rock was still observed, but clay slate 

 was the preponderating mineral. In a well near camp, in a low situa- 

 tion, clay slate was also seen. The clay slate was, in some situations, of 

 a quartzose nature, and in others it approached to chlorite slate. 



Ten miles distant from Pit stands the BInl Pal of Ghdlah — for 

 the first three or four miles the country was exactly similar to that just 

 described, the jungle then became thicker, the country more broken and 



rugged,
