AT NAGrUR, &c. 213 



Returning back to Nagpur by a middle route, between the granite 

 mounds of Woragaon and the range of hills on the north, a little hill and 

 a ridge of rock, running E. and W., is met with near Bishwamhher. 



The rock is of a cherty quartz and cellular, (No. ].*) and much inter- 

 mixed with a quartzy ore of manganese. The top of the ridge has the 

 exact appearance of the remains of a strong wall, and may be traced for a 

 considerable distance along the plain, and scarcely rising above it. 



The rocks were stratified and vertically disposed. Immediately north, 

 a part of the bank of the river is formed of massive Avhite quartz, and 

 inland, are traces of granite. 



On the Kanhdn, at Matni Mahoda, after passing east over the plain 

 from Nagpur, another dyke of contorted gneiss is met with, exactly simi- 

 lar to that of Nayakund ; it is here accompanied by cellular iron clay — The 

 extent of the gneiss beyond this, I am not able to mention ; but it proceeds 

 beyond limuUra, and my belief is that it forms part of a great granitic 

 formation, meeting by the way of the Ldnji hills and Retenpur, at 

 liamgerh, the great granitic range which sweeps round by Balasore and 

 Cuttack, to the Coromandel Coast. 



Near Komta, under the Ldnji mountains, are hills of red ochre of 

 good quality ; and in one of the nullahs running from that direction into 

 the Wi/ne Ganga, gold dust was found, samples of which, and the extract- 

 ed metal, I had the honor to forward to the late Dr. Abel, for the inspec- 

 tion of this Committee.
