AT NAGPUR, &c. 209 



Proceeding from Ramttk to the west, the low range of broken hills 

 appear to be a confused mass of quartz boulders ; further on, a granite 

 country is entered upon, or rather a country formed from granite debris, 

 gravel of mica, felspar and quartz, composing the surface, with here and 

 there crumbling blocks of granite and gneiss ; but scarcely anything like 

 the live rock is to be seen till you arrive at the river Pesh, below the vil- 

 lage of Nayakund. Here, from under the high bank of the village, a dyke 

 of gneiss, perfectly vertical, crossed the river, and formed a dam, interrupt- 

 ing the navigation. The dyke was lost in the opposite bank. Being em- 

 ployed in breaking a channel through this rock, the whole of its interior 

 was laid open, and Dr. Voysey was so much struck with the contortions 

 it displayed, and its variety of appearance, that he visited this place, by 

 himself and with me, four or live times, and we have much to regret the 

 imperfect state in which he left his MS., which has deprived the Geology 

 of India of the remarks of this most acute and extensive observer. Few 

 will ever be found superior to him in intelligence, and none in close ob- 

 servance of facts ; and we can scarcely expect for some years, a person who, 

 combining these qualities, will enjoy his great opportunities of seeing the 

 formations of India throughout nearly its whole extent. 



Thie gneiss (No. 1. A) varied from granite to mica schist ; but the gra- 

 nite parts were veins, or rather imbedded masses of granite, for of most, 

 the whole extent could be observed to be included every where in the 

 gneiss. Quartz rock was frequently buried in it in the same manner, and 

 wherever the granite or quartz occurred, the grain of the main rock was 

 disturbed, and bent from its otherwise straight direction. 



The adjacent rock Avas a grey granite, composed chiefly of whitish 



felspar.
