over the country in great rounded bosses, the 



tops of swelling masses which just peep through the more recent deposits 

 of lateritic and gravelly character. 



South of Bancoorah, veins of epidotic granite may be traced cutting 

 through the gneissose rocks, and heading nearly 

 east and west. And here and there, along the 

 western boundary of the district of Bancoorah, gneissose and hornblen- 

 dic rocks may be seen shewing just beneath the surface of the ferrugi- 

 nous gravel and laterite-clays which there prevail.

are well exposed ; there they are seen to be much

disturbed, and cut up by many irregular veins ot 



granite. This granite along the edges is highly micaceous, the mica 

 beincf in large crystalline masses of whitish colour. Felspar is also 

 abundant, and schorl locally so, but not equally distributed. The beds 

 of the gneiss strike nearly N. and S. dipping to the W. at 85°. On the 

 whole they are hornblendic, but are intercalated with many thin seams 

 of gneissose and granitoid character, and also some thicker beds of 

 hornblendic rocks. The granite veins cut across the beds, or occasion- 

 ally pass along the strike for a little way, in a most capricious way. 



These gneissose and hornblendic rocks continue into the district of 

 Puralia, beyond the limits of our map. 



The most easterly point at which these rocks crop out from beiieath 



the lateritic flats in Midnapore district, is near the

village of Sildah, about 30 miles west from Mid- 

 napore town. Here, grey and dark-grey micaceous schists with hard 

 gritty bands are seen in a stream close to the village. The gritty bands 

 shew the bedding of these slaty rocks well ; they dip to the east, at an 

 angle of about 40°: the slates abound vfiih andalusite in small crystals.
