DETAILED DESCRIPTIONS.

Bed below laterite. 



In many places this well marked Led has a distinct dip to the west ; 

 at Moonjhlao the dip is 5°, and this is about the average. 



This laterite throughout has the appearance of containing rounded 

 and subangular fragments of decomposed ferruginous trap. The mass 

 is a compact argillaceous and ferruginous rock, approaching claystone, 

 sometimes mottled, rather pisolitic in structure, and with the characteristic 

 glazed surface of laterite. The only rock anywhere 

 seen to intervene between it and the trap is a white 

 tufaceous looking argillaceous bed, resembling decomposed felspar, which 

 underlies it at Nerolee. 



In the Taptee are some instructive sections of the tertiary beds, but 

 Sections in Taptee ^^^J ^^^ "^^ continuous. Passing down the right 

 (north) bank of the river from Bhodan, very little 

 trap is seen, though it is in place a little way back 

 from the river's bank. About a mile from Bhodan, laterite is seen 

 in the bank dipping to the west, and just east of this, trap is in 

 place on the opposite (south) bank of the river. Below this nothing is 

 seen in the river bank for about half a mile farther, until, at the 

 mouth of a small stream called the Rhen, the following section is 

 seen : — (descending) :
