Further south the whole country is occupied by alluvium. 



In the river bank at Bhoojpur below the superficial alluvium is a 

 gravelly incoherent deposit ( that might be con-

 tled brown and white, with much lime or lumps of decomposed kunkur, 

 beneath which it is red and earthy. 



North of this at Geylra a strong calcareous grit occurs among 

 faintly mottled, lumpy, earthy and sandy beds, un-

 Beraja is as follows : —

North of Beraja the traps rise into a strong east and west ridge with a 

 scarp to the north, and comprise various kinds of decomposing and solid 

 basaltic flows. 



Similar calcareous grits to those seen at Geylra re-appear at Bha- 

 raya to the east, their upper portion being coarsely
