the trap, although dipping to the north, appears to do so at a lower angle 

 than the sandstone. A little to the west of this, on the slope of a high 

 trap hill called Mahakul, an intertrappean silicious bed of small thick- 

 ness, not more than 1 to 2 feet, was met with. 



Tlie same characters are exhibited throughout this patch of sand-

 horizontal. This is near the village of Chicholee, Almost at the very- 

 end of the sandstone, close to Nurha, a stream traverses the beds, and 

 exposes a somewhat peculiar section, in which trap, limestone and 

 sandstone alternate. Apparently some dykes or irregular intrusions, 

 perhaps accompanied by faulting, have penetrated and disturbed the 

 beds. The limestone has a brecciated appearance, and contains green 

 silicious bands. 



At Nurha the sandstone disappears beneath the traps. About 3 miles

 it is not quite clear if the top of the sedimentary beds here rises to the 

 surface, or whether the masses seen are merely fragments included in 

 the fault.
