 dip steadily at low angles beneath the traps. 



In the neighbourhood of Eampur, several strong quartzose reefs

deposit occurs, which may have been the basal 

 portion of the trap series. It is formed of scoriaceous lumps of trap, 

 differing in texture, mixed with sand, clay, and gravel, the whole appa- 

 rently cemented by zeolitic infiltrations. 



The stratified traps south of this place show another strong escarp- 

 ment running in an east and west direction. 



Stratified traps. 



They consist generally of the usual gray amygda- 

 loid variety, with some purple bands, the weathered condition frequently 

 showing harder projecting lumps. Nearer to the base of the series 

 they contain chalcedony and zeolites, and compact basaltic flows were 

 more frequentlj' observed. All dip at low angles to the southward.
