4 inches of Coal ; 

 A layer of carbonaceous shale ; 

 Brown fine grained sandstone ; 



Massive beds of grit and sandstone free from argillaceous matter. 

 These beds are all so irregularly bedded that it would only mis- 

 lead to give to each a measured thickness : the

feet. 



Near the fault they seem slightly tilted up, and dip at low angles to 

 the south. This dip however, soon vanishes, and at no great distance up 

 the stream it is reversed ; above, the beds roll in gentle undulations from 

 north to south. 



Ascending the stream they appear here and there, just above the level 

 of the water, but are, for the most part, covered 

 by the massive thick-bedded grit and sandstone 

 mentioned in the above list ; they are, when seen, earthy sandstones, and 

 sandy shales, with carbonaceous partings and occasionally a thread of 

 coal, and the detailed section given very well describes the general char- 

 acters of the little group as here exposed. 



These are lithologically somewhat like the shales of the Mahanuddi,

identical with, the fossils found in the similar

 mains is the same, and, as a group, they contrast strongly with the flora 

 of the lower Damudas. There, as at Jubbulpore, none of the beds of 

 this latter division are found.
