GENERAL GEOLOGY. 3 



North of this portion of the Damoodah under consideration, the 



watershed follows a line nearly coincident with 



the southern boundary of the Boharo field. On 



the south, the range of hills alluded to above constitutes the watershed 



which separates the tributaries of the Damoodah from those of the Cossye 



and Subunreekha. 



The jungle which covers the greater part of this area is low but 

 dense"^ and in some places only passable with great 

 ''^°''' difficulty. 



The villages, with the exception of those near the high roads, are 



very poor, many of them being mere clusters of 

 Villages. 



rude hovels surrounded with small patches of cul- 

 tivation, which are only by constant care kept free from the encroach- 

 ments of the surrounding jungle. 



The people are chiefly the lower castes of Hindoos with a rather 



large proportion of Sonthals and a sprinkling of 

 People.

I. — General Geology. 



Although by far the smallest of the Damoodah valley coal-fields, 



which have as yet been visited by the Geological 

 Character of coal-field. 



Survey of India, and though of no great promise 

 in an economic point of view, still the Ramgurh coal-field possesses geo- 

 logical features which in their bearing upon the general questions of the 

 mutual relations of the rocks composing the Damuda series are of con- 

 siderable interest. 



* Note. — The natural orders most abundantly represented in these jungles are Hhamnacece, 

 Apocynacece, Ehenaceoe, Anonacece, HupTiorhiacece, LorantJiacecB, Lylliracea, Comhretacea, 

 Sterculiacem, Dilleniacea and Fapilionacece. Besides these however almost a huhdi-ed 

 orders might be enumerated, amongst which the plants found here are dimible.
