34 ball: geology of the rajmehal hills. 



For about six hundred yards farther nothing is clearly seen, but at 

 the end of that distance sandstones and carbonaceous shales occur with 

 an irregular dip to north-west ; the whole section disclosed here does not 

 exceed a thickness of about seventy feet. At the next bend the dip has 

 a general northern direction. There is a considerable seam of carbona- 

 ceous and coaly shale, the edges of which have been brought into contact 

 with a bed of pebbly sandstone by a small slip. A little further on 

 there is a clear section with dip to east — 



1. Yellowish grey felspathic sandstone ... ... 20' 



2. Blue and black carbonaceous sbale, with four layers 



of from 1 to 2 inches of inferior coal ... 9' 



2a. Ditto ditto 2 coaly layers «. ... 6' 



35' 



The section is here again interrupted by a slight slip ; but the suc- 

 cession is simple, and can be resumed without any loss. The dip changes 

 from east round by north to west. 



At the base of the carbonaceous shales, &c. — 



Forward ... ... ... ... 35' 



3. Pinkish and grey shales somewhat false-bedded ... 10' 



4. Black carbonaceous shales with papery layers of coal 2' 10" 



5. Blue carbonaceous shale ... ... ... 2' 



6. Variegated sandstone (varies in thickness) ... 6' 3" 



7. Carbonaceous shale (no coal) dip 10° ... ... 8' 



8. Blue shales and sandy shales ... ... 17' 3" 



9. Sandstones ... ... ... ... 14' 



10. Pebble bed, dip W.-S.-W., about ... ... 18' 7" 



The above account has been purposely given in fuller detail than 

 would ordinarily be necessary, as the locality was formerly regarded 

 by Mr. Pontet as one of the most likely in the hills to produce coal, 

 All the points at which rocks appear have been mentioned above ; in none 

 of them is the coal other than of very poor description. Even were it 

 ascertained that there is a good seam which is at present obscured, there 

 would still be but little prospect of getting a constant supply of coal.
