thickness of from 500 to 600 feet, the series is made up of thick bedded 

 limestone, mostly pure, but in parts recurring (as it were) to the mixed 

 character above noticed. 



The minor calcareous bands were stated to affect a lenticular arrange- 

 ment, and it is found that this rule holds good on the great scale and 

 is true even in the case of this very great development of the limestone. 

 A spur of the hills, 600 feet high, is composed, as described, exclusively 

 of limestone, but the neighbouring spurs are found to present a mixed 

 character, and to show the limestone interstratified with many layers of 

 sandstone more or less calcareous. 



Not more than a mile from the limestone hill just noticed another 

 is found in which the calcareous bands are so few as to be almost over- 

 looked, and were it not for the transitional character noticed elsewhere, 

 it would be difficult to escape the conviction that a fault must have 

 brought into their present relative positions masses of rocks so very dis- 

 similar in lithological aspect. 



Futtipur village stands a few miles north-west 

 of the hill called Chatur Doria (see map).

Fig. 10 is a sketch of this hill as seen from the south west, looking 

 across the flat ground of the Talcheer and lower Damuda shales, from 

 which the hill rises to a height of 1200 feet. Ascending this hill from
