In the Khunder nuddee and a small stream branching' from it, the 



following seams are exposed, the first, however, only

very partially ; its total thickness is not less ttian 



fifty-jfive feet, the coal appeared to be inferior. Higher up the stream 

 are two seams measuring four feet and twenty-five feet with a dip of 30° 

 to south-south east. Neither of these can be satisfactorily identified 

 with any of the seams in the stream which cuts a section only a few 

 hundred feet to the east. These last mentioned seams do not appear to 

 contain much good coal, they are made up almost entirely of stony 

 carbonaceous shale. 



Trap. A few fragments of rolled trap were observed 



lying in the bed of the stream, but none in situ. 



In the Damoodah, between the mouths of the Khunder and 

 Luganna nuddees, some beds of very Raniganj- 

 like character are seen in section. Geologically, 

 however, it is difficult to conceive how they could possibly belong 

 to the upper group, so that, in spite of their lithological character, we 

 have been obliged to regard them as Barakars. The occurrence of 

 similarly circumstanced rocks in the Bokaro field furnishes further 

 proof of the untrustworthy nature of lithological evidence alone, when 

 applied to the distinction of the several groups forming the Damuda 

 series.
