THE BAMUDA SERIES. 



33 



Rakam river. — I have applied this name to a little water-course 

 west of the village. There are in it three very thin beds of coaly shale 

 dipping south-south-east 10°. 



Gondd river. — The plotting by the old survey of this river is 

 so erroneous^ that I cannot map properly the position of the seams 

 which are exposed in its banks. But^ at the top of the group, and near 

 the ghat of the Gonda and Raham road, a thin bed of coal occurs. 

 East of the ghat and close to a jungle road there is a seam 5' 3" 

 thick,"^ dipping at an angle of 18° to east-south-east. The middle por- 

 tion is of tolerable quality. A little lower in the series is another seam 

 measuring 1' 0''. The dip of this is somewhat more southerly than the 

 other. Below this and still east of Gonda ghat there are two more 

 beds, each a foot or so in thickness. 



About two miles and a half west of the village of Gonda is an 

 ihlier of gneiss, against which coarse grained felspathic sandstones like 

 Barakars are deposited. I have placed them amongst the Eaniganj 

 group, notwithstanding their resemblance to the Barakars, for the 

 reason that we may have identical strata repeated when the conditions 

 under which they are formed are the same. I consider that the inlier of 

 gneiss is, in relation to the sandstones which we see in contact with it, 

 just the same as when those rocks were deposited. We have exposed 

 by denudation the original shore against which the Eaniganj sandstone 

 was deposited. Had there been any evidence of faulting around this 

 inlier, which might have altered its original relative position to the 

 sandstones, I would have hesitated, without further proof, to place these 

 sedimentary rocks in the Raniganj, group. On every side, the beds dip 

 away from the inlier without exhibiting any excess of disturbance, and 



* It would appear from my mapping as if this seam were unconformable to the overlying 

 Panchets. This arises fiom the relative positions of Rahaur and Sinda not being properly 

 indicated by the survey. .
