34 HUGBES. KARANPtJRA COAL-FIEI.DS. 



we find also that the same sandstone is continuous around the gneiss. 

 A fault on one side or other of the inlier would have brought different 

 beds into contact with the gneiss. 



Ganespur river. — The next coal, west of the last locality that I 

 described, is in the Ganespur river, just at the mouth of the little 

 tributary north of the village of Ganespur. 



Going down the larger river, no more coal is seen until the beds 

 are reversed, and then three or four outcrops are visible. The two 

 highest beds in the series are small, but the third, which is about a 

 hundred feet lower in the series than the second,- is 2' %" and of tolerable 

 quality. Eighty feet lower than this is the fourth, measuring 1' 3" in 

 thickness. The whole of the sandstones, accompanying those . beds of 

 coal or coaly shale, are thin-bedded and bluish in colour. The upper 

 strata of the Raniganj are massive beds like those of the Dhardarwa 

 nala in the Bokaro field. 



Chati river. — The only other coal of which I know in this group 

 occurs in the Chati river, at the ghat between Hesalong and Gorialongar. 

 It is about eight inches thick and dips to tiie south at an angle of 15°. 



Respecting the flora of the Rauiganj group I have to repeat the 

 same story as of the Barakars. I failed to add any new species to our 

 collection of fossil plants. 



The Panchet Series. 



During the examination of the Damiida valley, the coal bearing 



rocks have always been the special object of attention, and the Panchets 



have never'been subjected to the same close scrutiny. Within the last 



year, however, the study of their relation to the rocks of the Sone and 



Central India areas has been the principal task of Mr. Medlicott, and 



that gentleman has satisfactorily shown that accepting the series as 



comprising both the upper and lower groups which are met with in the 



Baniganj field, it is found to stretch over an area of immense extent.
