exhibited by[Barakai's. Certain sandy ironstones and highly ferrugin- 

 ous slightly conglomeratic grits, which are seen in the sections of these 

 ridges on the slopes near Ookamand and Lohoor, made me for a time sup- 

 pose that these highlands were in part formed of Mahadevas. Finding, 

 however, that these ferruginous beds in some cases occur near the bottom 

 of the sections, being covered by typical Barakar conglomerates, I have 

 been compelled to class all the rocks which occur above the Talchirs on 

 the east side of the Koel as Barakars. The first regular cross-section 

 of these beds is obtained in the Dauri, where the 

 lowest Barakar bed at the southern end is a 

 highly^ ferruginous sandstone which rests upon the Talchirs north of 

 Saidope, as has been already indicated on a previous page when describing 

 the Talchir section. To it succeed normal Barakar sandstones and grits, 

 many of them, both here and in the Ghorassan river, being eroded so as 

 to form a great variety of fantastically shaped pot-holes, which sometimes, 

 by the breaking down, of the parting walls, have coalesced to form large 

 reservoirs, in which fish abound. In the north to south reach above 

 the Talchirs there occur, associated with the sandstones, four seams of 

 coal and one of carbonaceous shale, which average 

 only from 4''' to 6" in thickness. In the next reach 

 there is a larger seam of about 2' &' -, locally this dips to south-west, but 

 that is merely due to a roll, the general dip of the rocks being northwards. 



At the junction of the Ghorassan with the Dauri occurs the section 

 measured by Captain Sage { vide p. 4). The seam, which contains some 

 good coal% measures about 3' 6". Apparently it is exposed for some dis- 

 tance on the hills flanking the Ghorassan valley, 

 since fragments from it are found in the bed of 

 that river some distance up, though the seam is not itself exposed. The 

 dip is 5°, to west. Soon afterwards the beds turn round to a southerly 

 direction, and if they were more constant in character and thickness, we 

 should find a repetition of the just described section on this, the other.
