its presence being marked by small hills in which the hard conglomerate 



apj)ears, while all the surrounding strata have been denuded to a level 



surface. Then the middle group abuts against the fault till beyond 



Kerjaug, when the conglomerate comes in, being perhaps brought down 



by a North and South fault, and thence to the Westward only grits and 



conglomerates appear. They cover the whole Western half of the 



(so-called) Coal Field, with the exception of a few patches, and rise into 



ridges of hills of considerable elevation, some perhaps as high as 1,500 feet. 



It may be useful here to mention some of the more important faults of 



the Northern part of the field, to which allusions

Is^. The Keijang Fault, which forms the boundary of the Talcheer 

 field for about 35 miles, from Dolham in Rehrakol toTakua in Talcheer, 

 and which passes through Kerjang Hill. 



2nd. The Konjiri and Bodaberna Fault, branching from the above 

 near Kondaigula, West of Kerjang, and running nearly parallel to it for 

 many miles. This has been traced for nearly 28 mdes, from Kondaigula 

 to beyond the Brahmini Both these faults have a downthrow to the 

 South, together amounting to at least 2,000 feet, and probably to 

 considerably more. 



Zrd. The Dereng Fault, having a downthrow to the North, running 

 between the other two, and of much smaller size ; it appears to branch 

 from the Kerjang Fault near Porah, and extends to bej'ond Dereng 

 where it seems to die out. Its observed course is about 12 miles, the 

 downthrow probably never more than 200 to 300 feet. 



The Atgurh basin near Cuttack appears to be entirely occupied by 



grits, but too little time has yet been bestowed

relations, rendered difficult of comprehension as they are by dense 



impenetrable jungles and deep alluvium. Indeed, inasmuch as in the 



Talcheer field all the country occupied by the lower beds is level, while
