above the sea. In its vicinity are several subordinate peaks^ all of which 

 owe their elevation in a measure to the tilting of the beds caused by the 

 faults which bound the field. 



8rd. — Regarding the p^ts which occur on the south of the area, what 

 ^. little is known of the details of the caps which 



i^ats : crystalline hills ... 



capped by trap, lateiite, give them their peculiar character will be found 

 &c. 



on a following page. The principal are Neturhat 



3,600 feet; Lamti p^t 3,777 ; Gulgul pat, 3,823 feet; Jamira pat, and 



Mailan p4t, 4,024 feet. Besides these patSj from the contours of some 



of the hills near Balumath, I think it probable that they will be found 



to be capped with sandstone. The Madaffir hill. 

 Other capped hills. , 



near Toree, was found by Mr. Medlicott to be 



capped with sandstones, which appeared to him to be of Earakar age. 



North of the Hutar field, near Bansdih, the Chungah hill is capped by 



a curious arkose bed which forms a small plateau. 



As to the age of this rock, I am quite uncertain, owing to its very 

 local lithological characters. For the present it must remain unrelegated 

 to its position in the geological se'quence. 



Section 3. — Rivers. 



The principal rivers of our area are the Koel,^ the Aurunga, the 



Sukri and the Kunhur. The most remarkable 



Rivers afeord evidence feature exhibited in common by the Koel and 



01 great denudation. •' 



Kunhur is that their courses run north and south, 

 or at right angles to the valleys in which the coal-fields are situated, 

 thus indicating an enormous amount of denudation, since the direction 

 must have been determined when the valleys were filled up to the level 

 of the bounding ridges through which these rivers have cut deep 

 gorges. 



a I adopt this mode of spelling the name, as it more nearly, I believe, represents the 

 ordinary native pronunciation than any of the numerous other combinations of letters 

 which have been used by different writers, e, g., Coyle, Koyle, Coil, Koila and even Cel,
