60 HUGHES : SOUTHERN COAL-FIELDS OF REWAH GONDWANA BASIN. 



hood, it is only partly exposed, and, strange to say, not more than 3 feet 

 are visible in any section. I am quite prepared, however, to express the 

 conviction that it is probably 1 to 2 feet thicker. An analysis of a 

 Kdki Mala coal analy- sample from the Koki river outcrop did not give 

 favorable results, the fixed carbon being meagre, 

 and the ash abundant.

At Bichia the union of the Barnai and the Kewai takes place, and 

 then the latter river forms, for about 7 miles, the boundary between the 

 Korea and the Rewah States. West of Kerabahara it is confined to 

 Korea, and takes it rise between the upland peaks of Khoro and Dha 

 marpinga. In this remaining part of the field, watered by the Kewai 

 and its streams, there are not many seams of noteworthy size, but, as 

 usual, there are several of small dimensions, at Charwahi, Mouhari, Dugla, 

 Roji, Kerabahara, Chaton, Kaparia, and Pakriha. The principal expo- 

 . sure of coal is in a branch of the Jhiria, north 

 of Nerua. Its thickness is nothing striking, but 

 it looks good, and, as is almost always the case, the dip is easy. The 

 direction locally is to the south. Section —

Hestho River. — The next convenient division of the field is denoted 

 by the important drainage system of the Hestho. And just as the Son 

 is the paramount river in the Rewah State, so is the Hestho in the Kor^a 

 State. A few minor tributaries of the Hestho on its right bank just reach 

 into Rewah territory, but with these exceptions the Hestho, at all events 

 in its upper course, is truly a Korean river. It takes its rise in the heights
