40 HUGHES. SOUTH KARANPURA COAL-FIKLD. 



a study of the south Karanpiira, as an index of the true thickness of the 

 coal seams throug-hout the larger field. 



Commencing as usual our description from the eastj the first section 

 is seen in the Sirka river. 



Sirkd river. — Proceeding up this river^ from its junction with the 

 Damuda^ no coal appears in the hanks before we arrive nearly opposite 

 the village of Ajgarha. Two seams are there exposed. The lowest in 

 the series, the thicker of the two_, is 3 feet thick at its outcrop, and 

 dips at an angle of 35° to north-north-west. The axis of a synclinal 

 trending east and west passes a short distance north of the seam, and 

 the beds previously observed are repeated, but dipping at a lesser angle. 



For some way up the stream nothing but grits and . sandstones 

 occur, but from about the parallel of Tiingi to the boundary of the 

 field, three other beds of coal show. They are of small thickness and 

 unimportant in consequence. • 



MarangarJia river. — It appears from my notes that I did not 

 observe any seams in this river. The section is very imperfectly seen 

 owing to the sand. Iron-works are established on both banks, and 

 some of the ore is obtained from the bed of the river in an iron-stone 

 band, three-quarters of a mile north of the Agariah village. 



Near the entrance of the river into the field, a fault occurs inland 

 on the left bank. 



Bamudd river. — Although it would probably have been more in 

 place to have noticed this river hereafter, it contains but a few outcrops 

 of coal, and need only be somewhat briefly referred to. 



Nothing more than a thin bed of coaly shale half a mile south by 

 east of Dimwa, and a small bed of coal dipping 12° to south half a 

 mile south by west from Polamunda, are met with before the place of 

 junction of the Jarjarha river and the Damiida.
