28 HUGHES. — KARANPURA COAL-FIELDS. 



rivers respectively, west of Koilera. They measure 3' and 8' and dip 

 to the north north-east. 



JJlaiu river* — One coal seam dipping- north north-east occm-s in 

 this stream. It is at a distance of about three-fourths of a mile from 

 the Hoharu. 



Chati river. — This river, one of the principal tributaries of the 

 Damudd; cuts through a few seams, but none that are of any great 

 importance. The one lowest in the series occurs at the junction of the 

 coal-measures and metamorphics. Its dip is 37°. It is of little value. 



The other seams are exposed about three-fouHhs of a mile from the 

 Damuda, and the following is the section (descending) : — ■ 



1. Coa^ seam ... ... ... 4' 5" 



^a^ Coal mixed ... ... 2' 1" 



(b) Grey arenaceous shale ... 8" 



(c) Coal shale ... ... 1' 8" 



2. Sandstone ... ... ... 3' 0" 



3. Coal seam (small). , " 



Seam No. 1 is seen in two places, an undulation of the strata 

 repeating it. 



MaJilan river. — Two seams occur near Kekrahi, dipping to east-south- 

 east. They are neither of them of any importance. 



Marmar river. — A seam exists west of the village of Marmar, 

 dipping between west north-west and north-west. This is the only bed 

 of coal worthy of mention in this neighbourhood. 



Lusingm river. — A seam crops out in the Lusingua river, a few 

 hundred yards west of its confluence with the Nagar stream. It is of 

 comparatively little value. 



* This river is not correctly mapped ; and I would here remark that the deliueation 

 of the tributary drainage system of the Hoharu south of Satpahrf hill by the old 

 Survey is so thoroughly untrustworthy that I have not attempted to accommodate my geo- 

 loo-ical lines to the rivers. I have taken as relative points the different villages ; and the 

 outcrops of coal which I have mapped will, with respect to them, he found to be pretty 

 correctly indicated.
