PART 2 .] 
Ball: Bismmpur Coal-field. 
37 
The Barakar faulted boundary leaving the Nakti north of Narkola is traceable south of 
Pakni to Karoti, where it is cut off. In several places along it the sandstones are highly 
indurated. 
R.ehr Bluer Section .—The Rehr river with its tributaries drains the south-western 
portion of the coal-field. 
The bounding fault of the south-west corner of the Barakars of the Bisrampiir area 
crosses the Rehr one mile north-east of Beltikri; the actual junction line is here covered, but 
Barakars and Takhirs are exposed at no great distance on either side. 
In the reach which strikes eastwards from Packira there is a trap dyke, whioh for a 
mile forms the northern bank of the river; at the other end it is 
Trap ’ flung by a small cross fault which brings it down to the southern 
bank. Besides this principal dyke there is a second, irregularly parallel to it, which traverses 
the sandstones for a short distance. 
In the next reach there is a coal-seam containing about 18 inches of fair coal. Dip 5° 
to north-east. Further on there is seam which is, I think, distinct 
from the last. It is inaccessible, being under a thick bed of sand¬ 
stone which overhangs a deep pool. It is probably from 1 o"-t 8" thick. Rather less 
than a mile beyond the junction with the Pasang there is a 
seam exposed in the bed of the Rehr, of which the measurable 
thickness is about 3 feet. It has a slight dip, which varies in direction between east and 
north-east. Most of the coal is fair, and a portion excellent. In the bed of the river beyond 
this, blocks of coal of considerable size—from what seam derived is uncertain—are abundant 
and of good quality. They may have been washed out of the seam just mentioned, or carried 
in from some of the seams in the Pasang. Beyond this seam, up to the boundary, the only 
rocks seen are coarse Barakar sandstones. 
Pasang Biver Section .—East of the Silphili Ghat, the section in the Pasang for about 
four miles exposes horizontal sandstones only. The same beds persisting throughout. 
West of the ghat the same sandstones continue for about four miles. In some places 
the river has cut for itself a deep channel. South of the 
deserted village of Kasalgiri there is a seam which at first, from 
the manner of weathering, appears to consist entirely of good coal. On close examination, 
however, more than half proves to be quite useless, and the remainder inferior earthy coal.

At the mouth of the Chapar river there is a seam, which, so far as it is exposed, 
consists of slaty carbonaceous shale, with portions coaly. Before 
Four seams. the mouth of the next northern tributary there is an inconsider¬ 
able seam of coaly shale, which has been locally tilted. Imme¬ 
diately after it the top of another seam is seen under water. Before reaching the mouth 
of the Arsotba tributary, the top of another seam, containing about 1 6 of coal, is seen 
at the water’s edge, and underlying the massive sandstone through which the channel is 
cut. This, or a distinct seam, is exposed in the reaches beyond the Arsotka stream; it 
contains 3' of coal and coaly shale, possibly more. 
Prom this up to the rnouth of the Karcka the rocks are covered. But a short distance 
beyond it a seam is imperfectly seen under the southern bank. 
Seam ' Possibly a continuation of the same is exposed at the mouth of
