think there is any promise of good coal being found in workable quantity. This seam has 
a more decided dip to the north-east than is common, the rocks being for the most part 
geam horizontal. Coal was met with south of the deserted village of 
Jhapra. The seam consists of carbonaceous shales, with thin 
layers of coal, one near the base measuring 6” ; the dip is 10° to south-east. 
The same seam is better seen in the Baheradol branch of the river; it is here seen to 
be of considerable size, and contains about 6| feet of fair coal. 
Some of the accompanying shales contain Glossopleris and other 
plant fossils. 
There are several other seams containing carbonaceous shale, with portions coaly. One is 
situated west of Jhapra and another west of Bhoja; the character 
of the latter hardly justifies the insertion of coal on the Topo¬ 
graphical Survey maps. 
Jhampi River Section. —In the Jhampi from Doin to its junction with the Mahan I 
„ only met with one seam of carbonaceous shale associated with

the Barakar sandstones. Some fragments of coal, however, indi¬ 
cated the presence of a seam in the area drained by the numerous small tributaries. 
Chengodri River Section. —Prom the character of this river and its banks it was 
geam absolutely impossible to follow it up closely. The only seam I 
met with, was one containing 1' 1" of coal which is situated at the 
junction with the Jhampi. 
Masan river Section. —As indicated on the Topographical Survey map there is coal in the 
Masan north-north-east of Jarhi; the total thickness of the seam is 
about 7', of which 2' is coal. It dips to north-east. From its more 
shaly and generally inferior character, I am inclined to think it is distinct from the seam about 
to be mentioned. This seam runs with the stream for a considerable distance, being last exposed 
about half a mile from the junction with the Mahan; it contains 
from 5 to 6 feet of coal, the upper portion of which is very fair. 
It has an unsteady dip to south-south-west, which never exceeds, and rarely attains 10°. 
This is the most promising seam in this part of the field. 
BanJci (Partabpur) River Section. —The boundary of the coal-field crosses the Banki 
about two miles north-north-west of Bardha. The section clearly shows it to he faulted; 
the edges of the sandstones are presented against the faces of some much tilted and 
disturbed slates and quartzites, the penetration of which by granite-veins and their 
s relations to the granitic gneissose rocks I shall allude to further 
on. At the junction on the western bank of the river a thin 
hand of 7" of coal underlies the topmost sandstone, and is itself underlaid by a greenish 
yellow sandstone, which I at first thought might be Talchir, but subsequently concluded 
to be Barakar. .

Prom this to the junction with the Mahan there are more or less horizontal sandstones. 
In the Daldali stream, nearly due north of Burdha, there is a seam of coaly and 
’• carbonaceous shale, which with its accompanying sandstones is 
(locally) upheaved to an angle of 45°; from this to the point 
where the stream passes into the Talchirs sandstones only are seen. 
Nalcti River Section. —The Nakti for a portion of its course runs with the faulted 
boundary of the Barakars, crossing and recrossing it frequently. 
The only rocks of this group which it exposes are sandstones. 
I* the Marata branch of the stream there is a small seam of coaly shale of no importance.
