Apparently disconnected from this patch, Talohirs again crop out from beneath the Bara- 
kars in the bed of the Ebe below Ramesur, where there are green sandy shales with a low dip 
to north-east. Further east, in the village of Putrapali, sandstones come to the surface. To 
the north-east of that village, in heavy jungle, there is aridgeof pseudomorphio quartz which 
is not improbably connected with some faulting, hut I failed to discover its character owing to 
the laterite covering. South-east from Putrapali, along the boundary, small outcrops of shales 
are seen at various points ; and beyond Burimal, in the high ground, there are some consider¬ 
able lenticular masses of limestone included in the beds of silt. Further east from this, de¬ 
tailed examination was not continued, but Talchir rocks were observed at Bursipali and 
Kurimoul. 
Rajpur. —On the northern boundary of the above mentioned spur, Talchir rocks appear 
in the vicinity of Raj pur, especially in the Godadia near its junction with the Baisunder, where 
there is a short section of shales and boulder bed, the latter resting naturally on gneiss. In 
the Baisunder, too, close to the junction, there are some sandstones with a dip of 5° to the 
south-west. In the bed of the Ebe the rocks are for the most part concealed by sand; 
hut at Degam, on the western bank, there are short outcrops of shales and sandstones. 
To the south-east, at Siugaboga, some fine sandstones and shales are exposed, otherwise 
there are no other outcrops, and it would appear that at Chaltikra the Takhirs are completely 
overlapped by Barakar*. 
Garganbal. —Further north a narrow strip of Takhirs occurs on the boundary near 
Garganbal. The lowest bed is generally formed of arkose, as I found to be the case a little 
further north at Kosira on the Baisunder.* It rests naturally on the gneiss. 
Sambulpubi. —Passing now to the southern boundary of the field, a narrow strip of 
Talchirs is met with between the villages of Jamga and Laka. In some places, as to the 
south-west of Badpali, they dip away from the gneiss at a high angle. Sambalpuri is situated 
at about the centre of the area, and in its vicinity are the best sections. In some the 
beds dip at a high angle from the boundary. 
A little beyond Laka these rocks are overlapped by Barakars, which are again, them¬ 
selves, covered up by the upper sandstones. 
Still further west is the area which may be conveniently indicated by the name of the river. 
Kueket. On the east and north the Talchirs of this area are bounded by the upper sand¬ 
stones. Possibly the eastern junction may be faulted, but it has not yet been fully examined. 
On the west they are bounded by Barakars and on the south by gneiss. Close toLotan there 
is a fine boulder bed. 
HI-—Damuda Series— Barakar Group. 
In describing the Barakar rocks of this field, we have to deal with a number of detached 
or semi-detached areas. Those on the north have been partially or fully described in the 
already published report on the Baisunder and other river sections, and the area in the 
Mand valley, and thence westwards, has only been partially examined. As neither it nor the 
Baisunder section were visited during the past season, they will not be alluded to further 
here. 
Valley of the Ebe area.— Commencing on the extreme east of the known ..'exten¬ 
sion of this area, a narrow strip or spur of Barakar rocks is found iu the vicinity of Lupunga, 
where they are horizontal and much concealed by superficial deposits. Towards the north, 
the junction with metamorphics, as seen at Bomali, is quite natural, the Talchirs being com-
