Section in the Kehr. 
Gobri sections. 
The boundary between the Barakars and Takhirs is pretty well seen in the Behr north 
of the village of Pundih ; but in the surrounding country the 
rocks are completely obscured by alluvium, and I have been 
compelled to draw the boundary straight from point to point. It is probably somewhat less 
regular than is represented. 
Proceeding northwards from this junction down the bed of the Behr, there are greenish 
and yellow sandstones with some shales and flaggy beds, which are chiefly exposed at the 
salient points in the bed of the river. 
East of Sarnia 'there are some rather coarse sandstones, not altogether like Takhirs, but 
, , apparently geologically inseparable from other more typical rocks 
Sandstones what? . V 
of that senes. A short distance beyond, a nose of submetamor- 
phic-looldng quartzites and hornblendics strikes into the river. Prom the mouth of the 
Jumarpara stream northwards for about three miles no Takhirs are seen in the Behr, the rocks 
exposed being for the first mile hornblendics and slaty quartzites, with a west-north-west, 
east-south-east strike, changing to east and west. Nearly due west of Khopa V. S., coarse 
granites come in and continue up to and beyond Khopa. 
The Takhir boundary leaving the Behr close to the mouth of the Jumarpara stream 
strikes north-eastwards, passing round the village of Nouapara. 
In the streams north and south of Karonji the rocks are much covered; but where 
exposed, except at one spot below the village, they are clearly Takhirs. At that point there 
are some coarse sandstones, which I could not, as in the previous case, satisfactorily separate. 
In the Gobri river and its various tributaries which traverse the country between 
Chungari and Datrna the boundaries between the Takhirs and 
Barakars are very obscure. This is owing partly to the imper¬ 
fections of the sections, partly to the presence of rocks of indefinite character, colored like 
Takhirs, but lithologically resembling Barakars. 
There is an inlier of Barakars south of Dliora whose boundaries can only be approxi¬ 
mately represented. A reference to the map will explain the position better than any 
description. 
North and north-west from Nouapara the Takhir and metamorphic boundary runs with 
the Gobri, where it is very irregular and intricate. The river exposes granitic gneiss and 
Talchir rocks alternately. West-north-west of Kurkali, a belt of Talohirs, half a mile wide, 
occupies the low ground below Kaskela, and is seen in contact with the edges of the gneiss 
under the east bank of the Behr. 
Leaving the Gobri the boundary bends round Agina and Salka. At the latter place 
there is a remarkably fine boulder bed. The large masses of 
gneiss which have been washed out of it, when seen from a short 
Boulder beds. distance, look like rock in situ. A mile north of Kotia the 
Talchirs are cut off by tbe fault which bounds the field. 
A few small outlying patches of Takhirs occur in the metamorphic area which inter¬ 
venes between the north-west comer of the Bisrampur field and

Before proceeding to the description of the rocks exposed in the river sections, it will 
be well to say a few words on the localities where the rocks appear 
Itocks m high ground. high ground uncovered by alluvium. For the most part 
the rocks so exposed consist of coarse grits, and pebble beds which form bossy mounds or 
small hills.
