overlying tte Talchirs between Kfisipiir and Tetmatla on the left bank of the 
Godavari. Now, I am by no means prepared to assort that Barakars do not 
occur exposed at the surface, but in the absence of a single, section to which I can 
refer as yielding undoubted evidence of the pre.sence of Barakar strata, I have 
preferred to suppress the probable boundary lines which it would have been 
easy for me to indicate. The more so also, as perhaps an erroneous impression 
might have been conveyed respecting the possible existence of coal. 
Actual coal outcrops occur only in a few places. There are none in the small 
patch of Bardkars overlying the Talchirs north of Naogaon. But in the belt 
of rocks extending from Kairgura to Tandur and onward, there are several ex¬ 
posures of coal. 
The most northerly of these is one near Kairgura. The seam is seen in the 
„ , . right bank of the river that flows past the village

in the direction of Chirakunt, a tew yards north 
of the Tirani road ghat. Only a portion of its total thickness is visible.

The dip is a little east of north, at an angle of 15°. 
In a small stream, east of the main river and tributary to it, a much clearer 
section of the seam is exposed, and its entire thickness is 15 feet. Most of it 
is coal, and much of it of fair quality. The average composition is, according to 
an assay made by Mr. T. H. Turner, the Assistant Curator of our Museum,— 
Volatile matter (moisture 9’4 per cent.) .... 42'2 
Fixed carbon ....... 45'6 
Ash ........ 12-2 
1000 
Like the coal of the Wardha valley, and those of the several Goditvari fields, 
there is a large amount of moistui’e in this sample. The fixed carbon is some¬ 
what deficient, but the proportion of ash compares favorably with the standard for 
ordinary Barakar coals. Underlying the seam is sandstone identical with that 
which in the Wardha valley I have described as “nodular sandstone,” and which 
there always occupies a position immediately or almost immediately (argillaceous 
shale sometimes intervening) under tho coal. In the area that I am now 
describing, this kind of sandstone is constant in such sections as are exposed, 
and I would accept it as an almost sure sign of coal. 
There are no Talchirs sc-en below the Barakars, in the river or elsewhere near 
Kairgura, the former being overlapped by the latter, which here rest naturally 
upon the Vindhyans. 
Tho next outcrop of coal that I met with was about half-way between 
Coal outcrop between Kair- Kairgura and Abupiir. I look upon it as being the 
gfira and Abapur. extension of the Kairgura scam in a south-easterly 
direction. At the surface it shewed a diminished section, being only 5 feet,
