above the base of the series. In the deeper bore-holes at Pisgaon, their 

 thickness does not exceed 7 feet ; but at Parsora they swell into a bed of 

 14' # , and a few subordinate ones of 4 and 2 feet. The lowest bed 

 occurs 149 feet above the Barakars. In the Wiin hole, where they 

 were also cut, they are 145 feet above them. 



The town of Wiin stands upon a low ridge composed of sandstones 

 with ironstone bands, and also some red and pink argillaceous sand- 

 stones. The latter have been used in the construction of the new tahsil 

 erected within the last year, and they confer an attraction to its exterior, 

 which is not usually observable in buildings of its class. 



The dips are rather steeper in the neighbourhood of Wun than is 



found to be the case elsewhere. North of the 

 Wun. . nn 



town it is as much as 30°, and m the river 20°. 



The direction of strike twists slightly between Wun and Wagdara, but 

 it may be said to have a general line of south-east, north-west. 



The angle of dip decreases in the neighbourhood of Balar hill to 



„,,,.,, 12° and 8° : and the beds that were seen at Wun 



Balar mil. 



occupy a much wider area. On the north-east 

 side of the hill a coarse conglomerate occurs, containing pebbles of fine 

 red and buff-colored sandstone, probably Vindhyan. Red argillaceous 

 shales also occur, resembling the beds seen in the Chanda district around 

 Mangli ; and as they should not be much more than 400 feet above the 



coal measures, judging by the evidence of the Wrin 



til?bed.° n0fM " nglireP " hole > the horizon in the series allotted to tr^e 

 reptile-bed at Mangli is probably not too low. 

 A belt of alluvium surrounds the Kamthis of Balar hill and Wun, con- 

 cealing the continuity of their extension to the south, east, and west ; but 

 at Sirpur the red shales and typical sandstones of the series are again 

 seen — yellowish -brown f elspathic silicious sandstones with iron bands, and 

 argillaceous sandstones. Many of the latter are highly ferruginous, and 

 in places are almost crimson in tint. Small quantities of the brighter
