red earthy, above more or less hard and silieious, the prevailing color 

 being a greenish grey. The Jheeree shales are less regularly bedded,, 

 softer, and mixed up with numerous layers of soft earthy sandstone. 

 To the east, however, where the intermediate sandstone is wanting, no 

 line can be drawn between them ; the passage from the Punna group to 

 the sandstone above is seen in the spur west of Sohagi ghit. Above the 

 mass of the Punna shales there is a blank of 12 ft. and then —

Tlie lower Rewah sandstone is absent in the extreme east^ and is 

 first observed in the outliers south-east of Burokur Khas, where, although 

 less than ten feet thick, it is apparent as a dark line at a uniform level 

 round all the hills. Near Sohagi ghat this rock is 25 feet thick 

 occurring in fine massive beds, hard, and often more or less vitrified. 

 The frequency of pebbles and sometimes smaU clay-galls is characteristic. 

 About the debouchure of the Tonse, where this sandstone is sunk to the 

 foot of the scarp, it covers a considerable area. 



The junction of this sandstone with the shales above it is sharply 

 marked. Thus at Ginga hill resting immediately on the former is 

 120 feet of rather irregularly-bedded shale, greatly cut up by small 

 jointing; of yellowish-brown and green colors, the latter variety com- 

 posed of fine green clay with a slightly greasy feel and conchoidal 

 fracture. The other beds are arenaceous, sometimes almost sandstone 

 and layers fully deserving this title are not uncommon. This 

 lower portion of the Jheerees is everywhere pretty much the
