64< MALLET, VINDHYAN SERIES. 



In the Chula stream north of Adesar hill the bottom shales are well 

 exposed, being perfectly horizontal, in very thin laminae, very regularly 

 bedded. Where the rock is polished by water it exhibits a ribboned alter- 

 nation of red and yellowish- or greenish-white bands, the red predomi- 

 nating ; the highest beds seen are the lower part of the calcareous por- 

 tion. Two miles west of Kuttra ghdt at the foot of the scarp, the 

 shales are red, breaking up on the surface into small flakes. Interstra- 

 tified with them are thin yellowish calcareous sandy layers. Below this 

 is some 15 feet of a thin-bedded impure kind of limestone made up of 

 minute alternate layers of calcite and reddish silicious limestone. The 

 softer laminae weather away on the sm-face and give the rock a jagged 

 appearance. These sections of the Punna shales may be taken up 

 at Ginga hill where the lowest beds seen are the calcareous. The 

 following section is one observable in a small hill west of Ginga,
