into the Bundair limestone. The transition may be studied in the 

 small outlying hills near Goorha, where, above the red and green shales 

 and marly beds, are 50 feet of limestone^ of which the layers near the 

 bottom are impure and shaly, but near the top thick-bedded (2-4 feet) 

 moderately pure and some very hard ; the prevailing tints are grey, 

 pink and yellowish, and here, as elsewhere in the Eewah district, the 

 rock contains thin bands and flattened nodules of black chert. The 

 passage is also observable in the Serangi stream just west of Omeri,

above which the massive blue limestone comes in. 



The section above the limestone (Sirboo shales, &c.,) may be taken 

 up in the Gusri stream, where the beds are seen at intervals. Rather 

 more than a mUe from the mouth, the Bundair limestone occurs of the 

 usual aspect, except that it is rather thinner-bedded than usual, dipping 

 west-30°-north at 5°. One hundred and fifty yards up stream are a few 

 feet of silicious green shale in beds of one or two inches thick ; then a few 

 feet more of blue compact limestone. One hundred yards beyond this are 

 greenish, earthy, sKghtly micaceous brittle shales passing above into red 

 shales, containing, higher up, thin bands of more or less calcareous rippled 

 sandstone. Beyond this the shale changes again to green with many 

 bands of sandstone and impure limestone, and about 200 yards east of 

 the Deccan road a 10 feet band of limestone comes in ; in the rising 

 ground to the east of Myhere some feet of sandstone occur, which 

 represent lower Bimdair sandstone, here reduced to a very small thickness. 

 The amount of shale between it and the limestone is greater here than 

 usual, as it generally does not exceed 20 or 30 feet, and hence has not 

 been invested with any special name.
