up, distinctly show by their position and present 



condition that they must have sunk down in situ as the soft shaley sand- 

 stones were gradually removed from under them. Both these examples 

 occur in the Agani (Uguni) valley to the north-west-by-west of Sorapur. 

 The first and most important in size occurs about two miles south-east 

 of Agani. It occurs in the form of a low hillock 80 to 100 feet in height, 

 and about three quarters of a mile in length. In width it tapers from about 

 300 yards at the west end to a mere point, dying away under the regur 

 at the east end. This hillock is very bare of vegetation, and is seen to 

 consist of nothing but broken limestone fragments, among which it is 

 possible here and there to distinguish traces o£ the bedding formerly exist- 

 ing, but the general mass of broken slabs is in a state of perfect confusion. 

 At the west end the limestone rests apparently on granitoid gneiss ; 

 the actual contact is not exposed, but the two rocks occur in situ within 

 a few feet of one another. If, as there is every reason to believe, this 

 limestone was once continuous with the main plateau occurring beyond 

 the little hamlet of Sadab (Sudub), about three-fourths of a mile to the 

 west, the amount of shaley sandstone removed from below the limestone 

 must have been fully 60 to 70 feet in thickness. The usual base- 

 ment bed of the Bhima series, a pebble conglomerate, generally a hard 

 and compact rock, was probably of a softer character than usual at this 

 spot, and therefore removed by weathering, together with the friable 

 shaley sandstones, and thus the limestone rests now directly on the 

 gneiss. At the nearest spot at which the basement of the series is seen 

 (namely, about a mile west of Yeddipalle and three miles south-east-by- 

 east of this singular limestone hillock, which may be regarded as a " let- 

 down^^ outlier), it consists of a soft drab sandstone with small shaley 

 . bands in it.
