beds are the newer, as they are at the Pavulur end of the Budavada 

 section (see ante, page 69), hut with regard to the Kolakalur soft gritty 

 bed, I feel very doubtful what to think, though inclined to regard them 

 as newer than the hard beds. 



The Tangellamudi sandstones have been quarried for centuries pro- 

 bably, and great part of the bed removed in consequence. 1 The sand- 

 stones are best seen south-west of Tangellamudi and west of Shekur^ 

 where they can still be traced as a continuous bed, but much cut up by 

 jointing, especially where the purple colour prevails. The beds roll about 

 considerably, chiefly to the north-east and north-west. From 6 to 7 

 feet in thickness of rock is exposed, but the underlying beds are not seen 

 anywhere. The prevalent colours of the sandstone are reddish and 

 purplish-brown, ranging to positive purple with yellowish-buff stains. 

 Much quarrying is now going on, there being a large demand for the 

 stone for many purposes. 



In the Chebrolu inlier the sandstones are best seen in the pits near 



the old trigonometrical station, 3 miles north by

east of Chebrolu, and in those immediately north 



of the village. In the former from 9 to 10 feet of rock only is seen in 

 situ, and it is mostly of purple colour, with white spots ; but buff and pur- 

 ple mottled and purely buff colours are also to be found. The surface of 

 some beds is formed by a thin layer of small pebbles. 



The sandstone underlying the lateritic gravel close to Chebrolu is 

 a fairly massive compact gritty rock of purple, brown or reddish colour, 

 tolerably thick bedded, and the beds generally pretty level. From the 

 lie of the ground I infer that these hard sandstones overlie the friable 

 mottled purple (or red) and white sandstones exposed to the south of 

 Gundavaram village 1^ miles to the north-west of Chebrolu.

1 The Tangellamudi quarries appear to have been used by the Jains, for beautifully 

 carved specimens of the sandstones, evidently taken from an old Jain temple, have been built 

 into some of the walls, e. g., the northern gate, of the great hill fort of Kondavidu.
