<l dT Similar rocks of almost equal beauty are to be met with in 

 the beautiful cliffs of Ubbalagandi 1 , a little village lying 7 miles east- 

 south-east of Sandur, and just outside the state boundary. 



" e." On the little ghat path leading from the Ettinahalli bungalow 

 to the Forest Officer's bungalow on the top of the Donimali, the 

 plateau lying south of the Bhimagandi pass is another show of 

 beautiful jaspery rock, and both here and at Ubbalagandi is a more 

 highly siliceous variety of it in which the lamination is much less 

 distinct, and the red colour distributed in spots and clouds 

 through a whitish or more rarely bluish-grey mass. This too 

 would lend itself admirably to inlaid work. 



The green quartz found in the shingle scattered over the country 

 and Nemkal (Naimcul) south of the Nimcheri hills, and the green 

 quartzite occurring in the Dharwar bed close to Metra on the road 

 from Daroji to Kampli, are both susceptible of being utilized as very 

 pretty ornamental stones. 



Another valuable and important stone, as a building stone, is pot-

which has been used with excellent effect in the construction of 

 several temples in the extreme western talnqs. Notably in the temples 

 at Hira Kuravati and Nilgunda in Harappanahalli taluq and at Hira 

 Haddagalli in Huvina Haddagalli taluq. 



In all three cases the temples are largely and very beautifully 

 carved, and the carvings have generally resisted weather action 

 extremely well. 



The most important source of the potstone is the Nilgunda hill 

 and the band of similar rock which stretches

 An old disused quarry of good grey potstone occurs a mile south 

 of Angur (Ungoor) on the Tungabhadra, 4 miles to the west-north-

 Ubbalagandi gorge by which the Nari Nalla enters the Sandur valley.
