7^ FOOTE : GEOLOGY OF THE BELLARY DISTRICT. 



there might well have been a much-frequented path there. There was 

 no conclusion to be arrived at then ; but, from a discovery I since made 

 at a pre-historic site in Cuddapah district, I think it is extremely- 

 probable that the preparation of palm toddy was known in very 

 early times. 



Between Kotekal and Emmiganur (Yemmi'ganoor), the country 

 rock, to use a mining term for convenience and brevity, is everywhere 

 granitoid with red soil on it. 



Four miles to the north-east of Emmiganur the rock to be seen is 



a typical porphyritic hornblendic granite of dark

grey colour, but weathering pink in parts. This 



is to be seen west of Timapur. A great show of granite is to be seen 

 on the plain around Garladinni (Gardinna of map). 



Granite is also to be seen in the bed of the 

 di^na nite at Nagala ' Tungabhadra, eastward of Nagaladinna (Naguf- 

 dinny). 



At the bend of the river, 3 miles east of Nagaladinna, is a show of 

 coarse hornblendic granite containing also some plates of biotite. A 

 very similar looking granite which occurs west of Timandodi (close 

 to the boundary between the Bellary and Kurnul districts) shows on 

 breaking no hornblende at all, only biotite (black mica) in large pro- 

 portion. 



The country along the Tungabhadra is covered almost everywhere 

 by black soil, which forms a band from 7 to 8 miles wide on the average. 

 The regur being, as a rule, very thick, outcrops of rock within its limits 

 are few and far between.

may be followed for fully two miles. There is nothing whatever to 



show the real age of this patch of schists, but they do not resemble 



the Dharwar schists. On the contrary, they have a decidedly
