utterly hidden, and then, if a little outcrop does show in the dry bed of a 

 stream, the chances are ten to one that the rock is too much weathered 

 to be safely recognized : its original character can only be guessed 

 at. 



One of the chief shows of rock south-south-east of the Alur hills 

 Ram Dm*, occurs at Ram Drug (Ram Doorg), 1 1 miles north- 



west of Guntakul Junction, a fine bold sharp- 

 peaked hill, rising some 600 feet above the plain and 2,029 feet above 

 sea level. In the north spur, the rock is a fine grained grey granite cut 

 up by many veins of a younger granite, also by veins of a felsitic min- 

 eral, and it shows also much coating of joint surfaces with pistacite. 



The neighbouring hills of Naggaradoni, Sangala, Beldoni, and 

 Chippagiri are all granitoid, but without a special distinguishing fea- 

 ture. To the south of Chippagiri hornblendic granite shows near the 

 Bantanhal railway station. 



The hills at Chakibanda (Chaukibunda), those north of Virapur 



station and Karakal hill, rather further to the 

 Virapur station hills. 



north-west, form an extension of the Guddakal 



ridge in Guti taluq, of a generally highly felspathic rock which ranges 

 in appearance from a fine grained felsite, through a pink felspathic 

 gneiss to a rather coarse highly quartzose granite. Its texture is 

 very variable, and it is cut up by very ill-developed systems of joint- 

 ing, so that its blocky surfaces are remarkable for the shapelessness 

 of the blocks covering them, which produces an effect of great unti- 

 diness and shabbiness. 



Some 8 miles to the north by west of Karakal a low ridge of 

 coarse hornblendic (?) gneiss crops up close to 



Sindaball hill. 



the Tungabhadra at the village of Sindavalam 

 (Sindaball), an extension probably of the rocks near Chinta Kunta. 

 Sindaball hill, and a much higher very striking hill, two miles to the 

 north-east, are both omitted from the map. The latter shows a 

 highly felspathic variety of hornblendic granite. 



A little more than i| miles to the north-west of the latter rises a 

 New Guliem syenite small very steep-sided hill (not in the map),
