granite). The hill is about 120 feet high. Immediately to the west 

 of it lies the new village of Guliem (Gooleum) built here after the 

 destruction of old Guliem by the great flood of Haggari in 1851. 



Leaving the Alur group, nearly all the outcrops noted to the 

 northward are of hornblendic granite, very rarely of gneiss, and this 

 holds good up to the extreme north end of the Alur sub-division 

 at the bend of the Harivanam nullah at Gubihal. 



7. The Adoni Sub-division, — This sub-division, as above delimited, 

 corresponds almost absolutely with the fiscal limits of the Adoni 

 taluq, which has one natural boundary — namely, the Tungabhadra— 

 along its whole northern side. The south-west boundary is an approx- 

 imately natural one— the Hira Harivanam nalla — while the south-east- 

 ern one is purely a fiscal one, separating it from Kurnul district. Only 

 the southern central part of the sub-division is hilly, and only in 

 the north-western part have a few scattered hills to be described ; 

 the extreme western, the northern, and north-eastern tracts are 

 quite devoid of hills. 



The hills may most of them be included in four groups : the Adoni 

 group, the Kamana Konda group, 11 miles north, the Kotakal group, 

 7 miles to the east, and the Emimganur group, 6 miles north-east 

 of Kotakal. 



The Adoni (properly Advani) group forms a very fine mass lying 

 north of the well-known town which gives it its

name, rising in a very bold scarp all but 700 feet 

 out of the plain, which itself lies 1,300 feet above sea level. The 

 highest part, which is covered by the ruins of the famous old hill fort, 

 lies immediately north of the town, and is well worth climbing for the 

 beautiful rock scenery close at hand and the fine panoramic views all 

 around. Even yet finer views are to be got from the high rocky 

 peak marked in the map as " station," which lies a mile to the east- 

 ward of the old fort and overlooks both it and the fine tank lying 

 between. 



The general colour of the very massive rock is grey, but in 

 parts it varies to pinkish grey and rich purple ; also to greenish, all
