33 FOOTE: GEOLOGY OF THE BFLLARY DISTRICT. 



For convenience of description, the crystalline area may be treated 



of in seven quasi-natural subdivisions, which

the map and which will be considered in succes- 

 sion from west to east. They are the following : — 



i. The Harapanalialli-Uchingi Drug Subdivision, which lies 

 between the Dharwar-Shimoga band and the Mallapan 

 gudda (Dambal-Chiknayakanhalli) band of the Dharwar 

 rocks. 

 2 The Kudligi-Raya Drug Subdivision, lying between the Malla- 

 pan gudda (Dambal-Chiknayakanhalli band) and Sandur 

 bands of Dharwars, and extending south-eastward from the 

 Tungabhadra to the Mysore frontier. 



3. The Hirahal Subdivision — a very small area lying between 



the southern part of the Sandur band and the Copper Moun- 

 tain range, and bounded on the south by Mysore territory and 

 the great cotton soil plain of the Haggari Valley. 



4. The Hospet Subdivision, which lies between the northern part 



of the Sandur band of Dharwars and the northern part of the 

 Copper Mountain range and theKampli patch of the Dharwars, 

 and is bounded on the north-west by the Tungabhadra river. 



5. The Bellary Subdivision, between the Copper Mountain band 



and the Haggari river. 



6. The Alur Subdivision, between the Haggari river and the 



western base of the Adoni line of granite hills. 



7. The Adoni Subdivision, which includes the north-eastern 



extremity of the district from the Adoni hills (inclusive) to 

 the Tungabhadra, 30 miles to the north-east. 

 (1.) The Harapanahalli-Uchingi Subdivision. — The northern part 

 of this band, which is its narrowest part, is an open rolling plain, 

 chiefly covered with cotton soil and showing very few outcrops of rock, 

 except in the bed and bank of the Tungabhadra, which are rocky. 

 As the band widens southward into the Harapanahalli Valley it be 

 comes more broken in character, and numerous hills, from one hundred 

 to three or four hundred feet high, arise, due to the superior hardness
