ously tinted with oxyde and hydrate of iron, and earthy chloritic schists. 

 Some of these schists are highly ferruginous. Farther south they pass 

 into the soft, talcose, and chloritic schists, west of Bangalore. Dykes 

 of basaltic greenstone, with beds of kunker, become more frequent as 

 Savanur is approached. The latter mineral fills up seams in the sub- 

 jacent rocks. 



The breadth of this band of soft schists extends easterly to the town 

 of Lakiswar, and from its northerly strike is evidently the prolongation 

 southerly of similar strata at Darwar already described. The dip at 

 Savanur was 40° easterly. 



Regur was first observed a little to the west of Bankapur ; near which 

 town the vegetation, peculiar to the Ghauts, terminates abruptly. 



From Lakiswar to Gudduck, granite, gneiss, and hornblende schist 

 are the prevalent rocks, and easterly to Bellary, in the ceded districts ; 

 but, as the geology of the country between Gudduck and Bellary, 

 has already been noticed, I shall not dwell farther upon the subject 

 here, but proceed at once on our easterly journey from Bellary towards 

 Cumbum. 



Bellary to Davankonda. — Gneiss is the principal rock between Bellary 

 and Davankonda, (a distance of fifty- three miles) basing a plain sloping 

 northerly towards the Tumbuddra, the surface of which (with a few 

 interruptions of reddish alluvial patches) is covered with a thick bed of 

 Regur. 



The Hogri river is crossed about twelve miles from Bellary, at the 

 village of Moka. It is here about 700 yards broad : its bed is now 

 (May) a dry extent of sand, and its banks barren with the heaps, and 

 hills of drifted sands. The prevailing westerly winds, cause the dunes 

 to march in an easterly direction, north of Auspari. The next march 

 from Moka, the granite is seen bursting through the gneiss in a low 

 ridge : oxydulated iron replacing the mica in grains and nests : east of 

 Auspari a large trap dyke is seen running ESE. 



Davankonda is situated at the base of one of the granitic outbursts, 

 on the borders of the Andhra kingdom. Telinghi is much mixed here 

 with the Canarese, or Karnata, of Bellary. 



The soil at the base of the granite is reddish, and sandy to a certain 

 distance round the base : at the edges of this upper layer the re'gur will 

 be found underlying it ; and below the re'gur either the gravel result-
