a ridge broken into three low hills ; between the north-western and 



central of which, at Joladarashi (Joladaraushy) 4^ 



Joladarashi Iron bed. ., , ,. TT .. , ., ,. ., 



miles east of the Haggan railway bridge, the old 



Bellary-Madras high road passes. On top of the third and lowest of 



the hills stands very conspicuously the village of Chelguriki (Chail- 



goorky). 



The ferruginous bed which forms the crest of the three hills is more 

 schistose than is often the case, and only in parts does it appear 

 quartzitic. The ironstone is mostly limonitic, and brownish instead 

 of reddish in colour. South-eastward of Chelguriki this ferruginous 

 ridge dies down, and all is hidden by cotton soil at the boundary 

 where the band enters the Anantapur district. In the Joladarashi hill, 

 the central one of the three, it is under and over-laid by brown argillites. 

 The argillites on the south side, i.e., underlying it, are on the hill west- 

 north-west of Joladarashi hill of pale buffy or drab colour, and contain a 

 number of very small haematitic beds only a few inches thick. The 

 main iron bed here, which appears to be the extension of the crest 

 bed on the Jaladara*shi hill E. S. E. of the village, has not the limonitic 

 character seen in the crest bed, but is haematitic and jaspery in 

 texture, poor in iron, and much contorted and vandyked on a small 

 scale. The general dip is doubtfully northward and there may 

 possibly bean inversion of the strata. 



A few miles further to the east-south-east a haematitic bed re- 

 appears, occupying a corresponding position in the band. 



The character of the western boundary of the Penner-Haggari band 

 Nature of the boun- * s > wner ever seen, that of a natural erosion boun- 

 daries - dary, but that of the eastern boundary appears 



to be a fault or series of faults causing the Dharwars to abut against 

 the old crystalline rocks. It cannot be positively asserted that the 

 general boundary line is formed by a number of faults, but it is a very 

 legitimate inference from the facts to be observed as the band is 

 followed up. That faults exist in places is, however, perfectly certain. 



All the dips seen are eastward and at right angles to the general 

 course of the band except in one solitary outcrop of schists in the bed
