of the Sandur State, but I did not see any boundary stones on the 

 ground by which to make sure of the exact position of the out- 

 crop. 



c. Gold. — This precious metal is at present known only to occur in 

 Gold washing near one rather limited area included in the limits of 

 Chiggateru. the jjallapan Betta band of the Dharwar series, 



where it is occasionally worked by a Jalagar residing at Chiggateru 

 in Harappanahalli taluq, who washes the sands of several small streams 

 flowing from the Jajkal Gudda, a great hill lying about 6 miles east- 

 north-east of Harappanahalli. The gold is in all probability derived 

 from several small reefs of good-looking bluish quartz which occur in 

 the schists forming the country rock in that quarter. In none of the 

 reefs was I able to detect free gold ; but the gold washed in my pres- 

 ence was sufficiently large in grain to show that some of the parent 

 rocks must have contained very distinctly visible inclusions of it. 



The best yield of gold was obtained from the Konganahosur 



In the Konganahosur stream > which flows ™rth-east from the north- 

 nullah, east flank of the Jajkal Gudda, where, however, 

 no reefs were seen ; but a good-sized one lying in the water-parting i \ 

 mile to the south of the washing place may well have been the source 

 whence the gold was derived. The second best yield was obtained from 

 a small stream west by north of Chiggateru not shown in the map. 

 The third came from a place called Changulu in the valley west of the 

 Jajkal Gudda. Washing in the Maithur stream lying half-way be- 

 tween Chiggateru and the Konganahosur stream yielded a surprising- 

 ly poor result in view of the position of the head-waters of the stream. 

 The Konganahosur gold is almost coarse enough for some of the 

 larger particles to deserve the appellation of " pepitas" (cucumber or 

 melon seeds), and the colour in all cases was very good.

Quartz Ireefs on the the flanks ° f J a J kal Gudda WaS adviSed b ? me

field ; but I believe it has not been carried out, so I would again 

 recommend it to be done.
