120 I'OOTE : SOUTH MAHRATTA COUNTRY. 



five or six acres in extent, if so much, and of irregular form, and the 

 water which fills it in the rainy season has no visible outlet. On the 

 south side a spread of silicious limestone shelves down into the bed, but 

 on the other sides the banks are rather steep, and so are the channels 

 through which the water flowing from the Bilgi (Beelgee) quartzite plateau 

 enters the little lake. No information other than that to be gathered by- 

 actual observation was obtainable ; its apparently true lacustrine character 

 seemed to have attracted nobody ^s attention. 



Many of the cherty laminae show delicate, concentrically wavy dark 

 lines, which give the chert an appearance of con- 

 Concretionary struct- taining an organic structure. The same kind of 



ure or the chert. ^ ^ 



structure was observed in chert occupying a rela- 

 tively identical position on the south side of the Kaladgi basin, a little 

 north-westward of the Telluskod ford over the Malprabha and several 

 other places. 



A grey highly silicious limestone, also occuppng much the same 



Concretionary struct- horizon in the Kaladgi series in which this quasi- 



lu'e in limestone. ■ ,• i^i-iiiii 



organic concretionary structure is largely developed, 



covers a considerable extent of ground north of Temapur in the Mudhol 

 State, three miles north-west from the travellers^ bungalow at Panch- 

 gaum (Punsgaon) on the Kaladgi-Belgaum road. The organic appear- 

 ance is far stronger in the limestones than ia the cherts. 



Some three or four miles, eastward from Sanag Lake is another rather 



important show of limestones exposed chiefly in the 



Tolanmatti limestone, bed and banks of the Tolanmatti (Tolanmuttee) 



nullah. The beds here developed are grey, green and 



pinkish- white, banded and purple in color, the latter earthy in texture. 



Six miles east of Tolanmatti, at Tughhal (Tugehleehal), on the right 



bank of the Ghatprabha, are purplish-grey beds together with some 



others which are purple banded with bluish-white.
