at. the lowest levels and within reach of present floods) occurs on the high 

 hank of the river between Gondianur (Gondianoor) and Chennur^ seven 

 miles east of the last-named locality. North-east of Chennur the shing-le 

 bed must be fully 80 feet above the river bed, and 40 or 50 above the 

 highest floods now seen. No chert shingle was seen further east than 

 Koankal. A large spread of very similar shingle was observed (but not 

 visited) covering the high ground between Konechupli and Kurrikihulli 

 on the right bank of the river opposite Gondianur. 



Above the right bank of the Bhima river, beds of shingle similar 



to that iust mentioned and containing g-rey chert 



Of the Bhima. »o j ^ 



were observed at two places; between Nellawadugi 



and Naikal (Nykal) to the west of the Great Indian Peninsula Railway 

 Station at Yadghir (Yedageery), and again at Kumanur (Koomunoor) nine 

 miles further south-east. The chert in both cases is associated with quartz, 

 quartzite and gneissic pebbles. This high-level gravel seems to have 

 extended across the space between the two rivers, for a considerable quan- 

 tity of it occurs south of Wudigera, about half-way between the last- 

 named gravel locality on the Bhima and Kumanur and Konkal (Koankul) 

 on the Krishna also named above. 



The chert is very like that forming a bed at Shellugi near Talikot, 

 and described above (p. 198) . It is grey-mottled when freshly broken, and 

 weathers with a yellowish crust. The Shellugi chert bed is of intertrap- 

 pean age and agrees further with the chert of the gravel beds in showing 

 no organic remains imbedded in it. 



On the Tungabhadra river, but very little of the banks of which was 



examined, one very well marked g-ravel bed was 

 Of the Tungabhadra. "^ ^ 



observed at Cachapur near the southern end of the 

 great railway bridge. This gravel consists of quartz with some 

 quartzite and banded red jasper, and closely resembles the gravel now seen 

 in the river bed, but it lies at an elevation of fully 80 feet above the 

 present bed and far above the highest level now attained by floods.
