 the sandstone above referred to, if any, was not traceable/' 



Cementation of the gravels into true conglomerates by deposition 



Kankar-cementedgra- ^^ carbonate of lime takes place on a large scale 



vels at Ballur, ^^ j^^^y ^^^,^^ ^f ^j^g Krishna, Bhima, and other 



rivers and streams of all sizes. One very marked example of this 

 is to be seen in the bed of the Krishna at Ballur (BuUoor) , six miles 

 north-west of Bilgi, in Kaladgi district. This local alluvial conglo- 

 merate is overlaid by a great thickness of clayey alluvium, chiefly con- 

 sisting of re-deposited black soil. The total thickness of the alluvium 

 here, and at the adjoining village of Hanchinal, exceeds 30 feet. None 

 of the wells at the last-mentioned village have pierced it. The water 

 which here filters through the alluvium is strongly brackish and con_ 

 sidered unwholesome by the villagers themselves. 



A similar conglomerate, forming in the Don river below Talikot and 



Kankar-cemented con- ^^11 lower down the stream, might also easily be 



glomerates on the D6n. mistaken for a pebble bed belonging to the Bhima 



series, did it not contain pebbles of the Talikot limestone which forms 



the youngest bed of that series. 



Another noteworthy instance of conglomerate, formed by cementa- 

 Anegwadi conglome- '^^^^n of gravel and shingle in a river bed by 

 ^^^^^' deposition of argillo-ferruginous matter, is to be 



seen a little below the ford over the Ghatprabha (crossed by the new 

 road from Goankop on the banks of the Malprabha to Sholapur) at 

 Anegwadi (Hangehdee). This local conglomerate yielded no organic 

 remains to determine its age, but, judged by its appearance, it is of 

 very recent formation. 



Two beds of kankar-cemented shingle, one in the Malprabha, 

 and the other in its tributary the Benni-halla, 



Implement-bearing 



gravels in the Malprabha yielded a large number of fine, well-shaped, and
