234 FOOTE : SOUTH MAHEATTA COUNTRY. 



It would have been very desirable in several instances to have mapped 

 these alluvial beds separately^ but it was found quite impossible to draw 

 any even approximately trustworthy boundary line between them and 

 the adjacent spreads of regur. This is due to the rain-wash masking 

 the surface of everything-. This remark applies especially to the allu- 

 vium on the banks of the long still reaches of the Krishna river, which, 

 in conjunction with the deep pools of water, completely obscures all the 

 older underlying rocks, and which for that reason it would have been 

 far more satisfactory to have mapped separately, if that had been 

 practicable. 



In some cases on the smaller rivers the alluvium is locally 



confined to a well-defined flat surrounded by higher

grounds, and no doubt can exist as to the extent 

 of the alluvium. Four well-marked cases of this kind were noted on 

 the Ghatprabha and its tributaries, and in each of these cases the 

 alluvial flat, or basin, was found to be situated just above a narrow gorge 

 through which the river had had to force its way. 



Two of these alluvial areas, formed by small rivers, occur near 

 Belgaum, and both occupy shallow valleys above what may be termed 

 the eastern edge of the ghat region. 



The one occurs along the course of the Markandeya (Markundee)

 cases the alluvium consists of a black-clay, a quasi-regur.
