92 eoote: geological structure oe THE EASTERN COAST. 



Considerable spreads of coarse gravel and shingle, the ruins as it 

 were of once existing beds, remain scattered over the gneiss to the north 

 and west of Maddalur (Muddaloor), in the valley of the Musi-eru. 



The most westerly point north of latitude 1 5° at which I found im- 

 plements in this region is Ramiapalle (Ramiahpully), 23 miles north- 

 west-by-north of Pamur, where considerable traces remain of a former 

 extensive development of lateritic beds in the shape of lateritic gravels 

 and dark red sandy clays. 



The surface of this tract, and indeed of the whole area drained by 

 the headwaters of the Pal-eru, is much covered and obscured by drifts of 

 bright red blown sand, which will be again referred to further on. 



• The last shingle bed to be mentioned occurs far north of all the 

 others at the village of Angulur Agranaram, 9 miles north of Vinu- 

 konda. Here a highly kankarry shingle of gneiss and quartzite 

 contains many rude, and some good, palaeolithic implements. 



A strong petrological resemblance exists between many of the 



non-ferruginous shingles and gravels just described,

beds) are not restricted to one particular tract, as are the southern ones., 

 and there is no reason to look upon them as in any way distinct from 

 the ferruginous beds, their mineral character only excepted. 



CHAPTER VII.— THE ALLUVIAL DEPOSITS. 



A very large area of alluvium lies within the limits of the tract 

 described in this memoir, as it includes the major part of the delta of 

 the great Kistna river. A minimum of time was available for the 

 alluvial deposits, so the examination they underwent was necessarily 

 quite cursory, but that was enough to give an idea of their general
