LATERITIC ROCKS. 91 



intermediate part is very probably equally fringed with the lateritic 

 gravel, but its whole surface is completely masked by thick cotton soil. 

 The occurrence of stone implements of • palseolithic type in the 

 Paleolithic stone im- laterite at Potelur in the Ramapatam area has 

 plements. already been mentioned (page 87). From the 



Kandukur area several very fine implements were obtained, to the east 

 and west of Kandukur itself and from Kondasamudram. Others were 

 found in the northernmost part of our area, in the fringing laterite at 

 Ippatam, close to the Kistna. A much larger number, however, was 

 obtained from some of the outlying unmapped shingle patches, the more 

 important of which will now be enumerated. They are especially 

 numerous in the valley of the Man-eru and its tributaries, where they 

 occur at intervals all up the course of the river, at levels above the recent 

 alluvium, e.g., at Nakanampetta, near Maregunta, around Velegunla 

 (Valegunlah), at Sallawarpalle, and at Kambaldinna (Cumbaldinna),also 

 at Kattakindapalle (Cuttakindapully), Mupad (Mopaud), Chintalpalem, 

 and Kothapalle, all on the south bank of the river ; nearly all these beds 

 yielded implements. 



Of the places on the north bank, two especially, Lingasamudram and 

 Comarapallem (Bompeadopaud of map), yielded many good implements, 

 though but little remained of the shingle beds they had been preserved 

 in. Further west still, implements were found associated with the 

 shingle beds near Irur (Eroor) and Iskapalle, and in the shingle bed which 

 lies like a talus at the eastern foot of the Vaimpad quartzite hills south 

 of Pamur. In parts these beds are so immensely coarse as quite to 

 deserve the appellation of " boulder gravels." They are generally more 

 or less ferruginous. 



A remarkable shingle deposit, in which, however, no implements 

 were found, occurs on the banks of the Chundi nullah, about 3| 

 miles east-by -north of Chundi village. The shingle, which is of gneissic 

 origin, is far too extensively developed to be attributed to the formative 

 power of the local stream. The ferruginous element is greatly wanting 

 in this case.
