Notes on the occurrence of Stone Implements in North 

 Arcot District. By William King, Jun., B. A. Geolo- 



; gical Survey of India. 



After our discovery of the«e Implements in the Trivellore Taluq of the 

 Madras District, my attention was naturally directed to any area over, 

 [which might b:; spread debris-, or shingle, of quartzite at all- resembling; 

 that lying round the base of the Mlicoor hill-group, and fiwi which we 

 knew that the Triveilore Implements had in all probability been manufac- 

 tured. 



Tue country to the North West of Trivellore Taluq is frequently strewn 

 with much shingle, and it was not long before I found several speci- 

 mens : first, in several parts of the valley between the Nagloperum and 

 Naggery Hills in the Narnaverum Taluq of the N. Arcot District ; and 

 second, in the neighbourhood of Kirkumbady on the North West Line of 

 Bailway, about a mile or so north-west of Tripetty Station. 



A. Narnaverum Area. 



Over the first, which may be designated by the above name, worked 

 Stone Implements and other evidences of their manufacture were found 

 in three places not very far apart. 



Locality (1) is situated on a tract of low rising-ground which stretches 

 out from the eastern side of the Naggery Nose hill-mass. At about two 

 and a half miles S. S. W. of Cupedoo (ten miles along the new high road 

 running east from the Poo' oor Station, N. W. Line) there is a small old 

 pond or tank lying between some irregular and rocky trap dykes, and 

 among the gravel and earth dug out of the bed of this tank were three 

 Implements. They were associated with loose shingle and pebbles of 

 quartzite and a few flake -like fragments or splinters of stone. 



To the east of the tank, ou the road between Nonra and Cupedoo, I 

 saw occasional flakes of quartzite as well as an oval Implement which had 

 evidently been once embedded in the lateritic deposit now forming the 

 substratum; the implement was stained of a dark ferruginous color and 

 partly encrusted with ferruginous sand and gravel. This laf erite is a highly 

 ferruginous conglomerate and breccia, containing rounded and sub-angular 

 fragments of quartzite besides debris of other rocks. 



Locality (2). Again, at about three quarters of a mile north of Cupedoo, 

 I found fivef Implements (four or five others were picked up by my men) of 

 the longer pointed oval form, lying scattered round the edge of another 

 small shallow tank, together with much quartzite gravel, shingle, and some 



+1 . Tapering oval, with sharp end broken off, 



2. Small long oval. 



3. Broad tapering oval. 



4. Tapering oval.
