Etone Implements in lateritic formations. 11 



and various other places. At the six places named Imple- 

 ments have been extracted from the solid rock. Of these 

 some were in very good condition, others considerably- 

 weathered. The latter seemed made of a less than usually- 

 compact variety of quartzite which has been most affected 

 where the laterite acquired a glazed surface. 



Many others also belonging to all the classes which are 

 described further ©n were found scattered over the surface, 

 having been weathered out of the laterite rock. 



The formation in which the Implements occur at Kircum- 

 baddy(l) in the Soornamookey valley is a bed of laterite 

 with pebbles of quartzite resting on decayed gneiss. 



I am indebted to Mr. W. R. Robinson, C. E. of the Madras 

 Railway for the following section of the Kircumbaddy plain, 

 and particulars of the occurrence of the Implements, 



Laterite including a bed of ) 



pebbles.... ) 



Decayed gneiss.. 10 feet. 



Gneiss 



The Implements occur in the laterite at a depth of from 

 to 3 feet below the surface which is the position of the 

 pebble bed As in many other places further south, Imple- 



Arconum Junction.,) The " Celt?' appeared from its position to have 

 been swept down the slope from the Corumbur rings fey heavy rains. 



A couple of hundred yards eastward I picked mp a good oval Imple- 

 ment of small size from among the debris of a bed of laterite conglome- 

 rate. 



About a mile further N. E. lies a curious circular encampment with 

 a, double line of eircumvallation thrown up on the side of the low hill — 

 which is there capped with quartzite shingles derived from the weathering 

 of the coarse lateritic conglomerate which there 'contains the Implements. 

 This interesting encampment is said by the country people to be the 

 work of the " Corumbur Rajak.*' Near the " Red Hills" tanks the 

 lateritic conglomerate, which further north contains many Implements, has 

 been quarried and used in the construction of stone circles and Kistvaens. 



It would be very interesting if a chipped implement could be found ha 

 one of the blocks forming these " Celtic" burying places. 



(1) Note. — Kircumbaddy is close to the Tripetty Station on the N, 

 W. branch of the Madras Railway, but fully 5 miles E, from Tripetty towa.
