by the continual dropping of water from the point of a 

 large stalactite. I therefore decided that these bays would 

 probably be well worth excavating. 



I may remark here that the rock-shelters in the neighbour- 

 hood of Lenggong are frequently visited, and sometimes 

 occupied for short periods, by the Negrito tribesmen who 

 frequent the locality. The two mentioned above, and others 

 which I examined later, showed traces of having been recently 

 used, among the remains left behind by the Negritos being 

 bamboo sleeping-platforms, sections of blow -pipes, burnt-out 

 fires, and the bones of soft turtles, bats and flying-foxes, which 

 had been roasted and consumed on the spot. The walls of 

 the Gua Kajang and the two bays were covered with the 

 names of Malay visitors written in Arabic cr Roman character, 

 while Chinese too had inscribed their signatures in their 

 native ideographs. On the walls of the left-hand bay, how- 

 ever, I found some patterns, drawn with charcoal, which were 

 obviously the work of Negritos, since they were exactly similar 

 to those which they engrave on their dart-quivers. Some 

 other very rude drawings should also, probably, be attributed 

 to these people. One of them, seemingly of an elephant 

 drawing a four-wheeled waggon, had points of interest; for the 

 artist, wishing to depict a vehicle of this kind, but either being 

 unable to visualise it as it would appear when viewed from the 

 side, or not being skilful enough to depict the parts of the 

 off-side wheels which would be seen, had sketched the two 

 near wheels and then added another couple, which were not 

 attached to the waggon at all, one being placed in front of 

 it, and the other behind. 



I came into contact with the Negritos on two occasions. 

 and once employed two men of the tribe to assist me in digging. 

 I was thus able to get them to talk to me about their habit of 

 using the caves, and to hear what they had to say with regard 

 to the specimens found. On their visiting me at Lenggong 

 Rest-House I also showed them three polished stone imple- 

 ments which I had purchased from Malays, who had found 

 them in the surface-soil of land planted with rice or rubber. 

 The Negritos called these b.du kareh, " thunder stones," which 

 is practically equivalent to the Malay name for them {haliliniar 

 or batu lintar). I do not think that they have any traditions 

 of their ancestors using anything of the kind. 



Having determined to excavate the left-hand bay, I started 

 work withafew coolies. I first of all had small trial pits sunk 

 here and there in the cave floor with the object of gaining some 

 idea of the nature of the deposits and of their thickness. I n every 

 pit fragments of bones and spiral fresh-water shells were found 

 in quantities. At the further end of the cave the deposit proved 

 to be only a few inches in depth, but towards the mouth it was 

 over four fret thick. About the middle, at a depth of two feet, 

 a hard stratum of shells and broken bits of bone cemented to- 

 gether with lime was encountered, with about another foot of
