SOME FURTHER NOTES ON CHIPPED FLINTS 

 AT YENANGYOUNG, UPPER BURMA. 



By Rodway C. J. Swinhoe. 



In the last volume of * The Zoologist' (1902, p. 321) an account 

 was given of two visits, made by Lt.-Col. Nichols, R.A.M.C, and 

 myself to Yenangyoung, with the object of making further search 

 for traces of early man in that vicinity, in consequence of the in- 

 terest raised by papers published by Dr. Noetling on the occur- 

 rence of artificially chipped flints and a faceted bone, stated by him 

 to have been found in situ in a bed of ferruginous conglomerate 

 running round the Yenangyoung oil-field, and belonging to 

 Pliocene, if not Miocene, age. Our second visit resulted in the 

 discovery, practically at the place mentioned by Dr. Noetling, of 

 a number of flint chips, not, however, in the Tertiary bed, but 

 high above it, lying out on the surface of the plateau in such a 

 way as to prove that these chips are of much more recent date 

 than the Tertiary bed, and to have no connection with it. 



On that occasion, however, we had so little time left to con- 

 tinue our search after coming upon these flints, that we were 

 obliged to leave two important matters undetermined. The first 

 was where the lumps of chert found partially or wholly chipped 

 up came from, and the second was whether similarly chipped 

 flints were to be found at other points on the plateau, or were 

 confined to the neighbourhood of the place where Dr. Noetling 

 found his. 



These two matters have now been cleared up by a third visit 

 which I was able to make to Yenangyoung not long after the 

 publication of the previous paper in ' The Zoologist.' There is 

 at Yenangyoung a plateau gravel, mentioned by Dr. Noetling as 

 being peculiar in containing very large rounded stones, mostly 

 of quartz, which must have come from a great distance, and have 

 necessitated great carrying power to lay them down where they 

 now are, probably some hundreds of miles from where they 

 started.
