[Upon Mr. Perry's map I have added some spots 

 around the head waters of the Yenesei to indicate that 

 agriculture with irrigation was carried on there in ancient 

 times (see E. H. Minns' " Scythians and Greeks," Cam- 

 bridge, 191 3, p. 246). The discussion of the interesting 

 type of culture associated with this practice in Siberia 

 must be reserved for some future occasion, for its con- 

 sideration involves some of the most complex problems 

 in the history of the Bronze Age. Mr. Perry's map at 

 once suggests the source of the Yenesei culture. 



F. W. Christian (" The Caroline Islands," London, 

 1899) gives an excellent account of the ancient terraces 

 in Yap, where so many instructive relics of the stone- 

 using people and their legends still persist. 



Since the map has been printed my colleague, 

 Professor Calder, has called my attention to the remark- 

 able remains of extensive terraced-cultivation and irriga- 

 tion at Kara Dagh in Asia Minor (see Sir William 

 Ramsay and Miss Gertrude Bell's, "The Thousand and 

 One Churches," London, 1909, p. 31 et seq.). 



In his previous communication' to the Society, Mr. 

 Ferry called attention to the intimate association between 

 the geographical distribution of ancient mines and mega- 

 lithic monuments, and incidentally referred to the con- 

 nection between these things and terraced-cultivation and 

 irrigation. I have met with a curious passage, quoted in 

 a memoir on "Commerce in Prehistoric Times," by Miss 

 Buckland, 2 which seems to throw some light upon this 

 matter. 



Referring to the introduction of metals and mega- 

 lithic architecture into Ireland she says : — " This change
