duced in large quantities in the Chota-Nagpur plateau : 

 also from Thibet, the gold produced there being called 

 * ant-gold': and in Assam and northern Burma. The 

 rulers of Assam used formerly to require their subjects 

 to wash for gold during a certain number of days each 

 year. 



Three great centres of diamond-getting are reported 

 in India. The first constitutes the valleys of the 

 Godavari and Khrishna rivers ; the second is the Chota- 

 Nagpur region, and the third is in the Vindhya Hills. 

 Precious stones were found in various parts of southern 

 India and pearls were got from the Malabar coast and 

 from Ceylon. 



The distribution of megalithic structures in India 

 therefore corresponds with that of ancient gold-mining, 

 and the sources of pearls, diamonds and other precious 

 stones. This is clearly shown in the map {Map II.) 



The association between megalithic structures and 

 the early mining of certain forms of wealth serves to 

 throw a flood of light upon the cultural history of India, 

 and should serve as a basis for future research. The 

 support which is afforded for the conclusions suggested by 

 the European coincidences is precise and even startling 

 in its nature. Once again we see that the two general 

 distributions, mines and megalithic culture, agree one 

 with the other. But other considerations now force them- 

 selves into the argument. South India and Ceylon are 

 places where immense quantities of precious stones and 

 pearls were exported to the west. A great trade existed 

 in these things at the time when Dr. Elliot Smith and I 

 suppose that the great megalithic wave first set out from 

 Africa for the American coast, and a consideration of the 

 facts in India would lead to the association of precious 

 stones and pearls with megalithic structures. We are
