8 ■ Anniversary Address. 



occurring as they do in rocks whicli are so denominated ; and in 

 some cases (I may add) in true lava of modern volcanos. 



But, before I go further into this question, I must digress, in 

 order to explain, that though Diamond is thus associated, on the 

 Cudgegong and on the Macquarie, as at Suttor's Bar, yet there 

 are in my knowledge hundreds of spots throughout the length 

 and breadth of Australia, where the same gems are found in as 

 great abundance, often of much larger proportions, with or 

 without gold and without a trace of the existence of Diamond. 

 I have found them myself in this way in a variety of places in 

 this and the neighbouring colonies, in an area which I do not 

 exaggerate, when I call it a hundred thousand square miles ; and 

 within the last year I have recei^ved thousands of such gems 

 from correspondents and visitors who have consulted me, without 

 finding among them more than a few^ Diamonds and but ten 

 independent of the present produce from Two Mile Elat and 

 Suttor's Bar. 



Thx)se ten were found not far from Bingera, and are the first 

 fruits of a new locality. They were accompanied by zircon, 

 jarger than any found with Diamonds on the Cudgegong, but 

 also with very small crystallisations of the same mineral and 

 quartz. The friend to whom I am indebted for the examination 

 of these Diamonds, is encouraging a search for more. I may 

 add, that I have seen no Diamond from Cudgegong exactly 

 resembling those from Bingera. 



I have received also two Diamonds said to be found near 

 Kangaloon, on the Mittagong Eange; but, as many other 

 minerals which are probably not indigenous there, have also 

 been forwarded from the same neighbourhood, I have much 

 hesitation in accepting the statements made. 



A further announcement was made to me in 1870, of Diamonds 

 on the Darling, a few miles from Fort Bourke, but on examining 

 a large collection of the pebbles consigned to the Commercial 

 Banking Company as "Diamonds" and "precious stones," I 

 found that they were all varieties of silica [quartz, jasper, agate, 

 chalcedony,] with small highly polished fragments of fossil wood 

 and other drift.
