Diamonb. 
Diamonds were discovered in this Colony by Mr. Stutchbury, 
the Government Geologist, and by Mr. E. H. Hargraves, in the 
year 1851.1! The Rev. W. B. Clarke had many diamonds brought 
to him in 1859 and 1860.? 
Systematic search for diamonds was begun in 1869 on the 
Cudgegong River at Warburton, better known as Two-Mile-Flat. 
Some very fine stones were obtained here, but the industry was 
not a profitable one, and in 1890, the date of my visit to the 
locality, there was not a single man engaged in Diamond-mining. 
The few miners who, to this date, are working the Tertiary and 
Post-Tertiary drifts for gold, occasionally tind a good diamond. 
The geology of the Cudgegong Diamond-field has been described 
in detail by Messrs. Norman ‘Taylor and Thomson,* and later by 
Mr. Taylor in the Geological Magazine.* 
No stones hitherto found in Australia have surpassed the 
diamonds from this locality. The yield per load has been greater 
1 Liversidge—Minerals of New South Wales, p. 116. Mr. Stutchbury 
reported in 1851 that he saw a “‘ beautifully crystallized diamond from 
the Turon River.”—Papers Relative to Geological Surveys, New South 
Wales. Laid upon the Council Table 2nd December, 1851. The Report 
is dated “Camp near Burrondong, ne 18th, 1851,” and by an evident 
clerical error, is not included in the schedule prefixed to the papers.
