for collected references on Diamonds in Australia, in Professor 
Liversidge’s paper, “ On Minerals of New South Wales f Trans. 
Roy. Soc. r N S. W., ix., p. 183, 1875; and W. B. Clarke’s “Ann. 
Address ,” 1872.] 
In other publications I have treated of them ; and since then 
the Bingera Diamond Fijfld has received careful attention from 
Professor Livcrsidge, who has described its condition accurately. 
Those found since .1800 have fully justified the heading of my 
notice published that year (“ Southern Gold .Fields ,” p. 272),— 
“ New South Wales a Diamond Counthy.” 
The Bev. Dr. Bleasdale, F.G-.S., lias published many valuable 
details of the Victorian gems. 
Looking to the Colony of New South Wales, we find that in 
more than one instance the present river channels have deepened 
since the drift first began to crowd their banks. [ have traced 
one of these drift streams, sometimes at great heights above the 
valleys, for more than 80 miles. In some places I have found 
upon the surface, as Strzelecki did in other parts, minerals 
(especially ores of copper, tin, and lead) which were at a great 
distance from their sources; and in two instances, that rare 
mineral, Molybdate of lead, of which no habitat has ever been vet 
found ; and about three years ago a lump of Sulphuret of anti¬ 
mony, weighing three pounds, and exhibiting surface evidence of 
its being a drifted substance, was disinterred from the superficial 
ironstone gravel of an unfrequented place on one of the heights 
of the north shore of Port Jackson. 
Some years since I reported on the occurrence of mercury in 
this Colony ; but my expectation of the discovery of a lode of 
Cinnabar has been disappointed. The Cinnabar occurs on the 
Cudgegong in drift lumps and pebbles, and is probably the result 
of springs, as in California. In New Zealand and in the neigh¬ 
bourhood of the Clarke Hirer, North Queensland, the same ore 
occurs in a similar way. About 1811 I received the first sample 
of quicksilver from the neighbourhood of the locality on Carwell 
Creek, on the Cudgegong, where the cinnabar is found. 1 pro¬ 
posed a full examination of that locality when I was in the 
neighbourhood in February, 1875; but the state of the weather 
was such as to preclude the possibility of doing so during my 
limited stay. But .1 was informed that the progress of the miue 
was satisfactory. 
As connected with the drifts may be mentioned the occurrence 
of gems of all kinds in all the rivers where auriferous deposits 
occur, and subsequent years have only served to abundantly con¬ 
firm my statement of 18G0 as to the general distribution of them 
in the gold-hearing districts.
