164 THE MINERALS OF NEW SOUTH WALES. 



On June 23rd, 1875, some articles and letters referring to the 

 discovery of gold appeared in the ParJces Gazette, in which it is 

 stated that Mr. John Phillips announced the discovery of gold in 

 1847. A letter, dated from Jermyn-street, 1 Cth July, 1 855, from Sir 

 Kod. Murchison to Sir Chas. Hotham, is cited, which states that 

 " Mr. Phillips is the person who first announced to me that he had 

 detected it (gold) in your government (1847). I so stated the 

 fact in my letter of 1848 to the Colonial Secretary, Lord Grey, 

 when I urged upon H. M. Government to take the initiative in 

 developing the auriferous resources of the region." 



To Mr. Hargraves in 1851 was reserved the satisfaction of 

 showing that goid existed in great quantities in various parts of 

 the Colony and how it could be readily obtained from alluvial 

 deposits by means of the cradle. 



Silver. 



Native Silver. 



Native silver does not appear to have been found in situ in 

 New South Wales. 



The Rev. W. B. Clarke mentions in his " Southern Gold 

 Fields," that silver has been met with in the Southern Districts in 

 two or three places in the form of small fragments and arborescent 

 crystals. The same author mentions finding a thin plate of flexible 

 silver having a sp. gr. of 10. 



Strzelecki found traces of silver in the western country in 1839. 



Silver glance. 



Chem. comp.: Sulphide of silver = Ag 2 S. Silver, 87*1; S, 12'9 = 

 100. Cubical system. 



This ore has been found with iron pyrites in quartz, also in lime- 

 stone on the Clarence River, and on the Manning River. At two 

 or three places near Bathurst, at Copper Hill on the western side, 

 and at Brownlea ; on the Page and Isis Rivers ; at Brunaby 

 Creek, county Argyle ; at Broulee, Moruya, with cobalt, zinc, 

 and iron ; Teesdale, Co. Bathurst ; Queanbeyan River, Burra 

 Creek, Yass River ; Buckinbah ; Tacking Point, Co. Macquarie ; 

 Borrowa Creek ; Crookwell River : with gold, lead, and zinc at 

 Gulgong ; with carbonate of lead at Peelwood ; with galena and 

 iron pyrites at Shellmalleer ; on the Molonglo River, near junction 

 with the Murrumbidgee, and at junction of Murrumbidgee Creek 

 with Mountain Creek. In nearly all cases the silver sulphide 

 occurs mixed more or less intimately with galena, so that properly 

 it should usually be termed argentiferous galena.
