ANNIVERSARY ADDRESS. 29 



also made an official examination of some of the West Australian 

 goldfields, giving particular attention to the telluride-bearing ore 

 bodies. 



Mr. J. E. Carne, Geological Surveyor, completed the examin- 

 ation of the country along the New South Wales- Victorian Border, 

 as far as the head of the Murray. This work though unsuccessful 

 from an economic point of view, was of great interest, as it proved 

 the occurrence of Lower Silurian graptolite-bearing slates and 

 Devonian fresh-water sandstones in new localities. An examin- 

 ation was also made of the Wolumla District, where the gold- 

 bearing rocks consist of impregnated patches of crushed granite 

 and sedimentary rocks. Some of the sedimentary rocks are of 

 Devonian age. Mr. Carne as well as reporting on other districts, 

 also prepared two reports on our mineral resources, dealing with 

 tungsten and chromium. 



Mr. T. B. Jaquet and Mr. J. A. Watt, Geological Surveyors, 

 made a complete examination of the Captain's Flat ore deposit, 

 and submitted a report dealing with it. Mr. Jaquet as well as 

 performing a considerable amount of routine work, also reported on 

 the Elsmore Valley deep tin lead and on the Port Macquarie Cobalt 

 Deposit. Here the cobalt occurs in serpentine and in the clay 

 formed by the decomposition of the serpentine. The ore occurs 

 in nests or pockets which are irregularly distributed. 



Mr. J. A. Watt, who was appointed during the year, made in 

 conjunction with Mr. Jacquet the examination of Captain's Flat 

 already referred to, and also reported on the supposed diamond- 

 bearing drift at Upper Tarlo. There the drift consisting of sand 

 and gravel occurs under basalt, and it was from a shaft sunk to 

 the bottom of the gravel that the diamond was said to have been 

 found. Gold also occurs in the drift. Mr. Watt also reported 

 on a deposit of iron ore at Carlo's Gap, and on the Nanima Creek 

 and Gooda gold-fields. 



Since Mr. Carne's discovery of Lower Silurian rocks on the 

 Victorian Border, slates of the same age (as proved by their con-
