ANNIVERSARY ADDRESS. LT 
3. GeoLoay.—In the Geological Department and School of 
Mines at the University of Sydney, research work has during the 
past year been directed chiefly to the radiolarian jaspers, cherts, 
and claystones of the Bingara, Barraba, Tamworth, and Jenolan 
Caves Districts. The results of these investigations by Professor 
David and the third year University students have already been 
communicated to the Linnean Society of New South Wales, and 
they prove that a large proportion of the Devonian rocks of New 
South Wales are composed of shells of Radiolaria. 
An examination with Mr. W. E. Abbott of the “ Burning 
Mountain” near Wingen, showed that there was conclusive 
evidence that the coal seam in which the fire is seated belongs to 
the Greta coal measures. There is proof that it has been burning 
for probably about one thousand years. The results of the study 
of the “Submerged Forest” at Shea’s Creek, and of the Sills at. 
Tamworth have already been communicated to this Society. A 
recent examination of a considerable area in South Australia, 
classed previously as Pre-Cambrian, has convinced Professor David 
and Mr. Walter Howchin that the rocks are of Lower Cambrian 
Age, as remains of Archceocyathine are abundant in a certain bed 
of limestone in this group. This will necessitate a complete re- 
classification of the older rocks of South Australia. ; 
In connection with the School of Mines’ students (or perhaps, 
to speak more correctly, students of the Department of Mining 
Engineering), at the University, it is a matter for congratulation 
both to Professor David and to Professor Warren, that Mr. J. A. 
Watt, ma. B.sc., has lately been appointed Geological Surveyor on 
the Staff of the Department of Mines in this Colony; Mr. T. 
Blatchford, .a., has obtained a similar appointment in West Aus- 
tralia, and Mr. E. S. Simpson, B.x., has received the position of 
Assayer and Analyst to the Geological Survey of the same colony. 
During 1896 a large amount of routine work was done by the 
Officers of the Geological Survey of New South Wales. Mr. 
Pittman, the Government Geologist, made an examination of the 
gold and diamond bearing deposit at Kangaloon ; what appears.
