ANNIVERSARY ADDRESS. 25 



twenty minutes; and by a single wire five messages can be sent in 

 one direction. When we consider this, and the marvellous 

 applications of Electricity in the production of light, sound, heat, 

 and motive power, we stand amazed at the prospect of possible 

 discoveries yet to be made for our individual benefit and for the 

 unification of mankind. 



It augurs well for the future of this Colony that the Sydney 

 University has provided for efficient teaching in these subjects 

 and in Engineering. It is to the University, and also to such 

 Institutions as the Technical College that we look to the future 

 for well trained observers, whose scientific researches it will be 

 the object of this Society to record. 



Geology and Chemistry as applied to Mining and Agriculture 

 may well engage the attention of this Society. Investigation in 

 this direction will assuredly lead to results of much pecuniary 

 advantage to those whose occupation lies in the development of 

 two of the greatest industries of New South Wales. The 

 knowledge of the modes of occurrence of mineral deposits will 

 often afford a guide not only in the search for minerals, but also 

 in conducting mining operations, especially when faultings in the 

 strata or other difficulties occur. And the successful treatment 

 of the complex ores, which many of the more simple or oxidized 

 ores will pass into as the lodes are followed down, must depend 

 upon careful management under proper chemical and metallurgical 

 direction. Such management will no doubt also lead to the 

 utilization of the by-products and the consequent introduction of 

 new industries. It is satisfactory to see the announcement that, 

 with the view of aiding in the development of mining, the 

 Minister for Mines proposes to establish central testing works 

 where bulk samples of ore can be treated. The little book 

 " Mines and Minerals " lately published by two of our members, 

 Messrs. S. H. Cox and F. A. Ratte, affords valuable geological 

 instruction for miners.
