The Geo-physical Observations at Burrinjuck reservoir, 

 which were described in the paper read by Acting Professor 

 Cotton ia 1915, have been continued, but owing to pressure 

 of University business, he has not been able to work up the 

 results. However, sufficient observations have been made 

 to render it quite certain that movement of the earth's 

 crust has been taking place at the site of each of the 

 pendulums; the records also show earthquakes and earth 

 tides. 



The importance of molybdenum in the manufacture of 

 steel has been greatly increased as a result of the war. 

 This State is one of the principal sources of the supply of 

 molybdenite from which it is prepared, and recently the 

 Mines Department has issued a very important work on 

 the subject, prepared by Mr. E. C. Andrews, which deals 

 very exhaustively with the occurrence and working of the 

 deposits in this State. 



The Advisory Council of Science and Industry, established 

 about a year ago, has initiated many investigations on 

 subjects of considerable importance, the problems now 

 being dealt with, and for the solution of which special 

 committees have been appointed, are : — 1. Perro alloys ; 

 2. Manufacture of chemicals ; 3. Alunite ; 4. Posidonia 

 fibre; 5. The laws governing the mode of occurrence of 

 gold in quartz; 6. The tick pest in cattle; 7. The nodule 

 disease in cattle; 8. Yeasts and bread making; 9. The 

 standardization of physical apparatus; 10. The cultivation 

 of cotton and the problem of a mechanical cotton picker; 

 11. The prickly pear; 12. The brown coal of Victoria; 13. 

 The sheep fly pest; 14. Wheat selection and breeding; 15. 

 Indigenous grasses and salt bushes; 16. The standard for 

 alcoholometry; 17. Forestry and timber industries. 



Many members of the Society and other scientists of the 

 State are actively engaged in these investigations, and
