ADDRESSES, LECTURES, AND PAPERS. 



The practice of rendering technical advice through the medium 

 of conferences, lectures, and the presentation of papers at public 

 gatherings was somewhat curtailed during the year on account of 

 the war. Eepresentatives were assigned to attend only those meet- 

 ings and conferences of official bodies which were of State or Nation- 

 wide importance. A total of 68 lectures were delivered, as compared 

 with 149 during 1918.
