were followed by a series of views of the salt lakes, and the 

 gathering, carting, and shipping of the salt. 



On June 21, 1916, Mr. William H. Dudley Le Souef, 

 C.M.Z.S., M.B.O.U., delivered a most interesting address 

 on "The Nidification of Australian Birds." The lecturer 

 showed a large series of splendid pictures, many of them 

 being works of art, showing the birds of Australia, their 

 nests and eggs, with specimen illustrations representing the 

 colouration of feathers, etc. 



Professor Edward H. Rennie, M.A. (Syd.), D.Sc. 

 (Lond. and Melb.), addressed the members on July 19, 1916, 

 on the subject of "Biology and Chemistry." The Professor 

 dealt very fully with the most recent discoveries in synthetic 

 chemistry, illustrating the principles on which the analysis 

 and synthesis of various organic chemical compounds had 

 been conducted. He also dealt briefly with the difficulties 

 surrounding the artificial production of protoplasm, and 

 referred to the recent theories of the chemical bases for the 

 nutrient values of certain food stuffs. 



On August 15, 1916, Mr. Edgar R. Waite, F.L.S., 

 Director' of the South Australian Museum, delivered a lecture 

 on "Deep-sea Dredging." Mr. Waite spoke of his personal 

 experiences in dredging and trawling off the coasts of New 

 Zealand, New South Wales, and South Australia. With the 

 aid of pictures and models the audience was taken over a 

 trawling vessel and shown the gear, the nets, and the crew 

 engaged in the work of trawling. The whole process was 

 explained, from the dropping of the net into the water to the 

 final emergence of the "cod end," filled with the finny spoils 

 of the deep sea. The experiences of the lecturer were vividly 

 described, and the slides from pictures taken by the lecturer 

 himself added interest to the address. 



Excursions. 



The excursions during the year were well attended, and 

 the thanks of the Committee are due to the gentlemen who 

 acted as leaders on the occasions of the various outings. 



On September 25, 1915, Mr. J. W. Mellor, R.A.O.U., 

 led a party of members through the scrub near Teatree 

 Gully, the chief work of the afternoon being the observation 

 of the birds of the district, in which direction the party was 

 very successful. A large number of flowers was also secured. 



The excursion of October 13, 1915, to Kuitpo Forest 

 Reserve was undertaken under the leadership of Mr. Walter
