on "Noxious Weeds and other Introduced Plants," and by 

 Mr. R. E. Stanley on the "Basic Principles of Rock Classifi- 

 cation." 



At these meetings Exhibits of special interest in the 

 various branches of science have been submitted. 



Excursions. 



Thirteen excursions have been held during the year, and 

 as these were limited to Saturday afternoons the time at the 

 disposal of members restricted the area of operations to 

 within a few miles of the city. Much of the ground is re- 

 visited, and the spread of settlement is gradually adding to 

 the difficulty of finding fresh fields for investigation within 

 easy distance of the city. 



The first excursion for the year was to Gaudy's Gully, on 

 October 12. The gully is situated above Burnside, towards 

 Magill, and being unfrequented offers many advantages to 

 collectors. 



On October 26 the National Park, at Belair, was visited. 

 While it is gratifying to know that a small portion of the 

 Park has been set aside and fenced as a special reserve for 

 native flora, it is still hoped that the Park Commissioners will 

 arrange to have a larger portion of the unfrequented parts 

 fenced in so as to be free from molestation. 



On November 9, 10, and 11, a party visited the neighbour- 

 hood of Kangarilla and Dashwood's Gully, but no official re- 

 port was made or published of the excursion. 



On November 30 Bridgewater was visited and Cox Creek 

 traversed for some distance ; the country in this vicinity is 

 amongst the most picturesque in our hills. 



On December 14 a drive was undertaken to Norton Sum- 

 mit, via the Green Hill Road and Summertown. At various 

 points the excursionists alighted from the drag and revelled 

 in the luxuriant profusion of native flowers. This was the 

 last of the field excursions during the early summer months. 



On February 15 the members were asked to make a 

 marine excursion for dredging in the shallow waters of the 

 Port Adelaide river. This was the most popular fixture of 

 the year. The dredgings proved interesting and instructive. 



The usual Easter excursion was arranged to include a 

 visit to Yankalilla, but the means of travel to such a long 

 distance presented difficulties, and the official excursion was 

 abandoned. 



During the winter months excursions were made to 

 Blackwood on May 20, Largs Bay on May 30, National Park 

 on June 20, and Brighton on July 18.
