Eighty ladies and gentlemen proceeded in reserved carriages 

 by the 2 p.m. train to Aldgate, and were then, by the courtesy 

 of Mr. A. Gr. Pendleton, the Traffic Manager, sent on to 

 Ambleside by a special engine. Here they were met by 

 Mr. Guest, of Balhaunah, who had consented to take the lead. 

 Following the Onkaparinga, a large red-gum tree was pointed out 

 by Mr. Guest as one of the largest, if not the largest gum tree in 

 the district. It was estimated to be 150 feet high, and the stem 

 25 feet in girth. In one of the main forks of the branches,

 lucidus, Goodenia ovata, Hydrocotyle vulgaris, H. asiatica, 

 Cladium glomeratum, the Maiden Hair fern (Adiantum 

 sethiopicum), and Potentilla anserina, hitherto not known in
