whose uncanny cleverness in defending themselves was well 

 brought out. Sonic of the slides made by the speaker himself

Excursion, November 19, 1921. — A large party travelled 

 per charabanc through the hills to Cherryville, which was seen 

 at its best, the numerous cherry trees being loaded with the 

 glowing fruit. The winding roads, bordered with orchard trees 

 and stringybarks, the steep gullies, and the abundant native 

 flora made a charming picture. The botanical members secured 

 a good, many treasures from the scrublands of the hills.

 for assuring this. In the course of his address Mr. Waite made 

 the capital suggestion that the caissons at Glenelg, now re- 

 garded as mere debris of the abandoned breakwater, might 

 be used as material for erecting a marine aquarium at our 

 premier Avatering-place. This was only one point in a very 

 informative address. Mr. B. B. Beck followed with a descrip- 

 tion of various water plants, illustrating their different 

 modes of growth by living specimens, slides and episcope 

 views. Mr. H. M. Hale dealt with some forms of aquatic life. 

 His slides were fine examples of the photographic art. and his 

 1-ecture conveyed a great deal of information on this interest- 

 ing topic.
