EXHIBITS. 



Mr. J. H. Maiden, f.r.s., exhibited specimens of botanical 

 or historical interest with the following notes : — 



1. Ligneous framework of the so-called Rope Cactus 

 (Opuntia imbricata Haw.). The specimen is 7 feet 6 inches 

 high, and the greatest diameter of the stem 5 inches. It 

 is stated to be forty years old. It was sent by Mr. H. A. 

 Viney, Public School, Sedgefield, Singleton, and is the 

 largest plant I have seen in New South Wales. 



2. Section of the stem of a grape-vine 3 feet 3 inches in 

 girth. It was cut 3 feet from the ground. u The vine is 

 one of the old-fashioned purple preserving sort." It came 

 from the property of Mr. H. L. White at Belltrees, Scone r 

 and its history can be traced for about seventy years, but 

 it is not known whether it was one of the earliest Busby 

 vines, distributed from the Botanic Gardens from 1833 

 onwards, (see my notes on the history of the vine in New 

 South Wales Agric. Gaz. N.S.W., p. 427, June, 1917). 



3. An old fence-post and its wire, believed by Mr. White 

 to be the remains of the first wire fence erected on the 

 Hunter and probably in New South Wales. It was erected 

 in 1858. It will be observed that the post is pointed and 

 therefore it was driven. It is apparently Ironbark, and 

 sound. The wire is No. 4 galvanised, and wire of this 

 thickness has long since ceased to be used for the purpose. 

 It came from Milgarra, Bunnan, the property of Mr. H. W. 

 Bell. It was presented to the Botanic Gardens by the
