as it grows there at a much lower level than in the latitude of 

 Sydney. 



At about 10 miles south-westerly from Orange there is a high 

 mountain of volcanic origin, exceeding 4,000 feet above sea level 

 and known as the Canoblas. It is of intense geological interest, for 

 in addition to the petrological study it affords of the various forms 

 of volcanic rock of which it is composed, and the probable remains 

 of an ancient crater on the top, just south of the Trig, station, 

 the original lava flow has covered and thereby protected older 

 sedimentary rocks of the Devonian and Silurian periods, and 

 these ma}^ be seen in places protruding from under the base of 

 the mountain. To the eastward, near Forest Reefs, Tertiary 

 fossil fruits may be found buried under a great thickness of basalt 

 which was possibly emitted from or contemporaneous with the 

 outflow^s from the Canoblas. Some rocks containing graptolites 

 of probably Lower Silurian origin may be found towards Diggers' 

 Creek near Cadia. 



The road from Orange to Cargo passes the base of the mountain 

 on the western side at about 7 miles from Orange, and the 

 Eucalypts noticed between Orange and this point are E. dives, 

 E. viminalis, E. Br-idgesiana, E. r)iacrorhyncha and E. coriaceaj 



On ascending the mountain from about the 7-miIe post the 

 following plants are noticed : — Eucalyptus macrorhyncha, E. 

 melliodoi'a, E. Bridyesiana, E. viminalis, E. Cambagei, E. dives, 

 Acacia dealbata, A. melanoxylon, ^.^v., Exocarpus ciqjressiformis, 

 Thysanotus fube?-osus, R.Br. (Fringed Violet), Veronica perfolio- 

 lata, R.Br., Calythrix tetragona, Stella7'ia 2Junge7is, Brong., Ery- 

 fh?rea australis, R.Br., Helichrysur)i apicidatum, DC, and Lepto- 

 spermum lanigevam (?), Sm. 



Erythr(pa australis is a small plant which has been seen extend- 

 ing over most of the area described in these papers, and is to be 

 found in the coastal area as well. It was used by the aborigines 

 for medicinal purposes, and is not confined to this State. 



Acacia melanoxylon is the same as the famous Tasmanian 

 Blackwood, but in New South Wales it does not grow into such 

 fine trees as may be found in Victoria and Tasmania. It is often
