170 TWO WELL-KNOWN SPECIES OF EUCALYPTUS, 



and I have, therefore, decided to include this southern variety of 

 " Yellow Gum " in this species. 



One is very reluctant to dissent from the Baron's classification, 

 but his placing the " Yellow Gum " (Woolls) under E. pnncLata, 

 DC. {he. cit.), appears to me sufficient evidence that he was not 

 quite acquainted with the characteristic differences and habits of 

 the living trees. 



Although often found growing intermixed with E. viminalis, 

 yet the two species are never confused, as each has its own dis- 

 tinctive facies; and they differ in the fruits, timber, and oil. 



Timber. — The timber is much more difficult to season than that 

 of E. Guntdi, Hook., and is also specifically heavier. It is a close- 

 grained, hard timber of a light reddish colour, and I should con- 

 sider it a much more durable timber than E. Gunnii or E. 

 viminalis. Sir W. Macarthur states that it is "said to be good." 

 Dr. Woolls was of opinion that it is not suitable for any purpose, 

 but Mr. H. Rumsey, of Barber's Creek, informs me that sound 

 logs will last 30 years in the ground. My own opinion is that if 

 well seasoned it is a good, sound, hard, durable timber, and useful 

 for many purposes. 



Oil. — The leaves are not rich in essential oil, as 394 lbs. of 

 leaves with terminal branchlets, distilled June, 1898, gave 15oz., 

 or "243 %. It is slightly red in colour, and is probably (from 

 preliminary tests) not a good oil, and as the yield is not good it 

 could not profitably be extracted.
