employed in those forest-districts, where it is abundant, and has 

 proved a valuable timber It is especially esteemed for wheel- 

 wrights' work [Falck], Excellent for fuel. Our local ex- 

 periments showed the strength greater than that of E. amygdalina 

 and E. obliqua, but less than that of E. globulus. Meltitose is 

 formed occasionally on this tree and also on the following species. 

 In this species and others the author counted more than one 

 annual wood-ring without clearly visible demarcation of yearly 

 increment. 



Eucalyptus Ounnii, J. Hooker.* 



Known as Swamp -Gum tree, the mountain variety as Cider- tree. 

 Victoria, Tasmania and New South Wales, ascending alpine eleva- 

 tions. In the low-land along fertile valleys it attains a considerable 

 size, and supplies a strong useful timber. It is this species, which 

 survived severe frosts at Kew-Gardens. Bees obtain unusually 

 much honey from the flowers of this species. Cattle and sheep 

 browse on the foliage. Timber found to be almost equal in 

 strength to that of E. macrorrhyncha, E. rostrata and E. globulus. 

 The other very hardy Eucalypts comprise E. pauciflora, E. alpina, 

 E. urnigera, E. coccifera and E. vernicosa, which all reach heights, 

 covered with snow for several months in the year. Succeeded 

 well at Arran fCapt. Brown and Rev. D. Landsborough] . The 

 percentage of kino-tannin in the absolutely dry bark is from 9| to 

 11^ [J. H. Maiden]. Any cutting down of healthy Eucalypts in 

 places of centres of populations, to substitute there for a zone of 

 evergreen vegetation the northern deciduous trees extensively, is 

 regretable, as therewith the far superior hygienic value of the 

 Eucalypts is lost, and the aspect of the Australian landscape 

 during half a year rendered dismal, so far as vegetative features 

 are concerned. 



Eucalyptus haemastoma. Smith. 



One of the White Grumtrees of New South Wales and Southern 

 Queensland, abundant in many localities. This species attains a 

 very considerable size, but furnishes fencing and rough building 

 material only and fuel of inferior quality [Rev. Dr. Woolls], yet it 

 claims our attention particularly as fit for culture on sandy land, 

 for which purpose very few other Eucalypts are suited, thus afford- 

 ing shelter and aiding* salubrity. A variety occurs with persistent 

 stringy bark. Dr. Bancroft finds the yield of kino from the stem 

 and that of oil from the foliage considerable. Mr. Maiden deter- 

 mined the tannin in this kino to be about 54 per cent, ; the kino is 

 soluble as well in water as in alcohol. 



Eucalyptus hemiphloia, F. v. Mueller.* 



South-Eastern Australia, particularly inland. A tree, reaching 

 90 feet in height and 4 feet in stem-diameter. Trunk generally 

 not tall. Regarded as a timber-tree of great excellence. It is
