attains a great size ; barrel up to 100 feet in length and to 7 feet 

 in diameter. The whole height is sometimes nearly 300 feet [Faw- 

 cett]. According to Mr. Clement Hodgkinson it is probably the 

 third in height among the Eucalypts, E. amygdaliiia and E. diversi- 

 color being first and second, but perhaps E. obliqua, E. Raveretiana, 

 E. pilularis, E. goniocalyx and particularly E. globulus get as 

 high, the latter reaching occasionally 330 feet as recorded by Mr. 

 Backhouse. The wood is yellowish, free from kino-particles, easily 

 worked by saw or plane ; it is of a very greasy nature, so much so 

 as to be quite slippery when first cut [Ch. Fawcett]. This oily 

 substance, very similar to viscin, of which it contains about 1 per 

 cent., prevents the wood from splitting and twisting, though not 

 from shrinking. The timber is hard and durable also underground, 

 and is employed for railway-sleepers, wheelwrights' work, for knees 

 and breast-hooks in ship-building ; the young trees serve for tele- 

 graph-poles. The foliage is remarkably rich in volatile oil. The 

 kino differs from that of other Stringybark-trees in being soluble 

 only in warm water and in hot alcohol ; it contains catechu [J. 

 H. Maiden]. Dr. Dymock records the astonishing fact, that in 

 some parts of India this tree grew 30 feet in two years [Dr. Ban- 

 croft!. This species did particularly well at George-town in British 

 Guiana, growing at a rate from 10 to 18 feet in a year while in a 

 young state [Jenman]. It proved also valuable for the mountains 

 of Ceylon, where it grew 64 inches in girth in 8 years [Alexander]. 



Eucalyptus microtheca, F. v. Mueller. 



Widely dispersed over the most arid extra-tropical as well as 

 tropical inland-regions of Australia. Withstands unscorched a 

 frequent heat of 156 F. in Central Australia, yet neither affected 

 by exceptionally severe frosts (18 F.) in the -South of France, when 

 many other Eucalypts suffered. The development of this species 

 in Southern France and Algeria has been marvellously quick [Prof. 

 ISTaudin]. One of the best trees for desert-tracts; in favorable 

 places 150 feet high. Wood brown, sometimes very dark, hard, 

 heavy and elastic ; it is prettily marked, hence used for cabinet- 

 work, but more particularly for piles, bridges and railway-sleepers 

 [Rev. Dr. Woolls]. 



Cucalyptus miniata, Cunningham. 



Litoral North- Western Australia. Attains a height of 80 feet. 

 Likes somewhat ferruginous soil [M. Holtze]. The brilliancy of 

 its orange-colored flowers can hardly be surpassed. Yields kino of a 

 reddish color. 

 Eucalyptus Muelleriana, Howitt. 



Gippsland, on sandy clay. Yellow Stringybark tree. Maxi- 

 mum height 170 feet, with a straight rather massive bole. The 

 wood is dark, fissile, free from kino-veins or shakes, clear in the 

 grain and very durable, used for splitting and sawing. Fence- 

 . posts of this timber have lasted for more than 30 years [A. W, 

 Howitt].
