Naturalisation in Extra-Tropical Countries. 199 



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, durable even underground, 

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

 breast-hooks in ship-building ; used with advantage and preferentially 

 for wood-bricks in the city of Sydney ; the young trees serve for 

 telegraph-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. Bancroft]. 

 This species did particularly well at George-town in British Guiana, 

 growing at a rate from 10 to 18 feet yearly while in a young state 

 [Jenman]. It proved also valuable for the mountains of Ceylon, 

 where it grew 64 inches in girth in eight years, and where it exceeded 

 any other Eucalypt in celerity of growth [Alexander]. Not fit 

 for dry regions. * Mr. J. H. Maiden furnished an extensive original 

 article on this species for the Agric. Gazette of New South Wales, 

 May, 1894. From well matured seeds simply scattered during the 

 cool season on suitable soil of openings in forests Eucalypts of almost 

 any kind can be established or regenerated with the utmost facility. 



Eucalyptus microtheca, F. v. Mueller. 



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

 tropical inland regions of Australia. The "Coolibah" of the 

 aborigines according to the Rev. Dr. Woolls. The tree wants ferru- 

 ginous-gravelly soil, perfectly drained. Withstands unscorched a 

 frequent heat of 1 56 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. 

 Naudtn]. 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]. 



Eucalyptus miniata, Cunningham. 



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

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

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

 reddish colour.
