foliage is available for profitable oil distillation. The shining 

 white or purplish bark does not give off a white coloration like E. 

 redunca. 



Eucalyptus saligna, Smith. 



The Blue or Flooded Gum-tree of New South Wales. A tall 

 straight-stemmed species attaining a diameter of 7 feet. According 

 to the Rev. Dr. Woolls the wood is of excellent quality, and largely- 

 used for shipbuilding. The tree is generally found on rich soil 

 along river-banks. 



Eucalyptus salubris, F. v. Mueller. 



The Gimletwood or Fluted Gum-tree of West and Central Aus- 

 tralia, living on poor dry soil. It is generally a slender-stemmed 

 tree, 100 feet high, 2 feet in diameter, with a small crown. The 

 bark is shining with a brownish tinge, and broad, longitudinal, and 

 often twisted impressions, or roundish, blunt, longitudinal ridges. 

 The wood is hard and tough, but comparatively easily worked, 

 heavier than water, even when dry. It serves for roofing, fencing, 

 poles, and shafts, etc. For xylography it is better than Pear- 

 tree wood, and deserves attention for this purpose. The tree 

 exudes kino. 



Eucalyptus siderophloia, Bentham.* 



The Large-leaved or White Ironbark-tree of New South Wales 

 and South Queensland, attaining a height of 150 feet. According 

 to the Rev. Dr. Woolls this furnishes one of the strongest and 

 most durable timbers of New South Wales ; with great advantage 

 used for railway-sleepers and for many building purposes. It is 

 highly appreciated by wheelwrights, especially for spokes, also well 

 adapted for tool-handles. Found by us to be even stronger than 

 Hickory, and only rivalled by E. Leucoxy Ion and, though less, by E. 

 polyanthema. It is harder than the wood of E. Leucoxylon, 

 but thus also worked with more difficulty. The price of the 

 timber is about 2s. 6d. per cubic foot in the log. The tree yields 

 much kino. 



Eucalyptus Sieberiana, F. v. Mueller. (E. virgata, Bentham, not 



Sieber,) 



South-East Australia. A straight-stemmed tree up to 150 feet in 

 height and 5 feet in stem diameter, vernacularly known as Moun- 

 tain Ash in Gippsland and New South Wales, as Ironbark-tree or 

 Gumtop in Tasmania. The wood is of excellent quality, strong 

 and elastic, thus used for implement handles, cart-shafts, swingle- 

 trees, also for fencing and for general building purposes. It burns 

 well, even when freshly cut. Systematically the species is very 

 closely allied to E. haemastoma, but much superior as a timber-tree
