Eucalyptus tereticornis, Smith.* 



From Eastern Queensland, where it is termed Red Gumtree, to 

 Gippsland, attaining a height of 160 feet. Closely allied to E. 

 rostrata. Will thrive on undrained ground. The timber is esteemed 

 for the naves and felloes of wheels. For telegraph-poles and railway- 

 sleepers it is inferior to some of the Ironbark-trees, lasting a shorter 

 time. Mr. A. R. Crawford observes, that he has never known posts 

 of this wood decaying from dry rot, nor saw it as round posts ever 

 attacked by the termites. Quite underground it remains sound much 

 longer [Thozet] ; but much depends, as regards its durability, on the 

 locality where it is obtained, and the manner of drying, a remark 

 which applies also to many other Eucalypts. The curly butts fur- 

 nish material for handsome heavy furniture [Crawford]. Shavings 

 of the most antiseptic kinds of Eucalyptus-woods should prove a good 

 packing material for fresh fruits on trans-oceanic voyages. The tree 

 has thriven well in Oudh and the North- West Province of India [J. 

 S. Gamble]. In Hoshiarpur this species attained a height of 115 feet 

 in sixteen years [W. Coldstream]. Has prospered remarkably in the 

 Punjab, attaining to a height of 60 feet in seven years [Major P. C. 

 Napier]. The oil of the foliage contains no Cineol [Schimmel]. 



Eucalyptus terminalis, F. v. Mueller.* 



The Bloodwood-tree of the northern and central parts of Australia, 

 closely allied to E. corymbosa, attaining a considerable size, thriving 

 even in sandy desert-country. The wood is dark-red, hard and ex- 

 tremely tough, particularly fit for boards, as it does not crack. Locally 

 used for piles, for foundation-blocks of buildings, as one of the best 

 woods there [Th. Gulliver]. The tree resists the enormous desert- 

 heat of Central Australia, where the shade temperature ranges from 

 27 to 122 F., and where the annual rainfall in some years is only 2 

 inches, and seldom more than 10 inches. Particularly adapted for 

 dry tropical climes. 



Eucalyptus tessellaris, F. v. Mueller.* 



Central and Northern Australia and Queensland. The Moreton- 

 bay-Ash. This tree reaches even on dry ridges a height of 150 feet, 

 surpassing any other Central- Australian species in loftiness, and there 

 resists the severe summer-heat [Rev. H. Kempe] . Furnishes a brown, 

 rather elastic wood, not very hard, easily worked, of great strength 

 and durability, available for many kinds of artisans' work, and par- 

 ticularly sought for staves and flooring. The tree exudes much 

 astringent kino [P. O'Shanesy]. The oil does not contain Cineol 

 [Schimmel]. Several other species might yet be mentioned, particu- 

 larly from tropical Australia, but we are not yet well enough 

 acquainted with their technical value. All Eucalypts are eligible 

 for the production of tar, pitch, acetic acid, wood-spirit, paper-material, 

 potash and various dye-substances on a commercial scale.
