Jarrah in South- Western Australia, at nine million acres, and the 

 yield at an average about 500 cubic feet of good timber per acre. 

 The trees should be felled in autumn or towards the end of summer, 

 in which case the timber will not warp. The tree grows chiefly on 

 ironstone-ranges. It does not accommodate itself to such a variety 

 of climes and soils as many other Eucalypts. At Melbourne it is 

 not quick of growth, if compared to E. globulus or to E. obliqua, 

 but it is likely to grow with celerity in mountain-regions. It suc- 

 ceeds well on the mountains of Ceylon [Alexander]. Massed in its 

 native country it presents the features of the East Australian 

 stringy bark-forests. Stems of this tree have been measured 80 feet 

 to the first branch, and 32 feet in circumference at 5 feet from the 

 ground. Instances are even on record of the stem having attained a 

 girth of 60 feet at 6 feet from the ground, through the formation of 

 buttresses. To prevent rending of the sawn- timber, Mr. Simpson 

 recommends it to be covered up with saw-dust. 



Eucalyptus melanophloia, F. v. Mueller. 



The Silver-leaved Ironbark-tree of New South Wales and Queens- 

 land. A middle-sized tree with a deeply furrowed bark and mealy 

 whitish foliage. The timber is strong and durable, and used for 

 telegraph-poles and railway-sleepers ; it is however apt to rend, 

 when exposed to the sun, unless well seasoned. The timber of all 

 ironbark-trees is applicable for wood-bricks used in street-paving. 

 Mr. Cosmo Newbery obtained from the bark 9 to 10 per cent, tannin. 



Eucalyptus melliodora, A. Cunningham.* 



The Yellow Boxtree of Victoria and some parts of New South 

 Wales and Southern Queensland, of a spreading habit of growth, 

 attaining a height of about 120 feet, with a comparatively stout stem. 

 The wood resembles that of E. rostrata in texture, but is of a paler 

 colour, and not quite so durable ; it is fully as strong, though second 

 to that of E. Leucoxylon, E. siderophloia", E. polyanthema, and the 

 best E. globulus ; it is esteemed for wheelwrights' and other artisans' 

 work, in shipbuilding, and supplies excellent fuel. Weight of a 

 cubic foot of absolutely dried wood between 67 and 70 Ibs., equal to 

 specific gravity 1-081-M25 [F. v. M. and Hummel]. The young 

 trees are used for telegraph-poles. Flowers much sought by bees, 

 as they are particularly meliigerous. 



Eucalyptus microcorys, F. v. Mueller.* 



One of the Stringybark-trees of New South Wales and South 

 Queensland, mostly known as Tallowwood-tree by the colonists. It 

 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. amygdalina and E. diversi- 

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