140 Select Plants for Industrial Culture 



per cubic foot; freshly cut, from 71 to 76 Ibs. It is one of the 

 least inflammable woods according to Captain Fawcett, and is locally 

 regarded as one of the best woods for charcoal. Mr. H. E. Victor, 

 C.E., of Perth, estimates the area covered at present by marketable 

 Jarrah in South-Western Australia at nine million acres, and its 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. 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. Massed in its native country it presents the 

 features of the East-Australian stringybark-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. 



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 barlv and mealy 

 white foliage. The timber is strong and durable, and used for tele- 

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

 exposed to the sun, unless well seasoned. 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; 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 color, and not .quite so 

 durable; it is fully as strong, though second to that of E. Leucoxylon, 

 E. siderophloia and E. polyauthema in this respect, but equalling that 

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

 work, in ship-building, and supplies excellent fuel; the young trees are 

 used for telegraph-poles. Flowers much sought by bees. 



Eucalyptus microcorys, F. v. Mueller.* 



One of the Stringy bark-trees of New South Wales and South - 

 Queensland, mostly known as Tallow-wood by the colonists. It 

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

 diameter. The wood is yellowish, free from kino-veins, easily 

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

 as to be quite slippery when fresh cut (Ch. Fawcett). This oily sub- 

 stance, 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 also hard and durable underground, and is 

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

 breasthooks in ship-building; the young trees serve for telegraph-, 

 poles. The foliage is remarkably rich in volatile oil. This species
