very beautiful. It is not too hard, and hence is more easily worked 

 than E. redunca and E. loxophleba. The wood from the hills is 

 darker, tougher and heavier than that from the plains. Well 

 seasoned timber weighs about 64 Ibs. 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 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- 

 \J^anges^ 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 succeeds well on the mountains of Ceylon 

 [Alexander] . 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. 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. Mr. Cosmo N"ew- 

 bery 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. Leu- 

 coxylon, E. siderophloia, E. polyanthema and the best E. globulus ; 

 it is esteemed for wheelwrights' and other artisans' work, in ship- 

 building, and supplies excellent fuel. Weight of a cubic foot of 

 absolutely dried wood between 67 and 70 Ibs., equal to specific 

 gravity 1 081-1*125 [F. v. M. arid Hummel '. The young trees are 

 used for telegraph-poles. Flowers much sought by bees, as they 

 are particularly melligerous. 



Eucalyptus microcorys, F. v. Mueller.* 



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

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