134 Select Plants for Industrial Culture 



Eucalyptus corynibosa, Smith. 



The principal Blood wood-tree of New South Wales and Queensland. 

 A tree attaining large dimensions; it has a rough furrowed bark and 

 a dark-reddish wood, soft when fresh, but very hard when dry; very 

 durable underground, and therefore extensively used for fence-posts, 

 rails, rail way- sleepers and rough building-purposes. The bark is rich 

 in kino. 



Eucalyptus corynocalyx, F. v. Mueller. 



South- Australia, North- Western Victoria. The Sugar-Gumtree. 

 A timber-tree, attaining a height of 120 feet, length of bole to 60 feet, 

 circumference at 5 feet from the ground reaching 17 feet. The wood 

 has come into use for fence-posts and railway-sleepers. Its durability 

 is attested by the fact, that posts set in the ground fifteen years showed 

 no sign of decay. The tree thrives well even on dry ironstone- 

 ranges. The base of the trunk swells often out in regular tiers. The 

 sweetish foliage attracts cattle and sheep, which browse on the lower 

 branches, as well as on saplings and seedlings. Scarcely any other 

 Eucalypt is similarly eaten (J. E. Brown). In ordinary culture the 

 writer did not find this species of very quick growth; but Mr. Brown 

 records, that under favorable circumstances it will grow one foot a 

 month. 



Eucalyptus crebra, F. v. Mueller. 



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

 land. Wood reddish, hard, heavy, elastic and durable; much used in 

 the construction of bridges and for railway-sleepers, also for wagons, 

 piles, fence-posts. E. leptophleba and E. drepanopliylla are closely 

 allied species of similar value.. They all exude astringent gum- 

 resin, resembling kino in appearance and property, in considerable 

 quantity. 



Eucalyptus diversicolor, F. v. Mueller.* (E. colossea, F. v. M.) 



The Karri of South- Western Australia. A colossal tree, exception- 

 ally reaching the height of 400 feet, with a proportionate girth of the 

 stem. Mr. Muir measured stems nearly 300 feet long without a 

 branch; widths of timber of as much as 12 feet can be obtained. 

 Furnishes good timber for building, even for masts, likewise for planks; 

 also valuable for shafts, spokes, felloes, fence-rails; it is elastic, but 

 not so easily wrought as that of E. marginata. Mr. Gr. Simson does 

 not deem the wood very durable, if exposed to moisture or if in con- 

 tact with the ground. Its strength in transverse strain is equal to 

 English oak. Wood exposed to the wash of the tide for twenty-six 

 years continued quite sound. Fair progress of growth is shown by the 

 trees planted even in dry exposed localities in Melbourne. The shady 

 foliage and quick growth of the tree promise to render it one of our 

 best for avenues. In its native localities it occupies fertile, rather 

 humid valleys, and resembles there in habit the E. amygdalina var. 

 regnans of South-Eastern Australia.
