TEEE CTJirUEE U SOUTH AUSTRALIA- 89 



EUCALTPTUS SIDEROPHLOIA.— £»»<Aa»>. 

 (The Eed Ironbark.) 



Queensland and New South Wales. The large-leaved " Sydney iron- 

 tark tree," reaching a height of 150ft., -with a diameter of 4ft. (Muel- 

 ler's Eucalyptographia.J 



A most valuable timber tree. The wood is hard, heavy, durable, and 

 largely used for railway and other public works. 



The tree is easily propagated from the seed. The seedlings are hardy, 

 and transplant readily. 



Succeeds well in this colony. Prefers our red chocolate soil to any 

 other. "Wni grow on even somewhat dry sites. 



EUCALTPTTTS GOMPHOCEPHALA.— CamfoZfe. 

 <The Tooart Gum.) 



. Western Australia ; along the coast-line from Moore River to 

 Geographe Bay. — (Mueller). 



A valuable tree, producing a hard, close-grained, and strong timber. 

 Reaches a he^ht of 120ft., with proportionate girth of stem. 



This tree, according to Mueller, grows only in " calcareous sandstone, 

 formed by the wind-drifts of sea-sand." It is, therefore, a valuable tree 

 for growing upon our limestone and brackish soils. I have already tried 

 it with success upon sites of this character. 



ETJCALTPTTJS PILULAHIS.-Sm. 

 (The Blackbult Gum.) 



Indigenous to Victoria, Queensland, and New South Wales. A large 

 tree, reaching 300ft. in height and 45ft. in circumference. — (Mueller's 

 EucalyptographiaJ . 



The tree is of rapid growth, timber of excellent quality, and is in use 

 for general purposes. 



Although the tree is sometimes found in high-lying districts, its chief 

 habitat is on the flats and rich places in the valleys. It, therefore, 

 delights in good loamy "soUs. 



EUCALTPTTTS MAKGIXATA. - Smith. 

 (The Jarrah Gnm.) 



Western Australia. 100ft. to 200ft. in height, growing in vast forests 

 ■somewhat inland from the coast-Hne. 



The most valuable of aU the Eucalypti family as regards timber. 

 The wood is said to be almost indestructible, and is therefore now 

 largely used as railway sleepers, piles for bridges and jetties, and in 

 ship-buUding. Resists the attacks of the white ants and the teredo 

 navalis under the generality of circumstances. The wood, according 

 to Baron von Mueller, is very strong, close-grained, slightly oily, 

 resinous, works well, takes a fine finish, and weighs, when seasoned, 

 about 64lbs. to the cubic foot. 



Gfrows in poor red sandy soil, upon ironstone ridges.
