Of the sylvicultural requirements of the various species 

 of Eucalypts we know little. No professionally trained 

 Forester has visited and described the Eucalypts in their 

 native forests, and our Eucalypt plantations in 8. Africa 

 are as yet too young and partial to throw much light on a 

 subject so important to Forestry in this country. Broadly 

 speaking the Eucalypts are light-demanders and grow in 

 open mixed forests. But certain species such as Karrie 

 form dense pure forests. 



THE BEST TIMBER EUCALYPTS. 



Broadly speaking, it may be said that the West Australian 

 Jarrah and East Australian Iron-barks, and the inland 

 Rostrata Gum, occupy the first place. But close on these 

 follow the West Australian Karrie, the South Australian 

 Sugar-gum and the valuable hard woods of Eastern 

 Australia enumerated below. Many of these extend into 

 the scant winter rainfall of South Australia. We get
