«8 TEEE CULTURE IN SOUTH AUSTRALIA. 



From its filose compact shape, and the fact of its being little injured by 

 smoke, the tree is a good one for planting in towns and cities. Makes 

 an imposing avenue tree. It can be grown very closely together ; and 

 from this fact I have recommended it as a good shelter-hedge. (See 

 Figsi 60, 61, 62, and 63.) 



Grows well in this colony, where fine large specimens may now be 

 seen of it in different parts. 



Propagate by cuttings put out in nursery lines July or August.
