shafts and frames of carts and otlier work requiring hardness, 

 toughness and elasticity. 



Eucalyptus crebra, F. v. Mueller. 



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

 Queensland. Wood reddish, hard, heavy, elastic and 

 durable, much used in the construction of bridges, also for 

 waggons, piles, fencing, &c. E. melanophloia, F. v. M., 

 the Silver-leaved Ironbark-tree, and E. leptophleba, E. 

 trachyphloia and E. drepanophylla are closely allied species of 

 similar value. They all exude astringent gum-resin in 

 considerable quantity, resembling kino in appearance and 

 property. 



Eucalyptus diversicolor, F. v. Mueller. 



The Karri of South-west Australia. A colossal tree, excep- 

 tionally reaching the height of 400 feet, with a proportionate 

 girth of the stem. Furnishes good timber for ship and boat 

 planks, particularly for masts, likewise for wheels. Fair 

 progress of growth is shown by the young trees, planted even 

 in dry exposed localities in Melbourne. The shady foliage and 

 dense growth of the tree promise to render it one of our best 

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

 humid valleys. 



Eucalyptus Doratoxylon, F. v. Mueller. 



The Spear-wood of South- West Australia, where it occurs in 

 sterile districts. The stem is slender and remarkably 

 straight, and the wood of such firmness and elasticity, that

 blue-gum-tree wood, available for many purposes, and largely 

 utilised for shipbuilding. 



Eucalyptus globulus, La Billardiere. 



Blue-Gum-tree of Victoria and Tasmania. This tree is of 

 extremely rapid growth, and attains a height of 400 feet^ fur- 

 nishing a first-class wood ; shii)builders get keels of this tim- 

 ber 120 feet long; besides this they use it extensively for 

 planking and many other parts of the ship, and it is considered 

 to be generally superior to American Rock Elm. A test of 

 strength has been made between some Blue Gum, English 

 Oak, and Indian Teak. The Blue Gum carried 14 lbs. weight 

 more than the Oak and 17 lbs. 4 ozs. more than Teak upon 

 the square inch. Blue-Gum wood, besides for shipbuilding, 

 is very extensively used by carpenters for all kinds of out-
