TiMBEKs OF Victoria. 
Many of the timber trees of Victoria are indigenous to 
the adjoining colony of New South Wales and have been 
already described, and also to Tasmania, although they are 
sometimes marked by different botanical names. 
Such are the Eed Gums found in the neighbourhood of 
the Murray River, which divides Victoria from New South 
Wales. 
The Red Ironbark (E. leucoxylon), which is called blue 
gum in South Australia, as it is somewhat like a gum in 
appearance, is a much more substantial timber than the 
red ironbark of New South Wales, and is really a hard, 
dense, durable timber, much used for bridge beams and 
piles, and ranks with grey box as a material for sleepers. 
Blue Gum, which has the same botanical name as the 
blue gum of Tasmania, but is not nearly such a large or 
valuable tree, although the timber is strong and durable, is 
used for railway sleepers and upper timbers in jetties. 
The Spotted Gum (E. goniocalyx) is very similar in 
appearance to blue gum, for which it is often sold, and is 
used for the same purposes.
