 Australia," p. 461). 



JARRAH,* OR AUSTRALIAN MAHOGANY 



{Eucalyptus marginatd), 



is also found in South- Western Australia, where it is 

 said to be very abundant. It is of straight growth and 

 very large dimensions, but, unfortunately, is liable to 

 early decay in the centre. The sound trees, however, 

 yield solid and useful timber of from 20 to 40 feet in 

 length by 1 1 to 24 inches square, while those with faulty 

 centres furnish only indifferent squares of smaller sizes, 

 or pieces unequally sided, called flitches. 



* This tree, Jarrah, must not be confounded with the -Varrah {Eucalyptus 

 rostrata).
