THE STRINGY-BARIC TREE ( Eucalyptus gigantea , E. 
robust a, or E. obliqua) 
Is of straight growth, and takes its name from the strip¬ 
like character of its bark. It is very abundant in Aus¬ 
tralia and Van Diemen’s Land,, and flourishes well in 
any situation, provided the soil be dry. It attains a 
height of from 100 to 230 feet, with a diameter of from 
3 to 15 feet. 
The wood is of a brown colour, hard, heavy, strong, 
close, and straight in the grain. It works up well, and 
is employed in the colonies in ship-building, for planking, 
beams, keels, and keelsons, and in civil architecture for 
joists, flooring, &c. Upon the farms it is used for fences 
■and agricultural implements ; it is also employed for 
furniture and for all ordinary purposes.
