THE STRINGY-BARIC TREE (Eucalyptus gigantea , E. robusta, or E. obliqua)

Is of straight growth, and takes its name from the strip-like character of its bark. It is very abundant in Australia 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.
