Jarrah (Eucalyptus marginata), one of the most valuable timber-trees of Australia. The trees reach a great size, yielding squared logs forty feet long and twenty-four inches across. The wood is hard, heavy, mahogany-red in colour, sometimes beautifully figured, and containing a resin which enables it to stand exposure and to resist the action of sea-water, of ship-worms, or of white ants; but it is somewhat brittle.
