CHAPTER IV
IN THE BUSH
One great source of wealth to Western Australia are the karri forests, covering thousands of square miles. Karri is a kind of eucalyptus closely allied to the better-known jarrah, one of the hardest woods in existence. It has been used at home to pave the streets of London. In all but one respect karri is as good as jarrah, its only point of inferiority is that it cannot be employed for underground purposes, while jarrah can be left under water for twenty years without being any the worse for it. Karri has to be specially prepared—"powellised" is the technical term—and that is an expensive process. Otherwise it is almost impossible to tell the two woods apart, except by the ash after burning.
Western Australia asserts that its karri trees are the tallest in the world, though Victorians make the same claim for the giant gums of Gippsland. So far these Gippsland trees have been proved to be the tallest in Australia.
