There are one or two interesting facts from Australia, although not about gold: the bodies of Dr Leichardt and some of his exploring party, are said to have been discovered near Moreton Bay, where they had been murdered by the natives; and Sir Thomas Mitchell, the well-known surveyor-general, has invented a steam-propeller on the principle of the _boomerang_, which, when applied to a boat, answered expectation.
