than Europe or America or Asia--and its story is a little blurred and uncertain partly for that reason.
Look at the map and see its shape--something like that of a pancake with a big bite out of the north-eastern corner. In the very old days Australia was joined to those islands on the north--the East Indies--and through them to Asia; but it was countless ages ago, for the animals and the plants of Australia have not the least resemblance to those of Asia. They represent a class quite distinct in themselves. That proves that for a very long time there has been no land connection between Australia and Asia; if there had been, the types of flower and of beasts would be more nearly kindred. There would be tigers and elephants in Australia and emus in Asia, and the kangaroo and other marsupials would probably have disappeared. The marsupial, it may be explained, is one of the mammalian order, which carries its young about in a pouch for a long time after they are born. With such parental devotion, the marsupials would have little chance of surviving in any country where there were carnivorous animals to hunt them down; but Australia, with the exception of a very few dingoes, had no such animals, so the marsupials survived there whilst vanishing from all other parts of the earth.
When Australia was sundered from Asia, probably by some great volcanic outburst (the East Indies are to this day much subject to terrible earthquakes and volcanic outbreaks, and not so many years ago a whole island was destroyed in the Straits of Sunda), the new continent probably was in the shape somewhat of a ring, with very high mountains facing the sea, and, where now is the great central plain, a lake or inland sea. As time wore on, the great mountains were ground down by the action of the snow and the rain and the wind. The soil which was thus made was in part carried towards the centre of the ring, and in time the sea or lake vanished, and Australia took its present form of a great flat plain, through which flow sluggish
