of vegetation and climate seemed to follow the settler with his flocks and herds. After a few years' feeding with stock, water has been found permanently standing in country where it never stood before, and sometimes the tufty herbage has changed into a sward. The flats that used in one season to show a succession of swamps, and in another a surface of bare dusty soil, rifted with yawning cracks, has often become good level turf, intersected with runnels cut by the hoofs of the sheep and cattle."
The first invasion of the new territory across the range led to a terrible feeling of disappointment; true, that on at once crossing the crest of the watershed country was found, which being partly within the influence of the heavier fall of rain, approached in every way the perfection dreamt of by the explorers; but as progress inland was made, a change was found to take place, and, above all, the familiar indigenous grasses were lost, and replaced by what the settlers took to be nothing but worthless weeds. All the now prized edible shrubs, such as the many kinds of saltbush, the cotton-bush, &c., were amongst these despised plants; and even the very stock did not take to them, until some years of use had rendered them familiar. These drought-resisting plants were at first supposed to be confined to the inner slope of the range, but the extended exploration of the continent shows us that where the coast range loses its character of a pronounced range, and is only represented by an insignificant rise, the characteristics of the plain are continued right down to within a short distance of the sea.
This is notably the case on the north, where the Flinders River and its tributaries drain country that bears all the distinctive growth of the interior. On the south coast, west of the Murray, this is also the case, and in these parts, through the depression of the range, the climate is much drier. On the eastern coast, however, the distinction between the uplands and lowlands is strongly marked both in Queensland and New South Wales, even in those cases where the rivers rise in uplands approaching in elevation to the level of the tableland. The eastern coast of northern Queensland is, from its situation and the superior height of the coast range combined, the tropical garden of Australia, the luxuriant growth of vegetation, taking the form of dense scrubs and jungles springing from a deep, rich soil. These scrubs, of slightly varying character, form a characteristic of the whole length of the eastern seaboard, and amongst them we find much valuable timber. The cedar tree is one important feature, and the kauri pine is found in one small tract in the north of Queensland.
Further south, however, the trees grow to an enormous height in the elevated forest lands. Victoria and Western Australia are particularly noted for the giant growth of some of their trees. In Victoria the white gum (EUCALYPTUS AMYGDALINA) has been found growing to a height of over four hundred feet; the red gum (EUCALYPTUS ROSTRATA), and the blue gum (EUCALYPTUS GLOBULUS) also attain a great size in our southern colonies. In Western Australia the jarrah (EUCALYPTUS MARGINATA) and the karri (EUCALYPTUS DIVERSICOLOR) have become noted in the world as being most valuable hardwoods.
Right through the continent, from east to west, the box tree (EUCALYPTUS MALLIODORA) is to be found. On the tableland the timber is altogether of a different growth. The giants of the slopes of the seaward range are replaced by low, stunted, and crooked trees, some of them, however, possessing edible foliage. Most of the acacias are of this kind—the ACACIA PENDULA or myall, the brigalow, the mulga, and yarran. The CAESARIANSAE common all over Australia, under the name of the oak tree.
The difference between the products of the interior upland and the coastal lowland is mainly induced by the difference of climate, those grasses and herbs growing on the tableland, while repellent in appearance and colour, compared to the richer herbage of the coast, possess qualities that render them invaluable as fodder plants. Once let the grasses of the coast lose their moisture from drought, and they become sapless and worthless, but it is not so in the tableland. Months of dry weather have no effect upon the fattening properties of the shrubs; the stock, however, have to become used to feeding on them before their full value is attained.
Amongst the fauna of Australia the distinction between coast and tableland is not so well marked, most of the well-known species ranging indifferently over the whole continent. In the kangaroos, differences in size, colour and appearance can easily be detected in widely separated localities, but they do not amount to anything very noticeable to the ordinary observer. The smaller kinds, the wallaby and kangaroo rat, are common everywhere on the continent. In birds, however, the difference is great, the seeds and fruit on which some birds exist being only found in either the coastal scrubs or lowland country, whilst many of the parrots and pigeons of the interior could not live on the coast. So sharply is the line drawn in some places, that on the dividing watersheds of the east coast flocks of galar parrots and plain-pigeons will be found feeding on the western slope of a ridge, but never by any chance crossing on to the eastern.
Australia is rich in waders, and they are found all over the continent. The beautiful jabiru, or gigantic crane, is equally at home in some lonely waterhole in the far west and at the head of a coast swamp; so, too, the GRUS AUSTRALIS, or native companion, and the quaint and rich-plumaged ibis. The familiar laughing-jackass is to be found everywhere, but his peculiar note differs somewhat in different parts; a blackfellow from the south says that the laugh of the northern bird makes him feel sick, whilst the northern native says the same of the southern kingfisher. The great inland plains are the haunt of the flock-pigeon; in countless myriads, these beautiful birds come at some seasons of the year, and in the morning when flying in to the water they look like distant clouds.
The fish of the tableland differ greatly from those of the coast. In some of the inland lakes and permanent lagoons they are so fat as to be almost uneatable, and at times so plentiful and easily caught that the blackfellows scarcely trouble to get them, which is rarely the case elsewhere. The Australian native is a man with an unknown history whether he is an improvement on his remote ancestors or a degenerate descendant it is impossible to form any idea.
Whoever they were they left nothing behind them, except this wandering savage, and he has neither traditions nor customs that tell us anything of the past. The language is a perfect confusion of tongues, and dialects, words of similar sound and meaning are often found in places hundreds of miles apart; in distinct tribes wherein the rest of the language is altogether different. Their physique does not differ greatly. Perhaps in the north an admixture of Malay blood gives a handsomer cast to the features in individual cases, but the Australian native is unmistakable wherever you meet him, north, south, east or west.
The geological formation of Australia is, as is well-known very old, one third of the continent being desert sandstone with no marine fossils, but although, scantily supplied with water on the surface, there is little doubt of the immensity of the subterranean supply.
Water has been struck by boring five hundred and seventy-two feet, and risen to within ten feet of the surface, and on the Kallara run at one hundred and forty-four, where it rose twenty-six feet above the surface. Water then, will probably be found almost anywhere at a depth of six hundred feet, and a vast portion of the lightly watered plains of the interior will be worked up to their fullest capabilities by means of boring.
It is generally supposed that the first portion of Australia that rose above the sea was the south-east corner where the largest and probably the most active of our volcanoes existed; the rise of the whole continent which subsequently took place would have then left the interior a shallow inland sea, girt round with a broken chain of more or less active volcanoes. In time, these grew extinct, the sea evaporated and we were left with our present coast range, with its now lifeless peaks, and our depressed inland plateau, with its saline flats and lakes.
