AUSTRALIA: ITS PLAINS AND TABLELANDS. Definitions.?A Plain is land lying at a lower level than 500' feet. It may be an expanse of verdure and fertility, as in the case of short river valleys; but it is more usual to find great plains presenting every variety of surface from cold, bleak swamps to rough, sandy flats. A Tableland or Plateau is land at a higher elevation than 500 feet, of a fairly level surface, of considerable length and breadth, bearing perhaps upon it more than one mountain chain, and forming the gathering grounds of many streams. The Central Plain, or plain of the Murray river, begins near Portland, at the mouth of the Glenelg, and is bounded by an almost straight line to the Wimmera river; thence by a line joining the Wimmera to Albury; and at Albury by the 147th meridian to 27 S. lat. Following this latitudinal line to the west, it is intersected by the Cheviot, Grey, and Stanley ranges, which divide its northern portion into two distinct parts. To the east of these ranges it follows the course of the Thompson?an affluent of the Barcoo? almost to its source as a narrow river valley, and is bounded by 28 S. lat. in South Australia; it extends westward so as to include Lake Eyre. This plain is here bounded by the high lands between Lakes Eyre?70 feet high?and Blanche, and by the Lofty range. This great area is 500, 000 square miles in extent. In the descriptions of the rivers in a later chapter some details of the lands embraced within this area will be given. All that need be here said is that, in general terms, this plain is eminently suitable for pasture, has an inadequate supply of water, is scanty in forest growth, and has an average summer temperature of 89 '3 Fahrenheit.
