Whoever has seen any recent map of New Holland must have been struck with the curious appearance of a vast semicircle of water, called Lake Torrens, near the southern coast, and extending many miles inland from the head of Spencer's Gulph. A range of hills, named Flinders' Range, runs to a considerable distance inland, taking its rise near the head of the gulph just mentioned, and Lake Torrens nearly surrounds the whole of the low country extending from this mountainous ridge. This immense lake is supposed to resemble in shape a horse-shoe, and to extend for full 400 miles, whilst its apparent breadth is from 20 to 30. The greater part of the vast area contained in its bed is certainly dry on the surface, and consists of a mixture of sand and mud, of so soft and yielding a character as to render perfectly unavailing all attempts either to cross it, or to reach the edge of the water, which appears to exist at a distance of some miles from the outer margin. Once only was Mr. Eyre, the enterprising discoverer of this singular lake, able to taste of its waters, and then he found them as salt as the sea. The low, miserable, desert country in the neighbourhood, and Lake Torrens itself, act as a kind of barrier against the progress of inland discovery at the back of the colony of South Australia, since it is impossible to penetrate very far into the interior, without making a great circle either to the east or to the west. The portion of the bed of the lake which is exposed is thickly coated with particles of salt; there are few trees or shrubs of any kind to be found near, nor are grass and fresh water by any means abundant. Altogether, the neighbourhood of Lake Torrens would seem a very miserable region, and forms a strong contrast to the smiling and cultivated district of which it forms the back country.[28] [28] These particulars are taken from the South-Australian Almanac for 1841, pp. 68-73.
