Character of the Australian continent — of its rivers — peculiarity¹ of the Darling — sudden floods to which it is subject — character of the Murray — its periodical rise — bounty² of providence³ — geological position of the two rivers — observations — results — Sir Thomas Mitchell’s journey to the darling — its junction⁴ with the Murray — anecdote⁵ of Mr. Shannon — Captain Grey’s expedition — Captain Sturt’s journey — Mr. Eyre’s second expedition — voyage of the Beagle — Mr. Oxley’s opinions — state of the interior in 1828 — character of its plains and rivers — junction of the Darling — fossil bed of the Murray — former state of the continent — theory of the interior.

 

The Australian continent is not distinguished⁶, as are many other continents of equal and even of less extent, by any prominent geographical⁷ feature. Its mountains seldom exceed four thousand feet in elevation⁸, nor do any of its rivers, whether falling internally or externally, not even the Murray, bear any proportion to the size of the continent itself. There is no reason, however, why rivers of greater magnitude, than any which have hitherto been discovered in it, should not emanate⁹ from mountains of such limited altitude, as the known mountains of that immense and sea-girt territory. But, it appears to me, it is not in the height and character of its hilly regions, that we are to look for the causes why so few living streams issue from them. The true cause, I apprehend¹⁰, lies in its climate, in its seldom experiencing other than partial rains, and in its being subject to severe and long continued droughts. Its streams descend¹¹ rapidly into a country of uniform equality of surface, and into a region of intense heat, and are subject, even at a great distance from their sources, to sudden and terrific floods, which subside¹², as the cause which gave rise to them ceases to operate; the consequence is, that their springs become gradually weaker and weaker, all back impulse is lost, and whilst the rivers still continue to support a feeble current in the hills, they cease to flow in their lower branches, assume the character of a chain of ponds, in a few short weeks their deepest pools are exhausted¹³ by the joint¹⁴ effects of evaporation¹⁵ and absorption, and the traveller may run down their beds for miles, without finding a drop of water with which to slake¹⁶ his thirst.

 

In illustration of the above, I would observe that during the progress of the recent expedition up the banks of the Darling, and at a distance of more than 300 miles from its sources, that river rose from a state of complete exhaustion¹⁷, until in four days it overflowed¹⁸ its banks. It was converted in a single night, from an almost dry channel, into a foaming¹⁹ and impetuous stream, rolling along its irresistible²⁰ and turbid²¹ waters, to add to those of the Murray.

 

There can be no doubt, but, that this sudden rise in the river, was caused by heavy rains on the mountains, in which its tributaries²² are to be found, for the Darling does not receive any accession to its waters below their respective junctions²³, of sufficient magnitude to account for such an occurrence. 1

 

1. The principal tributaries of the Darling, are the Kindur, the Keraula, the Namoy, and the Gwydir. They are beautiful mountain streams, and rise in the hilly country, behind Moreton Bay, in lat. 27 degrees, and in longitude²⁴ 152 degrees E.

 

When, on the return of the expedition homewards the following year, some two months later in the season than that of which I have just been speaking, Oct. 1844, there had been no recurrence²⁵ of the flood of the previous year, but the Darling was at a still lower ebb²⁶ than before, and every lagoon²⁷, and creek²⁸ in its vicinity had long been exhausted and waterless. 2 Now, it is evident, as far as I can judge, that if the rains of Australia were as regular as in other countries, its rivers would also be more regular in their flow, and would not present the anomaly they now do, of being in a state of rapid motion at one time, and motionless at another.
