Satisfied, after consultation with his companion Hume, that there was no obstacle to their onward march, they left their position, intending, as Sturt says, "to close with the marshes."
The night of the first day found them camped amongst the reeds, which they came upon sooner than they expected, and the next day they halted for the purpose of preparing the dispatches for the Governor. On the morning of the 26th, the journey was resumed, the two messengers leaving for Bathurst, the rest proceeding onward until checked by finding themselves in the great body of the marsh, which spread in boundless extent around them.
"It was evidently," says the leader, "lower than the ground on which we stood; we had, therefore, a complete view of the whole expanse, and there was a dreariness and desolation pervading the scene which strengthened as we gazed upon it."
Under the circumstances, an advance with the main body of the party was considered unwise, and it was determined to launch the boat, and try and follow the course of the river, whilst a simultaneous attempt was made to penetrate the reed bed to the north. Accordingly Sturt, with two men, started in the boat, and Hume and two more struck north.
Sturt's boating expedition came very quickly to a close. In the afternoon of the day he started:—
" … the channel which had promised so well, without any change in its breadth or depth, ceased altogether, and while we were yet lost in astonishment at so abrupt a termination of it the boat grounded."
All search was fruitless, and mysteriously and completely baffled as Oxley had been, so was his successor, and there was nothing for it but to return to camp.
Hume had been more successful. He reported finding a serpentine sheet of water to the northward, which he did not doubt was the channel of the river. He had pushed on, but was checked by another of the seemingly inevitable marshes.
On the 28th the camp was shifted to this lagoon, and the boat was launched once more; without result. The new-found channel was soon lost in reeds and shallows. Forced to halt again, Hume went to the north-east to scout, and Sturt went north-west, each accompanied, as before, by two men. They left the camp on the last day of the year.
After sunset on the first day, Sturt struck a creek of considerable size leading northerly, having good water in its bed. The next day, after passing through alternate plain and brush for eighteen miles, a second creek was found, inferior to the first both in size and the quality of the water; it too ran northerly. Crossing this creek, after a short halt, they travelled through stony ridges and open forest, and at night camped on the edge of a waterless plain, after a hot and thirsty ride; here one of the men, noticing the flight of a pigeon, found a small puddle of rain water that just sufficed them. Next day, the country steadily improving in appearance, they made west by south for an isolated mountain with perpendicular sides, from the top of which Sturt trusted to see something hopeful ahead. He was disappointed, the country was monotonous and level, and no sign of a river could be seen. They camped that night at a small swamp, and next morning Sturt turned back, like Oxley, coming to the conclusion that:—
"Yet upon the whole, the space I traversed is unlikely to become the haunt of civilised man, or will become so in isolated spots, as a chain of connection to a more fertile country; if such a country exist to the westward."
Hume had not returned when the party reached the main camp on the 5th of January; the next day he made his appearance. He reported having travelled, on various courses, about thirty miles N.N.W. over an indifferent country. He had anticipated meeting with the Castlereagh, but had been forced to conclude that that river had taken a more northerly course than Mr. Oxley had supposed. He went westward, and across fine far-stretching plains, but saw no sign of the Macquarie River having re-formed, crossing nothing but small 'reeks or chains of ponds.
Most of the men, including Hume, complaining of sickness, he camp was shifted four miles to the north, on to a chain of ponds reported by Hume. This creek they followed down, when it disappointed them by disappearing in the marsh. Without water, they continued skirting the low country until fatigue compelled them to stop, when, by digging shallow wells in the reeds, they obtained a small supply. From here they made their way by a different route to the hill that had terminated Sturt's late trip, and which he had christened Oxley's Tableland. Here they rested a few days, and Sturt and Hume, with two men, made another excursion westward, but without result.
Their only resource now was to make north to a creek that they had followed down on their way to Oxley's tableland, and see where it would lead them.
On the 31st January they came upon this creek, which was called by them New Year's Creek, now the Bogan, and the next day they suddenly found themselves on the brink of a noble river:—
"The party drew up upon a bank that was from forty to forty-five feet above the level of the stream. The channel of the river was from seventy to eighty yards broad, and enclosed an unbroken sheet of water, evidently very deep, and literally covered with pelicans and other wild fowl. Our surprise and delight may better be imagined than described. Our difficulties seemed to be at an end, for here was a river that promised to reward all our exertions, and which appeared every moment to increase in importance to our imaginations. Coming from the N.E. and flowing to the S.W., it had a capacity of channel that proved that we were as far from its source as from its termination. The paths of the natives on either side of it were like trodden roads, and the trees that overhung it were of beautiful and gigantic growth.
"The banks were too precipitous to 'allow of our watering the cattle, but the men descended eagerly to quench their thirst, which a powerful sun had contributed to increase; nor shall I ever forget the cry of amazement that followed their doing so, or the looks of terror and disappointment with which they called out to inform me that the water was so salt as to be unfit to drink. This was indeed too true. On tasting it, I found it extremely nauseous, and strongly impregnated with salt, being apparently a mixture of sea and fresh water … Our hopes were annihilated at the moment of their apparent realisation. The cup of joy was dashed out of our hands before we had time to raise it to our lips."
Finding fresh feed lower down the river, the party halted for the benefit of the cattle, who, unable to drink the water, soaked their bodies in it. Meantime, although the tracks of the natives were abundant, they looked in vain for any of them. Fortunately, that night Hume found a pond of fresh water, and the party were refreshed once more. The phenomena of the salt river was puzzling to Sturt, though too familiar now to excite wonder; the long continued drought having lowered the river so that the brine springs in the banks preponderated over the fresh water, was of course the explanation, and it is a common characteristic of inland watercourses. The size of the river and the saltness of its water, however, partly convinced Sturt that he was near its confluence with an inland sea; so for six days they moved slowly down the river, finding, however, no change in its formation, until the discovery of saline springs in the bank convinced the leader that the saltness was of local origin.
Leaving the party encamped at a small pool of fresh water, Sturt and Hume pushed ahead to look for more, but without success. Before leaving they were startled, one afternoon, by a loud report like a distant cannon, for which they could in noway account, as the sky was clear and without a cloud. [These strange reports have since been frequently heard, often at the same moment, at places more than a hundred miles apart. The cause is generally ascribed to atmospheric disturbances.]
The advance was now checked, no fresh water could be found on ahead, and their animals were weak and exhausted. Sturt christened the river the Darling, and gave the order to retreat.
As they again approached Mount Harris on the Macquarie, where they
