Routes of Sturt (1829 and 1830); and Hume and Hovell (1824).

To Sturt and his companions, who were the first white men to face the interior during a season of drought, the scene may not have seemed too highly-coloured; but, in common with many of Sturt's graphic word-pictures, his description applies only to special or rare circumstances.

In 1828, no rain had fallen for two years, and even the dwellers on the coastal lands began to despair of copious rainfalls. Whenever their glance wandered over their own dried-up pastures, men's thoughts naturally turned to that widespread and boundless swamp wherein the Macquarie was lost to Oxley's quest; and many saw in the drought a favourable opportunity to discover the ultimate destination of these lost rivers. An expedition to the west was accordingly prepared in order to solve the problem under these very different existing circumstances, and Sturt was selected as leader. To Hamilton Hume was offered the position of second in command, and, as the dry weather had brought all farming operations to a standstill, he was able to accept it. Besides Sturt and Hume, the party consisted of two soldiers and eight prisoners, two of the latter being taken to return with despatches as soon as they had reached the limit of the known country. They also had with them eight riding and seven pack-horses, and two draught and eight pack-bullocks. A small boat rigged up on a wheeled carriage was also taken; but like many others carried into the interior, it never served any useful purpose.

The country was by this time well-known, and partly settled up to and below Wellington Vale; but when Sturt reached Mount Harris, Oxley's former depot camp, he had come to the verge of the unknown, and halted in order to consider as to his immediate movements. He consulted with Hume, and as there seemed to be no present obstacle to their progress, it was determined, as Sturt writes, "to close with the marshes."

This they did much sooner than was expected, for at the end of the first day's march their camp was set in the very midst of the reeds. A halt for a couple of days was made, whilst Sturt prepared his despatches to the Governor. On the 26th, the two messengers were sent off to Bathurst, and the progress of the party was resumed. Before the day closed, they found themselves on a dreary expanse of flats and of desolate reed beds. The progress of the main body was thus suddenly and completely checked, and Sturt decided to launch the boat and with two men endeavour to trace the course of the river, while Hume and two others endeavoured to find an opening to the northward.

The boat voyage soon terminated, for Sturt was as completely baffled as Oxley had been. The channel ceased altogether, and the boat quietly grounded. Sturt could do nothing but return to camp and await Hume's report. All search for the lost river proved vain.

Hume had found a serpentine sheet of water to the north which he was inclined to think was the continuation of the elusive Macquarie. He had pushed on past it, but had been checked by another body of reed beds. It was decided to shift camp to this lagoon and launch the boat once more; but without result, for the boat was hauled ashore again after having vainly followed the supposed channel in amongst reeds and shallows. Again the leader and his second went forward on a scouting trip. Each took with them two men; Sturt going to the north-west, and Hume to the north-east. They left on the last day of December, 1828.

Sturt toiled on until after sunset he came to a northward-flowing creek, in which there was a fair supply of water. Next day their course lay through plains intersected with belts of scrub, and they discovered another creek, inferior to the last one both in size and the quality of the water. They camped for a few hours on its bank, and Sturt called it New Year's Creek, but it is now known as the Bogan River. They were about to pass that night without water on the edge of a dry plain, when one of the men had his attention drawn to the flight of a pigeon, and searching, found a puddle of rain water which barely satisfied them. An isolated hill with perpendicular sides, which Sturt had noticed for some time, now attracted his attention, as being a lofty point of vantage from which to get an extensive view to the west. They accordingly made for it, over more promising country. They reached the hill which Sturt called Oxley's Tableland, but from its summit he saw nothing but a stretch of monotonous plain, with no sign of the long-sought river. That night they camped at a small swamp, and the next morning turned back, Sturt agreeing with Oxley, but without as much reason, that "the space I traversed is unlikely to become the haunt of civilised man." Hume did not return until the day after Sturt's arrival. He reported that the Castlereagh River must have suddenly turned to the north below where Oxley crossed it, for he had been unable to find it. He had gone westward, but had seen nothing except far-stretching plains. After a few aimless and unprofitable ramblings, they made their way again to Oxley's Tableland, and Sturt and Hume, with two men, made a journey to the west, with only a negative result. On the 31st of January they commenced to follow down Sturt's New Year's Creek, and the next day, to their unbounded surprise, came upon the bank of a noble river. From its size and width they judged they had struck it at a point as far from its source as from its termination; but when the men rushed tumultuously down the bank to revel in the water and quench their thirst, they cried out, with disgust and surprise, that the water was salt.

Poor Sturt, whose heart was bounding with joy at the realisation of his fondest hopes in this important discovery of a river which seemed to answer all men's dreams and anticipations, felt the sudden revulsion of despair. One saving thought he had, and that was that they were close to its junction with the inland sea. Meantime, although human tracks were to be seen everywhere, they saw none of the aborigines. Hume at length found a pool of fresh water, which provided them with water for themselves and their stock.
