Another determined effort to cross the range that seemed to defy all the attempts of the colonists was made by quarter-master Hacking, in 1794. The party succeeded in pushing out twenty miles further than any European had been, but their report was unfavourable. They reached the foot of the range, and after climbing over some eighteen or twenty ridges, formed of little else but precipitous rocks, they saw before them nothing but the same savage and inaccessible country. Tier after tier of ranges rose in view, divided by abrupt and impassable chasms and gorges. The only natives they saw fled at their approach, and, saving for the presence of some large red kangaroos, little sign of animal life was met with. Away to both north and south, the same iron range could be traced, showing no prospect of gap or pass, and they returned dispirited. The colonists now began to look upon the Blue Mountains as their western limit, and the extension of settlement in that direction was regarded as chimerical.

The cattle that had escaped from the settlement had, with their usual instinct, wandered on until they had found suitable grazing land on the Nepean, and there had settled down. When discovered they had thriven well, and increased into a small herd. By the Governor's direction they were left unmolested, being but occasionally visited, and their run became known as the Cow Pastures.

Mr. Bass, the bold explorer of Bass Strait, in company with some other gentlemen, visited these pasture lands in 1797, and from Mount Taurus, on the Nepean River, took a straight course to the coast, where a whale boat was sent to meet them. Their .experience was of the usual kind. After leaving the fertile grazing lands appropriated by the cattle, they crossed a succession of barren ridges, gradually growing worse and worse until the sea was reached.

Bass had, before this, attempted to cross the range in 1796. His attempt was of the same character as all the others, failure and disappointment attending his steps, although the endeavour to obtain success was carried through, as might be expected, with his usual untiring energy and contempt for danger. It is sad to think that a career that opened so brilliantly should have been doomed to close miserably in the mines of South America.

Having become partially convinced that there was no high road to be found between Port Jackson and the Chinese Empire, some of the convicts (principally the Irish prisoners) became possessed with the notion that a colony of white people existed three or four hundred miles in the interior, south-west of the settlement. This tale, highly embellished, was sufficient to inflame the imaginations of men condemned to servitude, and panting for liberty. The existing rumour being found out by the authorities, it proved on investigation that so far had this preposterous legend gained ground that written instructions had been issued for guidance to this Arcadia, accompanied with a paper having the figure of a compass drawn on it. The Governor, wishing to save these foolish dupes from the punishment and probable loss of life that would necessarily ensue in carrying out such a wild project, wrote to a magistrate at Parramatta the following instructions. He was to go to Toongabbie, where most of these infatuated men were employed, and, knowing how impossible it would be to reason them out of their belief, he was to inform them that four picked men would be allowed to start out and satisfy themselves of the impossibility of any show of success attending their search, and that in order to ensure their safe return three experienced men would be sent as guides with them.

On receipt of this information so many assembled that stricter measures had to be taken, and sixteen of the number were arrested and sent to Sydney for punishment. Four men were then selected by the malcontents themselves, and were about to depart in search of the supposed colony when a treacherous plot was discovered. A scheme was on foot for a stronger party of convicts to abscond, and these meeting the explorers at a pre-arranged spot, should there murder the guides, and having possessed themselves of their weapons, the prisoners would be at liberty to prosecute their researches alone. Four soldiers were added to the party to resist any attempt of this sort, and on the 14th January, 1798, they left Parramatta in search of El Dorada.

Amongst the men chosen to act as guides was one James Wilson, who had for some time previously been living in the bush with the natives, and had even submitted to his body being marked and scarred after their fashion. On his return from this nomadic existence, he stated that he had traversed the country for nearly one hundred miles in every direction around the settlement, and discoursed at length upon having seen large tracts of open country, and many strange birds and animals, unknown to the settlers. His stories were for the most part discredited, but it was thought that his experiences would be most useful to the party, and he was therefore selected.

Ten days after the explorers left, the soldiers returned with three of the delegates. On reaching the foot of the mountains, where it was arranged that the soldiers were to leave the party and return home, these three men were so thoroughly tired of their quest, and convinced of their folly, that they had begged to be allowed to go back.

On the 9th February the remainder of the expedition reached Prospect Hill more dead than alive. Wilson alone had kept heart, and managed to sustain the flagging spirits of his companions sufficiently to enable them to stagger in to the settlement.

Their report of the surroundings of the colony contained little more than what was already known or guessed at. They described the country passed over as alternating between barren, rocky ridges and spacious meadows. Running creeks had been crossed, and they turned back on the bank of a river which they described as being as large as the Hawkesbury, with level country in view on the opposite side.
