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.
