The successful and arduous expedition led by the young native-born explorer, had the twofold effect of exposing Oxley's fallacies, and teaching a lesson of caution to future explorers not to indulge hastily in general condemnation. This lesson, however, has not been heeded; the history of Australian exploration being a history of conclusions drawn one year, to be falsified the next. Hume's journey to Port Phillip at once added to the British-Colonial Empire millions of acres of arable land watered by never-failing rivers, with a climate calculated to foster the growth of almost any species of fruit or grain.

It is a pity that in concluding the review of an expedition, fraught with so much benefit to the colony, and carried out with so much courage, hardihood, and facility of resource, that it cannot also be said, and marked with the same cheerful spirit that pervaded those of Oxley's, but unfortunately, the evil feeling of jealously that would arise from the presence of two leaders, showed plainly throughout in petty and undignified squabbles, which, in after days, led to paper warfare between the two explorers. It is painful, if amusing, to read of the disagreement as to their course in very sight of the lately discovered Australian Alps, and how, on agreeing to separate and divide the outfit, it was proposed to cut the tent in half, and the only frying-pan was broken by both parties pulling at it.

Thomas Boyd, the only survivor of the party in 1883, who was then eighty-six years old, was the first white man to cross the Murray, which he did, swimming it with a line in his mouth. In the year named he signed a document, giving the credit of taking the party through in safety to Hume. Boyd himself was one of the most active members of the expedition, and always to the front when there was any work to be done.

The training that Hume received in this, and his former journey, admirably qualified him to become the companion of Sturt in his first expedition when he discovered the other great artery of the Murray system, the Darling. The young explorer was thus singularly fortunate in having his name connected with the discovery of two of the most important rivers in Australia. In the trip just narrated he and his companion, Hovell, had arrested the hasty conclusion that was being formed as to the aridity of the interior. The result of their expedition held out high hopes for any future explorer, and the report they brought in was afterwards fully confirmed by Major Mitchell.

In 1824, in consequence of the favourable report of Surveyor Oxley, a penal settlement was formed at Moreton Bay, but it was speedily removed to a better site on the Brisbane River, where the capital of Queensland now stands. The natives bestowed upon the abandoned settlement the name of "Umpie Bong," [Literally, dead houses] which name is still preserved as Humpybong.

In 1825 Major Lockyer made a long boat excursion up the Brisbane River, and the stream being somewhat swollen by floods, he was able to penetrate, according to his own account, nearly one hundred and fifty miles.

He was much taken with the promising nature of the country, both on the Brisbane and its tributary, the Bremer, and great hopes, happily fulfilled, were entertained of the success of the new settlement. During this year Mr. Cunningham had undertaken another journey to Liverpool Plains. Threading the pass he had formerly discovered and named Pandora's Pass, he crossed the plains, and ascended and examined the table land to the north, returning to Bathurst.

In 1827 this explorer, whose industry never flagged, started on the most eventful trip he ever made, destined to considerably affect the immediate progress of the new colony established at Moreton Bay. On the 30th of April he left Segenhoe Station, on the Upper Hunter, and on crossing Oxley's 1818 track to Port Macquarie, at once entered on the unexplored northern region. On the 19th May, after traversing a good deal of unpromising country, a fertile valley was entered, which led the travellers on to the banks of the Gwydir River, one of Cunningham's most important discoveries. He next found and named the Dumaresque River, and finally emerged on the beautiful plateau, thenceforth known as the Darling Downs, where the Condamine River received its name, after the Governor's aide-de-camp. Cunningham's description of this tract of pastoral country is very glowing:—
