The expedition, when fully organized, consisted of 15 men and 24 camels, with twelve months' provisions, weighing in all 21 tons. The start was made from Melbourne on the 20th of August, 1860--an imposing spectacle, which has yet left its impression on the memories of many of the older inhabitants of that city. By the committee's direction, they were to march first to the Darling, next to the Lower Barcoo (Cooper's Creek), and then strike northward for the Gulf of Carpentaria. Melbourne had been left too late in the season, and this disadvantage was aggravated by delays occasioned by the unwieldiness of the expedition and insubordination on the part of some of the men. At length Menindie, on the Darling, was reached. The name is new in the history of exploration, but the locality is in the neighbourhood of Laidley Ponds, a quarter which was then well known to the readers of Sturt and Mitchell. Burke formed a depôt here, in which he left the greater part of his men and some beasts of burden to recruit from the fatigues of their toilsome journey. Taking Wills, together with six men and 15 camels, he made his arrangements for a quick journey across to the Barcoo. It had been his intention to follow Sturt's old track, but he was dissuaded from his purpose by a Mr. Wright, superintendent of a neighbouring pastoral station, who told him of a better route further to the north, and volunteered to conduct the party over it in person. Both the advice and the offer were accepted; nor did experience fail to justify the change of plan. Travelling was agreeable on this new route, and water found at intervals of not more than 20 miles. The march from Menindie to Torowotto was little short of a pleasure excursion, and Burke, with the generosity which was part of his nature, now associated Wright permanently with the expedition, giving him the position of third in command. Being no longer needed as a guide, he was sent back from this place to the depôt on the Darling, with orders to bring forward the heavy supplies with all convenient speed. The advance party continued their progress into the interior, and, on the 11th of November, struck the Barcoo, which was followed until a suitable place was found where they might encamp till the arrival of Wright with the remainder of the expedition. The delay proved to be longer than had been expected; and, that the time might not be altogether lost, some explorations were made in the surrounding country, and several promising routes to the Gulf were examined with little satisfactory result. Worst of all, some of the camels were lost, and although much time was consumed in the search, they were never seen again by the explorers. Wright's delay was becoming as vexatious as it seemed to be inexcusable. Six weeks had passed away since he left Burke, and yet the whole distance from Menindie to the encampment on the Barcoo had been traversed by the advance party in twenty-two days.
