"Thus, after having followed Sturt's Creek for nearly 300 miles, we have been disappointed in our hope that it would lead to some important outlet to the waters of the Australian interior; it has, however, enabled us to penetrate far into the level tract of country which may be termed the Great Australian Desert." Gregory, convinced that no useful results could arise from any attempt to penetrate the inhospitable region to the south, determined to return before the rapidly-evaporating water on which they were dependent should vanish and cut off all retreat. He therefore retraced his steps up Sturt's Creek, and on the 28th of March arrived at his temporary depot, where he found the men all well and the horses much improved in condition. On the 2nd of April, A.C. Gregory, taking his brother Henry, Baines, and one man, started on an excursion to examine the eastern tributaries of the Victoria, and was absent a little over a fortnight. On their return, the whole of the members started for the landing-place on the Victoria, which they reached on the 9th of May. After all arrangements and preparations had been completed, Gregory, with most of the party, started on the return journey overland to Moreton Bay.
