Having decided upon ridingon a head of my party to reconnoitre, as soon as the WATERWITCH should arrive, I at once commenced my preparations, and made the overseer put new shoes on the horses I intended to take with me. The very stony character of the country we had been lately traversing and the singularly hard nature of the stone itself, had caused the shoes to wear out very rapidly, and there was hardly a horse in the teams that did not now require new shoes; fortunately we had brought a very large supply with us, and my overseer was a skilful and expeditious farrier. At dusk a watch was set upon one of the hills near us, to look out for signals from the WATERWITCH in the direction of Spencer's gulf, but none were seen. July 4.--Whilst writing in my tent this evening, my attention was attracted by the notes of swans, and upon going out I perceived a flight of several of the black species coming up from the southward; when they had got over the tents, they appeared to be alarmed and wheeled to the eastward, but soon returning, they took a nearly due northerly course. This was encouraging for us, and augured well for the existence of some considerable body of water inland, but we hoped and expected that a few days would perhaps give us a clue to the object of their flight. Sunday, July 5.--A day of rest to all. In the afternoon I employed myself in writing out instructions for the overseer during my absence, as also for the master of the WATERWITCH, for whose arrival we now kept a constant and anxious look out. In the evening about eight o'clock the sentinel on the hill reported a fire on the opposite side of Spencer's gulf. Upon receiving this intelligence I had blue lights exhibited, and rockets fired, which in a little time were replied to by rockets from the gulf and the lighting up of a second fire on shore assuring me at once of the safe arrival of the cutter.

July 6.--BEING anxious to pursue my explorations, and unwilling to lose another day solely for the purpose of receiving my letters, I sent down my overseer to arrange about getting our stores up from the vessel, which was about fourteen miles away, and to request the master to await my return from the north, and in the interval employ himself in surveying and sounding some salt water inlets, we had seen on the eastern shores of the gulf in our route up under Flinders range.
