There fortunately was an elevated pinnacle of rocks on the rising ground upon which we were encamped; and from the top of these I was able in the course of the day to get bearings and angles to many important objects; I could also see many fixed points in my survey, so that the day could not be considered as altogether a lost one. CONDITION OF THE PONIES. March 18. Throughout the whole of this day the rain poured in torrents so that the ponies, notwithstanding the goodness of the feed, began again to suffer from cold and exposure to the weather. They were so wild that we could not venture to let them run loose, and, as it was impossible to tether all of them under trees, the majority were left exposed to the pitiless pelting of the storms; and they certainly made a very wretched appearance as they stood with their sterns presented to the blast, and the water pouring from their sides in perfect streams. I do not know whether this was a very extraordinary season, but it is certain that if all rainy periods in North-West Australia resemble it, to attempt to explore the country at this time of the year would be fruitless. Such a good supply of rain is a great advantage to an occupied country through which regular lines of communication exist; as it then raises but slight impediments to travellers; but the case is very different to first explorers who have to find a ford over every stream and a passage across every swamp, and who constantly run the risk of involving themselves in a perfectly impassable region. NATIVES NEAR THE CAMP. March 19. This morning was also ushered in with torrents of rain, chequered by occasional intervals of fine weather of perhaps half an hour's duration. Another sheep died and several of the ponies were very unwell. The men who had been shifting the tethers of the horses at noon returned with the intelligence that, during the period of their absence from the encampment, a party of natives must have been close to us, watching our movements, for that when they went out there were no traces of them near the camp, which were now discernible in nearly every direction around us.
