Monday, 25th August, Purdie Ponds. Started at seven o'clock on my former tracks towards Daly Waters. At seven miles south of the Blue-grass Swamp saw a heavy fog to the east, in the same place that I saw the black fog in coming up; it must be caused by a large body of water in that direction. The natives have been running our tracks, and have burnt the grass on both sides of it for some distance. There seem to be very few of them about this part of the country. At half-past four passed the large swamp that receives the surplus water of Daly Waters, with water still in it, but very much reduced. At a quarter past five o'clock arrived at Daly Waters; found them also very much reduced, but still an abundant supply. Got all the weak horses through, which is more than I expected. This long journey has again completely exhausted me, and I feel very ill. Wind, south-east, with a few clouds. Tuesday, 26th August, Daly Waters. I feel a little better this morning, but still very weak and languid. I shall give the horses and myself a rest to-day, for I am quite unable to ride. Wind, south-east, with a few clouds from the same direction. Wednesday, 27th August, Daly Waters. Last evening, about half-past seven, Thring observed a comet bearing about 20 degrees west of north, and about 15 degrees above the horizon; the tail is short and the nucleus large. I regret that I am unable to see it. I cannot now see a single star, everything at night is total darkness. I should like to take some observations of it, but I am quite debarred from doing so. Started at half-past seven and proceeded along the Daly Waters, in which we saw an abundant supply. On reaching McGorrerey Ponds, and finding plenty of water, camped. I feel a good deal better to-day, but the motion of travelling on horseback is still very severe. Although Daly Waters is much reduced, there is still enough to last six months longer, even should no rain fall. These ponds will also hold out about three months longer. Wind, strong from south-east, with a few clouds. Thursday, 28th August, McGorrerey Ponds. Proceeded to King's Ponds and camped. Find that the natives have been running our tracks, and have burnt large patches of grass; at this camp they have burnt it round. The water here is nearly all dried up; a few days later and I should not have got a drop. There is enough to last me to-night and to-morrow morning. Strong wind from south-east. The natives have cut on one side of my initials, on a gum-tree by the water where we camp, a figure resembling (a stylised flying bird).
