28th. Steering in a southerly direction, and following along the western margin of a salt lake--most of the way over samphire flats, with thickets intervening, denser than usual--we encamped on a small grassy spot, with plenty of water in granite rocks, called Murrunggnulgo, situated close to the west side of the lake, which I named Lake Monger. The native Jemmy, in company with some of his friends, stayed behind to-day in order to catch opossums, and did not join us this evening. By meridian altitudes of E Bootes, a Coronae Borealis, a Lyrae (Vega), and Aquilae (Altair), Murrunggnulgo is in south latitude 29 degrees 37 minutes 20 seconds. Damparwar bearing about north magnetic. 29th. Moving a little to the west of south for twenty miles, through dense thickets, by far the worst we have ever encountered, and destitute of feed, we reached Bera Bera, a grassy spot with a dry well, where water might be procured. Continuing North 238 degrees East for about five miles, we reached and camped at some granite rocks, with a fine well of water called Wandanno, which I found to be in south latitude 29 degrees 57 minutes 14 seconds by meridian altitudes of Lyrae (Vega) and Aquilae (Altair). From Bera Bera, Mount Singleton bore North 50 degrees 30 minutes East magnetic about fifty miles distant. Jemmy did not put in an appearance to-day, but sent on a native to say he would join us in a day or two. 30th. Travelling about North 212 degrees East magnetic for fourteen miles, over samphire flats, with thickets intervening, we reached a fine grassy spot, with water in granite rocks, called Gnookadunging. Continuing about south for two and a half miles, passed another small grassy spot called Ginbinning; thence in about the general direction of North 210 degrees East magnetic. For about eleven and a half miles, over an immense sand-plain, running as far as the eye could reach to the North-West and South-East, we camped in the centre of it at a spring called Manginie, a sheep station belonging to Mr. James Church. Towards the end of the day Bailey's horse Tommy fairly gave in, and we had great difficulty in getting him to camp, which Mr. Hamersley and I did not reach until an hour after dark. The night was cloudy, and I was unable to get any observations, but luckily at daybreak obtained meridian altitudes of Jupiter, which placed Manginie Spring in South latitude 30 degrees 21 minutes. 31st. Steering about South-South-West for thirteen miles, we reached Cooroo Springs--a fine grassy spot in winter--where we camped, the horses being very tired. For the first seven miles over scrubby sand-plains; thence to Cooroo, over grassy country, with spearwood thickets intervening. Tommy shot a kangaroo this afternoon, which was very acceptable, having had only damper and tea for several days past.
