21st. Continued on North-East, and, travelling over the watershed of the Murchison, we followed along a gully running North-East; then, passing some water-holes, travelled on and ascended a small range, from which we beheld a very extensive clear plain just before us. Thinking it was a fine grassy plain we quickly descended, when, to our disgust, we found it was spinifex that had been burnt. We continued till three o'clock, with nothing but spinifex plains in sight. I despatched Windich towards a range in the distance, and followed after as quickly as possible. When we reached the range we heard the welcoming gunshot, and, continuing on, we met Tommy, who had found abundance of water and feed on some granite rocks. We soon unloaded, and were all rejoiced to be in safety, the prospect this afternoon having been anything but cheering. Distance travelled about thirty miles. Barometer 28.22; thermometer 56 degrees at 6 p.m. Cold easterly wind all day. About eighteen miles of spinifex plains. Latitude 26 degrees 0 minutes 53 seconds by Arcturus and e Bootes. 22nd. Did not travel to-day, the horses being tired, and the country ahead did not seem very inviting. Windich found a native spring about a mile to the North-East. This is a very nice spot, surrounded as it is by spinifex. Variation 2 degrees 40 minutes West by observation. 23rd. Continued on North-East for about twelve miles over spinifex plains and sandy ridges. Went on ahead with Windich, and came to a gorge and some granite rocks with abundance of water, and were soon joined by the party. Barometer 28.30; thermometer 60 degrees at 6 p.m.; latitude 25 degrees 53 minutes 52 seconds by Altair. 24th (Sunday). We rested at camp. I was all day calculating lunar observations. Barometer 28.22; thermometer 64 degrees at 5.30 p.m. FRERE RANGES.
