The result of the rain yesterday was a thick fog this morning, and when we left the camp at 5.50 a.m. we could not see 100 yards, and we traversed the basaltic plain in an east course till 7.0, when the fog cleared away and we found ourselves at the foot of some low rocky hills of basalt, over which we travelled north 70 degrees east. These hills were very rough and stony, but covered with excellent grass. We then entered a basaltic plain, richly grassed and less stony than usual. At 9.30 crossed a basaltic ridge and entered a large valley trending to the north and east; at 10.10 ascended a rocky hill about 150 feet high, and got bearings of the ranges, etc. The country appeared to consist of grassy hills and plains, extending twenty to thirty miles to the north and east. To the south a range of basalt and sandstone hills intercepted the view. Steered east from the hill, and traversed an undulating country, the rocks being basalt, sandstone schist, and jasper; the basalt forming the higher ground, though on the banks of the creek the jasper rested on the basalt. At 2.10 p.m. encamped on a large creek with a gravelly channel twenty yards wide. Fahey obtained a large quantity of mussels from the pools in the creek; they proved an excellent addition to our supper, though rather deficient in flavour. The weather was cloudy, and, though there was an occasional sight of the sun, we could observe neither the commencement or end of the solar eclipse. I was therefore unable to avail myself of it for correcting the longitude. Latitude by e Argus 17 degrees 9 minutes 6 seconds. 6th April. Left the camp at 6.10 a.m. and steered east over a grassy plain; at 7.25 crossed some wide channels from the south-east, forming a large creek; at 8.15 turned south-east and followed the creek till noon. It then turned south, and at 12.15 p.m. we camped at a shallow pool of muddy water. The creek was here divided into several small channels, in which only a few pools of water remained. The whole of the country traversed this day was nearly level, well grassed, and very open. Basalt and jasper are the prevailing rocks. Latitude by Regulus and Argus 17 degrees 15 minutes 45 seconds. 7th April. As the creek appeared to come from the south and not to have a long course, but to rise in the low sandstone ranges which were visible in that direction, it was useless to follow it farther; we therefore steered northwards to intercept any streams which might join the Victoria River lower down its course, and, after travelling over open grassy ridges of basalt for six hours, at 12.25 p.m. camped at a small gully, in which there were some small pools, which appeared to be supplied by springs. The country for five to ten miles to the east of our track appeared open and grassy, basalt being the prevailing rock. RUNNING WATER. FINE PASTORAL COUNTRY. 8th April.
