At 6.0 a.m. left the camp, and steered an average west-north-west course over an undulating grassy country of basaltic formation; at 11.45 reached the bank of the creek, which formed fine pools fifty yards wide, with fine open grassy country on both sides, well suited for stock. Followed the creek west till 1.5 p.m., when we crossed to the left bank and encamped. Latitude by Regulus and Argus 16 degrees 59 minutes. 9th April. Continued our route down the creek in a northerly direction, leaving the camp at 6.15 a.m., and at 7.55 reached its junction with the Victoria. The river had high banks and formed deep reaches of water, with a dense growth of pandanus, melaleuca, flooded-gum, and other trees in the dry portions of the channel; the country on both banks was basaltic, and rose gradually into fine grassy downs; the soil very stony, but a good dark loam; sandstone showed where the river had cut through the basalt, which is not of any great thickness. At 2.35 p.m. camped on a back channel of the river, as the principal channel was difficult of access from the steep bank and dense growth of reeds. Although the upper part of the Victoria had long ceased to run, this part of the river was flowing with a strong stream ten yards wide and six feet deep. Latitude by Regulus and Argus 16 degrees 45 minutes 30 seconds. 10th April. Continued our route at 6.5 a.m., and followed the river northward till 8.10, when it turned to the north-west; the country consisted of nearly level grassy plains of various elevations, separated by low rocky ridges of sandstone and basalt, the whole well grassed, except some small patches where triodia prevailed; at 11.0 altered the course to average north-west by west, and at 1.30 p.m. camped at a small gully with a little water remaining from a recent shower. The horses suffered much from the heat, as the air was very moist; at 1.40 there was a shower of rain, and the temperature was reduced from 95 degrees to 84 degrees. Latitude by Vega 16 degrees 35 minutes 8 seconds. 11th April. Started from the camp at 6.30 a.m., steering west-south-west; at first sandstone prevailed, and triodia replaced the grass, but at two miles again entered the basaltic country, which was well grassed but very stony, and forming flat-topped hills of small elevation; the basalt appeared to be interstratified with sandstone, the latter much altered at the line of contact. At 9.15 came on the bank of the river, which was running in a deep channel with a dense line of pandanus, fig-trees, terminalia, flooded-gum, and melaleuca; followed the valley of the river to the north-west till noon, and camped at the foot of the hill which we had ascended, at the most southern point attained in December, 1855; ascended the hill and took the bearings, as on the former occasion the rain had obscured the features of the country. Latitude by Leonis and Argus 16 degrees 27 minutes 30 seconds. 12th April.
