As this was a suitable camp for resting the party, and grass was abundant, I rode to the south-east with Mr. H. Gregory to look for a route towards the head of the Wickham River; our course was along a valley between the trap hills to the west and a sandstone range to the east. About eight miles reached a creek trending north-east; its channel was dry and sandy, but after some search found a small pool of water in a side channel; casuarina and flooded-gum trees grew on the banks of the creek, and there was some good grass on the flats, which were limited by sandstone hills densely wooded with acacia of the same species as that seen on the lower part of Sturt's Creek. After an hour's halt at the pool of water we returned to camp. SILENT NATIVES. 19th July. The horses having scattered much during the night, it was 8 a.m. before they were collected and saddled; we then followed our track of yesterday to the pool in the creek, eight miles south-east, reaching it at 11.45. The sandstones here showed a decided dip to the west, at angles varying from 5 degrees to 30 degrees, and the trap-rocks only extended five miles from the previous camp. In the afternoon five natives were observed watching the camp, and finding they were observed by us came up to the party, but could not be induced to speak a single word; they soon after retired. They had no spears, and were followed by a small dog. Their teeth were entire, but they were all circumcised. At 8.0 p.m. the blacks were detected stealing into the camp, and, though we called upon them to retire, only hid themselves in the grass; but as it was absolutely necessary for our own safety to dislodge them from their position, I caused a gun to be fired in the air, hoping that they would retire, but they commenced to ship their spears, and I therefore ordered a charge of shot to be fired at them, which had the desired effect of compelling them to retreat. What their object was in thus approaching the camp at night, unless for hostile purposes, we had no means of ascertaining; but the aboriginal Australian considers it an act of positive hostility to approach a camp in silence at night. Latitude by a Coronae Borealis 14 degrees 59 minutes 6 seconds. 20th July. Starting at 7.30 a.m., steered south-east over an undulating sandstone country, well grassed, but very stony and thinly wooded; a low range of rocky hills, nearly parallel to our route, lay to the south-west, and at 11.20 a.m. we camped at a fine running stream in a rocky ravine in this range; the grass was, however, very dry and inferior near the range. Latitude by a Coronae Borealis 15 degrees 4 minutes 31 seconds. 21st July.
