Sept. 19.--We moved our camp to the water-holes at the left bank of the Robinson, about six miles and a half west by north, from the head of the salt-water in Cycas Creek. The longitude of the Robinson is, according to my reckoning, 136 degrees 43 minutes. On our way we again met the natives, men, women, and children, who ran away screaming loudly. I visited their camp again, and found that they had been there to fetch the emu feet; but had left all the other things behind. I went with Brown to examine the country before us. The first three or four miles lay through an open well-grassed forest and over some small plains, on which we gave an unsuccessful chase to three emus. The Cycas disappeared as we receded from the river. We passed a small scrubby creek, and a long tract of stringy-bark forest, mixed with bloodwood and Pandanus, and patches of Cypress pine. Here we again observed the gum-tree with orange blossoms and large ribbed seed-vessels, which we found at the upper Lynd, and had called Melaleuca gum. Sterculia was frequent, and we collected a great quantity of its ripe seeds. We passed several dry swamps, surrounded with tea-tree thickets, and heaps of fresh water mussel shells. A rich iron-stone rock cropped out frequently; its surface had the appearance of having been netted. In a tract of broad-leaved tea-tree forest, we came to a watercourse, which led us to a fine creek surrounded with Pandanus and drooping tea-trees, and containing a chain of deep water-holes in its bed. Its course was from west to east. Sept. 20.--We removed our camp to the creek I had found last night, about nine miles north-west from the Robinson. On our way, we saw two flocks of emus, and Spring caught one of the birds. According to Charley, who is a native of Bathurst, the emus of this part of the country are much smaller than those of his country, which frequently yield from two to three gallons of oil; but very few of the gulf emus contained fat enough to fry their own liver; and their skin was as dry as that of the native dog. A similar difference has been observed in the bustard, which, at the gulf, rarely weighed more than three pounds and a half; whereas individuals of twenty and twenty-eight pounds weight have been shot to the southward. I succeeded here in cooking the seeds of Sterculia, which had recently been gathered; first by separating them from their prickly husks, and roasting them slightly, and then pounding and boiling them for a short time. They produced not only a good beverage with an agreeable flavour, but ate well and appeared to be very nourishing. They contained a great quantity of oil. Brown caught an Agama, of a light yellowish colour, about a foot long.
