Sept. 5.--We travelled about ten miles west by north, to lat. 16 degrees 48 minutes 22 seconds. Having passed a rather open forest of bloodwood, apple-gum, and leguminous Ironbark, with isolated patches of scrub, and some dry teat-ree swamps with heaps of calcined mussel-shells, we came to a thick stringy-bark forest, on a sandy soil, with a hard sandstone cropping out frequently. This opened into the flats of a sandy Pandanus creek, which we crossed; and, three miles farther, we came to another broad creek with salt water. Its bed was rocky, and we forded it easily. I followed one of its branches for several miles, and found, after passing its salt-water pools, a small pool of fresh water in its rocky sandy bed, near which I observed an old camping place of the natives. I was considerably in advance of my train, and the dog was with me. As I was examining the pool of water and the numerous tracks round it, an emu came walking along the shady bed of the creek; I immediately mounted my horse and pursued it with the dog, and caught it after a very short run; to prevent its wounding the dog, I dismounted to kill it, when my horse became frightened, broke loose, and ran away. I returned with the emu to the water, and when the train arrived, I sent Charley after the horse, whilst I walked about two miles further up the creek to find a better supply of water. Not succeeding, however, I returned and encamped at the small pool, which we enlarged with the spade, and obtained a sufficient supply of very good water. Charley returned with the horse, but my saddlebags, my journals and a calabash were lost. I was in great anxiety, and blamed myself severely for having committed such an act of imprudence. Charley went, however, a second time on foot, and succeeded in finding everything but the calabash, which was a great loss to our dog. In the camping place of the natives, I found a large round stone of porphyry, upon which the natives were accustomed to break the seed-vessels of Pandanus. I could discover no indications of this rock in the creek, not even the smallest pebble; and I am consequently inclined to think that this stone was brought by the natives from a considerable distance to the south-west. But, from the broken pieces of granite of our last camp, it became evident that a rocky primitive country, like that of the upper Lynd, could not be very distant. Even the vegetation agreed well with that of the same locality; as the dwarf Grevillea, G. chrysodendrum, and the falcate Grevillea of the upper Lynd, were here again observed. The tea-trees along the banks of the creek, as far as the salt-water extended, were leafless and dead. This may be accounted for by a succession of dry years in which usual freshes have not taken place; and by the supposition that the drooping tea-tree cannot live on water entirely salt.
