I have always considered that Eastern and Western Australia were originally separated by the sea; and that when they were thus separated (which the narrow space, and as I conjecture, lowness of the country between the Gulf of Carpentaria and Lake Torrens fully bears out) the habits of what is now the northern side of the continent found their way to the southern. It is true I have in another place conjectured, that in cases where similar habits are found to prevail at widely distant points, they may be looked upon as relics of a former universal state of things, now preserved only in particular localities; yet without invalidating this general rule, I think that the facts of the mode of burial I have described, and likewise the rite of circumcision, existing in the bottom of the Gulf of Carpentaria, and on the south side of the continent, strongly support the opinion that there once existed water communication between them. However this may be, the discovery we had made highly interested the whole party, and suggested the name of Burial Reach for that part of the river. Knowing, or at least feeling, that we were narrowly watched by those into whose territories we had penetrated, I did not venture far inland. In the few miles traversed there was little of interest, except that we felt the pleasure which almost surpasses that created by beauty of scenery, of traversing a country totally new to the European. It is astonishing how charming mere plains covered with clumps of trees appear under such circumstances. But this feeling can be enjoyed but once; for it is the explorer alone who can either experience or deserve it. This part of the country, though to all appearance equally level with any other, was higher, and may perhaps have attained to the elevation of thirty-five feet above the level of the sea. Over the plains were scattered flocks of beautiful rose-coloured cockatoos, several of which I shot; they were precisely the same as those on the southern parts of the continent. Beyond Burial Reach the river separates into two branches, one taking an easterly and the other a southerly direction; but neither of them, unfortunately, was it at that time in my power to explore. Here we again, for the second time only, met with a rocky formation: it was of a red ferruginous character. Our furthest position on the Flinders was in latitude 17 degrees 51 minutes South in a general South by East 1/2 East direction from the entrance, nearly thirty miles by the distance the boats had traversed. MOVE DOWN THE RIVER. After noon observations, the gig moved down the river. On passing the large island, I shot an animal resembling a water-rat, of large dimensions, particularly expanded across the loins, with stout hind legs and palmated feet, of a light slate colour and soft fine hair approaching fur, the colour gradually becoming lighter under the abdomen; the head was flatter than that of the usual tribe of water-rats, and resembled an otter.*
