Nov. 25.--We travelled about seven miles and a half N.W. by W., to lat. 13 degrees 0 minutes 56 seconds. I intended to follow the sandy bergue of the river, but a dense Pandanus brush soon compelled us to return, and to head several grassy and sedgy swamps like those we passed on the last stage. Chains of small water-holes, and Nymphaea ponds, ran parallel to the river; and very extensive swamps filled the intervals between rather densely wooded ironstone ridges, which seemed to be spurs of a more hilly country, protruding into the valley of the river. Some of these swamps were dry, and had a sound bottom, allowing our cattle to pass without difficulty. Others, however, were exceedingly boggy, and dangerous for both horse and man; for Charley was almost suffocated in the mud, in attempting to procure a goose he had shot. The swamps narrowed towards the river, and formed large and frequently rocky water-holes, in a well defined channel, which, however, became broad and deep where it communicated with the river, and which in many places rivalled it in size. A belt of drooping tea-trees surrounded the swamps, whilst their outlets were densely fringed with Pandanus. The Livistona palm and Cochlospermum gossypium grew on the ridges; the tea-tree, the stringy-bark, the leguminous Ironbark and Eugenia were useful timber. The whole country was most magnificently grassed. A Porphyritic sienite cropped out at the head of the first swamp, about a mile from our last camp. We had cut our rifle balls into slugs, with which Charley and Brown shot three geese (Anseranus melanoleuca, GOULD). A low range was seen at the south-east end of the large swamp on which we encamped.
