August 30.--A day of rest and refreshment to ourselves and horses. Game abounds, and our dogs abundantly supply us. The observations made here, place our situation in lat. 31. 7., long. 150. 10. E. August 31.--We were agreeably disappointed, in finding that the wet marshy ground did not extend above three quarters of a mile, the remainder being dry firm land of the richest description: at six miles we crossed a considerable stream, running to the north through Barrow's Valley: this stream, divided the plain into nearly two equal parts, it being ten miles and a half across. This stream had been very recently flooded, and the water, yet muddy, had not subsided within its proper level; the height of the banks from fifteen to twenty feet. On the east side of the plain, we found the marsh extend about one mile and a quarter from the forest ground which borders it; though wet, it was now strong ground, and might easily be laid dry. On quitting the plains we entered a very fine open forest flat, through which we proceeded a mile and a half, and encamped for the evening under a lofty hill named Mount Dundas, by a small spring of excellent water. Ascending this mountain, we found that the country in the line of our course was high, broken forest land, the easternmost ranges of which (distant from thirty-five to forty miles) appeared to have a stream running under them, by reason of the thick haze which rose from the valley beneath. To the north bending round to the north-east, the country was beautifully picturesque, consisting of low, open forest hills, bounded by higher chains of hills that formed the southern side of the spacious valley under Hardwicke's Range; through which I no longer doubted that a considerable stream had its course, since all the waters we had hitherto crossed ran in that direction. A great many smokes, arising from the fires of the natives, were seen to the north-east and north. To the south-east, south, and south-west, our view extended over that vast tract of level champaign country intermingled with hills, sometimes rising into lofty peaks, as has already been described. The abundance of game, such as emus, and kangaroos, and of wild ducks on the stream, was wonderful: our dogs after severe battles killed two emus, who however tore one of them very dangerously. We called the river which divided and watered the plain Field's River, in honour of the Judge of the Supreme Court.
