At 6.5 a.m. resumed our search for water, and following the creek north-east for two hours reached a small muddy pool of rainwater, at which we encamped. The country near the creek was very level, and thinly-wooded low hills were visible in the distance to the south-east and north. Latitude by a Trianguli Australis 16 degrees 16 minutes 25 seconds. 3rd August. The water at this pool near our camp being nearly consumed, and nothing but thick mud remaining, we proceeded down the creek in search of a better supply; but it was not until we had followed its dry sandy bed for three hours that we attained our object, and encamped at a small pool in one of the back channels, the principal bed of the creek being perfectly dry. The country near the creek continues very level, and well grassed, but distant rocky hills are visible in almost every direction. In approaching the Gulf of Carpentaria heavy dews and fogs have become more frequent in the mornings, when it is usually calm. About 10.0 a.m. a breeze usually sets in from the eastward, varying from north to south-east; at sunset it falls calm, but commences again at 8.0 p.m. and blows moderately from the eastward for one or two hours; very thin misty clouds are frequent, and render the heat oppressive when they prevail. According to my reckoning, we are now only fifty miles from the sea-coast, and therefore much nearer Dr. Leichhardt's track than I could wish to traverse the country; but, however desirable a more inland route might be, it is evident, from the small size of the watercourses hitherto crossed, that we have been skirting a tableland which is doubtless a continuation of the desert into which we followed Sturt's Creek, and the small altitude of the country in which the watercourses trending towards the Gulf take their rise precludes the existence of any considerable drainage towards the interior. Latitude by a Trianguli Australis 16 degrees 14 minutes 45 seconds. THE MCARTHUR RIVER. 4th August.
