such a country is in a regularly wet season) encompassed them, and greatly obstructed their progress. Mr. Hume, whose enterprising disposition was abundantly manifested in his journey to the south coast, which has been already noticed in this paper, was associated with Captain Sturt on this occasion. With such aid, the latter proposed to divide the party, in order to undertake at the same time two distinct excursions, to ascertain more fully the nature and extent of those marshy flats, and set at rest any doubts which might be entertained as to the mode in which that river terminated—that is, of its non-existence in that low country, after the devastating operation of a drought of three years. Accordingly, one party, conducted by Mr. Hume, proceeded in a north-easterly direction, towards the Castlereagh, whilst Captain Sturt himself pursued a course to the north-west.
It would indeed have been most interesting, at this stage of the expedition, had Captain Sturt been provided with good barometers, to have ascertained the mean height above the level of the sea, not only of the lowlands over which the party had so patiently borne the burden and heat of the day, but also of the country which Captain Sturt traversed in his excursion to the north-west, and which he found, 'after travelling between twenty and thirty miles,' began to rise; also his level at the end of his journey, which was extended to an estimated distance of one hundred miles, where he 'made a hill of considerable elevation,' from the summit of which he had 'a view of other high lands;' one in particular to the south-west, which he describes as 'being a very fine mountain;' and which he afterwards visited and found 'of sand-stone formation,' elevated above the 'desert waste' on which it stands, one thousand three hundred feet. Captain Sturt, however, had no barometer on which he could in the least depend; the instrument with which he had been provided on his quitting Sydney, having sustained an injury on the Macquarie, four days before the expedition reached Mount Harris.
The observations made during these short excursions, satisfied the party, that the river had no existence in any shape beyond the 'third marsh' previously explored. Mr. Hume passed from east to west, along the northern skirts of those extensive reedy flats, without either meeting with a further trace of a channel northerly, or finding water enough to supply his daily wants. And the character and direction of those vast flats, as well as the points to which the waters discharged upon them by the Macquarie in seasons of prolonged rains, tend, were now fully determined.
From the report of Captain Sturt's examination of those lowlands, then, affected as they were at the time by drought, these facts may be gathered. At a distance of about twenty-eight
