19th February.

Commenced our day's journey at 6.0 a.m., followed the bank of the creek till 8.15, thence south-south-west till noon, when the course was altered to south-south-east to close in with the creek, but found that the channel was completely lost on the level grassy plain, and at 1.40 p.m. encamped at a small puddle of muddy water as thick as cream. Before the creek was lost in the level plain it spread into some large, though shallow pools, which swarmed with ducks of several species, but principally the whistling duck. The grassy plain gradually extended to a greater breadth, and the back country was so nearly level that it scarcely rose above the grassy horizon, while to the south the country was so level that the clumps of bushes appeared like islands, and the grassy plain extended to the horizon. Near one of the waterholes in the creek we surprised a native, who was sitting at his fire with a couple of women, who decamped with all possible despatch. Several smokes have been observed to the south and south-west, which shows that water must exist in that direction, though it may not be in sufficient quantity to supply our horses. The morning was cloudy, and at midnight there was a heavy shower of rain. Judging from the general appearance of the country, the waters of the creek, after spreading over the plain, must escape to the westward, as the grass has been bent in that direction by the current last year, but there has been so little rain this season that the channel of the creek has not been filled.

As it appeared that the waters of the creek trended to the west in the wet season, at 6.5 a.m. we steered north 250 degrees east, through a level forest of box-trees, with abundance of good grass; the soil brown loam with fragments of limestone; the shower last night had left many shallow pools of water on the surface. At 8.40 a.m. passed a small swampy salt flat covered with salicornia; at 9.10 came on the grassy plain which we skirted on a west course, but as it turned to the north-west, again changed the course to 320 degrees; the plain was now reduced to about a mile in width, and we therefore crossed it in search of a definite channel, but without success, though there were some slight indications that during inundation the water flowed to the north-west. At 11.50 we camped at a shallow puddle of rainwater, on the north side of the plain. From the camp, till 8.0 a.m., the grass, though very backward, showed that there had been sufficient rain to cause it to spring; but as we proceeded it was perfectly dry and parched up, as at the end of the dry season, showing that little or no rain had fallen for many months in this part of the country. The day was cloudy, with thunder, and was followed by a heavy shower at night, which prevented my ascertaining the latitude by observation.

ENTER WESTERN AUSTRALIA.

21st February.

As we were now three days' journey from the last water which could be depended on for more than a few days, and the channel of the creek had been so completely lost on the plain that it was uncertain whether the marks of inundations near this camp had been caused by the creek flowing to the west, or by some tributary flowing to the east, I determined to attempt a south-west course, in the hope that, should the country prove rocky, the heavy showers might have collected a sufficient quantity of water to enable us to continue a southerly route, and accordingly selected the most prominent point of the rising ground to the south of our position, and at 6.5 a.m. started north 235 degrees east. After leaving the open plains we entered a grassy box forest, which continued to the foot of the hills, which we reached at 8.0. The slope of the hills proved very scrubby, with small eucalypti and acacia, the soil red sand and ironstone gravel; at 9.0 reached the highest part of the hills for many miles round. To the south the country was slightly depressed for ten or fifteen miles, and then rose into an even ridge or plain, the whole country appearing to be covered with acacia and eucalyptus scrub. To the west and north the view was more extended; the low ridge of sandstone hills extended to the west-north-west, on the northern side of the grassy flats for thirty miles, and only broken by a large valley from the north. Throughout its whole extent this range appeared to rise to 150 or 200 feet above the plain, and had the appearance of being the edge of a level tableland. South of the grassy plain, the western limit of which was not seen, the country rose gradually to eighty or 100 feet, and presented an extremely level and unvaried appearance. It was evident that our only chance of farther progress was to follow the grassy plain to the west till some change in the country rendered a southerly course practicable, it being probable that some creek from the north might join the grassy plain, and that the channel which had been lost might be reformed. At 9.30 steered north-west, and at 12.30 p.m. cleared the acacia scrub, and at 1.30 reached the bank of the creek, which had formed a channel twenty yards wide, with pools of water, which was brackish; but we were too glad to find any water which we could use without detriment to object to it because it was not agreeable in taste, and therefore encamped. We have thus been a second time compelled to make a retrograde movement to the north after reaching the same latitude as in the first attempt to penetrate the desert; but I did not feel justified in incurring the extreme risk which would have attended any other course, though following the creek is by no means free from danger, as very few of the waterholes which have supplied us on the outward track will retain any water till the time of our return. The weather was calm and hot in the early part of the day, and in the afternoon it clouded over, and there was a slight shower of rain. According to our longitude, by account, we have this day passed the boundary of Western Australia, which is in the 129th meridian.
