The scarcity of water and the very level appearance of the country to the northward of our bivouac, added to the general denseness of the thicket of acacia and cypress, rendering a continuance of a north course unadvisable, we steered north-west from 8.30 a.m. till noon, when we ascended a scrubby sand ridge, from which we had an extensive view; neither hill nor valley could be discovered to the north, east, or west--nothing but one immense sea of dense thicket of acacia and cypress was visible in these directions; the course was therefore changed to west, and continuing it without much alteration over a succession of low ridges of drifted sand, the valleys being filled with dense thickets, until 6.20 p.m., when the approach of night compelled us to bivouac in a small patch of gum forest, which also afforded a few scattered tufts of grass for our horses. Although this was the lowest spot passed in a distance of more than ten miles, it was so completely dried up and parched that a search for water was fruitless, even by digging; the scanty allowance of very brackish water in our kegs was therefore much relished by the party. 22nd September. The night having been cloudy, and a strong breeze preventing any dew, our horses were not much refreshed; we, however, started at 7.45 a.m., and steering nearly west till 3.15 p.m. through a succession of dense thickets, high scrubs, and thorny bushes, we entered open sandy downs, and changed the course to south-west, with the intention of making the Hutt River, should we not find any water nearer, when, almost hopeless of procuring this essential element before the next day, we unexpectedly came to a native well in the centre of the sandy plain; here we bivouacked at 5.40, but, from the loose sandy soil in which the well was dug, we could not obtain more than about two and a half gallons of water for each horse, the sides of the well continually falling in. Strong breeze from the north-west, and several light showers in the evening and night. 23rd September. Having completed watering the horses, we left the well at 9.30 a.m., and steering about north-west over undulating sandy downs, covered with coarse scrub and patches of dense thickets, at 2.15 p.m. entered a small gully trending north-west. The country improved, but was so thickly clothed with wattles as to render travelling difficult; a few patches of grass were seen in some small watercourses, in which a little water remained. At 4.40 bivouacked on a large gully trending northwards, with several small pools of water in a rocky bed of gneiss, containing numerous small garnets. Strong breeze from the north-west and slight showers. 24th September (Sunday). Although the feed for the horses was not very abundant, yet the long marches they had encountered the last few days made it expedient to give them a day's rest to recruit their weary limbs. Read prayers. Strong breeze from the north-west and slight showers during the day.
