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.
ENTER THE VALLEY OF THE MURCHISON RIVER.
25th September.
Started at 8.27 a.m.; passed over poor stony hills of granite formation and producing a little grass in tufts--the wattles growing so close together as to render travelling difficult and tedious. At 10.45 came on a large stream-bed, which had scarcely ceased to run; the channel was fifty yards wide, the bed steep and rocky, and, where crossed, ran over a dyke of trap-rock, the water slightly brackish and in long shallow pools, with samphire on the banks. This stream must be the Murchison River, as no other was passed for 30 miles to the northward; the effects of violent floods were visible, but it did not bear the character of a stream rising at any great distance inland, nor did the nature of the gravel and sand brought down by it indicate a rich soil on its upper portion, as I did not see anything besides fragments of siliceous rock and garnet sand. The valley through which it ran appeared to be five or six miles wide, extending twenty miles to the eastward, backed by sandy plains on both sides; a few patches of grass appeared in the lower parts of the valley; westward it seemed to contract and turn to the south-west, flanked by steep flat-topped hills of sandstone, resting on granite rock. Continuing north-north-east up a small valley, we passed through wattle thickets till 1.40 p.m., when we again ascended the level sandy tableland or plains, and changed the course to the north; the scrub increased in density as we proceeded. At 4.25 halted for the night in a patch of good grass, where the thicket had been burnt off by the native fires; the sandy nature of the soil rendered the search for water unsuccessful; we therefore contended ourselves with the allowance of one pint each.
26th September.
Left the bivouac at 7.15 a.m.; course north; the country more open; 9.25 came on a large native well of good water in a slight hollow trending westward; having watered the horses and filled the kegs, continued our journey over sandy plains, covered with short coarse scrub; many hummocks of loose sand, covered partially with scrub, lay on each side of our track. At noon passed the last sandy ridge; before us lay an immense plain, covered with thickets, and not a hill or valley could be observed--the country seemed to settle into one vast level of dense and almost impenetrable scrub or thicket. At 1 p.m. entered it, and continued our route through it; although the bush-fires, which had burnt some large patches, greatly assisted us; 4.15 not finding any grass, we steered west, but at 5.15 were compelled to halt for the night in a dense thicket, without a single blade of grass or even scrub of any kind which could afford food for the horses; water it was hopeless to look for; and after a supper of raw bacon, damper, and a pint of water each, we retired to rest.
WATERLESS COUNTRY AND DENSE SCRUB NORTH OF MURCHISON RIVER.
27th September.
At 7.0 a.m. set out on a north course; at 8.5, finding the thicket almost impassable, I ascended a cypress-tree, where a most cheerless view met my sight to the north, east, and west; not a break was visible--nothing but thicket in all directions, with scarcely an undulation of any kind; the view to the north-west was most extensive--nearly twenty miles of thicket could be seen, with a surface as level as the sea. Not considering it prudent to proceed onwards, the thicket being too dense to advance without the greatest difficulty, the saddle-bags being almost torn to pieces, and the horses quite worn out with continual exertions in dragging their packs through the thickets, we were compelled to return to the well passed yesterday morning. The country seen to the northwards was of too flat and sandy a character to give any hope of finding water or grass--and without these requisites, it would be incurring great risk of losing the horses, and of course defeating the object of the expedition; therefore, taking advantage of the partially cleared tracts of yesterday, we reached the watering place at 4.30 p.m.
28th September.
This day we employed ourselves in repairing our pack-saddles, which it was found necessary to restuff, as they had been padded with coarse rushes; the saddle-bags had been torn to pieces, and the repairs of these required more time than could be afforded in an evening's bivouac.
29th September.
Started at 8.35 a.m.; pursued a general course of 310 degrees, gradually ascending the sandy downs on the north side of the valley for three miles; it then turned to the north of west, and we again descended, and found the bottom occupied by a narrow samphire flat, 50 to 100 yards wide, over which the water runs during heavy rains, but it was now dry, and in some parts covered with a thin crust of salt; 11.26 passed a native well of slightly brackish water, amongst loose blocks of red sandstone; a small well was passed at 11.50; the samphire flat then changed to a small sandy channel, among large blocks of sandstone belonging to the coal-formation: in one place the slate also cropped out. Abundance of brackish water lay in small pools along the course of the stream-bed, which at 1.0 p.m. changed its direction nearly west; we followed it through a scrubby valley, with high hills on both sides, till 4.45, when we bivouacked just below the junction of a small gully from the northwards, with a very remarkable sandstone hill about three-quarters of a mile south; below this spot the valley trended to the south-west, and was bounded on the north-west by flat-tapped sandstone hills.
30th September.
Not being more than ten to fifteen miles from the sea, I steered north 330 degrees east magnetic. Starting at 8.5, and having ascended the high land, passed through a thick line of wattles and dwarf gum, growing on the eastern face of the limestone range, which forms the high barren range along this part of the coast. The country was covered with thick scrub, and some patches of gum and wattle thicket; about noon it was more open, and ascending an elevated sandy ridge, saw apparently a high range of hills extending north-north-west as far as Shark Bay, and terminated by a very abrupt and detached hill; but the excessive refraction caused by the heated and nearly level plain which intervened more than doubled their real height. We descended gradually over a succession of sandy hills or ridges till 2.0 p.m., when the lowest part of the plain was reached; we found it occupied by a small patch of spear-wood; the soil was hard dry clay, but on proceeding a little farther we found a patch of moist ground, encircled by a ridge of sand; at one foot deep we found water, but in such small quantity that we could only obtain sufficient for ourselves, and should have had to wait at least two hours to have given each horse only one gallon. Proceeding onwards, in hope of finding a more plentiful supply, we found the country became drier and full of circular hollows, filled with fine clumps of green wattle and a little grass; in one of these we bivouacked at 5.0, and dug six feet for water in red sand, but without any appearance of obtaining it even at double that depth.
REPULSED FOR WANT OF WATER.
1st October.
This morning started at 7.55 a.m., and steering north-west, in hope of finding water, at 8.40 came on dense thickets of wattle, which extended at least seven or eight miles farther north; we therefore turned west to avoid them; at 9.30 changed the course to 300 degrees magnetic, and with great difficulty forced our way for two miles to a narrow strip of open ground; 12.40 p.m. arrived at the foot of the range of hills seen yesterday; found them to consist of limestone and sand, covered with thick scrub; between the hills were many nearly circular hollows filled with thickets of wattles; although the bottoms of the hollows were at least fifty feet below the lowest part of the ridges around them, they were quite dry, and afforded no hope of water even by digging; the country northward appeared even less likely to afford a supply, so much required, as it seemed to consist wholly of limestone and loose sand, without swamps or watercourses; the nearest spot at which we could hope to find it in this direction was the south part of Freycinet Harbour, distant, according to the charts, about thirty miles, and great doubt existed of the accuracy of it in this position (error having been found in some other parts of the coast-line); nor was it certain that we could find water on the coast, in which case the loss of our horses would be almost a necessary consequence, several of them showing extreme fatigue. The circumstances of the case required a prompt decision; I therefore ordered an immediate return towards the last spot where we
