Chapter X: Part 10

The night was fine, with heavy dew, the temperature 73 degrees at sunrise; having collected the horses and saddled at 6.45 a.m., left the camp and followed the valley of the river on an average south-west course, crossing a large creek from the north-west; the valley of the river expanded to three miles and then narrowed to one mile, and the course of the river was nearly west till 10.50 a.m., when we encamped; the soil of the valley is a brown loam, producing abundance of grass; but the hills, though less rocky, are more barren than lower down the river; the character of the channel of the river has altered, and has the appearance of a stream which continues to run late into the dry season, as the channels are narrow and fringed with pandanus, melaleuca, and other trees which grow near permanent water; the banks are of less height and the timber on them grows to a greater size than lower down the valley; at 1.0 p.m. the thermometer 100 degrees, and the wet bulb 76 degrees, indicating 24 degrees of evaporation.

CROSS THE WICKHAM RIVER.

20th January.

Left the camp at 6.55 a.m. and followed the river in a west-north-west direction till 8.5, when we crossed at a ledge of rocks which caused a fall of about one foot, the water being twenty yards wide and one to two feet deep; but above and below the rapid the river formed fine reaches seventy yards wide; the course was now west-south-west till 9.0 a.m., when the river turned west, and at 10.50 came to a large stony creek from the south-west, at which we encamped; the country on the banks of the river rises gradually as it recedes, and, except within the influence of the floods, is poor and stony, producing little besides a sharp grass (triodia)--this is the spinifex of some Australian explorers--a few small gum-trees and bushes. As we progress towards the interior the wet season appears to have been of less duration and the fall of rain less, yet the great heat has forced the vegetation towards maturity, and many of the grasses have already ripened their seeds, while there are many other indications of the dry season having fairly set in; the wind is steadily from the south and south-east, and is very dry; the sky is clear and bright, and the creeks have ceased to run; the almost total absence of birds or animals shows that we are approaching the limits of the dry summer season of the southern interior; in the afternoon rode out with Mr. H. Gregory to examine the country, and found that the river came through a gorge in the sandstone range; this gorge is two miles long, a quarter of a mile wide, and 400 feet deep, with nearly perpendicular sides, the winter channel of the river occupying nearly the whole breadth, and intersecting the otherwise flat bottom of the valley with dry sandy channels and long pools of water; beyond the gorge the valley opened, but the view was intercepted by hills.

A HORSE KILLED.

21st January.

Resumed our journey at 7.10 a.m., and, following the right bank of the river nearly west through the gorge, at 9.0 entered an open valley, through which the river came from the south-west; but at 10.0 we entered a second defile, which, from the inclined strata of sandstone, was almost impassable for the horses. In crossing some soft ground between the rocks one of the horses fell on a sharp stump, and was deeply wounded in the belly. The wound was sewn up; but the injury was so severe that the horse died in the night. Having extricated ourselves from this ravine, we encamped at the foot of a sandstone hill, the strata of which dipped 60 degrees to the south-west. Ascending the hill, which was about 300 feet high, the country appeared more level to the south, rising into sandstone ranges at ten miles distance. The course of the river was from west-south-west, the channel being bounded by sandstone cliffs 100 to 200 feet high. The general aspect of the country was wretched in the extreme, as little besides a few small gum-trees and triodia clothed the rugged surface of the red sandstone. The weather continues fine, with only an occasional cloud or flash of lightning in the early part of the night. The temperature is increasing, being 104 degrees at 1.0 p.m. Some catfish and a small tortoise were caught in the river.

22nd January.

At 7.0 a.m. continued our route up the river; but, to avoid the deep ravines on its banks, made a sweep to the south, and at noon encamped in a grassy flat on the bank of the river. The country traversed was very barren and rocky, and the horses had great difficulty in crossing the deep ravines; many of their shoes were torn from their feet during the day's journey. The highest ridge crossed was 500 feet above the bed of the river, the height of which is approximately 500 feet above the sea-level, and thus the general level of the tableland may be considered to be 1000 feet above the sea. The general course of the river being from the west, it appears advisable to reconnoitre the country to the south.

Latitude by Capella 16 degrees 47 minutes 58 seconds.

RECONNOITRE TO THE SOUTH.

23rd January.

Leaving the camp in charge of Dr. Mueller, at 6.30 a.m. started in a southerly direction, accompanied by Messrs. H. Gregory and Baines, taking with us four horses and six days' rations, etc.; after clearing the deep rocky gullies near the river, we passed over a more level country with some fine open plains covered with fine grass, but the intervening ridges were very stony; at 9.45 a.m. reached the highest part of the range, and the country declined to the south-east, and intersected by deep rocky ravines trending towards a large valley, which is probably drained by the southern branch of the Victoria; the course was now south-east, descending to the valley of a creek, through a very barren and rugged sandstone country, producing little besides stunted eucalypti, acacia, and triodia. At 11.15 a.m. halted at the creek, and resumed our route at 3.0 p.m., and followed the valley to the south-east till 4.40 p.m., when it turned east through a rocky gorge between cliffs 150 feet high; but notwithstanding the dense bush of pandanus, fallen rocks and deep muddy channel of the creek, we succeeded in forcing our way through the gorge of the creek, and bivouacked in the open valley below at 5.30 p.m., there being a fine patch of grass in the flat, though the surrounding country is rocky and barren. The sandstone rocks show a great disturbance and dip at all angles and directions, so that no general angle or strike could be determined; the upper rocks, however, show a new feature in a coarse conglomerate of fragments of the lower sandstones and a few fragments of basalt; some of the enclosed pieces of rock are nearly a foot in diameter, and are mostly angular, though occasionally round; this rock forms a horizontal bed of 100 feet in thickness. Towards evening the sky was clouded, with lightning to the east, but no rain.

BASALTIC PLAINS.

24th January.

At 6.0 a.m. crossed the creek, and steered south-east over broken sandstone ridges till 8.0, when we entered a plain of basaltic formation covered with good grass, and where the ground was not entirely composed of fragments of rock the soil was a rich black loam; crossing the large creeks trending north, at 10.0 a.m. halted on the second. These creeks appear to rise in a steep range of sandstone hills which bound the basaltic plains to the west, about two miles from our track. At 3.0 p.m. resumed our route and traversed the trap plain for one and a half hours, and bivouacked in a small gully; the country on both sides of our track seems to be of trap formation for several miles, and then rises into sandstone hills with flat tops. The basaltic rock of this plain is not of great thickness, as the sandstone rose in a few spots above its surface and formed small islands covered with coarse vegetation, surrounded by the open grassy plain. The basalt seems to have been poured out into the valley after it had been excavated in the sandstone, and not to have been much disturbed subsequently. The surface of the plain is very stony, and the horses' feet were much injured by the roughness of the rock.

STONE SPEAR HEADS.

25th January.

The night was cloudy, and it was not till after daybreak that I could get observations for latitude by altitudes of Venus and b Centauri. At 6.5 a.m. were again in the saddle, and steered south-east to a rocky hill, which we reached at 7.0; the hill was sandstone, rising about 150 feet above the trap plain; from the summit the view was extensive, but from the broken nature of the country to the east nothing could be traced of either the courses of creeks or rivers; to the south the trap plain rose to a greater elevation than the summit of the hill we were on, and was surmounted by table hills of sandstone at ten miles distance to the east and north-east; the country appeared to consist of plains of basaltic formation, well grassed, and very thinly wooded. Leaving this hill at 8.0, followed a dry rocky creek to the east and north-east, through basaltic plains with sandstone hills and ridges, till 10.30, and halted during the heat of the day. At this place the bed of the creek had been cut through the basalt into the sandstone, exposing a fine section of the junction of the two rocks; the sandstone was much altered at the line of contact, and, having been deeply cracked, the basalt had filled the fissures of the older rock. This altered sandstone and also a white quartz-like rock are much used by the natives for the heads of their spears; and during this day's journey great quantities of broken stones and imperfect spear heads were noticed on the banks of the creek. At 3.45 p.m. recommenced our journey, and proceeded down the creek to the north-east till 6.30, and bivouacked.

Latitude by Capella, Saturn, and Canopus 17 degrees 24 seconds.

ROE'S DOWNS.

26th January.

Having ascertained that the party could be moved across the range to the basalt plains with advantage, commenced our return to the camp by a westerly route across the plain, which rose gently for ten miles, and was well grassed, but thinly wooded; the soil was stony, with fragments of altered sandstone and basalt. On the higher part of the plain there were several hills of trap-rock, forming flat-topped ridges trending north and south; the highest of these we named Mount Sanford, and the plains Roe's Downs. The country now generally sloped to the bank of the creek near the western limit of the plain, at which, after six hours' ride, we halted at 11.35. The banks of the creek are of trap-rock; but the sandstone is exposed in the bed; the pools of water are deep and apparently permanent. At 4.0 resumed our route and passed over about one mile of sandstone, and then two miles of basalt, and bivouacked at a small gully at the western limit of the valley.

27th January.

At 5.30 a.m. steered north-north-west, over several ridges of sandstone, till we struck our outward track, which we followed with some deviations to the camp, which was reached at 2.0 p.m. The evening was cloudy with a smart thunder-shower. Dr. Mueller informed me that he had traced the river about six miles to the west-south-west, but that beyond that point it appeared to come from the north-west, in which direction there was a low range of hills.

28th January.

Having collected the horses, at 7.15 a.m. steered south to the rocky creek, and followed it down to the rocky gorge and encamped. As the valley was completely walled in by steep rocks, it appeared to be a suitable spot for a depot camp, as it would prevent the horses from straying; and, from the rapidity with which the water in the creeks was drying up, it became desirable that no time should be lost in pushing to the head of the Victoria while it was practicable to cross the ranges in which it was supposed to rise; but as many of the horses were quite unfit for the journey, it became necessary to leave them in some convenient spot while a small party pushed on with a light equipment.

FORM A DEPOT CAMP.

29th January.

Preparing equipment for the party proceeding to the interior and making arrangements for the formation of the depot camp; the party to consist of myself, Mr. H. Gregory, Dr. Mueller, and C. Dean, Mr. Baines remaining at the depot in charge. Selected eleven of the strongest horses and had them re-shod; fitted four with riding and seven with pack saddles. The following provisions were packed for the journey: 150 pounds pork, 300 pounds flour, 50 pounds rice, 10 pounds sago, 8 pounds tea, 6 pounds coffee, 48 pounds sugar.

30th January.

Left the camp at 7.30 a.m. and steered an average course south-south-east till 10.20, over stony ground, at the junction of the sandstone and trap formation, and camped at a fine running creek which came from a rocky gorge in the sandstone range to the west of our course. Messrs. Baines and Bowman, who had accompanied us thus far, returned to the camp, which I had instructed him to move to this creek as better for the horses, as one of them had shown symptoms of poison, and I feared to leave them in that locality. A severe attack of the fever, from which I had been suffering since the beginning of the month, precluded our proceeding farther this day, as I had at first intended. At 5 p.m. it commenced raining, and continued till midnight with incessant thunder and lightning.

31st January.

Being able to mount my horse, at 8 a.m. left the camp and steered a course south-east by south, along the foot of the sandstone range--the basalt plain extending to the north-east. At 12.45 p.m. camped on a shallow watercourse trending to the south-south-west. The whole of the country to the east of our track, except some isolated hills, appear to be covered with excellent grass. The evening was raining, with continuous thunder.

1st February.

Steered north 160 degrees east from 6.25 a.m. till 7.0 across the basaltic plain, then crossed a large creek trending east, in which there were some large pools of water. We then entered the sandstone country, and crossed several rocky ridges; at 9.10 we had a good view from one of the ridges to the north and east. Fine grassy plains extended almost to the horizon, to the south the country consisted of sandstone ranges, and to the south-east large grassy plains and rocky ridges appeared to alternate with each other. Changing the course to south-east, traversed a fine plain covered with grass, beyond which was a rocky ridge, and then a second plain, in which we halted at 11.10, as I was unable to keep on my horse, owing to an attack of fever. At 2 p.m. again proceeded, and after crossing some rugged country with deep rocky ravines, at length reached a large creek, at which we encamped, though there was nothing but reeds and triodia for the horses to eat.

2nd February.

Left the camp at 6 a.m. and followed the creek up for three-quarters of an hour before we could find a crossing place; the course was then south-south-east over very broken sandstone country; at 9.50 halted in a grassy valley to feed the horses, and at 2.30 p.m. resumed our route south-east, crossed a sandstone ridge, and descended into a wide valley, the centre of which was occupied by a basaltic plain, at the edge of which we encamped at 3.55 p.m.

CRESTED PIGEON.

3rd February.

At 6.0 a.m. ascended the trap plain and steered north 190 degrees east; at 6.45 a.m. came to a large creek from the west, which joined the Victoria three-quarters of a mile to the east; but the deep and rocky character of the valley, or rather ravine, in which it ran precluded our approaching it, and we had to turn to the west, and descend from the basalt to the sandstone before the creek could be passed. Continuing an average south course, at 10.10 a.m. came to the Victoria River; the whole channel did not exceed 150 yards in breadth, of which only twenty to fifty were now occupied by water, and the rest by dry rocks and gravel, overgrown by bushes. With great difficulty we followed the river upwards, and were compelled to follow up a tributary creek for about a mile, and then encamped. Near this camp I saw the crested pigeon of Western Australia for the first time in this part of Australia.

Latitude by Leonis 17 degrees 41 minutes.

4th February.

Left the camp at 5.55 a.m. and steered nearly south for six hours, and then encamped on the bank of the Victoria River, at the end of a fine deep pool seventy yards wide, but at the lower end the water was contracted into a shallow rapid ten yards wide. The country traversed is of basaltic formation in the valley, but the hills are of sandstone, and rise on each side from 200 to 300 feet, and the whole appearance of the country shows that there has been little change in the form of the surface since the basalt was poured into the valley. On the banks of a small creek we saw a flock of tribonyx--a bird which has created some speculation as to its proper habitat, as it often makes its appearance in large numbers at the Swan River, on the western coast.

Latitude by Canopus 17 degrees 52 minutes 19 seconds.

THUNDERSTORM AND SQUALL.

5th February.

Started at 5.55 a.m., and steered south-west, keeping parallel to the river at about a mile from it, as the creeks cut so deeply into the rock near the river that they are impassable; at 9.20 a.m. crossed to the right bank of the river, and continued a south-west course, but found the country exceedingly rough and rocky, and therefore turned to the north-west to the river, and at 11.30 a.m. camped at a fine pool of water. In the afternoon we were visited by a sudden thunder-squall; fortunately the tents had not been set up, or they must have been blown to pieces. The valley of the river has contracted to about fifteen miles, and turns to the west, but a branch seems to come from the south, and a second from the north-west. The country is, however, nearly level, and it is difficult to ascertain the limits of the valley, as many portions of the original tableland exist as detached hills and ridges. Though the horses are well shod, they are becoming lame and footsore from continually travelling over rough and stony country, as more than half of the last 100 miles has been so completely covered with fragments of rock that the soil, if any exists, has been wholly concealed.

6th February.

Leaving the camp at 6.20 a.m., steered south up the valley of a large creek. At first the ground was very rough and rocky, but as we proceeded it became more level and sandy--the bed of the creek being worn in the basalt, and the hills of sandstone conglomerate rising 100 to 200 feet. Except on the bank of the creek, there was no grass, the hills being covered with triodia. Encamped in a grassy flat at 11.30 a.m.

Latitude by Pollux 18 degrees 48 seconds.

CROSS WATERSHED TO INTERIOR. HOOKER'S CREEK.

7th February.

At 6.30 resumed our journey to the south-south-west, and reached the head of the creek at 8.0 a.m. Ascending the tableland by an abrupt slope of 100 feet, our course was south one mile, when the southern slope was reached, and a large shallow valley extended across our course, beyond which a vast and slightly undulating plain extended to the horizon with scarcely a rising ground to relieve its extreme monotony. Descending by a very gentle slope into the valley, at 9.40 a.m. crossed a small watercourse trending south-east, and then passed through a plain densely covered with kangaroo-grass seven to nine feet high, and at 10.40 a.m. encountered the level sandy country beyond, which was covered with triodia and small acacia and gum trees, or rather bushes. Seeing little prospects of either water or grass to the southward, turned east to the creek, at which we encamped at 12.30 p.m. The bed of the creek was dry, except a few shallow pools of rainwater, and there had been so little rain this season that no water had flowed down the channel. A level grassy flat extended nearly a mile on each side of the creek, which indicated the extent of occasional inundations, beyond which the country was very sandy and covered with small gum-trees, acacia, and triodia.

Latitude by Pollux 18 degrees 3 seconds.

8th February.

The country to the south being so level and barren that we could not expect to find either water or grass in that direction, at 6.0 a.m. steered north 110 degrees east along the course of the creek, which turned somewhat to the north of our track for a few miles; but at 8.0 again came on its banks. The country was very barren and sandy, with small trees of silver-leafed ironbark and triodia, except on the inundated flats of the creek, which were well grassed and thinly wooded with box-trees. The course of the creek was now nearly south-east, but the channel decreased in size, and was quite dry till 10.0 a.m., when we reached a fine pool which had been filled by a tributary gully. Here we halted and shot several ducks. At 2.45 p.m. resumed our route, and at 3.20 came to a level grassy flat, on which the channel of the creek was completely lost. Crossing the flat to the east, the country was quite level and sandy; therefore turned to the north, where there seemed to be a slight depression, and at 4.50 came to a shallow pool of rainwater, at which we encamped. Frequent showers during the night.

THE DESERT INTERIOR.

9th February.

On winding the chronometers this morning, found the chain of 2139, by Arnold, was broken. Taking advantage of the cool cloudy morning, we steered south at 6.5 a.m. to ascertain if the water of the creek, after spreading on the grassy flat, collected again and found an outlet to the southward, but found the ground rise in that direction; observed a slight hollow to the west, for which we steered, but found it terminate on the sandy plain, and the country became a perfect desert of red sand, with scattered tufts of triodia and a few bushes of eucalypti and acacia. At noon, finding it hopeless to proceed further into the desert, we turned our steps to the north-north-east, and returned to our camp of last night. In returning to the camp we ascended a slight elevation, from which there was an uninterrupted view of the desert from east to south-west. The horizon was unbroken; all appeared one slightly undulating plain, with just sufficient triodia and bushes growing on it to hide the red sand when viewed at a distance. The day was remarkably cool and cloudy; the temperature at noon 86 degrees. Though the rain at the camp had been abundant during the previous night, it had not extended more than five miles into the desert, which is more remarkable, as the clouds were moving to the south.

TURN TO THE WEST.

10th February.

As the horses required a day's rest, we remained at our camp, which enabled us to repair our saddles and perform other necessary work. Repaired the chronometer and one of the aneroid barometers, which had been broken by the motion of one of the pack-horses. As there was no practicable route to the south, and the sandstone hills to the north seemed to diminish in elevation to the east, I decided on following the northern limit of the desert to the west till some line of practicable country was found by which to penetrate the country to the south. In selecting a westerly route I was also influenced by the greater elevation of the country on the western side of the Victoria, and the fact that all the larger tributaries join from that side of the valley. It is also probable that, should the waters of the interior not be lost in the sandy desert, they will follow the southern limit of the elevated tract of sandstone which occupies north-west Australia from Roebuck Bay to the Gulf of Carpentaria, both of which points are nearly in the same latitude as our present position, from which it may be assumed that the line of greatest elevation is between the 17th and 18th parallels. None of the rivers crossed by Leichhardt are of sufficient magnitude to drain the country beyond the coast range, and therefore any streams descending from the tableland to the south will either be absorbed in the sandy desert or follow the southern limit of the sandstone and flow into the sea to the south-west of Roebuck Bay. There is, however, reason to expect that, as the interior of north-west Australia is partly within the influence of the tropical and partly the extra-tropical climates, it does not enjoy a regular rainy season; and though heavy rain doubtless falls at times, it is neither sufficiently general or regular to form rivers of sufficient magnitude to force their way through the flat sandy country to the coast.

Latitude by Capella 18 degrees 20 minutes 49 seconds.

11th February.

At 6.30 a.m. proceeded up the creek, and at 12.30 p.m. camped at a shallow pool of rainwater on the flat, the channel of the creek being dry. On the northern bank of the creek we passed a small lagoon with a great number of duck and other water-fowl on it. The afternoon was cloudy, with a fresh breeze from south-east.

Latitude by Pollux 18 degrees 15 minutes 26 seconds.

12th February.

Three of the horses having strayed some distance, we did not start till 7.0 a.m., when we steered an average course of north 300 degrees east till 11.45 a.m., when we camped at a small pool of water in the bed of the creek, which was reduced to a small gully; for the first four miles we traversed the grassy flats of the creek, after which we passed over a level sandy country producing nothing but triodia, stunted eucalypti, and acacia till we again approached the creek, where the grassy flat was nearly half a mile wide, but of inferior character.

Latitude by b Tauri 18 degrees 9 minutes 44 seconds.

13th February.

At 6.50 a.m. followed the valley of the creek to the west, passing some fine flats with high grass, but the country generally very poor and thinly wooded with white-gum and silver-leafed ironbark; at 10.40 halted at a small waterhole at the foot of a low granite ridge; at 3.0 p.m. ascended the granite hills, which rose abruptly 100 to 150 feet above the plain, and extended about five miles to the south and east; to the west the sandstone covered the granite and formed a level tableland or plain; to the north a valley trended to the west, on the northern side of which the hills appeared to be granitic. Returning to the camp, examined a deep rocky ravine and found some small pools of water which might last for nearly another month.

Latitude by Castor and Pollux 18 degrees 11 minutes 20 seconds.

PIGEONS AND SEA-GULLS.

14th February.

Leaving the camp at 6.0 a.m., steered an average course of north 300 degrees east; crossing the granite ridge, we entered a level sandy country with much scrub, which was traversed till 8.40, when we entered a wide grassy plain extending to the north-west, in which direction we steered till 2.10 p.m., when we halted at a small muddy puddle two inches deep and three yards wide. Then rode on with Mr. H. Gregory to search for a larger supply of water, and found a shallow pool about a mile distant, to which the party moved and encamped. Although this pool was not 100 yards long and six inches deep, a large flock of ducks, snipe, and small gulls, were congregated at it, several thousand pigeons of species new to us came to drink. These pigeons keep in flocks of from ten to more than a thousand, feeding on the seeds of the grass on the open plains, as they never alight on trees. They are somewhat larger than the common bronze-wing; the head is black, with a little white at the base of the beak and behind the eye; back pale brown; breast, blue; throat marked with white; wings with white tips to the feathers and a small patch of bronze; tail short, tip white; feet, dull red. The evening and night were cloudy.

WILD RICE.

15th February.

At 6.5 a.m. followed a line of small trees and bushes which grew on the lower part of the grassy plain and indicated the course of the water in the wet season, and at 9.0 came to the head of a small creek trending north-west. Water was now abundant and formed large pools, and at 11.15 camped on the right bank of the creek at a pool a quarter of a mile long and fifty yards wide. This spot seemed to be much frequented by the natives, and large quantities of mussel-shells lay around their fires. The plain traversed this morning was well grassed; the soil a stiff clay loam; this plain extended three to six miles on each side of the track, and was bounded by a low-wooded country, which, in some parts, rose nearly 100 feet above the plain. In the lower part of the plain we observed the salt-bush (atriplex) and a species of rice; but as it was only just in ear, we could not judge of the quality of the grain. In the afternoon there was a fine breeze from the east which lasted till 8.0 p.m., the sky being cloudy.

Latitude by Canopus and Pollux 17 degrees 53 minutes 50 seconds.

16th February.

At 6.25 a.m. resumed our journey down the creek, which turned first west and then south-west, and at 12.20 p.m. encamped at a small pool; on the right bank of the creek wide grassy plains extended from three to five miles back towards a low-wooded ridge, but on the left bank the scrubby country came close to the creek.

Latitude by a Orionis, Canopus and Pollux 17 degrees 59 minutes 40 seconds.

17th February (Sunday).

As the water and grass were abundant on this camp, we were not compelled to move on in search of these requisites, and were enabled to observe it as a day of rest.

18th February.

Resumed our journey at 6.30 a.m., and steered an average south-west course till 11.10, and then south till 12.25 p.m., and again camped on the creek. The country consisted of wide grassy plains on the bank of the creek, without trees and well grassed; beyond the plains, at one to six miles distance, low-wooded ridges were visible; but the general aspect of the whole was extremely level. A great number of ducks and a few geese were seen on some of the pools in the creek.

Latitude by Canopus 18 degrees 4 minutes 40 seconds.

STURT'S CREEK.

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.

20th February.

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.

STURT'S CREEK.

22nd February.

Leaving the camp at 5.40 a.m., followed the creek to the west-south-west and crossed a small gully from the south; at 11.30 a.m. camped at a fine pool of water in a small creek from the south, close to its junction with the principal creek, which we named after Captain Sturt, whose researches in Australia are too well known to need comment; the grassy plains extended from three to ten miles on each side of the creek, which has a more definite channel than higher up, there being some pools of sufficient size to retain water throughout the year; the plain is bounded on the north by sandstone hills 100 to 200 feet high, and there is also a mass of hilly country to the south, the highest point of which was named Mount Wittenoon; about noon a thunder-shower passed to the east and up the creek on which we were encamped, and though the channel was then dry between the pools, at 4.0 p.m. it was running two feet deep; the grass is much greener near this camp, and there has evidently been more rain here than in any part of the country south of Victoria yet visited; a fresh southerly breeze in the morning, thunderstorms at noon, night cloudy with heavy dew.

23rd February.

At 5.50 a.m. resumed our journey down the creek, the general course first south-west and changing to the south-south-west; the channel was gradually lost on the broad swampy flat, which was overgrown with polygonum and atriplex, etc., and had a breadth of half a mile to a mile, being depressed about ten feet below the grassy plain; the grassy plain also extended to about fifteen miles wide, the hills decrease in height, and the whole country is so level that little is to be seen but the distant horizon, scarcely in any part rising above the vast expanse of waving grass. At 10.50 a.m. camped at a shallow puddle of muddy water, just sufficient to supply the horses; I walked about a mile into the polygonum flat, but could not find any water, though the ground was soft and muddy in a few spots. Mr. H.C. Gregory, when rounding up the horses in the evening, saw eight blacks watching us; we therefore went out to communicate with them; but they hid themselves in the high bushes and grass. The night was clear, and I took a set of lunar distances, which the cloudy weather had prevented for more than a week, though I had been able to get altitudes for latitude.

EFFECT OF SEASONS ON APPEARANCE OF COUNTRY.

24th February.

At 6.0 a.m. resumed our journey down the creek, which spread into a broad swampy flat about a mile wide, and covered with atriplex, polygonum, and grass, the general trend south-west; at 7.30 crossed a large watercourse from the south-east, with a dry sandy channel, no water having flowed down it this season; at 9.0 a.m. crossed to the right bank of the creek; there were many shallow muddy channels and one with running water four yards wide and one foot deep; the largest channel was near the right bank, but, except a large shallow pool, it was dry. As we advanced the country showed effects of long-continued drought, and though the creek contained some large shallow pools, the channel was dry between, the dry soil absorbing the whole of the water which was running in the channel above; at 11.50 camped at what appeared to be the termination of the pools of water, as the channel was again lost in a perfectly level flat. Great numbers of ducks, cockatoos, cranes, and crows frequented the banks of the creek above the camp, and appeared to feed on the wild rice which was growing in considerable quantities in the moist hollows, as also a species of panicum; to the south-east of the creek there is a level box-flat which extends two to three miles back to the foot of some low sandy ridges covered with triodia and a few small eucalypti; to the north-west and west the grassy plain extended to the horizon, with scarcely even a bush to intercept the even surface of the waving grass.

25th February.

The small number of water-fowl which passed up or down the creek during the night indicated that water was not abundant below our present position, and we were therefore prepared for a dry country, in which we were not disappointed, for leaving the camp at 6.15 a.m. we traversed a level box-flat covered with long dry grass; at 9.10 a.m. again entered the usual channel of the creek, which was now a wide flat of deeply cracked mud with a great quantity of atriplex growing on it, but which had lost all the leaves from the long continuance of the dry weather. The flat was traversed by numerous small channels from one to two feet deep, but they were all perfectly dry and had not contained water for more than a year; there were, however, marks of inundations in previous years, when the country must have exhibited a very different appearance, and had it been then visited by an explorer, the account of a fine river nearly a mile wide flowing through splendid plains of high grass, could be scarcely reconciled with the facts I have to record of a mud flat deeply fissured by the scorching rays of a tropical sun, the absence of water, and even scarcity of grass. The creek now turned to the south, and we followed the shallow channels till 12.30 p.m., when we fortunately came to a small pool which had been filled by a passing thunder-shower, and here we encamped during the day; a fresh breeze at times blew from the south-east and south, and the air was exceedingly warm; thermometer 106 degrees at noon, but being very dry, was not very oppressive.

LEVEL COUNTRY.

26th February.

As the course of the creek was uncertain, we steered south at 5.45 a.m. across the atriplex plain, and at 6.35 reached the ordinary right bank of the creek, which was low and gravelly, covered with triodia and small bushes; we then passed a patch of white-gum forest, and at 8 entered a grassy plain which had been favoured by a passing shower; green grass was abundant, and even some small puddles of water still remained in the hollows of the clay soil. At 10.50 came on the creek, which had collected into a single channel and formed pools, some of which appeared to be permanent, as they contained small fish. At one of these pools we encamped at 11.10. The channel of the creek is about fifteen feet below the level of the plain, and is marked by a line of small flooded-gum trees, the atriplex flat has ceased, and the soil is a hard white clay, producing salsola and a little grass; the morning clear with a moderate easterly breeze, afternoon cloudy with a few drops of rain at night.

27th February.

Resumed our journey down the creek at 6.5 a.m., when it turned to the west and formed a fine lake-like reach 200 yards wide, with rocky banks and sandstone ridges on both sides of the creek; at 11.0 camped at the lower end of a fine reach trending south: the general character of these reaches of water is that they are very shallow and are separated by wide spans of dry channel, the water being ten feet below the running level. The country is very inferior, and the grassy flats are reduced to very narrow limits, and the hills are red sandstone, producing nothing but small trees and triodia.

Latitude by Canopus and Pollux 19 degrees 12 minutes 20 seconds.

28th February.

At 6.0 a.m. we were again in the saddle, following a creek which had an average west-south-west course, but the channel was soon lost in a wide grassy flat, with polygonum and atriplex, in this flat were some large detached pools of water, 50 to 100 yards wide and a quarter to half a mile long, although the dry season had reduced them to much narrower limits than usual, as they were now eight to ten feet below the level of the plain; at 11.45 camped at a large sheet of water, just above a remarkable ridge of sandstone rocks on the right bank of the creek. Ducks, pelicans, spoonbills, etc., were very numerous, but so wild that they could scarcely be approached within range of our guns; until the present time it has been doubtful whether the creek turned towards Cambridge Gulf, the interior, or to the coast westward of the Fitzroy, but the first point being now 220 nautic miles to the north, and the general course of Sturt's Creek south-west, such a course is not probable, and it therefore only remains to determine whether it is lost in the level plains of the interior, or finds an outlet on the north-west coast. The careful and minute surveys of the coast from the Victoria River to Roebuck Bay show that no rivers exist of such magnitude as the Sturt would attain in passing through the ranges to the coast, nor does the general abrupt character of the coast-line favour the supposition that any interior waters would find an outlet in this space. That the elevation of this part of the creek is sufficient to enable it to form a channel to the north-west coast is shown by the barometric measurement: the dividing ridge between the head of the Victoria and Hooker's Creek is about 1200 feet, at the head of Sturt's Creek 1,370 feet, and our present camp 1100 feet; thus the average fall of Sturt's Creek has been 270 feet in 180 miles, or one and a half feet per mile. Now the distance to Desault Bay (which appears the most probable outlet) is 370 miles, and allowing an increase of 500 for deviations, there would be more than two feet descent per mile, which would be sufficient for the maintenance of a channel. Should the creek turn to the south and enter the sandy desert country, the water would soon be absorbed, especially as the wet season at the upper part of the creek occurs when the dry season is prevailing in the lower part of its course. That it does lose itself in a barren sandy country is, I fear, the most probable termination of the creek, and that a level country exists for many miles on each side of our route is shown by the small number and size of the tributary watercourses.

29th February.

Leaving the camp at 5.40 a.m., traced the creek to the south-west for about three miles. It formed fine reaches of water fifty to 100 yards wide; but the channel terminated suddenly in a level flat, covered with polygonum, atriplex, and grass. In this flat we passed some large shallow pools of water; at 7.30 the creek turned to the west round the north end of a rocky sandstone hill, and was joined by a tributary gully from the north, below which point the channel was a well-defined sandy bed, with long parallel waterholes on each side, but very little water remained at this time; at 9.15 the course of the creek changed to south by west, and passed through a level flat timbered with flooded-gum trees; it was about one mile wide and well grassed, but completely dried up for want of rain. The back country was thinly wooded with white-gum, and gently rising as it receded, forming sandstone hills about 100 feet high of extremely barren appearance; at 11.45 camped at a small muddy pool which would last only for a few days. A strong breeze from the west commenced early in the day, and gradually changed to the south. Thermometer, 109 degrees in the coolest shade that could be found.

DESERT OF RED SAND.

1st March.

Our horses having strayed farther than usual in search of better grass, we were delayed till 6.20 a.m., when we steered a south by west course down the valley of the creek. Immediately below the camp the country beyond the effect of inundation changed to a nearly level plain of red sand, producing nothing but triodia and stunted bushes. The level of this desert country was only broken by low ridges of drifted sand. They were parallel and perfectly straight, with a direction nearly east and west. At 11.50 camped at a fine pool of water three to five feet deep and twenty yards wide. That we had actually entered the desert was apparent, and the increase of temperature during the past three days was easily explained; but whether this desert is part of that visited by Captain Sturt, or an isolated patch, has yet to be ascertained, and the only hope is that the creek will enable us to continue our course, as the nature of the country renders an advance quite impracticable unless by following watercourses.

Latitude by Canopus, Castor and Pollux 19 degrees 40 minutes 45 seconds.

2nd March.

Left our camp at 6.30 a.m., and steered south-west by west, which soon took us into the sandy desert on the left bank of the creek. Crossing one of the sand ridges, got a sight of a range of low sandstone hills to the south-east, the highest of which I named Mount Mueller, as the doctor had seen them the previous evening while collecting plants on one of the sandy ridges near the camp. At 10.15 again made the creek, which had scarcely any channel to mark its course; the wide clay flat bearing marks of former inundations was the only indication visible. At 12.35 p.m. camped at a small muddy pool, the grass very scanty and dry. Traces of natives are frequent. Large flights of pigeons feed on the plains on the seeds of grass. A flock of cockatoos was also seen.

Latitude by Canopus and Pollux 19 degrees 51 seconds 12 minutes.

3rd March.

At 5.30 a.m. started and followed the creek on a general course south-west. There was a very irregular channel sometimes ten yards wide and very shallow, and then expanding into pools fifty yards wide. The sandy plain encroached much on the grassy flats, and reduced the winter course of the creek to half a mile in breadth. At 8.0 the course was changed to south, and at 10.15 camped at a swamp, which was nearly dry, and covered with beautiful grass. The country differed in character from that seen yesterday, there being a few scattered white-gum trees and patches of tall acacia. Salsola and salicornia are also very abundant, and show the saline nature of the soil.
