Part 54

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.
