Part 58

At 5.50 steered north 10 degrees east, crossing the creek several times, and at 10.0 turned to the north-north-east and north-east, crossing the sandstone hills, round which the creek turns at a right angle, and at 12.10 p.m. camped on the creek near our track of the 29th February. Nearly all the pools of water had dried up, and the water at the camp had become brackish; some of the pools, however, must be permanent, as there were small fish in them. A great party of natives appeared to be travelling up the creek, as fresh fires are constantly seen to the north-east along its course. A cool breeze from the west to north-east moderated the heat, the temperature at 2 p.m. 103 degrees; passing clouds from the east in the afternoon.

FOLLOW UP STURT'S CREEK.

14th March.

Resumed our route and followed the creek upwards from 5.50 a.m. till 1.50 p.m., when we camped about three miles south-west of camp 45 at the first pool before the atriplex flat. A short distance above the camp we crossed a large sandy creek, which proved to be the cause of the change in the character of Sturt's Creek below that point. As our route was at a greater distance from the creek than in tracing it down, it gave a better opportunity of ascertaining the nature of the country beyond the influence of inundation; to the north-west a vast plain traversed by low ridges of gravel and drift sand, clothed with a scanty growth of triodia and a few hakea bushes, rose gradually from the creek, but on the south-east a more abrupt sandstone slope terminated in a similar plain of somewhat greater elevation, and showed that we were still within the bounds of the desert. Moderate breeze from the north-west changing to north-east; passing clouds; a slight shower at 11.0 p.m.

15th March.

Resumed our route at 5.50 a.m., steering north 40 degrees east, one hour into the triodia plain, then north 60 degrees east till 9.20 a.m., when we reached the first large pool in the creek, and rounding the bend camped at one of the narrow pools above the sandstone ridges. The water in the larger pools had sunk from six inches to a foot since we had passed downwards, and almost all the pools were now dry. The morning clear and cool, with clouds and light showers in the afternoon accompanied by thunder.

16th March.

As there was no water in the creek for the next thirty-three miles, we filled the water-bags and prepared for an early start; but unfortunately the horses had strayed farther than usual, which delayed us till 7.0 a.m., when following nearly the outward route, passed close to camp 43, the waterhole at which was dry, and at 1.0 p.m. halted under the shade of a few acacia-trees during the heat of the day, and resumed our journey at 3.0 p.m., following the south-east side of the plain through which the creek flows. The ground was stony and bad travelling, but as the moon was clear and bright we succeeded in reaching the first pool of water at 8.30 p.m.; this was one mile above Camp 42, the water at which had dried up, though four feet deep on the 24th February. The pool at which we now camped appears to be permanent; it is 100 yards wide and 300 long, the water three feet deep close to the bank. Ducks were numerous, and I shot four in the morning. An easterly breeze continued through the day, and as usual there were a few clouds towards sunset. Unfortunately, the dry weather had warped the scale of the thermometer to such an extent that it broke the tube.

DENISON PLAINS. WATER DRYING UP.

17th March.

We were again delayed by trifling circumstances, and did not leave the camp until 7.40 a.m., but having nearly cleared the desert the weather was comparatively cool. Steering an average course north-east, traversed the wide grassy plains on the right bank of Sturt's Creek, to which the name of Denison's Plains was given. At 2.0 p.m. camped at a small pool in the polygonum flat, which was all that remained of the water which had covered the flat to the extent of three-quarters of a mile in breadth, and was running when we passed down last month. Our course this day showed the great extent of the grassy plains to the north-west, as we did not see the limit at any point in that direction. Cool breeze from east with thin clouds all day.

18th March.

Left the camp at daylight and proceeded to Camp 40 on the outward route, and halted for the remainder of the day to rest the horses, as a heavy stage lay before us across the dry country. Large flocks of cockatoos came to the pool at this camp, and we shot thirty-three, which was a very welcome addition to our provisions. Strong easterly wind; passing clouds.

19th March.

Steered north 60 degrees east at 6.35 a.m., and followed up the course of the creek, crossing the right bank at 9.0, when there was nothing but the polygonum flat to mark its course; at 10.30 altered the course to nearly east, passing a large sheet of brackish water, which appeared deep and permanent at the lower end, but shallow at the upper part; at 11.20 encamped at a small pool of fresh water in a back channel, the creek being brackish, and we were anxious to procure a supply of good water before proceeding further, as the next three stages of the outward track were now destitute of water. Strong easterly breeze; light clouds.

20th March.

At 5.55 am steered 110 degrees; at 6.20 struck a small creek with steep banks; altered the course to 90 degrees, crossing two small watercourses from the north with a little water in the deeper portions of their beds, the general character of the country box flats and open grassy plains near the creek. At 7.25 entered a large grassy plain extending north and east for ten miles, and at 9.15 halted at a small watercourse which retained a little water in a grassy hollow, our object in halting thus early being to enable us to start fresh in the afternoon, and, should the country continue open, to push on through the night, by which the water could be reached before the heat of the sun was too great for travelling. At 3.5 resumed our march and traversed level grassy plains extending one to five miles on each side of our route; at 7.0 observed a native fire about two miles to the north, from which we concluded that water existed at no great distance, and at 7.15 were fortunate in finding a pool of rainwater in a slight depression of the plain, and encamped. We could not find sufficient wood near the camp to boil our tea, but were satisfied with the discovery of a sufficient supply of water.

21st March.

We were again in the saddle at 5.15 a.m., and continuing our course north 73 degrees east, reached the limit of the open plain, which turned to the south-east and extended to the horizon; at 6.40 entered the wooded country which bounded the plain, and the soil changed from a rich clay-loam to sandy and gravelly soil with fragments of sandstone, the vegetation consisting of small white-gum trees, shrubby acacia, and triodia, with a few patches of grass. The country gradually rose till 9.25, when we came to an abrupt descent into the valley of Sturt's Creek, but the country did not improve in character till 10.20, when we came to the grassy flats; at 10.50 camped at a large open pool of water in the bed of the creek. On the pools there were large flights of whistling ducks, but so wild that they could not be approached within range of our guns. Moderate breeze from east with light clouds from south-east during the day. The weather has for the past ten days been so misty that I have not been able to get a good set of lunar distances, and it is useless to observe unless under circumstances favourable for accuracy.

22nd March.

5.35 a.m. found us again travelling up the creek on a northerly course; at 7.20 changed the course north-east by north, and at 11.30 camped about a mile below Camp 35. The hill at the bend of the creek proved to be basaltic, with a stratum of ironstone conglomerate resting on it. The pools of water in the bed of the creek were much reduced and all the smaller ones dried up.

23rd March (Sunday).

The feed and water not being in sufficient quantity to permit of our resting at this camp, we followed up the creek nearly on the outward course. A few miles above the creek a party of blacks came out of the creek and commenced a distant parley, but on one of the party approaching them they picked up their spears they had secreted in the grass and ran away into the bed of the creek. After six and a half hours' journey camped at the lower end of the pool, where we had halted on the 15th February; near the northern bend of the creek we passed a fine deep pool, which appears to retain water through the dry season. All the smaller pools had dried up, and the larger ones had sunk two feet since we were here in February.

24th March.

As the horses had not had a day's rest for some time past, we remained at the camp to refresh them before attempting to cross the dry country which divides the southern waters from those flowing to the north-west coast. As the nearest water which we knew to exist was now fifty miles to the east, and the country in that direction very bad travelling, we were now, however, eighty miles in a direct line from the depot camp, and as that course would take us over new and unexplored country I determined to attempt a direct route.

1700 FEET ABOVE SEA LEVEL.

25th March.

At 6.20 a.m. steered north 40 degrees east, and, leaving Sturt's Creek, traversed open grassy plains till 9.5, when we entered a wooded country, with white-gum trees and underwood, acacia, triodia, and patches of grass; the soil a poor sandy red loam. At 11.0 passed to the south of an extensive grassy plain trending to the north-west; at 12.30 p.m. halted to ease the horses' backs from their loads, and resumed our route at 1.40, and at 2.0 crossed a ridge of stony country which the aneroid showed to be about 1700 feet above the sea level, and was the highest spot yet visited by the Expedition. At 2.20 altered the course to east, and followed a slight depression till 4.0, when we came to a dry watercourse trending north-west; this was traced down in search of water till 6.30, when we halted for the night, without finding any water. The day being very calm and hot, the horses were very much distressed for want of water; but as there was a little green grass on the bank of the creek, they were able to feed for a few hours during the night.
