Journals of Australian Explorations. Francis Thomas Gregory
out shooting, but it was difficult to ascertain whether with hostile intentions. From this time to our return we regularly mounted sentry during the night, and no one was allowed to quit the party any distance alone--a precautionary measure the necessity of which was fully borne out by the sequel.
26th April.
From our camp, which was situated about eight miles west of Mount Murchison, we fairly commenced the exploration of unknown country. Following the river nearly north-north-east for fourteen miles it turned abruptly to the east; we, however, held our course, which at four miles further brought us to the foot of Mount Narryer, which we ascended, and procured a valuable round of angles from its summit. This hill has an altitude of 1,688 feet above the sea, and is formed by the eruption of a coarse dark-coloured crystalline trap through a base of amorphous sandstone, the direction of the range of which it forms a part being nearly north and south. Skirting round the north end of this range, we struck east over a stony plain, thinly grassed amongst open wattles, and at five miles again came upon the Murchison some time after dark. The pools here were somewhat larger than for many miles below, being from sixty to eighty yards wide and half a mile in length, the water in them becoming decidedly brackish; samphire, atriplex, and other salsolaceous plants being abundant on the banks.
27th April.
We only advanced nine miles, owing to Mr. Moore and Dugel having to return for one of the water-beakers, which had been torn off the pack-saddle the previous night in a thicket. Towards our bivouac, which was in latitude 26 degrees 23 minutes 38 seconds, the country near the river improved much, the channel of the river becoming very shallow; the water had spread over the flats for more than half a mile on either side, large flooded-gum trees growing abundantly with a fine sward of grass beneath, the soil being a rich brown clay loam. Gallinule and cockatoos were in large flocks feeding on the grass seeds, which were now nearly ripe.
28th April.
To latitude 28 degrees 7 minutes the river continued to come from north by east through an extensive plain, bounded on the west by a low range of trap and granite hills, at an average distance of six or seven miles, while to the eastward only a few distant peaks were visible, flooded-gum growing plentifully for more than a mile back from the river, on flats of tolerably good pasture. Receding somewhat further from the river, the country opens out into extensive plains yielding but little grass; atriplex bush and thinly scattered stunted acacia and melaleuca trees forming almost the entire vegetation.
29th April.
A few miles nearly north brought us to where a considerable tributary joins the Murchison from the north, the river trending first north-east, then east, and finally towards the afternoon it came from the southward of east, our bivouac being only seven miles north of the previous night, while we had made nearly eighteen miles of easting. The bed of the river had gradually become more rocky as we ascended, gneiss with quartz dykes passing through it and yielding a large quantity of salt, rendered the running water of the river scarcely drinkable; the only fresh water was found in the back channels filled by the late inundations. The ranges which ran parallel to the river to the westward terminated some miles to the north of the bend. Another range, apparently granitic and broken up into detached peaks, commencing a little to the eastward of its termination, runs east for about twenty miles at the distance of six or seven miles from the north bank of the river.
To the eastward an elevated range with two conspicuous summits, which were respectively named Mount Matthew and Mount Hale, terminated the view in that direction, while to the south only a few detached peaks were visible.
To-day we first observed a very beautiful convolvulus, which we afterwards found to bear roots like a sweet potato, some of them more than a pound weight and well flavoured, forming a very important article of food to the natives. The flowers are numerous, and measure from two to three inches in diameter, their outer edges of a dark lilac, deepening to a rich purple at the centre, with a pale green convolute ribbing on the outside, the stem and leaf of the plant resembling the kennedya. Mr. Drummond, to whom I have described it, considers it an important discovery, as by cultivation it might become a valuable addition to our Australian esculents.
A small species of rock-melon was also found in great abundance about the size of a pigeon's egg, somewhat bitter to the taste, but they were not ripe; in other respects it much resembles the cultivated varieties.
The bed of the river at this night's bivouac had attained an elevation of 1,240 feet above the sea.
LEAVE THE MURCHISON FOR THE GASCOYNE RIVER.
30th April.
Finding that the Murchison was leading us too much to the eastward, the object of the expedition being to reach the Gascoyne with as little delay as possible, we quitted the river on a north-north-east course for about eight miles over a tolerably grassy plain, in some parts open, with atriplex and samphire, and in others rather thickly studded with acacia and melaleuca. Ascending a granite hill of 150 feet elevation, the plain was observed to the eastward to extend to the horizon, only broken by one remarkable bold trap hill at the distance of twenty miles, which was eventually named Mount Gould, the main Murchison flowing round its southern base, while a considerable tributary from the north-east passed close under it to the north-west. To the north of our position the country rose into a succession of stony ridges thinly grassed and nearly destitute of trees; in the valleys the kangaroo grass was tolerably plentiful and quite green--a sufficient evidence that we had now arrived within the influence of the rains that had produced the recent inundation, which gave us every hope of being able to push across the country intervening between this and the Gascoyne. We accordingly altered our course to north-west for the remainder of this and the following day, crossing several tributaries to the Murchison, in which we found plenty of water, and on their banks an abundant supply of grass for our horses, the streams being generally divided from each other by low stony ridges or plains of red sandy loam, yielding a rather scanty supply of grass.
