The Country Afterwards Became A Trifle Less Scrubby, And Consisted Of Sandhills, Timbered With Casuarina, And Covered, As Usual, With Triodia.

In ten miles we passed a low bluff hill, and camped near it, without any water.

On the road we saw several quandong trees, and got some of the ripe fruit. The day was warm and sultry; but the night set in cool, if not cold. Mr. Carmichael went to the top of the low bluff, and informed me of the existence of low ridges, bounding the horizon in every direction except to the south-south-east, and that the intervening country appeared to be composed of sandhills, with casuarinas, or mulga scrubs.

In Baron von Mueller's extraordinary work on Select Extra-tropical Plants, with indications of their native countries, and some of their uses, these remarks occur: - "Acacia aneura, Ferd. v. Mueller. Arid desert - interior of extra tropic Australia. A tree never more than twenty-five feet high. The principal 'mulga' tree. Mr. S. Dixon praises it particularly as valuable for fodder of pasture animals; hence it might locally serve for ensilage. Mr. W. Johnson found in the foliage a considerable quantity of starch and gum, rendering it nutritious. Cattle and sheep browse on the twigs of this, and some allied species, even in the presence of plentiful grass; and are much sustained by such acacias in seasons of protracted drought. Dromedaries in Australia crave for the mulga as food. Wood excessively hard, dark-brown; used, preferentially, by the natives for boomerangs, sticks with which to lift edible roots, and shafts of phragmites, spears, wommerahs, nulla-nullas, and jagged spear ends. Mr. J.H. Maiden determined the percentage of mimosa tannic acid in the perfectly dry bark as 8.62." The mulga bears a small woody fruit called the mulga apple. It somewhat resembles the taste of apples, and is sweet. If crab apples, as is said, were the originals of all the present kinds, I imagine an excellent fruit might be obtained from the mulga by cultivation. As this tree is necessarily so often mentioned in my travels, the remarks of so eminent a botanist upon it cannot be otherwise than welcome.

In the direction of south-south-east Mr. Carmichael said the country appeared most open. A yellow flower, of the immortelle species, which I picked at this little bluff, was an old Darling acquaintance; the vegetation, in many respects, resembles that of the River Darling. There was no water at this bluff, and the horses wandered all over the country during the night, in mobs of twos and threes. It was midday before we got away. For several hours we kept on south-south-east, over sandhills and through casuarina timber, in unvarying monotony. At about five o'clock the little mare that had foaled yesterday gave in, and would travel no farther. We were obliged to leave her amongst the sandhills.

We continued until we had travelled forty miles from Mount Udor, but no signs of a creek or any place likely to produce or hold water had been found. The only difference in the country was that it was now more open, though the spinifex was as lively as ever.

We passed several quandong trees in full fruit, of which we ate a great quantity; they were the most palatable, and sweetest I have ever eaten. We also passed a few Currajong-trees (Brachychiton). At this point we turned nearly east. It was, however, now past sundown, too dark to go on any farther, and we had again to encamp without water, our own small supply being so limited that we could have only a third of a pint each, and we could not eat anything in consequence. The horses had to be very short-hobbled to prevent their straying, and we passed the night under the umbrage of a colossal Currajong-tree. The unfortunate horses had now been two days and nights without water, and could not feed; being so short-hobbled, they were almost in sight of the camp in the morning. From the top of a sandhill I saw that the eastern horizon was bounded by timbered ridges, and it was not very probable that the creek I was searching for could lie between us and them. Indeed, I concluded that the creek had exhausted itself, not far from where we had left it. The western horizon was now bounded by low ridges, continuous for many miles. I decided to make for our last camp on the creek, distant some five-and-twenty miles north-east. At five miles after starting, we came upon a mass of eucalypts which were not exactly gum-trees, though of that family, and I thought this might be the end of the exhausted creek channel, only the timber grew promiscuously on the tops of the sandhills, as in the lower ground between them. There was no appearance of any flow of water ever having passed by these trees, and indeed they looked more like gigantic mallee-trees than gums, only that they grew separately. They covered a space of about half a mile wide. From here I saw that some ridges were right before me, at a short distance, but where our line of march would intersect them they seemed so scrubby and stony I wished to avoid them. At one point I discerned a notch or gap. The horses were now very troublesome to drive, the poor creatures being very bad with thirst. I turned on the bearing that would take me back to the old creek, which seemed the only spot in this desolate region where water could be found, and there we had to dig to get it. At one place on the ridges before us appeared a few pine-trees (Callitris) which enliven any region they inhabit, and there is usually water in their neighbourhood. The rocks from which the pines grew were much broken; they were yet, however, five or six miles away.
