[footnote] *This chapter I owe to Mr. Henry Landor.
Accordingly, Mr. Lefroy and myself started on the expedition, on horseback, taking with us a native boy, and a pack-horse loaded with flour, tea, and sugar, and other necessaries. It will be sufficient to state that we pursued a south-east course, crossing the Hotham, the Williams, and the Arthur rivers, and traversing an indifferent country, but in many places fit for sheep-grazing, before we came to the lake, or sea, of which we were in search. When we arrived at it, we were disappointed to find it not more than six miles long, although the natives, with their usual amount of exaggeration, had increased it to an illimitable ocean. Before descending from the high land to the plain in which the lakes are situated, we caught a distant glimpse of what appeared to be a grand and broad river, pursuing a winding course through a magnificently wooded valley, with its clear bright waters dwindling in the distance to a silvery thread. A nearer examination, however, dispelled the illusion, and the beautiful river turned out to be nothing more than a chain of shallow lakes, situated in a woody valley; and only in very wet seasons flowing from one to another.
We determined to follow the chain of lakes eastward, so long as our provisions should last, or as long as our horses could find food for themselves. We proceeded east for six days, passing numberless lakes, and observing that the chain divided, one branch of lakes running north-east, and the other due east. We followed the latter until we came to a lake called Dambeling, by far the largest we had seen, being about fifteen miles long by seven or eight wide, with a good sheep country on its northern bank, and a river, which we called the Lefroy, falling into its eastern end. The river was about thirty yards wide, with a clayey bed, and large fresh-water pools, and flowed from the east, through the worst country we had seen, it being an apparently endless desert, and level to the horizon. We went one day's journey into this inhospitable country, but the want of food for our horses, and our own unprepared state, prevented us from penetrating farther. On our return, we went for two or three days north, on the outskirts of the desert, before we turned westward on our way back to York.
The only land we crossed in this expedition was situated on the head of the Hotham and Williams. The area of this country is undoubtedly very great, but its average character is below the York district, although it is well adapted for sheep-grazing.
But the most interesting feature is the barren and desolate country to the east of Lake Dambeling, doubtless a continuation of the same sterile country seen by Mr. Roe, the surveyor-General, east of York many years previously; and probably from Mr. Eyre's observation, extending quite down to the southern coast. We had no means of ascertaining the width of this dreary country, but we did not think it could be impassably wide because the river Lefroy appeared to come across it. This river, in a geographical point of view, may be important, as the character of its bed, without trees, more water-worn than the other rivers of the colony, its size, and the direction from which it comes, render it exceedingly interesting to determine how it is supplied. The sandy nature of the country on its banks, and for many miles east, and the flatness of the country, preclude the idea that it receives its supply of water from the immediately surrounding district. It must either be supplied by a country of a far better character to the eastward, or it is the outlet of another and larger lake far in the interior. From the natives we could learn nothing but that there were no kangaroos, no opossums, and no water to the east; but as their knowledge never extends 100 miles, and they would tell any lie to avoid going where they had no inclination to go, their opinions are worthless. It might be worth the while of the colony to send forth another expedition to determine the boundaries of this desolate country, as it is not improbable that a practicable rout might be discovered to South Australia by means of the river and lakes.
The outlet of the lakes is into the river Beaufort, and possibly also into the Gordon. There is no doubt that in exceedingly wet seasons the whole valley is one continuous stream, when all the lakes would be united and present a truly magnificent appearance; but as the area of evaporation is so large, and the banks of many of the lakes are high, the quantity of rain must be enormous before the valley becomes filled with a running river. Lake Barbering, where the valley divides, has a steep shore, with three distinct marks of former water-levels. All the lakes have two or more shores, showing either a decrease of rain or an elevation of the land itself, probably both. Between the present and ancient shores there is a belt of swamp-oaks and tea-trees, which show that some length of time has elapsed since the water left its old levels.
The water to fill these large reservoirs must come down the river Lefroy, as the neighbouring country is too sandy to supply it in sufficient quantities.
No question in geography has presented a wider field for conjecture than the much-debated one of the nature of the interior of Australia. Is it desert, or water, or pasture? inhabited, or destitute alike of animal and vegetable life? The explorations of Captain Sturt, and the journey of Mr. Eyre, would incline us to believe that the country is one vast sterile waste; but the journey of the latter is worth nothing as an attempt to expose the nature of the interior, since he never left the coast. It certainly shows how much suffering the human frame can endure; and whilst, as illustrative of Australian geography, it is valueless, it is highly creditable to the energies of the traveller.
The expedition of Captain Sturt has shown that to the north of South Australia the country is chiefly desert, totally incapable of supporting animal life: while the geological specimens of that traveller prove that the rich mineral strata of South Australia extend far beyond the pastoral boundaries of the colony. A reference to the journey of Mr. Lefroy and myself, from York to the south-east, will show that there exists a low level country running far beyond our farthest eastern point, which may afford abundance of water and pasture for any future expedition proceeding in that direction.
An expedition starting from these lakes in the BEGINNING OF WINTER, so as to take advantage of the first supplies of water, might advance far enough into the interior to discover at least the possibility of proceeding before the succeeding summer would render it impossible to return; for the lakes alone would not be sufficient to ensure a supply of good drinkable water during the summer, as they generally become quite salt long before summer is over. It would be necessary to find a good deep water-hole for the party to remain at during the dry season, and from which they could push out small lateral expeditions as a sort of foundation for the next season's main advance. Expeditions in Australia require great circumspection. It is not the most rapid traveller who will get the farthest, but the most prudent and cautious. I consider it quite possible to get across the island, either to South Australia or to Port Essington. Most probably it would be easier to get to the latter than the former.
