Altogether, the outline of this extraordinary feature, as thus observed and traced, could not have extended over a circuit of less than 400 miles.
It is singular enough that all the springs found near the termination of Flinders range should have been salt, and that these were very nearly in the same latitude in which Captain Sturt had found brine springs in the bed of the Darling in 1829, although our two positions were so far separated in longitude.

My furthest position to the north-west was also in about the same latitude, as the most inland point gained by any previous exploring party, viz.

that of Sir Thomas Mitchell's in 1832, about the parallel of 149 degrees E.longitude; but by my being about 600 miles more to the westward, I was consequently much nearer to the centre of New Holland.

It is, to say the least, remarkable that from both our positions, so far apart as they are, the country should present the same low and sterile aspect to the west and north-west.

Since my return from the expedition, a party has been sent out under Captain Frome, the Surveyor-General, in South Australia, to examine the south-east extremity of Lake Torrens; the following is the report made by that officer upon his return.
"The most northern point at which I found water last year, was near the top of a deep ravine of the Black Rock Hills, in lat.
