29 degrees 30 minutes and long.
146 degrees, N.W., and another from Mount Arden due north, they will meet a little to the northward of the tropic, and there, I will be bound to say, a fine country will be discovered.

On what data he pledges himself to the discovery of this fine country is not stated.

It may, however, be advisable to allow Mr.Sturt to realize the state of this fine country.
"This, however, is not to be done by pursuing the line of the Darling to the latitude of Moreton Bay, which would lead him not far from the eastern coast, where there is nothing of interest to be discovered, nor does it appear advisable to pursue the Darling to the point to which he and Major Mitchell have already been, for this reason.

His preparations will, no doubt, be made at Adelaide; from thence to the point in question is about 600 miles, and from this point to the fine country, a little beyond the tropic, is 700 miles, which together make a journey of 1300 miles.

Now a line directly north from Adelaide, through Mount Arden, to the point where it crosses the former in the fine country, is only 800 miles, making a saving, therefore, of 500 miles, which is of no little importance in such a country as Australia.
"But Mr.Sturt assigns reasons for supposing that a range of mountains will be found about the 29th parallel of latitude, and Mr.Eyre, whilst exploring the Lake he discovered to the northward of the Gulf of St.
Vincent, Adelaide, notices mountains to the N.E., in about the latitude of 28 degrees.
