CONCLUDING REMARKS. 
wondered at, considering the circumstances under 
which the sketch was constructed. 
At Mount Hopeless the variation was 4° E., at 
Mount Arden it was 7° 24' E. Now if this varia- 
tion be applied proportionately to all the courses 
and bearings as marked down in the original chart, 
commencing from Mount Arden, it will be found 
that Mount Serle will be brought by my map very 
nearly in longitude to where Captain Frome places it.* 
Our latitudes appear to agree exactly. The second point 
upon which some difference appears to exist between 
Captain Frome’s report and mine is the character of 
Lake Torrens itself, which Captain Frome thought 
might more properly be called a desert. This, it 
will be observed, is with reference to its south-east 
extremity — a point I never visited, and which I only 
saw once from Mount Serle ; a point, too, which 
from the view 1 then had of it, distant although it 
was, even at that time seemed to me to be “apparently 
dry,” and is marked as such in Arrowsmith’s chart, 
published from the sketch alluded to. 
There is, however, a still greater, and more singular 
difference alluded to in Captain Frome’s report, which 
it is necessary to remark ; I mean that of the eleva- 
tion of the country. On the west side of Flinders 
range, for 200 miles that I traced the course of Lake 
Torrens, it was, as I have observed, girded in its 
* This has been done by Arrowsmith in the map which 
accompanies these volumes;— to which Mr. Arrowsmith has also 
added Captain Frome’s route from the original tracings.
