CONCLUDING REMARKS. 
greater interest, I was quite unable, from the cir- 
cumstances under which I was placed, the re- 
duced and worn-out state of my horses, and the 
solitary manner in which I was travelling, ever to 
deviate from my direct line of route, either to ex- 
amine more satisfactorily the character of the 
country, or to determine whether the watercourses, 
some ol which occasionally bore the character of rivers 
(though of only short course), had embouchures 
opening to the sea or not. 
In a geographical point of view, I would hope the 
result of my labours has not been either uninteresting, 
or incommensurate with the nature of the expedition 
placed under my command, and the character of 
the country I had to explore. By including in the 
summary I am now making, the journeys I under- 
took in 1839, as well as those of 1840-1 (for a con- 
siderable portion of the country then examined was 
recrossed by the Northern Expedition), it will be 
seen that I have discovered and examined a tract of 
country to the north of Adelaide, which was pre- 
viously unknown, of about 270 miles in length, 
extending between the parallels of 33° 40' and 29° 
S. latitude. In longitude, that part of my route 
which was before unknown, extends between the 
parallels of 138° E., and 1 18° 40' E., or about 1060 
miles of direct distance. These being connected 
with the previously known portions of South- 
western, South-eastern, and part of Southern Aus- 
tralia, complete the examination of the whole of the
