Having now brought to a close the narrative of my explorations in 1840-1, it may not be out of place to take a brief and cursory review of the whole, and to state generally what have been the results effected. In making this summary, I have no important rivers to enumerate, no fertile regions to point out for the future spread of colonization and civilization, or no noble ranges to describe from which are washed the debris that might form a rich and fertile district beneath them; on the contrary, all has been arid and barren in the extreme. Such, indeed, has been the sterile and desolate character of the wilderness I have traversed, and so great have been the difficulties thereby entailed upon me, that throughout by far the greater portion of it, I have never been able to delay a moment in my route, or to deviate in any way from the line I was pursuing, to reconnoitre or examine what may haply be beyond. Even in the latter part of my travels, when within the colony of Western Australia, and when the occasionally meeting with tracts of a better soil, or with watercourses appearing to have an outlet to the ocean, rendered the country one of much greater interest, I was quite unable, from the circumstances under which I was placed, the reduced 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 examine more satisfactorily the character of the country, or to determine whether the watercourses, some of which occasionally bore the character of rivers (though of only short course), had embouchures opening to the sea or not.
