CONCLUDING REMARKS. 
137 
Australia, and what may be considered as having 
been the next island, can be ascertained and crossed 
over, new and valuable regions may yet be offered 
for the extension of the pastoral interest of our 
Colonies, and for the general spread of civilization 
and improvement. 
1 have already observed that several circumstances 
connected with my own personal experience have led 
me to the conclusion, that there is no inland sea 
now occupying the centre of New Holland ; it will 
be sufficient to name three of the most important of 
these. 
First. I may mention the hot winds which in 
South Australia, or opposite the centre of the conti- 
nent, always blow from the north, to those, who have 
experienced the oppressive and scorching influence 
of these winds, which can only be compared to the 
fiery and withering blasts from a heated furnace, I 
need hardly point out that there is little probability 
that such winds can have been wafted over a large 
expanse of water. 
Secondly. I may state that between the Darling 
river and the head of the Great Australian Bight, 
I have at various points come into friendly commu- 
nication with the Aborigines inhabiting the outskirts 
of the interior, and from them I have invariably learnt 
that they know of no large body of water inland, 
fresh or salt ; that there were neither trees nor 
ranges, but that all was an arid waste so far as they 
were accustomed to travel.
