Olga they would perhaps not even be seen, but they gradually 
increase in height until the Rawlinson Range is reached. Here, 
then, is an extensive and fertile field awaiting scientific and 
systematic examination, in which much that is now a matter of 
conjecture requires to be verified. 
An expedition such as that fitted out by Mr. W. Horn, of 
South Australia, is required for the work. The party equipped 
and maintained by the above-named gentleman called for savants 
from the Universities of each of the colonies, New South Wales 
being represented by Mr. J. A. Watt, M.A., B.Sc. This party 
was most ably conducted by Mr. C. Winnecke, of Adelaide, and 
returned after its four months’ ramble in the Macdonnell, Kric- 
hauff, and Gill Ranges rich in discovery to every branch of 
science. 
An opportunity here presents itself to those upon whom fortune 
has largely smiled to shed the lustre of discovery upon their 
names by the equipment and maintenance of an expedition that 
shall have for its object scientific search in this almost unknown 
region. Such a party would leave the settlements at Gill’s 
Range or Erldunda and proceed from there to Mt. Olga, where 
the first depot would be formed pending the discovery of a 
suitable water being found further west, and nearer the scene of 
operations. No difficulty would then be experienced in reaching 
Sladen Water. It may almost be taken for granted that valuable 
waters would be found before reaching so far west. From the 
western end of the Rawlinson, the party would return by a 
slightly different route, and if time and circumstances allowed, 
before leaving Sladen Water light parties would be formed to 
visit Fort Mueller to the south, and Mt. Leisler to the north. 
Taking advantage of the winter months by being at Mt, Olga in 
April, the party would return to the settlements before the 
excessive heat of summer. 
It is with the hope that it will lead to a close examination of 
this country that these remarks are offered. The discovery of 
gold- bearing rocks in Western Australia in country that had been 
traversed by such close observers as Gregory Austin, Lefrey 
Forrest, and many others, leads me to think that somewhat 
similar conditions will prevail here, for we know that where 
Devonian slates, sandstones, and granites protrude, precious 
metals impregnate the fissures to a greater or less extent. 
The conviction is now forced upon us that no pasture lands of 
sufficient extent may be looked for that would develop the western 
interior, but we may reasonably entertain the hope that the 
mining industry in this latitude will challenge the enterprise of 
the Australian people.
