and also in New South Wales, as far as relates to any mine 
which has once been worked. 
After the geology of the mineral fields has been investigated 
by competent geological surveyors. The surveyors of mining 
fields, who are attached to the Warden’s staff, should, on each 
mining field, be able to continue the work of recording new 
discoveries and making new maps to suit the changing condi- 
tion of each mineral field. But, to do this, they would require 
to have geological knowledge, which they should have as a sine 
qua non. 
In conclusion, it is to be hoped that, before long, we shall have a 
permanent geological survey for the whole colony on a scientific 
basis. I have already pointed out that in almost every country 
in Hurope, in the United States, and in most of our leading 
colonies, such a survey already exists. Itis time that Queensland 
should recognize the importance of the discovery of its mineral 
resources, and the investigation of the geological structure of the 
colony, as a part of the policy of the State. We ought, in fact, to 
be continually taking stock of our resources. It should be part of 
the duty of such a survey to discover new mineral fields, and to 
mark out the areas which contain water-bearing rocks; in fact, 
to pay special attention to the hydro-geology of the country. 
But, if such a permanent survey is to be established, it will have 
to be on an independent footing, and not at the beck and call of 
every Minister for Mines, who may want information about some 
new mineral field. It seems to me that the establishment of such 
a geological survey, on the lines suggested, would amply repay 
the colony in the long run.
