and this will apply to all branches of social life ; but we are not 

 advanced so far yet. We cannot therefore advocate legislative 

 proceedings with regard to frost prevention, but we must try to 

 persuade the farmer not to leave all to an uncertain hope, but to 

 watch his own interest and that of his neighbour also. 



With all the advantages of the already named system of 

 meteorological stations, and the Weather Bureau in Brisbane 

 which makes forecasting of frost so available, and by reason of 

 the geographical position of Queensland on the very edge of the 

 tropics, there is hardly any country in the world where the frost 

 phenomenon could be studied with such a success as here. Also 

 the presence in Queensland of such a distinguished meteorolo- 

 gist as Mr. C. L. Wragge is a reason for going into the study 

 of this question. 



I do not know which Society in Queensland is the- 

 proper one for taking up the practical part of this question of 

 preventing damages by frost ; but I think in addressing this body 

 of scientific workers that I have placed the question in the 

 hands of the men who are the most suitable for giving the 

 matter a scientific attention, the result of which would be bene- 

 ficial not only to this country but to the whole humanity.
