JOPICAL AUSTRALIA FOR THE WHITE RACES. 419 



to the most dreaded tropical diseases should spread through 

 the Australian tropics, the ravages among the population 

 living under the described conditions would be simply- 

 stupendous. In my opinion two measures should be taken 

 for the amelioration of the present conditions, and as pre- 

 ventives against the imminent future dangers : — 



1. A proper medical sanitary supervision of the alien 



elements, and the greatest possible restriction of 

 their evil contact, not only with the aboriginals, but 

 also with the white population itself. 



2. Improvement of the living conditions of the white 



population within the tropical and subtropical part 

 of Australia, with special regard to the houses, food 

 and water. The Australian patriotic associations 

 would have here a vast and important field of activity 

 in spreading the knowledge of improved conditions 

 among the white element in the affected parts.
