factory solution to the problem. Bubonic plague, 

 too, is a most difficult matter, and its solution 

 lies in the complete destruction of rats as a means 

 of getting rid of the great reservoir of infection 

 from which the fleas carry the disease to man.

 borne disease is a simple problem, and the pros- 

 pects of eradicating them from the world are 

 bright compared with those of any other insect- 

 borne disease. In any organised community 

 where the will exists in the administration, lice 

 can be completely exterminated with comparative 

 ease, and their reintroduction may be guarded 

 against by the examination of immigrants.
