196 THE YELLOW FEVEH CAMPAIGNS 



Finally, as the result of my investigation of the 

 numerical strength of the breeding places of the 

 stegomyia, I found the rate was not high, varying from 

 4 to 10 per cent.^ But this percentage must be 

 reduced to zero. In the Appendix will be found 

 collected together those health clauses of the various 

 Colonies which I visited which deal with anti-yellow 

 fever and antimalarial warfare ; they are useful as a 

 guide to other Colonies which may not have yet come 

 into line. These measures, and the numerous penalties 

 which followed their systematic enforcement, constitute 

 the most eloquent testimony which we possess of the 

 earnestness of this great health campaign in the West 

 Indian Colonies. 



Thus in Trinidad there have been 29 prosecutions 

 from JNIarch to April of 1909 ; 98 in St. Lucia from 

 1907-9 ; 99 in Barbados during April and iNlay of 

 1909 ; and the fines have ranged from 1-s*. to 40,s'. 



Screening ordinances and antimosquito operations 

 have been vigorously pushed on in Antigua, British 

 Honduras, and INIartinique. 



DENGUE OR DANDY FEVER 



This is a tropical fever of wide distribution, occur- 

 ring in the West Indies, Syria, tlie Far East, India, 

 Australasia, Central and South America. In tlie 



' III a letter whicli 1 have received as I go to press from Dr. Hudson of 

 Barbados, there is the jifratifyiii^ statement that '' 'l"he first fortnightly 

 returns of mos(|uito destruction in the pai'isiies shows tliat only 0"45 per 

 cent, of tlie liouscs insjiected were found to he harbouring larva-. " This is 

 a remarkably good result.
