SIR RUBERT BOYCE THE PREVALENCE, DISTRIBUTION AND 



SekoudI, and at the same time I addressed a circular letter to Medical 

 Officers throughout the Colony asking for information under the following- 

 heads : — 



1. A return showing the number of houses and yards in which Stegomyia 



have been found. 



2. The nature and approximate number of water-holding receptacles in 



each house. 



3. Any reports or traditions of cases of Yellow Fever in the Port. 



4. The nature and extent of any anti-larval nieasures which may have 



been carried out, such as, removal of odd receptacles, screening 

 water-containers, oiling, bush-clearing, draining or fish -stocking. 



Previous to my arrival, the Senior Sanitary Officer had instituted a 

 vigorous removal of all larva-breeding receptacles from the yards, and the 

 screening of all large water-containers. He estimated that, at the com- 

 mencement of operations, in all probability every house was breeding larvae ; 

 that in other words, the Stegomyia index w^as 100 per cent. 



On my arrival I w^ent through the town with the Senior Sanitary Officer, 

 and the assistant medical officers,, and a house to house inspection yielded 

 the following results : — 



842 houses, were examined, and larvae w^ere met with in 162; yielding 

 therefore an index corresponding to 23 per cent. 



The following: are the fioures : —
