192 THE YELLOW FEVER CAMPAIGNS 



make the house-to-house inspection with the district 

 medical officers and all the sanitary inspectors available, 

 together with the chairman and others of the Sanitary-

 animals, the drinking-water barrels, the washing-tubs, 

 and the innumerable odds and ends, are all carefully ex- 

 amined for the larvcE of the stegomyia. By this means

 places is worked out, and the efficacy of the work 

 accomplished by the medical authority in charge 

 gauged. 



AVhilst making these investigations, ample oppor- 

 tunity is afforded of talking with the householders and 

 of explaining to them the significance of the visit and 

 the necessity for the removal of all stagnant water 

 in and out of doors. An estimate is at the same time 

 made of the general cleanliness of the interior and 

 exterior of the house, and if there are any broken bottles 

 or odd tins about the yard, the householder is ad-

 purpose we are frequently accompanied by the dust 

 contractor and his carts. 



To sum up the results of my house-to-house inspec- 

 tions in the West Indies, I examined —
