THE QUESTION OF COST 53 



question of fly-reduction. The report should contain 

 suggestions as to the best way in which the fly-nuisance 

 can be dealt with. If required, the necessary funds 

 should be asked for boldly. The cause is a good one. 



The question will then arise how much money, 

 if any, will be required to institute and to carry on the 

 anti-fly campaign ? It is not sufficient to start the 

 work, but it must be kept up diligently and indefinitely. 

 Fly-campaigns, like mosquito-campaigns, once started 

 must be persevered with. It is not enough merely to 

 reduce the flies in a neighbourhood, but the reduction 

 must be maintained. The cost, however, will gradually 

 diminish as the insects disappear. This has been found 

 to be the case with mosquito-campaigns. But in 

 England fly-reduction should be counted as an ordinary 

 sanitary measure, and kept up as other sanitary 

 measures are the regular inspection of dairies, cow- 

 sheds, and other dangerous establishments. Fly- 

 breeding situations should be regularly inspected and 

 as regularly dealt with as these are. Looking at fly- 

 reduction from this point of view, no extra expense 

 should be incurred, for there is already a sanitary 

 organisation in this country to deal with all insanitary 

 places ; and fly-breeding grounds are insanitary places. 



Each breeding-ground must be inspected and dealt 

 with once every seven days, and the fly-maggots 

 destroyed regularly every week. In some places this 

 regular inspection, which should continue summer and 

 winter, may cost money ; in this case a correct estimate 

 must be obtained. The estimate can be made in the 

 following manner. Make a house-to-house examina- 

 tion of the town, and note the exact spots where the 

 flies are breeding. This sounds a considerable under- 

 taking, but it was done easily at Port Said, a town of
