An Experiment in Civic Hygiene. - - During the summer of 1913 an interesting experiment on the relation of flics and filth to disease- was carried on in New York City by the Bureau of Public Health and Hygiene of the New York Association for improving the con- dition of the poor. Two adjourning blocks were chosen in a thickly populated part of the Bronx near a number of stables which were the sources of great num- bers of flies. In one block all houses were screened, garbage pails were furnished with covers, refuse was re- moved and the sur- roundings made as sanitary as possible. In the adjoining block conditions were left unchanged. During (he summer as flies began to breed in the manure heaps near the stables all manure was disinfected. Thus the breeding of flies was checked. The cam- paign of education was continued during the summer by means of moving pictures, nurses, boy scouts, and school children who became interested. At the end of the summer it was found thai there had been a considerable decrease in the number of cases of fly-carried diseases and a still greater decrease in the total days of sickness (especially of children) in the screened and sanitary block.
