been built upon this land bordering the sound, and are increasing each year. They 
are free from mosquitoes, so that the operation shows the economy and the benefit 
that will result by using some means for eliminating the mosquito-breeding pools. 
As to community work, we must not fail to mention the interesting 
fact that the city of Winchester, Va., is reported to have passed an ordi- 
nance requiring property holders to treat drains and stagnant pools of 
water with kerosene during the summer season. Winchester is a town 
of high elevation and has for a long time enjoyed a reputation among 
Virginians as a cool place to spend the summer. Mosquitoes, we are 
told, however, made their appearance there a few years ago, with the 
effect that summer visitors became fewer and fewer. The passing of 
the city ordinance was deemed a matter of public policy and met with 
general approval. Police measures of this kind may not be inadvis- 
able under certain circumstances. Surely in such instances as the 
Baltimore case, mentioned in previous pages, it seems entirely appro- 
priate that the board of health should be called upon to enforce kero- 
sene treatment.
