REMEDIES AGAINST MOSQUITOES 169 



pose, the land was boug-lit, the mosquito-breeding- places 

 were practically abolished, summer residences were built, 

 and the company realized many thousands of dollars in 

 the course of two years. There are, within a hundred 

 miles of New York City, for example, hundreds of beau- 

 tifull3^ situated localities which are not utilized to their 

 full possibilities largely on account of the prevalence of 

 mosquitoes. There are many small towns which are un-

 qualifications for this purpose are perfect. 



Aside from the main questions of health and of the 

 value of land, come the other subsidiary questions of com- 

 fort, and of the unnecessary expense of screening' houses 

 with the thoroughness necessary in many localities, which, 

 Avhen considered in bulk, become important. It seems 

 then evident that it would be a positive economj" for a 

 community to spend, if necessary, even a large sum of 

 money in attempting mosquito-extermination. In ver\' 

 many cases, however, a small sum will suffice, i^rovided 

 it is administered with intelligence. 



Dr. C. Fermi, after giving an account before the Medico- 

 physical Society of the University of Sassari, March 23, 

 1900, of his efforts to free the town from mosquitoes, esti- 

 mated the expense of freeing a town of 50,000 inhabitants 

 at from $200 to $300. This sum seems extremely small, 

 even with the low price of labor over there, but in the 

 case of Sassari the mosquito-supply was local, and the 

 insects bred almost entirely in household tanks and water 

 receptacles. It is with large marsh-areas or numerous
