work at Havana and New Orleans, the* work carried on by the 

 Superior Board of Health in Mexico, particularly in Vera 

 Cruz, the work of the Japanese Army, the anti-malarial cam- 

 paign of the French Government in Algeria, the local efforts of 

 the British in India, or the work of the Italian Government in 

 the Roman Campagna. It is interesting to note in connection 

 with this last anti-malarial campaign that the Italian Govern- 

 ment did not try the method of reducing malaria through the 

 abolition of breeding places of mosquitoes, but used methods of 

 widespread dosing with quinine and through screening of 

 houses to fight the disease. 



To sum up, then, it would seem that the average cost of the 

 work where real thorough measures have been put in force in 

 reduce mosquitoes, the cost per capita has been certainly at least 

 $1.00 per capita per year, this being due, as stated before, chiefly 

 to the fact that work has to be carried on all through the year, 

 and the fact that the operations are carried on on a smaller 

 scale, necessitating greater costs per unit of work done. 



Contrast with the cost of anti-mosquito work in the tropics 

 the cost of work in the United States. In Baltimore, for in- 

 stance, during the past summer, where such a successful cam- 

 paign was carried on, approximately $24,000 was spent with 

 somewheres in the neighborhood of 600,000 people benefited on 

 a per capita cost of 4 cents. The distribution of costs in this 

 campaign were similar to those in the New Jersey work of the 

 County Mosquito Extermination Commissions, amounting to 17 

 per cent, for administration, 30 per cent, for inspection, 40 per 

 cent, for labor, and 13 per cent, for tools and oiling. The cam- 

 paign in Baltimore had the great advantage of having all of 

 the City Departments working in cooperation, the Street Com- 

 missioner, Mr. Larkins, utilizing all of the waste ashes of the 

 city for rilling work. 



In New York City, mosquito extermination work is done on 

 an annual budget amounting to about $18,000 per year, most of 

 the money being spent for the prosecution of the salt-marsh 

 work. 



New Jersey, however, is the only State so far where large
