do not include the cost of major drainage work but simply the 

 expenses for inspecting and oiling. If the cost of the general 

 drainage work, what might be termed permanent improvements, 

 is added, the cost would run up very much higher than these 

 figures indicate. An average of about $5,000- each year is spent 

 in Port Said. 



During 1903 and 1904 mosquito control was made effective in 

 Honolulu, Hawaii, at an expenditure of $2,000 per annum. 

 The population numbered 50,000. The area involved was 12 

 square miles. This was an expenditure of 4 cents per capita and 

 $i66\66 per square mile per annum, but the above cost does not 

 include inspection work Avhich was furnished by the Board of 

 Health, or the laborers and teams used which were furnished 

 by the department of Public Works, also the expenses of inves- 

 tigation and of supervision which were furnished by the Ha- 

 waiian Experiment Station. The mosquitoes to be dealt with 

 in Hawaii were the domestic species. The Department of Public 

 Works cooperated in the collection and disposal of refuse non- 

 combustible material. The low cost of the work in Honolulu 

 was made possible only by the use of the local government ma- 

 chinery and by the support of local public opinion. But if the 

 other expenditures for administration, inspection and drainage 

 were added to this amount, the cost would probably be much 

 higher than the average cost of the work in similar sections in 

 New Jersey. 



Ross, in "The Prevention of Malaria," quotes an estimate for 

 the Island of Mauritius amounting to 135,0001 rupees per annum, 

 or about $50,000 for a population of 375,000, or 13 cents per 

 capita. Again, this estimate did not include the cost of the 

 drainage work, which would add at least 60 per cent, addi- 

 tional. The wages paid the laborers and inspectors, moreover, 

 were but a mere fraction of what would have to be paid for 

 similar class of labor in our own section. 



No< figures are available as to the cost of carrying on anti- 

 mosquito work in any of the other tropical or semi-tropical coun- 

 tries where more or less wide scale operations have been in 

 force. These campaigns include the yellow fever and malaria
