other heavy burden on such communities due to sickness, the
consequent loss of income and the expense attendant thereto.
The remarkable results due to mosquito control and the conse-
quent increase in real estate values, health and vigor of the
peoples, etc., are so numerous that only a few may be cited-
as in Havana, Panama Canal Zone, Port Said, Singapore, et
al. Where diseases are not present, but only noxious mosquitoes,
their reduction brings about a marked increase in land values.
No finer example can be cited than the work done in New
Jersey. Dr. Headlee ( 1926)) after presenting a detailed sum-
mary of the tax valuations’ of the Atlantic and Bay Coast area
of New Jersey for the past twenty-five years, concludes with
this remarkable statement. “Thus it appears, under New Jer-
sey coastal conditions, that, where salt marsh mosquitoes are
naturally absent, there has’ occurred an average increase in tax-
able values during the last ten years of fifty-five per cent more
than where they are still present or only very recently reduced
and that, where salt marsh mosquitoes have been largely elim-
inated during the last ten years, there has occurred an average
annual increase of seventy-five per cent more than where they
are still present or very recently reduced.”
