Larvicidal work continued to diminish during November as the mosquito breeding season came to an end in all except the most southerly states. At the end of the month only 35 areas required regular treatment. Emphasis has shifted to drainage work and by the end of November, 22 major projects were in operation in as many war areas. In addition, minor drainage work continued in most of the areas where larviciding had stopped and no major drainage work had yet begun. The total number of employees on the MCWA program decreased by about 100 and the payroll was some $8,000 less than during October.
