Table VI is based on absences due to all causes as 

 recorded in the ordinary school register, while Table 

 VII is based on actual count of absences due to malaria 

 alone, including cases -over five days. Two years are 

 used for comparison, namely 1909, during which no 

 malaria campaign was in progress, and 1910, during 

 which year a crusade was carried on. It should be 

 borne in mind that the control measures did not begin 

 until March 1st, 1910, and the Anopheles mosquitoes 

 were abundant during the latter part of February and 

 early March, i.e. these were insects that had been in 

 hibernation from the previous summer. This accounts 

 for the fact that malaria was as prevalent during March 

 and April, 1910, as in the same months of the previous 

 year.
