  attacked 
  by

  and 
  8-35 
  per 
  cent, 
  

   by

  In 
  October

   plots 
  from 
  which 
  the 
  bolls 
  were 
  taken 
  after 
  the 
  first 
  of 
  August 
  was 
  so 
  

   small 
  that 
  no 
  very 
  great 
  importance 
  is 
  attached 
  to 
  figures 
  after 
  that 
  date. 
  

   The 
  great 
  point 
  of 
  interest 
  is 
  the 
  rise 
  in 
  percentage 
  attacked 
  by

   or 
  fahia.

  buds 
  from 
  this 
  crop 
  were 
  examined 
  between

  Of 
  these 
  1-9

  were 
  attacked 
  by

  remainder 
  by
