  22d 
  of 
  Au- 
  

   gust 
  I 
  put 
  out 
  the 
  infection 
  in 
  my 
  field 
  where 
  the 
  bugs 
  were 
  thick 
  and 
  bunched 
  on 
  

   the 
  ground. 
  It 
  had 
  rained 
  all 
  night 
  of 
  the 
  21st, 
  but 
  there 
  were 
  no 
  dead 
  bugs 
  then. 
  

   I 
  shook 
  the 
  corn, 
  to 
  scatter 
  the 
  bugs; 
  they 
  were 
  thick, 
  and 
  killing 
  the 
  corn, 
  which 
  

   was 
  in 
  ear. 
  On 
  Sunday, 
  the 
  30th, 
  two 
  of 
  my 
  neighbors 
  went 
  with 
  me 
  to 
  the 
  field, 
  

   and 
  found 
  lots 
  of 
  dead 
  bugs 
  on 
  the 
  ground, 
  also 
  on 
  the 
  corn. 
  At 
  date 
  of 
  writing 
  

   bugs 
  are 
  not 
  all 
  dead 
  yet. 
  No 
  young 
  bugs 
  can 
  be 
  found 
  in 
  my 
  field 
  since 
  using 
  your 
  

   remedy; 
  in 
  other 
  fields 
  they 
  are 
  numerous."

  putting 
  out 
  the 
  

   first 
  batch 
  of

  very 
  heavy 
  rains 
  came,

  wet 
  more

  less

  two 
  

   weeks. 
  I 
  continued 
  putting 
  out 
  bugs 
  as 
  fast 
  as 
  I 
  could 
  get 
  them 
  infected. 
  The 
  

   young 
  bugs 
  were 
  hatching 
  out 
  very 
  rapidly, 
  and 
  all 
  seemed 
  perfectly 
  healthy. 
  In 
  

   about 
  two 
  weeks 
  the 
  old 
  bugs 
  died 
  off 
  of 
  their 
  own 
  accord, 
  so 
  that 
  I 
  could 
  not 
  get 
  

   any 
  to 
  infect, 
  and 
  I 
  thought 
  it 
  was 
  going 
  to 
  be 
  a 
  failure;

  about 
  the 
  25th 
  I 
  noticed 
  

   that 
  a 
  few 
  of 
  the 
  young 
  bugs 
  were 
  dying 
  in 
  spots 
  where 
  I 
  put 
  the 
  infected 
  ones."

  I 
  put 
  no 
  infection 
  on

  of 
  the 
  corn 
  being 
  light,

   there 
  were 
  live 
  bugs 
  there. 
  I 
  think 
  the

  were 
  the

  the 
  slow 
  infection, 
  

   for 
  as 
  soon 
  as 
  the 
  dry 
  weather 
  came 
  they 
  died."
