  experiment

  as 
  reported 
  October 
  25th: 
  "The 
  bugs 
  

   were 
  put 
  out 
  as 
  per 
  printed 
  directions, 
  but 
  in 
  a 
  few 
  hours 
  after 
  the

  were 
  put 
  

   out 
  a 
  heavy 
  and 
  driving 
  rain 
  fell, 
  and 
  it 
  continued 
  to 
  rain 
  most 
  of 
  the 
  time 
  for 
  a 
  

   week 
  following. 
  There 
  was 
  no 
  noticeable 
  effect

  the 
  healthy 
  bugs 
  in 
  the 
  field." 
  

   Remark: 
  This 
  report 
  is 
  of 
  interest 
  as 
  showing 
  that 
  the 
  heavy 
  rains 
  had 
  no 
  effect 
  on 
  

   the 
  bugs 
  in 
  the

  experiment 
  successful, 
  as 
  reported 
  November 
  22d: 
  "I 
  procured 
  in- 
  

   fected 
  bugs 
  of 
  Mr. 
  Amos, 
  and 
  after 
  catching 
  and 
  inoculating 
  healthy 
  bugs, 
  I 
  turned 
  

   some 
  loose 
  in 
  the 
  millet 
  where 
  they 
  were 
  doing 
  a 
  great 
  deal 
  of 
  damage. 
  After 
  I 
  

   turned 
  three 
  or 
  four 
  lots 
  loose 
  I 
  began 
  to 
  look 
  for 
  dead 
  ones, 
  and 
  at 
  first 
  thought 
  

   there 
  were 
  none, 
  but 
  on 
  looking 
  closer 
  I 
  found 
  that 
  the 
  young 
  ones 
  were 
  dying 
  and 
  

   the 
  little 
  ants 
  were 
  eating 
  them. 
  About 
  six 
  tons 
  of 
  millet 
  was 
  saved, 
  valued 
  about 
  

   $3 
  per 
  ton."

  experiment 
  successful, 
  as 
  reported 
  November 
  29th: 
  " 
  I 
  lost 
  15 
  acres 
  of 
  

   corn 
  that 
  was 
  listed 
  on 
  ground 
  that 
  had 
  volunteer 
  wheat. 
  The 
  bugs 
  took 
  the 
  corn 
  

   clean 
  when 
  about 
  one 
  foot 
  high. 
  When 
  I 
  went 
  to 
  put 
  out 
  the 
  infection, 
  the 
  wheat 
  

   lacked 
  a 
  week 
  of 
  being 
  ripe, 
  and 
  I 
  found 
  all 
  the 
  old 
  bugs 
  were 
  dead 
  and 
  mouldy 
  

   just 
  like 
  they 
  were 
  in 
  Mr. 
  Todd's 
  field. 
  I 
  had, 
  perhaps, 
  put 
  two 
  dozen 
  old 
  mouldy 
  

   bugs 
  in 
  a 
  fruit 
  can 
  with 
  two 
  or 
  three 
  spoonfuls 
  of 
  young 
  ones, 
  and 
  kept 
  them 
  there 
  

   about 
  three 
  days. 
  I 
  let 
  them 
  loose 
  on 
  the 
  edge 
  of 
  a 
  corn 
  field 
  next 
  to 
  the 
  wheat. 
  

   The 
  bugs 
  went 
  about 
  12 
  rods 
  into 
  the 
  corn 
  and 
  took 
  about 
  one-half 
  of 
  it 
  as 
  far 
  as 
  

   they 
  went, 
  but 
  soon 
  disappeared. 
  My 
  brother 
  wondered 
  what 
  had 
  become 
  of 
  the 
  

   bugs. 
  We 
  got 
  down 
  and 
  looked 
  and 
  found 
  heaps 
  of 
  bugs 
  in 
  all 
  the 
  little 
  depres- 
  

   sions 
  in 
  the 
  ground, 
  sometimes 
  as 
  thick 
  as 
  my 
  hand, 
  all 
  dead 
  and 
  mouldy."

  Chinch-bugs

  ex- 
  

   periment

  field 
  agent 
  August 
  4th: 
  "The 
  bugs 
  died 
  after 
  

   some 
  time, 
  and 
  I 
  never 
  saw 
  what 
  became 
  of 
  them. 
  Severe 
  rains 
  prevented 
  an 
  ear- 
  

   lier 
  success. 
  Immediately 
  after 
  the 
  rains 
  the 
  bugs 
  were 
  numerous 
  and 
  in 
  a 
  thriving 
  

   condition."

  Note 
  the 
  failure 
  of 
  the 
  rains
