  structions 
  with 
  the 
  infected 
  bugs, 
  and 
  can 
  say 
  it 
  is 
  a 
  success. 
  When 
  I 
  cut 
  my 
  wheat 
  

   the 
  ground 
  was 
  alive 
  with 
  chinch-bugs. 
  I 
  had 
  corn 
  in 
  the 
  next 
  field, 
  and 
  the 
  bugs 
  

   had 
  gone 
  into 
  it. 
  My 
  boys 
  wanted 
  me 
  to 
  send 
  to 
  you 
  for 
  bugs. 
  I 
  did 
  not 
  believe 
  

   in 
  it, 
  but 
  finally 
  thought 
  I 
  would 
  try 
  it. 
  The 
  first 
  experiment 
  I 
  tried 
  was 
  in 
  a 
  patch 
  

   of 
  sweet 
  corn 
  in 
  the 
  garden, 
  which 
  was 
  black 
  with 
  bugs, 
  and 
  in 
  a 
  few 
  days 
  they 
  be- 
  

   gan 
  to 
  leave 
  the 
  corn 
  and 
  hide 
  in 
  the 
  grass 
  and 
  weeds 
  and 
  under 
  clods, 
  in 
  bunches; 
  

   and 
  in 
  about 
  10 
  days 
  the 
  bugs 
  began 
  to 
  die 
  in 
  great 
  numbers, 
  and 
  in 
  15 
  days 
  there 
  

   was 
  not 
  a 
  live 
  bug 
  to 
  be 
  found 
  in 
  the 
  garden. 
  In 
  the 
  corn 
  field, 
  the 
  first 
  few 
  rows 
  

   were 
  full 
  of 
  bugs. 
  I 
  put 
  some 
  infected 
  bugs 
  along 
  the 
  rows 
  of 
  corn, 
  and 
  in 
  the 
  millet, 
  

   and 
  wherever 
  I 
  could 
  find 
  any 
  bugs. 
  In 
  less 
  than 
  20 
  days 
  I 
  could 
  not 
  find 
  any 
  live 
  

   bugs, 
  but 
  the 
  ground 
  under 
  the 
  stalk 
  would 
  be 
  covered 
  with 
  dead 
  bugs. 
  My 
  friends 
  

   claimed 
  the 
  bugs 
  would 
  have 
  died 
  without 
  the 
  infected 
  bugs, 
  but 
  other 
  years 
  when 
  

   the 
  old 
  bugs 
  died 
  there 
  were 
  always 
  one 
  or 
  two 
  crops 
  of 
  young 
  bugs, 
  and 
  I 
  took 
  par- 
  

   ticular 
  notice 
  to 
  see 
  if 
  there 
  were 
  any 
  young 
  bugs 
  in 
  the 
  corn. 
  I 
  can 
  cheerfully 
  say 
  

   that 
  it 
  is 
  a 
  success."'

  Infection 
  sent 
  July 
  4th; 
  experiments 
  successful, 
  as 
  reported 
  October 
  1st: 
  "Ex 
  

   periment 
  No. 
  1 
  was 
  conducted 
  on 
  the 
  farm 
  of 
  Mr. 
  H. 
  D. 
  Miller, 
  a 
  wealthy 
  man 
  and 
  

   large 
  farmer. 
  Infected 
  bugs 
  were 
  scattered 
  10 
  days 
  before 
  wheat 
  was 
  cut. 
  After 
  

   cutting 
  of 
  wheat 
  on 
  the 
  north, 
  bugs 
  in 
  great 
  quantities 
  came 
  into 
  the 
  corn 
  and 
  oats; 
  

   bugs 
  already 
  sick. 
  They 
  did 
  no 
  damage 
  to 
  corn 
  at 
  all, 
  but 
  killed 
  20 
  or 
  40 
  stools 
  of 
  

   oats. 
  The 
  bugs 
  gathered 
  in 
  bunches 
  and 
  died 
  rapidly, 
  in 
  great 
  numbers. 
  Other 
  

   farmers 
  came 
  in 
  and 
  gathered 
  bugs 
  to 
  infect 
  their 
  fields. 
  Ten 
  days 
  later 
  the 
  wheat 
  

   on 
  the 
  west 
  was 
  cut, 
  and 
  non-infected 
  bugs 
  came 
  into 
  oats. 
  Although 
  the 
  oats 
  were 
  

   almost 
  too 
  old 
  for 
  them 
  to 
  do 
  much 
  damage, 
  they 
  killed 
  one 
  acre, 
  or 
  one-tenth 
  of 
  the 
  

   crop. 
  Corn 
  not 
  injured. 
  Bugs 
  still 
  dying 
  in

  numbers. 
  The 
  best 
  of 
  conditions 
  

   for 
  the 
  experiment, 
  and 
  a 
  perfect 
  success. 
  Experiment 
  No. 
  2 
  was 
  conducted 
  on 
  town 
  

   lots 
  by 
  myself. 
  Bugs 
  came 
  into 
  corn 
  on 
  north 
  side 
  of 
  patch 
  after 
  the 
  wheat 
  was 
  cut. 
  

   Just 
  as 
  wheat 
  was 
  being 
  cut, 
  I 
  scattered 
  infected 
  bugs 
  along 
  the 
  side 
  of 
  patch. 
  Eight 
  

   days 
  after 
  placing 
  infected 
  bugs 
  in 
  patch 
  I 
  found 
  them 
  much 
  reduced 
  in 
  numbers, 
  

   and 
  12 
  days 
  after 
  found 
  very 
  few 
  live 
  bugs. 
  The 
  damage 
  inflicted 
  was 
  fully 
  one-sixth 
  

   of 
  the 
  crop. 
  I 
  cannot 
  find 
  many 
  dead 
  bugs, 
  probably 
  owing 
  to 
  heavy 
  rains 
  cover- 
  

   ing 
  them

  of

  31st:

  the

  and 
  much 
  of 
  it 
  in

  the 
  country 
  looks 
  

   bad." 
  Infection 
  sent 
  May 
  13th; 
  experiment 
  successful, 
  as 
  reported 
  July 
  10th: 
  "I 
  

   kept 
  putting 
  infected 
  bugs 
  in 
  my 
  field 
  by 
  installments. 
  The 
  weather 
  was 
  very 
  wet. 
  

   and 
  it 
  was 
  so 
  muddy 
  that 
  I 
  did 
  not 
  get 
  to 
  make 
  very 
  close 
  observations 
  and 
  was 
  

   rather 
  doubtful 
  as 
  to 
  the 
  result 
  of 
  the 
  experiment. 
  But 
  my 
  wheat 
  is 
  clear 
  of 
  bugs 
  

   now. 
  while 
  my 
  neighbors' 
  fields 
  are 
  full. 
  So 
  I 
  think 
  it 
  must 
  be 
  the 
  diseased 
  bugs 
  that 
  

   did 
  the 
  work." 
  Mr. 
  Hickey 
  reports, 
  July 
  24th, 
  as 
  follows: 
  "The 
  third 
  week 
  of 
  the 
  

   experiment 
  all 
  the 
  bugs 
  died 
  in 
  his 
  field 
  of 
  wheat. 
  They 
  died 
  on 
  the 
  ground. 
  No 
  

   fungus 
  was 
  seen. 
  Did 
  not 
  have 
  any 
  live 
  bugs 
  to 
  go 
  into 
  his 
  corn." 
  Remark: 
  Note 
  

   that 
  the 
  extremely 
  wet 
  weather 
  did 
  not 
  destroy 
  the 
  bugs 
  in 
  neighboring 
  fields.

  reported 
  October 
  25th: 
  "Those 
  infected 
  bugs 
  you 
  sent 
  me 
  did 
  

   exceedingly 
  well. 
  We 
  had 
  one 
  field 
  about 
  half 
  gone 
  when 
  we 
  received 
  the 
  bugs, 
  and 
  

   another 
  partly 
  taken. 
  We 
  scattered 
  the 
  bugs 
  and 
  they 
  did 
  not 
  take 
  any 
  more. 
  We 
  

   are 
  very 
  much 
  pleased."

  November
