   loth,

  "The 
  

   lot 
  I 
  received 
  in 
  May 
  did 
  not 
  work 
  as 
  they 
  should. 
  It 
  was 
  too 
  cold 
  and 
  wet. 
  I 
  put 
  

   them 
  out 
  three 
  or 
  four 
  different 
  times. 
  It 
  would 
  rain 
  every 
  time. 
  It 
  killed 
  a 
  few. 
  I 
  

   sent 
  for 
  a 
  new 
  lot. 
  After 
  I 
  harvested 
  my 
  wheat 
  the 
  bugs 
  went 
  into 
  my 
  oats 
  and 
  mil- 
  

   let. 
  They 
  killed 
  about 
  one 
  swath, 
  but 
  after 
  I 
  put 
  the 
  infected 
  bugs 
  in 
  they 
  didn't 
  kill 
  

   the 
  oats 
  or 
  millet 
  but 
  a 
  few 
  feet 
  farther. 
  When 
  I 
  cut 
  the 
  oats 
  I 
  did 
  not 
  see 
  a 
  bug 
  in 
  

   them. 
  I 
  never 
  knew 
  bugs 
  to 
  leave 
  millet 
  before, 
  and 
  am 
  almost 
  confident 
  that 
  they 
  

   were 
  killed 
  by 
  the 
  infection."

  Infection

  experiment

   as 
  reported 
  October 
  18th: 
  "The 
  bugs 
  went 
  into 
  my 
  millet 
  and 
  corn 
  until 
  it 
  was 
  

   black 
  with 
  them. 
  I 
  put 
  the 
  infected 
  bugs 
  into 
  the 
  corn 
  and 
  millet, 
  and 
  in 
  one 
  week 
  

   they 
  commenced 
  to 
  die, 
  and 
  in 
  three 
  weeks 
  there 
  was 
  not 
  a 
  living 
  bug 
  in 
  the 
  millet 
  

   or 
  corn. 
  I 
  believe 
  I 
  killed 
  one 
  bushel 
  of 
  bugs 
  and 
  saved 
  100 
  bushels 
  of 
  corn 
  and 
  

   three 
  acres 
  of 
  millet."

  "We

  could

  up 
  a 
  cupful 
  of 
  

   dead 
  bugs 
  from 
  one 
  hill 
  of 
  corn. 
  They 
  came 
  too 
  late 
  to 
  benefit 
  my 
  wheat.

  as 
  reported 
  October 
  26th: 
  "Am 
  well 
  pleased 
  with 
  experiment. 
  It 
  was 
  

   very 
  wet 
  when 
  I 
  received 
  the 
  infection. 
  There 
  were 
  some 
  dead 
  bugs 
  to 
  be 
  found 
  is 
  

   the 
  field, 
  and 
  I 
  waited 
  some 
  time 
  before 
  I 
  put 
  the 
  infected 
  ones 
  with 
  them. 
  I 
  gave 
  

   some 
  to 
  a 
  neighbor 
  of 
  mine, 
  and 
  his 
  results 
  were 
  the 
  same. 
  There 
  were 
  lots 
  of 
  bugs 
  

   to 
  be 
  found 
  in 
  some 
  cane 
  near 
  by 
  and 
  in 
  my 
  corn 
  field. 
  The 
  corn 
  was 
  black, 
  and 
  

   in 
  about 
  four 
  or 
  five 
  days 
  they 
  began 
  to 
  die, 
  and 
  now 
  you 
  cannot 
  find 
  any 
  bugs 
  to 
  

   speak 
  of; 
  while 
  in 
  a 
  field 
  about 
  80 
  rods 
  away 
  there 
  are 
  countless 
  numbers 
  of 
  them, 
  

   and 
  the 
  corn 
  is 
  down 
  in 
  places 
  from 
  them; 
  and 
  it 
  is 
  the 
  same 
  with 
  my 
  neighbor 
  — 
  

   where 
  he 
  put 
  the 
  bugs 
  there 
  are 
  none 
  to 
  be 
  found. 
  Think 
  it 
  would 
  work 
  best 
  in 
  

   dry 
  weather. 
  Symptoms 
  were: 
  After 
  about 
  36 
  hours 
  bugs 
  began 
  to 
  bunch 
  together 
  

   and 
  were 
  very 
  sluggish." 
  Under 
  later 
  date: 
  "The 
  use 
  of 
  infection 
  saved 
  me 
  about 
  

   five 
  bushels 
  of 
  corn 
  per 
  acre 
  on 
  a 
  20-acre 
  field, 
  and 
  about 
  $25 
  worth 
  of 
  other 
  crops."

   experiment 
  successful, 
  as 
  reported 
  November 
  21st: 
  "My 
  experiment 
  with 
  the 
  in- 
  

   fected 
  bugs 
  was 
  a 
  success. 
  The 
  bugs 
  had 
  left 
  the 
  wheat 
  field 
  and 
  were 
  along 
  the 
  

   edge 
  of 
  the 
  corn 
  very 
  thick 
  for 
  about 
  20 
  rows; 
  had 
  killed 
  quite 
  a 
  sight. 
  After 
  dis- 
  

   tributing 
  the 
  infected 
  bugs, 
  they 
  never 
  scattered 
  through 
  the 
  field 
  but 
  died 
  there. 
  

   After 
  mating 
  time 
  my 
  field 
  was 
  full 
  of 
  bugs 
  from 
  neighboring 
  fields. 
  I 
  believe 
  after 
  

   your 
  method 
  is 
  thoroughly 
  understood 
  by 
  farmers 
  the 
  days 
  of 
  the 
  bugs 
  are 
  num- 
  

   bered. 
  I 
  feel 
  highly 
  pleased 
  with 
  my 
  experiment." 
  Under 
  later 
  date: 
  "The 
  use 
  of 
  

   infection 
  saved 
  me 
  about 
  300 
  bushels 
  of 
  corn."

   Slaughter; 
  experiment 
  successful, 
  as 
  reported 
  November 
  25th: 
  "I 
  sowed 
  six 
  acres 
  

   of 
  wheat 
  for 
  pasture 
  in 
  the 
  fall 
  of 
  1890. 
  In 
  the 
  spring 
  of 
  1891 
  I 
  plowed 
  it 
  under 
  

   and 
  planted 
  it 
  to 
  sweet 
  corn. 
  The 
  bugs 
  had 
  taken 
  about 
  one-third 
  of 
  it 
  when 
  I 
  got 
  the 
  

   diseased 
  bugs 
  of 
  Mr. 
  Slaughter. 
  I 
  followed 
  your 
  directions, 
  and 
  turned 
  three 
  lots 
  of 
  

   sick 
  bugs 
  in 
  different 
  parts 
  of 
  the 
  field. 
  In 
  two 
  weeks 
  I 
  had 
  no 
  bugs, 
  sick 
  or 
  well. 
  

   I 
  believe 
  if 
  I 
  had 
  not 
  got 
  rid 
  of 
  the 
  bugs 
  they 
  would 
  have 
  spread 
  all 
  over 
  the 
  place.
