  "I 
  put 
  out 
  the 
  infected 
  bugs 
  June 
  

   24th. 
  Bugs 
  were 
  very 
  numerous, 
  the 
  corn 
  being 
  almost 
  black 
  with 
  them. 
  On 
  the 
  

   30th 
  I 
  found 
  plenty 
  of 
  dead 
  ones; 
  more 
  numerous 
  under 
  the 
  stalks. 
  Frequently 
  

   the 
  ground 
  was 
  covered; 
  there 
  were 
  a 
  few 
  live 
  bugs 
  to 
  be 
  found 
  where 
  I 
  put 
  the 
  in- 
  

   fected 
  bugs, 
  but 
  150 
  yards 
  away 
  in 
  the 
  opposite 
  side 
  of 
  the 
  field, 
  there 
  were 
  plenty 
  

   of 
  bugs 
  until 
  the 
  corn 
  dried 
  up.''

   as 
  reported 
  September 
  3d: 
  "The 
  diseased 
  chinch-bugs 
  you 
  sent 
  me 
  acted 
  like 
  a 
  

   charm. 
  When 
  I 
  had 
  put 
  out 
  the 
  first 
  bugs 
  that 
  had 
  been 
  inoculated, 
  a 
  rain 
  came 
  up 
  

   within 
  less 
  than 
  six 
  hours 
  and 
  I 
  feared 
  that 
  the 
  bugs 
  would 
  be 
  destroyed 
  or 
  washed 
  

   away 
  before 
  I 
  could 
  get 
  any 
  good 
  from 
  them; 
  but 
  in 
  a 
  few 
  days 
  the 
  bugs 
  were 
  lying 
  

   dead 
  in 
  piles. 
  We 
  followed 
  it 
  up 
  for 
  a 
  few 
  days, 
  and 
  it 
  was 
  difficult 
  to 
  get 
  well 
  or 
  

   live 
  bugs 
  to 
  inoculate. 
  I 
  consider 
  it 
  a 
  grand 
  success, 
  and 
  wish 
  only 
  that 
  every 
  

   farmer 
  would 
  use 
  them 
  next 
  season 
  to 
  destroy 
  the 
  pests." 
  Under 
  November 
  date: 
  

   " 
  We 
  must 
  have 
  saved 
  100 
  bushels 
  of 
  corn, 
  and 
  if 
  we 
  had 
  commenced 
  in 
  time 
  we 
  

   would 
  have 
  saved 
  more. 
  Oats 
  were 
  ruined 
  before 
  we 
  commenced 
  with 
  infected 
  

   bugs."

  3d; 
  experiment 
  unsuccessful, 
  as 
  reported

  22d: 
  "I 
  'planted' 
  

   the 
  infection 
  in 
  a 
  field 
  of 
  corn, 
  but 
  the 
  influx 
  of 
  fresh 
  bugs 
  from 
  the 
  adjacent

  was 
  so 
  great 
  that 
  the

  could 
  not 
  be 
  a 
  fair 
  one. 
  Of 
  a 
  few 
  left 
  from 
  the 
  first 
  

   exposure 
  I 
  inoculated 
  a 
  second 
  crop,

  them

   tinued

  These 
  I

  watched 
  closely,

  "We 
  placed 
  a 
  portion 
  of 
  the 
  infected 
  bugs 
  in 
  a 
  field 
  of 
  winter 
  wheat 
  about 
  

   three

  There 
  were

  many

  on 
  this 
  field, 
  

   though 
  I 
  have 
  seen 
  them 
  more 
  numerous. 
  The

  of

  there 
  were

  Infection

   26th; 
  experiment 
  successful, 
  as 
  reported 
  October 
  18th: 
  "I 
  had 
  a 
  piece 
  of 
  winter 
  

   wheat 
  that 
  was 
  full 
  of 
  young 
  bugs, 
  and 
  the 
  3d 
  of 
  July 
  I 
  scattered 
  the 
  diseased 
  bugs 
  

   through 
  the 
  field. 
  At 
  the 
  end 
  of 
  eight 
  days 
  I 
  examined 
  the 
  field, 
  but 
  coald 
  not 
  find 
  

   any 
  dead 
  bugs. 
  I 
  looked 
  again 
  in 
  three 
  or 
  four 
  days, 
  but 
  did 
  not 
  find 
  any 
  dead 
  bugs, 
  

   and 
  then 
  I 
  thought 
  it 
  was 
  a 
  failure. 
  It 
  was 
  about 
  three 
  weeks 
  after 
  I 
  put 
  the 
  bugs 
  

   in 
  that 
  I 
  cut 
  my 
  wheat, 
  and 
  there 
  was 
  not 
  a 
  dead 
  bug 
  to 
  be 
  found. 
  I 
  had 
  a 
  piece 
  of 
  

   corn 
  by 
  the 
  side 
  of 
  the 
  wheat, 
  and 
  as 
  soon 
  as 
  I 
  cut 
  the 
  wheat 
  the 
  bugs 
  went 
  into 
  the 
  

   corn. 
  One 
  thing 
  that 
  I 
  noticed 
  was, 
  that 
  the 
  bugs 
  did 
  not 
  appear 
  to 
  be 
  as 
  lively 
  in 
  

   their 
  movements 
  as 
  they 
  were 
  the 
  year 
  before. 
  My 
  neighbors 
  had

  piece 
  of 
  barley
