   June 
  15th: 
  "The 
  corn 
  next 
  to 
  the 
  wheat 
  is 
  black 
  with 
  bugs." 
  Infection 
  sent 
  June 
  

   17th; 
  experiment 
  successful, 
  as 
  reported 
  July 
  20th: 
  "It 
  has 
  been 
  nearly 
  four 
  weeks 
  

   since 
  I 
  put 
  out 
  the 
  first 
  infected 
  bugs. 
  They 
  commenced 
  dying 
  about 
  the 
  eighth 
  

   day 
  and 
  are 
  still 
  dying." 
  Under 
  later 
  date: 
  "They 
  went 
  out 
  of 
  the 
  wheat 
  into 
  two 
  

   pieces 
  of 
  corn 
  and 
  killed 
  a 
  few 
  rows 
  and 
  then 
  did 
  no 
  more 
  damage; 
  one 
  piece, 
  six 
  

   acres, 
  made 
  30 
  bushels 
  to 
  the 
  acre; 
  the 
  other, 
  10 
  acres, 
  made 
  20 
  bushels 
  to 
  the 
  acre. 
  

   It 
  was 
  extremely 
  dry 
  weather; 
  couldn't 
  say 
  just 
  how 
  much 
  they 
  injured 
  it.

   experiment

  as 
  reported 
  January 
  23d: 
  "When 
  I 
  put 
  them 
  in 
  the 
  field 
  

   the 
  weather 
  was 
  wet 
  and 
  very 
  cool 
  for 
  the 
  time 
  of 
  the 
  year. 
  I 
  marked 
  the 
  places 
  

   where 
  I 
  put 
  them, 
  and 
  watched 
  results, 
  but 
  never 
  saw 
  any 
  dead 
  bugs; 
  tried 
  it 
  second 
  

   time, 
  with 
  same 
  result. 
  I 
  then 
  put 
  some 
  live 
  bugs 
  in 
  glass 
  with 
  infected 
  bugs, 
  and 
  

   left 
  them 
  in 
  there 
  for 
  four 
  weeks, 
  and 
  they 
  were 
  still 
  alive 
  at 
  that 
  time."

  "Chinch-bugs 
  are 
  very 
  thick." 
  Infection 
  sent

  experiment 
  successful, 
  

   as 
  reported 
  December 
  23d: 
  "The 
  experiment 
  was 
  highly 
  satisfactory. 
  I 
  put 
  them 
  

   on 
  18 
  acres 
  of 
  wheat 
  that 
  chinch-bugs 
  were 
  killing; 
  also 
  had 
  it 
  sown 
  to 
  timothy, 
  and 
  

   they 
  were 
  killing 
  it. 
  They 
  soon 
  all 
  disappeared, 
  and 
  did 
  not 
  damage 
  it 
  further. 
  I 
  

   also 
  put 
  some 
  infected 
  bugs 
  on 
  corn, 
  where 
  there 
  were 
  healthy 
  bugs, 
  and 
  it 
  cleaned 
  

   them 
  all 
  out. 
  My 
  neighbors 
  had 
  lots 
  of 
  bugs 
  in 
  the 
  fall. 
  I 
  could 
  not 
  find 
  any 
  on 
  my 
  

   farm."

  H. 
  Higginbotham; 
  experiment 
  successful, 
  as 
  reported 
  December 
  15th: 
  "I 
  used 
  

   the 
  infection 
  in 
  a 
  10-acre 
  field 
  of 
  corn, 
  where 
  the 
  bugs 
  were 
  very 
  numerous. 
  I 
  do 
  

   not 
  think 
  the 
  corn 
  would 
  have 
  made 
  anything 
  if 
  I 
  had 
  not 
  used 
  the 
  infection. 
  I 
  

   obtained 
  the 
  infected 
  bugs 
  from 
  Mr. 
  Higginbotham 
  on 
  Monday, 
  and 
  placed 
  them 
  

   in 
  my 
  corn 
  the 
  same 
  evening. 
  On 
  the 
  next 
  Monday 
  evening 
  there 
  were 
  hardly 
  any 
  

   live 
  bugs 
  in 
  my 
  corn. 
  The 
  bugs 
  had 
  gone 
  under 
  the 
  clods, 
  and 
  died. 
  I 
  think 
  the 
  

   diseased 
  bugs 
  are 
  a 
  great 
  thing. 
  I 
  bottled 
  up 
  a 
  good 
  many 
  for 
  next 
  year. 
  Mr. 
  Chas. 
  

   Harris, 
  in 
  my 
  neighborhood, 
  got 
  diseased 
  bugs 
  from 
  my 
  corn 
  field, 
  and 
  he 
  says 
  that 
  

   his 
  corn 
  was 
  a 
  great 
  deal 
  better 
  where 
  he 
  used 
  the 
  infection 
  than 
  where 
  he 
  did 
  not. 
  

   I 
  saved 
  500 
  bushels 
  of 
  corn 
  by 
  using 
  the 
  infection."

  8th: 
  "The 
  chinch-bugs 
  have 
  destroyed 
  my 
  wheat, 
  and 
  are 
  now 
  filing 
  out 
  

   into 
  my 
  corn 
  and 
  waging 
  destruction 
  on 
  it." 
  Infection 
  sent 
  July 
  10th; 
  experiment 
  

   successful, 
  as 
  reported 
  August 
  5th: 
  "I 
  proceeded 
  according 
  to 
  your 
  directions. 
  I 
  

   turned 
  the 
  bugs, 
  after 
  48 
  hours, 
  into 
  the 
  field. 
  The 
  weather 
  was 
  rainy, 
  and 
  cool 
  for 
  

   the 
  time 
  of 
  year. 
  In 
  about 
  five 
  days 
  I 
  began 
  to 
  find 
  some 
  dead 
  bugs. 
  They 
  con- 
  

   tinue 
  to 
  die 
  up 
  to 
  the 
  present 
  time. 
  There 
  are 
  still 
  a 
  few 
  live 
  bugs 
  in 
  the 
  field. 
  They 
  

   were 
  on 
  the 
  move 
  when 
  I 
  distributed 
  the 
  infected 
  bugs 
  over 
  the 
  field. 
  The 
  bugs 
  

   seem 
  to 
  be 
  dying 
  in 
  adjoining 
  fields. 
  I 
  think 
  your 
  discovery 
  a 
  good 
  one."

  Daggs,

  Yates 
  township, 
  about 
  seven 
  miles 
  distant, 
  who 
  used 
  infection 
  

   from 
  the 
  above 
  farm, 
  reported 
  as 
  follows: 
  "The 
  infected 
  bugs 
  from 
  your 
  laboratory 
  

   did 
  great 
  work 
  for 
  H. 
  B. 
  Cubbage. 
  They 
  made 
  lots 
  of 
  corn 
  for 
  him."
