﻿70 
  CONTAGIOUS 
  DISEASES 
  OF 
  THE 
  CHINCH-BUG. 
  

  

  paces 
  east 
  of 
  above. 
  There 
  are 
  plenty 
  of 
  young 
  bugs 
  left 
  in 
  the 
  oats 
  since 
  the 
  wheat 
  

   is 
  cut. 
  I 
  consider 
  this 
  a 
  success. 
  I 
  consider 
  that 
  I 
  have 
  saved 
  my 
  crops 
  by 
  using 
  

   the 
  diseased 
  bugs 
  sent 
  by 
  you." 
  Under 
  later 
  date: 
  "I 
  saved 
  nine-tenths 
  of 
  my 
  

   wheat 
  and 
  now 
  the 
  infection 
  is 
  clearing 
  my 
  corn 
  of 
  the 
  young 
  bugs. 
  I 
  can 
  find 
  

   large 
  numbers 
  of 
  dead 
  bugs 
  wherever 
  I 
  placed 
  the 
  diseased 
  bugs 
  in 
  my 
  100 
  acres 
  

   of 
  corn." 
  In 
  December, 
  correspondent 
  reported 
  as 
  follows: 
  "The 
  infected 
  bugs 
  

   saved 
  me 
  80 
  bushels 
  of 
  wheat, 
  90 
  bushels 
  of 
  oats, 
  1,500 
  bushels 
  of 
  corn 
  and 
  seven 
  

   acres 
  of 
  millet."

   " 
  I 
  have 
  350 
  acre's 
  of 
  wheat, 
  rye, 
  oats 
  and 
  corn 
  that 
  is 
  infested 
  with 
  chinch-bugs 
  

   They 
  are 
  very 
  thick 
  on 
  the 
  ground." 
  Infection 
  sent 
  May 
  13th 
  and 
  June 
  10th; 
  ex- 
  

   periment 
  successful, 
  as 
  reported 
  December 
  8th: 
  " 
  The 
  first 
  infected 
  bugs 
  you 
  sent 
  

   me 
  I 
  placed 
  with 
  the 
  others, 
  and 
  afterwards 
  turned 
  them 
  loose 
  in 
  my 
  wheat 
  and 
  oat 
  

   fields 
  without 
  satisfactory 
  results. 
  The 
  second 
  lot 
  proved 
  satisfactory, 
  and 
  a 
  week 
  

   after 
  putting 
  them 
  in 
  my 
  field 
  I 
  found 
  many 
  dead 
  bugs, 
  and 
  in 
  two 
  weeks' 
  time 
  I 
  

   found 
  very 
  few 
  live 
  bugs, 
  and 
  my 
  crops 
  were 
  good. 
  The 
  ground 
  was 
  covered 
  with 
  

   live 
  bugs 
  before 
  infected 
  bugs 
  were 
  turned 
  loose. 
  I 
  am 
  satisfied 
  that 
  infected 
  bugs 
  

   saved 
  my 
  crops 
  from 
  great 
  damage 
  if 
  not 
  from 
  entire 
  destruction."

   "Chinch-bugs 
  are 
  making 
  their 
  appearance 
  here." 
  Infection 
  sent 
  May 
  7th 
  and 
  June 
  

   11th; 
  experiment 
  successful, 
  as 
  reported 
  August 
  8th: 
  "As 
  I 
  wrote 
  you 
  in 
  June 
  that 
  

   my 
  experiment 
  with 
  the 
  diseased 
  chinch-bugs 
  was 
  not 
  satisfactory, 
  I 
  think 
  it 
  my 
  duty 
  

   to 
  write 
  you 
  now 
  in 
  regard 
  to 
  later 
  results. 
  Since 
  the 
  rains 
  have 
  ceased 
  I 
  have 
  put 
  

   out 
  bugs 
  infected 
  with 
  both 
  diseases 
  in 
  my 
  corn, 
  which 
  adjoined 
  the 
  wheat. 
  The 
  corn 
  

   was 
  black 
  with 
  them 
  and 
  they 
  had 
  downed 
  a 
  little 
  of 
  it. 
  I 
  did 
  not 
  see 
  it 
  for 
  about 
  

   two 
  weeks. 
  Thursday 
  last, 
  I 
  found, 
  to 
  my 
  surprise, 
  nearly 
  all 
  the 
  bugs 
  dead. 
  In 
  

   stripping 
  the 
  lower 
  blades 
  from 
  the 
  stalks, 
  the 
  dead 
  bugs 
  rolled 
  out 
  and 
  generally 
  

   crumbled 
  to 
  dust. 
  I 
  am 
  fully 
  satisfied 
  that 
  your 
  theory 
  is 
  a 
  success. 
  The 
  wheat 
  was 
  

   almost 
  a 
  failure, 
  as 
  the 
  extreme 
  wet 
  weather 
  interfered 
  with 
  the 
  experiment. 
  They 
  

   then 
  went 
  on 
  corn 
  adjoining 
  and 
  we 
  feared 
  would 
  take 
  it, 
  but 
  they 
  died 
  rapidly 
  and 
  

   injured 
  but 
  a 
  few 
  rows 
  of 
  corn. 
  Saved 
  about 
  30 
  acres." 
  Remark: 
  Note 
  that 
  "ex- 
  

   treme 
  wet 
  weather" 
  did 
  not 
  destroy 
  the 
  bugs 
  or 
  prevent 
  their 
  destruction 
  of 
  the 
  

   wheat.

   Infection 
  sent

  experiment

  reported

  13th: 
  "I 
  did 
  not 
  go 
  

   to 
  see 
  the 
  effect 
  of 
  the 
  infection 
  in 
  the 
  field 
  until 
  yesterday. 
  It 
  has 
  done 
  the 
  work 
  to 
  

   perfection. 
  Although 
  there 
  are 
  some 
  live 
  bugs 
  scattered 
  in 
  the 
  wheat, 
  there 
  are 
  not 
  

   enough 
  to 
  do 
  any 
  hurt 
  to 
  the 
  crop. 
  On 
  the 
  adjoining 
  farm 
  the 
  bugs 
  are 
  taking 
  the 
  

   wheat." 
  Under 
  later 
  date: 
  "The 
  bugs 
  took 
  the 
  entire 
  field 
  of 
  wheat 
  of 
  our 
  nearest 
  

   neighbor, 
  so 
  that 
  he 
  didn't 
  cut 
  it 
  at 
  all. 
  I 
  had 
  22 
  acres 
  of 
  rye 
  alongside 
  of 
  this 
  wheat,, 
  

   but 
  I 
  think 
  the 
  infected 
  bugs 
  saved 
  the 
  rye 
  so 
  that 
  we 
  got 
  about 
  half 
  a 
  crop. 
  They 
  

   had 
  a 
  pretty 
  good 
  hold 
  on 
  the 
  rye 
  before 
  I 
  got 
  the 
  bugs."

  The

   entirely

  young

  During 
  

   the

  the

  made 
  it
