﻿100 
  CONTAGIOUS 
  DISEASES 
  OF 
  THE 
  CHINCH- 
  BUG. 
  

  

  bugs 
  in 
  one 
  field 
  that 
  I 
  am 
  not 
  sure 
  has 
  been 
  infected. 
  I 
  have 
  heard 
  of 
  others, 
  but 
  

   have 
  been 
  too 
  busy 
  to 
  visit 
  them." 
  July 
  27th: 
  "Since 
  July 
  18th, 
  the 
  date 
  of 
  my 
  last 
  

   letter, 
  I 
  have 
  traveled 
  over 
  the 
  greater 
  part 
  of 
  the 
  eastern 
  half 
  of 
  this 
  county. 
  I 
  

   have 
  examined 
  50 
  fields, 
  and 
  found 
  dead 
  bugs 
  in 
  every 
  one. 
  I 
  have 
  talked 
  to 
  about 
  

   100 
  farmers, 
  and 
  received 
  reports 
  from 
  them 
  covering 
  the 
  townships 
  of 
  Chapman, 
  

   Denham, 
  Ottawa, 
  Richland, 
  Grant, 
  Sherman, 
  and 
  Blaine. 
  In 
  every 
  instance 
  the 
  bugs 
  

   are 
  reported 
  as 
  dying. 
  In 
  your 
  letter 
  of 
  July 
  21st 
  you 
  say: 
  'If 
  you 
  find 
  fields 
  in 
  

   your 
  vicinity 
  which 
  have 
  not 
  been 
  infected, 
  and 
  in 
  which 
  the 
  bugs 
  are 
  dying, 
  you 
  

   should 
  find 
  out 
  how 
  far 
  away 
  the 
  nearest 
  infected 
  fields 
  lie.' 
  It 
  would 
  be 
  a 
  big 
  job 
  

   to 
  comply 
  with 
  the 
  above 
  and 
  be 
  accurate; 
  however, 
  I 
  suppose 
  an 
  estimate 
  will 
  an- 
  

   swer 
  all 
  practical 
  purposes. 
  I 
  think 
  there 
  can 
  be 
  no 
  question 
  as 
  to 
  the 
  truth 
  of 
  the 
  

   statement 
  that 
  the 
  bugs 
  are 
  dying 
  in 
  the 
  above-described 
  territory 
  with 
  a 
  fungus 
  

   disease. 
  I 
  think 
  it 
  is 
  safe 
  to 
  say 
  that 
  the 
  disease 
  has 
  been 
  communicated 
  to 
  the 
  

   bugs 
  in 
  every 
  field 
  in 
  the 
  above 
  territory, 
  whether 
  artificially 
  infected 
  or 
  not. 
  I 
  

   think 
  it 
  safe 
  to 
  say 
  that 
  there 
  is 
  no 
  field 
  in 
  this 
  territory 
  a 
  greater 
  distance 
  than 
  two 
  

   miles 
  from 
  a 
  field 
  artificially 
  infected 
  from 
  your 
  laboratory." 
  Under 
  later 
  date: 
  "In 
  

   my 
  own 
  field 
  the 
  infection 
  saved 
  for 
  me 
  65 
  bushels 
  of 
  wheat, 
  200 
  bushels 
  of 
  corn, 
  

   and 
  $50 
  worth 
  of 
  other 
  crops." 
  Remark: 
  Note 
  that 
  the 
  very 
  wet 
  weather 
  of 
  May 
  

   did 
  not 
  destroy 
  the 
  bugs.

  " 
  A 
  short 
  time 
  be- 
  

   fore 
  harvesting 
  my 
  wheat 
  I 
  noticed 
  chinch-bugs 
  quite 
  numerous, 
  and 
  as 
  I 
  had 
  millet 
  

   adjoining 
  the 
  wheat 
  field, 
  I 
  concluded 
  that 
  if 
  the 
  bugs 
  were 
  not 
  exterminated 
  the 
  

   millet 
  would 
  be. 
  I 
  then 
  procured 
  the 
  infection 
  from 
  Mr. 
  E. 
  T. 
  Frowe, 
  but 
  before 
  

   the 
  first 
  lot 
  were 
  infected 
  the 
  bugs 
  became 
  so 
  thick 
  that 
  a 
  handful 
  could 
  be 
  scraped 
  

   from 
  a 
  surface 
  of 
  a 
  few 
  inches 
  square, 
  and 
  on 
  the 
  side 
  of 
  the 
  millet 
  adjoining 
  the 
  

   wheat 
  the 
  bugs 
  had 
  penetrated 
  about 
  10 
  feet. 
  I 
  here 
  scattered 
  the 
  infected 
  bugs, 
  and 
  

   in 
  10 
  days 
  the 
  bugs 
  disappeared 
  and 
  my 
  millet 
  was 
  saved."

   successful,

  reported 
  October 
  28th: 
  "I 
  must 
  say 
  it 
  did 
  good 
  work 
  for 
  me, 
  and 
  

   think 
  it 
  saved 
  my 
  crop 
  of 
  corn. 
  I 
  placed 
  the 
  bugs 
  in 
  five 
  or 
  six 
  places,

  in 
  

   about 
  eight 
  days 
  the

  all 
  disappeared.

  Reported 
  in 
  November: 
  "I 
  think 
  I 
  can 
  safely 
  say

   experiment 
  successful, 
  as 
  reported 
  October 
  24th: 
  "When 
  I 
  began 
  cutting 
  wheat 
  I 
  

   found 
  the 
  old 
  bugs 
  had 
  disappeared, 
  but 
  the 
  young 
  ones 
  were 
  hatching 
  out 
  rapidly, 
  

   and 
  I 
  fully 
  expected 
  they 
  would 
  destroy 
  my 
  corn, 
  which 
  had 
  wheat 
  on 
  two 
  sides 
  of 
  it. 
  

   but 
  they 
  did 
  it 
  no 
  perceptible 
  injury 
  whatever, 
  and 
  yet 
  there 
  are 
  a 
  few 
  bugs 
  in 
  my 
  

   corn. 
  A 
  neighbor 
  of 
  mine, 
  Dr. 
  A. 
  H. 
  Brill, 
  had 
  a 
  piece 
  of 
  millet 
  that 
  the 
  bugs 
  were 
  

   destroying, 
  and 
  I 
  had 
  him 
  take 
  my 
  bug 
  jar, 
  and 
  operate 
  on 
  it 
  as 
  an 
  experiment 
  to 
  

   further 
  test 
  the 
  matter. 
  I 
  asked 
  him 
  one 
  day 
  what 
  effect 
  it 
  had 
  on 
  his 
  bugs, 
  and 
  his 
  

   reply 
  was, 
  'If 
  I 
  were 
  to 
  testify 
  I 
  should 
  testify 
  that 
  it 
  killed 
  the 
  bugs. 
  1 
  They 
  were 
  

   very 
  bad 
  in 
  his 
  millet, 
  and 
  they 
  did 
  but 
  little 
  damage 
  after 
  the 
  disease 
  began 
  to 
  work."
