  CONTAGIOUS 
  DISEASES 
  OP 
  THE 
  CHINCH-BUG. 
  

  

  flax 
  next 
  my 
  wheat, 
  and 
  corn 
  25 
  rods 
  from 
  wheat 
  where 
  the 
  bugs 
  were 
  thickest. 
  The 
  

   bugs 
  did 
  not 
  get 
  to 
  my 
  corn. 
  I 
  think 
  65 
  or 
  70 
  per 
  cent, 
  of 
  them 
  died 
  in 
  the 
  wheat 
  

   field 
  and 
  along 
  the 
  border. 
  The 
  old 
  ones 
  died 
  first. 
  If 
  it 
  hadn't 
  been 
  for 
  the 
  in- 
  

   fection, 
  they 
  certainly 
  would 
  have 
  taken 
  the 
  corn, 
  as 
  they 
  were 
  so 
  numerous."

  experiment 
  

   successful, 
  as 
  shown 
  in 
  report 
  of 
  October 
  27th: 
  "I 
  can 
  say 
  the 
  infected 
  bugs 
  proved 
  

   a 
  success. 
  I 
  followed 
  the 
  directions 
  as 
  near 
  as 
  I 
  could. 
  There 
  were 
  lots 
  of 
  dead 
  bugs 
  

   to 
  be 
  found 
  after 
  the 
  third 
  trial, 
  and 
  the 
  bugs 
  disappeared 
  and 
  left 
  the 
  corn 
  and 
  

   sorghum, 
  and 
  I 
  haven't 
  been 
  able 
  to 
  see 
  old 
  or 
  young 
  bugs 
  since, 
  so 
  I 
  give 
  the 
  trial 
  

   the 
  credit 
  of 
  destroying 
  the 
  bugs. 
  Mr. 
  Milks 
  here 
  got 
  of 
  my 
  neighbor 
  and 
  it 
  saved 
  

   his 
  millet, 
  and 
  the 
  dead 
  bugs 
  lie 
  thick 
  on 
  the 
  ground, 
  and 
  it 
  did 
  the 
  work 
  to 
  perfec- 
  

   tion, 
  without 
  doubt. 
  I 
  think 
  it 
  saved 
  my 
  corn 
  and 
  millet, 
  and 
  part 
  of 
  my 
  sorghum; 
  

   and 
  the 
  season 
  was 
  favorable 
  to 
  the 
  chinch-bugs 
  in 
  the 
  months 
  of 
  July 
  and 
  August, 
  

   but 
  there 
  were 
  none 
  to 
  be 
  found." 
  Reported 
  under 
  November 
  date: 
  "I 
  estimate 
  my 
  

   saving 
  at 
  $100 
  worth 
  of 
  corn, 
  and 
  $30 
  worth 
  of 
  millet 
  and 
  sorghum."

  Infection 
  sent 
  June

  experiment 
  suc- 
  

   cessful, 
  as 
  reported 
  November 
  2d: 
  "I 
  turned 
  the 
  infected 
  bugs 
  into 
  my 
  wheat 
  field, 
  

   the 
  weather 
  being 
  unfavorable, 
  raining 
  all 
  the 
  time. 
  In 
  from 
  four 
  to 
  six 
  days 
  the 
  

   bugs 
  began 
  to 
  die. 
  Their 
  appearance 
  was 
  exactly 
  like 
  the 
  ones 
  you 
  sent 
  me, 
  mouldy. 
  

   I 
  kept 
  catching 
  live 
  bugs 
  and 
  distributing 
  infecteds 
  for 
  10 
  days, 
  and 
  to 
  my 
  surprise 
  

   the 
  bugs 
  were 
  all 
  gone. 
  I 
  am 
  satisfied 
  that 
  it 
  is 
  a 
  grand 
  success, 
  and 
  wish 
  to 
  con- 
  

   gratulate 
  you 
  on 
  your 
  discovery." 
  Under

  "The 
  

   chinch-bugs 
  are 
  coming 
  into 
  my 
  oats 
  and 
  corn 
  from 
  adjacent 
  fields; 
  they 
  are 
  multi- 
  

   plying 
  very 
  rapidly, 
  in 
  spite 
  of 
  the 
  wet 
  weather." 
  Infection 
  sent 
  June 
  29th; 
  experi 
  

   ments 
  uccessful, 
  as 
  reported 
  July 
  11th: 
  "I 
  placed 
  from 
  one 
  to 
  two 
  of 
  the 
  infected 
  

   bugs 
  on 
  each 
  hill 
  of 
  corn, 
  in 
  a 
  row 
  alongside 
  of 
  the 
  field 
  adjacent 
  to 
  the 
  wheat 
  field. 
  

   The 
  bugs 
  were 
  very 
  abundant 
  on 
  the 
  corn, 
  and 
  moving 
  very 
  lively 
  on 
  the 
  ground. 
  

   On 
  July 
  9th 
  I 
  made 
  an 
  examination 
  at 
  hills 
  of 
  corn 
  where 
  diseased 
  bugs 
  had 
  been 
  

   placed, 
  and 
  found 
  live 
  bugs 
  apparently 
  sick, 
  and 
  a 
  great 
  many 
  dead 
  ones. 
  At 
  some 
  

   hills, 
  nearly 
  a 
  tablespoonful 
  of 
  dead 
  bugs 
  were 
  found 
  under 
  clods 
  near 
  the 
  hills 
  

   where 
  they 
  had 
  taken 
  shelter 
  and 
  died. 
  The 
  white 
  mould, 
  characteristic 
  of 
  the 
  disease, 
  

   was 
  distinctly 
  revealed 
  by 
  the 
  microscope, 
  and 
  on 
  the 
  day 
  following 
  could 
  be 
  seen 
  

   by 
  the 
  naked 
  eye. 
  The 
  cool 
  weather, 
  retarding 
  their 
  movements, 
  has 
  prevented 
  a 
  

   rapid 
  spread 
  of 
  the 
  infection, 
  the 
  dead 
  bugs 
  found 
  being 
  confined 
  mostly 
  to 
  the 
  

   hills 
  infected. 
  A 
  few 
  warm 
  days 
  will, 
  I 
  am 
  confident, 
  complete 
  their 
  destruction." 
  

   Later 
  report 
  gives 
  further 
  evidence 
  of 
  the 
  success 
  of 
  the 
  experiment, 
  as 
  follows: 
  

   " 
  The 
  bugs 
  threatened 
  corn, 
  oats, 
  timothy, 
  and 
  millet. 
  The 
  last 
  two 
  crops 
  were 
  saved. 
  

   The 
  oats 
  were 
  badly 
  damaged 
  before 
  the 
  infection 
  was 
  introduced. 
  The 
  bugs 
  got 
  a 
  

   start 
  in 
  the 
  corn, 
  but 
  were 
  checked 
  and 
  destroyed 
  in 
  a 
  short 
  time 
  after 
  infection 
  

   was 
  applied, 
  and 
  the 
  corn 
  is 
  safe." 
  Under 
  date 
  of 
  December 
  20th: 
  "The 
  infection 
  

   saved 
  900 
  bushels 
  of 
  corn, 
  and 
  five 
  tons 
  of 
  millet."

  Applied

  aid 
  May 
  4th: 
  "The 
  

   bugs 
  are 
  doing 
  considerable 
  damage 
  in 
  this 
  vicinity." 
  Infection 
  sent 
  May 
  6th, 
  and 
  

   re-sent 
  June 
  6th; 
  experiment 
  successful, 
  as 
  reported 
  October 
  12th: 
  "The 
  infected 
  

   bugs 
  that 
  you 
  sent 
  me 
  June 
  6th 
  proved 
  a 
  success. 
  I 
  dropped 
  the 
  bugs 
  at 
  the 
  end 
  

   of 
  the 
  corn 
  and 
  wheat; 
  the 
  bugs 
  went 
  out 
  of 
  the 
  stubble 
  into 
  the 
  corn 
  and 
  covered 
  

   it 
  about 
  two 
  feet 
  up, 
  and 
  it 
  began 
  to 
  look 
  as 
  though 
  the 
  corn 
  would 
  be 
  killed 
  en- 
  

   tirely 
  by 
  them. 
  In 
  a 
  few 
  days 
  I 
  noticed 
  that 
  the 
  bugs 
  on 
  the 
  corn 
  were 
  dying, 
  and
