  CONTAGIOUS 
  DISEASES 
  OF 
  THE 
  CHINCH-BUG. 
  

  

  that 
  the 
  bugs 
  got 
  less 
  every 
  day 
  until 
  the 
  tenth 
  day, 
  when 
  I 
  could 
  scarcely 
  find 
  a 
  bug 
  

   on 
  the 
  stalks. 
  As 
  the 
  bugs 
  were 
  not 
  more 
  than 
  half-grown, 
  it 
  seemed 
  to 
  me 
  a 
  strange 
  

   act 
  that 
  they 
  left 
  the 
  corn 
  without 
  entirely 
  killing 
  any 
  of 
  it. 
  I 
  wondered 
  what 
  be- 
  

   came 
  of 
  the 
  bugs, 
  and 
  I 
  turned 
  over 
  some 
  lumps 
  of 
  dirt, 
  and 
  out 
  flowed 
  piles 
  of 
  

   dead 
  bugs, 
  and 
  live 
  ones 
  also. 
  By 
  taking 
  close 
  notice, 
  I 
  found 
  the 
  bugs 
  had 
  not 
  left 
  

   the 
  field, 
  but 
  had 
  crawled 
  down 
  in 
  the 
  dirt 
  to 
  die. 
  Half 
  of 
  the 
  bugs 
  were 
  at 
  that 
  

   time 
  dead. 
  In 
  a 
  few 
  days 
  there 
  came 
  a 
  heavy 
  rain 
  which 
  baked 
  the 
  ground. 
  I 
  have 
  

   not 
  seen 
  a 
  bug 
  there 
  since."

  experi- 
  

   ment 
  successful, 
  as 
  reported 
  August 
  22d: 
  "The 
  weather 
  was 
  wet 
  and 
  cool 
  for 
  the 
  

   first 
  10 
  days 
  after 
  I 
  put 
  the 
  infected 
  bugs 
  in 
  the 
  field, 
  and 
  they 
  did 
  not 
  seem 
  to 
  have 
  

   much 
  effect. 
  It 
  turned 
  dry 
  from 
  that 
  on 
  till 
  now. 
  I 
  could 
  not 
  find 
  many 
  live 
  bugs 
  

   to-day. 
  The 
  bugs 
  you 
  sent 
  have 
  done 
  the 
  business. 
  The 
  bugs 
  you 
  sent 
  saved 
  sev- 
  

   eral 
  acres 
  of 
  corn 
  for 
  me. 
  When 
  I 
  put 
  them 
  in 
  the 
  field, 
  the 
  corn 
  was 
  black 
  with 
  

   bugs 
  for 
  six 
  inches 
  above 
  the 
  ground, 
  and 
  into 
  the

  6 
  to 
  10

  They 
  

   never 
  got 
  any 
  further. 
  They 
  were 
  bad 
  in 
  a 
  field 
  across 
  the 
  road 
  from 
  mine; 
  the 
  dis- 
  

   ease 
  seemed 
  to 
  strike 
  them 
  also 
  a 
  week 
  or 
  10 
  days 
  after 
  it 
  commenced 
  on

  Experiment 
  successful, 
  as 
  reported 
  November 
  16th: 
  

   "I 
  made 
  a 
  number 
  of 
  experiments 
  with 
  the 
  infected 
  bugs 
  you 
  sent 
  me 
  last 
  summer. 
  

   You 
  sent 
  me 
  at 
  different 
  times 
  15 
  boxes 
  containing 
  infected 
  bugs. 
  To 
  test 
  the 
  in- 
  

   fection, 
  200 
  bugs 
  just 
  taken 
  from 
  the 
  fields 
  were 
  placed 
  in 
  a 
  large 
  glass 
  jar, 
  covered 
  

   with 
  a 
  loosely-woven 
  cloth, 
  and 
  200 
  more 
  from 
  the 
  same 
  lot 
  were 
  placed 
  in 
  a 
  similar 
  

   jar 
  with 
  a 
  few 
  infected 
  bugs 
  received 
  from 
  you. 
  Both 
  lots 
  were 
  fed 
  alike 
  daily 
  with 
  

   green 
  plants. 
  On 
  the 
  sixth 
  day 
  the 
  infected 
  lot 
  showed 
  unmistakable 
  signs 
  of 
  dis- 
  

   ease. 
  There 
  were 
  a 
  few 
  dead 
  bugs 
  in 
  the 
  uninfected 
  lot, 
  injured, 
  perhaps, 
  in 
  cap- 
  

   ture 
  or 
  in 
  the 
  handling, 
  but 
  the 
  greater 
  number 
  were 
  lively 
  and 
  eager 
  for 
  release 
  

   from 
  prison, 
  and 
  on 
  the 
  tenth 
  day 
  they 
  were 
  released, 
  apparently 
  none 
  the 
  worse 
  for 
  

   the 
  experiment. 
  One 
  hundred 
  bugs 
  just 
  taken 
  from 
  the 
  field 
  were 
  placed 
  in 
  a 
  jar 
  

   with 
  infected 
  bugs 
  received 
  from 
  you. 
  On 
  the 
  third 
  day 
  all 
  were 
  distributed 
  in 
  a 
  

   wheat 
  field 
  which 
  was 
  infested 
  with 
  bugs. 
  On 
  the 
  eighth 
  day 
  a 
  few 
  dead 
  bugs 
  were 
  

   found 
  in 
  the 
  field, 
  but 
  no 
  living 
  bugs 
  were 
  found 
  where 
  there 
  had 
  been 
  many. 
  A 
  

   slight 
  rain 
  made 
  it 
  difficult, 
  perhaps, 
  to 
  find 
  dead 
  bugs, 
  but 
  it 
  did 
  not 
  account 
  for 
  

   the 
  disappearance 
  of 
  the 
  living 
  ones. 
  After 
  the 
  wheat 
  fields 
  ripened, 
  there 
  was 
  some 
  

   complaint 
  of 
  damage 
  caused 
  by 
  bugs 
  migrating 
  from 
  the 
  wheat 
  to 
  other 
  crops, 
  and 
  

   infected 
  bugs 
  were 
  given 
  to 
  distant 
  farmers, 
  who 
  promised 
  to 
  state 
  the 
  results. 
  One 
  

   had 
  no 
  success, 
  one 
  reported 
  that 
  the 
  infection 
  destroyed 
  many 
  bugs, 
  but 
  also 
  left 
  

   many 
  unharmed, 
  and 
  one 
  reported 
  complete 
  success. 
  A 
  careful 
  inspection 
  of 
  his 
  

   field 
  verified 
  the 
  fact. 
  The 
  ravages 
  of 
  the 
  insects 
  in 
  the 
  crop 
  adjoining 
  his 
  wheat 
  

   field 
  ceased 
  in 
  five 
  days 
  after 
  the 
  infection 
  had 
  been 
  scattered. 
  Myrids 
  of 
  dead 
  in- 
  

   sects 
  were 
  found 
  and 
  few 
  living 
  ones 
  were 
  seen. 
  Those 
  who 
  have 
  closely 
  observed 
  

   the 
  results 
  of 
  your 
  remedy 
  for 
  the 
  chinch-bugs 
  believe 
  that 
  an 
  efficient 
  remedy 
  has 
  

   been 
  found."

  Under 
  November 
  date 
  correspondent 
  states 
  further: 
  

   " 
  We 
  had 
  75 
  acres 
  of 
  broom 
  corn 
  and 
  the 
  bugs 
  were 
  destroying 
  it 
  rapidly. 
  We 
  

   stopped 
  them 
  with 
  the 
  diseased 
  bugs 
  and 
  only 
  lost 
  about 
  20 
  acres. 
  We 
  believe 
  we 
  

   saved 
  55 
  acres 
  of 
  corn, 
  which 
  we 
  sold 
  for 
  $ 
  1,100 
  after 
  harvesting 
  it."
