  CONTAGIOUS 
  DISEASES 
  OF 
  THE 
  CHINCH-BUG. 
  

  

  were 
  abundant; 
  but 
  weather 
  continued 
  very 
  dry 
  and 
  sun 
  was 
  shining 
  all 
  day 
  long 
  

   and 
  I 
  could 
  not 
  see 
  any 
  dead 
  bugs 
  in 
  field. 
  Wheat 
  was 
  cut 
  July 
  29th. 
  Close 
  to 
  

   wheat 
  plat 
  I 
  had 
  some 
  new 
  plowed 
  land 
  which 
  was 
  planted 
  to 
  beans 
  and 
  a 
  row 
  of 
  

   corn; 
  bugs 
  gathered 
  on 
  it; 
  so 
  I 
  let 
  some 
  of 
  those 
  bugs 
  which 
  I 
  kept 
  in 
  the 
  jar 
  

   amongst 
  them. 
  After 
  about 
  six 
  days 
  there 
  were 
  many 
  dead 
  ones 
  sticking 
  to 
  leaves 
  

   of 
  beans 
  and 
  corn, 
  enveloped 
  in 
  white 
  fungus. 
  I 
  could 
  not 
  find 
  any 
  bugs 
  dead 
  in 
  

   neighboring 
  fields. 
  I 
  can 
  say 
  that 
  some 
  chinch-bugs 
  died 
  on 
  account 
  of 
  white 
  

   fungus 
  when 
  weather 
  was 
  wet, 
  but 
  when 
  dry 
  weather 
  set 
  in 
  fungus 
  had 
  no 
  effect."

   June 
  12th: 
  "The 
  ground 
  is 
  full 
  of 
  bugs." 
  Infection 
  sent 
  June 
  23d; 
  experiment 
  

   successful, 
  as 
  reported 
  October 
  26th: 
  " 
  The 
  experiment 
  was 
  very 
  favorable. 
  In 
  

   about 
  12 
  days 
  the 
  bugs 
  began 
  to 
  gather 
  in 
  bunches 
  and 
  die 
  in 
  the 
  field. 
  I 
  put 
  them 
  

   on 
  barley 
  and 
  all 
  of 
  them 
  were 
  killed. 
  Then 
  I 
  put 
  them 
  all 
  over 
  the 
  farm, 
  and 
  

   nearly 
  all 
  of 
  the 
  bugs 
  were 
  killed. 
  No 
  bugs 
  died 
  in 
  my 
  neighbors' 
  fields." 
  Under 
  

   date 
  of 
  November 
  13th, 
  reported 
  as 
  follows: 
  " 
  The 
  bugs 
  went 
  so 
  hard 
  at 
  the 
  barley 
  

   that 
  I 
  thought 
  they 
  would 
  kill 
  it, 
  but 
  then 
  I 
  got 
  the 
  infected 
  bugs 
  and 
  the 
  bugs 
  died. 
  

   I 
  got 
  225 
  bushels 
  of 
  nice 
  barley. 
  Of 
  oats 
  I 
  claim 
  200 
  bushels 
  more 
  by 
  my 
  use 
  of 
  

   the 
  infection, 
  and 
  of 
  rye 
  about 
  50 
  bushels 
  more. 
  The 
  bugs 
  did 
  hardly 
  any 
  damage 
  

   for 
  they 
  nearly 
  all 
  died 
  before 
  they 
  commenced 
  to 
  go 
  into 
  the 
  corn, 
  otherwise 
  they 
  

   would 
  have 
  spoiled 
  10 
  acres 
  of 
  corn."

   June 
  22d; 
  experiment 
  unsuccessful, 
  as 
  reported 
  October 
  31st: 
  "Am 
  sorry 
  to 
  say 
  

   that 
  although 
  I 
  gave 
  the 
  bugs 
  a 
  thorough 
  test 
  according 
  to 
  directions, 
  and 
  after- 
  

   wards 
  considerably 
  lengthened 
  the 
  period 
  of 
  exposure, 
  I 
  did 
  not 
  find 
  a 
  single 
  in- 
  

   stance 
  in 
  which 
  the 
  infection 
  seemed 
  to 
  work, 
  even 
  in 
  the 
  nursery."

  Infection 
  sent 
  

   July 
  17th; 
  experiment 
  doubtful 
  — 
  obscured 
  by 
  disease 
  apparently 
  already 
  present: 
  

   " 
  When 
  I 
  put 
  the 
  bugs 
  in 
  the 
  field 
  I 
  found 
  a 
  large 
  number 
  of 
  dead 
  bugs, 
  and 
  they 
  

   remained 
  in 
  bunches; 
  and 
  after 
  that 
  time 
  I 
  found 
  a 
  large 
  number 
  of 
  dead 
  bugs, 
  but 
  

   I 
  do 
  not 
  know 
  whether 
  they 
  died 
  from 
  your 
  infected 
  bugs 
  or 
  from 
  disease 
  already 
  

   among 
  them."

  field, 
  I 
  failed 
  to 
  discover 
  any 
  signs

  were 
  very

  Station, 
  Starkville, 
  Oktibbeha 
  county, 
  Mississippi. 
  Infection 
  sent 
  May 
  12th 
  

   and 
  June 
  6th; 
  experiment 
  successful, 
  as 
  reported 
  October 
  2d: 
  "In 
  the 
  latter 
  part 
  of 
  

   May 
  chinch-bugs 
  were 
  reported 
  in 
  large 
  numbers, 
  from 
  Myersville, 
  this 
  State. 
  The 
  

   first 
  lot 
  of 
  bugs 
  received 
  from 
  you 
  were 
  sent 
  to 
  the 
  locality, 
  with 
  instructions. 
  I 
  

   went 
  myself 
  to 
  the 
  locality 
  with 
  the 
  second 
  lot 
  of 
  bugs. 
  Stayed 
  a 
  few 
  days, 
  spread 
  

   the 
  disease 
  in 
  two 
  fields, 
  and 
  left 
  a 
  man 
  to 
  report 
  the 
  condition 
  of 
  these 
  and 
  other 
  

   fields 
  12 
  days 
  afterward. 
  His 
  report 
  was: 
  'The 
  corn 
  crops 
  recently 
  infested 
  with 
  

   chinch-bugs 
  are 
  doing 
  fine. 
  The 
  prospects 
  are 
  for 
  an 
  average 
  yield, 
  and 
  the 
  bugs 
  

   have 
  disappeared.' 
  ( 
  July 
  14th.) 
  When 
  at 
  Myersville, 
  however, 
  I 
  found 
  the 
  bugs 
  were 
  

   not 
  nearly 
  as 
  numerous 
  as 
  they 
  had 
  been, 
  and 
  I 
  was 
  unable 
  to 
  find 
  but 
  comparatively 
  

   few; 
  and 
  as 
  the 
  rains 
  followed 
  the 
  introduction 
  of 
  the 
  diseased 
  bugs, 
  the 
  experiment, 
  

   although 
  favorable, 
  is 
  far 
  from 
  conclusive."

  later 
  date:
