  CONTAGIOUS 
  DISEASES 
  OF 
  THE 
  CHINCH-BUG. 
  

  

  early 
  in 
  the 
  spring 
  proved 
  a 
  complete 
  success, 
  as 
  the 
  disease 
  spread 
  to 
  an 
  extent 
  to 
  

   terminate 
  the 
  damage 
  they 
  were 
  doing 
  to 
  growing 
  crops. 
  The 
  bugs 
  received 
  later, 
  

   when 
  the 
  dry 
  weather 
  set 
  in, 
  did 
  not 
  seem 
  to 
  spread 
  so 
  well. 
  The 
  disease 
  more 
  easily 
  

   spread 
  and 
  seemed 
  more 
  contagious 
  in 
  wet 
  01 
  damp 
  weather 
  than 
  in 
  dry. 
  The 
  differ- 
  

   ent 
  farmers 
  receiving 
  infection 
  through 
  me 
  were 
  generally 
  successful 
  in 
  checking 
  the 
  

   bugs. 
  Under 
  later 
  date: 
  "The 
  use 
  of 
  the 
  infection 
  saved 
  me 
  about 
  800 
  bushels 
  of 
  

   corn, 
  and 
  other 
  crops 
  amounting 
  to 
  about 
  $100."

  The

  considerably 
  damaged

  chinch-bugs.

  " 
  The 
  result 
  was 
  not 
  satisfactory 
  with 
  the 
  

   first 
  bugs 
  sent 
  me. 
  The 
  second 
  time 
  they 
  were 
  sent 
  I 
  furnished 
  some 
  to 
  J. 
  W. 
  Avers, 
  

   a 
  farmer 
  living 
  near 
  this 
  town, 
  and 
  the 
  result 
  was 
  satisfactory. 
  The 
  bugs 
  in 
  his 
  

   field 
  all 
  died 
  or 
  left 
  the 
  place, 
  while 
  in 
  adjoining 
  fields 
  they 
  were 
  thick 
  and 
  went 
  into 
  

   corn 
  adjoining 
  wheat 
  fields. 
  Later 
  in 
  the 
  season 
  and 
  after 
  wheat 
  harvest, 
  I 
  found 
  

   where 
  the 
  bugs 
  had 
  gone 
  out 
  of 
  the 
  wheat 
  field 
  into 
  a 
  field 
  of 
  corn 
  belonging 
  to 
  us, 
  

   and 
  had 
  taken 
  the 
  corn 
  for 
  about 
  50 
  rows, 
  not 
  leaving 
  a 
  stalk. 
  I 
  then 
  sent 
  to 
  you 
  

   for 
  more 
  bugs 
  and 
  scattered 
  them 
  in 
  the 
  field 
  according 
  to 
  directions. 
  In 
  about 
  10 
  

   days 
  I 
  could 
  find 
  no 
  live 
  bugs 
  whatever, 
  but 
  a 
  great 
  many 
  dead 
  ones 
  under 
  the 
  

   blades 
  of 
  corn. 
  I 
  am 
  of 
  the 
  opinion 
  that 
  there 
  is 
  great 
  benefit 
  derived 
  by 
  using 
  

   these 
  infected 
  bugs."

  The

  worked

  is, 
  the

   died. 
  I 
  would 
  find

  bugs 
  consisting 
  of 
  a 
  mass 
  of 
  legs, 
  shells 
  and 
  

   bug 
  debris. 
  These 
  were 
  mostly 
  of 
  a

  or 
  dark

  others

  a
