  CONTAGIOUS 
  DISEASES 
  OF 
  THE 
  CHINCH-BUG. 
  

  

  infecting 
  bugs 
  as 
  directed 
  up 
  to 
  the 
  12th 
  of 
  July. 
  Weather 
  was 
  damp 
  with 
  slight 
  

   showers. 
  Dry 
  from 
  then 
  until 
  now. 
  The 
  first 
  infected 
  bugs 
  were 
  put 
  in 
  the 
  field 
  

   on 
  the 
  8th. 
  The 
  bugs 
  seemed 
  sluggish 
  at 
  morning 
  and 
  evening, 
  and 
  in 
  the 
  middle 
  

   of 
  the 
  day 
  moved 
  briskly. 
  In 
  a 
  few 
  days 
  there 
  were 
  a 
  few 
  dead 
  ones 
  in 
  some 
  spots. 
  

   They 
  continued 
  to 
  die. 
  I 
  kept 
  infecting 
  and 
  putting 
  out 
  in 
  different 
  parts 
  of 
  the 
  

   field 
  and 
  in 
  an 
  adjoining 
  field 
  up 
  to 
  the 
  25th 
  of 
  July. 
  By 
  that 
  time 
  they 
  were 
  dying 
  

   at 
  a 
  rapid 
  rate 
  in 
  both 
  fields 
  where 
  infected 
  bugs 
  had 
  been 
  used. 
  They 
  began 
  dying 
  

   also 
  in 
  other 
  fields, 
  and 
  by 
  the 
  20th 
  of 
  August 
  there 
  were 
  few 
  live 
  bugs 
  to 
  be 
  

   found. 
  Dead 
  bugs 
  could 
  be 
  found 
  in 
  low 
  spots 
  a 
  handful 
  in 
  a 
  place. 
  I 
  think 
  the 
  

   experiment 
  was 
  very 
  favorable, 
  and 
  the 
  bugs 
  died 
  out 
  all 
  over 
  the 
  neighborhood." 
  

   Reported 
  under 
  November 
  date: 
  " 
  My 
  saving 
  by 
  using 
  the 
  infection 
  was 
  500 
  bushels 
  

   of 
  corn.'*

   tered 
  the 
  bugs 
  as 
  you 
  directed. 
  As 
  it 
  was 
  rainy 
  weather 
  I 
  thought 
  they 
  would 
  not 
  

   amount 
  to 
  anything, 
  but 
  my 
  bugs 
  soon 
  began 
  to 
  die 
  and 
  now 
  they 
  are 
  about 
  all 
  

   dead, 
  so 
  I 
  can 
  get 
  live 
  ones 
  only 
  by 
  picking 
  them 
  one 
  by 
  one. 
  They 
  seem 
  very 
  

   sluggish. 
  There 
  are 
  a 
  great 
  many 
  dead 
  ones

  I 
  used 
  the

  killed

   chinch-bugs 
  left 
  the 
  wheat 
  field

  the 
  grain 
  was 
  cut 
  and 
  commenced 
  working 
  

   on 
  30
