  My 
  neighbors 
  who 
  did 
  not 
  use 
  the 
  infection 
  have 
  bugs 
  by 
  the 
  millions 
  in 
  

   their 
  broom 
  corn. 
  I 
  believe 
  we 
  could 
  exterminate 
  the 
  bugs 
  if 
  the 
  farmers 
  would 
  all 
  

   use 
  the 
  infection."

  experiment

  December 
  19th: 
  "At 
  the 
  time 
  of 
  the 
  second 
  

   experiment 
  the 
  bugs 
  had 
  gone 
  out 
  of 
  my 
  wheat 
  field 
  on 
  the 
  west 
  about 
  two 
  rods 
  

   into 
  my 
  corn, 
  also 
  into 
  my 
  neighbor's 
  corn 
  on 
  the 
  east, 
  and 
  had 
  destroyed 
  entirely 
  

   about 
  three 
  acres 
  of 
  broom 
  corn 
  on 
  the 
  south. 
  The 
  bugs 
  were 
  in 
  such 
  quantities 
  

   that 
  it 
  did 
  seem 
  that 
  there 
  were 
  enough 
  bugs 
  to 
  destroy 
  all 
  the 
  vegetation 
  in 
  the 
  

   country. 
  Six 
  or 
  eight 
  days 
  after 
  the 
  distribution 
  of 
  diseased 
  bugs, 
  they 
  lay 
  dor- 
  

   mant 
  for 
  several 
  days 
  following. 
  On 
  close 
  examination 
  they 
  all 
  had 
  disappeared, 
  

   not 
  even 
  dead 
  bugs 
  could 
  be 
  found. 
  During 
  the 
  months 
  of 
  September 
  and 
  Octo- 
  

   ber 
  I 
  was 
  around 
  all 
  over 
  the 
  country 
  buying 
  broom 
  corn, 
  and 
  I 
  took 
  particular 
  

   notice 
  of 
  chinch-bugs, 
  and 
  found 
  on 
  the 
  machinery 
  that 
  was 
  used 
  in 
  cutting 
  broom 
  

   corn 
  fodder, 
  whenever 
  your 
  remedy 
  was 
  not 
  used 
  it 
  was 
  covered 
  with 
  live 
  bugs. 
  

   Where 
  the 
  remedy 
  was 
  used, 
  could 
  see 
  no 
  signs 
  of 
  bugs."

  a

   I 
  tried

  about 
  six 
  weeks,

  it 
  did 
  its 
  work 
  well.

  " 
  The 
  trial 
  

   of 
  the 
  infected 
  bugs 
  proved 
  satisfactory. 
  Although 
  it 
  was 
  too 
  late 
  to 
  save 
  all 
  the 
  

   crop, 
  I 
  noticed 
  that 
  during 
  the 
  second 
  week 
  after 
  the 
  introduction 
  of 
  the 
  infected 
  

   bugs 
  the 
  chinch-bugs 
  in 
  the 
  field 
  disappeared 
  entirely. 
  I 
  introduced 
  some 
  bugs 
  into 
  

   a 
  small 
  patch 
  of 
  corn 
  which 
  ,Jthe 
  chinch-bugs 
  had 
  just 
  entered 
  from 
  a 
  neighboring 
  

   field 
  of 
  millet. 
  The 
  corn 
  stalks 
  were 
  fairly 
  covered 
  with 
  bugs. 
  In 
  about 
  eight 
  or 
  

   nine 
  days 
  the 
  bugs 
  began 
  to 
  disappear. 
  At 
  first 
  I 
  could 
  not 
  tell 
  what 
  became 
  of 
  

   them, 
  but 
  soon 
  noticed 
  that 
  the 
  dead 
  bugs 
  were 
  inclosed 
  in 
  a 
  whitish, 
  mouldy 
  sub- 
  

   stance."

  report, 
  of

  "The 
  miilet 
  crop 
  saved, 
  or 
  which 
  at 
  least 
  

   seems 
  to 
  have 
  been 
  saved, 
  by 
  the 
  introduction 
  of 
  the 
  infected 
  bugs,

  value 
  at 
  $100."
