  The

  condition 
  of 
  the 
  chinch-bugs 
  in 
  these 
  Mahomet 
  fields, 
  

   as 
  exhibited 
  by

  and 
  experiments, 
  is 
  thus 
  summed 
  

   up 
  by 
  observer 
  Snow: 
  

  

  '•The 
  bugs 
  must 
  have 
  been 
  immensely 
  thick 
  in 
  the 
  wheat. 
  They 
  

   then 
  attacked 
  corn 
  and 
  wheat 
  adjacent, 
  doing 
  the 
  greater 
  part 
  of 
  

   their 
  damage 
  by 
  June 
  15. 
  Millions 
  of 
  them 
  died 
  and 
  are 
  now 
  (July 
  

   15) 
  to 
  be 
  found 
  sometimes 
  hardly 
  recognizable 
  and 
  broken 
  up 
  and 
  

   (covered 
  with 
  Sporotrichum. 
  Entomophthora 
  no 
  doubt 
  carried 
  away 
  

   many, 
  as 
  it 
  was 
  found

  quantity

  the
