  Summarizing 
  the 
  results 
  of 
  these 
  experiments, 
  it 
  will 
  be 
  seen 
  that 
  

   ninety-three 
  dead 
  specimens 
  were 
  taken 
  out 
  of 
  this 
  box. 
  none 
  dead 
  

   more 
  than 
  twenty-four 
  hours 
  when 
  so 
  removed 
  and 
  transferred 
  to 
  

   moist 
  sand, 
  where 
  twelve 
  of 
  them 
  developed 
  Entomophthora 
  and 
  

   Twenty 
  Sporotrichum. 
  all 
  within 
  four 
  days 
  after 
  death. 
  It 
  is 
  to 
  be 
  

   observed 
  that 
  during 
  the 
  two 
  weeks 
  of 
  experiment 
  the 
  number 
  of 
  

   dead 
  specimens 
  developing 
  Entomophthora 
  continued 
  very 
  nearly 
  

   uniform 
  throughout 
  the 
  period, 
  being 
  at 
  the 
  most 
  one 
  or 
  two 
  each 
  

   day, 
  but 
  that 
  the 
  number 
  exhibiting 
  Sporotrichum 
  increased 
  towards 
  

   the 
  last 
  with 
  the 
  increased 
  number 
  of 
  deaths. 
  I 
  see 
  nothing 
  in 
  these 
  

   •observations 
  to 
  indicate 
  that 
  parasitism 
  by 
  Sporotrichum 
  glohnliferioii 
  

   had 
  not 
  as 
  much 
  to 
  do 
  with 
  the 
  death 
  of 
  these 
  bugs 
  as 
  that 
  by 
  Ento- 
  

   inophihova 
  aphidis. 
  Its 
  recognizable 
  occurrence 
  as 
  an 
  external 
  

   growth, 
  often 
  within 
  twenty-four 
  hours, 
  at 
  farthest, 
  of 
  the 
  death 
  of 
  

   the 
  insect 
  — 
  a 
  post-))wrtcm 
  appearance 
  on 
  the 
  whole 
  very 
  nearly 
  as 
  

   prompt 
  as 
  that 
  of 
  the 
  acknowledged 
  pure 
  parasite 
  Entomophthora. 
  

   seems 
  to 
  admit 
  of 
  no 
  other 
  interpretation. 
  

  

  Julij 
  21. 
  The 
  heaviest 
  rain 
  of 
  the 
  season 
  had 
  fallen 
  here, 
  begin-^ 
  

   ning 
  on 
  the 
  afternoon 
  of 
  July 
  19 
  and 
  continuing 
  with 
  great 
  violence 
  

   and 
  almost 
  without 
  interruption 
  for 
  several 
  hours 
  at 
  a 
  time. 
  Mr. 
  

   Snow, 
  who 
  reported 
  the 
  observations 
  of 
  this 
  trip, 
  thought 
  five 
  inches 
  

   of 
  rainfall 
  a 
  conservative 
  estimate. 
  Streams 
  were 
  over 
  the 
  banks 
  

   everywhere, 
  in 
  some 
  places 
  endangering 
  the 
  wooden 
  bridges. 
  Roads 
  

   were 
  flooded 
  in 
  many 
  places, 
  roadside 
  ditches 
  were 
  running 
  over 
  and 
  

   water 
  was 
  standing 
  in 
  the 
  fields. 
  Moderate 
  rain 
  was 
  still 
  falling 
  

   when 
  fields 
  at 
  this 
  place 
  were 
  examined. 
  

  

  According 
  to 
  a 
  careful 
  comparison 
  of 
  the 
  number 
  of 
  chinch-bugs 
  

   In 
  a 
  selected 
  field 
  with 
  those 
  observed 
  by 
  Mr. 
  Snow 
  in 
  the 
  same 
  fields 
  

   ])reviously. 
  no 
  more 
  than 
  twenty-five 
  per 
  cent, 
  of 
  the 
  bugs 
  remained 
  

   in 
  the 
  corn. 
  Eggs 
  and 
  newly 
  hatched 
  young 
  were 
  found, 
  though 
  not 
  

   in 
  great 
  numbers. 
  Except 
  for 
  the 
  immediate 
  effect 
  of 
  the 
  weather 
  

   the 
  causes 
  of 
  this 
  diminution 
  were 
  obscure. 
  Evidences 
  of 
  contagious 
  

   <lisease 
  were 
  but 
  slight, 
  a 
  dead 
  bug 
  covered 
  with 
  a 
  fresh 
  growth 
  of 
  

   either 
  Sporotrichum 
  or 
  Entomophthora 
  being 
  only 
  rarely 
  found.
