  preceding 
  year, 
  being 
  mostly 
  confined 
  to 
  stems 
  close 
  to 
  

   the 
  ground 
  and 
  behind 
  sheaths 
  of 
  the 
  leaves. 
  A 
  careful 
  search 
  of 
  

   six 
  fields 
  of 
  wheat 
  and 
  one 
  of 
  rye 
  discovered 
  only 
  one 
  chinch-bug 
  

   with 
  Sporotrichum. 
  Search 
  of 
  dead 
  furrows 
  between 
  drill 
  rows 
  and 
  

   in 
  low 
  spots 
  receiving 
  the 
  wash 
  of 
  the 
  field, 
  brought 
  to 
  light 
  always 
  

   young 
  bugs 
  imbedded 
  in 
  the

  Dead 
  young 
  in 
  very 
  small 
  num- 
  

   bers 
  on 
  the 
  hard 
  surface 
  of 
  the 
  ground 
  between 
  drill 
  rows, 
  but 
  most 
  

   abundant 
  where 
  pools 
  of 
  standing 
  water 
  had 
  disappeared. 
  Young 
  

   chinch-bugs 
  rarely 
  seen 
  still 
  swimming 
  on 
  the 
  surface 
  of 
  standing 
  

   water. 
  A 
  few 
  of 
  those 
  fastened 
  in 
  the 
  mud 
  were 
  still 
  feebly 
  alive, 
  

   but 
  about 
  eighty 
  per 
  cent, 
  of 
  them 
  were 
  dead. 
  Number 
  of 
  dead 
  

   actually 
  seen 
  was 
  small 
  compared 
  with 
  those 
  still 
  living 
  in 
  the 
  fields, 
  

   but 
  doubtless 
  a 
  large 
  proportion 
  of 
  tliosc 
  actually 
  killed 
  were 
  over- 
  

   looked.

  Rain

  ever\' 
  day 
  for 
  about 
  a 
  week,

   wet

  The

  in

   vinusually

  month 
  of 
  May 
  reaching 
  the 
  extraordinary 
  total 
  

   of 
  8.8

  The

  had 
  also 
  been 
  unusually 
  high 
  for 
  

   the

  Chinch-bugs 
  still 
  quite

  a 
  

   few

   Occasionally 
  a

  Apparently 
  not 
  

   less

  many 
  fields

   the 
  outer 
  rows 
  adjacent 
  to 
  fields

  infested 
  grain, 
  where 
  a 
  teaspoon-

  might 
  have 
  been 
  collected 
  from 
  each 
  hill. 
  Scarcely

  No

  seen. 
  The

  Collections 
  of 
  live 
  chinch-bugs 
  brought 
  in 
  from 
  these 
  

   fields 
  were 
  placed 
  in 
  a 
  breeding-box 
  under 
  normal 
  conditions 
  and 
  fed 
  

   each 
  day 
  with 
  freshly 
  cut 
  corn 
  for 
  the 
  purpose 
  of 
  studying 
  the 
  causes 
  

   of 
  such 
  mortality 
  as 
  might 
  appear 
  among 
  them. 
  The 
  specimens 
  

   dead 
  each 
  day 
  were 
  removed 
  and 
  placed 
  upon 
  rpoist 
  sand 
  (in 
  a 
  

   shallow 
  glass 
  tray 
  with 
  an 
  overhanging 
  glass 
  cover) 
  with 
  a 
  view 
  to 
  

   obtaining 
  a

  development 
  of 
  any
