  Weather 
  very 
  dry, 
  roads 
  extremely 
  dusty. 
  Found 
  very 
  

   few 
  nearly 
  dead 
  adults 
  and 
  a 
  few 
  dead 
  young, 
  all 
  covered 
  with 
  

   Sporotricluim. 
  No 
  change

  — 
  April 
  14. 
  Several 
  fields 
  on 
  various 
  

   farms 
  near 
  Odin, 
  and 
  between 
  that 
  town 
  and 
  the 
  next 
  railroad 
  sta- 
  

   tion 
  north 
  (Tonti) 
  were 
  examined 
  with 
  reference 
  to 
  the 
  numbers, 
  

   location, 
  and 
  condition 
  of 
  the 
  chinch-bugs 
  just 
  emerging 
  from 
  their 
  

   hibernating 
  period. 
  Collections 
  were 
  also 
  brought 
  to 
  the 
  laboratory 
  

   from 
  these 
  fields 
  for 
  observation 
  in 
  confinement, 
  with 
  a 
  view 
  to 
  as- 
  

   certaining 
  whether 
  the 
  occurrence 
  of 
  contagious 
  disease 
  in 
  any 
  form 
  

   might 
  be 
  detected 
  among 
  them 
  at 
  this 
  season. 
  This 
  last 
  inquiry 
  was 
  

   especially 
  interesting 
  because 
  some 
  of 
  the 
  fields 
  examined 
  were 
  those 
  

   in 
  which 
  the 
  so-called 
  white 
  muscardine 
  of 
  the 
  chinch-bug 
  had 
  been 
  

   quite 
  prevalent 
  the 
  preceding 
  autumn. 
  The 
  weather 
  at 
  the 
  time 
  of 
  

   this 
  visit 
  had 
  been 
  somewhat 
  stormy 
  for 
  several 
  days, 
  with 
  light 
  rain 
  

   and 
  considerable 
  wind. 
  This 
  rain 
  had 
  been 
  preceded 
  by 
  snow, 
  and 
  

   this 
  again 
  by 
  a 
  warm 
  spell 
  during 
  which 
  a 
  few 
  old 
  bugs 
  had 
  been 
  

   noticed 
  on 
  the 
  wing. 
  The 
  bugs 
  were 
  still 
  mostly 
  in 
  their 
  winter 
  

   ([uarters 
  under 
  leaves 
  and 
  hedges 
  and 
  rails 
  lying 
  upon 
  the 
  ground, 
  

   among 
  roots 
  of 
  blue 
  grass 
  and 
  timothy 
  at 
  the 
  borders 
  of 
  fields, 
  

   around 
  stumps 
  in 
  a 
  meadow, 
  in 
  corn 
  fields, 
  and 
  occasionally 
  in 
  the 
  

   shocks 
  of 
  corn, 
  and 
  once 
  found 
  in 
  an 
  old 
  wheat 
  field 
  at 
  the 
  base 
  of 
  the 
  

   stubble 
  of 
  the 
  preceding 
  year. 
  They 
  were 
  most 
  abundant 
  at 
  this 
  sea- 
  

   son 
  along 
  a 
  rail 
  fence 
  bordering 
  a 
  woodland 
  and 
  in 
  the 
  grass 
  about 
  

   the 
  fallen 
  rails. 
  A 
  few 
  were 
  seen 
  upon 
  the 
  wing. 
  But 
  very 
  few 
  

   dead 
  bugs 
  were 
  found 
  in 
  these 
  winter 
  quarters, 
  although 
  search 
  for 
  

   these 
  was 
  one 
  of 
  the 
  principal 
  objects 
  of 
  the 
  trip. 
  Along 
  the 
  fence 
  

   above 
  mentioned, 
  for 
  example, 
  where 
  the 
  old 
  bugs 
  were 
  present 
  in 
  

   millions, 
  not 
  one 
  dead 
  specimen 
  was 
  found. 
  Only 
  three 
  exhibiting 
  

   the 
  muscardine 
  fungus 
  were 
  reported 
  for 
  this 
  trip, 
  and 
  there 
  was 
  of 
  

   course 
  no 
  assurance 
  that 
  these 
  had 
  been 
  killed 
  by 
  the 
  fungus 
  para- 
  

   site. 
  Four 
  lots 
  of 
  specimens 
  were 
  kept 
  for 
  some 
  days 
  at 
  the 
  labora- 
  

   tory 
  under 
  conditions 
  to 
  demonstrate 
  the 
  occurrence 
  of 
  fungous 
  

   disease 
  among 
  them 
  if 
  present. 
  Three 
  of 
  these 
  lots 
  gave 
  no 
  definite 
  

   evidence 
  of 
  its 
  occurrence, 
  while 
  in 
  the 
  fourth 
  white 
  muscardine 
  

   appeared. 
  

  

  Api'd 
  ?.s. 
  Fence 
  rows 
  and 
  other 
  hibernating 
  quarters 
  had 
  been 
  

   abandoned 
  by 
  the 
  bugs, 
  and 
  wheat 
  fields 
  were 
  already 
  badly 
  infested. 
  

   No 
  diseased 
  bugs 
  of 
  any 
  kind 
  were 
  found 
  in 
  these 
  fields 
  and 
  only 
  

   one 
  specimen 
  of 
  white 
  muscardine 
  was 
  detected 
  in 
  the 
  winter 
  quar- 
  

   ters: 
  but 
  a 
  collection 
  brought 
  to 
  the 
  laboratory 
  April 
  29

  kept 
  in 
  

   confinement

  Young 
  bugs 
  of 
  the 
  first 
  and 
  second 
  stages 
  were 
  now 
  ex- 
  

   tremely 
  abundant 
  in 
  young 
  wheat, 
  reddening 
  tlie 
  steins 
  and 
  dwarfing 
  

   and 
  killing 
  the 
  plants. 
  The 
  adults 
  were 
  still 
  pairing 
  in 
  small 
  num- 
  

   bers 
  and 
  a 
  very 
  few 
  eggs 
  were 
  seen. 
  A 
  considerable 
  number 
  of 
  

   adults 
  were 
  also 
  noticed 
  covered 
  with 
  Sporotrichum, 
  most 
  abundantly 
  

   at 
  the 
  bases 
  of 
  the 
  plants. 
  A 
  few 
  dead 
  bugs 
  were 
  seen 
  after 
  a 
  

   rain 
  in 
  dead 
  furrows 
  and 
  other 
  places 
  which 
  had 
  received 
  the 
  wash 
  

   of 
  the 
  field, 
  but 
  no 
  fungous 
  growth 
  except 
  on 
  dead 
  adults.
