   Oats 
  and 
  corn 
  generally 
  free 
  from 
  bugs 
  or 
  containing 
  very 
  few 
  

   except 
  adjacent 
  to 
  infested 
  wheat 
  which 
  had 
  been 
  partly 
  liar- 
  

   vested. 
  From 
  this 
  bugs 
  had 
  scattered 
  to 
  oats 
  and 
  meadow 
  grass^ 
  

   but 
  had 
  concentrated 
  especially 
  upon 
  the 
  outer 
  hills 
  of 
  the 
  corn 
  to 
  a 
  

   dej)th 
  of 
  about 
  twenty-tive 
  rows, 
  averaging 
  according 
  to 
  the 
  observer's- 
  

   estimate 
  a 
  measured 
  ounce 
  to 
  each 
  hill. 
  Had 
  gone 
  into 
  oats 
  about 
  

   fifteen 
  feet, 
  killing 
  a 
  strip

  width. 
  Many 
  dead 
  

   found 
  in 
  both 
  wheat 
  and 
  oats, 
  several 
  at 
  the 
  base 
  of 
  each 
  stool 
  in 
  the- 
  

   wheat, 
  and 
  so 
  abundant 
  in 
  the 
  oats 
  that 
  in 
  moist 
  places 
  they 
  were 
  

   scattered 
  at 
  an 
  average 
  distance 
  of 
  an 
  inch 
  apart. 
  In 
  the 
  wheat 
  

   stubble 
  dead 
  were 
  also 
  found, 
  together 
  with 
  scattered 
  young. 
  A 
  

   large 
  number 
  were 
  collected 
  from

  at 
  this 
  place 
  and 
  brought 
  to- 
  

   my 
  laboratory 
  for 
  the

   cause 
  of 
  death.
