  NEBKASKA 
  DATA. 
  

  

  Hooper, 
  Dodge 
  County, 
  May 
  14, 
  1877. 
  

   The 
  first 
  time 
  I 
  noticed 
  the 
  Rocky 
  Mountain 
  locust 
  in 
  this 
  locality 
  was 
  June 
  or 
  

   July, 
  1859. 
  They 
  have 
  since 
  then, 
  up 
  to 
  the 
  year 
  1866, 
  made 
  short 
  visits, 
  never 
  doing 
  

   any 
  damage 
  to 
  the 
  crops, 
  nor 
  did 
  they 
  at 
  any 
  time 
  leave 
  any 
  eggs 
  behind 
  them. 
  

   About 
  the 
  middle 
  of 
  September 
  of 
  the 
  year 
  last 
  mentioned 
  they 
  came 
  upon 
  us 
  from 
  

   the 
  northwest 
  in 
  full 
  force, 
  and 
  their 
  numbers 
  were 
  legions 
  ; 
  they 
  came, 
  too, 
  to 
  stay 
  

   until 
  the 
  first 
  slight 
  frost 
  in 
  October 
  finished 
  their 
  earth. 
  y 
  existence, 
  seemingly 
  all 
  

   dying 
  in 
  one 
  night 
  ; 
  not 
  until, 
  however, 
  they 
  had 
  left 
  us 
  a 
  large 
  crop 
  of 
  eggs 
  and 
  de- 
  

   stroyed 
  fully 
  one-third 
  of 
  the 
  corn 
  crop. 
  The 
  eggs 
  hatched 
  the 
  following 
  spring, 
  

   numerously 
  in 
  April, 
  and 
  the 
  young 
  pest 
  seemed 
  to 
  outnumber 
  the 
  old 
  swarm, 
  living 
  

   for 
  a 
  time, 
  as 
  it 
  were, 
  to 
  devour 
  everything 
  tinted 
  green, 
  avoiding, 
  after 
  all, 
  the 
  

   tender 
  corn 
  blades. 
  But 
  plenty 
  of 
  moisture 
  and 
  fine 
  growing 
  weather 
  checked 
  their
