  THE 
  LOCUST 
  IN 
  COLORADO 
  IN 
  1878. 
  

  

  The 
  Eocky 
  Mountain 
  Locust 
  during 
  the 
  summer 
  of 
  1878 
  bred 
  sparingly 
  

   throughout 
  the 
  mountainous 
  portion 
  of 
  the 
  State. 
  We 
  found 
  them 
  not 
  

   uncommon 
  on 
  the 
  road 
  to 
  Gray's 
  Peak, 
  five 
  or 
  six 
  miles 
  from 
  George- 
  

   town, 
  at 
  an 
  elevation 
  of 
  about 
  9,000 
  feet, 
  August 
  20. 
  On 
  the 
  extreme 
  

   summit 
  of 
  Gray's 
  Peak 
  a 
  few 
  were 
  seen 
  flying 
  by 
  the 
  workmen 
  on 
  the 
  

   Summit 
  House, 
  then 
  building, 
  and 
  I 
  found 
  several 
  under 
  stones, 
  be- 
  

   numbed 
  with 
  the 
  cold. 
  At 
  an 
  elevation 
  of 
  about 
  12,000 
  feet 
  they 
  were 
  

   common 
  on 
  the 
  " 
  alpes," 
  or 
  grassy 
  slopes, 
  leaping 
  and 
  flying 
  when 
  the 
  

   sun 
  was 
  shining. 
  

  

  We 
  were 
  informed 
  that 
  a 
  swarm 
  was 
  seen 
  in 
  South 
  Park, 
  August 
  14 
  y 
  

   flying 
  east 
  for 
  an 
  hour 
  or 
  two. 
  It 
  breeds 
  annually 
  in 
  Snake 
  and 
  Bear 
  

   River 
  Valleys, 
  but 
  none 
  had 
  been 
  seen 
  the 
  present 
  summer 
  in 
  Snake 
  

   Eiver 
  Yalley. 
  

  

  We 
  were 
  also 
  told 
  that 
  August 
  13 
  and 
  14 
  locusts 
  were 
  abundant 
  in 
  

   Estes 
  Park 
  ; 
  they 
  were 
  seen 
  flying 
  in 
  the 
  air 
  in 
  large 
  numbers 
  ; 
  and 
  it 
  

   was 
  feared 
  that 
  they 
  would 
  lay 
  their 
  eggs, 
  the 
  ground 
  being 
  covered 
  with 
  

   them. 
  We 
  were 
  also 
  told 
  that 
  they 
  bred 
  this 
  summer 
  in 
  small 
  quanti- 
  

   ties 
  in 
  Gilpin 
  County, 
  especially 
  on 
  the 
  Bear 
  Mountains. 
  At 
  Summit, 
  

   August 
  26, 
  locusts 
  were 
  observed 
  flying 
  southwest 
  with 
  the 
  wind. 
  (United 
  

   States 
  Weather 
  Signal 
  Eeports.) 
  From 
  these 
  facts 
  we 
  judge 
  that 
  Calop- 
  

   tenus 
  spretus 
  bred 
  sparingly 
  in 
  1878 
  throughout 
  the 
  more 
  elevated 
  por- 
  

   tions 
  of 
  Colorado, 
  not 
  existing 
  in 
  its 
  normal 
  numbers, 
  and 
  nowhere 
  

   sufficiently 
  abundant 
  to 
  gather 
  into 
  large, 
  destructive, 
  migratory 
  swarms 
  r 
  

   though 
  locally 
  migratory. 
  Later 
  in 
  the 
  season 
  we 
  received 
  the 
  following 
  

   information 
  from 
  Mr. 
  William 
  N. 
  Byers 
  : 
  

  

  September 
  10-13 
  I 
  was 
  in 
  Northern 
  Colorado. 
  I 
  found 
  them 
  abundant 
  on 
  White 
  

   Eiver, 
  at 
  White 
  River 
  Indian 
  Agency, 
  and 
  extending 
  up 
  that 
  river 
  four 
  miles 
  (proba- 
  

   ably 
  further) 
  and 
  down 
  it 
  an 
  unknown 
  distance 
  ; 
  also, 
  northward 
  about 
  forty 
  miles, 
  

   diminishing 
  in 
  numbers 
  from 
  south 
  to 
  north 
  ; 
  also, 
  a 
  few 
  along 
  the 
  Upper 
  Bear 
  River 
  

   Valley. 
  They 
  were 
  depositing 
  eggs. 
  

  

  THE 
  LOCUST 
  IN 
  WYOMING 
  IN 
  1878. 
  

  

  Along 
  the 
  line 
  of 
  the 
  Union 
  Pacific 
  Eailroad 
  the 
  locust 
  had 
  not 
  been 
  

   seen 
  this 
  year, 
  except 
  in 
  very 
  limited 
  numbers. 
  Near 
  Summit 
  Station 
  

   they 
  had 
  bred 
  in 
  the 
  bottoms, 
  but 
  only 
  in 
  sufficient 
  quantities 
  for 
  

   bait 
  both 
  this 
  summer 
  and 
  in 
  1877. 
  At 
  Laramie 
  City 
  we 
  were 
  informed
