﻿FACKAUD] 
  THE 
  LOCUST 
  IN 
  WYOMING. 
  601 
  

  

  These 
  facts, 
  if 
  added 
  to 
  the 
  experience 
  of 
  the 
  last 
  three 
  years 
  in 
  Kansas, 
  Nebraska, 
  

   Dakota, 
  Minnesota, 
  and 
  Manitoba, 
  will 
  suffice 
  to 
  show, 
  not 
  only 
  how 
  extensive 
  their 
  

   range 
  is, 
  but 
  also 
  how 
  varied 
  their 
  flight 
  is, 
  and 
  that 
  there 
  are 
  no 
  particular 
  spots 
  

   which 
  can 
  be 
  said 
  to 
  form 
  their 
  permanent 
  hatching-grounds. 
  That 
  they 
  prefer 
  the 
  

   elevated 
  sandy 
  plateaus 
  and 
  terraces 
  in 
  the 
  mountain 
  districts 
  is 
  certain, 
  but 
  that 
  any 
  

   particular 
  localities 
  form 
  the 
  permanent 
  hives 
  from 
  which 
  the 
  swarm 
  issue 
  cannot 
  be 
  

   maintained. 
  Yet 
  that 
  those 
  which 
  visit 
  Kansas 
  and 
  Nebraska, 
  and 
  even 
  Dakota 
  and 
  

   Minnesota, 
  originate 
  usually 
  within 
  a 
  certain 
  portion 
  of 
  the 
  mountain 
  region 
  appears 
  

   highly 
  probable. 
  While 
  there 
  are 
  some 
  exceptions 
  to 
  the 
  rule, 
  yet 
  it 
  is 
  evident 
  that 
  the 
  

   general 
  course 
  of 
  their 
  flight 
  east 
  of 
  the 
  mountains 
  is 
  southeast. 
  The 
  distance 
  trav- 
  

   eled 
  by 
  any 
  particular 
  swarm, 
  so 
  far 
  as 
  I 
  am 
  aware, 
  has 
  never 
  been 
  positively 
  ascer- 
  

   tained, 
  yet 
  enough 
  is 
  known 
  to 
  indicate 
  that 
  this 
  may 
  extend 
  for 
  at 
  least 
  two 
  or 
  three 
  

   hundred 
  miles. 
  The 
  hordes 
  which 
  visited 
  Colorado 
  in 
  1864 
  are 
  supposed 
  by 
  Colonel 
  

   Byers 
  to 
  have 
  originated 
  in 
  Montana, 
  along 
  the 
  Yellowstone 
  ; 
  and 
  the 
  swarm 
  which 
  I 
  

   traced 
  through 
  Sweetwater 
  Valley 
  probably 
  traveled 
  over 
  200 
  miles 
  ; 
  yet 
  the 
  evidence 
  

   is 
  not 
  positive 
  in 
  either 
  case, 
  though 
  strongly 
  presumptive. 
  

  

  Maj. 
  J. 
  W. 
  Powell 
  informs 
  me 
  that 
  in 
  August, 
  1867, 
  he 
  encountered 
  

   vast 
  numbers 
  of 
  locusts 
  in 
  the 
  region 
  northwest 
  of 
  Pike's 
  Peak, 
  as 
  he 
  

   drove 
  his 
  wagons 
  for 
  five 
  days 
  through 
  them, 
  traveling 
  at 
  the 
  rate 
  of 
  20 
  

   miles 
  a 
  day. 
  It 
  is 
  not 
  probable 
  that 
  this 
  was 
  C. 
  spretus. 
  

  

  In 
  August, 
  1875, 
  Mr. 
  P. 
  K. 
  Uhler 
  visited 
  Colorado, 
  and 
  sends 
  me 
  the 
  

   following 
  notes 
  on 
  G. 
  spretus 
  : 
  

  

  When 
  I 
  first 
  reached 
  Golden, 
  on 
  August 
  6, 
  small 
  flocks 
  of 
  the 
  C 
  spretus 
  were 
  flying 
  

   from 
  the 
  direction 
  of 
  northwest 
  (over 
  the 
  peaks 
  evidently) 
  and 
  alighting 
  on 
  the 
  hills 
  

   and 
  upon 
  the 
  crops 
  in 
  the 
  irrigated 
  tields; 
  but 
  these 
  were 
  nothing 
  to 
  the 
  hordes 
  which 
  

   poured 
  into 
  the 
  country 
  near 
  Manitou 
  about 
  August 
  13-16. 
  

  

  All 
  the 
  flocks 
  that 
  I 
  saw 
  consisted 
  of 
  C. 
  S2}reius. 
  I 
  met 
  with 
  this 
  species 
  everywhere, 
  

   from 
  north 
  of 
  Denver 
  to 
  south 
  of 
  Canon 
  City, 
  in 
  the 
  mountains 
  and 
  on 
  the 
  plains. 
  But 
  

   I 
  did 
  not 
  see 
  them 
  as 
  far 
  east 
  as 
  Bijou. 
  Perhaps 
  they 
  don't 
  love 
  that 
  h)cality. 
  And 
  

   I 
  noticed 
  that 
  the 
  flocks 
  alighted 
  in 
  particular 
  spots, 
  and 
  did 
  not 
  appear 
  all, 
  over 
  the 
  

   plains 
  and 
  hills 
  west 
  of 
  Colorado 
  Springs. 
  Evidently 
  they 
  preferred 
  some 
  spots 
  to 
  

   others 
  of 
  the 
  same 
  kind 
  of 
  surface-soil. 
  

  

  In 
  the 
  Proceedings 
  of 
  the 
  Davenport 
  Academy 
  of 
  Sciences, 
  Mr, 
  J. 
  D. 
  

   Putnatn 
  writes 
  as 
  follows 
  regarding 
  his 
  experience 
  with 
  the 
  locust 
  in 
  

   Colorado 
  : 
  

  

  I 
  have 
  collected 
  this 
  species 
  in 
  various 
  parts 
  of 
  Colorado. 
  It 
  was 
  quite 
  plentiful 
  on 
  

   the 
  plains 
  between 
  Denver 
  and 
  Boulder 
  City 
  in 
  June, 
  1H72, 
  and 
  later 
  in 
  the 
  season 
  I 
  

   found 
  it 
  abimdant 
  in 
  the 
  mountains 
  at 
  Empire 
  City. 
  On 
  August 
  1 
  they 
  were 
  very 
  

   abundant 
  hi^ 
  up 
  above 
  the 
  timber-line 
  on 
  Parry's 
  Peak. 
  Vast 
  numbers 
  were 
  chilled 
  

   by 
  the 
  snow 
  and 
  lay 
  at 
  the 
  base 
  of 
  the 
  snow-drifts 
  in 
  heai)s. 
  They 
  could 
  be 
  seen, 
  filling 
  

   the 
  air 
  like 
  snow-flakes, 
  to 
  a 
  great 
  height 
  above 
  the 
  extreme 
  summit 
  of 
  the 
  peak, 
  

   13,133 
  feet. 
  The 
  wind 
  v/as 
  from 
  a 
  westerly 
  direction. 
  In 
  September, 
  this 
  year 
  (1872), 
  I 
  

   found 
  them 
  in 
  great 
  abundance 
  in 
  Middle 
  Park. 
  In 
  1874 
  I 
  first 
  noticed 
  this 
  species 
  on 
  

   Gold 
  Hill, 
  Boulder 
  County, 
  July 
  B, 
  and 
  on 
  July 
  11 
  they 
  appeared 
  at 
  Valmont 
  and 
  other 
  

   places 
  on 
  the 
  plains 
  in 
  great 
  abundance, 
  and 
  did 
  great 
  damage. 
  They 
  received 
  several 
  

   large 
  re-enforcements 
  during 
  the 
  following 
  week. 
  After 
  remaining 
  several 
  daj's, 
  these 
  

   seemed 
  to 
  disappear, 
  but 
  only 
  to 
  make 
  room 
  for 
  another 
  swarm; 
  and 
  thus 
  they 
  kept 
  

   coming 
  and 
  going 
  during 
  the 
  rest 
  of 
  the 
  summer 
  uniil 
  nothing 
  eatable 
  was 
  left. 
  At 
  

   Empire 
  City 
  they 
  were 
  very 
  abundant 
  during 
  the 
  whole 
  of 
  my 
  stay, 
  from 
  August 
  to 
  

   October, 
  but 
  they 
  seemed 
  to 
  eat 
  but 
  very 
  little, 
  if 
  anything. 
  At 
  Canon 
  City, 
  in 
  Octo- 
  

   ber, 
  I 
  found 
  them 
  very 
  abundant. 
  They 
  were 
  very 
  sluggish, 
  and 
  the 
  sidewalks 
  were 
  

   covered 
  with 
  the 
  dead 
  and 
  dying. 
  Large 
  numbers 
  were 
  seen 
  paired. 
  The 
  young 
  grass- 
  

   hoppers 
  hatched 
  out 
  abundantly 
  early 
  in 
  April, 
  1875. 
  In 
  1873 
  I 
  found 
  them 
  in 
  different 
  

   parts 
  of 
  Western 
  Wyoming, 
  between 
  Fort 
  Bridger 
  and 
  the 
  Yellowstone 
  Lake; 
  but 
  on 
  

   the 
  plains 
  bordering 
  the 
  Stinking 
  Water 
  Eiver, 
  in 
  July, 
  they 
  were 
  more 
  abuudantthan 
  

   I 
  had 
  ever 
  seen 
  them 
  elsewhere 
  before. 
  In 
  June, 
  1875, 
  1 
  collected 
  a 
  few 
  near 
  the 
  trans- 
  

   fer 
  depot 
  at 
  Council 
  Bluffs, 
  Iowa. 
  This 
  is 
  the 
  most 
  eastern 
  locality 
  I 
  have 
  yet 
  seen 
  it. 
  

   Iq 
  Utah 
  last 
  summer 
  I 
  failed 
  to 
  see 
  a 
  single 
  specimen, 
  although 
  I 
  looked 
  specially 
  for 
  

   it.

  THE 
  LOCUST 
  IN 
  WYOMING. 
  

  

  In 
  going 
  from 
  Cheyenne 
  to 
  Salt 
  Lake 
  City, 
  July 
  19 
  and 
  20, 
  over 
  the 
  

   Union 
  Pacific 
  Railroad, 
  no 
  locust 
  was 
  seen, 
  and 
  the 
  absence 
  of 
  insect- 
  

   life 
  wilhiu 
  the 
  limits 
  of 
  Wyoming 
  was 
  remarkable. 
  As 
  soon 
  as 
  the
