  When 
  eggs 
  are 
  not 
  disturbed 
  by 
  tbe 
  plow 
  frost 
  does 
  not 
  destroy 
  them. 
  During 
  the 
  

   years 
  named 
  they 
  visited 
  all 
  parts 
  of 
  the 
  Territory. 
  Thousands 
  of 
  bushels 
  wore 
  de- 
  

   stroyed 
  by 
  the 
  organized 
  labors 
  of 
  the 
  people, 
  by 
  driving 
  them 
  and 
  burying 
  them 
  in 
  

   trenches, 
  by 
  setting 
  traps 
  in 
  irrigating 
  ditches, 
  by 
  covering 
  the 
  ground 
  with 
  straw, 
  

   under 
  which 
  they 
  would 
  shelter 
  for 
  the 
  night, 
  and 
  in 
  the 
  morning 
  burning 
  the 
  straw 
  

   and 
  insects. 
  Men, 
  women, 
  and 
  children, 
  with 
  the 
  village 
  poultry, 
  in 
  some 
  places, 
  

   moved 
  to 
  the 
  fields 
  in 
  wagons 
  and 
  fought 
  the 
  common 
  enemy 
  from 
  hatching 
  to 
  flying 
  

   time. 
  In 
  some 
  parts, 
  it 
  was 
  estimated 
  there 
  were 
  one 
  hundred 
  bushels 
  of 
  hoppers 
  to 
  

   the 
  acre. 
  

  

  A 
  notable 
  local 
  mathematician 
  estimated 
  that 
  in 
  one 
  sea^son, 
  one 
  and 
  a 
  half 
  million 
  

   lushela 
  were 
  destroyed 
  by 
  lighting 
  in 
  Great 
  Salt 
  Lake 
  and 
  drifting 
  on 
  the 
  shores, 
  form- 
  

   ing 
  an 
  immense 
  belt. 
  

  

  THE 
  LOCUST 
  IN 
  NEW 
  MEXICO. 
  

  

  Professor 
  Thomas 
  also 
  states 
  that 
  it 
  breeds 
  in 
  Snake 
  Valley, 
  Idaho. 
  

   That 
  it 
  is 
  common 
  and 
  destructive 
  at 
  times 
  in 
  New 
  Mexico 
  is 
  shown 
  

   irom 
  the 
  statement 
  published 
  in 
  the 
  Monthly 
  Report 
  of 
  the 
  Depart- 
  

   ment 
  of 
  Agriculture, 
  at 
  Washington, 
  D. 
  C, 
  for 
  July, 
  1876, 
  where 
  it 
  is 
  

   stated 
  that 
  the 
  corn 
  and 
  oats 
  were 
  iujured 
  and 
  the 
  wheat-crop 
  half 
  

   destroyed 
  by 
  the 
  " 
  grasshopper," 
  which 
  must 
  be 
  C. 
  spretus, 
  as 
  Taos 
  is 
  

   near 
  the 
  Colorado 
  liue. 
  Professor 
  Thomas 
  reports 
  a 
  few 
  specimens 
  of 
  

   C. 
  spretus 
  from 
  New 
  Mexjco 
  and 
  Arizona 
  in 
  collections 
  made 
  by 
  Lieu- 
  

   tenant 
  Wheeler's 
  Expeditions 
  during 
  the 
  last 
  four 
  years, 
  and 
  he 
  himself 
  

   found 
  a 
  few 
  specimens 
  south 
  of 
  Eaton 
  Mountains 
  in 
  1869. 
  In 
  1875, 
  

   however, 
  Lieutenant 
  Carpenter, 
  as 
  he 
  writes 
  me, 
  did 
  not 
  see 
  any 
  swarms 
  

   in 
  the 
  region 
  extending 
  from 
  Fort 
  Garland 
  to 
  Santa 
  Fe. 
  " 
  I 
  could 
  not 
  

   learn," 
  he 
  adds, 
  " 
  that 
  they 
  had 
  ever 
  been 
  troublesome 
  in 
  northern 
  

   New 
  Mexico." 
  

  

  THE 
  LOCUST 
  IN 
  NEVADA. 
  

  

  Prof 
  Cyrus 
  Thomas 
  has 
  kindly 
  afforded 
  me 
  the 
  following 
  facts 
  regard- 
  

   ing 
  the 
  occurrence 
  of 
  Caloptenus 
  spretus 
  in 
  Nevada, 
  in 
  a 
  letter 
  dated 
  

   March 
  1, 
  1877 
  : 
  

  

  I 
  saw 
  C. 
  spretus 
  in 
  1871 
  in 
  ab"undance 
  along 
  the 
  Humboldt 
  River 
  in 
  Nevada, 
  most 
  of 
  

   the 
  way 
  from 
  where 
  the 
  Central 
  Pacific 
  Railroad 
  strikes 
  it 
  (going 
  west) 
  to 
  the 
  sink 
  

   or 
  place 
  where 
  it 
  disappears. 
  At 
  one 
  point 
  they 
  were 
  quite 
  abundant, 
  and 
  evidently 
  

   preparing 
  to 
  migrate, 
  flying 
  up 
  in 
  the 
  air, 
  their 
  wings 
  presenting 
  that 
  peculiar 
  glassy, 
  

   snowy 
  appearance 
  with 
  which 
  you 
  are 
  no 
  doubt 
  familiar. 
  This, 
  if 
  I 
  recollect 
  rightly, 
  

   was 
  west 
  of 
  Humboldt 
  Station 
  ; 
  they 
  were 
  quite 
  abundant 
  at 
  that 
  station 
  (Humboldt), 
  

   where 
  we 
  dined, 
  (going 
  west), 
  but 
  were 
  noc 
  migrating 
  there 
  or 
  then 
  ; 
  those 
  referred 
  

   to 
  as 
  seen 
  west 
  of 
  Humboldt 
  being 
  seen 
  as 
  we 
  returned 
  east. 
  You 
  probably 
  remember 
  

   that 
  saline 
  or 
  alkaline 
  belt 
  at 
  the 
  northwest 
  extremity 
  of 
  Great 
  Salt 
  Lake 
  ; 
  just 
  beyond 
  

   that 
  I 
  began 
  to 
  observe 
  them, 
  and 
  from 
  thence 
  — 
  not 
  continuously, 
  but 
  at 
  certain 
  

   points 
  — 
  from 
  there 
  to, 
  and 
  a, 
  short 
  distance 
  west 
  of, 
  Humboldt 
  Sink. 
  The 
  collections 
  

   made 
  by 
  Wheeler's 
  party 
  in 
  S;iuthea8t 
  Nevada 
  had 
  no 
  specimens 
  which 
  I 
  could 
  posi- 
  

   tively 
  say 
  came 
  from 
  that 
  section. 
  That 
  year 
  (1871), 
  as 
  we 
  went 
  out 
  (June), 
  we 
  saw 
  

   but 
  few 
  specimens 
  in 
  Salt 
  Lake 
  Valley, 
  but 
  they 
  were 
  quite 
  numerous 
  when 
  we 
  re- 
  

   turned 
  from 
  California 
  in 
  August. 
  They 
  were 
  also 
  numerous 
  in 
  Cache 
  Valley 
  and 
  

   Southern 
  Idaho 
  ; 
  in 
  moderate 
  numbers 
  west 
  of 
  the 
  range 
  in 
  Montana 
  as 
  well 
  as 
  east. 
  

  

  From 
  the 
  facts 
  thus 
  afforded 
  by 
  Professor 
  Thomas, 
  it 
  is 
  not 
  improb- 
  

   able 
  that 
  this 
  species 
  in 
  its 
  normal 
  form 
  will 
  be 
  found 
  to 
  commonly 
  occur 
  

   in 
  the 
  treeless 
  regions 
  of 
  the 
  entire 
  State 
  of 
  Nevada, 
  and 
  also 
  of 
  the 
  east- 
  

   ern 
  half 
  of 
  Oregon, 
  and 
  also, 
  perhaps, 
  of 
  Washington 
  Territory, 
  west 
  

   of 
  the 
  Sierra 
  Nev^ada, 
  to 
  the 
  south, 
  and 
  the 
  Cascade 
  Mountains 
  to 
  the 
  

   north. 
  Among 
  these 
  ranges, 
  and 
  to 
  the 
  westward, 
  when 
  the 
  rain-fall 
  

   is 
  very 
  con.«iderable, 
  and 
  the 
  land 
  clothed 
  with 
  forests, 
  we 
  are 
  to 
  look 
  

   for 
  the 
  non-migratory 
  variety, 
  Atlanis, 
  which 
  may 
  there 
  exist 
  under 
  

   conditions 
  resembling 
  those 
  in 
  which 
  it 
  lives 
  in 
  the 
  Mississippi 
  Valley, 
  

   and 
  the 
  foiest-clad 
  Atlantic 
  States 
  and 
  Canada.
