  UNITED 
  STATES 
  ENTOMOLOGICAL 
  COMMISSION. 
  

  

  by 
  members 
  of 
  the 
  Commission 
  and 
  such 
  energetic 
  farmers 
  as 
  tried 
  to 
  

   save 
  what 
  they 
  could 
  of 
  their 
  crops. 
  

  

  Eemember, 
  also, 
  that 
  every 
  eifort 
  put 
  forth 
  in 
  fighting 
  locusts 
  is 
  so 
  

   much 
  towards 
  their 
  diminution 
  and 
  future 
  immunity 
  from 
  their 
  attacks. 
  

   Every 
  locust 
  that 
  is 
  destroyed 
  before 
  the 
  breeding 
  season 
  subtracts 
  

   about 
  forty 
  from 
  the 
  possible 
  increase 
  the 
  following 
  season. 
  

  

  In 
  speaking 
  of 
  the 
  future 
  in 
  reference 
  to 
  the 
  depredations 
  by 
  locusts 
  

   in 
  Nebraska, 
  Professor 
  S. 
  Aughey 
  says 
  : 
  

  

  When 
  the 
  area 
  under 
  cultivation 
  is 
  trebled, 
  the 
  amount 
  of 
  damage 
  which 
  they 
  can 
  

   do 
  will 
  he 
  more 
  than 
  one-half 
  less. 
  Another 
  more 
  potent 
  agency 
  against 
  their 
  in- 
  

   crease 
  and 
  destructiveness 
  is 
  the 
  increasing 
  rainfall 
  of 
  the 
  State. 
  We 
  have 
  already 
  

   seen 
  how 
  the 
  wet 
  season 
  of 
  1877 
  destroyed 
  the 
  greater 
  part 
  of 
  those 
  that 
  appeared 
  

   that 
  spring. 
  During 
  each 
  coming 
  decade 
  the 
  number 
  of 
  similar 
  seasons 
  will 
  increase. 
  

   The 
  instincts 
  of 
  the 
  locust 
  will 
  also 
  prompt 
  it 
  to 
  remain 
  away 
  from 
  a 
  region 
  so 
  hostile 
  

   to 
  its 
  existence.^ 
  

  

  What 
  is 
  true 
  of 
  Nebraska 
  is 
  also 
  true, 
  to 
  a 
  great 
  extent, 
  of 
  the 
  larger 
  

   part 
  of 
  the 
  Temporary 
  Eegion. 
  

  

  For 
  my 
  part, 
  I 
  am 
  inclined 
  to 
  believe 
  that 
  we 
  have 
  experienced 
  the 
  

   worst 
  raids 
  from 
  this 
  insect, 
  and 
  that 
  if 
  any 
  more 
  visitations 
  are 
  made 
  

   in 
  the 
  future, 
  each 
  successive 
  one 
  will 
  be 
  felt 
  less 
  for 
  reasons 
  heretofore 
  

   mentioned. 
  

  

  THE 
  GENERAL 
  OUTLOOK. 
  

  

  Having 
  devoted 
  so 
  much 
  space 
  to 
  the 
  natural 
  history 
  and 
  habits 
  of 
  

   this 
  locust, 
  it 
  would 
  be 
  well 
  to 
  devote 
  a 
  little 
  space 
  to 
  the 
  probabilities 
  

   of 
  locust 
  visits 
  for 
  1882, 
  and 
  if 
  any 
  should 
  appear, 
  their 
  extent 
  and 
  prob- 
  

   able 
  whereabouts. 
  This 
  can 
  only 
  be 
  approximately 
  stated 
  by 
  using 
  the 
  

   data 
  of 
  1881 
  as 
  a 
  basis. 
  As 
  this 
  insect 
  covered 
  but 
  a 
  comparatively 
  

   small 
  area 
  in 
  the 
  Permanent 
  Eegion 
  within 
  the 
  United 
  States, 
  and 
  in 
  

   regions, 
  too, 
  so 
  widely 
  scattered, 
  we 
  may 
  predict 
  that 
  its 
  depredations 
  

   will 
  not 
  be 
  great 
  the 
  coming 
  summer. 
  

  

  While 
  there 
  weTe 
  a 
  few 
  small 
  flights 
  noticed 
  east 
  of 
  the 
  main 
  divide 
  of 
  

   the 
  Rocky 
  Mountains, 
  the 
  majority 
  of 
  them 
  were 
  confined 
  to 
  the 
  west- 
  

   ern 
  portion 
  of 
  the 
  locust 
  area, 
  heretofore 
  noticed 
  as 
  the 
  central 
  region 
  or 
  

   that 
  of 
  the 
  Snake 
  Eiver 
  Valley. 
  A 
  few 
  small 
  swarms 
  were 
  reared 
  at 
  

   various 
  localities 
  in 
  western 
  Montana, 
  northern 
  Idaho, 
  eastern 
  Wasli- 
  

   ington 
  Territory 
  and 
  Oregon, 
  as 
  well 
  as 
  in 
  Nevada 
  and 
  parts 
  of 
  Utah. 
  

   These, 
  although 
  I 
  was 
  unable 
  to 
  obtain 
  sufficient 
  data 
  by 
  which 
  to 
  sub- 
  

   stantiate 
  this 
  supposition, 
  after 
  flying 
  away 
  from 
  the 
  localities 
  in 
  which 
  

   they 
  were 
  reared, 
  came 
  down 
  and 
  deposited 
  their 
  eggs, 
  which, 
  of 
  course, 
  

   will 
  hatch 
  when 
  the 
  x)roper 
  time 
  arrives. 
  These, 
  according 
  to 
  custom, 
  

   will 
  migrate, 
  but 
  in 
  most 
  instances 
  in 
  numbers 
  insufficient 
  to 
  commit 
  

   great 
  depredations. 
  

  

  The 
  first 
  locusts 
  that 
  I 
  noticed 
  or 
  heard 
  of 
  this 
  season 
  were 
  those 
  

   noticed 
  about 
  two 
  o^clock 
  in 
  the 
  afternoon 
  on 
  the 
  6th 
  day 
  of 
  August. 
  

   They 
  were 
  on 
  the 
  wing 
  at 
  tlie 
  time 
  and 
  were 
  flying 
  northward 
  on 
  a 
  stiff
