  differing 
  from 
  that 
  figured 
  on 
  p. 
  317 
  of 
  our 
  First 
  Report 
  in 
  nothing 
  but 
  

   its 
  slightly 
  larger 
  size. 
  Of 
  it 
  he 
  says 
  : 
  

  

  We 
  have 
  (to 
  us) 
  a 
  new 
  locust 
  exterminator, 
  that 
  in 
  certain 
  localities 
  kills 
  and 
  buries 
  

   large 
  numbers. 
  It 
  appears 
  to 
  kill 
  the 
  locust 
  by 
  stinging 
  him, 
  thrusting 
  into 
  his 
  body 
  

   an 
  egg 
  which 
  hatches 
  in 
  a 
  few 
  days 
  into 
  a 
  little 
  grub. 
  

  

  The 
  same 
  species 
  is 
  referred 
  to 
  by 
  Prof. 
  J. 
  G. 
  Lemmon 
  in 
  a 
  letter 
  dated 
  

   Sierra 
  Valley, 
  California, 
  July 
  18, 
  1880 
  : 
  

  

  I 
  hear 
  much 
  and 
  see 
  a 
  few 
  specimens 
  of 
  a 
  species 
  of 
  Pompil 
  us, 
  which 
  has 
  been 
  seen 
  

   very 
  active 
  in 
  catching, 
  stinging, 
  and 
  dragging 
  locusts 
  into 
  holes 
  dug 
  in 
  the 
  sand, 
  and 
  

   covering 
  them 
  hastily 
  — 
  then 
  seize 
  new 
  victims 
  in 
  rapid 
  succession.

  COURSES 
  THAT 
  MAY 
  BE 
  ADOPTED 
  BY 
  THE 
  GENERAL 
  GOV- 
  

   ERNMENT 
  TO 
  LESSEN 
  LOCUST 
  INJURY. 
  

  

  The 
  First 
  Report 
  of 
  the 
  Commissiou 
  was 
  the 
  result 
  of 
  labors 
  directed 
  

   against 
  the 
  unfledged 
  locusts 
  as 
  they 
  hatch 
  out 
  in 
  the 
  more 
  fertile 
  por- 
  

   tions 
  of 
  the 
  Mississippi 
  Valley 
  and 
  ravage 
  the 
  crops 
  in 
  what 
  we 
  have 
  

   designated 
  as 
  the 
  Temporary 
  region. 
  An 
  equally 
  important 
  — 
  nay, 
  more 
  

   important 
  — 
  problem 
  left 
  for 
  solution 
  was 
  how 
  best 
  to 
  destroy 
  the 
  insect 
  

   in 
  its 
  native 
  or 
  permanent 
  breeding-grounds, 
  or 
  how 
  to 
  prevent 
  the 
  de- 
  

   structive 
  migrations 
  of 
  the 
  winged 
  insects 
  from 
  the 
  Permanent 
  region 
  

   to 
  the 
  more 
  thickly 
  settled 
  and 
  fertile 
  country. 
  As 
  intimated 
  two 
  years 
  

   ago, 
  the 
  solution 
  of 
  this 
  problem, 
  if 
  at 
  all 
  possible, 
  would 
  require 
  sev- 
  

   eral 
  years 
  of 
  investigation. 
  The 
  writer 
  has 
  been 
  deeply 
  impressed 
  with 
  

   the 
  importance 
  of 
  concentrating 
  all 
  efforts 
  of 
  the 
  Commission 
  to 
  the 
  

   obtaining 
  of 
  facts 
  that 
  bear 
  directly 
  on 
  this 
  important 
  question. 
  Of 
  

   the 
  different 
  means 
  that 
  have 
  been 
  suggested 
  we 
  mentioned 
  six 
  more 
  

   particularly, 
  in 
  our 
  first 
  report, 
  and 
  discussed 
  some 
  of 
  them 
  hopefully, 
  

   as 
  follows 
  : 
  

  

  " 
  1. 
  The 
  protection 
  and 
  encouragement 
  to 
  the 
  increase 
  of 
  the 
  native 
  

   locust-feeding 
  birds. 
  2. 
  The 
  introduction 
  of 
  foreign 
  locust-feeding 
  birds. 
  

   3. 
  Inducements 
  offered 
  to 
  the 
  Indians 
  to 
  collect 
  and 
  destroy 
  the 
  eggs 
  

   and 
  young. 
  4. 
  Destroying 
  the 
  eggs 
  or 
  young 
  by 
  making 
  the 
  greatest 
  

   possible 
  use 
  by. 
  artificial 
  means 
  of 
  the 
  natural 
  water-supply. 
  5. 
  Burn- 
  

   ing 
  the 
  young 
  in 
  spring. 
  6. 
  Diverting 
  winged 
  swarms 
  by 
  means 
  of 
  

   smoke. 
  

  

  " 
  While 
  every 
  one 
  of 
  these 
  suggestions 
  might 
  be 
  carried 
  out 
  in 
  excep- 
  

   tional 
  cases 
  to 
  advantage, 
  and 
  while 
  it 
  is 
  the 
  intention 
  of 
  the 
  Commission 
  

   to 
  endeavor 
  to 
  acclimate 
  certain 
  foreign 
  locust-feeding 
  birds, 
  339 
  yet 
  the 
  

  

  339 
  In 
  the 
  summer 
  of 
  1878, 
  with 
  the 
  cooperation 
  of 
  Mr. 
  Montague 
  R. 
  Leverson, 
  of 
  Lev- 
  

   erson 
  Eanch, 
  Douglas 
  County, 
  Colorado, 
  we 
  imported 
  two 
  dozen 
  English 
  rooks 
  with 
  

   a 
  view 
  of 
  sending 
  them 
  out 
  to 
  be 
  acclimated 
  in 
  Colorado 
  and 
  in 
  the 
  belief 
  that 
  this 
  

   bird 
  would 
  prove 
  one 
  of 
  the 
  most 
  useful 
  to 
  acclimate 
  there. 
  The 
  birds 
  were 
  badly 
  

   handled 
  on 
  the 
  voyage 
  and 
  detained 
  in 
  the 
  custom-house 
  in 
  New 
  York, 
  and 
  we
