  UNITED 
  STATES 
  ENTOMOLOGICAL 
  COMMISSION. 
  

  

  Other 
  plans 
  have 
  been 
  proposed 
  (one 
  or 
  two 
  will 
  be 
  mentioned 
  further 
  

   on 
  under 
  General 
  Remarks), 
  but 
  as 
  most 
  of 
  them 
  are 
  still 
  less 
  feasible 
  and 
  

   show 
  a 
  want 
  of 
  knowledge 
  of 
  the 
  character 
  of 
  the 
  breeding 
  grounds 
  and 
  

   the 
  difficulties 
  to 
  be 
  overcome, 
  it 
  is 
  unnecessary 
  for 
  us 
  to 
  consider 
  them. 
  

   The 
  proposition 
  for 
  the 
  government 
  to 
  burn 
  over 
  the 
  areas 
  of 
  egg 
  deposits 
  

   after 
  the 
  young 
  are 
  hatched 
  out 
  offers 
  some 
  hope 
  as 
  a 
  means 
  of 
  their 
  

   destruction, 
  but, 
  as 
  we 
  have 
  seen, 
  appears 
  to 
  be 
  impracticable 
  with 
  the 
  

   limited 
  population 
  in 
  the 
  permanent 
  region. 
  

  

  Collecting 
  and 
  destroying 
  the 
  eggs 
  and 
  young 
  in 
  the 
  permanent 
  breed- 
  

   ing 
  grounds, 
  which 
  is 
  hereafter 
  noticed, 
  is 
  worthy 
  of 
  careful 
  consideration, 
  

   as 
  it 
  is 
  possible 
  ; 
  but 
  the 
  immense 
  expense 
  it 
  will 
  entail 
  has 
  prevented 
  

   us 
  from 
  mentioning 
  it 
  among 
  the 
  practicable 
  remedies. 
  

  

  We 
  are, 
  therefore, 
  of 
  the 
  opinion 
  that 
  the 
  best 
  plan 
  to 
  be 
  followed 
  is, 
  

   first, 
  to 
  adopt 
  measures 
  to 
  throw 
  an 
  agricultural 
  population 
  into 
  the 
  

   radiating 
  points 
  of 
  the 
  permanent 
  breeding 
  grounds, 
  commencing 
  with 
  

   the 
  portion 
  of 
  Montana 
  designated 
  ; 
  and, 
  if 
  possible, 
  induce 
  the 
  Domin- 
  

   ion 
  Government 
  to 
  unite 
  in 
  this 
  effort 
  so 
  £ar 
  as 
  relates 
  to 
  the 
  region 
  

   immediately 
  north 
  of 
  the 
  international 
  boundary 
  along 
  the 
  east 
  flank 
  of 
  

   the 
  Eocky 
  Mountain 
  range. 
  

  

  The 
  plan 
  proposed 
  in 
  our 
  First 
  Eeport 
  of 
  stationing 
  a 
  corps 
  of 
  observers 
  

   connected 
  with 
  the 
  Signal 
  Service 
  Bureau 
  in 
  the 
  breeding 
  areas 
  of 
  the 
  

   Northwest 
  for 
  the 
  purpose 
  of 
  gathering 
  information 
  in 
  reference 
  to 
  the 
  

   extent 
  of 
  egg 
  deposits 
  and 
  numbers 
  hatching, 
  and 
  to 
  give 
  notice 
  of 
  these 
  

   facts 
  and 
  the 
  departure 
  of 
  swarms, 
  we 
  think 
  not 
  only 
  entirely 
  feasible, 
  

   but 
  important, 
  and 
  one 
  that 
  would 
  be 
  of 
  immense 
  value 
  in 
  locust 
  years 
  

   to 
  the 
  sections 
  the 
  swarms 
  from 
  this 
  region 
  are 
  in 
  the 
  habit 
  of 
  visiting* 
  

  

  Second. 
  As 
  to 
  the 
  Temporary 
  Region, 
  

  

  What 
  has 
  been 
  stated 
  in 
  the 
  previous 
  part 
  of 
  this 
  chapter 
  in 
  refer- 
  

   ence 
  to 
  the 
  probable 
  effect 
  of 
  the 
  settlement 
  of 
  the 
  belt 
  in 
  Montana 
  on 
  

   the 
  locust 
  problem 
  in 
  its 
  relation 
  to 
  this 
  region 
  need 
  not 
  be 
  repeated 
  

   here. 
  As 
  the 
  relation 
  of 
  the 
  locust 
  problem 
  to 
  agriculture 
  in 
  the 
  tem- 
  

   porary 
  region 
  has 
  already 
  been 
  discussed 
  in 
  our 
  First 
  Eeport, 
  and 
  as 
  the 
  

   chief 
  objects 
  we 
  had 
  in 
  view 
  in 
  devoting 
  a 
  chapter 
  to 
  the 
  general 
  sub- 
  

   ject 
  in 
  this 
  report 
  were 
  to 
  consider 
  the 
  feasibility 
  of 
  the 
  plan 
  for 
  de- 
  

   stroying 
  the 
  locusts 
  by 
  burning 
  over 
  the 
  grassy 
  areas 
  of 
  the 
  permanent 
  

   region 
  and 
  to 
  present 
  the 
  scheme 
  herein 
  mentioned, 
  we 
  do 
  not 
  design 
  

   to 
  enter 
  at 
  present 
  into 
  an 
  extended 
  discussion 
  of 
  this 
  second 
  division 
  

   of 
  the 
  subject. 
  

  

  The 
  experience 
  of 
  the 
  farmers 
  of 
  this 
  section 
  in 
  fighting 
  the 
  young 
  

   locusts, 
  a 
  more 
  thorough 
  knowledge 
  of 
  their 
  history 
  and 
  habits 
  obtained 
  

   through 
  the 
  work 
  of 
  the 
  commission, 
  the 
  complete 
  fulfillment 
  of 
  the 
  pre- 
  

   dictions 
  of 
  the 
  commission 
  that 
  1877 
  would 
  close 
  the 
  series 
  of 
  the 
  inva- 
  

   sion 
  which 
  had 
  continued 
  from 
  1874, 
  and 
  the 
  conclusive 
  proof 
  of 
  the 
  

   theory 
  advanced 
  by 
  the 
  commission 
  that 
  this 
  pest 
  could 
  not 
  remain 
  per- 
  

   manently 
  in 
  this 
  region, 
  have 
  served 
  to 
  dispel 
  the 
  terror 
  these 
  insects 
  

   once 
  inspired, 
  and 
  should 
  no 
  other 
  remedies 
  than 
  those 
  already 
  known
