﻿NEW 
  DEFINITION 
  OF 
  TEMPORARY 
  REGION.

  ever 
  be 
  discovered, 
  the 
  locusts 
  can 
  never 
  prevent 
  the 
  settlement 
  of 
  thia 
  

   section, 
  or 
  in 
  fact 
  of 
  any 
  other 
  portion 
  of 
  the 
  United 
  States. 
  This 
  part 
  of 
  the 
  

   problem, 
  at 
  least, 
  is 
  undoubtedly 
  solved. 
  That 
  invading 
  swarms 
  will 
  

   again 
  come 
  down 
  on 
  these 
  border 
  States 
  and 
  Territories 
  is 
  not 
  doubted 
  ; 
  

   that 
  almost 
  every 
  year, 
  in 
  fact, 
  a 
  limited 
  swarm 
  drops 
  down 
  here 
  and 
  

   there, 
  we 
  know 
  to 
  be 
  true 
  ; 
  and 
  that 
  some 
  loss 
  is 
  occasioned 
  to 
  some 
  few 
  

   farmers 
  here 
  and 
  there 
  is 
  also 
  true 
  ; 
  but 
  it 
  is 
  no 
  more 
  than 
  occurs 
  in 
  

   almost 
  every 
  part 
  of 
  the 
  Union. 
  Every 
  year 
  limited 
  areas 
  in 
  every 
  State 
  

   suffer 
  from 
  some 
  kind 
  of 
  insects 
  ; 
  in 
  one 
  it 
  is 
  the 
  locust, 
  in 
  another 
  the 
  

   potato-beetle, 
  in 
  another 
  the 
  cotton- 
  worm, 
  in 
  another 
  the 
  cabbage- 
  

   worm, 
  &c. 
  We 
  should 
  not 
  be 
  surprised, 
  if 
  the 
  coming 
  spring 
  and 
  sum- 
  

   mer 
  are 
  dry, 
  to 
  see 
  a 
  limited 
  invasion 
  of 
  the 
  temporary 
  region 
  this 
  year. 
  

   We 
  have 
  no 
  sufficient 
  data 
  on 
  which 
  to 
  base 
  a 
  decided 
  opinion, 
  nor 
  do 
  

   we 
  feel 
  warranted 
  in 
  saying 
  that 
  even 
  the 
  probabilities 
  lean 
  in 
  that 
  

   direction, 
  but 
  there 
  are 
  a 
  few 
  slight 
  indications, 
  chiefly 
  meteorological, 
  

   which 
  are 
  sufficient 
  to 
  prevent 
  us 
  from 
  asserting 
  that 
  there 
  is 
  no 
  danger 
  

   of 
  an 
  invasion 
  the 
  coming 
  summer. 
  

  

  As 
  heretofore 
  stated, 
  facts 
  gathered 
  during 
  the 
  last 
  two 
  years 
  have 
  

   forced 
  upon 
  us 
  the 
  conclusion 
  that 
  the 
  northeast 
  portion 
  of 
  Nebraska 
  

   and 
  the 
  eastern 
  part 
  of 
  Dakota 
  should 
  not 
  be 
  classed 
  in 
  the 
  temporary 
  

   region 
  in 
  the 
  same 
  sense 
  as 
  Western 
  Iowa, 
  Southern 
  Nebraska, 
  Kansas, 
  

   and 
  the 
  regions 
  southward 
  ; 
  but 
  that 
  they 
  really 
  belong 
  to 
  what 
  may 
  

   truly 
  be 
  termed 
  the 
  subpermanent 
  region. 
  Even 
  the 
  extreme 
  western 
  

   part 
  of 
  Minnesota 
  appears 
  to 
  fall 
  into 
  the 
  same 
  category. 
  In 
  this 
  region 
  

   the 
  species 
  appears 
  to 
  be 
  able 
  to 
  maintain 
  its 
  existence 
  for 
  a 
  longer 
  time 
  

   than 
  in 
  the 
  southern 
  section, 
  though 
  perhaps 
  the 
  former 
  region 
  is 
  no- 
  

   more 
  subject 
  to 
  the 
  invasions 
  of 
  the 
  great 
  hordes 
  than 
  the 
  latter. 
  The 
  

   area 
  to 
  which 
  this 
  statement 
  appears 
  to 
  be 
  particularly 
  applicable 
  

   is 
  that 
  which 
  lies 
  around 
  the 
  southern 
  and 
  western 
  side 
  of 
  the 
  Co- 
  

   teau 
  of 
  the 
  Prairies. 
  The 
  elevated 
  plateau 
  is 
  perhaps 
  one 
  cause 
  of 
  this^ 
  

   But 
  the 
  data 
  we 
  have 
  obtained 
  are 
  not 
  sufficient 
  to 
  enable 
  us 
  to 
  decide 
  

   this 
  point 
  with 
  certainty. 
  * 
  

  

  If 
  the 
  proposition 
  of 
  the 
  Commissioner 
  of 
  Agriculture 
  to 
  cover 
  this- 
  

   with 
  trees 
  could 
  be 
  carried 
  out, 
  it 
  would 
  most 
  certainly 
  have 
  an 
  ameli- 
  

   orating 
  effect 
  j 
  but 
  without 
  any 
  means 
  of 
  irrigating 
  them, 
  we 
  have 
  some 
  

   doubt 
  as 
  to 
  whether 
  they 
  could 
  be 
  made 
  to 
  live 
  and 
  grow. 
  If 
  any 
  

   species 
  can 
  be 
  found 
  that 
  will 
  live 
  without 
  irrigation, 
  the 
  plan 
  is 
  most 
  

   certainly 
  a 
  good 
  one 
  and 
  would 
  justify 
  the 
  government 
  in 
  undertaking 
  

   it. 
  A 
  belt 
  of 
  timber 
  along 
  the 
  Mobrara, 
  which, 
  within 
  historic 
  times, 
  

   was 
  a 
  wooded 
  stream, 
  would 
  also 
  be 
  beneficial 
  to 
  a 
  limited 
  extent. 
  But 
  

   to 
  materially 
  modify 
  the 
  locust 
  injuries 
  by 
  this 
  means 
  would 
  require 
  

   a 
  broad 
  forest 
  belt 
  of 
  a 
  hundred 
  miles 
  or 
  more 
  in 
  width, 
  stretching 
  

   from 
  Big 
  Sioux 
  to 
  the 
  vicinity 
  of 
  the 
  Black 
  Hills. 
  If 
  the 
  locusts 
  sweep 
  

   over 
  mountains 
  covered 
  with 
  forests, 
  as 
  we 
  know 
  is 
  a 
  fact 
  often 
  wit- 
  

   nessed 
  in 
  Colorado, 
  a 
  narrow 
  belt 
  of 
  timber 
  along 
  the 
  line 
  of 
  their 
  march 
  

  

  *Note. 
  — 
  Recent 
  investigations 
  strongly 
  confirm 
  this 
  opinion.
