  is 
  not 
  likely 
  to 
  stop 
  their 
  progress; 
  but 
  if 
  the 
  Coteau 
  of 
  the 
  Erairies 
  is 
  

   really 
  a 
  permanent 
  breeding 
  ground, 
  which 
  we 
  are 
  not 
  yet 
  fully 
  pre- 
  

   pared 
  to 
  affirm, 
  clothing 
  it 
  with 
  a 
  forest 
  growth 
  would 
  have 
  a 
  tendency 
  

   to 
  prevent 
  them 
  from 
  using 
  it 
  for 
  this 
  purpose. 
  

  

  We 
  are 
  inclined 
  to 
  believe 
  that, 
  aside 
  from 
  the 
  improved 
  means 
  of 
  

   •destroying 
  the 
  young, 
  and 
  a 
  system 
  of 
  farming 
  least 
  liable 
  to 
  suffer 
  in- 
  

   jury 
  from 
  the 
  invading 
  swarms, 
  the 
  chief 
  hope 
  of 
  amelioration 
  lies 
  in 
  

   the 
  increase 
  of 
  the 
  agricultural 
  population 
  and 
  its 
  gradual 
  extension 
  

   into 
  Dakota. 
  The 
  railroads 
  which 
  are 
  now 
  pushing, 
  their 
  way 
  into 
  this 
  

   section, 
  especially 
  those 
  leading 
  into 
  Southern 
  Dakota, 
  will 
  aid 
  greatly 
  

   in 
  bringing 
  about 
  this 
  result. 
  With 
  the 
  increase 
  of 
  population 
  the 
  de- 
  

   struction 
  of 
  the 
  young 
  and 
  of 
  eggs 
  will 
  become 
  more 
  and 
  more 
  effectual. 
  

  

  As 
  Minnesota 
  is 
  well 
  supplied 
  with 
  lakes 
  and 
  the 
  supply 
  of 
  moisture 
  

   ample, 
  it 
  is 
  more 
  than 
  probable 
  that 
  it 
  would 
  be 
  a 
  wise 
  policy 
  for 
  the 
  

   farmers 
  of 
  the 
  southwestern 
  portion 
  and 
  also 
  of 
  the 
  extreme 
  southeast- 
  

   ern 
  part 
  of 
  Dakota 
  to 
  devote 
  their 
  lands 
  and 
  attention 
  largely 
  to 
  graz- 
  

   ing 
  of 
  cattle 
  and 
  sheep. 
  This 
  industry, 
  as 
  has 
  been 
  shown 
  in 
  our 
  First 
  

   Report, 
  is 
  not 
  liable 
  to 
  the 
  same 
  injury 
  from 
  the 
  locusts 
  as 
  are 
  the 
  grain 
  

   <crops. 
  But 
  it 
  is 
  not 
  likely 
  this 
  will 
  be 
  adopted 
  to 
  any 
  considerable 
  ex- 
  

   tent 
  until 
  the 
  virgin 
  freshness 
  and 
  strength 
  of 
  the 
  soil 
  is 
  weakened 
  by 
  

   repeated 
  wheat 
  crops 
  or 
  wheat 
  raising 
  ceases 
  from 
  some 
  cause 
  to 
  be 
  

   remunerative. 
  This 
  State 
  is 
  well 
  adapted 
  to 
  its 
  production, 
  and 
  it 
  is 
  

   not 
  only 
  the 
  most 
  profitable 
  crop 
  at 
  present, 
  but 
  is 
  the 
  money 
  crop. 
  

   The 
  raising 
  of 
  wheat 
  will, 
  therefore, 
  go 
  on 
  until 
  it 
  ceases 
  to 
  be 
  as 
  profit- 
  

   able 
  as 
  it 
  is 
  now, 
  in 
  spite 
  of 
  locust 
  raids 
  and 
  grasshopper 
  devastations. 
  

  

  We 
  may 
  repeat, 
  therefore, 
  in 
  reference 
  to 
  the 
  whole 
  of 
  the 
  temporary 
  

   region, 
  that 
  the 
  " 
  grasshopper 
  scare" 
  is 
  over 
  and 
  past; 
  the 
  tide 
  of 
  immi- 
  

   gration 
  thither 
  is 
  greater 
  than 
  ever 
  before, 
  and 
  those 
  who 
  go 
  now, 
  go 
  

   with 
  their 
  eyes 
  fully 
  opened 
  to 
  the 
  difficulties 
  with 
  which 
  they 
  have 
  to 
  

   contend, 
  so 
  far 
  as 
  the 
  locusts 
  are 
  concerned, 
  and 
  hence 
  will 
  not 
  be 
  driven 
  

   back 
  by 
  this 
  cause. 
  Year 
  by 
  year, 
  as 
  the 
  population 
  increases, 
  the 
  

   power 
  to 
  contend 
  with 
  this 
  evil 
  increases. 
  The 
  cultivation 
  of 
  the 
  soil, 
  

   the 
  planting 
  of 
  trees, 
  the 
  introduction 
  of 
  stock, 
  such 
  as 
  hogs, 
  the 
  in- 
  

   crease 
  in 
  domestic 
  fowls, 
  and 
  the 
  improvement 
  in 
  the 
  means 
  of 
  destroy- 
  

   ing 
  the 
  young, 
  bring 
  the 
  evil 
  more 
  and 
  more 
  under 
  control. 
  There 
  is, 
  

   therefore, 
  good 
  reason 
  for 
  believing 
  that 
  the 
  day 
  is 
  not 
  far 
  distant 
  when 
  

   the 
  locust 
  will 
  be 
  looked 
  upon 
  as 
  no 
  more 
  injurious 
  than 
  the 
  chinch-bug 
  

   or 
  cotton-worm, 
  or 
  perhaps 
  as 
  even 
  less 
  so. 
  

  

  The 
  work 
  of 
  the 
  Commission, 
  therefore, 
  so 
  far 
  as 
  it 
  relates 
  to 
  the 
  locust 
  

   in 
  the 
  temporary 
  region, 
  may 
  be 
  considered 
  as 
  about 
  completed. 
  The 
  

   great 
  point 
  left 
  lor 
  us 
  to 
  determine 
  is 
  that 
  which 
  is 
  chiefly 
  discussed 
  in 
  

   the 
  present 
  report 
  : 
  Is 
  it 
  possible 
  to 
  exterminate 
  the 
  locusts 
  in 
  their 
  

   native 
  breeding 
  grounds 
  ? 
  If 
  not, 
  how 
  far 
  and 
  by 
  what 
  means 
  is 
  it 
  pos- 
  

   sible 
  so 
  to 
  diminish 
  their 
  numbers 
  as 
  to 
  render 
  the 
  migrating 
  swarms 
  

   comparatively 
  innoxious 
  ? 
  

  

  General 
  remarks.

  many
