  — 
  Picking 
  the 
  caterpillars 
  off 
  the 
  plants 
  by 
  hand, 
  ditching, 
  

   and 
  the 
  use 
  of 
  burning 
  straw 
  when 
  the 
  caterj)illars 
  migrate 
  from 
  one 
  

   field 
  to 
  another, 
  are 
  remedies 
  that 
  can 
  be 
  applied 
  in 
  the 
  cotton 
  States, 
  

   when 
  labor 
  is 
  cheap, 
  to 
  good 
  advantage. 
  By 
  these 
  means, 
  and 
  the 
  use 
  \ 
  

   of 
  Paris 
  green, 
  the 
  evil 
  can 
  be 
  stamped 
  out, 
  provided 
  co-operation 
  is 
  

   practised 
  among 
  adjoining 
  plantations. 
  The 
  same 
  means 
  should 
  be 
  

   used 
  as 
  with 
  the 
  northern 
  army- 
  worm 
  and 
  potato-beetle. 
  The 
  most 
  

   serviceable 
  remedy 
  has 
  been 
  the 
  use 
  of 
  Pans 
  green, 
  either 
  dry, 
  mixed 
  

   with 
  cheap 
  flour, 
  or 
  in 
  water, 
  in 
  proportions 
  sufficient 
  to 
  kill 
  the 
  cater- 
  

   pillars 
  without 
  injuring 
  the 
  plants. 
  This 
  remedy 
  has 
  been 
  successfully 
  

   tried 
  in 
  the 
  South. 
  I 
  take 
  the 
  following 
  modes 
  of 
  using 
  this 
  poison 
  

   from 
  Mr. 
  Eiley's 
  Sixth 
  Eeport. 
  In 
  Texas, 
  by 
  the 
  use 
  of 
  Paris 
  green 
  

   mixed 
  with 
  lime 
  or 
  plaster, 
  or 
  even 
  fine 
  sand, 
  "a 
  neighbor 
  has 
  picked 
  

   already 
  10 
  bales 
  of 
  500 
  pounds 
  each 
  from 
  13 
  acres, 
  while 
  freedmen 
  on 
  

   the 
  same 
  farm 
  lost 
  their 
  whole 
  crop 
  by 
  refusing 
  to 
  use 
  it." 
  Eepeated 
  

   applications 
  should 
  be 
  made 
  after 
  the 
  appearance 
  of 
  successive 
  broods 
  

   of 
  worms. 
  By 
  some, 
  it 
  is 
  said 
  application 
  should 
  not 
  be 
  made 
  after 
  the 
  

   bolls 
  are 
  open, 
  lest 
  it 
  become 
  dangerous 
  to 
  picker 
  and 
  giuner." 
  Mr. 
  J. 
  

   E. 
  Maxwell, 
  of 
  Alabama, 
  writes 
  to 
  the 
  Southern 
  Farmer: 
  "I 
  have 
  been 
  

   successful 
  in 
  the 
  use 
  of 
  Paris 
  green 
  on 
  the 
  cotton- 
  worm. 
  I 
  had 
  100 
  

   acres 
  of 
  cotton 
  on 
  swamp-land 
  that 
  would 
  have 
  been 
  ruined, 
  but 
  on 
  

   their 
  first 
  appearance 
  I 
  commenced 
  on 
  them. 
  I 
  put 
  eight 
  hands 
  on 
  

   mules, 
  with 
  two-gallon 
  watering-pots, 
  and 
  had 
  ten 
  more 
  hands 
  and 
  two 
  

   wagons 
  engaged 
  in 
  keeping 
  them 
  supplied 
  with 
  water 
  and 
  poison, 
  and 
  

   "went 
  over 
  my 
  cotton 
  twice, 
  up 
  one 
  side 
  of 
  a 
  row 
  and 
  down 
  the 
  other, 
  

   going 
  thus 
  twice 
  to 
  each 
  row. 
  Poison, 
  labor, 
  and 
  all 
  cost 
  me 
  about 
  

   $300. 
  It 
  has 
  saved 
  me 
  at 
  the 
  very 
  least 
  20 
  bales 
  of 
  cotton. 
  I 
  used 
  the 
  

   poison 
  by 
  putting 
  to 
  each 
  canful 
  of 
  water 
  half 
  a 
  table-spoonful 
  of 
  poi- 
  

   son 
  and 
  three 
  table- 
  spoonfuls 
  of 
  flour, 
  stirring 
  it 
  well. 
  I 
  tried 
  it 
  first 
  

   without 
  flour, 
  but 
  every 
  shower 
  would 
  wash 
  all 
  the 
  poison 
  off." 
  Another 
  

   Alabama 
  farmer 
  successfully 
  used 
  the 
  powder-mixture 
  on 
  50 
  acres 
  at 
  a 
  

   cost 
  of 
  68 
  cents 
  an 
  acre. 
  Mr. 
  D. 
  F. 
  Prout 
  says 
  that 
  the 
  cost 
  of 
  material 
  

   an 
  acre 
  "for 
  two 
  applications 
  will 
  not 
  exceed 
  81.75, 
  viz: 
  40 
  pounds 
  of 
  

   flour, 
  at 
  2J 
  cents 
  per 
  pound, 
  and 
  2 
  pounds 
  of 
  Paris 
  green, 
  at 
  37J 
  cents." 
  

   He 
  found, 
  in 
  his 
  own 
  experience, 
  that 
  an 
  expenditure 
  of 
  $100 
  on 
  about 
  

   80 
  acres 
  increased 
  the 
  crop 
  at 
  least 
  10 
  bales. 
  

  

  The 
  Boll- 
  Worm, 
  HeleoiMs 
  armigera 
  Linn. 
  — 
  Eating 
  the 
  boll 
  of 
  the 
  cotton-plant, 
  

   corn 
  in 
  the 
  ear, 
  tomato-fruit, 
  etc. 
  ; 
  a 
  rather 
  large, 
  thick-boclied, 
  pale-green 
  or 
  dark- 
  

   brown 
  caterpillar, 
  with 
  longitudinal 
  light 
  and 
  dark 
  lines, 
  and 
  with 
  a 
  broad 
  yellow 
  

   band 
  below 
  the 
  breathing-pores, 
  and 
  marked 
  with 
  black 
  spots, 
  from 
  which 
  arise 
  fine 
  

   hairs. 
  

  

  This 
  moth 
  is 
  a 
  cosmopolitan, 
  being 
  injurious 
  in 
  Europe, 
  and 
  inhab- 
  

   iting 
  Japan 
  and 
  even 
  Australia. 
  It 
  feeds 
  on 
  a 
  variety 
  of 
  plants, 
  not 
  

   a 
  ^.^ppp-,.^^.-,,.,,,^ 
  only 
  devouring 
  the 
  calyx 
  of 
  the 
  flower 
  

  

  as 
  the 
  stock, 
  unripe 
  and 
  ripe 
  tomates, 
  

   green 
  pease, 
  string-beans, 
  and 
  young 
  

   pumpkins. 
  It 
  bores 
  into 
  the 
  stalks 
  of 
  

   the 
  gladiolus, 
  and 
  in 
  Europe 
  is 
  known 
  to 
  

   devour 
  the 
  heads 
  of 
  hemp 
  and 
  leaves 
  of 
  

   tobacco 
  and 
  of 
  lucern, 
  as 
  well 
  as 
  chick 
  

   or 
  coffee 
  pea.
