  Catching 
  the 
  moths 
  with 
  ingeniously-contrived 
  traps, 
  

   poisoning 
  them 
  with 
  sweetened 
  cobalt 
  dropped 
  into 
  the 
  

   bloom 
  of 
  the 
  Jamestown 
  weed, 
  or 
  killing 
  them 
  with 
  pad- 
  

   dles 
  as 
  they 
  hover 
  about 
  the 
  tobacco 
  plants 
  after 
  sunset, 
  are 
  

   all 
  practiced. 
  Recently, 
  as 
  in 
  Tennessee, 
  porcelain 
  imita- 
  

   tions 
  of 
  the 
  blossom 
  of 
  the 
  Jamestown 
  weed 
  have 
  been 
  in- 
  

   troduced. 
  These 
  are 
  fastened 
  upon 
  sticks, 
  set 
  up 
  at 
  short 
  

   distances 
  apart 
  throughout 
  the 
  tobacco 
  field, 
  and 
  are 
  supplied 
  

   wath 
  a 
  few 
  drops 
  of 
  poisoned 
  sirup. 
  They 
  are 
  cheap, 
  will 
  

   last 
  with 
  ordinary 
  care 
  a 
  lifetime, 
  and 
  are 
  highly 
  recom- 
  

   mended 
  by 
  planters 
  who 
  have 
  used 
  them. 
  A 
  knowledge 
  of 
  

   the 
  transformations 
  of 
  these 
  insects 
  will 
  enable 
  the 
  obser- 
  

   vant 
  farmer 
  to 
  do 
  much 
  to 
  reduce 
  their 
  numbers, 
  and 
  if 
  it 
  

   were 
  possible 
  to 
  secure 
  prompt 
  measures 
  throughout 
  a 
  con- 
  

   siderable 
  section 
  of 
  country, 
  or 
  even 
  by 
  the 
  growers 
  of 
  a 
  

   large 
  neighborhood, 
  much 
  disagreeable 
  labor 
  might 
  be 
  

   saved. 
  

  

  The 
  moth 
  deposits 
  an 
  egg 
  of 
  a 
  sea-green 
  color, 
  not 
  larger 
  

   than 
  a 
  mustard 
  seed, 
  upon 
  the 
  surface 
  of 
  the 
  leaf. 
  This 
  

   egg 
  gradually 
  assumes 
  a 
  cream 
  color, 
  and 
  from 
  it, 
  in 
  due 
  

   time, 
  a 
  tiny 
  worm 
  issues, 
  not 
  larger 
  than 
  a 
  horse 
  hair, 
  and 
  

   about 
  one-eighth 
  of 
  an 
  inch 
  in 
  length. 
  The 
  process 
  of 
  

   hatching 
  embraces 
  from 
  twenty-four 
  to 
  thirty-six 
  hours, 
  de- 
  

   pending 
  upon 
  tiie 
  condition 
  of 
  the 
  weather. 
  The 
  worm 
  

   begins 
  to 
  eat 
  immediately, 
  making 
  first 
  a 
  small 
  hole 
  in 
  the 
  

   leaf, 
  through 
  which 
  it 
  passes 
  in 
  iiot 
  weather 
  to 
  the 
  under 
  

   side, 
  and 
  occasionally 
  the 
  eggs 
  are 
  there 
  deposited 
  by 
  the 
  

   moth. 
  This 
  worm, 
  though 
  voracious, 
  does 
  little 
  damage 
  for 
  

   four 
  or 
  five 
  days. 
  Its 
  power 
  of 
  destruction 
  increases 
  ex- 
  

   ceedingly 
  with 
  each 
  day, 
  and 
  this 
  makes 
  it 
  highly 
  ipipor- 
  

   tant 
  to 
  go 
  over 
  the 
  field 
  often 
  in 
  search 
  of 
  them. 
  

  

  When 
  the 
  horn-worm 
  has 
  attained 
  full 
  size 
  it 
  stops 
  eating, 
  

   comes 
  down 
  from 
  the 
  plant, 
  and 
  usually 
  burrows 
  into 
  the 
  

   ground 
  close 
  to 
  its 
  last 
  feeding 
  place, 
  but 
  not 
  unfrequently 
  

   crawls 
  away 
  some 
  distance 
  to 
  find 
  soil 
  suQiciently 
  soft 
  to 
  

   enable 
  it 
  to 
  get 
  some 
  inches 
  below 
  the 
  surface. 
  Here 
  it 
  

   becomes 
  quiescent, 
  casts 
  ofi" 
  its 
  larva 
  skin, 
  and 
  asuimes 
  its 
  

   pupal 
  form. 
  It 
  is 
  now 
  oval 
  in 
  shape, 
  four 
  times 
  as 
  long 
  as 
  

   it 
  is 
  thick, 
  about 
  1^ 
  inches 
  in 
  length, 
  and 
  the 
  iiard, 
  glossy 
  

   envelope 
  is 
  of 
  a 
  bright 
  chestnut 
  color. 
  The 
  forward 
  end 
  is 
  

   prolonged 
  into 
  a 
  long, 
  tube-like 
  appendage, 
  bent 
  backward 
  

   and 
  firmly 
  attached 
  to 
  the 
  chest, 
  forming 
  a 
  loop 
  like 
  a 
  

   pitcher-handle, 
  this 
  tube 
  ensheathing 
  the 
  tongue, 
  which 
  is
