  cling 
  the 
  twig, 
  binding 
  the 
  leaf 
  securely 
  to 
  it, 
  and 
  holding 
  it 
  there 
  during 
  

   the 
  falling 
  of 
  the 
  other 
  leaves 
  and 
  through 
  all 
  the 
  winter's 
  storms. 
  In- 
  

   close 
  the 
  cocoons 
  in 
  a 
  box 
  of 
  sufficient 
  size 
  to 
  admit 
  of 
  the 
  expansion 
  of 
  

   the 
  wings 
  of 
  the 
  moth 
  and 
  some 
  freedom 
  of 
  motion 
  when 
  it 
  comes 
  from 
  

   its 
  cocoon. 
  On 
  some 
  morning 
  in 
  the 
  month 
  of 
  June, 
  (earlier 
  if 
  they 
  have 
  

   been 
  kept 
  in 
  a 
  warm 
  apartment) 
  if 
  your 
  cocoons 
  contained 
  living 
  pupae, 
  

   you 
  will 
  find 
  that 
  the 
  moths 
  have 
  emerged, 
  and 
  deposited 
  a 
  large 
  number 
  

   of 
  eggs, 
  cementing 
  them 
  to 
  the 
  sides 
  of 
  the 
  box. 
  Note 
  the 
  regularity 
  of 
  

   form 
  and 
  size 
  of 
  the 
  eggs, 
  each 
  with 
  its 
  yellowish 
  spot 
  upon 
  its 
  somewhat 
  

   flattened 
  upper 
  side. 
  When 
  two 
  or 
  three 
  weeks 
  thereafter, 
  the 
  eggs 
  com- 
  

   mence 
  to 
  hatch, 
  with 
  a 
  magnifier 
  in 
  hand, 
  watch 
  the 
  enclosed 
  caterpillars 
  

   eating 
  their 
  way 
  out 
  of 
  the 
  shells, 
  always 
  at 
  one 
  side, 
  and 
  through 
  a 
  some- 
  

   what 
  oval 
  hole. 
  

  

  Transfer 
  them 
  carefully 
  to 
  some 
  tender 
  leaves 
  of 
  their 
  food-plant, 
  and 
  

   observe 
  their 
  social 
  habit 
  of 
  grouping 
  themselves 
  side 
  by 
  side 
  like 
  soldiers 
  

   on 
  parade, 
  and 
  their 
  manner 
  of 
  eating. 
  After 
  you 
  have 
  watched 
  them 
  

   for 
  a 
  week, 
  and 
  noticed 
  perhaps 
  with 
  fear 
  of 
  the 
  result 
  lest 
  it 
  should 
  be* 
  

   token 
  incipient 
  disease, 
  their 
  fasting 
  for 
  a 
  day 
  or 
  tvv^o, 
  you 
  will 
  find 
  them 
  

   materially 
  increased 
  in 
  size 
  and 
  in 
  a 
  new 
  dress 
  of 
  light 
  green 
  with 
  bands 
  

   of 
  yellow, 
  bordered 
  with 
  black, 
  and 
  rows 
  of 
  white-bristled 
  tubercles 
  stud- 
  

   ding 
  their 
  body. 
  This 
  is 
  their 
  first 
  molting, 
  or 
  casting 
  of 
  their 
  skin 
  to 
  

   admit 
  of 
  increased 
  growth. 
  Four 
  or 
  five 
  times 
  you 
  may 
  observe 
  a 
  

   similar 
  molting, 
  followed 
  each 
  time 
  by 
  a 
  new 
  and 
  more 
  beautiful 
  garni- 
  

   ture. 
  As 
  the 
  caterpillar 
  approaches 
  maturity 
  you 
  will 
  surely 
  be 
  com- 
  

   pelled 
  to 
  regard 
  it 
  as 
  a 
  beautiful 
  creature, 
  with 
  its 
  creamy 
  pruinescence, 
  

   its 
  bands 
  of 
  dark 
  blue 
  tubercles 
  on 
  each 
  ring, 
  its 
  four 
  rich 
  coral-red 
  horns 
  

   on 
  the 
  front 
  of 
  its 
  body 
  and 
  a 
  yellow 
  black-ringed 
  one 
  at 
  its 
  other 
  

   extremity. 
  Carefully 
  observe 
  the 
  row 
  of 
  spiracles 
  or 
  breathing 
  pores 
  

   upon 
  the 
  sides 
  of 
  the 
  body 
  through 
  which 
  the 
  air 
  is 
  admitted 
  to 
  the 
  tra- 
  

   cheal 
  vessels, 
  and 
  the 
  peculiar 
  structure 
  of 
  its 
  many-hooked 
  clasping 
  legs. 
  

   It 
  is 
  indeed 
  a 
  wonderful 
  creature, 
  — 
  not 
  ''a 
  worm" 
  as 
  ordinarily 
  stig- 
  

   matized, 
  but 
  a 
  being 
  which 
  its 
  Creator 
  has 
  dignified 
  with 
  the 
  possession 
  

   of 
  eight 
  times 
  the 
  number 
  of 
  muscles 
  that 
  are 
  to 
  be 
  found 
  in 
  the 
  human 
  

   body 
  ; 
  and 
  in 
  every 
  way 
  worthy 
  of 
  your 
  study 
  and 
  admiration. 
  When 
  

   through 
  your 
  watchful 
  care, 
  your 
  little 
  colony 
  have 
  attained 
  their 
  growth, 
  

   to 
  your 
  great 
  relief 
  from 
  providing 
  them 
  with 
  an 
  adequate 
  supply 
  ot 
  

   their 
  daily 
  food, 
  do 
  not 
  fail 
  to 
  have 
  your 
  eyes 
  upon 
  them 
  as 
  they 
  throw 
  

   out 
  the 
  first 
  threads 
  that 
  are 
  to 
  bend 
  the 
  leaf 
  in 
  shape 
  for 
  enfolding 
  their 
  

   cocoons, 
  preparatory 
  to 
  passing 
  to 
  their 
  pupation. 
  The 
  leaf 
  may 
  hardly 
  

   be 
  more 
  than 
  marked 
  as 
  the 
  chosen 
  one, 
  before 
  you 
  may 
  see 
  the 
  busy
