  York, 
  states 
  that 
  of 
  fifty 
  eggs 
  laid 
  by 
  the 
  parent 
  sav\'-fly5 
  only 
  four 
  or 
  

   live 
  hatched 
  out 
  the 
  currant-worm. 
  We 
  see, 
  then, 
  that 
  though 
  the 
  

   birds 
  apparently 
  destroy 
  none, 
  an 
  immense 
  number 
  are 
  carried 
  off, 
  even 
  

   before 
  they 
  have 
  a 
  chance 
  of 
  doing 
  any 
  mischief, 
  by 
  minute 
  insects 
  of 
  

   their 
  own 
  order. 
  

  

  One 
  of 
  the 
  best 
  remedies 
  next 
  to 
  picking 
  them 
  off 
  by 
  hand, 
  and 
  which 
  

   is 
  really 
  the 
  most 
  practicable 
  method 
  of 
  getting 
  rid 
  of 
  them, 
  is 
  to 
  dust 
  

   powdered 
  white 
  hellebore 
  over 
  the 
  bushes, 
  by 
  sprinkling 
  it 
  from 
  a 
  

   muslin 
  bag 
  tied 
  to 
  a 
  stick, 
  as 
  it 
  otherwise 
  excites 
  violent 
  sneezing. 
  

   Used 
  in 
  this 
  small 
  quantity 
  it 
  is 
  not 
  poisonous. 
  This 
  is 
  the 
  remedy 
  

   used 
  with 
  most 
  success 
  in 
  the 
  West, 
  and 
  recommended 
  by 
  Messrs. 
  

   Walsh 
  and 
  Eiley. 
  I 
  have 
  used 
  it 
  with 
  good 
  success 
  in 
  my 
  own 
  garden, 
  

   and 
  it 
  is 
  a 
  thorough 
  remedy 
  if 
  thoroughly 
  and 
  persistently 
  applied. 
  

   Dr. 
  W. 
  Mack, 
  of 
  Salem, 
  tells 
  me 
  that 
  he 
  has 
  used 
  a 
  solution, 
  consisting 
  

   of 
  a 
  pound 
  of 
  copperas 
  to 
  six 
  gallons 
  of 
  water, 
  with 
  much 
  success. 
  It 
  

   blackens 
  the 
  leaves, 
  but 
  does 
  not 
  injure 
  them 
  permanently. 
  

  

  Dr. 
  E. 
  Worcester, 
  of 
  Waltham, 
  according 
  to 
  the 
  Boston 
  Journal 
  of 
  

   Chemistry, 
  finds 
  that 
  this 
  worm 
  "may 
  be 
  fully 
  and 
  almost 
  immediately 
  

   destroyed 
  by 
  the 
  use 
  of 
  carbolate 
  of 
  lime. 
  The 
  doctor 
  tried 
  the 
  powder 
  

   in 
  many 
  instances 
  during 
  the 
  past 
  summer, 
  and 
  found 
  that 
  while 
  it 
  was 
  

   fully 
  as 
  effective 
  as 
  hellebore, 
  it 
  was 
  less 
  disagreeable, 
  less 
  costly, 
  and 
  

   perfectly 
  safe. 
  The 
  method 
  of 
  using 
  it 
  is 
  to 
  sprinkle 
  it 
  over 
  the 
  vines 
  

   as 
  soon 
  as 
  the 
  worm 
  makes 
  its 
  appearance, 
  bringing 
  it 
  well 
  in 
  contact 
  

   with 
  the 
  leaves, 
  and 
  soon 
  the 
  insect 
  is 
  destroyed. 
  It 
  will 
  need 
  but 
  two 
  

   or 
  three 
  applications, 
  and 
  the 
  work 
  is 
  done." 
  

  

  This 
  worm 
  attacks 
  the 
  gooseberry 
  as 
  well 
  as 
  the 
  currant, 
  though 
  in 
  

   Massachusetts 
  its 
  ravages 
  have 
  been 
  more 
  confined 
  to 
  the 
  latter 
  shrub. 
  

   As 
  a 
  preventive 
  measure 
  against 
  its 
  further 
  spread, 
  in 
  buying 
  or 
  

   transporting 
  gooseberry 
  and 
  currant 
  bushes, 
  Walsh 
  recommends 
  that 
  

   the 
  roots 
  be 
  carefully 
  cleaned 
  of 
  dirt, 
  so 
  that 
  the 
  cocoons 
  may 
  not 
  be 
  

   carried 
  from 
  one 
  garden 
  or 
  nursery 
  to 
  another.

   As 
  this 
  species 
  may 
  be 
  confounded 
  with 
  the 
  European 
  saw-fly, 
  though 
  

   belonging 
  to 
  a 
  different 
  genus 
  [Pristiphora), 
  the 
  following 
  brief 
  account 
  

   of 
  it 
  is 
  extracted 
  from 
  my 
  Guide 
  to

  This

   &, 
  female, 
  from 
  the 
  "American 
  

   Entomologist"; 
  P. 
  grossiilarice 
  of 
  

   Walsh) 
  "is 
  a 
  widely 
  diffused 
  spe- 
  

   cies 
  in 
  the 
  ISTorthern 
  and 
  Western 
  

   States, 
  and 
  injures 
  the 
  currant 
  

   and 
  gooseberry. 
  The 
  female 
  fly 
  

   is 
  shining 
  black, 
  while 
  the 
  head 
  

   is 
  dull 
  yellow, 
  and 
  the

  for 
  

   a 
  quarter 
  of 
  their

  The

  are 
  partly 
  hyaline, 
  with 
  black 
  

   veins, 
  a 
  honey-yellow 
  costa, 
  and 
  a 
  dusky 
  stigma, 
  edged 
  with 
  honey- 
  

   yellow. 
  The 
  male 
  differs 
  a 
  little 
  in 
  having 
  black 
  coxre. 
  Mr. 
  Walsh 
  

   states 
  that 
  the 
  larva 
  is 
  a 
  pale 
  grass-green 
  worm, 
  half 
  an 
  inch 
  long, 
  with 
  

   a 
  black 
  head, 
  which 
  becomes 
  green 
  after 
  the 
  last 
  molt, 
  but 
  with 
  a 
  

   lateral 
  brown 
  stripe

  with 
  the 
  opposite 
  one 
  on 
  the 
  top 
  of 
  the 
  

   head, 
  where 
  it 
  is 
  more

  less 
  confluent 
  ; 
  and 
  a 
  central 
  brown-black 
  

   Bpot 
  on 
  its

  of
