  wine 
  lees 
  were 
  not 
  required. 
  The 
  solution, 
  however, 
  was 
  more 
  speedily 
  

   exhausted 
  owing 
  to 
  the 
  quick 
  fermentation 
  and 
  the 
  swinging 
  of 
  the 
  

   apparatus 
  in 
  the 
  wind. 
  It 
  would 
  be 
  worth 
  while 
  trying 
  earthenware 
  

   bottles 
  and 
  the 
  fixing 
  of 
  the 
  trap 
  by 
  binding 
  it 
  to 
  the 
  vine 
  stake. 
  

  

  Heavy 
  rain 
  plays 
  havoc 
  with 
  the 
  traps 
  by 
  overfilling 
  them, 
  the 
  moths 
  

   already 
  captured 
  being 
  thus 
  released, 
  and 
  further 
  the 
  dilution 
  and 
  

   cooUng 
  of 
  the 
  liquid 
  renders 
  the 
  traps 
  useless 
  when 
  the 
  moths 
  resume 
  

   flight 
  after 
  the 
  rain. 
  The 
  authors 
  remedied 
  this 
  by 
  adopting 
  covers 
  

   (either 
  strips 
  of 
  tarred 
  millboard, 
  cut 
  and 
  bent 
  so 
  as 
  to 
  produce 
  a 
  

   circular, 
  sfightly 
  conical 
  roof, 
  or 
  earthenware 
  saucers 
  used 
  upside 
  down) 
  

   suspended 
  at 
  a 
  height 
  of 
  6 
  to 
  8 
  inches 
  above 
  the 
  pots 
  on 
  the 
  wires 
  by 
  

   which 
  the 
  latter 
  hang. 
  This 
  system 
  proved 
  a 
  great 
  success, 
  the 
  

   number 
  of 
  moths 
  captured 
  being 
  much 
  greater 
  than 
  that 
  in 
  the 
  un- 
  

   covered 
  pots. 
  This 
  was 
  very 
  marked 
  in 
  rainy 
  weather 
  or 
  when 
  the 
  

   north 
  or 
  north-east 
  winds 
  were 
  blowing, 
  which 
  are 
  unfavourable 
  to 
  

   flight. 
  The 
  system 
  has 
  no 
  disadvantages, 
  it 
  effects 
  economy 
  in 
  liquid 
  

   and 
  makes 
  for 
  regularity 
  and 
  success 
  in 
  the 
  catches. 
  The 
  authors 
  

   specially 
  insist 
  on 
  the 
  necessity 
  for 
  the 
  trapping 
  to 
  cease 
  as 
  soon 
  as 
  

   most 
  of 
  the 
  eggs 
  have 
  been 
  laid 
  and 
  long 
  before 
  the 
  flight 
  has 
  come 
  

   to 
  an 
  end. 
  Otherwise 
  many 
  very 
  useful 
  insects 
  are 
  taken. 
  In 
  one 
  

   case 
  they 
  found 
  628 
  Chrysopids 
  captured 
  after 
  the 
  traps 
  had 
  ceased 
  

   to 
  attract 
  Polychrosis. 
  These 
  Chrysopids 
  and 
  their 
  progeny 
  could 
  

   have 
  destroyed 
  about 
  235,000 
  Polychrosis 
  caterpillars 
  in 
  August 
  and 
  

   September. 
  The 
  only 
  efficacious 
  method 
  of 
  preventing 
  this 
  trouble 
  

   is 
  to 
  reverse 
  the 
  pots 
  when 
  they 
  have 
  served 
  their 
  purpose. 
  The 
  

   same 
  arrangement 
  of 
  wires 
  used 
  to 
  hang 
  them 
  can 
  be 
  used 
  without 
  

   any 
  adjustment 
  and 
  is 
  practically 
  permanent.

  may 
  be 
  said 
  of

  Ocypus

  that

   Ploughing

  the

  April 
  or 
  early 
  in 
  May

  not 
  efficacious, 
  though 
  

   poultry 
  following 
  the 
  plough 
  might 
  destroy 
  the

  pupae 
  

   exposed

  be 
  intercalated,

  are 
  very 
  fond
