  SO 
  that 
  if 
  there 
  are 
  still 
  infested 
  nuts, 
  the 
  grubs 
  can 
  not 
  leave 
  and 
  

   enter 
  the 
  ground 
  and 
  continue 
  their 
  attack 
  another 
  year. 
  A 
  more 
  

   thorough 
  treatment 
  would 
  be 
  to 
  subject 
  the 
  nuts 
  in 
  a 
  tight 
  room 
  or 
  

   box 
  to 
  the 
  fumes 
  of 
  carbon 
  bisulphide 
  for 
  about 
  twenty-four 
  hours, 
  

   using 
  one 
  pound 
  of 
  the 
  carbon 
  bisulphide 
  in 
  shallow 
  vessels 
  to 
  

   each 
  1,000 
  cubic 
  feet 
  of 
  space. 
  Fire 
  must 
  be 
  kept 
  away 
  from 
  this 
  

   chemical 
  as 
  its 
  fumes 
  are 
  inflammable 
  and 
  explosive. 
  The 
  nuts 
  will 
  not 
  

   be 
  injured 
  by 
  this 
  treatment. 
  

  

  Jarring 
  the 
  trees 
  has 
  been 
  found 
  very 
  effectual 
  with 
  the 
  plum 
  curculio^ 
  

   and 
  it 
  should 
  be 
  of 
  equal 
  value 
  against 
  these 
  weevils, 
  while 
  requiring, 
  

   fewer 
  repetitions, 
  owing 
  to 
  the 
  shorter 
  period 
  of 
  oviposition. 
  By 
  visiting 
  

   the 
  trees 
  each 
  morning 
  and 
  catching 
  the 
  weevils 
  as 
  they 
  fall 
  upon 
  a 
  

   broad 
  sheet 
  prepared 
  for 
  the 
  purpose, 
  for 
  the 
  short 
  space 
  of 
  a 
  week 
  or 
  

   two, 
  the 
  crop 
  would 
  be 
  comparatively 
  free 
  from 
  these 
  pests. 
  Oaks 
  and 
  

   wild 
  chestnuts 
  should 
  be 
  as 
  remote 
  from 
  the 
  cultivated 
  ones 
  as 
  possible, 
  

   that 
  they 
  may 
  not 
  serve 
  the 
  insects 
  for 
  breeding 
  purposes.
