  To 
  protect 
  garden 
  beds 
  from 
  mole-crickets, 
  they 
  may 
  be 
  enclosed 
  

   with 
  4-inch 
  boards, 
  haK-buried, 
  with 
  gaps 
  at 
  intervals, 
  in 
  which 
  pots, 
  

   6 
  to 
  8 
  inches 
  in 
  diameter, 
  are 
  sunk 
  level 
  with 
  the 
  soil. 
  These 
  mav 
  be 
  

   empty 
  or 
  filled 
  with 
  water 
  or 
  flour. 
  To 
  keep 
  these 
  pests 
  away 
  from 
  

   pot 
  beds, 
  cHnkers 
  should 
  be 
  spread 
  round 
  or 
  beneath 
  them. 
  The 
  

   presence 
  of 
  a 
  nest 
  is 
  usually 
  indicated 
  by 
  a 
  small 
  mound 
  of 
  worked 
  

   earth, 
  beneath 
  which 
  it 
  will 
  be 
  found 
  at 
  a 
  depth 
  of 
  about 
  6 
  inches. 
  

   The 
  galleries 
  may 
  be 
  flooded, 
  or 
  soapy 
  water, 
  petroleum, 
  carbon 
  

   bisulphide, 
  etc., 
  poured 
  into 
  them. 
  Before 
  making 
  sowings 
  in 
  infested 
  

   beds, 
  they 
  may 
  be 
  covered 
  with 
  cooked 
  grains 
  of 
  maize, 
  sprinkled 
  

   with 
  arsenious 
  acid 
  and 
  raked 
  over 
  with 
  earth. 
  Napthalene 
  crystals 
  

   drive 
  away 
  mole-crickets, 
  but 
  do 
  not 
  kill 
  them. 
  The 
  author 
  also 
  

   mentions 
  traps 
  [see 
  this 
  Review, 
  Ser. 
  A, 
  i, 
  p. 
  496] 
  and 
  insists 
  that 
  no 
  

   method 
  is 
  really 
  efficient 
  unless 
  continuously 
  persevered 
  in, 
  when 
  

   success 
  should 
  be 
  attained 
  in 
  two 
  or 
  three 
  years.

  The 
  author 
  is 
  informed 
  that 
  absolutely 
  conclusive 
  tests 
  against 
  

   Phylloxera 
  have 
  been 
  made 
  with 
  a 
  special 
  product, 
  a 
  sample 
  of 
  which 
  

   has 
  been 
  given 
  to 
  him 
  by 
  the 
  inventor. 
  The 
  procedure 
  is 
  exceedingly 
  

   simple. 
  A 
  hollow 
  is 
  made 
  round 
  the 
  stock 
  and 
  the 
  substance 
  placed 
  

   therein. 
  As 
  much 
  water 
  as 
  possible 
  is 
  poured 
  in 
  so 
  as 
  to 
  soak 
  the 
  soil 
  

   around 
  the 
  roots 
  with 
  the 
  active 
  principles 
  contained 
  in 
  the 
  remedy. 
  

   It 
  is 
  said 
  that 
  dying 
  vines 
  which 
  were 
  thus 
  treated 
  recovered 
  their 
  

   vigour 
  in 
  two 
  years, 
  and 
  that 
  vines 
  treated 
  about 
  eight 
  years 
  ago 
  

   may 
  be 
  seen 
  flourishing 
  in 
  the 
  midst 
  of 
  re-planted 
  vines. 
  The 
  cost 
  

   is 
  said 
  to 
  be 
  about 
  5d. 
  or 
  6d. 
  per 
  vine. 
  The 
  author 
  is 
  about 
  to 
  make 
  

   some 
  tests 
  himself. 
  The 
  disadvantages 
  of 
  carbon 
  bisulphide 
  do 
  not 
  

   occur 
  with 
  this 
  remedy, 
  which 
  appears 
  to 
  confer 
  a 
  lasting 
  immunity 
  

   from 
  infestation.

  The 
  author 
  states 
  that 
  hedges 
  planted 
  for 
  bird 
  protection 
  will 
  not 
  

   prove 
  a 
  danger 
  to 
  fruit-growing 
  even 
  if 
  composed

  plants 
  attractive 
  

   to

  The

  will 
  always 
  be 
  sufficiently 
  controlled 
  

   by

  and
