  In 
  Gironde, 
  few 
  moths 
  are 
  taken 
  in 
  

   May 
  owing 
  to 
  bad 
  weather 
  restricting 
  flight. 
  In 
  any 
  case 
  it 
  is 
  worth 
  

   while 
  to 
  try 
  to 
  catch 
  even 
  half 
  the 
  females 
  before 
  oviposition. 
  In 
  

   July, 
  catches 
  are 
  heavy, 
  but 
  the 
  period 
  of 
  flight 
  only 
  lasts 
  from 
  8 
  to 
  10 
  

   days. 
  During 
  this 
  time 
  a 
  large 
  number 
  of 
  the 
  females 
  caught 
  have 
  

   not 
  yet 
  oviposited. 
  In 
  Medoc, 
  few 
  vineyards

   May, 
  and 
  the 
  others 
  are 
  now 
  suffering 
  for 
  their 
  neghgence.

  The 
  author 
  discusses 
  neutral, 
  acid 
  and 
  alkahne 
  Burgundy 
  mixtures 
  

   and 
  their 
  effects 
  in 
  the 
  laboratory. 
  The 
  superiority 
  of 
  acid 
  sprays 
  

   is 
  considered 
  to 
  be 
  due 
  not 
  only 
  to 
  the 
  excess 
  of 
  free 
  copper 
  sulphate 
  

   which 
  they 
  contain, 
  but 
  also 
  to 
  the 
  presence, 
  both 
  in 
  the 
  precipitate 
  

   and 
  in 
  the 
  solution, 
  of 
  tetracupric 
  sulphate. 
  This 
  latter 
  salt 
  is 
  

   insoluble 
  in 
  water, 
  but 
  most 
  sensitive 
  to 
  the 
  solvent 
  properties 
  of 
  the 
  

   carbonic 
  acid 
  contained 
  in 
  the 
  atmosphere. 
  This 
  same 
  basic 
  sulphate 
  

   also 
  ensures 
  the 
  enhanced 
  keeping 
  quahties 
  of 
  acid 
  sprays. 
  Wetting 
  

   Burgundy 
  mixtures 
  should 
  be 
  of 
  the 
  acid 
  variety. 
  In 
  preparing 
  these 
  

   acid 
  sprays 
  the 
  dilute 
  solution 
  of 
  sodium 
  carbonate 
  should 
  be 
  slowly 
  

   poured 
  into 
  the 
  concentrated 
  solution 
  of 
  copper 
  sulphate, 
  the 
  latter 
  

   being 
  constantly 
  stirred 
  meanwhile. 
  The 
  dose 
  of 
  sodium 
  carbonate 
  

   (90 
  per 
  cent, 
  pure) 
  necessary 
  varies 
  between 
  llj 
  oz. 
  and 
  13 
  oz. 
  per 
  

   2 
  lb. 
  of 
  copper 
  sulphate, 
  and 
  if 
  these 
  quantities 
  be 
  dissolved 
  in 
  20 
  

   gallons 
  of 
  water, 
  an 
  acid 
  spray 
  containing 
  from 
  2 
  to 
  5 
  parts 
  per 
  thousand 
  

   of 
  free 
  copper 
  sulphate 
  will 
  result.

  The 
  fact 
  that 
  Capsid 
  bugs 
  do 
  serious 
  damage 
  to 
  apples 
  has 
  been 
  

   known 
  in 
  England 
  for 
  several 
  years, 
  but 
  the 
  question 
  as 
  to 
  which 
  of 
  

   various 
  species 
  is 
  the 
  real 
  offender 
  is 
  difficult 
  to 
  decide.
