  the 
  mixture 
  of 
  a 
  fungicide 
  and 
  insecticide 
  in 
  combined 
  application, 
  

   regard 
  must 
  be 
  paid 
  to 
  the 
  fact 
  that 
  in 
  mixing 
  more 
  or 
  less 
  of 
  a 
  chemical 
  

   change 
  usually 
  takes 
  place, 
  which 
  may 
  destroy 
  the 
  killing 
  value 
  of 
  the 
  

   spray. 
  The 
  original 
  substances 
  may 
  also 
  be 
  changed 
  so 
  as 
  to 
  liberate 
  

   some 
  material 
  injurious 
  to 
  the 
  foliage 
  and 
  fruit. 
  Such 
  is 
  apparently 
  

   the 
  case 
  when 
  lead 
  hydrogen 
  arsenate 
  is 
  mixed 
  with 
  lime-sulphur. 
  

   It 
  is 
  thought 
  that 
  the 
  injury 
  which 
  often 
  occurs 
  is 
  due 
  to 
  the 
  free 
  

   arsenic 
  said 
  to 
  be 
  liberated. 
  Sprays 
  that 
  can 
  be 
  successfully 
  mixed 
  

   at 
  the 
  present 
  time 
  are 
  : 
  Bordeaux 
  mixture 
  and 
  arsenate 
  of 
  lead, 
  

   arsenite 
  of 
  zinc 
  or 
  Paris 
  green 
  ; 
  lime-sulphur 
  and 
  arsenate 
  of 
  lead 
  or 
  

   arsenite 
  of 
  zinc 
  ; 
  lime-sulphur 
  and 
  tobacco 
  sprays 
  ; 
  arsenate 
  of 
  lead 
  

   or 
  arsenite 
  of 
  zinc 
  may 
  also 
  be 
  added 
  to 
  the 
  last 
  mixture 
  when 
  desirable 
  ; 
  

   iron 
  sulphate 
  may 
  be 
  mixed 
  with 
  arsenate 
  of 
  lead 
  and 
  "Black-Leaf 
  40," 
  

   alone 
  or 
  mixed 
  ; 
  atomic 
  sulphur 
  and 
  lead 
  arsenate 
  ; 
  home-boiled 
  

   lime-sulphur 
  and 
  arsenate 
  of 
  lead. 
  Other 
  mixtures 
  have 
  been 
  tried 
  

   and 
  some 
  are 
  worthy 
  of 
  trial, 
  but 
  it 
  is 
  not 
  advisable 
  yet 
  to 
  recommend 
  

   them 
  for 
  general 
  use. 
  The 
  fruit-grower 
  is 
  warned 
  against 
  using 
  spray 
  

   mixtures 
  which 
  have 
  not 
  been 
  thoroughly 
  tested.

  The 
  boll 
  weevil 
  advance 
  in 
  Alabama 
  for 
  1913 
  was 
  unexpectedly 
  

   interrupted 
  by 
  very 
  early 
  frosts, 
  which 
  occurred 
  almost 
  a 
  month 
  earlier 
  

   than 
  the 
  first 
  killing 
  frosts 
  usually 
  do. 
  Some 
  sheltered 
  localities 
  

   escaped 
  killing 
  temperatures, 
  and 
  as 
  usual 
  the 
  greatest 
  advanc3 
  occurred 
  

   along 
  the 
  southern 
  edge 
  of 
  the 
  State. 
  The 
  author 
  remarks 
  that 
  it 
  was 
  

   doubtless 
  only 
  the 
  early 
  hard 
  frost 
  which 
  stopped 
  the 
  boll 
  weevil 
  

   entering 
  Georgia 
  this 
  year, 
  and 
  it 
  is 
  sure 
  to 
  have 
  greatly 
  reduced 
  the 
  

   numbers 
  of 
  weevils 
  hibernating 
  in 
  infested 
  counties. 
  Though 
  this 
  

   season's 
  infestation 
  will 
  probably 
  be 
  lighter, 
  control 
  measures 
  should 
  

   not 
  be 
  omitted. 
  The 
  quarantine 
  line 
  for 
  Alabama 
  for 
  1913-14 
  is 
  shown 
  

   on 
  one 
  map, 
  a 
  20-mile 
  safety 
  zone 
  being 
  left 
  between 
  it 
  and 
  the 
  boll 
  

   weevil 
  line 
  for 
  1913 
  ; 
  the 
  other 
  map 
  shows 
  the 
  spread 
  of 
  the 
  weevil 
  

   from 
  1892-1913. 
  

  

  In 
  Bulletin 
  no. 
  71, 
  details 
  are 
  given 
  of 
  the 
  inauguration 
  in 
  Alabama 
  

   of 
  a 
  plan 
  for 
  County 
  Agricultural 
  Advisory 
  Committees, 
  composed 
  of 
  

   a 
  few 
  leading 
  men, 
  to 
  initiate 
  new 
  lines 
  of 
  effort 
  and 
  to 
  coordinate 
  all 
  

   forces 
  now 
  at 
  work 
  in 
  the 
  field. 
  It 
  is 
  hoped 
  that 
  such 
  a 
  group 
  of 
  men 
  

   will 
  be 
  able 
  to 
  organise 
  a 
  campaign 
  to 
  improve, 
  not 
  only 
  farming 
  

   methods, 
  but 
  the 
  social 
  welfare 
  of 
  the 
  farmers 
  in 
  a 
  wide 
  sense. 
  The 
  

   necessary 
  agricultural 
  and 
  economic 
  adjustments 
  will 
  be 
  made 
  

   gradually, 
  by 
  co-operative 
  action, 
  but 
  at 
  a 
  rate 
  that 
  will 
  offset 
  the 
  

   increasing 
  capacity 
  of 
  the 
  weevil 
  for 
  doing 
  harm 
  before 
  the 
  maximum 
  

   of 
  damage 
  usually 
  reached 
  in 
  the 
  3rd 
  or 
  4th 
  year 
  of 
  infestation. 
  It 
  

   is 
  hoped 
  that 
  these 
  committees 
  will 
  also 
  render 
  useful 
  service 
  among 
  

   the 
  dependant 
  illiterate 
  black 
  farmers 
  who 
  have 
  remained 
  uninfluenced 
  

   by 
  the 
  Farm 
  Demonstration 
  work 
  which 
  has 
  so 
  greatly 
  benefited 
  the 
  

   better 
  educated 
  farmers.
