  plots, 
  with 
  the 
  exception 
  of 
  Nos. 
  2, 
  5 
  

   and 
  6, 
  were

  on 
  10th 
  June 
  during 
  the 
  blossom- 
  

   ing 
  of 
  the 
  vines. 
  The 
  first 
  part 
  of 
  this 
  vineyard 
  was 
  not 
  treated 
  in 
  any 
  

   way 
  by 
  the 
  owner, 
  except 
  that 
  on 
  the 
  18th 
  July 
  it 
  was 
  again 
  sprayed 
  

   with 
  iron 
  sulphate 
  ; 
  Polychrosis 
  hotrana 
  was 
  found 
  there 
  in 
  greater 
  

   numbers 
  than 
  in 
  the 
  part 
  under 
  experimental 
  treatment, 
  but 
  the 
  

   vines 
  were 
  free 
  from 
  mildew, 
  which 
  is 
  attributed 
  to 
  the 
  effect 
  of 
  the 
  

   first 
  spraying 
  with 
  iron 
  sulphate 
  early 
  in 
  spring.

  The 
  following 
  is 
  a 
  simple 
  method 
  of 
  protecting 
  stored 
  beans 
  against 
  

   the 
  attacks 
  of 
  the 
  bean 
  Bruchus 
  : 
  — 
  Immediately 
  they 
  have 
  been 
  

   threshed 
  the 
  beans 
  are 
  put 
  into 
  cases 
  or 
  barrels. 
  For 
  every 
  hundred- 
  

   weight 
  of 
  beans 
  f 
  oz. 
  of 
  carbon 
  bisulphide 
  is 
  taken 
  and 
  placed 
  in 
  a 
  

   tumbler 
  covered 
  with 
  a 
  piece 
  of 
  cloth, 
  which 
  is 
  then 
  sunk 
  a 
  few 
  inches 
  

   into 
  the 
  mass 
  ot 
  beans 
  and 
  the 
  case 
  is 
  covered 
  with 
  a 
  blanket. 
  On 
  the 
  

   third 
  day 
  the 
  beans 
  are 
  taken 
  out 
  and 
  spread 
  about 
  in 
  order 
  to 
  free 
  

   them 
  from 
  the 
  smell 
  of 
  the 
  bisulphide.

  Four 
  species 
  of 
  " 
  white 
  grub 
  " 
  beetles 
  were 
  abundant 
  in 
  Minnesota 
  

   in 
  the 
  summer 
  of 
  1914. 
  Lachnosternafusca, 
  Frohl., 
  was 
  very 
  abundant 
  

   in 
  the 
  South 
  ; 
  Lachnosterna 
  rugosa, 
  extending 
  slightly 
  farther 
  north 
  

   to 
  Ottertail 
  ; 
  Lachnosterna 
  duika, 
  as 
  far 
  south 
  as 
  Brown 
  County 
  ; 
  

   Lachnosterna 
  grandis, 
  occurring 
  in 
  isolated 
  areas 
  from 
  Roseau 
  toWinona 
  

   Counties. 
  In 
  order 
  to 
  prevent 
  a 
  recurrence 
  of 
  this 
  pest 
  the 
  following 
  

   advice 
  is 
  given 
  : 
  Any 
  fields 
  which 
  have 
  been 
  in 
  sod 
  or 
  timothy 
  should 
  

   be 
  ploughed 
  early 
  and 
  pigs 
  let 
  into 
  the 
  fields 
  to 
  root 
  out 
  the 
  grubs 
  ; 
  

   they 
  should 
  not 
  be 
  planted 
  with 
  maize, 
  potatoes, 
  strawberries 
  or 
  other 
  

   plants 
  readily 
  attacked 
  by 
  Lachnosterna 
  grubs.
