  been 
  treated

  Hopkins

  of 
  the 
  Bureau 
  of 
  

   Entomology. 
  

  

  Attention 
  should 
  be 
  called 
  to 
  an 
  insect 
  rather 
  recently 
  introduced 
  

   into 
  the 
  New 
  England 
  States, 
  which 
  will 
  probably 
  attack 
  nut 
  crops, 
  

   namely, 
  the 
  so-called 
  leopard 
  moth, 
  already 
  indicated 
  in 
  the 
  list 
  of 
  

   titles 
  on 
  nut 
  insects. 
  This 
  pest 
  will 
  prove 
  a 
  difficult 
  one 
  to 
  control, 
  

   as 
  it 
  infests 
  the 
  trunk 
  and 
  larger 
  limbs. 
  

  

  The 
  whole 
  question 
  of 
  the 
  control 
  of 
  nut 
  insects 
  is 
  complicated 
  

   by 
  the 
  often 
  enormous 
  size 
  of 
  the 
  trees, 
  so 
  that 
  operations, 
  effective 
  

   in 
  the 
  control 
  of 
  insects, 
  say 
  affecting 
  the 
  apple, 
  are 
  not 
  entirely 
  

   practical. 
  It 
  is 
  a 
  point 
  to 
  be 
  determined 
  whether 
  it 
  will 
  be 
  profit- 
  

   able 
  to 
  spray 
  large 
  nut 
  trees, 
  such 
  as 
  the 
  pecan. 
  In 
  some 
  instances 
  

   we 
  believe 
  that 
  it 
  will 
  be, 
  and 
  the 
  Bureau 
  of 
  Entomology 
  now 
  has 
  

   in 
  Florida 
  one 
  of 
  the 
  large 
  power 
  spraying 
  outfits, 
  formerly 
  in 
  use 
  

   in 
  the 
  gipsy 
  moth 
  spraying, 
  to 
  determine 
  the 
  cost 
  and 
  benefits 
  of 
  

   such 
  work. 
  

  

  In 
  concluding 
  these 
  brief 
  remarks 
  I 
  wish 
  again 
  to 
  reiterate 
  my 
  

   pleasure 
  in 
  having 
  the 
  opportunity 
  of 
  appearing 
  before 
  you, 
  and 
  

   to 
  assure 
  you 
  of 
  the 
  interest 
  of 
  the 
  Department 
  in 
  the 
  insect 
  prob- 
  

   lems 
  confronting 
  nut 
  growers. 
  Nut 
  culture 
  is 
  bound 
  to 
  increase 
  

   enormously 
  and 
  insect 
  injuries 
  will 
  probably 
  correspondingly 
  in- 
  

   crease. 
  I 
  believe, 
  however, 
  that 
  these 
  injuries 
  will 
  be 
  found 
  con- 
  

   trollable, 
  as 
  has 
  been 
  determined 
  to 
  be 
  true 
  in 
  the 
  case 
  of 
  practically 
  

   all 
  important 
  native 
  or 
  introduced 
  crops. 
  

  

  The 
  Chairman: 
  We 
  are 
  glad 
  that 
  Professor 
  Quaintance 
  has 
  

   told 
  us 
  about 
  the 
  different 
  bulletins. 
  The 
  secretary 
  will 
  have 
  a 
  list 
  

   of 
  these. 
  I 
  am 
  now 
  going 
  to 
  call 
  for 
  Mr. 
  Rhodes, 
  who 
  is 
  an 
  expert 
  

   propagator 
  of 
  Persian 
  walnuts, 
  and 
  he 
  is 
  going 
  to 
  give 
  a 
  demon- 
  

   stration 
  on 
  methods 
  of 
  propagating 
  the 
  walnut. 
  

  

  Mr. 
  Rhodes 
  : 
  I 
  am 
  employed 
  over 
  at 
  Arlington 
  and 
  I 
  have 
  been 
  

   helping 
  Professor 
  Lake 
  in 
  his 
  work 
  there 
  at 
  the 
  farm. 
  Last 
  year 
  

   about 
  the 
  15th 
  of 
  July 
  we 
  put 
  in 
  about 
  seventy-five 
  grafts 
  using 
  the 
  

   cleft 
  graft, 
  and 
  the 
  side 
  graft, 
  and 
  at 
  the 
  same 
  time 
  we 
  put 
  in 
  some 
  

   chip 
  buds. 
  Professor 
  Lake 
  has 
  a 
  little 
  instrument 
  which 
  is 
  known 
  

   as 
  a 
  chip 
  budder. 
  We 
  used 
  an 
  ordinary 
  bandage, 
  such 
  as 
  surgeons 
  

   have, 
  which 
  we 
  dipped 
  in 
  a 
  mixture 
  of 
  about 
  two 
  parts 
  wax, 
  one 
  

   part 
  tallow 
  and 
  one 
  part 
  rosin. 
  We 
  put 
  the 
  bandage 
  in 
  when 
  the 
  

   solution 
  was 
  at 
  a 
  boil 
  — 
  that 
  made 
  it 
  sticky 
  enough 
  to 
  hold 
  to 
  the 
  

   bud, 
  and 
  then 
  we 
  cut 
  a 
  hole 
  large 
  enough 
  for 
  the 
  bud 
  to 
  come 
  out. 
  

   We 
  found 
  budding 
  at 
  that 
  season, 
  in 
  August, 
  more 
  successful 
  than 
  

   grafting. 
  The 
  stocks 
  were 
  about 
  two 
  inches 
  in 
  diameter 
  ; 
  we 
  put 
  in 
  

   grafts 
  anywhere 
  from 
  two 
  to 
  tliree 
  feet 
  above 
  the 
  ground, 
  sometimes
