  In 
  taking 
  up 
  the 
  question 
  of 
  nut 
  diseases 
  it 
  is 
  liardly 
  proper^ 
  

   perhaps, 
  to 
  take 
  too 
  narrow 
  a 
  view 
  of 
  it 
  and 
  I 
  will, 
  therefore, 
  mention 
  

   some 
  of 
  the 
  other 
  work 
  being 
  done 
  here 
  in 
  "Washington 
  that 
  is 
  of 
  

   interest 
  to 
  the 
  Northern 
  Nut 
  Growers 
  Association. 
  

  

  You 
  all 
  know 
  of 
  the 
  pomological 
  work 
  being 
  done 
  on 
  nuts, 
  and 
  I 
  

   hardly 
  need 
  mention 
  the 
  work 
  now 
  being 
  carried 
  on 
  by 
  Mr. 
  C. 
  A. 
  

   Reed, 
  a 
  member 
  of 
  this 
  association. 
  It 
  might 
  be 
  well 
  to 
  remind 
  you 
  

   that 
  the 
  work 
  was 
  started 
  by 
  Mr. 
  Van 
  Deman 
  some 
  twenty-five 
  years 
  

   ago, 
  and 
  continued 
  by 
  Mr. 
  Corsa, 
  and 
  a 
  report 
  was 
  issued 
  some 
  

   fifteen 
  years 
  ago. 
  It 
  was 
  taken 
  up 
  later 
  by 
  Mr. 
  William 
  A. 
  Taylor. 
  

  

  The 
  plant 
  introduction 
  work 
  of 
  Mr. 
  D. 
  Q. 
  Fairchild 
  should 
  be 
  

   mentioned. 
  He 
  is 
  scouring 
  the 
  world 
  for 
  new 
  nuts 
  of 
  all 
  kinds 
  for 
  

   the 
  northern 
  and 
  southern, 
  eastern 
  and 
  western 
  United 
  States, 
  and 
  

   introducing 
  them 
  into 
  this 
  country. 
  The 
  diseases 
  of 
  those 
  nuts 
  are 
  

   studied 
  by 
  Mr. 
  Orton 
  in 
  the 
  Cotton 
  Truck 
  Division 
  of 
  our 
  depart- 
  

   ment. 
  

  

  Outside 
  of 
  the 
  Bureau 
  of 
  Plant 
  Industry 
  also 
  there 
  is 
  some 
  work 
  

   being 
  done 
  on 
  nut 
  trees. 
  The 
  insects 
  attacking 
  cultivated 
  nuts 
  are 
  

   studied 
  by 
  Professor 
  A. 
  L. 
  Quaintance, 
  of 
  the 
  Bureau 
  of 
  Ento- 
  

   mology; 
  along 
  with 
  the 
  deciduous 
  fruit 
  insects. 
  The 
  insects 
  attack- 
  

   ing 
  forest 
  nut 
  trees 
  are 
  studied 
  by 
  Dr. 
  Hopkins 
  of 
  the 
  same 
  Bureau 
  

   in 
  the 
  laboratory 
  that 
  studies 
  the 
  forest 
  insects. 
  Of 
  course 
  the 
  nut 
  

   trees, 
  as 
  forest 
  trees, 
  are 
  studied 
  in 
  the 
  Forest 
  Service 
  about 
  which 
  

   you 
  all 
  know. 
  

  

  One 
  thing 
  more 
  that 
  I 
  would 
  like 
  to 
  say, 
  in 
  way 
  of 
  explanation 
  or 
  

   apology, 
  is 
  in 
  regard 
  to 
  criticism 
  of 
  the 
  Department 
  for 
  not 
  more 
  

   thoroughly 
  attacking 
  the 
  filbert 
  blight. 
  Only 
  forty-five 
  thousand 
  

   dollars 
  are 
  appropriated 
  by 
  Congress 
  for 
  the 
  investigation 
  of 
  the 
  

   entire 
  fruit 
  disease 
  problem 
  of 
  the 
  United 
  States. 
  That 
  includes 
  

   the 
  great 
  citrus 
  industry; 
  everything, 
  in 
  fact, 
  from 
  cranberries 
  on 
  

   Cape 
  Cod 
  and 
  the 
  mouth 
  of 
  the 
  Columbia 
  River 
  to 
  grape 
  fruit 
  in 
  

   Florida 
  or 
  apples 
  in 
  New 
  York. 
  It 
  includes 
  the 
  subject 
  of 
  all 
  the 
  

   nut 
  diseases, 
  and 
  that 
  means 
  the 
  problem 
  of 
  the 
  diseases 
  of 
  the 
  

   pecan, 
  of 
  walnut 
  bacteriosis 
  — 
  that 
  is 
  a 
  big 
  problem 
  — 
  in 
  southern 
  

   California, 
  and 
  more 
  or 
  less 
  in 
  other 
  parts 
  of 
  California, 
  our 
  great 
  

   apple 
  industry, 
  the 
  peach 
  yellows, 
  the 
  pear 
  blight, 
  etc. 
  When 
  it 
  

   comes 
  to 
  parceling 
  that 
  out 
  it 
  only 
  leaves 
  about 
  three 
  thousand 
  

   dollars 
  for 
  nut 
  diseases, 
  and 
  thirty-five 
  hundred 
  dollars 
  for 
  studying
