  It 
  is 
  interesting 
  to 
  know 
  that 
  the 
  Placentia 
  variety, 
  growing 
  

   within 
  a 
  stone's 
  throw 
  of 
  the 
  aforementioned 
  seedling 
  grove 
  and 
  

   under 
  identical 
  cultural 
  conditions, 
  was 
  blighted 
  to 
  the 
  extent 
  of 
  

   71.9 
  per 
  cent 
  on 
  the 
  same 
  date. 
  

  

  Observations 
  of 
  the 
  Prolific 
  (Ware's) 
  in 
  the 
  vicinity 
  of 
  the 
  above 
  

   mentioned 
  grove, 
  showed 
  less 
  than 
  1 
  per 
  cent 
  blighted 
  nuts 
  on 
  the 
  

   trees 
  and 
  practically 
  none 
  of 
  the 
  nuts 
  have 
  dropped 
  to 
  the 
  ground 
  

   at 
  the 
  present 
  time, 
  yet 
  in 
  the 
  past 
  this 
  variety 
  has 
  not 
  had 
  a 
  

   reputation 
  for 
  disease 
  immunity. 
  The 
  original 
  Chase 
  tree 
  was 
  

   observed 
  during 
  this 
  time 
  and 
  showed 
  a 
  percentage 
  of 
  37 
  per 
  cent 
  

   blighted 
  nuts. 
  These 
  examples 
  are 
  given 
  neither 
  in 
  support 
  of 
  

   any 
  particular 
  variety 
  nor 
  to 
  discredit 
  others, 
  but 
  are 
  noted 
  merely 
  

   to 
  call 
  attention 
  to 
  the 
  wide 
  variation, 
  and 
  this 
  variation 
  is 
  a 
  great 
  

   source 
  of 
  encouragement 
  in 
  our 
  endeavors 
  to 
  produce 
  a 
  disease 
  resist- 
  

   ant 
  variety. 
  

  

  Of 
  course 
  blight 
  immunity 
  is 
  not 
  the 
  only 
  factor 
  to 
  be 
  considered 
  

   in 
  selecting 
  a 
  variety 
  of 
  walnut. 
  A 
  profitable 
  yield 
  of 
  good 
  commer- 
  

   cial 
  nuts 
  is 
  the 
  real 
  test 
  of 
  the 
  superiority 
  of 
  any 
  variety. 
  A 
  very 
  

   heavy 
  yielding 
  tree 
  with 
  a 
  small 
  amount 
  of 
  blight 
  may 
  prove 
  more 
  

   profitable 
  than 
  a 
  light 
  yielding 
  variety 
  that 
  is 
  totally 
  immune 
  to 
  

   this 
  disease. 
  

  

  The 
  production 
  of 
  a 
  medium 
  grade 
  nut 
  which 
  would 
  grade 
  only 
  

   as 
  a 
  seedling 
  No 
  1, 
  might 
  prove 
  more 
  profitable 
  if 
  the 
  tree 
  is 
  at 
  

   least 
  partially 
  blight 
  immune 
  than 
  the 
  production 
  of 
  such 
  a 
  high 
  

   grade 
  nut 
  as 
  the 
  Placentia 
  with 
  its 
  susceptibility 
  to 
  blight. 
  These 
  

   things 
  must 
  be 
  considered 
  and 
  weighed 
  carefully 
  by 
  the 
  growers 
  who 
  

   are 
  planting 
  walnuts 
  in 
  the 
  blight 
  sections. 
  The 
  various 
  areas 
  

   where 
  wilnut 
  blight 
  is 
  not 
  a 
  factor 
  might 
  profitably 
  sacrifice 
  heavy 
  

   production 
  to 
  superior 
  quality. 
  

  

  From 
  our 
  present 
  knowledge 
  it 
  is 
  verj^ 
  apparent 
  that 
  the 
  disease 
  

   resistance 
  of 
  individual 
  trees 
  varies 
  considerably 
  from 
  year 
  to 
  year 
  

   and 
  under 
  different 
  soil 
  and 
  climatic 
  conditions. 
  The 
  thorough 
  

   testing 
  of 
  resistant 
  varieties 
  will 
  require 
  considerable 
  time. 
  

  

  Nut 
  Characteristics 
  

  

  The 
  character 
  of 
  the 
  nuts 
  is 
  as 
  variable 
  as 
  the 
  trees 
  themselves,, 
  

   not 
  only 
  in 
  the 
  exterior 
  appearance, 
  but 
  in 
  the 
  character 
  of 
  the 
  

   meats 
  as 
  well. 
  The 
  ideal 
  commercial 
  nut 
  should 
  be 
  of 
  medium 
  

   size, 
  about 
  one 
  and 
  one-eighth 
  to 
  one 
  and 
  one-half 
  inches 
  in 
  diameter, 
  

   of 
  regular 
  oval 
  form 
  somewhat 
  elongated, 
  with 
  smooth 
  surface, 
  and 
  

   light 
  brown 
  color, 
  and 
  uniform 
  for 
  these 
  characters. 
  The 
  cracking 
  

   quality 
  of 
  the 
  nuts 
  is 
  quite 
  as 
  important 
  as 
  their 
  exterior 
  appear-
