  hybrids 
  between 
  the 
  chinquapin 
  and 
  the 
  American 
  chestnut. 
  One 
  

   of 
  these 
  trees 
  was 
  diseased, 
  the 
  other 
  had 
  no 
  disease 
  upon 
  it. 
  

  

  The 
  Japanese 
  chestnuts 
  have 
  been 
  known 
  for 
  a 
  long 
  time 
  to 
  be 
  

   highly 
  resistant 
  to 
  the 
  inroads 
  of 
  this 
  disease. 
  Some 
  may 
  be 
  im- 
  

   mune, 
  if 
  we 
  use 
  the 
  word 
  immune 
  in 
  a 
  very 
  loose 
  sense. 
  It 
  has 
  been 
  

   regarded 
  as 
  of 
  rather 
  coarse 
  quality 
  and 
  some 
  varieties 
  as 
  entirely 
  

   unfit 
  for 
  human 
  food. 
  This 
  is 
  true 
  of 
  many 
  of 
  the 
  Japanese 
  chest- 
  

   nuts, 
  but 
  I 
  have 
  recently 
  seen 
  some 
  which, 
  so 
  far 
  as 
  I 
  could 
  tell, 
  

   were 
  nearly 
  as 
  sweet 
  as 
  the 
  American 
  chestnut 
  and 
  Paragon 
  chest- 
  

   nut 
  which 
  I 
  tested 
  at 
  the 
  same 
  time 
  and 
  which 
  were 
  growing 
  side 
  

   by 
  side. 
  I 
  could 
  detect 
  very 
  little 
  difference 
  between 
  them. 
  The 
  

   Japanese 
  nuts 
  were 
  very 
  large, 
  considerably 
  larger 
  than 
  the 
  Para- 
  

   gon. 
  Whether 
  these 
  will 
  retain 
  their 
  sweetness 
  in 
  drying 
  I 
  cannot 
  

   say. 
  These 
  Japanese 
  chestnuts 
  are 
  seedlings, 
  and 
  are 
  known 
  as 
  the 
  

   Delaware, 
  the 
  Felton, 
  the 
  Kent 
  and 
  the 
  Henlopen. 
  Like 
  all 
  of 
  the 
  

   Japanese 
  chestnuts 
  they 
  are 
  highly 
  resistant 
  to 
  the 
  blight. 
  

  

  I 
  wish 
  to 
  call 
  your 
  attention 
  to 
  a 
  few 
  of 
  the 
  standard 
  Japanese 
  

   varieties 
  upon 
  which 
  I 
  have 
  made 
  observations. 
  These 
  were 
  all 
  

   grafted 
  trees, 
  that 
  is 
  the 
  Japanese 
  variety 
  was 
  grafted 
  on 
  Ameri- 
  

   can 
  stock. 
  The 
  McFarland 
  is 
  a 
  rather 
  well-known 
  variety. 
  Of 
  

   five 
  trees 
  which 
  I 
  have 
  had 
  under 
  observation, 
  all 
  of 
  them 
  became 
  

   diseased 
  below 
  the 
  graft 
  but 
  none 
  above 
  the 
  graft, 
  showing 
  the 
  

   resistance 
  of 
  the 
  Japanese 
  scion 
  on 
  American 
  stock. 
  I 
  think 
  this 
  

   is 
  given 
  out 
  as 
  a 
  Burbank 
  variety. 
  The 
  Hale 
  is 
  another 
  one 
  which 
  

   has 
  the 
  same 
  record 
  exactly. 
  On 
  the 
  Coe 
  I 
  have 
  seen 
  two 
  cases 
  of 
  

   the 
  disease 
  on 
  the 
  Japanese 
  part 
  and 
  several 
  cases 
  where 
  the 
  trees 
  

   are 
  diseased 
  below 
  the 
  graft. 
  The 
  Alpha, 
  one 
  of 
  the 
  Parry 
  varieties 
  

   holds 
  about 
  the 
  same 
  record 
  as 
  the 
  Coe 
  — 
  two 
  cases 
  of 
  disease 
  on 
  the 
  

   Japanese 
  part 
  and 
  several 
  below 
  the 
  graft. 
  The 
  Parry 
  Giant 
  has 
  

   been 
  considered 
  one 
  of 
  the 
  largest 
  nuts 
  ; 
  in 
  four 
  trees 
  observed 
  there 
  

   was 
  one 
  case 
  of 
  the 
  disease 
  on 
  the 
  Japanese 
  part 
  and 
  two 
  below 
  the 
  

   graft. 
  The 
  Superb 
  had 
  the 
  disease 
  below 
  the 
  graft 
  but 
  not 
  above 
  ; 
  

   the 
  Reliance 
  just 
  the 
  same 
  way. 
  Then 
  along 
  with 
  these 
  plots 
  were 
  

   one 
  variety 
  of 
  European, 
  the 
  Scott, 
  which 
  was 
  quite 
  as 
  susceptible 
  

   to 
  the 
  disease 
  as 
  any 
  other 
  European, 
  and 
  another 
  variety, 
  the 
  ori- 
  

   gin 
  of 
  which 
  I 
  do 
  not 
  know. 
  This 
  last 
  appears 
  to 
  be 
  something 
  of 
  a 
  

   hybrid 
  with 
  some 
  chinquapin 
  blood 
  in 
  it 
  — 
  whether 
  this 
  is 
  so 
  or 
  not 
  

   I 
  cannot 
  definitely 
  say 
  — 
  I 
  can 
  say 
  this, 
  however, 
  that 
  it 
  takes 
  the 
  

   disease 
  not 
  as 
  readily 
  as 
  the 
  European 
  but 
  raore 
  readily 
  than 
  the 
  

   Japanese. 
  

  

  Just 
  a 
  few 
  words 
  now 
  in 
  regard 
  to 
  the 
  present 
  distribution 
  of 
  the 
  

   chestnut 
  disease, 
  or 
  at 
  least 
  its 
  extended 
  distribution.
