  ing 
  hickories 
  with 
  walnuts, 
  and 
  crossing 
  hickories 
  with 
  each 
  other. 
  Five 
  

   hundred 
  years 
  from 
  now 
  we 
  shall 
  probably 
  find 
  extensive 
  orchards 
  of 
  

   such 
  hybrids 
  occupying 
  thousands 
  of 
  acres 
  of 
  land 
  which 
  is 
  now 
  practi- 
  

   cally 
  worthless. 
  The 
  hickories 
  are 
  to 
  furnish 
  a 
  substantial 
  part 
  of 
  the 
  

   food 
  supply 
  of 
  the 
  world 
  in 
  the 
  years 
  to 
  come. 
  At 
  the 
  present 
  time 
  

   wild 
  hickories 
  held 
  most 
  highly 
  in 
  esteem 
  are 
  : 
  H. 
  pecan, 
  H. 
  ovata, 
  H. 
  

   Carolinae-septentrionalis, 
  and 
  H. 
  laciniosa. 
  Several 
  other 
  kinds 
  have 
  

   edible 
  kernels, 
  sometimes 
  of 
  excellent 
  character, 
  but 
  not 
  readily 
  ob- 
  

   tained 
  except 
  by 
  boys 
  and 
  squirrels, 
  whose 
  time 
  is 
  not 
  valuable. 
  In 
  

   this 
  group 
  we 
  have 
  H. 
  alba, 
  H. 
  glabra, 
  H. 
  villosa, 
  H. 
  glabra 
  pallida, 
  H. 
  

   glabra 
  odorata, 
  H. 
  glabra 
  mici'ocarpa, 
  H. 
  Mexicana, 
  H. 
  Buckleyi, 
  and 
  

   H. 
  myristicaeformis. 
  In 
  another 
  group 
  of 
  hickories 
  with 
  temptingly 
  

   thin 
  shells 
  and 
  plump 
  kernels, 
  we 
  have 
  a 
  bitter 
  or 
  astringent 
  pellicle 
  

   of 
  the 
  kernel. 
  This 
  group 
  contains 
  H. 
  Texana, 
  H. 
  minima, 
  and 
  H. 
  

   aquatica. 
  Sometimes 
  in 
  the 
  bitter 
  group 
  we 
  find 
  individual 
  trees 
  with 
  

   edible 
  nuts, 
  and 
  it 
  is 
  not 
  unlikely 
  that 
  some 
  of 
  them 
  represent 
  hybrids 
  

   in 
  which 
  the 
  bitter 
  and 
  astringent 
  qualities 
  have 
  been 
  recessive. 
  

  

  Among 
  the 
  desirable 
  species 
  of 
  wild 
  hickories 
  there 
  is 
  much 
  varia- 
  

   tion 
  in 
  character, 
  and 
  selection 
  of 
  trees 
  for 
  propagation 
  is 
  in 
  its 
  infancy. 
  

   One 
  reason 
  for 
  this 
  has 
  been 
  the 
  difficulty 
  of 
  transplanting 
  hickories. 
  

   Another 
  reason 
  is 
  the 
  fact 
  that 
  hickories 
  do 
  not 
  come 
  true 
  to 
  parent 
  

   type 
  from 
  seed. 
  A 
  third 
  reason 
  is 
  the 
  length 
  of 
  time 
  required 
  for 
  seed- 
  

   ling 
  hickories 
  to 
  come 
  into 
  bearing. 
  

  

  Concerning 
  the 
  first 
  reason, 
  the 
  enormous 
  taproot 
  of 
  young 
  hick- 
  

   ories 
  requires 
  so 
  much 
  pabulum 
  for 
  maintenance 
  that 
  when 
  the 
  trees 
  

   are 
  transplanted, 
  with 
  destruction 
  of 
  root-hairs 
  along 
  with 
  the 
  feeding 
  

   roots, 
  transplanted 
  stocks 
  nmy 
  remain 
  a 
  year 
  or 
  two 
  years 
  in 
  the 
  

   ground 
  before 
  they 
  are 
  ready 
  to 
  send 
  out 
  buds 
  from 
  the 
  top. 
  On 
  this 
  

   account, 
  the 
  Stringfellow 
  method 
  has 
  in 
  my 
  locality 
  proven 
  of 
  value. 
  

   This 
  consists 
  in 
  extreme 
  cutting 
  back 
  of 
  root 
  and 
  top, 
  leaving 
  little 
  

   more 
  than 
  a 
  short 
  club 
  for 
  transplantation. 
  The 
  short 
  club 
  does 
  not 
  

   reduirr 
  much 
  pabulum 
  for 
  maintenance, 
  and 
  new 
  feeding 
  roots 
  with 
  

   their 
  root-haii-s 
  get 
  the 
  club 
  under 
  way 
  quickly, 
  because 
  there 
  is 
  little 
  

   useless 
  load 
  for 
  them 
  to 
  carry. 
  The 
  Stringfellow 
  method 
  further 
  in- 
  

   ohules 
  the 
  idea 
  that 
  stock 
  should 
  be 
  planted 
  in 
  very 
  hard 
  ground, 
  and 
  

   seems 
  to 
  be 
  practicable 
  with 
  the 
  hickories. 
  The 
  root-hairs 
  which 
  take 
  up 
  

   nourishment 
  from 
  the 
  soil 
  find 
  it 
  difficult 
  to 
  carry 
  on 
  osmosis 
  in 
  loose 
  

   soil. 
  The 
  close 
  contact 
  obtained 
  by 
  forcing 
  a 
  way 
  through 
  compact 
  soil 
  

   facilitates 
  feeding. 
  On 
  this 
  account, 
  autumn 
  is 
  perhaps 
  a 
  better 
  time 
  

   for 
  transplantation 
  of 
  hickories, 
  in 
  the 
  northern 
  latitudes, 
  at 
  least. 
  

   Callus 
  forms 
  over 
  the 
  ends 
  of 
  cut 
  roots 
  at 
  all 
  times 
  when 
  the 
  ground 
  is 
  

   not 
  frozen, 
  and 
  the 
  more 
  complete 
  the 
  callus 
  formation 
  the 
  more 
  readily 
  

   are 
  feeding 
  roots 
  sent 
  out.
