  This 
  Tiiothod 
  served 
  a 
  purpose 
  in 
  advancing 
  onr 
  knowledge 
  of 
  

   the 
  subject, 
  bnt 
  not 
  enough 
  grafts 
  caught 
  to 
  encourage 
  me 
  greatly. 
  

   Following 
  out 
  the 
  same 
  line 
  of 
  tli 
  ought, 
  I 
  began 
  this 
  year 
  by 
  making 
  

   union 
  between 
  stock 
  and 
  scion 
  according 
  to 
  inarch 
  principles. 
  The 
  

   scion 
  instead 
  of 
  remaining 
  attached 
  to 
  its 
  parent 
  plant, 
  according 
  

   to 
  former 
  inarching 
  method, 
  had 
  been 
  transferred 
  to 
  the 
  stock, 
  

   leaving 
  two 
  or 
  three 
  inches 
  of 
  scion 
  free 
  below 
  the 
  point 
  of 
  grafting, 
  

   as 
  illustrated 
  in 
  the 
  drawing. 
  The 
  proximal 
  part 
  of 
  the 
  scion 
  was 
  

   then 
  inserted 
  into 
  a 
  test 
  tube 
  containing 
  water. 
  In 
  this 
  case, 
  as 
  

   with 
  placing 
  tlu' 
  test 
  tube 
  at 
  the 
  top 
  of 
  the 
  scion, 
  difficulty 
  was 
  

   fountl 
  in 
  prexenting 
  the 
  growth 
  of 
  microorganisms 
  in 
  the 
  water. 
  

   The 
  addition 
  of 
  benzoate 
  of 
  soda, 
  borax, 
  boracic 
  acid, 
  and 
  sulphate 
  

   of 
  eopj)er, 
  while 
  preventing 
  the 
  development 
  of 
  microorganisms, 
  

   seemed 
  also 
  to 
  be 
  objectionable 
  to 
  the 
  physiologic 
  processes 
  of 
  the 
  

   plant. 
  It 
  occurred 
  to 
  me 
  that 
  the 
  principle 
  of 
  the 
  balanced 
  aqua- 
  

   rium 
  might 
  be 
  applied, 
  and 
  acting 
  upon 
  this 
  idea 
  specimens 
  of 
  a 
  

   pond 
  weed 
  (TTtricularia) 
  were 
  introduced 
  into 
  the 
  test 
  tubes. 
  This 
  

   seemed 
  to 
  settle 
  the 
  water 
  question 
  completely, 
  but 
  it 
  was 
  well 
  along 
  

   in 
  the 
  summer 
  before 
  I 
  made 
  grafts 
  and 
  applied 
  this 
  principle. 
  

   From 
  one 
  to 
  four 
  leaves, 
  or 
  parts 
  of 
  leaves, 
  were 
  left 
  upon 
  grafts 
  

   wliieli 
  were 
  applied 
  to 
  stocks 
  according 
  to 
  this 
  new 
  inarching 
  

   method. 
  All 
  of 
  these 
  leaves 
  remained 
  green 
  until 
  autumn, 
  and 
  fell 
  

   with 
  other 
  autumn 
  leaves 
  of 
  the 
  stock. 
  Two 
  specimens 
  which 
  I 
  have 
  

   cut 
  away 
  for 
  examination 
  seemed 
  to 
  show 
  a 
  very 
  good 
  union 
  between 
  

   stock 
  and 
  scion. 
  

  

  I 
  am 
  presenting 
  a 
  description 
  of 
  the 
  new 
  inarching 
  method 
  

   promptly, 
  before 
  obtaining 
  more 
  extensive 
  statistics, 
  in 
  order 
  that 
  

   members 
  of 
  this 
  society 
  may 
  apply 
  it 
  experimentally 
  next 
  spring. 
  

   Should 
  it 
  succeed 
  according 
  to 
  present 
  promise, 
  it 
  will 
  allow 
  nurs- 
  

   erymen 
  at 
  least 
  two 
  months 
  of 
  grafting 
  season, 
  and 
  they 
  will 
  not 
  

   have 
  to 
  rush 
  their 
  work. 
  In 
  addition 
  it 
  will 
  perhaps 
  open 
  up 
  a 
  

   method 
  of 
  grafting 
  which 
  may 
  be 
  employed 
  freely 
  with 
  nut 
  trees 
  

   in 
  tlu^ 
  northern 
  states. 
  

  

  Another 
  unusual 
  method 
  for 
  propagating 
  nut 
  trees 
  consists 
  in 
  

   facilitating 
  the 
  development 
  of 
  adventitious 
  buds 
  from 
  the 
  roots 
  of 
  

   some 
  particularly 
  desirable 
  tree. 
  I 
  do 
  not 
  know 
  at 
  the 
  present 
  time 
  

   how 
  many 
  species 
  of 
  nut 
  trees 
  will 
  develop 
  adventitious 
  root 
  buds, 
  

   as 
  my 
  experiments 
  liave 
  been 
  confined 
  to 
  roots 
  of 
  the 
  shagbark 
  

   liickory, 
  beech, 
  and 
  hazel. 
  Segments 
  of 
  roots 
  of 
  these 
  three 
  species 
  

   when 
  placed 
  in 
  sand, 
  allowing 
  an 
  inch 
  or 
  so 
  to 
  protrude, 
  will 
  de- 
  

   velop 
  adventitious 
  buds 
  if 
  they 
  are 
  kept 
  warm 
  and 
  moist. 
  Various 
  

   lengtlis 
  of 
  root 
  segments 
  have 
  been 
  employed, 
  ranging 
  from 
  two
