  J- 
  -B^^ss 
  objects 
  to 
  the 
  usually 
  accepted 
  notion 
  that 
  the 
  sieve 
  portion 
  of 
  

   the 
  fibro 
  vascular 
  bundle 
  has 
  for 
  its 
  special 
  function 
  the 
  conduction 
  of 
  

   the 
  nitrogenous 
  materials, 
  on 
  the 
  grounds 
  that 
  the 
  sieve 
  tubes 
  are 
  

   wanting 
  at 
  the 
  place 
  where 
  there 
  is 
  the 
  most 
  need 
  of 
  nitrogenous 
  mater- 
  

   ials, 
  viz^, 
  the 
  growing 
  points; 
  and 
  that 
  the 
  conductivity 
  of 
  the 
  tubes 
  is 
  

   not 
  sufficient 
  on 
  account 
  of 
  the 
  small 
  size 
  of 
  the 
  pores, 
  the 
  autumnal 
  

   closing 
  with 
  callus, 
  and 
  the 
  comparatively 
  small 
  number 
  of 
  the 
  tubes, 
  

   from 
  his 
  researches 
  he 
  comes 
  to 
  the 
  conclusion 
  that 
  no 
  distributive 
  con- 
  

   auction 
  of 
  nitrogenous 
  materials 
  takes 
  place 
  through 
  the 
  sieve 
  tubes.but 
  

   ttiat 
  their 
  function 
  is 
  to 
  temporarily 
  store 
  nourishment 
  for 
  the 
  cambium 
  

   and 
  tiie 
  production 
  of 
  wood, 
  just 
  as 
  the 
  starch 
  sheath 
  does 
  for 
  the 
  bast.
