  being 
  more 
  largely 
  cultivated 
  in 
  some 
  countries. 
  

   It 
  has 
  one 
  great 
  drawback: 
  it 
  never 
  comes 
  

   wholly 
  true 
  from 
  seed. 
  It 
  may 
  be 
  grown 
  in 
  

   full 
  isolation, 
  and 
  carefully 
  selected, 
  all 
  red 
  or 
  

   nearly 
  monochromatic 
  samples 
  being 
  rooted 
  out 
  

   long 
  before 
  blooming, 
  but 
  nevertheless 
  the 
  seed 
  

   will 
  always 
  produce 
  some 
  red 
  roots. 
  The 
  most 
  

   careful 
  selection, 
  pursued 
  through 
  a 
  number 
  

   of 
  years, 
  has 
  not 
  been 
  sufficient 
  to 
  get 
  rid 
  of 
  

   this 
  regular 
  occurrence 
  of 
  reversionary 
  individ- 
  

   uals. 
  Seed-growers 
  receive 
  many 
  complaints 
  

   from 
  their 
  clients 
  on 
  this 
  account, 
  but 
  they 
  are 
  

   not 
  able 
  to 
  remove 
  the 
  difficulty. 
  This 
  experi- 
  

   ence 
  is 
  in 
  full 
  agreement 
  with 
  the 
  experimental 
  

   evidence 
  given 
  by 
  the 
  snapdragon, 
  and 
  it 
  would 
  

   certainly 
  be 
  very 
  interesting 
  to 
  make 
  a 
  complete 
  

   pedigree-culture 
  with 
  the 
  radishes 
  to 
  test 
  

   definitely 
  their 
  compliance 
  with 
  the 
  rules 
  ob- 
  

   served 
  for 
  striped 
  flowers. 
  

  

  Horticulturists 
  in 
  such 
  cases 
  are 
  in 
  the 
  habit 
  

   of 
  limiting 
  themselves 
  to 
  the 
  sale 
  of 
  so-called 
  

   mixed 
  seeds. 
  From 
  these 
  no 
  client 
  expects 
  pu- 
  

   rity, 
  and 
  the 
  normal 
  and 
  hereditary 
  diversity 
  

   of 
  types 
  is 
  here 
  in 
  some 
  sense 
  concealed 
  under 
  

   the 
  impurities 
  included 
  in 
  the 
  mixture 
  from 
  

   lack 
  of 
  selection. 
  Such 
  cases 
  invite 
  scrutiny, 
  

   and 
  would, 
  no 
  doubt, 
  with 
  the 
  methods 
  of 
  isola- 
  

   tion, 
  artificial 
  pollination, 
  and 
  the 
  sowing 
  of 
  

   the 
  seeds 
  separately 
  from 
  each 
  parent, 
  yield
