  ther 
  selection. 
  According 
  to 
  the 
  general 
  rule 
  

   of 
  pedigree-culture, 
  the 
  seeds 
  of 
  each 
  individual 
  

   plant 
  are 
  always 
  saved 
  and 
  sowed 
  separately. 
  

   This 
  is 
  done 
  even 
  with 
  such 
  species 
  as 
  the 
  

   clover, 
  which 
  are 
  infertile 
  when 
  self 
  -pollinated, 
  

   and 
  which 
  are 
  incapable 
  of 
  artificial 
  pollina- 
  

   tion 
  on 
  the 
  required 
  scale, 
  since 
  each 
  flower 
  pro- 
  

   duces 
  only 
  one 
  seed. 
  My 
  clover 
  was 
  always 
  

   left 
  free 
  to 
  be 
  pollinated 
  by 
  insects. 
  Obviously 
  

   this 
  must 
  have 
  led 
  to 
  a 
  diminution 
  of 
  the 
  differ- 
  

   entiating 
  characters 
  of 
  the 
  individual 
  plants. 
  

   But 
  this 
  does 
  not 
  go 
  far 
  enough 
  to 
  obliterate 
  

   the 
  differences, 
  and 
  the 
  selection 
  made 
  among 
  

   the 
  seedlings 
  will 
  always 
  throw 
  out 
  at 
  least 
  

   a 
  large 
  part 
  of 
  those 
  that 
  have 
  suffered 
  from 
  

   the 
  cross. 
  

  

  Leaving 
  this 
  discussion, 
  we 
  may 
  inquire 
  

   closer 
  into 
  the 
  nature 
  of 
  the 
  new 
  criterion 
  af- 
  

   forded 
  by 
  the 
  seedlings. 
  Two 
  methods 
  present 
  

   themselves. 
  First, 
  the 
  choice 
  of 
  the 
  best 
  seed- 
  

   lings. 
  In 
  the 
  second 
  place 
  it 
  becomes 
  possible 
  

   to 
  compare 
  the 
  parent-plants 
  by 
  counting 
  the 
  

   number 
  of 
  deviating 
  seedlings. 
  This 
  leads 
  to 
  

   the 
  establishment 
  of 
  a 
  percentage 
  for 
  every 
  

   single 
  parent, 
  and 
  gives 
  data 
  for 
  comparisons. 
  

   Two 
  or 
  three 
  hundreds 
  of 
  seeds 
  from 
  a 
  parent 
  

   may 
  easily 
  be 
  grown 
  in 
  one 
  pan, 
  and 
  in 
  this 
  

   way 
  a 
  sufficiently 
  high 
  degree 
  of 
  accuracy 
  

   may 
  be 
  reached. 
  Only 
  those 
  parents 
  that 
  give
