  Six 
  sugar 
  corns: 
  Crosby's 
  Early, 
  Country 
  Gentleman, 
  Ruby 
  

   Sweet, 
  Golden 
  Bantam 
  Sweet, 
  Golden 
  Cream 
  Sweet, 
  and 
  

   Stoweirs 
  Evergreen. 
  

  

  

  

  Five 
  flour 
  corns: 
  Red 
  Squaw, 
  Blue 
  Flour 
  (Pink 
  Flour, 
  Yellow 
  

  

  Flour, 
  and 
  White 
  Flour 
  from 
  Ankara 
  Indians). 
  

   Six 
  pop 
  corns: 
  Eight 
  Rowed 
  Pop, 
  White 
  Rice, 
  Black 
  Beauty 
  Pop, 
  

  

  Snowflake, 
  Golden 
  Tom 
  Thumb, 
  and 
  California 
  Golden. 
  

  

  With 
  the 
  exception 
  of 
  the 
  corns 
  from 
  the 
  Arikara 
  Indians, 
  

   these 
  are 
  all 
  fairly 
  common 
  and 
  well 
  marked 
  races 
  which 
  I 
  have 
  

   grown 
  in 
  selfed 
  or 
  inbred 
  cultures 
  parallel 
  to 
  my 
  experiments 
  with 
  

   crossing 
  and 
  have 
  found 
  to 
  come 
  true 
  to 
  type 
  except 
  for 
  such 
  

   fluctuating 
  variations 
  as 
  I 
  am 
  noting 
  in 
  connection 
  with 
  the 
  expe- 
  

   riments. 
  That 
  such 
  fluctuating 
  variations 
  occur 
  in 
  both 
  sexually 
  

   and 
  asexually 
  reproduced 
  series, 
  is 
  well 
  established 
  as 
  noted, 
  but 
  

   that 
  sexual 
  reproduction 
  favors 
  their 
  occurrence 
  is, 
  it 
  seems 
  to 
  me, 
  

   shown 
  especially 
  well 
  by 
  the 
  results 
  obtained 
  in 
  breeding 
  corn. 
  

  

  My 
  results 
  can 
  best 
  be 
  presented 
  perhaps 
  by 
  reproducing 
  

   life-size 
  photographs 
  of 
  a 
  series 
  of 
  ears 
  (Plates 
  1-3) 
  illustrating 
  

   the 
  actual 
  number, 
  distribution, 
  appearance, 
  etc., 
  of 
  these 
  inter- 
  

   mediates 
  from 
  a 
  characteristic 
  generation 
  in 
  a 
  series 
  of 
  experiments 
  

   which 
  I 
  have 
  carried 
  on 
  now 
  for 
  some 
  six 
  years. 
  These 
  figures 
  can 
  

   be 
  regarded 
  as 
  typical 
  of 
  the 
  fuller 
  series 
  reported 
  statisrically 
  in 
  the 
  

   tables, 
  which 
  show 
  the 
  proportions 
  of 
  the 
  various 
  classes 
  of 
  kernels 
  

   in 
  the 
  successive 
  generations. 
  They 
  represent 
  a 
  stage 
  in 
  which 
  the 
  

   injurious 
  efl^ects 
  of 
  selfing 
  are 
  not 
  yet 
  seriously 
  manifest. 
  They 
  

   are 
  also 
  illustrative 
  of 
  my 
  results 
  in 
  all 
  the 
  sweet 
  with 
  flint 
  or 
  

   dent 
  combinations 
  noted 
  below, 
  with 
  many 
  of 
  which 
  I 
  have 
  worked 
  

   for 
  some 
  six 
  or 
  seven 
  years. 
  I 
  am 
  reporting 
  also 
  on 
  sweet 
  with 
  pop 
  

   corn 
  crosses 
  and 
  some 
  further 
  special 
  cases 
  in 
  another 
  paper.

  Thorburn

  the

  Black 
  Mexican 
  sweet 
  corn,

   obtained 
  from 
  Thorburn. 
  I 
  am 
  not 
  reproducing 
  figures 
  of 
  these 
  

   two 
  parent 
  races 
  since 
  the 
  types 
  are 
  well 
  known 
  and,

  both 
  

   ears 
  are 
  undersized

  tip,
