  as 
  the 
  best 
  variety 
  or 
  species. 
  Even 
  on 
  this 
  

   ground 
  it 
  must 
  be 
  considered 
  as 
  a 
  representa- 
  

   tive 
  of 
  a 
  separate 
  group 
  of 
  instances 
  of 
  the 
  uni- 
  

   versal 
  rule 
  of 
  systematic 
  reversions. 
  

  

  Of 
  late 
  the 
  same 
  mutation 
  has 
  occurred 
  in 
  the 
  

   garden 
  of 
  C. 
  A. 
  White 
  at 
  Washington. 
  The 
  

   parent 
  form 
  in 
  this 
  case 
  was 
  the 
  " 
  Acme," 
  of 
  

   the 
  ordinary 
  weak 
  and 
  spreading 
  habit 
  of 
  

   growth. 
  It 
  is 
  known 
  as 
  one 
  of 
  the 
  best 
  and 
  most 
  

   stable 
  of 
  the 
  varieties 
  and 
  was 
  grown 
  by 
  Mr. 
  

   White 
  for 
  many 
  years, 
  and 
  had 
  not 
  given 
  any 
  

   sign 
  of 
  a 
  tendency 
  towards 
  change. 
  Seeds 
  

   from 
  some 
  of 
  the 
  best 
  plants 
  in 
  1899 
  were 
  sown 
  

   the 
  following 
  spring, 
  and 
  the 
  young 
  seedlings 
  

   unexpectedly 
  exhibited 
  a 
  marked 
  difference 
  

   from 
  their 
  parents. 
  From 
  the 
  very 
  outset 
  they 
  

   were 
  more 
  strong 
  and 
  erect, 
  more 
  compact 
  and 
  

   of 
  a 
  darker 
  green 
  than 
  the 
  " 
  Acme." 
  When 
  

   they 
  reached 
  the 
  fruiting 
  stage 
  they 
  had 
  devel- 
  

   oped 
  into 
  typical 
  representatives 
  of 
  the 
  Lyco- 
  

   persicum 
  solanopsis 
  or 
  upright 
  division. 
  The 
  

   whole 
  lot 
  of 
  plants 
  comprised 
  only 
  some 
  30 
  

   specimens, 
  and 
  this 
  number, 
  of 
  course, 
  is 
  too 
  

   small 
  to 
  base 
  far-reaching 
  conclusions 
  upon. 
  

   But 
  all 
  of 
  the 
  lot 
  showed 
  this 
  type, 
  no 
  

   true 
  " 
  Acme 
  : 
  being 
  seen 
  among 
  them. 
  The 
  

   fruit 
  differed 
  in 
  flavor, 
  consistency 
  and 
  color 
  

   from 
  that 
  of 
  the 
  parent, 
  and 
  it 
  also 
  ripened 
  

   earlier 
  than 
  the 
  latter. 
  No 
  seed 
  was 
  saved 
  from
