  Trees 
  84 
  and 
  85 
  are 
  blossoming 
  pretty 
  fully 
  and 
  the 
  leaves 
  

   have 
  started 
  well. 
  The 
  leaves 
  are 
  nearly 
  unfolded 
  on 
  tree 
  106 
  and 
  there 
  

   appear 
  to 
  be 
  few 
  blossoms. 
  The 
  leaves 
  are 
  just 
  starting 
  on 
  tree 
  115.

  The 
  abundant 
  blossoms 
  are 
  out 
  on 
  tree 
  84, 
  and 
  they 
  have 
  

   started 
  well 
  on 
  tree 
  85. 
  The 
  rather 
  abundant 
  foHage 
  is 
  pretty 
  well 
  

   developed 
  on 
  tree 
  106 
  and 
  the 
  blossoms 
  are 
  somewhat 
  abundant. 
  The 
  

   rather 
  scattering 
  leaves 
  on 
  tree 
  115 
  are 
  pretty 
  well 
  out. 
  This 
  last 
  tree 
  

   was 
  rather 
  badly 
  infested 
  at 
  the 
  beginning 
  of 
  the 
  experiment.
