  thought 
  can 
  contribute 
  to 
  the 
  production 
  of 
  better 
  persimmons, 
  and 
  

   this 
  inventory 
  contains 
  species 
  from 
  Mauritius, 
  Bengal, 
  the 
  Caucasus, 
  

   and 
  Mexico. 
  

  

  The 
  total 
  number 
  of 
  introductions 
  listed, 
  844, 
  is 
  an 
  average 
  of 
  over 
  

   280 
  a 
  month, 
  or 
  10 
  introductions 
  each 
  official 
  day, 
  which 
  is 
  more 
  than 
  

   16 
  per 
  cent 
  above 
  the 
  average 
  for 
  any 
  previous 
  period, 
  notwithstand- 
  

   ing 
  the 
  fact 
  that 
  only 
  one 
  explorer 
  has 
  been 
  in 
  the 
  field 
  during 
  this 
  

   time. 
  This 
  may 
  be 
  taken 
  as 
  an 
  indication 
  of 
  the 
  increase 
  in 
  requests 
  

   from 
  experimenters 
  for 
  new 
  material 
  and 
  in 
  foreign 
  correspondence 
  

   which 
  leads 
  to 
  the 
  discovery 
  of 
  valuable 
  foreign 
  plants 
  not 
  heretofore 
  

   introduced. 
  

  

  Special 
  attention 
  is 
  called 
  to 
  the 
  increasing 
  quantity 
  of 
  technical 
  

   botanical 
  matter 
  included, 
  particularly 
  the 
  geographic 
  distribution 
  

   of 
  the 
  rarer 
  species. 
  For 
  this, 
  as 
  well 
  as 
  for 
  the 
  determination 
  of 
  the 
  

   species, 
  Mr. 
  H. 
  C. 
  Skeels, 
  working 
  under 
  the 
  supervision 
  of 
  Mr. 
  

   Frederick 
  V. 
  Coville, 
  of 
  the 
  Office 
  of 
  Taxonomic 
  and 
  Range

   gations, 
  is 
  responsible. 
  Miss 
  Mary 
  A. 
  Austin, 
  as 
  heretofore, 
  has 
  had 
  

   charge 
  of 
  the 
  preparation 
  of 
  the 
  inventory.
