  A

  one 
  from 
  Dr. 
  

   L. 
  R. 
  Jones 
  of 
  the 
  National 
  Research 
  Council, 
  to 
  the 
  effect 
  that 
  the 
  movement 
  

   fostered 
  by 
  the 
  Botanical 
  Society 
  to 
  secure 
  American 
  scientific 
  literature 
  for 
  

   Russian 
  scientists 
  had 
  met 
  with 
  success, 
  and 
  the 
  National 
  Research 
  Council 
  

   approved 
  this 
  project 
  and 
  had 
  appropriated 
  $1,000 
  to 
  carry 
  out 
  the 
  plan. 
  

   Mr. 
  Shapovalov's 
  efforts 
  as 
  a 
  committee 
  of 
  one 
  from 
  the 
  Botanical 
  Society 
  

   to 
  the 
  Washington 
  Academy 
  of 
  Sciences 
  to 
  consider 
  sending 
  literature 
  to 
  

   Russian 
  scientists 
  have 
  come 
  to 
  a 
  successful 
  end 
  and 
  he 
  desires 
  to 
  terminate 
  

   his 
  appointment. 
  

  

  Under 
  Brief 
  notes 
  and 
  reviews 
  of 
  literature 
  Dr. 
  Sh.\ntz 
  presented 
  the 
  second 
  

   volume 
  of 
  Burgerstein's 
  work 
  on 
  transpiration. 
  This 
  brings 
  the 
  review 
  of 
  

   literature 
  down 
  to 
  1920. 
  

  

  Mr. 
  M. 
  B. 
  Waite 
  told 
  of 
  seeing 
  specimens 
  of 
  Myrica 
  carolinensis 
  collected 
  

   near 
  Camp 
  Meade. 
  Dr. 
  Fairchild 
  stated 
  that 
  a 
  specimen 
  of 
  Myrica 
  rubra 
  

   from 
  China 
  collected 
  by 
  Mr. 
  Frank 
  Meyer 
  fruited 
  at 
  Chico, 
  California 
  and 
  at 
  

   Brooksville, 
  Florida. 
  This 
  species 
  represents 
  a 
  large 
  fruit 
  industry 
  in 
  China. 
  

  

  The 
  regular 
  program 
  was 
  as 
  follows: 
  

  

  F. 
  Wilson 
  Popenoe: 
  Hunting 
  new 
  plants 
  for 
  American 
  horticulture 
  in 
  

   the 
  highlands 
  of 
  Central 
  and 
  South 
  America 
  (illustrated). 
  

  

  For 
  some 
  years 
  the 
  Ofhce 
  of 
  Foreign 
  Seed 
  and 
  Plant 
  Introduction 
  of 
  the 
  

   Bureau 
  of 
  Plant 
  Industry 
  has 
  been 
  engaged 
  in 
  studying 
  the 
  wild 
  and 
  cultivated 
  

   avocados 
  of 
  tropical 
  America, 
  and 
  in 
  introducing 
  the 
  most 
  promising 
  ones 
  

   for 
  trial 
  in 
  California 
  and 
  Florida. 
  In 
  both 
  these 
  States 
  avocado 
  culture 
  

   is 
  now 
  established 
  on 
  a 
  commercial 
  basis, 
  and 
  the 
  demand 
  for 
  new 
  varieties 
  

   of 
  this 
  fruit, 
  to 
  fill 
  certain 
  needs 
  such 
  as 
  different 
  seasons 
  of 
  ripening, 
  is 
  keen. 
  

  

  The 
  two 
  years' 
  exploration 
  reviewed 
  in 
  this 
  talk 
  covered 
  the 
  most 
  impor 
  

   tant 
  avocado-growing 
  regions 
  between 
  Guatemala 
  and 
  Chile. 
  In 
  the 
  former 
  

   country, 
  where 
  16 
  months' 
  work 
  had 
  already 
  been 
  done 
  in 
  1916-1917, 
  a 
  large 
  

   quantity 
  of 
  avocado 
  seeds 
  of 
  known 
  parentage 
  was 
  obtained 
  for 
  use 
  in 
  pro- 
  

   ducing 
  stock-plants 
  on 
  which 
  to 
  graft 
  superior 
  varieties 
  of 
  this 
  fruit. 
  In 
  

   Costa 
  Rica 
  several 
  promising 
  kinds 
  were 
  obtained 
  and 
  sent 
  to 
  Washington, 
  

   also 
  seeds 
  of 
  the 
  aguacate 
  de 
  anis, 
  a 
  wild 
  avocado 
  of 
  considerable 
  interest. 
  

   In 
  Colombia 
  a 
  study 
  was 
  made 
  of 
  the 
  numerous 
  avocados 
  found 
  in 
  the 
  Santa 
  

   Marta 
  regions, 
  as 
  well 
  as 
  those 
  of 
  Cundinamarca 
  and 
  the 
  Cauca 
  Valley; 
  and 
  

   one 
  variety 
  was 
  sent 
  to 
  the 
  United 
  States 
  for 
  trial. 
  In 
  Ecuador 
  a 
  number 
  of 
  

   very 
  choice 
  forms 
  were 
  found 
  in 
  a 
  region 
  hitherto 
  unknown 
  as 
  a 
  producer 
  of 
  

   good 
  avocados. 
  A 
  brief 
  study 
  was 
  made 
  of 
  the 
  various 
  sorts 
  which 
  grow 
  in 
  

   Peru 
  and 
  Chile, 
  but 
  none 
  was 
  found 
  worthy 
  of 
  introduction 
  into 
  the 
  United 
  

   States.
