  In 
  addition 
  to 
  avocados, 
  numerous 
  other 
  economic 
  plants 
  were 
  investigated, 
  

   and 
  propagating 
  material 
  of 
  the 
  most 
  promising 
  was 
  sent 
  to 
  Washington. 
  

   In 
  Guatemala 
  a 
  thousand 
  plants 
  were 
  obtained 
  of 
  the 
  pacayito, 
  a 
  handsome 
  

   dwarf 
  Chamaedorea 
  suitable 
  for 
  house 
  culture; 
  seeds 
  and 
  plants 
  of 
  several 
  

   wild 
  blackberries

  as 
  well 
  as 
  seeds 
  of 
  the 
  handsome 
  Dahlia 
  

   maxonii 
  and 
  other 
  plants. 
  

  

  In 
  Costa 
  Rica 
  a 
  particular 
  study 
  was 
  made 
  of 
  the 
  pejihaye 
  palm 
  {Guilielma 
  

   utilis) 
  , 
  and 
  a 
  quantity 
  of 
  seeds 
  was 
  secured 
  ; 
  seeds 
  of 
  several 
  interesting 
  species 
  

   of 
  Rubus, 
  and 
  other 
  plants, 
  were 
  likewise 
  sent 
  to 
  Washington. 
  

  

  In 
  Colombia 
  many 
  interesting 
  and 
  little-known 
  plants 
  were 
  studied. 
  Per- 
  

   haps 
  the 
  most 
  striking 
  is 
  Rubus 
  macrocarpus, 
  the 
  giant 
  Colombian 
  Berry, 
  

   of 
  which 
  plants 
  were

  Washington. 
  

  

  From

  wild 
  

   form; 
  a 
  cultivated 
  variety 
  of 
  Fragaria 
  chiloensis;

  Louis 
  C. 
  C. 
  Krieger: 
  A 
  sketch 
  of 
  the 
  history 
  of 
  mycological 
  illustration 
  

   {Higher 
  Fungi). 
  

  

  The 
  development 
  of 
  the 
  methods 
  employed 
  in 
  mycological 
  illustrating 
  was 
  

   traced 
  from 
  the 
  time 
  of 
  Clusius 
  (1601) 
  to 
  Boudier 
  (1910). 
  It 
  was 
  pointed 
  out 
  

   that 
  truthful 
  illustrations 
  add 
  much 
  to 
  the 
  completeness 
  of 
  the 
  record 
  of 
  so 
  

   perishable 
  a 
  plant 
  as 
  a 
  fleshy 
  fungus. 
  

  

  Clusius 
  was 
  taken 
  as 
  the 
  starting-point 
  of 
  the 
  historical 
  sketch 
  for 
  the 
  reason 
  

   that 
  his 
  illustrations 
  (especially 
  the 
  original 
  water-colors 
  from 
  which 
  the 
  

   wood-cuts 
  in 
  Clusius' 
  work 
  were 
  made, 
  which 
  have 
  recently 
  been 
  published 
  

   by 
  Istvanffi) 
  are 
  the 
  first 
  truthful 
  figures 
  available 
  to 
  the 
  mycological 
  sys- 
  

   tematist, 
  those 
  of 
  the 
  herbalists, 
  prior 
  to 
  Clusius, 
  often 
  showing 
  fanciful 
  

   embellishments. 
  

  

  The 
  gradual 
  development 
  of 
  the 
  technical 
  processes, 
  from 
  wood-engraving 
  

   through 
  copper-engraving, 
  lithography, 
  half-tone, 
  heliogravure, 
  and 
  tri- 
  

   color 
  printing, 
  was 
  described 
  by 
  the 
  speaker, 
  illustrations 
  from 
  the 
  classic 
  

   works 
  of 
  Schaeffer, 
  Bulliard, 
  Letellier, 
  Sowerby, 
  Greville, 
  Fries, 
  Tulasne, 
  

   and 
  Boudier, 
  serving 
  as 
  examples 
  of 
  the 
  progress 
  in 
  technique. 
  

  

  In 
  concluding 
  his 
  remarks, 
  Mr. 
  Krieger 
  spoke 
  of 
  the 
  dearth 
  of 
  published 
  

   colored 
  illustrations 
  of 
  American 
  origin, 
  and 
  the 
  hope 
  was 
  expressed 
  that 
  

   Dr. 
  Howard 
  A. 
  Kelly, 
  of 
  Baltimore 
  (with 
  whom 
  Mr. 
  Krieger 
  is 
  associated 
  in 
  

   mycological 
  work) 
  might 
  succeed 
  in 
  publishing 
  an 
  illustrated 
  revision 
  of 
  the 
  

   late 
  Prof. 
  Peck's 
  monographs. 
  

  

  This 
  paper, 
  with 
  suitable 
  illustrations, 
  is 
  to 
  be 
  published 
  elsewhere 
  in 
  full 
  

   The 
  address 
  was 
  illustrated 
  by 
  lantern 
  slides 
  as 
  well 
  as 
  by 
  copies 
  of 
  several 
  

   rare 
  mycological 
  books, 
  and 
  by 
  a 
  score 
  or 
  more 
  of 
  Mr. 
  Krieger' 
  s 
  own 
  artistic 
  

   studies 
  of 
  some 
  of 
  the 
  higher 
  fungi.
