  and 
  critical 
  comparisoir 
  of 
  many 
  thousands 
  of 
  specimens 
  of 
  fossil 
  genera 
  and 
  

   species 
  of 
  ancient 
  marine 
  life, 
  and 
  often 
  study 
  of 
  microscopic 
  sections 
  of 
  rocks 
  

   and 
  fossils 
  in 
  the 
  hope 
  of 
  finding 
  evidence 
  of 
  the 
  presence 
  of 
  minute 
  and 
  active 
  

   bacterial 
  and 
  simple 
  algal 
  workers, 
  such 
  as 
  exist 
  in 
  modern 
  seas 
  and 
  lakes, 
  

   which 
  by 
  their 
  united 
  efforts 
  form 
  great 
  masses 
  of 
  the 
  recent 
  sea 
  and 
  lake 
  

   deposits. 
  

  

  These 
  researches 
  in 
  Cambrian 
  geology 
  and 
  paleontology, 
  which 
  

   were 
  continued 
  until 
  his 
  death, 
  constitute 
  his 
  outstanding 
  contribu- 
  

   tion 
  to 
  science 
  and 
  won 
  for 
  him 
  from 
  foreign 
  and 
  American 
  societies 
  

   five 
  medals, 
  including 
  the 
  Wollaston 
  medal, 
  the 
  highest 
  honor 
  at 
  the 
  

   disposal 
  of 
  the 
  Geological 
  Society 
  of 
  London. 
  One 
  of 
  his 
  fellow 
  

   scientists 
  recently 
  estimated 
  that 
  of 
  the 
  sum 
  of 
  existing 
  knowledge 
  

   on 
  those 
  subjects 
  70 
  per 
  cent 
  had 
  been 
  contributed 
  by 
  Doctor 
  Walcott 
  

   and 
  that 
  fully 
  half 
  of 
  his 
  work 
  in 
  this 
  field 
  was 
  done 
  within 
  the 
  last 
  

   20 
  years 
  — 
  a 
  record 
  truly 
  remarkable 
  in 
  view 
  of 
  his 
  diverse 
  activities 
  

   and 
  responsibilities. 
  

  

  His 
  powers 
  of 
  specialization 
  and 
  generalization 
  were 
  equally 
  well 
  

   developed; 
  he 
  discerned 
  every 
  minutest 
  feature 
  of 
  the 
  organisms 
  on 
  

   which 
  he 
  worked, 
  but 
  he 
  was 
  also 
  able 
  " 
  to 
  think 
  in 
  continents," 
  and 
  

   so 
  his 
  studies 
  made 
  large 
  contributions 
  toward 
  unraveling 
  the 
  prob- 
  

   lems 
  of 
  Paleozoic 
  phj^siography. 
  

  

  A 
  scientist 
  by 
  deliberate 
  choice 
  and 
  highly 
  successful 
  in 
  his 
  chosen 
  

   field, 
  Doctor 
  Walcott 
  allowed 
  no 
  talent 
  to 
  remain 
  unused. 
  He 
  had 
  

   the 
  mind 
  of 
  a 
  skilled 
  executive 
  with 
  exceptionally 
  sound 
  business 
  

   sense 
  and 
  of 
  a 
  successful 
  diplomat 
  with 
  marked 
  ability 
  in 
  coordinat- 
  

   ing 
  policies 
  and 
  uniting 
  men. 
  Although 
  at 
  the 
  age 
  of 
  21 
  his 
  proved 
  

   capacity 
  invited 
  a 
  business 
  career 
  and 
  later 
  much 
  more 
  promising 
  

   opportunities 
  came 
  to 
  him, 
  his 
  obvious 
  genius 
  for 
  business 
  was 
  

   turned 
  into 
  channels 
  of 
  public 
  service. 
  

  

  The 
  simple 
  title 
  of 
  his 
  address 
  as 
  retiring 
  president 
  of 
  the 
  Amer- 
  

   ican 
  Association 
  for 
  the 
  Advancement 
  of 
  Science 
  in 
  1924, 
  " 
  Science 
  

   and 
  service," 
  concisely 
  stated 
  his 
  creed 
  ; 
  advancement 
  of 
  science 
  im- 
  

   plies 
  " 
  the 
  physical, 
  mental, 
  and 
  moral 
  advancement 
  of 
  the 
  human 
  

   race," 
  and 
  in 
  his 
  public 
  life 
  this 
  research 
  scientist 
  so 
  applied 
  his 
  

   talents 
  that 
  his 
  public 
  service 
  perhaps 
  overshadowed 
  his 
  science. 
  

  

  Exceptional 
  capacity 
  for 
  the 
  dual 
  duties 
  of 
  research 
  and 
  adminis- 
  

   tration 
  eminently 
  fitted 
  Doctor 
  Yv^alcott 
  for 
  the 
  two 
  official 
  positions 
  

   he 
  held 
  during 
  the 
  third 
  of 
  a 
  century 
  in 
  which 
  he 
  was 
  a 
  prominent 
  

   figure 
  in 
  public 
  life. 
  As 
  Director 
  of 
  the 
  United 
  States 
  Geological 
  

   Survey, 
  1894r-1907, 
  he 
  so 
  administered 
  that 
  scientific 
  bureau, 
  devoted 
  

   to 
  fact 
  finding 
  and 
  the 
  coordination 
  of 
  facts 
  and 
  principles, 
  as 
  to 
  

   serve 
  both 
  the 
  Government 
  and 
  the 
  people. 
  " 
  The 
  public 
  " 
  as 
  defined 
  

   and 
  served 
  by 
  Director 
  Walcott 
  included 
  farmer, 
  miner, 
  landowner, 
  

   and 
  investor 
  as 
  well 
  as 
  student, 
  teacher, 
  and 
  research 
  specialist. 
  He 
  

   was 
  prompt 
  to 
  see 
  the 
  need 
  of 
  research, 
  both 
  scientific 
  and 
  engineer-
