  Investigations 
  upon 
  living 
  organisms 
  will 
  at 
  first 
  be 
  confined 
  to 
  the 
  

   growth 
  of 
  plants 
  under 
  rigidly 
  controlled 
  physical 
  and 
  chemical 
  

   conditions, 
  the 
  control 
  extending 
  to 
  soil, 
  gases, 
  temperature, 
  humid- 
  

   ity, 
  and 
  intensity 
  and 
  color 
  of 
  light. 
  General 
  biological 
  problems 
  

   will 
  be 
  attacked 
  through 
  spectroscopic 
  investigations 
  of 
  the 
  compli- 
  

   cated 
  molecules 
  which 
  are 
  a 
  part 
  of 
  living 
  organisms 
  ; 
  that 
  is, 
  a 
  study 
  

   of 
  the 
  radiation 
  arising 
  from 
  the 
  internal 
  vibrations 
  of 
  the 
  molecules 
  

   themselves. 
  The 
  work 
  will 
  be 
  done 
  in 
  close 
  cooperation 
  with 
  the 
  

   Fixed 
  Nitrogen 
  Laboratory 
  of 
  the 
  Department 
  of 
  Agriculture, 
  as 
  

   well 
  as 
  with 
  men 
  of 
  diverse 
  training 
  in 
  the 
  biological 
  sciences, 
  so 
  that 
  

   modern 
  specialization 
  may 
  be 
  taken 
  advantage 
  of 
  in 
  these 
  studies 
  on 
  

   the 
  border 
  line 
  of 
  several 
  sciences. 
  

  

  EXPLORATIONS 
  AND 
  FIELD 
  WORK 
  

  

  The 
  field 
  expeditions 
  sent 
  out 
  under 
  the 
  administration 
  or 
  coopera- 
  

   tion 
  of 
  the 
  Institution 
  as 
  an 
  important 
  part 
  of 
  its 
  program 
  in 
  the 
  

   increase 
  of 
  knowledge 
  numbered 
  29 
  during 
  the 
  year. 
  They 
  pertained 
  

   chiefly 
  to 
  anthropology, 
  geology, 
  biology, 
  and 
  astrophysics, 
  and 
  many 
  

   thousands 
  of 
  specimens 
  and 
  much 
  valuable 
  information 
  resulted 
  from 
  

   them. 
  Preliminary 
  illustrated 
  accounts 
  of 
  the 
  work 
  appeared 
  in 
  the 
  

   annual 
  exploration 
  'pamphlet 
  issued 
  by 
  the 
  Institution, 
  and 
  brief 
  

   notices 
  of 
  many 
  of 
  the 
  expeditions 
  will 
  be 
  found 
  in 
  the 
  reports 
  of 
  

   certain 
  of 
  the 
  bureaus 
  under 
  Smithsonian 
  direction, 
  appended 
  hereto. 
  

   The 
  Institution 
  is 
  able 
  to 
  bear 
  the 
  expense 
  of 
  but 
  a 
  very 
  small 
  propor- 
  

   tion 
  of 
  the 
  explorations, 
  the 
  rest 
  being 
  supported 
  by 
  cooperative 
  ar- 
  

   rangements 
  with 
  other 
  governmental 
  and 
  scientific 
  establishments 
  and 
  

   private 
  individuals. 
  

  

  The 
  year's 
  expeditions 
  visited 
  such 
  widely 
  scattered 
  regions 
  as 
  

   China, 
  Alaska, 
  Canada, 
  Labrador, 
  Haiti, 
  Cuba, 
  Honduras, 
  various 
  

   European 
  countries, 
  the 
  Anglo-Egyptian 
  Sudan, 
  and 
  the 
  Philippines, 
  

   besides 
  15 
  States 
  in 
  this 
  country. 
  Among 
  the 
  more 
  extended 
  expedi- 
  

   tions 
  may 
  be 
  mentioned

  Paul 
  Bartsch's 
  moUuscan 
  work 
  in 
  Cuba 
  ; 
  

   investigations 
  of 
  the 
  ancient 
  Eskimo 
  culture 
  of 
  northwestern 
  Alaska, 
  

   by 
  Dr. 
  A. 
  Hrdlicka 
  and 
  Mr. 
  Henry 
  B. 
  Collins; 
  the 
  joint 
  zoological 
  

   and 
  archeological 
  expedition 
  of 
  Messrs. 
  Miller 
  and 
  Krieger 
  to 
  the 
  

   Dominican 
  Republic 
  and 
  Mr. 
  Arthur 
  J. 
  Poole's 
  exploration 
  of 
  

   Haitian 
  caves;

  zoological 
  collecting 
  of 
  the 
  Rev. 
  David 
  C. 
  

   Graham 
  and

  Freer 
  Gallery's 
  archeological 
  work 
  under 
  Mr. 
  Carl 
  

   W. 
  Bishop 
  in 
  China 
  ; 
  and 
  the 
  botanical 
  explorations 
  in 
  Honduras 
  by 
  

   Mr.

  Standley. 
  

  

  COOPERATIVE 
  ETHNOLOGICAL 
  AND 
  ARCHEOLOGICAL 
  IN\^ESTIGATIONS 
  

  

  As 
  stated 
  in 
  my 
  last 
  report. 
  Congress 
  in 
  1928 
  passed 
  an 
  act 
  au- 
  

   thorizing 
  the 
  appropriation 
  of 
  $20,000 
  for 
  cooperative
