  on 
  frequently 
  for 
  work 
  relating 
  to 
  war 
  problems 
  assigned 
  by 
  the 
  

   Army 
  and 
  the 
  Navy, 
  or 
  requested 
  by 
  outside 
  agencies 
  engaged 
  in 
  war 
  

   work. 
  It 
  is 
  hoped 
  that 
  with 
  the 
  return 
  to 
  Washington 
  of 
  Mr. 
  Hoover, 
  

   who 
  has 
  been 
  carrying 
  on 
  measures 
  at 
  Tyrone 
  Observatory 
  for 
  2 
  years, 
  

   the 
  solar-constant 
  computations 
  can 
  be 
  pushed 
  along 
  more 
  rapidly 
  

   so 
  as 
  to 
  disclose 
  the 
  remarkable 
  changes 
  of 
  solar 
  radiation 
  expected 
  

   for 
  the 
  years 
  1940 
  onward, 
  as 
  referred 
  to 
  above. 
  

  

  Most 
  of 
  the 
  time 
  of 
  Messrs. 
  Abbot, 
  Aldrich, 
  and 
  Kramer 
  has 
  been 
  

   devoted 
  to 
  problems 
  assigned 
  by 
  the 
  war 
  services 
  on 
  which 
  no 
  report 
  

   can 
  be 
  made 
  at 
  this 
  time.

  DIVISION 
  OF 
  RADIATION 
  AND 
  ORGANISMS 
  

  

  (Report 
  prepared 
  by 
  Dr. 
  Earl 
  S. 
  Johnston, 
  Assistant 
  Director) 
  

  

  The 
  regular 
  research 
  program 
  of 
  the 
  Division 
  was 
  discontinued 
  

   early 
  in 
  August. 
  Since 
  that 
  date 
  practically 
  the 
  entire 
  time 
  of 
  the 
  

   members 
  of 
  the 
  Division 
  has 
  been 
  directed 
  toward 
  solving 
  problems 
  

   relative 
  to 
  the 
  Nation's 
  war 
  activities. 
  By 
  far 
  the 
  largest 
  percentage 
  

   of 
  this 
  work 
  has 
  dealt 
  with 
  problems 
  submitted 
  by 
  the 
  Naval 
  Re- 
  

   search 
  Laboratory. 
  Because 
  of 
  the 
  nature 
  of 
  some 
  of 
  this 
  work, 
  it 
  

   is 
  obvious 
  that 
  a 
  detailed 
  report 
  cannot 
  be 
  submitted 
  at 
  this 
  time. 
  

   The 
  personnel 
  and 
  laboratory 
  equipment 
  of 
  the 
  Division 
  was 
  such 
  

   that 
  adaptation 
  to 
  this 
  new 
  work 
  in 
  physics, 
  chemistry, 
  and 
  biology 
  

   was 
  very 
  readily 
  made. 
  However, 
  the 
  efficiency 
  of 
  the 
  Division 
  as 
  a 
  

   unit 
  has 
  been 
  decreased 
  somewhat 
  through 
  loss 
  of 
  personnel. 
  

  

  At 
  the 
  request 
  of 
  the 
  Annual 
  Review 
  of 
  Biochemistry, 
  a 
  review 
  ar- 
  

   ticle 
  on 
  photosynthesis 
  was 
  prepared 
  last 
  summer 
  by 
  Dr. 
  Johnston 
  of 
  

   the 
  Division 
  and 
  Dr. 
  Jack 
  E. 
  Myers 
  of 
  the 
  University 
  of 
  Texas. 
  This 
  

   paper 
  has 
  now

  Mrs.

   clerk-stenographer
