  All 
  four 
  cadets 
  were 
  obviously 
  distressed 
  during 
  the 
  last 
  half 
  hour, 
  i.e., 
  the 
  work 
  was 
  excessive. 
  

  

  3rd 
  Test: 
  80 
  Ascents 
  (1600

  in 
  eight 
  hours 
  with 
  \

  rest

   hour

  Neither 
  cadet 
  felt 
  tired 
  ; 
  both 
  were 
  quite 
  willing 
  to 
  go 
  on. 
  

  

  The 
  conclusion 
  drawn 
  from 
  these 
  tests 
  was 
  that 
  an 
  average 
  healthy 
  young 
  

   man, 
  fit 
  for 
  military 
  service, 
  can 
  do 
  at 
  least 
  100,000 
  kgrm.-metres 
  per 
  day, 
  and 
  

   that 
  a 
  mechanical 
  task 
  of 
  200,000 
  kgrm.-metres 
  per 
  day 
  is 
  beyond 
  his 
  power. 
  

   I 
  much 
  regret 
  that 
  I 
  did 
  not 
  then 
  possess 
  the 
  simple 
  apparatus 
  necessary 
  for 
  

   keeping 
  the 
  C0 
  2 
  ordinate 
  during 
  these 
  tests, 
  and 
  should 
  be 
  very 
  glad 
  if 
  any 
  

   " 
  healthy 
  young 
  man 
  " 
  would 
  volunteer 
  to 
  repeat 
  the 
  tests 
  with 
  control 
  of 
  

   his 
  G0

  Conclusion. 
  

  

  The 
  Food 
  (War) 
  Committee, 
  in 
  its 
  ' 
  Eeport 
  on 
  the 
  Food 
  Piequirements 
  of 
  

   Man,' 
  March, 
  1919, 
  has 
  proposed 
  the 
  adoption 
  of 
  the 
  following 
  classification 
  

   of 
  manual 
  workers, 
  in 
  conformity 
  with 
  the 
  excess 
  of 
  energy 
  expended 
  during 
  

   eight 
  hours' 
  work 
  over 
  that 
  expended 
  during 
  eight 
  hours 
  of 
  sleep, 
  as 
  follows 
  

   (p. 
  5):-
