  stamping, 
  finishing, 
  copper 
  bands, 
  shell 
  hoisting, 
  all 
  needing 
  some 
  125 
  calories 
  

   per 
  square 
  metre 
  per 
  hour. 
  

  

  The 
  third 
  group 
  covers 
  gauging 
  and 
  walking 
  and 
  carrying, 
  to 
  which 
  

   160 
  calories 
  per 
  square 
  metre 
  per 
  hour 
  may 
  be 
  allotted. 
  

  

  The 
  fourth 
  and 
  last 
  group 
  contains 
  labouring 
  and 
  cleaning 
  and 
  drying, 
  

   which 
  seem 
  to 
  need 
  180 
  calories 
  per 
  square 
  metre 
  per 
  hour. 
  

  

  In 
  using 
  these 
  provisional 
  figures 
  to 
  assess 
  the 
  energetic 
  requirements 
  of 
  

   the 
  factory 
  operative, 
  we 
  are 
  to 
  remember 
  that 
  the 
  trend 
  of 
  public 
  opinion 
  

   points 
  unmistakably 
  to 
  the 
  conclusion 
  that 
  the 
  industrial 
  day 
  will 
  not 
  for 
  

   women 
  exceed 
  eight 
  hours, 
  and, 
  if 
  so, 
  it 
  would 
  be 
  improper 
  to 
  assume 
  that 
  

   more 
  than 
  a 
  maximum 
  of 
  seven 
  hours 
  would 
  be 
  devoted 
  to 
  physical 
  exertion 
  

   approximating 
  to 
  that 
  measured 
  in 
  our 
  experiments. 
  We 
  accordingly 
  think 
  

   that 
  the 
  work 
  contribution 
  to 
  the 
  daily 
  needs 
  of 
  an 
  average 
  woman 
  in 
  each 
  

   of 
  our 
  classes 
  will 
  be 
  reached 
  if 
  the 
  above 
  approximate 
  values 
  are 
  multiplied 
  

   by 
  the 
  product 
  of 
  7 
  and 
  1*6, 
  the 
  latter 
  being 
  the 
  larger 
  of 
  the 
  two 
  values 
  for 
  

   average 
  body 
  surface 
  put 
  forward 
  in 
  the 
  Food 
  (War) 
  Committee's 
  recent 
  

   memorandum. 
  Our 
  four 
  work 
  quotas 
  are 
  accordingly 
  

  

  1120, 
  1400, 
  1792, 
  2016 
  calories. 
  ' 
  

  

  In 
  the 
  memorandum 
  just 
  cited 
  the 
  allocation 
  for 
  needs 
  outside 
  working- 
  

   hours 
  (including 
  2-40 
  calories 
  for 
  travelling 
  and 
  household 
  work) 
  amount 
  to 
  

   1333 
  calories, 
  to 
  which 
  we 
  must 
  add 
  a 
  further 
  77 
  calories, 
  because 
  the 
  

   Committee 
  envisaged 
  8 
  hours 
  of 
  actual 
  industrial 
  work, 
  while 
  we 
  are 
  con- 
  

   templating 
  only 
  7 
  hours. 
  Hence, 
  the 
  quantity 
  to 
  be 
  added 
  to 
  the 
  work 
  quota 
  

   is 
  1410 
  calories, 
  and 
  the 
  complete 
  energy 
  needs 
  of 
  our 
  four 
  classes 
  are 
  : 
  — 
  

  

  2530, 
  2810, 
  3200, 
  3425 
  calories. 
  

  

  Or, 
  making 
  the 
  customary 
  allowance 
  of 
  10 
  per 
  cent, 
  between 
  net 
  energy 
  and 
  

   food 
  eaten, 
  

  

  2810, 
  3120, 
  3555, 
  3805 
  calories. 
  

  

  In 
  comparison 
  with 
  the 
  results 
  deduced 
  by 
  the 
  Committee 
  from 
  Becker 
  

   and 
  Hamalainen's 
  figures 
  our 
  highest 
  class 
  makes 
  greater 
  demands 
  than 
  any 
  

   of 
  theirs, 
  our 
  second 
  highest 
  figure 
  being 
  practically 
  the 
  same 
  as 
  that 
  of 
  the 
  

   most 
  strenuously 
  employed 
  women 
  in 
  the 
  other 
  series. 
  While 
  we 
  are 
  very 
  

   far 
  from 
  thinking 
  that 
  our 
  experiments 
  are 
  sufficient 
  to 
  provide 
  a 
  trustworthy 
  

   figure, 
  they 
  are 
  perhaps 
  more 
  representative 
  of 
  the 
  requirements 
  in 
  a 
  class 
  of 
  

   strenuously 
  employed 
  industrial 
  women 
  than 
  those 
  of 
  Becker 
  and 
  Hama- 
  

   lainen. 
  

  

  The 
  unweighted 
  mean 
  of 
  the 
  food 
  requirements 
  is 
  3322 
  calories,
