  Leeds 
  has 
  a 
  population 
  of 
  291,580, 
  covering 
  an 
  area 
  of 
  21,572 
  acres. 
  

   But 
  the 
  town 
  at 
  present 
  sewered 
  covers 
  only 
  about 
  4,900 
  acres, 
  with 
  a 
  

   population 
  of 
  245,600, 
  thus 
  showing 
  a 
  population 
  of 
  50 
  to 
  the 
  acre, 
  while 
  

   Glasgow 
  has 
  88*6. 
  The 
  average 
  mortality 
  for 
  the 
  five 
  years 
  — 
  1871 
  to 
  1875 
  

   inclusive 
  — 
  is 
  27'4 
  per 
  1,000. 
  The 
  number 
  of 
  water-closets 
  in 
  Leeds 
  is 
  

   8,500, 
  and 
  of 
  ash-pits 
  and 
  privies 
  13,000, 
  and 
  about 
  3,000 
  of 
  the 
  latter 
  are 
  

   provided 
  with 
  pails 
  or 
  boxes. 
  Many 
  of 
  the 
  privies 
  have 
  been 
  recently 
  

   altered 
  into 
  trough 
  water-closets, 
  which 
  are 
  highly 
  approved 
  by 
  Dr. 
  Goldie, 
  

   the 
  Medical 
  Officer 
  of 
  Health. 
  Originally 
  experimental 
  works 
  were 
  erected 
  

   to 
  test 
  the 
  efficacy 
  of 
  the 
  A, 
  B, 
  C 
  process, 
  which 
  was 
  in 
  the 
  hands 
  of 
  a 
  

   Native 
  Guano 
  Company. 
  These 
  works 
  cost 
  about 
  ^610,000, 
  and 
  were 
  con- 
  

   structed 
  to 
  treat 
  2 
  million 
  gallons 
  of 
  sewage 
  daily. 
  The 
  success 
  of 
  the 
  

   experiment, 
  so 
  far 
  as 
  producing 
  an 
  apparently 
  good 
  effluent, 
  induced 
  the 
  

   Corporation 
  to 
  erect 
  works 
  for 
  the 
  chemical 
  treatment 
  of 
  the 
  entire 
  sewage 
  

   of 
  the 
  town, 
  amounting 
  to 
  nearly 
  14 
  million 
  gallons 
  daily, 
  which 
  cost 
  

   £50,000 
  ; 
  but 
  since 
  the 
  works 
  have 
  been 
  in 
  operation 
  practically, 
  it 
  has 
  

   been 
  found 
  impossible 
  to 
  dispose 
  of 
  the 
  produce 
  in 
  any 
  quantity. 
  As 
  

   regards 
  undried 
  sludge 
  the 
  farmers 
  in 
  the 
  vicinity 
  refuse 
  to 
  accept 
  it 
  as 
  a 
  

  

  gift.

  The 
  works 
  for 
  the 
  purification 
  of 
  the 
  sewage 
  are 
  at 
  

   Manningham, 
  about 
  IJ 
  miles 
  from 
  the 
  town. 
  The 
  sewage 
  amounts 
  on 
  an 
  

   average 
  to 
  9 
  million 
  gallons 
  per 
  day, 
  and 
  the 
  precipitant 
  used 
  is 
  lime. 
  The 
  

   quantity 
  employed 
  is 
  about 
  18 
  cwt. 
  per 
  million 
  gallons 
  of 
  sewage. 
  The 
  

   works 
  cost 
  £65,000, 
  and 
  cost 
  of 
  working 
  £5,000 
  per 
  annum. 
  

  

  Halifax, 
  a 
  town 
  of 
  68,500 
  inhabitants, 
  occupies 
  an 
  area 
  of 
  3,768 
  acres, 
  

   giving 
  a 
  density 
  of 
  population 
  equal

  The

  The 
  town 
  contains 
  2,000 
  water-closets 
  and 
  about 
  

   3,800 
  dry-closets. 
  The 
  sewage 
  amounts 
  to 
  2h 
  millions 
  of 
  gallons 
  (per 
  

   diem), 
  and 
  is 
  carried 
  in 
  a 
  culvert 
  to 
  a 
  small 
  beck 
  or 
  burn, 
  which 
  runs 
  through 
  

   the 
  valley 
  in 
  which 
  the 
  town 
  is 
  situated. 
  Formerly 
  lime 
  was 
  used 
  to 
  

   defecate 
  the 
  sewage, 
  but 
  this 
  attempt 
  at 
  purification 
  has 
  ceased. 
  The 
  Goux 
  

   system 
  is 
  here 
  adopted 
  for 
  the 
  dry-closets. 
  Once 
  worked 
  by 
  a 
  company, 
  

   but 
  at 
  a 
  heavy 
  loss, 
  the 
  Corporation 
  now 
  carry 
  on 
  the 
  works.
