  there 
  can 
  be 
  no 
  question 
  that 
  London, 
  having 
  adopted 
  the 
  water-gravitation 
  

   system 
  for 
  cleansing 
  its 
  precincts, 
  within 
  practical 
  distance, 
  no 
  sites 
  could 
  

   have 
  been 
  better 
  chosen 
  for 
  the 
  outfalls 
  than 
  Barking 
  Creek 
  and 
  Crossness, 
  

   as 
  here 
  the 
  country 
  around 
  is 
  devoid 
  of 
  population, 
  hence 
  the 
  works, 
  if 
  not 
  

   altogether 
  inoffensive, 
  are 
  placed 
  where 
  they 
  are 
  in 
  a 
  position 
  to 
  give 
  least 
  

   offence. 
  

  

  Having 
  thus 
  discussed 
  the 
  Home 
  sewage 
  question 
  in 
  its 
  various 
  pliases, 
  

   and 
  noticed 
  the 
  opinions 
  drawn 
  from 
  experimental 
  enquiry, 
  as 
  well 
  as 
  from 
  

   long 
  experience, 
  we 
  will 
  now 
  turn 
  to 
  the 
  subject 
  as 
  it 
  presents 
  itself 
  in 
  this 
  

   Colony. 
  Eeferring 
  to 
  the 
  report 
  published 
  by 
  the 
  Sanitary 
  Commission 
  of 
  

   Dunedin, 
  dated 
  25th 
  January, 
  1865, 
  we 
  find 
  this 
  town 
  principally 
  built 
  of 
  

   wood, 
  at 
  that 
  time 
  containing 
  15,037 
  inhabitants, 
  and 
  whose 
  bad 
  sanitary 
  

   state 
  was 
  graphically 
  described 
  by 
  the 
  city 
  engineer, 
  the 
  late 
  John 
  Millar, 
  

   Esq., 
  F.S.A. 
  

  

  The 
  remedies 
  submitted 
  to 
  the 
  Commission 
  by 
  several 
  engineers 
  were 
  as 
  

   follows 
  : 
  — 
  One 
  assumed, 
  as 
  a 
  matter 
  of 
  course, 
  that 
  the 
  sewage 
  would 
  be 
  

   "hurried 
  into 
  the 
  harbour," 
  though 
  ultimately 
  the 
  outfall 
  might 
  be 
  on 
  to 
  the 
  

   ocean 
  beach. 
  Another 
  propounded 
  a 
  scheme 
  of 
  irrigation, 
  conducting 
  the 
  

   sewage 
  over 
  or 
  through 
  two 
  dividing 
  ranges 
  to 
  the 
  land 
  between 
  Dunedin 
  

   and 
  Saddle 
  Hill, 
  and 
  in 
  which 
  the 
  Taieri 
  Plain 
  might 
  participate. 
  This 
  

   was 
  to 
  be 
  effected 
  by 
  a 
  series 
  of 
  pumping 
  engines. 
  Another 
  suggested 
  

   that 
  the 
  sewage 
  should 
  be 
  discharged 
  at 
  the 
  Lawyers' 
  Head, 
  by 
  means 
  of 
  

   hydraulic 
  pressure 
  on 
  the 
  drains. 
  Another 
  scheme 
  was 
  to 
  submit 
  the 
  

   Forbury 
  Flat 
  to 
  a 
  system 
  of 
  high-class 
  farming 
  by 
  the 
  application 
  of 
  liquid 
  

   sewage. 
  

  

  From 
  this 
  it 
  may 
  be 
  surmised 
  that 
  there 
  was 
  great 
  diversity 
  of 
  opinion 
  

   amongst 
  engineers 
  as 
  to 
  the 
  proposed 
  measures 
  ; 
  but 
  in 
  saying 
  this, 
  it 
  cannot 
  

   be 
  said 
  to 
  be 
  more 
  so 
  than 
  is 
  or 
  was 
  existent 
  amongst 
  engineers 
  in 
  England 
  

   at 
  that 
  date. 
  The 
  fact 
  of 
  the 
  matter 
  is, 
  the 
  subject 
  is 
  a 
  growing 
  one, 
  in 
  

   which 
  time 
  makes 
  changes, 
  and 
  matured 
  experience, 
  we 
  have 
  seen, 
  has 
  

   suggested 
  alterations. 
  

  

  In 
  this 
  case 
  of 
  Dunedin, 
  we 
  see 
  one 
  engineer 
  proposing 
  to 
  direct 
  a 
  

   system 
  of 
  irrigation 
  over 
  a 
  plain, 
  which 
  ten 
  short 
  years 
  have 
  converted 
  into 
  a 
  

   town. 
  Another 
  proposes 
  to 
  fertihze, 
  by 
  a 
  similar 
  scheme, 
  an 
  agricultural 
  

   district, 
  separated 
  from 
  the 
  town 
  by 
  two 
  ranges 
  of 
  hills, 
  at 
  ten 
  miles 
  

   distance, 
  a 
  project 
  worthy 
  of 
  the 
  greatest 
  cities 
  in 
  Europe, 
  and 
  only 
  prac- 
  

   ticable 
  to 
  them. 
  Another 
  proposes 
  to 
  send 
  it 
  into 
  the 
  sea 
  ; 
  another 
  into 
  the 
  

   harbour. 
  It 
  is 
  worthy 
  of 
  note 
  that 
  none 
  proposed 
  a 
  dry 
  system 
  of 
  

   treatment. 
  

  

  Now 
  it 
  would 
  be 
  wrong 
  to 
  infer, 
  from 
  the 
  want 
  of 
  unanimity 
  in 
  the 
  

   engineers, 
  that 
  they 
  were 
  incompetent 
  professionally. 
  On 
  the 
  contrary,
