  inated 
  water 
  supplies, 
  discontinuing 
  the 
  use 
  of 
  Hudson 
  and 
  

   Mohawk 
  rivers 
  therefor, 
  and 
  reserving 
  them 
  instead 
  for 
  sewage 
  

   disposal. 
  This 
  proposition 
  is 
  equally 
  true 
  as 
  regards 
  the 
  other 
  

   principal 
  rivers 
  of 
  the 
  State. 
  

  

  The 
  foregoing 
  indicates 
  that 
  pure 
  water 
  supply 
  and 
  sewage 
  dis- 
  

   posal 
  must 
  go 
  together 
  — 
  that 
  they 
  are 
  of 
  equal 
  importance 
  and 
  

   neither 
  can 
  be 
  neglected. 
  To 
  accomplish 
  these 
  objects, 
  a 
  per- 
  

   manent 
  State 
  water 
  supply 
  and 
  sewage 
  disposal 
  commission 
  

   should 
  be 
  created 
  at 
  some 
  time 
  in 
  the 
  future. 
  This 
  commission 
  

   would 
  work 
  substantially 
  on 
  the 
  lines 
  laid 
  down 
  by 
  the 
  several 
  

   English 
  commissions, 
  who 
  have 
  considered 
  questions 
  of 
  water 
  

   supply 
  and 
  sewage 
  disposal 
  for 
  the 
  last 
  40 
  to 
  50 
  years.

  Before 
  the 
  work 
  of 
  such 
  a 
  commission 
  can 
  be 
  effective, 
  it 
  is 
  

   necessary 
  that 
  a 
  new 
  topographical 
  map 
  of 
  the 
  State 
  be 
  made 
  

   at 
  a 
  scale 
  not 
  smaller 
  than

  The 
  work 
  of 
  the 
  English 
  com- 
  

   missions 
  has 
  been 
  specially 
  effective 
  because 
  of 
  having 
  the 
  Ordi- 
  

   nance 
  Map 
  of 
  Great 
  Britain 
  at 
  a 
  considerably 
  larger 
  scale 
  than 
  

   r5To"o-o 
  • 
  The 
  area 
  included 
  in 
  the 
  several 
  water 
  centers 
  should 
  be 
  

   undertaken 
  first 
  and 
  will 
  occuy 
  from 
  10 
  to 
  15 
  years. 
  After 
  this 
  

   map 
  is 
  well 
  advanced, 
  such 
  a 
  commission 
  could 
  be 
  properly 
  

   appointed. 
  

  

  In 
  reference 
  to 
  the 
  present 
  topographical 
  map 
  of 
  the 
  State, 
  it 
  is 
  

   at 
  too 
  small 
  a 
  scale 
  (g^wo 
  ) 
  to 
  be 
  of 
  use 
  other 
  than 
  as 
  a 
  general 
  

   guide. 
  The 
  definition 
  of 
  the 
  several 
  water 
  areas 
  will 
  require 
  more 
  

   precision 
  than 
  is 
  possible 
  on 
  a 
  map 
  of 
  the 
  scale 
  of 
  the 
  present 
  

   topographical 
  map. 
  

  

  The 
  writer 
  will 
  indicate 
  some 
  of 
  the 
  duties 
  which 
  may 
  be 
  likely 
  

   to 
  fall 
  upon 
  such 
  a 
  commission 
  as 
  is 
  here 
  suggested, 
  drawing 
  some- 
  

   what 
  upon 
  an 
  act 
  proposed 
  a 
  few 
  years 
  ago 
  in 
  Xew 
  Jersey, 
  largely 
  

   the 
  work 
  of 
  the 
  late 
  Lebbeus 
  B.

  of 
  Jersey

  a

  the 
  commissioners 
  would

  define
