  — 
  This 
  report 
  has 
  

   much 
  more 
  than 
  a 
  local 
  value, 
  since 
  the 
  subject 
  with 
  which 
  it 
  

   deals 
  is 
  of 
  vital 
  importance 
  to 
  all 
  communities 
  situated 
  on 
  the 
  

   banks 
  of 
  any 
  one 
  of 
  our 
  great 
  rivers. 
  The 
  whole 
  subject 
  of 
  

   stream 
  pollution 
  in 
  its 
  various 
  aspects 
  is 
  taken 
  up 
  in 
  detail, 
  and 
  

   much 
  information 
  is 
  given 
  as 
  to 
  the 
  analytical 
  work 
  done, 
  with 
  

   special 
  details 
  as 
  to 
  individual 
  localities.
