The  8th  Chapter  of  this  Treatise'displays  nqtpnto
the  immepse  importance  of  controlling  theevil  hatyt*
pf  aquatic  labourers  and  others  on  the  River  Thames
and  in  the  Vjj^rchouses  adjacent ;  but  also  the  ad:
vantages  to  be  expected  from  a  general  Polk$
System;  reasoning  on  the  extensive  success  which
has  attended  the,  partial  experiment  on  the  sanic
principle  of  vigilance  applied  to  this  object.'

The  extensive  benefits  which  are  known  and
acknowledged  to  have  been  derived  from  the  Marine
Police  (even  under  all  thedisadvantagesof  a  Crippled
System  and  JD^/wenl  Powers)  joined  to  a  review  of
the  state  of  the  River  before  and  since  this  important
measure  was  adopted,  afford  the  best  proof  that  can
be  adduced  r5f  its  utility  j  and  atao  of  the  indispensable

necessity,

maneiicy  to  this  important  Establishment,  in  oidet
to  secure  to  the  Commerce  and  Revenue  of  the  River
Thames,  those  advantaged  which  will  arise  from  the
l*reservatidn  of  Property  against  the  numerous  and
tinetadipled  Depredations  to  which  it  was  exposed ;
and  the  Revenue  of  the  Crown  frou>  many  frauds
which  arose  not  only  from  the  Joss  of  th^- Duties  of
Customs  and  Excise  on  goods  plundered,  but  also
from  an  extensive  illicit  trade!  which  has  been  con-
trolled and  prevented  by  the  known  vigilafcc.e  df

If  to  those  advantages  shall  be  added  an  increase
of  Salaries  to  the  inferior  Officers  qf  the  Cuftoms  and

ment of  the  Country.    Every  individual  concerned
