  This 
  cove 
  is 
  located 
  on 
  tlie 
  novtli 
  sliove 
  of 
  King 
  George 
  Bag. 
  

   It 
  is 
  very 
  secure 
  and 
  narrow, 
  but 
  tlie 
  water 
  is 
  fairly 
  deep, 
  

   ranging 
  from 
  8 
  fms. 
  at 
  its 
  month 
  to 
  'nil' 
  at 
  its 
  upper 
  

   extremity, 
  and 
  it 
  measures 
  about 
  a 
  mile 
  and 
  a 
  half 
  in 
  

   length. 
  

  

  " 
  The 
  bottom 
  varies 
  from 
  fine 
  shingle 
  and 
  sand 
  for 
  about 
  the 
  

   first 
  three 
  hundred 
  yards, 
  this 
  being 
  scoured 
  by 
  sheltered 
  

   estuaries, 
  eiTectually 
  preventing 
  any 
  work 
  being 
  done 
  on 
  the 
  

   water, 
  so 
  shore-collecting 
  was 
  the 
  main 
  chance 
  and 
  also 
  

   close 
  examination 
  of 
  many 
  freshwater 
  pools 
  near, 
  especially 
  

   the 
  large 
  freshwater 
  lake 
  at 
  the 
  head 
  of 
  Byron 
  Sound. 
  

  

  " 
  Within 
  tidal 
  limits, 
  by 
  far 
  the 
  best 
  collecting-ground 
  was 
  

   to 
  the 
  north-east 
  of 
  Rapid 
  Point, 
  Port 
  Egremont. 
  Here 
  an 
  

   eddy 
  or 
  back-water 
  was 
  formed, 
  and, 
  owing 
  to 
  the 
  abundance 
  

   of 
  large 
  flat 
  shale 
  rocks 
  of 
  varying 
  sizes, 
  some 
  excellent 
  

   collecting 
  could 
  be 
  done.
