  The 
  dredge 
  has 
  a 
  continuous 
  shoe 
  or 
  runner 
  ranging 
  along 
  the 
  rake- 
  

   head 
  or 
  bar, 
  to 
  which 
  the 
  rake-teeth 
  are 
  fastened. 
  This 
  runner 
  lies 
  

   obliquely 
  with 
  its 
  forward 
  edge 
  about 
  in 
  line 
  with 
  the 
  point 
  of 
  projec- 
  

   tion 
  of 
  the 
  teeth 
  from 
  the 
  rake-head, 
  so 
  that 
  while 
  the 
  teeth 
  will 
  enter 
  

   the 
  river 
  bottom 
  their 
  entire 
  projecting 
  length, 
  the 
  dredge 
  will 
  be 
  pre- 
  

   vented 
  from 
  sinking 
  further 
  into 
  the 
  soft 
  bottom. 
  The 
  runner 
  also 
  

   serves 
  to 
  smooth 
  the 
  bottom 
  to 
  leave 
  it 
  in 
  better 
  condition 
  for 
  the 
  sub- 
  

   sequent 
  planting 
  and 
  growth 
  of 
  the 
  shell-fish. 
  The 
  rake-head 
  is 
  fitted 
  

   with 
  a 
  trailing 
  basket, 
  which 
  receives 
  the 
  oysters 
  as 
  they 
  are 
  removed 
  

   by 
  the 
  rake 
  teeth.
