  The

  At

  none

   Ordinarily, 
  in

  ascend 
  to

   point, 
  and 
  rarely 
  a

  This 
  is 
  due

  The 
  "2nd 
  obstruction 
  reported 
  by

   is 
  the

  The

  of 
  

   watei-

  at 
  this 
  dam 
  is 
  only 
  about 
  '2 
  feet. 
  

  

  At 
  Avondale 
  Mills, 
  about 
  one 
  and 
  (»ne-half 
  miles 
  be- 
  

   low 
  Laurel, 
  is 
  a 
  stone 
  dam 
  about 
  live 
  feet 
  high, 
  which 
  is 
  

   the 
  third 
  and 
  last 
  obstiiiction 
  on 
  the 
  river 
  until 
  you 
  

   ascend 
  to 
  the 
  dam 
  of 
  the 
  [jauiel 
  Cotton 
  Mills. 
  

  

  The 
  (him 
  of 
  the 
  Laurel 
  ALUs 
  is 
  built 
  of 
  stone, 
  and 
  is 
  

   about 
  :28 
  feet 
  high. 
  At 
  ordinary 
  summer 
  stages 
  of 
  water, 
  

   there 
  is 
  no 
  discharge 
  of 
  water 
  over 
  the 
  dam. 
  The 
  whole 
  

   stream 
  is 
  diverted 
  to 
  furnish 
  nu)tive 
  power 
  to 
  the 
  cotton 
  

   mills, 
  and 
  at 
  very 
  low 
  stages 
  of

  this 
  is

  The 
  river 
  may 
  be 
  opened 
  to 
  the 
  Laurel 
  Mills 
  so 
  as 
  to 
  

   permit 
  free 
  passage 
  of 
  fish 
  with 
  comparatively 
  little 
  

   trouble 
  and 
  at 
  a 
  very 
  niodei-ate 
  ex[)ense. 
  

  

  Below 
  this 
  ]K)int 
  the 
  supply 
  of 
  water 
  is 
  considerably 
  

   in 
  excess 
  of 
  the 
  aniount 
  used 
  for 
  motive 
  i)ower, 
  and 
  a 
  

   sufficient 
  quantity 
  of 
  water 
  may 
  be 
  discharged 
  through 
  

   the 
  fisliways 
  to 
  invite 
  the 
  ascent 
  of 
  shad, 
  which 
  are 
  a 
  

   timorous 
  fish, 
  and 
  indisposed 
  to 
  enter 
  a 
  way 
  discharging 
  

   an 
  inconsiderable 
  volume 
  of
