  have 
  the 
  Gunpowder 
  Eiver, 
  wliich 
  is 
  obstructed 
  by 
  a 
  dam 
  

   of 
  recent 
  construction, 
  a 
  part 
  of 
  tlie 
  system 
  foi- 
  supplying 
  

   the 
  city 
  of 
  Baltimore' 
  with 
  water. 
  This 
  and 
  otlier 
  minor 
  

   obstructions 
  should 
  be 
  provided 
  with 
  iishways, 
  and 
  if 
  

   the 
  shad, 
  lierring 
  and 
  i-ock 
  weretlius 
  alh)wed 
  free 
  access 
  

   to 
  the 
  upper 
  waters 
  of 
  the 
  river, 
  tlie 
  fisheries 
  below 
  the 
  

   dam 
  and 
  at 
  the 
  mouth 
  of 
  this 
  stream 
  would 
  soon 
  be 
  

   vastly 
  improved. 
  

  

  The 
  Patapsco 
  River 
  is 
  also 
  obstructed 
  by 
  many 
  dams, 
  

   none 
  of 
  which 
  have 
  been 
  provided 
  with 
  effective 
  Iishways, 
  

   although 
  they 
  are 
  especially 
  required 
  ))y 
  law. 
  

  

  In 
  order 
  to 
  illustrate 
  the 
  practicability 
  of 
  restoring 
  

   the 
  shad, 
  herring 
  and 
  rock 
  to 
  waters 
  in 
  which 
  they 
  

   were 
  formerl}- 
  abundant, 
  but 
  where 
  they 
  have 
  since 
  

   become 
  unknown, 
  I 
  requested 
  Col. 
  Marshall 
  McDonald, 
  

   the 
  Commissioner 
  of 
  Fisheries 
  of 
  the 
  State 
  of 
  Virginia, 
  

   who 
  had 
  made 
  the 
  construction 
  of 
  tishways 
  a 
  specialty, 
  

   to 
  examine 
  the 
  Patuxent 
  River 
  and 
  advise 
  me 
  as 
  to 
  what 
  

   could 
  be 
  done 
  on 
  this 
  stream. 
  

  

  If 
  the 
  shad 
  could 
  be 
  brought 
  back 
  in 
  numbers 
  to 
  Lau- 
  

   rel, 
  after 
  having 
  disap}teared 
  from 
  the 
  river 
  for 
  years, 
  

   the 
  citizens 
  of 
  Maryland 
  would 
  be 
  satisfied 
  as 
  to 
  the 
  good 
  

   that 
  would 
  be 
  accomplished 
  by 
  the 
  erection 
  of 
  tishways 
  

   over 
  all 
  of 
  the 
  artihcial 
  obstructions 
  in 
  the 
  State. 
  

  

  That 
  many 
  miles 
  of 
  the 
  Patuxent 
  River, 
  at 
  least, 
  can 
  

   be 
  opened 
  to 
  the 
  migration 
  of 
  these 
  valuable 
  fishes, 
  will 
  

   be 
  seen 
  by 
  the 
  following 
  report 
  made 
  as 
  the 
  result 
  of 
  the 
  

   examinations 
  of 
  that 
  river: 
  

  

  Obstructions 
  to
