  The 
  work 
  of 
  tlie 
  United 
  States 
  Commission 
  of 
  Fish 
  and 
  Fisheries 
  

   is 
  carried 
  on 
  at 
  twenty-five 
  stations 
  or 
  hatcheries 
  located 
  at 
  suitable 
  

   places 
  throui?hout 
  the 
  country. 
  At 
  Woods 
  Hole 
  and

  Massa- 
  

   chusetts, 
  cod, 
  mackerel, 
  lobster, 
  and 
  other 
  imi)ortant 
  marine 
  species 
  are 
  

   propagated 
  and 
  the 
  fry 
  are 
  deposited 
  on 
  the 
  natural 
  spawning-grounds 
  

   along 
  the 
  coast. 
  At 
  Battle 
  Creek, 
  Baird, 
  and 
  Hoopa 
  Valley 
  in 
  Califor- 
  

   nia,

  River 
  in 
  Wash- 
  

   ington, 
  the 
  eggs 
  of 
  the 
  Pacific 
  salmon 
  are 
  collected 
  and 
  hatched, 
  and 
  

   the 
  fry 
  are 
  planted 
  on 
  tlie 
  spawning-beds 
  in 
  the 
  neighboring 
  streams. 
  

   The 
  Atlantic 
  and 
  landlocked 
  salmons 
  are 
  cultivated 
  in 
  Maine 
  at 
  Craig 
  

   Brook 
  and 
  Green 
  Lake 
  to 
  restock 
  the 
  depleted 
  streams 
  and 
  lakes 
  of 
  

   New 
  England 
  and 
  northern 
  New 
  York. 
  On 
  the 
  Great 
  Lakes 
  at 
  Cape 
  

   Vincent, 
  New 
  York 
  ; 
  Put-in 
  Bay, 
  Ohio; 
  Alpena, 
  Michigan, 
  and 
  Duluth, 
  

   Minnesota, 
  the 
  work 
  is 
  with 
  whitefish 
  and 
  lake 
  trout, 
  in 
  order 
  to 
  sustain 
  

   the 
  great 
  commercial 
  fisheries 
  conducted 
  for 
  those 
  species. 
  Hatcheries 
  

   in 
  the 
  interior 
  at 
  St. 
  Johnsbury, 
  Vermont; 
  Wytheville, 
  Virginia; 
  

   North

  Bozeman, 
  Montana; 
  Neosho, 
  

   Missouri; 
  Quincy, 
  Ilhnois; 
  San 
  Marcos, 
  Texas, 
  and 
  Leadville, 
  Colo- 
  

   rado, 
  are 
  devoted 
  to 
  the 
  important 
  work 
  of 
  maintaining 
  in 
  the 
  inland 
  

   lakes 
  and 
  streams 
  the 
  supply 
  of 
  brook 
  trout, 
  rainbow 
  trout, 
  black 
  bass, 
  

   crappie, 
  and 
  other 
  fishes. 
  During 
  the 
  spring, 
  on 
  the 
  Potomac, 
  Dela- 
  

   ware, 
  and 
  Susquehanna 
  rivers, 
  shad 
  are 
  hatched 
  and 
  are 
  distributed 
  

   in 
  suitable 
  streams 
  along 
  the 
  Atlantic 
  Coast. 
  

  

  For 
  the 
  distribution 
  of 
  fish 
  and 
  eggs 
  the 
  Commission 
  has 
  four 
  cars 
  

   specially 
  equipped 
  with 
  tanks, 
  air-circulating 
  apparatus, 
  and 
  other 
  

   appliances. 
  

  

  In 
  the 
  prosecution 
  of 
  marine 
  work 
  three 
  vessels 
  are 
  used, 
  the 
  steamers 
  

   Albatross 
  and 
  Fish 
  Ha 
  ivic, 
  and 
  a 
  schooner, 
  the 
  Grampus. 
  The 
  Albatross 
  

   is 
  fitted 
  with 
  appliances 
  for 
  deep-sea 
  dredging 
  and 
  collecting 
  work, 
  and 
  

   is 
  used 
  for 
  surveying 
  and 
  exploring 
  ocean 
  bottoms 
  and 
  investigating 
  

   marine 
  life. 
  The 
  Fish 
  HawTi 
  is 
  in 
  reality 
  a 
  floating 
  hatchery, 
  and 
  is 
  

   engaged 
  in 
  hatching 
  shad, 
  lobsters, 
  and 
  mackerel, 
  in 
  collecting 
  eggs, 
  

   and 
  in 
  distributing 
  fry, 
  besides 
  making 
  topographic 
  surveys 
  of 
  fishing- 
  

   grounds, 
  etc. 
  

  

  The 
  necessity 
  for 
  a 
  handbook 
  describing 
  the 
  manner 
  of 
  propagating 
  

   the 
  different 
  fishes 
  reared 
  by 
  the 
  United 
  States 
  Commission 
  of 
  Fish 
  

   and 
  Fisheries 
  has 
  long 
  been 
  felt 
  in 
  the 
  Commission, 
  and 
  it 
  is
