  "The 
  hatchery 
  at 
  Northville, 
  Michigan, 
  under 
  the 
  

   direction 
  of 
  Mr. 
  Frank

  passed 
  into 
  the 
  hands 
  of 
  

   the 
  United 
  States 
  Fish 
  Commission 
  in 
  1880, 
  and 
  is 
  now- 
  

   one 
  of 
  the 
  most 
  important 
  stations 
  for 
  salmonidse 
  in 
  the 
  

   world. 
  It 
  is 
  provided 
  with 
  natural 
  and 
  artificial 
  ponds 
  in 
  

   which 
  brook-trout, 
  rainbow-trout, 
  land-locked 
  salmon 
  and 
  

   lake-trout, 
  are 
  kept 
  for 
  breeding 
  purposes. 
  In 
  addition 
  to 
  

   the 
  eggs 
  obtained 
  from 
  these 
  ponds, 
  many 
  millions 
  of 
  eggs 
  

   of 
  the 
  white-fish, 
  lake-trout, 
  and 
  wall-eyed 
  pike 
  are 
  

   obtained 
  in 
  the 
  waters 
  of 
  Lake 
  Erie, 
  and 
  forwarded 
  to 
  

   Northville 
  to 
  be 
  hatched 
  and 
  distributed. 
  During 
  the 
  

   season 
  of 
  1882-3, 
  70,950,000 
  eggs 
  of 
  the 
  salmonidse 
  were 
  

   handled 
  at 
  this 
  hatchery, 
  a 
  large 
  percentage 
  of 
  which 
  were 
  

   hatched 
  and 
  distributed 
  to 
  different 
  waters. 
  A 
  large 
  

   refrigerator 
  is 
  being 
  put 
  in 
  in 
  readiness 
  for 
  next 
  season's 
  

   work, 
  when 
  it 
  is 
  expected 
  that 
  fully 
  500,000,000 
  eggs 
  of 
  

   the 
  white-fish 
  alone 
  will 
  be 
  hatched.
