  ash, 
  the 
  result 
  of 
  the 
  Katmai 
  eruption 
  of 
  1912, 
  

  

  and 
  as 
  a 
  result 
  successful 
  hatchery 
  operations 
  on 
  an 
  appropriate 
  scale 
  

  

  are 
  practically 
  impossible, 
  or 
  at 
  least 
  appear 
  to 
  be 
  until 
  such 
  time 
  

  

  as 
  the 
  ashes 
  have 
  become 
  incorporated 
  with 
  soil 
  and

  Uganik 
  Lake. 
  

  

  Experimental 
  hatchery 
  operations 
  were 
  also 
  conducted 
  this 
  season 
  

   as 
  an 
  adjunct 
  to 
  the 
  Afognak 
  work 
  at 
  Uganik 
  Lake, 
  wliich 
  place 
  is 
  

   about 
  40 
  miles 
  from 
  Afognak. 
  

  

  At 
  the 
  beginning 
  of 
  the 
  season 
  a 
  barrier 
  was 
  put 
  across 
  the 
  river 
  

   between 
  the 
  lake 
  and 
  the 
  bay 
  in 
  an 
  ejffort 
  to 
  get 
  an 
  accurate 
  count 
  of 
  

   the 
  fish 
  entering 
  the 
  lake, 
  but 
  on 
  account 
  of 
  swift 
  current 
  and 
  for 
  

   other 
  reasons 
  it 
  was 
  impossible 
  to 
  maintain 
  the 
  barrier. 
  During 
  the 
  

   period 
  from 
  August 
  7 
  to 
  September 
  8 
  a 
  total 
  of 
  1,970,000 
  sockeye 
  

   eggs 
  were 
  taken 
  and 
  placed 
  in 
  temporary 
  hatching 
  troughs. 
  With 
  

   the 
  approach 
  of 
  cold 
  weather, 
  when 
  the 
  eggs 
  were 
  well 
  eyed, 
  they 
  

   were 
  planted 
  in 
  gravel 
  in 
  suitable 
  lagoons 
  of 
  the 
  lake. 
  

  

  The 
  result 
  of 
  the 
  experiment 
  at 
  Uganik 
  seems 
  to 
  justify 
  the 
  con- 
  

   clusion 
  that 
  a 
  suitable 
  site 
  is 
  afforded 
  for 
  a 
  moderate-sized 
  salmon 
  

   hatchery. 
  The 
  sockeyes 
  at 
  Uganik 
  have 
  long 
  been 
  recognized 
  for 
  

   their 
  superior 
  size. 
  It 
  is 
  reported 
  that 
  about 
  48,000 
  sockeyes 
  were 
  

   taken 
  by 
  commercial 
  fishing 
  interests 
  this 
  season 
  from 
  Uganuk 
  Bay. 
  

  

  FORTMANN. 
  

  

  The 
  Fortmann 
  hatchery 
  of 
  the 
  Alaska 
  Packers' 
  Association 
  is 
  

   located 
  on 
  Heckman 
  Lake 
  of 
  the 
  Naha 
  system, 
  8 
  miles 
  above 
  Loring, 
  

   in 
  southeast 
  Alaska. 
  It 
  is 
  the 
  largest 
  salmon 
  hatchery, 
  public 
  or 
  

   private, 
  in 
  the 
  world, 
  having 
  a 
  capacity 
  of 
  upwards 
  of 
  110,000,000 
  

   red-salmon 
  eggs. 
  During 
  the 
  1912-13 
  egg 
  collecting 
  season23,160,000 
  

   eggs 
  of 
  this 
  species 
  were 
  taken, 
  from 
  w^hich 
  during 
  1913 
  a 
  total 
  of 
  

   20,800,000 
  young 
  fish 
  were 
  liberated, 
  the 
  loss 
  being 
  a 
  little 
  over 
  10 
  

   per 
  cent. 
  The 
  fry 
  passed 
  from 
  the 
  hatching 
  troughs 
  into 
  nursery 
  

   ponds, 
  where 
  they 
  were 
  fed 
  on 
  fish 
  prepared 
  for 
  the 
  purpose, 
  and 
  after 
  

   they 
  had 
  attained 
  a 
  growth 
  which 
  enabled 
  them 
  to 
  move 
  about 
  in 
  

   strong 
  and 
  vigorous 
  fashion, 
  they 
  were 
  allowed 
  to 
  pass 
  from 
  the 
  

   ponds 
  into 
  the 
  Naha 
  stream 
  system 
  of 
  lakes 
  and 
  connecting 
  waters, 
  

   most 
  of 
  them 
  to 
  remain 
  there 
  through 
  one 
  winter 
  before 
  going 
  to 
  sea. 
  

  

  The 
  egg-taking 
  season 
  of 
  1913, 
  which 
  extended 
  from 
  August 
  24 
  

   to 
  October 
  16, 
  resulted 
  in 
  the 
  collection 
  of 
  but 
  9,480,000 
  red-salmon 
  

   eggs. 
  This 
  is 
  the 
  poorest 
  take 
  in 
  the 
  13 
  years 
  the 
  station 
  has 
  been 
  

   operated. 
  The 
  situation 
  simply 
  was 
  that 
  the 
  run 
  of 
  breeding 
  salmon 
  

   did 
  not 
  materialize, 
  and 
  bore 
  out 
  the 
  fishing 
  records 
  as 
  well 
  as 
  the 
  

   returns 
  at 
  other 
  hatcheries. 
  Quadra 
  excepted, 
  that 
  southeast 
  Alaska 
  

   had 
  an 
  off 
  year 
  for 
  red 
  salmon. 
  At 
  Quadra,

  60
